How do you prevent the WordPress editor from stripping out certain HTML tags

looking for a non-hacky, non disaple the visual editor, non use this plugin answer.

Never switch between the two. However, and for protecting at least a set of links I want to always remain formatted in my own way at the bottoms of pages I have made a php file called from the page template in this kind of way:

<div class="entry-content">
	<?php the_content();?>
	<?php get_template_part('links','bottoms');?>
	<?php wp_link_pages(array('before' => '<div class="page-links">' . __('Pages:','twentytwelve'),'after' => '</div>'));?>
</div><!-- entry-content -->

Declaring there is “no use case” to support switching between visual and text mode does not fit the real world.

Certainly not everyone’s as far as actual usage is concerned, and there is where various plugins and such can come into play for many even if not for all. For some, the user profile’s “Disable the visual editor when writing” option protects HTML work from being modified, and I mention that not to argue but just to point out that the devs are aware and do care. But since WordPress is not a commercial venture hoping to be everything for everyone and while including the devs as end users, we have what we have until the same or even more volunteer devs perceive a sufficient need or desire or whatever and then (or even simultaneously) assess the matter of the work required for all to have it.

It’s really annoying but you have to make sure you stay in the code view and not save when you are in visual mode. I wish there was a code cleanup option we could just turn off if we liked.

So they can’t just put an option in the settings to disable the code cleanup? That makes no sense. WordPress is no longer a simpleton’s platform.

i just read somewhere from a WP techie that the problem is TinyMCE’s cleanup function, upstream from WP; i distinctly remember a plugin that did it for me a couple of years ago, though.

they seem to be fairly sparse these days. it’s sure pissing me off though, it adding <p></p> where it wants to if i try to paragraph my own text.

kind of like the (current) US Government. knows what’s better for us than we do…

Just use this. Put it in functions.php.

You can add more of your own html tags.

// Prevent TinyMCE from stripping out html
function schema_TinyMCE_init($in)
{
    /**
     *   Edit extended_valid_elements as needed. For syntax, see
     *   http://www.tinymce.com/wiki.php/Configuration:valid_elements
     *
     *   NOTE: Adding an element to extended_valid_elements will cause TinyMCE to ignore
     *   default attributes for that element.
     *   Eg. a[title] would remove href unless included in new rule: a[title|href]
     */
    if(!empty($in['extended_valid_elements']))
        $in['extended_valid_elements'] .= ',';

    $in['extended_valid_elements'] .= '@[id|class|style|title|itemscope|itemtype|itemprop|datetime|rel],div,dl,ul,ol,dt,dd,li,span,a|rev|charset|href|lang|tabindex|accesskey|type|name|href|target|title|class|onfocus|onblur]';

    return $in;
}
add_filter('tiny_mce_before_init', 'schema_TinyMCE_init' );
