Adding Custom Field to Jobs

1 Is there a place to add Custom Serial Number field separately (Other than Device ID Field. Custom Field Need to input my Own Device ID and Serial Number both in the Job order and Should appear both in the search criterial in Job Listing Page in Admin panel.)?
2. Can we have this custom Device ID as Auto Generated Column by default and Change it manually if needed in the Job Screen?

Please guide how to do this. I have a PHP knowledge.

Can you please attend to this. Client is waiting.

Hey i would not recommend you to do this because this can lead you into problems for future updates however if you want to add custom Field. 

You can do this way. 

Edit file >> computer-repair-shop >> lib >> includes >> wc_jobs.php

Now to display custom field. 

There are two meta boxes Job Details main metabox

Order Informaiton  Sidebar Form

Now decide where you want to add your custom field and add an input field there just like device_id

$content .= '<div class="cell small-6">';
	$content .= '<label>';
	$content .= esc_html__('Device ID/IMEI', 'computer-repair-shop');
	
	$device_id 	= get_post_meta($post->ID, "_device_id", true);

	$content .= '<input type="text" name="device_id" value="'.esc_html($device_id).'" />';
	$content .= '</label>';
	$content .= '</div>'; //Column Ends

You can copy same and just change _device_id and device_id and $device_id to your new field name.  

You can find those lines in this function >> wc_jobs_features_callback

Now to save it. Just go to 

Function  and just add new field name in this array below device_id
