[RESOLVED] GD lib / I.E. 6 problem / Maybe Forms also

[severndigital]

I have working code that runs in firefox perfectly fine.

it uses the GD image Library to create some images based off of field the user inputs.

the entire site works in firefox, but when i run the exact same code in Internet Explorer it doesn't work.

does anyone know about any problems with GD and I.E.?

there are 2 steps to the process.

1. An image is created and displayed from a base image file.
2. The user inputs text and clicks update.
3. The script collects the text and applies it to the picture and represents it on screen.

As I said, when I run the script in firefox everything works perfectly.

When I run the script in I.E. it does the following

1. creates an image from the base image file. (leads me to believe GD is working correctly)
2. the user inputs text and clicks update.

it does not appear to be doing step 3.

I do have a form with multiple buttons. Could I.E. be handling that incorrectly?

Any help would be great. I can provide code if needed.

thanks

just to complete this post for future use. I've determined the problem(s)

1. I.E. does NOT like PHP posting of differnt buttons. I resolved this using JavaScript to submit different buttons using different actions.

<SCRIPT>
function submitFunction(i) {
   if (i==1) document.theform.action=
      "www.website.com/script.php?view=8";
   if (i==2) document.theform.action=
      "www.website.com/script.php?view=9";
   if (i==3) document.theform.action=
      "www.website.com/script.php?view=10";
   document.theform.submit()
   }
</SCRIPT>

<!-- Then use this info for your buttons within theform -->

 <INPUT TYPE="button" VALUE="Button 1 onClick="submitFunction(1)">

 <INPUT TYPE="button" VALUE="Button 2 onClick="submitFunction(2)">

 <INPUT TYPE="button" VALUE="Button 3 onClick="submitFunction(3)">

The second problem was a CACHE problem displaying the image that the GD Library re-writes on updating the form.

i resolved this by adding a few parameters to the back end of the image name.

<?
$parameter1 = rand();
$parameter2 = rand();

echo '<img src="nameofimage.jpg?p1=' . $parameter1 . '&p2=' . $parameter2 . '">;
?>

This generates a image file name of

nameofimage.jpg?p1=RANDOMNUMBER&p2=RANDOMNUMBER

This forced I.E. to think that the graphic file is new even though the image is still named the same.

implementing those two solutions has resolved the problems.

hope this (and my countless hours of hair pulling) helps other people in the future.
