[RESOLVED] Different behavior between desktop and BlackBerry

hadoob024

I can't seem to figure this one out. On my site, I have a real estate listing form. One of the fields is for the user to be able to upload a picture. Now, when I access this page on my PC at home, I have no problems. The error handling and security checks work fine. Regardless of whether I input info for this picture field, the form processor works.

However, whenever I try and submit this form using a BlackBerry, I keep getting the following error message:
"Error Message: Undefined index: picture"

And apparently this line of code is the culprit:

if (($_FILES['picture']['size'] != 0) && ($_FILES['picture']['tmp_name'] != ''))

I just can't figure out why this works perfectly on my PC, but causes an error on my BlackBerry. Any thoughts?

I assume that the Undefined Index error is a PHP error?

If so, then I suspect that the Blackberry isn't putting that field into the $_POST string. For example, from the web browser, it forwards the string but the value is null... but from the Blackberry, it doesn't even forward the string.

To try to reproduce the problem on your PC, remove the picture input from the form and submit the page. You should get the same error message.

That's all speculation, though, since I'm still not clear on whether PHP or the Blackberry is the one providing the error message.

This is a PHP warning. You should check if that array index is set at all. Something like

if (isset($_FILES['picture']) && ($_FILES['picture']['size'] != 0) && ($_FILES['picture']['tmp_name'] != ''))

Good call! I think you're right about the BlackBerry not sending it (although I haven't verified it). I took the other suggestion and added (isset($_FILES['picture'])) to my "if" statement, and this solved the problem! Sweet! It works on the BlackBerry now. Thanks everyone!!!
