I'd like to give users the option to change a custom post type slug in my plugin. Using this answer, I'm able to hardcode it into a function:
Redeclare/Change Slug of a Plugin's Custom Post Type
So how can I rewrite this to update when the user updates the plugin option? I tried something like this:
function add_custom_rewrite_rule() {
$slug = get_option('change_rewrite_slug'); // my plugin option
// First, try to load up the rewrite rules. We do this just in case
// the default permalink structure is being used.
if( ($current_rules = get_option('rewrite_rules')) ) {
// Next, iterate through each custom rule adding a new rule
// that replaces 'movies' with 'films' and give it a higher
// priority than the existing rule.
foreach($current_rules as $key => $val) {
if(strpos($key, 'my_post_type') !== false) {
add_rewrite_rule(str_ireplace('my_post_type', $slug, $key), $val, 'top');
} // end if
} // end foreach
} // end if/else
// ...and we flush the rules
flush_rewrite_rules();
} // end add_custom_rewrite_rule
add_action('init', 'add_custom_rewrite_rule');
This doesn't work. I feel like I am missing a step: once the plugin option is saved it needs to tell this function to fire and get the new slug. Or maybe there is a better way to do it.
Also, once it is changed, I need the function to update that, get the current option and then change the slug based on any new input.
The reason I need this is that the plugin has a post type of one kind of event but I want people to be able to customize it so instead of 'event' the slug could be 'show' or 'gig' or whatever they want.
Update: I'm using this class: http://tareq.wedevs.com/2012/06/wordpress-settings-api-php-class/
Here is a section of the options page code:
function flush_settings() {
if( isset( $_REQUEST['settings-updated'] ) )
flush_rewrite_rules();
}
/**
* Returns all the settings fields
*
* @return array settings fields
*/
function get_settings_fields() {
$settings_fields = array(
// Other settings here
'djgigs_basic_settings' => array(
array(
'name' => 'djgigs_rewrite_slug',
'label' => __( 'Permalink Slug', 'wedevs' ),
'desc' => __( 'Enter a custom permalink slug. The default is \'djgig\' but you could change it to \'gigs\' or \'events\'. ', 'wedevs' ),
'type' => 'text',
'default' => 'djgig',
),
)
);
return $settings_fields;
}
Not sure if that is the correct location to add the flush function or if there is something in the Class that is making this not work.
