Title: WPMathPub Author: Ron Fredericks Published: March 28, 2008 Last modified: March 26, 2026 --- Search plugins ![](https://ps.w.org/wpmathpub/assets/banner-772x250.jpg?rev=997722) ![](https://ps.w.org/wpmathpub/assets/icon-256x256.jpg?rev=2822044) # WPMathPub By [Ron Fredericks](https://profiles.wordpress.org/ronf/) [Download](https://downloads.wordpress.org/plugin/wpmathpub.3.0.2.zip) * [Details](https://pcd.wordpress.org/plugins/wpmathpub/#description) * [Reviews](https://pcd.wordpress.org/plugins/wpmathpub/#reviews) * [Installation](https://pcd.wordpress.org/plugins/wpmathpub/#installation) * [Development](https://pcd.wordpress.org/plugins/wpmathpub/#developers) [Support](https://wordpress.org/support/plugin/wpmathpub/) ## Description WPMathPub renders mathematical equations in WordPress using the **mathpublisher rendering engine**, supporting both **pmath native syntax and LaTeX-style input** and generating high-quality PNG images with transparent backgrounds. Unlike MathJax-based plugins, WPMathPub performs **server-side rendering**, producing static equation images that display consistently across browsers and devices without requiring client-side JavaScript. This approach provides reliable rendering for: * WordPress posts and pages * RSS feeds * Cached pages * Environments where JavaScript rendering is not desirable WPMathPub extends the classic mathpublisher engine with modern WordPress integration including shortcode support, LaTeX translation, image caching, and configurable rendering options. ### Mathematical Equation Rendering Mathematical expressions can be embedded directly into WordPress content using the pmath shortcode. Example: ``` [pmath]x^2 + y^2 = z^2[/pmath] ``` Custom size and color: ``` [pmath size=18 color="blue"]E = mc^2[/pmath] ``` LaTeX input: ``` [pmath latex=1]\frac{a}{b}[/pmath] ``` Expressions are rendered as PNG images using the GD and FreeType libraries and cached for efficient reuse. ### Features * pmath expression rendering * LaTeX command translation (PHPMathPublisher subset) * Server-side PNG equation generation * Gutenberg WPMathPub math block with PMath and LaTeX mode switching * Halo-free color rendering with alpha transparency * Transparent background support for dark themes * Minimal WordPress database footprint * Efficient PNG image caching * WordPress admin tools panel - Configurable default equation size - Configurable default equation color with color picker - Installation status display - PNG image cache status and control - Policy control for cleanup on plugin delete ## Screenshots * [[ * Example rendered equation in page * [[ * Example rendered equation in comment * [[ * Example Gutenberg block * [[ * Example from syntax page * [[ * WordPress admin configuration panel top * [[ * WordPress admin configuration panel bottom ## Blocks This plugin provides 1 block. * Math (WPMathPub) ## Installation 1. Upload the plugin folder to the `/wp-content/plugins/` directory. 2. Activate the plugin through the WordPress Plugins menu. 3. Optional: change defaults under **Tools WPMathPub**. ## FAQ ### How do I get started with WPMathPub? Here are two references: * Check out the [WPMathPub math publisher page](https://www.biophysicslab.com/wordpress-math-publisher-plugin/) for the user guide. * Check out the [WPMathPub syntax page](https://www.biophysicslab.com/wordpress-math-publisher-plugin/wpmathpub-syntax/) for a complete cross-reference of all pmath native and LaTeX supported commands. ### Does this plugin require MathJax? No. WPMathPub renders equations server-side as PNG images using the mathpublisher rendering engine. ### Does it support LaTeX? Yes. Many LaTeX math commands are translated into pmath syntax before rendering. See the syntax reference page for the full list of supported commands. ### Where are rendered images stored? Rendered equation images are cached in: ``` /wp-content/uploads/wpmathpub/math-img/ ``` ### Why does the plugin generate PNG images instead of SVG? The plugin preserves compatibility with the mathpublisher rendering engine, which produces raster images. PNG output ensures consistent rendering across browsers. ## Reviews ![](https://secure.gravatar.com/avatar/b188f9243124fb886e9fd19a6b9b50aa820c346b4278cddde528bb44f47ae969? s=60&d=retro&r=g) ### 󠀁[Not compatible with wordpress 4.9.8](https://wordpress.org/support/topic/not-compatible-with-wordpress-4-9-8/)󠁿 [anchorn9852](https://profiles.wordpress.org/anchorn9852/) November 23, 2018 it gives me error: Fatal error: Uncaught Error: Call to undefined function ereg() in ….web/wp-content/plugins/wpmathpub/phpmathpublisher/mathpublisher.php:1604 Stack trace: #0 /nfsmnt/hosting1_1/4/c/4cdba5d2-b725-4d56-95e7-7244c2ed5f96/dveadvesustyri. sk/web/wp-content/plugins/wpmathpub/phpmathpublisher/mathpublisher.php(1625): detectimg(‘ 629fdc23df6a73c…’) #1 /nfsmnt/hosting1_1/4/c/4cdba5d2-b725-4d56-95e7-7244c2ed5f96/ dveadvesustyri.sk/web/wp-content/plugins/wpmathpub/phpmathpublisher/mathpublisher. php(1661): mathimage(‘S(f)(t)=a_{0}+s…’, ’12’, ‘http://dveadves…’) #2 /nfsmnt/hosting1_1/ 4/c/4cdba5d2-b725-4d56-95e7-7244c2ed5f96/dveadvesustyri.sk/web/wp-content/plugins/ wpmathpub/wpmathpub.php(110): mathfilter(‘S(f)(t)=a_{0…’, ’12’, ‘http://dveadves…’)# 3 [internal function]: wpmathfilter(Array) #4 /nfsmnt/hosting1_1/4/c/4cdba5d2-b725- 4d56-95e7-7244c2ed5f96/dveadvesustyri.sk/web/wp-content/plugins/wpmathpub/wpmathpub. php(124): preg_replace_callback(‘#\\[pma in /nfsmnt/hosting1_1/4/c/4cdba5d2-b725- 4d56-95e7-7244c2ed5f96/dveadvesustyri.sk/web/wp-content/plugins/wpmathpub/phpmathpublisher/ mathpublisher.php on line 1604 ![](https://secure.gravatar.com/avatar/f58ac795471e4b516970127e7bedf6b39fe32c16b3c2047a253fe716aed8037a? s=60&d=retro&r=g) ### 󠀁[Very useful](https://wordpress.org/support/topic/very-useful-969/)󠁿 [thy92](https://profiles.wordpress.org/thy92/) September 3, 2016 Very useful to use.

Backslashes are sometimes stripped in WP leading to formulas not showing properly.
