Comments on: LatexRender as a plugin

Solved. I modified the plugin to output $status_code to a file and figured out that the actual error was: “I can’t find the format file `latex.fmt’!”. So a simple:

$ texconfig init

From the command line, fixed it.

It looks as if PHP is not allowed to run LaTeX. You need to ensure that PHP is allowed to run the exec command.

I followed the instructions step by step. In the tmp folder, if I comment out the unlinks, I only get a valid .tex file generated. If I manually invoke latex on it, it works as advertised. Any ideas? latex, and all the other executables are in /usr/bin as specified in the php file. I also set the latexrender paths as specified.

What could be the issue?

Almost certainly there is an error in the line in latex.php
$latexrender_path_http = "/latexrender";
You needed to change this to give the path of your pictures.
If you look at the source of the page with broken images you will see what URL img src is using and hence what the error is.

Hello Steve.

I hope I haven’t missed the boat on this one and if I am disturbing you in important work I excuse myself.

I have been trying to install your latexrender plugin for wordpress. It seems to work well until the pictures are about to load on the webpage. All I get are broken images, as in the images files wouldn’t exist.

Of course when I look in my /latexrender/pictures/ folder they are all there.

Is this something you have encountered before?

Thank you very much

Karl

Thanks Steve, I’m not sure why I thought there would be an abs command given that I usually use \left| and \right| myself.

Thanks for writing the plugin

That's because there is no such command as \abs in LaTeX (see The Comprehensive LaTeX Symbol List), so there is nothing wrong with the installation. You could use |x| or \lvert x \rvert to make the || resize with the formula. If you need it often, then you can do what you would do in a document, and add to class.latexrender.php after $string .= "\begin{document}\n"; the line $string .="\\newcommand{\abs}[1]{\lvert#1\rvert}\n"; then you can use \abs{x}.
