Question

I have a problem to get in a session array from php into a javascript

I´m setting the sessions array here, the print_r is only for checking so it´s correct

  while($row2[]=mysql_fetch_array($result2))
    $_SESSION['row2'] = $row2; 
  print_r($_SESSION['row2'][0][0]);
  print_r($_SESSION['row2'][0][1]);
  print_r($_SESSION['row2'][0][2]);

and in my javascript i use this, alert is only for checking

 var row2 =<?php echo json_encode($_SESSION['row2']) ?>;
 alert (row2[0][0]);
 alert (row2[0][1]);
 alert (row2[0][2]);

row2[0][0] and row2[0][1], works fine, I get the numbers from the array
but row2[0][2] give me the value null, it should be some text in this field, it´s works fine with print_r($_SESSION['row2'][0][2]); in the php-code.

Answer 1

use firebug console or chrome console. After that dump the entire row2 into the console and preview the data.

// JavaScript
var row2 =<?php echo json_encode($_SESSION['row2']) ?>;
console.debug(row2);

Also, keep in mind that all PHP associative arrays will become JSON object and should be accessed with .
