I have a gateway plugin and I added the code below to redirect the customer to a custom page when the payment fails.

My question is, do I need to add exit(); after the end of the redirect_url which is inside the if statement?

I have seen some codes with exit and some without.

else {
        //failed
        $this->msg['class'] = 'error';
        $this->msg['message'] = __( "Your Transaction Has Failed Due to Some Technical Error. Please Try Again.<br/><br/>", 'toBeTranslatd');
        $order->update_status('failed');
        $order->add_order_note('Failed');
        $order->add_order_note($this->msg['message']);
        $redirect_url = home_url( '/payment-faild/' );

        $lang_code = get_post_meta( $order_id, 'wpml_language', true );
        if ( $lang_code === ar ) {
            $redirect_url = apply_filters( 'wpml_permalink', $redirect_url, $lang_code );
            //exit(); // Do I need this or delete it?
        }
}

Wordpress provides two functions for this:

• wp_redirect^Doc

and

• wp_safe_redirect^Doc

And here's what wordpress recommends:

Note: wp_redirect() and wp_safe_redirect() do not exit automatically, and should almost always be followed by a call to exit;

CodePudding user response：

wp_redirect() or wp_safe_redirect() does not exit or die automatically, and should almost always be followed by a call to exit or die();
