hooks - Problem in plugin debuging in wordpress

I want to save extra user fields in custom table after user register.

In my plugin I added user_register hook and I am checking this code while user register but I cannot find any errors and cannot print the data.

How can I test this code and what if I want to print something here that will reflect on webpage?

I am new to plugin creation please help you good people.

• I don't think I fully understand your question. Have you read up on how you can test plugins in general? What specific problem is it you're having with your current code? – kero Commented Apr 3, 2019 at 17:37
• Where you have define('user_register ... Do you mean to have, add_action( ... ? – tmdesigned Commented Apr 3, 2019 at 18:01
• I want to call rwdpoint_registration_save function after User register, but can't get in to the function with this hook 'user_register' – Wordpress Learner Commented Apr 3, 2019 at 18:02
• Also, what is $query on your last line? – tmdesigned Commented Apr 3, 2019 at 18:03
• yes please check i edited the line from define('user_register') to add_action('user_register').... it was my mistake – Wordpress Learner Commented Apr 3, 2019 at 18:04

What I do, when I'm developing a plugin (or theme) on a local WordPress install and I'm feeling lazy, I just use a combination of

var_dump($my_variable); 
die; // exit; works too

This way I get an idea whats going on and I see when the variable stops being what I expect it to be.

Another thing I sometimes do is I use error_log( print_r( $my_variable, true ) ); inside functions to push stuff into the error log so that I can review it later.

Unfortunately I haven't worked that much with custom tables so I can't comment on those matters.
