WP_Rewrite::set_permalink_structure() WordPress Method

The WP_Rewrite::set_permalink_structure() method sets the permalink structure for the site. This method takes a string as its only parameter. The string should be the desired permalink structure for the site. The structure should include the leading slash, but should not include any trailing slash. For example, to set the permalink structure to "/%year%/%monthnum%/%day%/%postname%/", you would use the following code: $wp_rewrite->set_permalink_structure( '/%year%/%monthnum%/%day%/%postname%/' ); This method should be called before the 'init' action is fired.

WP_Rewrite::set_permalink_structure( string $permalink_structure ) #

	public function set_permalink_structure( $permalink_structure ) {
		if ( $permalink_structure != $this->permalink_structure ) {
			$old_permalink_structure = $this->permalink_structure;
			update_option( 'permalink_structure', $permalink_structure );

			$this->init();

			/**
			 * Fires after the permalink structure is updated.
			 *
			 * @since 2.8.0
			 *
			 * @param string $old_permalink_structure The previous permalink structure.
			 * @param string $permalink_structure     The new permalink structure.

			do_action( 'permalink_structure_changed', $old_permalink_structure, $permalink_structure );
