Undefined index: inputValue

[Ribster]

These are the first 4 lines of my page:
[php]
<?php
//Receive passed value from self - if null must be first visit so reset to 0

$PassedID = $_GET['inputValue'];
[/php]
The fourth line causes the problem of an undefined index for inputValue.

The first time the page is open nothing is passed in the address line.

Could someone help.

Thanks.

Welcome Ribster to TSDN!

Problem is that entry inputValue does not exist in the $_GET array.
Maybe you misspelled the entry name or it is in nthe $_POST array.

If none of this is the case, maybe you should show your code so we can look at the cause of this.

Next time enclose any code within the proper code tags. See the Posting Guidelines on how to do that.

Thank you for that.

This is the problem:

Problem is that entry inputValue does not exist in the $_GET array.

What code can I use to in an If statement to check for this?

Thanks,

I've found the answer

if (! isset($_GET['inputValue'])){
$PassedID = 0;
}
else {
$PassedID = $_GET['inputValue'];
}
