## Description
LaTeX2HTML makes you write blog like in LaTeX doc. You can just copy and paste to
create a new post in WP from your tex source file, then it will looks like `amsart`
document style. It support a lot of raw latex command including theorem like environment
and BibTeX style citation.
### Main Functions
* Enable [MathJax](https://www.mathjax.org) to render math formula.
* Translate raw LaTeX (almost all the command of amsart) to HTML+CSS markup.
* Almost every thing is customizable, but also works perfect by default. e.g.,
support \newcommand
### License
Good news, this plugin is free for everyone! Since it’s released under the GPL2,
you can use it free of charge on your personal or commercial blog.

## Installation
1. (Recommend: Automatically installation) If you install from WP plugin page, just
search `latex2html` and click Install.
2. (Manually installation) Extract the zip file (that’s you will get `latex2html`–
A file directory) and just drop it in the `wp-content/plugins/`directory of your
WordPress installation
3. Then activate the Plugin from Plugins page.
4. (Optional) Do the [Test Example](https://wordpress.org/extend/plugins/latex2html/faq/)(
see FAQ).
## FAQ
Any question can be feed back at there (turn to the `support` pannel)
1. After you updating to WordPress 5.0 or higher, in the new new block editor, you
can switch to HTML code mode from Visual mode by `Ctrl+Shift+Alt+M`. Or you can
use the [Classical Editor](https://wordpress.org/plugins/classic-editor/).

### A Test Example
For a test, you can do the following:
```
\title{Hello LaTeX2HTML}
\begin{thm}[Newdon-Leibniez]\label{thm:NL}
If $f\in C^1([a,b])$ then
\begin{equation}\label{eq:NL}
\int_a^b f'(x) d x=f(b)-f(a)
\end{equation}
In \autoref{thm:NL} the main part is \eqref{eq:NL}.
\end{thm}
```
Add a new post (it should be in the `HTML` code mode rather than the `visual` mode),
copy the code into your new post, then preview it.
In fact, after a while you will find that it almost as if you were write your `TeX`
doc rather than a post!
### How can I report security bugs?
You can report security bugs through the Patchstack Vulnerability Disclosure Program.

### [This is one of the best plugins ever](https://wordpress.org/support/topic/this-is-one-of-the-best-plugins-ever/)
[gene172](https://profiles.wordpress.org/gene172/) November 3, 2023
This is one of the best plugins ever for both LaTeX and WordPress users. While the
LaTeX part is close to perfection, references still need some refinements to match
the quality of the main part.
### [Very straightforward](https://wordpress.org/support/topic/very-straightforward-2/)
[ellankavi](https://profiles.wordpress.org/ellankavi/) January 3, 2019
I tried a couple of LaTeX plugins for my version of WP (v5), none of which worked
as expected (I didn’t try very hard to find out why). But this one worked straight
out of the box. Very intuitive and easy to use. Kudos!
### [The best LaTeX plugin in WordPress I’ve seen](https://wordpress.org/support/topic/the-best-latex-plugin-in-wordpress-ive-seen/)
[guiqiqi](https://profiles.wordpress.org/guiqiqi/) November 16, 2018
Awesome! Thanks author of this plugin. You can just copy your LaTeX code into your
new article without any edition, and this plugin will help you to generate a beatiful
output.

我找了很多的数学公式的插件 基本上没有哪个支持这种格式的行内公式： $E=mc^2$ 唯独那个
qicklatex支持，但那个只能图片显示公式，速度慢 突然发现这个插件，特别好！完美支持！
谢谢作者！

A nice plugin! [ link redacted ] And I have some suggestions for improvement: (1)
The reference cannot be download; (2)I know that you have develop functions for
preview latex codes, why not share it as another plugin or integrate them into this
plugin; (3)Add a option: A blank line for new line.

## Changelog
#### 2.6.2
* Improved LaTeX-style comment handling (`%`) to ignore content after `%` in plain
text while preserving it inside HTML tags.
* Fixed handling of `%` inside URLs, escaped `\%`, and HTML attributes like `style
="..."`.
#### 2.6.1
* Resolved an issue where the MathJax configuration was breaking the formula display
by outputting it as raw text.
* Applied proper sanitization using wp_kses to ensure safe and correct rendering
of MathJax formulas.
#### 2.6.0
* This version includes important improvements to file handling, caching, and security.
It is recommended to back up your bibtex data before upgrading. After upgrading,
check the plugin settings to ensure everything is configured correctly.
* Improved file handling for bibtex data by utilizing the WordPress filesystem
API, which enhances compatibility and provides better error handling compared
to direct file operations.
* Implemented caching for bibtex queries to improve performance by reducing the
number of database queries and speeding up the retrieval of bibtex items.
* Enhanced security measures by sanitizing and validating user inputs more thoroughly,
including the use of nonces for form submissions and verification of user permissions.
* Updated the plugin’s version number to 2.6.0 and changed the last update date
to 01/10/2025.
* Modified the bibtex data writing process to append data to the bibtex.bib.txt
file using the WordPress filesystem API, ensuring proper file permissions and
error handling.

function.
* Improved the handling of LaTeX commands and styles by escaping output to prevent
potential security vulnerabilities.
* Enhanced the parsing of footnotes in LaTeX content, including better handling
of nested braces and LaTeX references.
* Updated the LaTeX2HTML settings page to include nonce verification for added
security and to ensure that only authorized users can access the settings.
* Improved the display of error messages and notifications on the settings page
by using WP_Error objects and displaying user-friendly messages.
* Updated the plugin’s localization support by using esc_html__ and other escaping
functions to ensure that translated text is properly sanitized.

for database queries and simplifying conditional statements.
#### 2.5.5
* Security Fix: Patched a Cross-Site Scripting (XSS) vulnerability related to unsanitized
user inputs in URL parameters.
* Sanitized and validated `$_GET['status']` and `$_GET['message']` parameters to
prevent potential XSS attacks.

prevent SQL injection risks.

#### 2.5.4
