Why is my if (!in_category) statement not working?

[brightlaunch]

I want to remove the filter amd_zlrecipe_process_head everywhere except from posts in the listed categories... but it doesn't remove it anywhere... what am I missing?

If I just add remove_filter('wp_head', 'amd_zlrecipe_process_head'); then it is removed everywhere - so I know the problem is with the if-statement.

if ( !in_category (array ('11','284','285','288','289','291','292','293','294','295','296','270','273','274','275','279','280','282','283')) ) {
remove_filter('wp_head', 'amd_zlrecipe_process_head');
}

Your if statement needs to be associated with an action or filter. Try something like this instead:

add_action('wp_head', 'custom_show_zlrecipe')

function custom_show_zlrecipe() {

if (!in_category() {

remove_filter('wp_head', 'amd_zlrecipe_process_head');

}

}

That code is untested, so try at your own risk. 🙂

add_action('wp_print_styles', 'custom_show_zlrecipe');
function custom_show_zlrecipe() {
if (!in_category (array ('11','284','285','288','289','291','292','293','294','295','296','270','273','274','275','279','280','282','283'))) {
remove_filter('wp_head', 'amd_zlrecipe_process_head');
}
}


accomplished most of what I needed. But, the scripts still show up on those category pages itself... I only want it to show for the posts in those categories...

Missing a semi-colon at the end of the first line:

add_action('wp_print_styles', 'custom_show_zlrecipe');

Thanks cdils... I realized the missing colon! Just revised my post... it's mostly working, but the scripts still show up on the category pages itself… I only want it to show for the posts in those categories…

You might need to check usage between is_category vs in_category (http://codex.wordpress.org/Conditional_Tags)

For instance,  you don't want it to show if it is_category('category-id) && if it's in_category('post-id').

Ok, I figured it out.... needed || instead of &&:

add_action('wp_print_styles', 'custom_show_zlrecipe');
function custom_show_zlrecipe() {
if (is_category() || !in_category (array ('11','284','285','288','289','291','292','293','294','295','296','270','273','274','275','279','280','282','283'))) {
remove_filter('wp_head', 'amd_zlrecipe_process_head');
}
}
