1. How to Write the Basic Information of Your Post
Just as in LaTeX, you can use commands such as:`\title`

, `\author`

, `\address`

, `\date`

, `\keywords`

and the environment `abstract`

to produce the basic information of your post. These command has the same meaning as in LaTeX, what’s more,

- you can use
`\`

`today`

in`\date`

- you can use
`\emph`

to emphasis some thing - you can use
`\`

`tableofcontents`

to get the table of contents - you can use
`\email`

or`\mailto`

to set your mail, the first will be centered

Just like in Latex, isn’t it? Replace `\section`

with `\subsection`

and `\subsubsection`

if you want to write subsection and subsubsection, respectively. How about `\subsubsubsection`

? Sorry, there is no such command.

Maybe you are still wandering: how do I get the list of contents by `\`

`tableofcontents`

command, one key factor is that I added a link just before each section and subsection, by which you can refer to it. See the referring back to Section 8.3 for detail.

3. Itemize and Enumerate: How to List Stuffs
As you have already saw, we can list the element with the same syntax as latex. What’s more, it support nested list:

What’s more you can nest them, for example

- Firstly
- Secondly
- The first item of Second
- The second item of Second
- The first item of the third item of second item

`Enumerate`

works almost the same as `itemize`

, except the style is different. For example replace `enumerate`

in the above example with `enumerate`

, then we get:

- Firstly
- Secondly
- The first item of Second
- The second item of Second
- The first item of the third item of second item

`\footnote`

in latex2html with the version newer than 2.1.2, which will transform footnote into superscript with a hyperlink to its content at the end of post. Also `\footnotemark`

and `\footnotetext`

are supported (they are used when footnote is used in formula), but as MathJax can’t parse math when there are html tags, the footnote in formula is not hyperlinked (I add blue color to distinguish it).5. The Color Scheme: How to Colorize You Content As we have already showed that you can emphasis you content by

`\emph`

, one other way is use `\underline`

. Besides, there is a more powerful scheme, now you emphasis some content with different colors, even for formulae.Firstly, you must decide which class your content belonged to, the text content or the mathematics content, since these two classes are processed by different scheme, text is by

`latex2html`

and mathematics by `mathjax`

.Just as in Latex, the you can set a color for your formula by

`\color`

`{color_name}`

`{color_formula}`

. For example\[

\color{red}{a+b},\quad\color{blue}{a+b},\quad\color{green}{a+b}

\]

\[

\frac{\color{cyan}{a+b}}{c+d}, \quad

\frac{a}{\color{magenta}{a+b}},\quad

\frac{a}{a+\color{yellow}{b}}

\]

On the other hand, if you want to give color for your text content, then you should use

`\textcolor{color_name}`

`{color_contents}`

, for examplered and blue and green and cyan and magenta and yellow.

6. The Figure Environment In LaTeX2HTML version 2.1.0, I have add the ability to proceed

`figure`

environment. As an example, you can use
1 2 3 4 5 6 7 |
\begin{figure}[!htbp] \centering \includegraphics{myfig.png} \caption{Just a test} \label{myfig} \end{figure} From the \autoref{myfig} we can see… |

Two important things to be noted:

- You must use the fullname of the figure, i.e.
`myfig.png`

; NOT`myfig`

, since in the later case, we don’t know which figure is to be inserted here; - after that you MUST upload the exact figure (named
`myfig.png`

in the example) to your WordPress as usual. All the later process is handled by LaTeX2HTML plugin, you can just preview to see the results.

Of course the border is not so strict, for example the examp environment can used in both cases.

Here are the complete list of environments you can use (The example will be pop up at some time later), I take first few words of a environment to represent it, for example thm for Theorem:

- First group:
`defn`

(Definition),`lem`

(Lemma),`prop`

(Proposition),`thm`

(Theorem),`cor`

(Corollary),`rem`

(Remark),`excs`

(Exercise),`proof`

(Proof) - Second group:
`prob`

(Problem),`answer`

(Answer) - Mixed:
`examp`

(Example),`quote`

(Quotation)

7.1. Definition, Lemma, Proposition, Theorem, Corollary, Remark, Proof Firstly, you should keep in mind that: the distinguish between command and environment is

A7.1.1. Basic Usage of Environments Here is an example of`command`

begin with a`\`

and followed with the`name`

, at last the content of command. It looks like`\`

`emph{text}`

; A environment must be wrapped by`begin`

and`end`

.

`definition`

environment:The other is similar, just replace

`defn`

with any one of the above environment:- For every open set $V$ in $Y$, the inverse image $f^{-1}(V)$ is measurable.

7.1.2. Assign a Name for Your Theorem You can even assign a name to these environment, just as you did in latex, use

`[text]`

just behind the environment, for example:7.1.3. The Proof Environment The following are the

`proof`

environment, and some more examples, if you are impatient to other contents, then just skip this subsection by click Section 7.2.\[

\|f_m-f_n\|_1< \frac{1}{2^{2k}}.

\]

We let our subsequence be $g_k=f_{N_k}$, taking the $N_k$ inductively to be strictly increasing. Then we have for all $m,n$:

\[

\|g_m-g_n\|_1 \]

We shall show that the series

\[

g_1(x)+\sum_{k=1}^\infty\left(g_{k+1}(x)-g_k(x)\right)

\]

converges absolutely for almost all $x$ to an element of $E$, and in fact we shall prove that this convergence is uniform except on a set of arbitrarily small measure.

Let $Y_n$ be the set of $x\in X$ such that

\[

|g_{n+1}(x)-g_n(x)|\geq\frac{1}{2^n}.

\]

Since $g_n$ and $g_{n+1}$ are step mappings, it follows that $Y_n$ has finite measure. On $Y_n$ we have the inequality

\[

\frac{1}{2^n}\leq|g_{n+1}-g_n|

\]

whence

\[

\frac{1}{2^n}\mu(Y)=\int_{Y_n}\frac{1}{2^n}\leq\int_X|g_{n+1}-g_{n}|\leq\frac{1}{2^{2n}}.

\]

Hence

\[

\mu(Y_n)\leq\frac{1}{2^n}.

\]

Let

\[

Z_n=Y_n\cup Y_{n+1}\cup\cdots.

\]

Then

\[

\mu(Z_n)\leq \frac{1}{2^{n-1}}.

\]

If $x\not\in Z_n$, then for $k\geq n$ we have

\[

|g_{k+1}(x)-g_k(x)| \]

and from this we conclude that our series

\[

\sum_{k=n}^\infty\left(g_{k+1}(x)-g_{k}(x)\right)

\]

is absolutely and uniformly convergent, for $x\not\in Z_n$. This proves the statement concerning the uniform convergence. If we let $Z$ be the intersection of all $Z_n$, then $Z$ has measure $0$, and if $x\not\in Z$, then $x\not\in Z_n$ for some $n$, whence our series converges for this $x$. This proves the lemma.

7.1.4. More Examples of Environments

\[

\int_X f_n\rd\mu

\]

are bounded. Then $\set{f_n}$ is a Cauchy sequence, and is both $\mathcal L^1$ and almost everywhere convergent to some function $f\in\mathcal L^1$.

7.2. The Problem, Answer Environments The second group of environments are provided for discussion, after all, this is a discussion platform. They are:

`prob`

for Problem, `examp`

for Example, and `answer`

for Answer.It almost works the same as the first group, for example

But, the differences between them is that, the

`answer`

is numbered with `prob`

(the `examp`

, `excs`

, `rem`

will numbered independently), to see this, for example:You should note that the number of answer is reset to 1 by

`prob`

, of course, more sensible. For example:7.3. The Exercise Environment Maybe, at somewhere, you want the reader consider about something, then you can use

`excs`

environment for Exercise. *Please keep in mind that it will have independent numbering, just as*. Here is an example:

`prob`

, but will not reset the number of answer7.4. The Quote Environment Sometimes, there are some words or comments on the content, it is like a remark, but it is not so formal. And, if you are write a lecture notes, these words may be the lecturer said before or after an important thing, such as theorems. I have defined a new environment

`quote`

to deal with these stuff. For example:Before the theorem

- If $u\in C^2(\Omega)$ is harmonic in $\Omega$, then $u$ satisfies MVP;
- If $u\in C(\Omega)$ satisfies MVP, then $u$ is smooth and harmonic.

we want to add a comment on it, then you can use the

`quote`

environmentA function satisfying mean-value properties is only required to be continuous. However, a harmonic function is required to be $C^2$. Thus, the equivalence of this two kind of functions will be significant.8. Auto Numbering and Referring Back The plugin supports two groups of referring back, the first is for

`section`

and theorem environment e.g. `thm`

. The second is done by mathjax, which support math formulae auto-numberring .8.1. Auto Numbering and Referring Back to Equations All the

`mathematical`

environments: `equation`

, `align`

, `multline`

, `gather`

will auto-numbering. For example\begin{equation}\begin{cases}

3=2x+y\\

3=y+2x\end{cases}

\end{equation}

An example of

`multline`

, which will make the last line flush right:\begin{multline}\label{eq:2}

\int_a^b \biggl\{ \int_a^b [ f(x)^2 g(y)^2 + f(y)^2 g(x)^2 ]

-2f(x) g(x) f(y) g(y) \,dx \biggr\} \,dy \\

=\int_a^b \biggl\{ g(y)^2 \int_a^b f^2 + f(y)^2

\int_a^b g^2 – 2f(y) g(y) \int_a^b fg \biggr\} \,dy

\end{multline}

The next example will show how to numbered the equation at a given line with

`\tag{4.a}`

:\begin{gather}

\begin{split}

\varphi(x,z)

&= z – \gamma_{10} x – \sum_{m+n\ge2} \gamma_{mn} x^m z^n\\

&= z – M r^{-1} x – \sum_{m+n\ge2} M r^{-(m+n)} x^m z^n

\end{split}\tag{4.a}\label{eq:4a}\\

\begin{split}

\zeta^0 &= (\xi^0)^2, \\

\zeta^1 &= \xi^0 \xi^1

\end{split}\notag

\end{gather}

8.1.1. How to Refer back to Equation Number If you want to refer the equation, you can add a label

`\label{eq:4a}`

, and rerer as `\eqref{eq:4a}`

, it looks as \eqref{eq:4a}.8.1.2. My Suggestion on “How to Write Equations”

- if you use
`>`

or`<`

for`greater`

and`lesser`

in math, please add a blank-space before`>`

and a blank-space after`<`

. Or you will make the HTML translation program confused, since are standard tags for HTML language(code). - use
`$$`

for inline math - use
`\[`

`\]`

for oneline unnumbered display math - use star version for multiline unnumbered display math, for example, use
`gather*`

environment for centered multiline equations - use
`equation`

environment for oneline numbered display math - use
`align`

environment for multiline numered display math, if you want make them aligned at some position( use & to set the point of align)

`proof`

are auto numbered by `latex2html`

, and the `rem`

, `prob`

, `excs`

, `claim`

are numbered independently, what’s more, `answer`

’s number will be reset by `prob`

. The other environment will numbered continuously in one post (on one page, which means, if you use the `<!–nextpage–>`

to have another page, then the number will all over begin from 1, if you consider this as an bug, sorry, I can’t fix it.)8.2.2. Referring Back to Environments You can refer to the

`Theorem`

, `Lemma`

, `Corollary`

, `Definition`

, `Proposition`

, `Remark`

, `Problem`

, `Exercise`

, and `Answer`

environments by:- first add a
`\label{thm:labnum}`

- and use
`thm:labnum`

or`thm:labnum`

to refer back

From Proposition 5 we know that…

From Answer 2.1 we know that…

8.3. Referring Back to Section You can use

`\autoref`

`{sec:1}`

to refer back to Section 1, and `\ref`

`{sec:6.1}`

to refer back to Subsection 1 of Section 6, which will looks like 8.1, and `\autoref`

`{sec:621}`

to refer back to Subsubsection 1 of Subsection 2 of Section 6, which will looks like Section 8.2.1.9. BibTeX Citations The main new feature of version 2.0.0 is add the BibTeX citation support. By which, you can cite references like in LaTeX.

9.1. How to Add BibTeX Data To add the bibtex data, just turn to the

`LaTeX2HTML`

setting page, under the `BibTeX`

table, you can paste you bibtex data into the input box.
I have add an example data. Also try to double click to restore the last content in the input box.

9.2. How to Cite
`LaTeX2HTML`

support `\nocite`

, `\cite`

and `\citeauthor`

, all of them require the exactly `bibkey`

(which means `\`

`nocite{*} `

will not work and it is case sensative).

It also support `\citelist`

of amsrefs.

10. Last Words and Feed Back
This document contains the usage of the plugin latex2html, and if you find any errors, or have any suggestions even bugs of the plugin, you can leave a word here, or sent a mail to me: van141.abel(at)gmail.com.

It takes me about one month to write the plugin, I’m too tired to feel glad when I finally finished it. I don’t know whether it will help you a litter to post mathematics with latex language or not, but if it do have any, I will fell much better.

10.1. How to Jump Between Links
If you have just click on a link, then you can go back where you were just by Alt+←

您好，我一直使用您的这个插件，非常好。最近升级时，提示

Parse error: syntax error, unexpected ‘[‘ in D:homechxp1234wwwrootwp-contentpluginslatex2htmllatex2html.php on line 29

请问这个如何解决？非常感谢。

不好意思，刚看到。让主机服务商换成了php5.3,还是不行。有其他办法吗？非常感谢。

暂时没有, 除非修改源码. 关键是即使修改后也不知道还有没有其它不兼容的地方. 故最好的办法就是升级php到最新版.

非常感谢您。实在不行，我换空间。

您好，php升级到5.5，安装还是出现一样的错误，有可能是怎么回事？非常感谢。

这个真不知道了.

ok了，是主机服务商的原因，没有给我开成5.5,默认5.2.麻烦您了。

请问你是从哪个版本升级到哪个版本? 这个错误是由于php有语法错误. 你可以尝试卸载后重新安装最新版. 注意卸载前请备份自己的设置(mathjax+latex命令+bibtex数据)

我重新安装了wordpress，删除所有插件，重新安装latex2html插件，还是报同样的错误。是不是与主机的php版本有关？非常感谢。

请确保WordPress升级到最新版(4.7以上), 这样应该可以排除php版本过低的错误. 此外, 使用插件最新版(2.0.11). 我php版本5.4.17+wordpress4.7.2可以正常运行最新版插件.

wordpress是4.7.2,php版本不确定，我问一下主机服务商。谢谢。

php版本5.1.x，报错是否与这个有关？谢谢。

问题已经确认, 你的php版本太低, php官网说”As of PHP 5.4 you can also use the short array syntax, which replaces array() with []. “故至少要php5.4
