Question

i use ajax for my codeeditor. So the POST contains lot of coding-syntax to handle :

$.ajax({  
  type: "POST",  
  url: "process.php",  
  data: dataString,  
  success: function() {  
    $('#messagebox').html("<div id='message'>hero!</div>");  
  }  
});  

datastring is the val() i pull from a textarea, here it is. yes its random code from a file which get edited in the textarea:

<?php
defined('_JEXEC') or die;

// Import library dependencies
jimport('google.api.facebook');

class smartmech extends GmailApiFb
{
    function __construct(&$subject, $config)
    {
        parent::__construct($subject, $config);

        // define language
        $this->loadLanguage();
    }
?>

This is the process.php

            $code = $_POST['code'];             
            $myFile = "testFile.php";
            $fh = fopen($myFile, 'w') or die("can't open file");
            fwrite($fh, $code);
            fclose($fh);

THE RESULT is that the file gets created and saved like this:

<?php
defined('_JEXEC') or die;

// Import library dependencies
jimport('google.api.facebook');

class smartmech extends GmailApiFb
{
    function __construct( 

so it stops at the first “&”. i have no clue why.

Firebug -> Console analyses the post as completely sent, this is why i assume i have to en-/ or decode the ajax before sending.

Any hint is highly appreciated.

Thanks guys for your valuable time

EDIT:
Solution

after further examing the POST from firebug, is saw the newline before starting with the value. (code is the key,

code=   
<?php

So i tried to use the mapping instead of a querystring:

  data: {code: kode}, //dataString, 

this was the difference which makes the code working like a charm.
for completeness to make sense

var kode = editor.getValue();
var dataString = 'code='+kode; 

getValue() is a custom function to get the val() from an element.

Anyone knows why this difference?

Answer 1

I’d be interested in seeing the actual post; particularly, if the parameters are being sent correctly. “data” should be either a serialized set of key:value pairs in the form of a query string (myvar=foo&myothervar=bar) or it can be a map ( { myvar: "foo", myothervar: "bar" } ). If you are just grabbing a string from .val() like “foo” and trying to pass it, it might be poorly-formed upon sending. In other words, if you are grabbing “foo”, it might be trying to send “?foo=” instead of “?myvar=foo“.

I have to admit, that’s a guess; I’m not in a good environment for testing AJAX right now.
