[SOLVED] Undefined index

[jim.davidson]

I'm using php 5.0 mySql 4.1.21 and dreamweaver 8

 

I'm getting the following errors

 

Undefined index: contact_areacode

Undefined index: contact_phone_prefix

Undefined index: contact_first_name

Undefined index: contact_last_name

 

Here's the section of code

 

$contact_phone = $_POST['contact_areacode'];

  $contact_phone = $contact_phone.'-';

  $contact_phone = $contact_phone.$_POST['contact_phone_prefix'];

  $contact_phone = $contact_phone.'-';

  $contact_phone = $contact_phone.$_POST['contact_phone_last4'];

$contact_name = $_POST['contact_first_name'];

  $contact_name = $contact_name.' ';

  $contact_name = $contact_name.$_POST['contact_last_name']; 

 

Any idea what's wrong with it or what the error means?

[per1os]

The error means that the array indexes 'contact_Areacode' have not beenset/have no value.

 

It is generally good practice to do an isset statement IE:

 

$contact_phone = isset($_POST['contact_areacode'])?$_POST['contact_areacode']:'';

 

Basically if the index contact_areacode in array post isset/has a value than set the variable to that array index if not set the variable to nothing.

 

This will prevent that error.
