Fatal error: Uncaught Error: Call to undefined function do_action_ref_array() when using wp_signon function

Question

I am newbee to web development,since last few days i am struggling to login through php code. My PHP code is as follow

//my php code @include_once '../wp-includes/user.php'; $creds = array( 'user_login' => 'abc', 'user_password' => 'abc', 'rememember' => false ); $user = wp_signon( $creds, 0 ); if ( is_wp_error($user) ) echo $user->get_error_message(); 

when the PHP code is executed on server i get the below error.

Fatal error: Uncaught Error: Call to undefined function do_action_ref_array() in /Users/meenalgupta/Sites/wordpress/mysite/wp-includes/user.php:57 Stack trace: #0 /Users/meenalgupta/Sites/wordPress/mysite/wp-admin/mypage.php(38): wp_signon(Array, 0) #1 {main} thrown in /Users/meenalgupta/Sites/wordpress/mysite/wp-includes/user.php on line 57

My wordpress version is 4.4.1.

Please let me know what to do?

Answer 1

You should BIND the codes into action (you can use plugins_loaded for earliest stage):

add_action('plugins_loaded', 'my_func'); function my_func(){ // ======== HERE YOUR CODES =========// } 

p.s. you have to include the file correctly!

include_once(ABSPATH.'wp-includes/user.php'); 

Answer 2

You probably call wp_signon too early. You first need to let all of the wordpress core to load before calling it
