[mapguide-users] PHP script for getting data from selected item(s)

[Andrew DeMerchant]

That's out of my league too.....glad to see that this script is getting 
added to the toolset! And glad to see that it will get some use...I 
actually have since modified the original script slightly....I changed 
the lines:

echo 
'<pre>'.$ReportURL."?".$DestinationKeyName."=".$val."&".$AdditionalData.'</pre>';
header("Location: 
".$ReportURL."?".$DestinationKeyName."=".$val."&".$AdditionalData);

to :

echo '<META HTTP-EQUIV="Refresh" Content="0; URL=' . $ReportURL . "?" . 
$QueryString . $AdditionalData . '">';

I did this because in my case, I wanted to be able to resize the window 
that the ReportURL was taking the user to (based on a height / width 
variable passed in AdditionalData. And it seemed as though the header 
forwarding method was not letting that happen.....the meta method works 
well for this.
