Hello,

I am working on blogging using org2blog, allowing me to update my
wordpress blog with org-mode. All is working well except latex. I was
expecting latex images but instead just get things like:

$latex z * k^\theta$

The header to my blogpost.org file has

#+DESCRIPTION:
#+KEYWORDS:
#+LANGUAGE:  en
#+OPTIONS:   H:3 num:t toc:t \n:nil @:t ::t |:t ^:t -:t f:t *:t <:t
#+OPTIONS:   TeX:t LaTeX:t skip:nil d:nil todo:t pri:nil tags:not-in-toc
#+INFOJS_OPT: view:nil toc:nil ltoc:t mouse:underline buttons:0
path:http://orgmode.org/org-info.js
#+EXPORT_SELECT_TAGS: export
#+EXPORT_EXCLUDE_TAGS: noexport
#+LINK_UP:
#+LINK_HOME:
#+XSLT:

Am I doing something wrong?

Thanks,
Stephen

Not sure what that latex is doing in there. The following works as normal
HTML for me:

--8<---------------cut here---------------start------------->8---
* foo
Here's a formula


$\int_0^\infty e^{-x^2} dx = {{\sqrt{\pi}}\over{2}}$

$latex z * k^\theta$
--8<---------------cut here---------------end--------------->8---

A few things: the default way to export fragments is through MathJax:
there may be some sort of a setup problem that prevents MathJax from
working with the blogging stuff.  You might want to fall back to
png images and see if that works better for you (you'll need dvipng),
although that's usually seen as a step back.

The preferred way to enter math in latex (and in org) is with \(...\)
for inline formulas and \[...\] for displayed ones. $...$ will work with
certain restrictions noted in the org docs (see below) for the inline
case, $$...$$ does *not* work for the displayed case (it's not even legal
LaTeX).

C-h v org-export-with-LaTeX-fragments RET has the details.

(info "(org) LaTeX fragments") has more on $...$, mathJax etc.

I don't use org2blog myself. But I see org2blog parse org entry to wordpress
post.

(setq org2blog/wp-latex-to-wp nil)

if you put above may stop org2blog parse the latex bits. However original
author Puneeth will have better answers.

I'd like to clarify that the initial implementation of org2blog, IIRC,
did make use of the png images and upload them to the blog.  Sometime,
later support was added to support Wordpress's LaTeX plugin. To render
your LaTeX using this, in your wordpress blog, just set the variable
`org2blog/wp-use-wp-latex`.  [Btw, I hope you are indeed talking about
org to wordpress org2blog. There's another one that publishes to
blogspot, with the same name.]

Also, all of these ways which do work with HTML export should work
with the org2blog.  Also, thanks Nick for the detailed answer. :)

HTH,
Puneeth

Thanks for the help. I just checked the variables and
org2blog/wp-use-wp-latex was set, but the wp-latex plugin was not
installed :) All is working now, although it is definitely a little
grainy. But, it'll certainly lead to an awesome series of blog posts
nonetheless. Puneeth, thank you so much for the fantastic plugin.

One other quick question: Does org-mode and org2blog work with
numbered equations and equation references? If so, could someone
provide a simple example?

Thanks,
Stephen
