Writing $wp_rewrite->non_wp_rules to .htaccess?

I wonder if I should take the rewrite functionality out of the theme and build it ito an acompanying plugin? I’d prefer to keep it all in the theme though…

Testing… is this thing on? ??

Hi TunaMaxx, have you been able to solve the problem? I’ve got a similar issue, really don’t wanna dig into the admin panel code to see what happens..

No, unfortunately I have not been able to solve it. I did dig into the code a little bit, and from what I can figure out, the key is in the:

$wp_rewrite->flush_rules()

It is supposed to write out the changes to .htaccess if the first arg is NOT set to false.

Hmm… can’t edit my own post to add this, so I thought I’d point out some interesting links. I still haven’t found a solution, but these have shed some light:

Adding rewrite rules and $wp_rewrite->flush_rules():

"This is a bug in the way we store rewrite_rules in "transients"
instead of options like we used to. I think our fix for WP 2.9 is
going to be to revert to the old method.

Correct usage of add_rewrite in plugin:

"Second, the problem is that add_rewrite_rule needs to come before
you flush the rules. I know it seems unintuitive, but what happens
when you flush the rules is that they're immediately regenerated,
at which point WordPress says, "hmm, what rewrite rules do I need
to include?"

I found something more.. flush_rules has $hard = true by default, that means that it is supposed to write to .htaccess, but it doesn’t because the save_mod_rewrite_rules function doesn’t exist at that moment. I tried including both wp-admin/includes/misc.php and wp-admin/includes/file.php and it seems to be trying to write something, but with no success ?? heh.. Let me know if you get to something ..

TunaMaxx, I think I just found a solution … Give me a sec, lemme wrap it up in a post.

Ah, nevermind. Didn’t catch the theme options part. I had to rebuild my .htaccess whenever a page or post is published and flush_rules(true) works fine in publish_post hook …

I’m still scouring code and support forums looking for a solution. Between the two of us, we might just come up with something!

I have been tearing my hair out on this. Is there anyone that can offer assistance? PLEASE?

Success! So simple once you catch on…

The all important $wp_rewrite->flush_rules() can only be called from the Admin side. Makes sense, right? You wouldn’t want to be calling it every single page load.

This whole time, my code has been pretty much correct except for where I was calling the flush. Since it needs to be called from the Admin side, the hook is ‘admin_init‘:

add_action('admin_init', 'ftc_flush_rewrites');

Here is the complete functioning sample code:

function ftc_flush_rewrites() {
 global $wp_rewrite;
 $wp_rewrite->flush_rules();
}

function ftc_add_rewrites() {
 global $wp_rewrite;
 $ftc_new_non_wp_rules = array(
	'find/(this)' => '/addit.php?here=$1',
 );

 $wp_rewrite->non_wp_rules = $ftc_new_non_wp_rules + $wp_rewrite->non_wp_rules;
}

add_action('generate_rewrite_rules', 'ftc_add_rewrites');
add_action('admin_init', 'ftc_flush_rewrites');

Thanks for share =D That worked fine for me!
