RE: [PHP] what's "undefined index" ?
Just a follow up - I've been doing some debugging of my own code and here are the three different errors to do with undefined varariables: Undefined variable - variable not set/declared Undefined offset- numeric index doesn't exist Undefined index - alphanumeric index doesn't exist (I may have missed out on one/some) I didn't think about "offset" with I sent my first reply to this thread Hope that helps someone Martin -Original Message- From: Kai Schaetzl [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 26, 2002 11:32 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] what's "undefined index" ?

$KundeRemark = stripslashes($val["KundeRemark"]); ^^^ \ This is fine, you're assigning TO this \ It's this bit that's undefined as you said: > which is a field from a SQL result which currently doesn't exist... so, in a way, you answered your own question.

RE: [PHP] what's "undefined index" ?
Good day, The error message refers to the "KundeRemark" in $val["KundeRemark"], not "$KundeRemark" which you are trying to assign the result to. The former is (if it existed) an index, the latter is a variable.

The most common cause of undefined index is the use of unquoted array keys: $doo = array('dah' => 'dib'); echo $doo[dah]; # incorrect, undefined index error echo $doo['dah']; # correct, no error -- Jason Wong -> Gremlins Associates -> www.gremlins.com.hk /* Life is a game of bridge -- and you've just been finessed. */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

"undefined variable" is when you try to use a variable before you set it, eg $foobar "undefined index" is when you try to reference an array index before you set it, eg $foobar[10] -Original Message- From: Kai Schaetzl [mailto:[EMAIL PROTECTED]] Sent: Monday, March 25, 2002 11:31 AM To: [EMAIL PROTECTED] Subject: [PHP] what's "undefined index" ?
