We ran into problems setting up our services page becuase of some moderately advanced html code we were using. We were using definition lists with classes and ids on them - not all that advanced if you ask me. Anyways, after much digging and reading I came across a plugin that made it work part of the way. Apparently it does work in regular old WordPress but WordPress MU has some extra restrictions. Those restrictions do make sense when you consider it’s multi blog nature and the opportunity for abuse. Well, we’re running the whole deal here so no need for that but rather than just hack away at the core code, I added 2 hooks to the original plugin. Here’s what i did:
First off grab the latest tmve valid elements plugin http://www.engfers.com/plugins/tinymce-valid-elements/
Secondly install it by dropping it into the plugins directory (not mu-plugins) and activating it the blog that you need it in.
Then I added the code below to the bottom of the tinymce_valid_elements.php file. Here’s the 2 blocks of code:
function tmve_add_tags(&$content) {
$elements = tmve_get_element_map();
foreach ( $elements as $element => $attributes ) {
foreach ($attributes as $attrib ) {
if (isset($content[$element])){
$content[$element][$attrib] = array();
} else {
$content += array(
$element => array(
$attrib => array(),
)
);
}
}
}
return $content;
}
add_filter('edit_allowedposttags', 'tmve_add_tags');
The add_filter call makes wordpress run the function when you save the post which is needed in Wordpress MU. It’s a modification to the tmve_mce_valid_elements function.
Then I also added this:
function tmve_add_styles(&$content) {
$content[] = 'display';
return $content;
}
add_filter('safe_style_css', 'tmve_add_styles');
This hook made it possible to add the css display property into style attributes on my html. We needed this for the bottom part of our services page where we have some content blocks closed when the page loads.
One last thing is to configure it all. Click on Manage > TinyMCE Valid Elements and add the tags / elements you want to support.
Thanks again to David Engfer for the great plugin.
Lastly, I only used this on one blog so I believe you would need to activate and configure in each blog you want to use it in. Does anyone know the detail on that?
in the near future.
