I’m attempting to get knowledge from my database to export to a XML or CSV File by utilizing a customized question. That is my perform with the question :
<?php
perform get_workhours($ID){
$sql = $wpdb->put together("SELECT worked_hours FROM db_info WHERE job_id = $ID");
$knowledge = $wpdb->question($sql);
if(empty($knowledge)){
return "0";
}else{
return $knowledge;
} ?>
And in my customized export subject i’ve this :
[get_workhours{ID}]
And when I attempt to preview this it provides me the error :
An unknown error occured.
Ideas for a greater thought for this downside are very welcome aswell.
Thanks upfront,
EDIT : I’m utilizing the WP All Export Professional Plugin. When including a subject to export I select the choice : Customized export subject.
