How to Display Math Symbols in WordPress…

The difference between MathML, LaTeX, and PHP Math Publisher…
Each of these methods may be used to display mathematical equations on a web page. Both MathML and LaTeX follow standards that have communities of users around them. Unfortunately they both require some significant overhead to use and/or view.
My new plugin called WordPress Math Pub, is based on the PHP Math Publisher library by Pascal Brachet. MathML and LaTeX are not used. This library is an open-source library that converts plain text into image links to mathematical PNG images. The PHP Math Publisher library is a relatively new method for publishing mathematic equations and symbols. It has its own simple text-based syntax that is easy to learn and embed into any web page. New math images are created automatically on the fly from within your WordPress main loop as needed during content display.

Sorry for not getting back to you. I’ve been out of the loop for a while. The thing with word press is the it’s tough for me to figure out how to post the plug-in on their site. I want to give my plug-in away for free (Free Software style). So please don’t think I’m hiding, I’ve just been having trouble with subversion.

Hi Randy:
Here were the steps I took to complete my WordPress plugin:
1) Prepare the special readme.txt with wiki markdown tags such that the WordPress landing page has all content needed: description, installation, FAQ, screenshots, other notes.
2) Follow their SVN beginners guide to stuffing the trunk subdirectory on my local PC with all my plugin code. I had two problems with this initially:
a) This plugin requires the use of an img/ subdirectory that must be on the blogger’s system, but empty subdirectories are ignored (during the download process by a new user trying to aquire my plugin) unless you load something in there. So I put a dummy image in the img/ directory just so users will get that directory. I included the directory structure in my screenshots to help new users quickly understand the details surrounding my plugin, in case they forgot to upload all supporting files and subdirectories onto their server:
http://wordpress.org/extend/plugins/wpmathpub/screenshots/
b) When I tried to commit my initial code to the WordPress repository, several errors were encountered by the SVN CI command. The only help I found was a reference on some site “that an engineer should not upload too much code at once or problems may occur†– and yup problems did occur. To solve these errors, I repeated a series of “stat, del, cp, and ci” statements (not always in that order), until the stat command gave no errors. Then I did a download from my new wordpress.org landing page to see what files I was missing as a result of my “get rid of the SVN errors at all cost†technique. I then did one more round of cp, stat, and ci SVN commands to complete the process.
I hope that helps,
Ron

Hi Roderik:
Can you provide some detail on how wpmathpub plugin interferes with your use of the editors?
So far the only issue has been in the use of greater than “>” and less than “<” symbols – as these are converted by html aware editors to “& gt;” and “& lt;”. This conversion of html symbols can be circumvented by switching from “edit” mode to “code” mode.
Bes regards,
Ron
May 13th, 2008 at 8:46 pm
Switching to code mode does not circumvent it for me. When you edit in code, click save and check what is there, < and > were inserted. The only way might be to turn of the visual editor as a whole in the user settings. However that is quite annoying since I want to write the articles itself in the visual editor.
I think it might work if you write a filter for wordpress that converts the html encoded characters if they are inside a math block.

May 13th, 2008 at 10:08 pm
Hi Roderik:
Thank you for your polite and accurate feedback.
I agree with you that it should be fairly simple to implement the html entities replacement – as you suggest above. I will use our conversation here to drive the next release. It will take me a week or so to get back to this project with a formal update release on the wordpress.org site.

Hi,
Following the previous comments, when using > or < it breaks the post display.
But I am posting comment here to suggest to had math support for comments.
For example by adding that:
add_filter('comment_text', 'to_phpmath', 5);at the end of wpmathpub.

Hi Oliv:
Adding math support to comments is a great idea. I am adding this to the list of TODO’s for a new release comming soon.
Best regrards,
Ron
May 15th, 2008 at 1:06 am
I just checked wpmathpub plugin against WordPress 2.5.1. It works just fine. This change to the readme file will be added to the next release comming soon – too.

May 15th, 2008 at 6:23 pm
I have made two updated candidate changes to my wpmathpub v: 1.0.4 plugin to address the issues presented by Roderik and Oliv in comments above:
1) With this first change, html entities such as “& gt;” are now decoded back to their correct ASCII values. The php function html_entity_decode(), does all the heavy lifting. This was a great idea initiated by Roderik in his comments above. In the GeSHI code highlighter box below you can click on this function name to learn more…
HTML entity decoder fixed in wpmathpub.php plugin
2) With this second change, wpmathpub tags [pmath size=xx] can be used in blog posts and in comments too, as this comment demonstrates below. To affect the support for pmath tags in comments, only one new line of code was needed. This was a great idea by Oliv in his comment above. See the new line of code in the GeSHI code highlighter box below…
pmath tag support for comments added in wpmathpub.php
I discovered and resolved two issues before pmath tags would work properly once comment support was added:
Demonstration
So Oliv’s pmath test case (with a “& gt;” entitiy hard coded)…
sum{i=1}{n}{C(q_i)}>C(sum{i=1}{n}{q_i})
and the same test case (with a “>” symbol hard coded)…
sum{i=1}{n}{C(q_i)}>C(sum{i=1}{n}{q_i})
now display correctly with the “& gt;” entity converted back to text for correct conversion to mathematic symbols…
and with “>” symbol …
How to get the code changes
If you want to make the changes to your own plugin now, all you have to do is copy the two code snippets above. Then, put them into the current wpmathpub download, version 1.0.4, as I did to make this comment work correctly with html entities. While, a new download under WordPress.org’s subversion control will be coming out soon.
Best regards,
Ron

Hi Ron,
Very cool plugin, but I’m having a problem. Wpmathpub installed and ran fine on my localhost server, but when installed on my website, posts don’t load past the post heading (title, date, etc.). Page loading just hangs at this point. No error message, just fails to complete loading.
Tried the normal stuff: deactivate/activate, disable other plugins, switch to default theme, delete and reinstall the plugin files, no luck. Images are not being written to img directory (which is 755).
wpmathpub 1.06, wp 2.51
Any suggestions?

This is on WP 2.6 so is this a compatibility problem or something else?

August 1st, 2008 at 9:21 am
Hi Craig:
As you can see from the display, your [pmath ...] tag works fine on my blog. As you point out, I am using WordPress 2.5.1. I have tested several prior versions but have not yet had a chance to verify compatibility with 2.6 yet. It could take another two weeks before I make this test.
In the meantime I do have a diagnostic version of the plug-in that helps identify potential sources of error based on installation and damaging effects from other plug-ins. I could email this version to you if you like?
Best regards,
Ron
September 7th, 2008 at 7:38 pm
With over 700 downloads of wpmathpub, I decided I should continue to support this plugin. Version 1.0.7 has just been released to wordpress.org’s plugin pages. The new version includes a diagnositc display to help new users resolve their initial install problems.
You can get it here:

Hi there.. i really like this plugin, but i have what i hope is a simple question.
my blog’s background is black, and the theme i am using is trying to put the output in a light grey and is messing things up. is there a way to have the output in white? or any color for that matter….
-tyler
September 24th, 2008 at 9:39 pm
Hi Tyler:
What you ask for seems obvious in hindsight, thanks for the suggestion. Control of forground color, background color, and both of these color transparencies, is very “do-able” since all controls are handled by the PHP GD library. The necessary step is to add these color controls as seen on http://www.php.net into the wpmathpub.php plugin code:
imagecolorallocate
imagecolortransparent
imagecolorallocatealpha
I will put this feature request on the list for next release.
Best regards,
Ron
October 21st, 2008 at 8:56 pm
Besides being able to control the background (I believe transparent background is the most useful), we also need the plugin to add a special CSS image style so that we can control the appearance of the math separate from the style of the rest of the images.
In my blog I have my images surrounded by a frame so the math shows up with the frame as well.
Ideas?
October 27th, 2008 at 9:19 pm
Hi AB:
Adding more style control is a good idea. I’m still wrapping my head around your suggestion with respect to actionable features. For example: below is what the HTML code looks like from Craig’s inline math comment above (with angle brackets removed to insure no rendering action takes place):
img src="http://www.embeddedcomponents.com/blogs/wp-content/plugins/wpmathpub/phpmathpublisher/img/math_965_6427aababa4e7b39af22b31fc6504152.png" style="vertical-align:-35px; display: inline-block ;" alt="S(f)(t)=a_{0}+sum{n=1}{+infty}{a_{n} cos(n omega t)+b_{n} sin(n omega t)}" title="S(f)(t)=a_{0}+sum{n=1}{+infty}{a_{n} cos(n omega t)+b_{n} sin(n omega t)}"From the code you can see the existing style control calculated on the fly to best fit the surrounding text:
Are you proposing the addition of some class=”id_thing” entries that are configurable as part of the wpmathpub blog plugin?
Best regards,
Ron
November 17th, 2008 at 11:35 am
What I am proposing is that the math images are (maybe optionally) tagged as some class=”mathpub_img” or something so that we can control their CSS style separately from the “img” class.
Maybe you have a better idea. What I want is for my equations to show as transparent BG (or at least BG color) while my regular images show with a frame around them.
November 20th, 2008 at 8:57 pm
Oops:
One new user posted a message explaining how wpmathpub failed to configure itself properly. The user was very clear in showing the path details and what he did to solve this error. This type of error caught my attention after 1000 new uers have downloaded my plugin with nearly all having an error free experience.
Sorry but I deleted you by mistake. Please post again if you get a chance. In the mean time, I will try a few combinations on my own. If I find any issue in my config system, I will roll a fix into the next release.
Best regards,
Ron

Hi AB:
Thanks for clarifying the CSS style feature you are proposing. I will be experimenting with this over the next few weeks.
Best regards,
Ron

Hi,
Very good plugin.
I can’t find how to change the color of the formula text. Is it possible?
Best regards.
December 18th, 2008 at 1:04 am
Hi Anu:
I suspect you have a problem with the fonts installed from my plugin code on your server. The fonts directory would be located here:
http://diabolicalorsmart.com/wp-content/plugins/wpmathpub/phpmathpublisher/fonts/
ImageTTFBBox() is a basic php function supplied by your server. It is documented here:
http://www.php.net/imagettfbbox
The common denominator seems to be the use of fonts.
I suspect your phpmathpublisher/fonts directory is not readable. Can you test this on your server?
December 28th, 2008 at 4:40 pm
Hi There.
I found a slight bug in my install. I was finding that it would work when I went to a page directly but not from my root directory.
The way my website runs is that the wordpress install is not in the public_html directory. Instead it runs from a ./blog directory under it with my index.php pulling up the wordpress header using
What I needed to do to make it work was change the code where you set up the depth and dirimg etc
$depth=(end(explode(“/”,getcwd())) == “wp-admin”) ? “..”: “.”;
To
$depth=(end(explode(“/”,getcwd())) == “blog”) ? “.”: “./blog”;
What I couldn’t work out was the scenario when you would be calling the script from wp-admin. Would you ever be in that directory?
Anyway the script change works for me. A general fix would need to identify the name of the install dir under public_html and use that.
Thanks for the script by the way. Makes life a lot easier
December 28th, 2008 at 5:43 pm
Hi Brenton:
Interesting work, thanks for sharing your situation. When making changes, I suggest testing these use cases:
1) math symbol creation in body of post (most common case)
2) math symbol creation in comment to a post
3) math symbol display from RSS feeds (posts and comments)
4) math symbol display from admin dashboard view of comments
December 28th, 2008 at 7:31 pm
Thanks I didn’t think of the comments.
The solution which works for me using all the use cases you mentioned is as follows. It is a hack I am afraid. My php is many years rusty. Couldn’t even remember how to concatenate doh!
It will need a longer term fix to automatically identify the directory that wordpress is installed in.
I am using public_html/blog, but there is no guarantee that anyone else is using this.

January 21st, 2009 at 5:24 am
I am very excited about this plug-in and I am going to use it on the my blog. There are some things that have been overlooked however, which might be to do with the available fonts. Is their support for vectors or bold characters?
Also missing characters often used by physicists, such as the dell or nabla operator and hbar.
January 24th, 2009 at 1:49 am
Hi Ned:
You bring up a great point. Curl, Dell, Nabla, and hbar seem to be missing from the phpmathlibrary fonts. Vectors themselves can be expressed however. See the list of available symbols from here:
http://www.xm1math.net/phpmathpublisher/doc/help.html
With vector constructor demonstrated in lower right column. Your identification of the missing physics symbols is a great feature for future release – thanks for that.

Hi Ron
Nice plugin but I am having problems with in-line formulas. It seems to place symbols at the start of the next line, not at their position within the text. Here is an example:
(E), graphed in the figure below.

Any help appreciated.

February 6th, 2009 at 10:46 am
Hmmm … that’s interesting. The code was rendered correctly in my comment above. Different version of wordpress?? My web host provides v. 2.5.1. Any other ideas?
February 13th, 2009 at 3:21 pm
Hi Bob:
Thanks for your question. In general, formatting problems tend to be related to CSS controled by your page header template or table/div tag code body layouts. This is true for any image in any HTML page. Your sample jpg above is not a clear demonstration of any problem, maybe because it is too short. Your comment above with your mu seems to work fine probably because there is text above and below – sort of a lucky break that may not be useful – or my blog template is better suited to getting the format right on its own. To encourage accurate code design, try using a table for each line of text with wpmathpub images embedded that fail to format the way you want on its own.
Take a look at my blog post here to see what I mean (just after figure 1):
http://www.embeddedcomponents.com/blogs/2008/04/74hc193-for-ltspice-switchercadiii/
To see what I mean, use your view source link in your browser to see how I have used tables to control my formatting of wpmathpub images. Other bloggers may disagree and desire to use div tags instead of table tags – that’s fine too. But the key is that formatting requires some effort on your part when automatic formatting fails on its own. My formatting did not change when I moved from version 2.5.1 to 2.7 so I do not think this has anything to do with it.
I hope that helps,
Ron
February 14th, 2009 at 2:11 am
Is there a quick workaround for changing the colors?
February 15th, 2009 at 11:12 am
Hi Ron
Thanks for the reply. Although your plugin helps a great deal, it looks like math in html is no cakewalk. I will keep in mind your suggestion to use tables to “nudge” the formatting.
For simple stuff like my letter mu &mu or the right arrow in your example, it seems simpler to use the Html 4.0 symbols, &mu and &rarr , although they are not by supported older browsers.

Hi Ron,
i cant seem to get the plugin to work. I was really excited when I found this plugin because now i can add formulas online!
However, i cannot get the same result as what you got in screenshot 5.
i.e. “img directory readable” -> “mathfilter” does not appear for me.
Please help! I am currently using WP version 2.7…
Also, when I attempt to key in the formulas and publish the blog, no content appears. Only the blog title.
I hope to hear from you regarding this issue soon!
Thanks in advance Ron!
May 16th, 2009 at 1:36 am
Hi Jeremy:
Thank you for your interest and initial install attempt with WPMathPub. If I understand you correctly, when you display your wpmathpub status from your admin tool, you do not get “img directory readable” = yes.
If this is the case, you will likely need to manualy go to the img directory and make it readable. This “how to” can be found in my FAQ located here:
http://wordpress.org/extend/plugins/wpmathpub/faq/
“During installation how can I make sure the ‘img’ directory has write access?”
May 16th, 2009 at 8:44 am
Hi there Ron,

Im tried changing the autochmod to false but still no change. However, because I am not very experienced with this, Im not too sure how to do the SSH BASH thing.
What else can be done? Please advise! Thank you!

Thanks for an excellent plugin, worked for me ‘straight out of the box’!
Bing new to the Php Math Publisher command set, I found I was continually referring to the help web page, so I did myself a pdf of it. Just though it might be useful for others, if so they can find it here: http://www.mark-wilson.net/?p=483

Hi,
Your plugin works great, except that when I add text in between two pmath tags, the text doesn’t seem to show up. For example:
Consider the geometric sequence 2, 4, 8, 16, …
On my site, the text “Consider the geometric sequence…” is not there.
It simply has the two lines of math equations, but does not display the text.
What am I doing wrong? Thanks.
October 24th, 2009 at 3:50 pm
Hi Devin:
As you can see from your own comment just above this one – text entered between two math graphics generated with [pmath ... /pmath] tags displays just fine.
What might have happened during your blogging experience is that you did not choose an HTML tag to enclose your text. Sure wordpress makes it a little easier and a lot more automatic to enter text into a blog post. But when you experience a problem, such as missing text as Devin has encountered, here is a simple solution to enforce correct display of your text….
Put your text into an HTML paragraph tag like this:
<p >Consider the geometric sequence 2,4,8, 16, 16…</p>
Choose one of these two approaches to get these paragraph tags into your blog post yourself:
1) Use your editor’s raw HTML mode to enter the “less than” and “greater than” symbols manually or
2) use the editor’s “paragraph” menu option from your editor’s VISUAL mode.
If you view the HTML source code for this page using your browser’s view->source feature you would see that that is exactly what WordPress automatically choose to correctly format his text string in the comment above.
The problem /solution I describe here has more to do with HTML text entry for a web page (like a blog post) than with my wpmathpub graphics publication. I hope this helped Devin,

February 9th, 2010 at 11:01 am
Hi Ron,
thanks for the great plugin. I’ve tried 1.0.7 on WP 2.9.1 and I had two issues:
1. I had to chmod 777 the img directory, because the web server apparently ran under a different userID than my account.
2. There’s no diagnostic/settings/manage entry in the Plugins->Manage menu. Only the points to activate and deactivate the plugin.
But everything else seems to work just fine. Thanks a lot.
March 30th, 2010 at 11:39 pm
Thanks Farid:
The chmod should be automatic as reported by most users. There still may be a bug in the logic around this feture in my code so point well taken here.
I suspect your point here is a good find and I hope to verify your findings soon and post a new release.
Also see Phil’s comment for an additional problem and work around for those who try and use the “minus” sign in comments with WP release 2.9.2:

Dear Ron,
I’m getting an unfortunate font display issue – the bottom of my ps and qs are being cut off. An example is at http://www.alisterair.com/techniques/lagrange-method/ (under the headings “Marshallian demand functions” and “First order conditions”). The bit that looks fine isn’t being generated by WPMathpub – that came from a LaTeX to gif web site somewhere.
Any ideas?
Thanks,
Alister
