Right, the first field you need to edit is
includes/forms/class-wp-job-manager-form-submit-job.php
Around line 100 you need to add an array similar to the following (Use the other arrays on the file to give you an idea)
'application_deadline' => array(
'label' => __( 'Application Deadline', 'job_manager' ),
'type' => 'text',
'required' => true,
'placeholder' => '',
'priority' => 7
),
Make sure you have a different priority to the others.
Then around line 435 you need to add a line to put the form input into the database.
Add something like this:
update_post_meta( self::$job_id, '_application_deadline', $values['job']['application_deadline'] );
That should handle the adding the entry to the database side of things.
Now to add the function to get the element from the database.
Open up the file wp-job-manager-template.php
You can add this function to the bottom of the file:
/**
* Display or retrieve the current application deadline with optional content.
*
* @access public
* @param mixed $id (default: null)
* @return void
*/
function the_application_deadline( $before = '', $after = '', $echo = true, $post = null ) {
$application_deadline = get_the_application_deadline( $post );
if ( strlen( $application_deadline ) == 0 )
return;
$application_deadline = esc_attr( strip_tags( $application_deadline ) );
if ( $echo )
echo $application_deadline;
else
return $application_deadline;
}
/**
* get_the_application_deadline function.
*
* @access public
* @param int $post (default: 0)
* @return void
*/
function get_the_application_deadline( $post = null ) {
$post = get_post( $post );
if ( $post->post_type !== 'job_listing' )
return;
$application_deadline = $post->_application_deadline;
if ( strlen( $application_deadline ) == 0 )
return;
if ( strpos( $application_deadline, '' ) === 0 )
$application_deadline = substr( $application_deadline, 1 );
return apply_filters( 'the_application_deadline', $application_deadline, $post );
}
Now you should just be able to add <?php the_application_deadline(); ?>
to bring up the application deadline.
Just an advisory, I’m not a professional developer. You should look over my code, as I’ve mainly looked over current code and replicated it with minor changes.
