 * I’ve been banging my head on the desk for a while over this. Seems like it should
   be pretty simple but… not working. Trying to simply return an array from a function.
 * I have a grid showing database results. If any are in error, there should be 
   notifications as such above the grid.
    -I call a function which checks the results
   for errors, and counts them. Within this function, another function is called
   to display the notification indicating the quantity of errors. This works properly.
 * -These notification also provides a link to view the database record in question–
   primary key ‘id’ is returned in an array from the function. However, the array
   that I am returning that should contain the ‘id’ of the erroneous record comes
   out of the function empty. If I var_dump within the function, the array contains
   the records I would expect it to.
 * The code for the main page flows like this (code is abbreviated):
 *     ```
       include 'header.php'
       include 'error_check.php' (file containing the error check function)
       include 'notices.php' (file containing the function to display notices)
       check_for_errors($qdate, $salesman_id);
       if($_REQUEST['view'] = 'nomatch' { include 'nomatch_grid.php' }
       if($_REQUEST['view'] = 'unknown' { include 'unknown_grid.php' }
       if(!$_REQUEST['view'] { include 'main_grid.php' }
       ```
   
 * Here is the code for the check_for_errors() function:
 *     ```
       function check_for_errors($cfe_date, $salesman_id) {
       	global $wpdb;
   
       	$d_year = date('Y', $cfe_date);
       	$d_month = date('m', $cfe_date);
   
       	$spiffs = $wpdb->get_results("SELECT * FROM spiff_records LEFT JOIN spiff_items ON spiff_records.item = spiff_items.item_number WHERE YEAR(inv_date) = $d_year AND MONTH(inv_date) = $d_month AND salesman_id = $salesman_id ORDER BY inv_date ASC");
   
       	/**
       	* RUN THROUGH ALL SPIFFS RETURNED IN MAIN QUERY
       	* ASSIGN COUNT OF HOW MANY RECORDS DONT MATCH AN ITEM
       	* CREATE ARRAY CONTAINING <code>SPIFF_ID</code> WITH ITEMS THAT DON'T MATCH
       	**/
       	$nomatchct = 0;
       	$nmarray = array();
       	foreach($spiffs as $nomatch) {
       		if(!$nomatch->item_number && $nomatch->unknown != 1) {
       			$nomatchct = $nomatchct + 1;
       			$nmarray[] = (string)$nomatch->spiff_id;
       		}
       	}
   
       	/**
       	* RUN THROUGH ALL SPIFFS RETURNED IN MAIN QUERY
       	* ASSIGN COUNT OF OUT HOW MANY ARE MARKED AS UNKNOWN BY ADMIN
       	* CREATE ARRAY CONTAINING <code>SPIFF_ID</code> WITH RECORDS MARKED AS UNKNOWN
       	**/
       	$unknownct = 0;
       	foreach($spiffs as $unknown) {
       		if($unknown->unknown == 1) {
       			$unknownct = $unknownct + 1;
       			$ukarray[] = (string)$unknown->spiff_id;
       		}
       	}
   
       	display_notices($unknownct, $nomatchct);
       	return $ukarray;
       }
       ```
   
 * Finally, here is the link for the display_notices() function:
 *     ```
       function display_notices($unknownct, $nomatchct) {
       	if($unknownct > 0) {
       		echo '<div class="notice red">';
       			echo '<p><strong>NOTICE:</strong> You have ' .$unknownct. ' records with unknown item numbers.  <a href="/view/?view=unknown">Click here to review these entries.</a></p>';
       		echo '</div>';
       	}
   
       	if($nomatchct > 0) {
       		echo '<div class="notice green">';
       			echo '<p><strong>NOTICE:</strong> You have ' .$nomatchct. ' records waiting to be reviewed.  <a href="/view/?view=nomatch">Click here to review these entries.</a></p>';
       		echo '</div>';
       	}
       }
       ```
   
 * Since I am using includes, the check_for_errors() is run no matter which grid
   we are looking at, so if I return the $ukarray or the $nmarray, I should be able
   to use those arrays in order to display the records who’s ID is in that array.
   Or So I thought.
 * If anyone has time to check this out and let me know what they think I’d greatly
   appreciate it!!

 * Have you tried `$ukerrors = check_for_errors($qdate, $salesman_id);`?
