add a the_post hook

[Denis-de-Bernardy]

Could we add a the_post hook, fired when the_post() gets called?

Its absence led me to this bug while investigating a workaround:

It's not clear from your other ticket what you're trying to achieve and how it would be helped by this hook. Please could you supply us with further information.

The purpose was (and still is) to apply filters conditionally on the post.

As a temporary workaround, I end up doing something like this:

on loop start, look at first post. if condition is met, remove all filters on the_content, except the one that checks the next post.

on the_content, look at next post, if condition is met, remove all filters on the_content, except the one that checks the next post, else restore the filters on the_content.

on loop end, restore all filters on the_content.

it's actually not all the filters, but much about. my purpose in doing so is to conditionally disable wpautop, texturize, etc. based on a postmeta's value.

Would a hook be better there or in setup_postdata()?

[Denis-de-Bernardy]

Worth a discussion.

Personally, I use setup_postdata() on singular pages to set a few <meta> tags in my page's header using WP's built-in functions. I might be alone doing this, and would of course fix this accordingly. :-)

Leaving it up to you to decide, as long as the hook is around.

Couldn't that be done by using the_content as an action with higher priority? Something like:

add_filter( 'the_content', 'my_function', 1 );
function my_function( $content ) {
    // add or remove filters for this post...
    return $content;
}

[Denis-de-Bernardy]

not really... foreach makes a copy of the the_content filters before running them, so this would only apply to the next post (see my comment above, it describes just that).

here's another related ticket, that highlights the use for such a hook: #1595

Gigantic +1, I can't believe this isn't already available.
