Undefined Index

Recommended Posts

Hello

I have a small problem with a script of mine.. I keep getting an Undefined Index error when I call for a value from an array when that value is not defined. For instance, calling $_REQUEST['do'] when 'do' has no value will return such an error. Is it safe to simply suppress these errors or is there something I should do to eliminate them?

Thanks in advance.

Before you use user defined variables (_POST, _GET, _REQUEST etc). You should check that they exist first. For example:
[code=php:0]if(isset($_REQUEST['do']) || !empty($_REQUEST['do']))
{
    // use $_REQUEST['do']
}[/code]

Doing that will stopo the undefined index notice message appearing.

Or just turn down error_report so it ignores notices
