I've written the code below to perform the following:
Create a table that has three cells for each row. Each cell has a graphic and a radio button. The first row works fine. It gets to the third cell and starts creating the next row. The second row, however, just keeps creating cell after cell after cell, never getting around to creating the third row.
I have scoured this code for the reason, but I am obviously too close to the problem. Please help!
<?php
// Get the graphics, if any
$queryg = "SELECT * FROM spec_graphics WHERE graph_id >= '2' ORDER BY graph_id";
$resultg = mysql_query($queryg)
or die ("can't execute query. Refresh your browser to try again.");
$graph_num = mysql_num_rows($resultg);
if ($graph_num == "0")
{
// No graphics to display
echo <<<BLIMEY
<table width="100%" border="0" cellspacing="0" cellpadding="2">
<tr align="center">
<td width="99%" height="50" class="back"><b>Delete a Graphic:<br />
At this time you have no uploaded custom graphics to delete</b></td>
</tr>
<tr align="center" valign="middle">
<td class="back"><img src="images/grey-span.gif" width="100%" height="3" /></td>
</tr>
</table>
BLIMEY;
}
else
{
// There is at least one graphic to display
echo <<<THEBEGIN

}
?>
There is obviously more to the code, but everything else works fine. It's just that darned second row!
