Question

I just installed LAMP. Everything seems to be working fine except when I send data from js to php via ajax, php does not receive the data sent. I suspect this has to do with a setting in php.ini but I don’t know which to change. My js ajax function looks like this:

function ajax (url, data_to_be_sent, callback_func) {

if (window.XMLHttpRequest)

{// code for IE7+, Firefox, Chrome, Opera, Safari

    xmlhttp=new XMLHttpRequest();

}

else

{// code for IE6, IE5

    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

}

xmlhttp.onreadystatechange=callback_func;

xmlhttp.open("POST",url,true);

xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");

xmlhttp.send(data_to_be_sent);

}

Two things you need to do:

1. Debug your client side Javascript to verify you’re making the right call, with the right URL string.

2. Look at your server side logs to see if any client-side requests are being made, and if there are any errors.

This really has nothing to do with PHP, and messing with php.ini isn’t going to help.

PS:
You’re using something like Firebug, aren’t you?
