Experts,

I am trying to create a function which will loop through my DB and pull all of the information for the given querey.  I can confirm that the query below should be pulling two rows of data...but, it only pulls one row.  It is like the while loop is just running once.

Can someone help me make the while loop gather all rows of data?
function get_rows(){
	$nuid = $_GET['nuid'];
	$man_report_sql = "SELECT * FROM schedule WHERE ManagerNUID='".$nuid."'";
	$man_report_query = mysql_query($man_report_sql);
	while($result = mysql_fetch_array($man_report_query)){
		if($result['showed']=='1'){$showed='Yes';}
		if($result['showed']=='0'){$showed='No';}
		$tbl = '
		<tr align="center">
		<td style="background-color:#efffde;">'.$result['JobAssignDescription'].'</td>
		<td style="background-color:#efffde;">'.$result['UserField13'].'</td>
		<td style="background-color:#efffde;">'.$result['EmpFirstName'].'</td>
		<td style="background-color:#efffde;">'.$result['EmpLastName'].'</td>
		<td style="background-color:#efffde;">
		'.$result['JobStartTime'].' '.$result['StartAMPM'].'<br />'.$result['JobEndTime'].' '.$result['EndAMPM'].'
		</td>		
		<td style="background-color:#efffde;">
		'.$result['expected'].'
		</td>		
		<td style="background-color:#efffde; border-right:2px solid #000000;">
		'.$result['notes'].'
		</td>
		<td style="background-color:#fffeba;">
		'.$result['coding'].'
		</td>
		<td style="background-color:#fffeba;">'.$showed.'</td>
		</tr>';
	}//END WHILE STATEMENT;
	return $tbl;
}//END FUNCTION

$rows = get_rows();

echo $rows;

Because you are over-writing $tbl each time instead of adding to it.   Define $tbl at the top of your function as $tbl = "";  Then where you have "$tbl =" use "$tbl .=" instead so the text will be appended each time.

Hi,

get_rows returns string value of $tbl, which is getting set (or re-set) for every while cycle.  You better do incremental .= instead of =.

Something like
$tbl .= '
      <tr align="center">

Good Luck!
