Set WordPress Permalink Setting When Plugin Activated

Wanted:

I want to set permalink setting to ‘/%category%/%postname%/’ when plugin activated

Known:

• • The code in plugin_folder/admin/fahmi_tutorial_activate_permalinks.php

• • The main plugin file is fahmi_tutorial.php

Question:

How to do it?

Answer:

Create fahmi_tutorial_activate_permalinks.php file inside plugin_folder/admin

Create a function named as fahmi_tutorial_activate_permalinks with content like below:

---

<?php

function fahmi_tutorial_activate_permalinks() {
    global $wp_rewrite;

   
    $wp_rewrite->set_permalink_structure('/%category%/%postname%/');

    flush_rewrite_rules(true);
}


$main_file = dirname(dirname(__FILE__)) . '/fahmi-tutorial.php';
register_activation_hook( $main_file, 'fahmi_tutorial_activate_permalinks' );

---

Explain:

• • $wp_rewrite->set_permalink_structure: this code is use to update options wordpress table, which option_name permalink_structure updated with ‘/%category%/%postname%/’ option value

• • flush_rewrite_rules(true): this code is use to update options wordpress table in rewrite_rules option_name

• • $main_file is required because register_activation_hook() function must be run inside main file of plugin

• • register_activation_hook( $main_file, ‘fahmi_tutorial_activate_permalinks’ ): this code is use to run fahmi_tutorial_activate_permalinks function when plugin activated
