How to store default values in add new job fields?

You can do it quite easily with this https://plugins.smyl.es/wp-job-manager-field-editor/

or there are some prefill snippets here https://wpjobmanager.com/customization-snippets/

The prefill snippets will be going directly to my theme’s functions.php? Or into another file?

I have tried the following snippet at the end of my theme’s functions.php file and it doesn’t change anything in the admin side.

add_filter('submit_job_form_fields', 'bk_prefill_jobs_location');
	function bk_prefill_jobs_location( $fields ) {
	  $fields['job']['job_location']['value'] = 'My Custom City Name';
	  return $fields;
	}

Under the Job Listings sidebar item (which appears after installing WP Job Manager Plugin), when a user will click on the Add New sub-menu item for adding a new job, I want this code snippet to prefill the location field for the user. Is this possible with this snippet or am I misunderstanding the purpose of customization through code snippets?

Try using the Code Snippets plugin–I’ve had snippets not work when placed in the functions.php file, but work through the Code Snippets plugin.

I also second @dubaidogfish’s mention of WP Job Manager Field Editor, which is incredibly helpful.

@hazratnoor Do you still need help?

The following solution works for me:

function save_job_meta( $post_id, $post, $update ) {

    $post_type = get_post_type($post_id);
    $meta = get_post_meta( $post_id );
	//var_dump( $post );
    // If this isn't a 'job_listing' post, don't update it.
    if ( "job_listing" != $post_type ) return;
        
	$location = $meta['_job_location'][0];
	$brand = $meta['_business_brand'][0];
    
    if($update){    
	    update_user_meta( get_current_user_id(), '_job_location', $meta['_job_location'][0] );
	    update_user_meta( get_current_user_id(), '_business_brand', $meta['_business_brand'][0] );
	    update_user_meta( get_current_user_id(), '_company_website', $meta['_company_website'][0] );
	    update_user_meta( get_current_user_id(), '_company_name', $meta['_company_name'][0] );
	    update_user_meta( get_current_user_id(), '_company_tagline', $meta['_company_tagline'][0] );
	}
}
add_action( 'save_post', 'save_job_meta', 10, 3 );

My problem is resolved now. The above solution can be used to show those mentioned fields including business brand, company website, job location, company name and company tagline as prefilled for an existing user. If the user has already posted a job in the past, these fields will be shown prefilled.
