this is row 232

  $output_rows[$row] .= "<td width=150 >$suburb</td>"; 

this is the code.

<?
$sql_suburb = "SELECT suburb_name FROM suburbs_home ORDER BY suburb_name"; 
$sql_result_suburb = mysql_query($sql_suburb,$connection) or die ("Could not connect to database 2"); ?>

<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td>
 <?  

$num_rows = 15; 
$row = 0;   

while ($line_suburb = mysql_fetch_array($sql_result_suburb, MYSQL_ASSOC)) {
   $suburb = $line_suburb["suburb_name"]; 
   $row++; 
   if ($row > $num_rows) {   

      $row = 1; 
   } 
   $output_rows[$row] .= "<td width=150 >$suburb</td>"; 
}   

echo "<table>"; 
for($i=1; $i<=$num_rows; $i++) { 
   echo "<tr>" . $output_rows[$i] . "</tr>"; 
} 
echo "</table>";  

?> 
    </td>
  </tr>
</table>

open your php.ini file and change the error reporting settings from

error_reporting = E_ALL

to

error_reporting = E_ALL & ~E_NOTICE

[aron]

im not allowed to edit the php.ini file is there another way.

the site is hosted on a proper hosting plan.

cheers aron.

[sid]

hmmm - you should try emailing your provider - maybe they upgraded php and simply forgot to edit the setting... you also could try to override it locally:

ini_set("error_reporting", "E_ALL & ~E_NOTICE");

[aron]

cheers all good.

[sid]

im glad i could help!

You could also create $output_rows before you try to use it...

$output_rows = array();
while ($line_suburb = mysql_fetch_array($sql_result_suburb, MYSQL_ASSOC)) {
   $suburb = $line_suburb["suburb_name"];
...
if(!isset($output_rows[$row]))
    $output_rows[$row]='';
$output_rows[$row] .= "<td width=150 >$suburb</td>";  

 

If you want to hide error messages from yourself you can also use [man]error_reporting[/man]

Actually, aron, I would suggest leaving error_reporting at E_ALL
Notices generally arent all that important, true, but you might as well ensure that they are fixed to avoid potential problems.

When you wish to go into production stage, just set display_errors in php.ini to Off, perhaps by requesting the change from your hosting provider.

Exactly; who knows what else you might be missing?
