Passing variables through php and jquery in wordpress

Question

I am using wordpress and have the following code on functions.php file

function fun1() {
 wp_enqueue_script( 'aldi_code', 'wp-content/uploads/custom-css-js/675.js', array( 'jquery' ), false, true );

 wp_localize_script( 'aldi_code', 'test', array(
     'current_user' => wp_get_current_user()
 ) ) ;
} 
add_action( 'wp_enqueue_scripts', 'fun1' );

I want to access the value of current_user from wp_admin through jquery using the following code

jQuery(document).ready(function( $ ){
    
    var displayName = test.current_user.display_name;       
});

The problem is that I get the error:

test is not defined.

Do you have any idea what is wrong on this code??

Is the document.ready function inside the wp-content/uploads/custom-css-js/675.js file? — Kinglish

The 675.js file has only the this code jQuery(document).ready(function( $ ){ var displayName = test.current_user.display_name; }); — Alduxo

Based on how you're passing the current_user object to the jQuery. Your jQuery should look like this to get display_name.

To see what is passed to current_user in the JS. Just go to the developer's console and type in test.current_user and you'll see that data is where the userdata is stored as an object.

You also don't need to use document(ready) - for whatever that's worth.

jQuery(
    function($){
        let display_name = test.current_user.data.display_name;
    }
);

If you don't wanna pass values between JS and PHP directly, you can use cookies. Both of them can read and write data in there. Set a cookie in PHP, then read it in JS.
