So I'm passing an array to my javascript via php via ajax.

Here is the array that's been passed in.

PHP:
Code:
Array (     [0] => Array         (             [ConsultantID] => 2             [ConsultantIN] => GAW             [Login] => GAW002             [Consultant] => Gene Williams             [SecurityLevel] => 1             [Extension] => 0             [UserName] => gwilliams             [Password] => blah             [Address] => 123 Blah Ln             [City] => Fort Worth             [State] => TX             [ZipCode] => 76108             [Email] => blah@blah.com         )  )


when i access

Javascript:
Code:
array[0]['Consultant']


it says undefined.


EDIT: I accidentaly put a dollar sign in front of array[0]['Consultant'] when I orignally wrote this effectivley making it php code but it was actually javascript.

what have I done wrong?
How can i export an array from php to javascript better?

Code:
<?php
$array = array ( "0" => array ( "ConsultantID" => 2,  "ConsultantIN" => "GAW" , "Login" => "GAW002",  "Consultant" => "Gene Williams" , "SecurityLevel" => 1 , "Extension" => 0 , "UserName" => "gwilliams",  "Password" => blah , "Address" => "123 Blah Ln" , "City" => "Fort Worth" , "State" => "TX",  "ZipCode" => 76108 , "Email" => "blah@blah.com" ) ) ;

echo $array[0]["Consultant"];

?>

That didn't help at all.

Have you tried just echoing the php on the page instead of javascript to make sure that it's defined? Try echoing parts of the array on the page as raw text, or even do a print_r of the whole array to make sure all entries are defined. If they are, then it's a problem with your javascript. I would also make sure that you have single quotes around each key string.

(Assuming I have the order right... Ajax -> Php -> JS?)
[OOC: I believe this is in the wrong board as well :O]

You said that you're passing an array from php to javascript but I don't see javascript at all. $array[0]['Consultant'] is definitely a PHP construct. What ajax method/framework do you use?

I also find firebug (a firefox extension) to be very helpful in developing ajax apps. In particular you can take a peek of any data transferred through xmlhttprequest in firebug.

I'm not using a framework, I read I need to serialize the array in php and use a php unserialize function in javascript.

I echoed the php via print_r already and I get the desired array.

As far as I know ajax is just javascript using data that is usually retrieved using the XMLHttpRequest object.

Make sure all your strings are in single quotes. I saw some discrepancy there between your array and your echo. (the keys)

So you are saying I should be using XML or JSON to xfer data from php to ajax instead of just echoing plain text? Smile

EDIT: Thank you, JSON is AWESOME!!
