Before rendering the table, I need the URL parameters (given by the form in the page). But if there are no parameters, we get an error message at the top of the page.
My question is: How can I render the table only if the parameters are in the URL (and therefore not get an error message)?
Hello
Before rendering the table, I need the URL parameters (given by the form in the page). But if there are no parameters, we get an error message at the top of the page.
My question is: How can I render the table only if the parameters are in the URL (and therefore not get an error message)?
I've tried this code, but it doesn't work:
add_filter('wpdatatables_before_get_table_metadata', 'check_wpdatatables_mysql_error');
function check_wpdatatables_mysql_error($table_id) {
if ($table_id == 8 && !isset($_GET['service_depth'])) {
echo 'Error';
return null;
} else {
return $table_id;
}
}
Thanks in advance
