How to send & as data using _POST method using Ajax

Mar 24th, 2008

Hi All,
I am trying to send some data using Ajax and recieve that data in php code using _POST method.

But my data contains "&" and _POST method takes it as a seperating token and data after tht does not get passed. Does anyone has a solution to this.

Code snippet:

params = "q="+str+"&p="+str1;  //here str1 contains data which has &


  xmlHttp.open("POST",url,false);
  xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
  xmlHttp.send(params);

And on server side when I use
$posted = &$_POST ;

it takes & as a seperator which is present as data.

Please someone let me know the workaround or approach to this.

Thanks John for the input. This what I have done. If one wants to encode and decode the URL in javascript then above reference is fine. In my case i needed to encode at javascript and and decode inside php. The function to be used inside php code is

   preg_replace('/%([0-9a-f]{2})/ie', 'chr(hexdec($1))', (string) $p);

$p is the string which has encoded value. And the first 2 parameters just does enough to decode back whatever [CODE ] encodeURIComponent [/code] has done.

Thanks

just out of curiosity, would str_replace not have worked easier for this?
You have a string (as a variable at least) and you know what other string is inside of it (or could be inside of it), and you know what you want to replace it with.
