I've done this before but for some reason the parameters are being passed oddly.
I have a javascript function that I've used to pass parameters, I've ran some tests and in the function the variables are correct.
These are just a few snippets of the js that relate to the issue:
var tdes = document.getElementById("taskDescription1").value;
var tnam = document.getElementById("taskName1").value;
var shif = document.getElementById("shift1").value;
var ttyp = document.getElementById("taskType1").value;
var date = document.getElementById("datepicker").value;
var ooc = document.getElementById("ooc1").value;
var dateSplit = date.split('/');
var deadlineDate = "";
for( var i = 0; i < dateSplit.length; i++){
deadlineDate = deadlineDate + dateSplit[i];
}
xmlhttp.open("GET","subTask.php?q="+ encodeURIComponent(tdes) + "&w=" + encodeURIComponent(tnam) +"&e=" +encodeURIComponent(shif) + "&y=" + encodeURIComponent(ttyp) + "&b=" + encodeURIComponent(deadlineDate) + "&u=" + encodeURIComponent(ooc),true);
I ran a web console and this is what is actually getting passed...
http://***************/****/********/subTask.php?taskName1=test+taskname+works&taskDescription1=test+des&shift1=All&ooc1=Open&taskType1=normal&datepicker=06%2F28%2F2013
I'm not sure what's going on in between the xmlhttp.open and the GET method in php. None of these variables are getting passed.
Why not use jQuery - very straightforward format (I prefer POST...):
$(document).ready(function() {
var tdes = $("#taskDescription1").val();
var tnam = $("#taskName1").val();
var shif = $("#shift1").val();
var ttyp = $("#taskType1").val();
var date = $("#datepicker").val();
var ooc = $("#ooc1").val();
var dateSplit = date.split('/');
var deadlineDate = "";
for( var i = 0; i < dateSplit.length; i++){
deadlineDate = deadlineDate + dateSplit[i];
}
$.ajax({
type: "POST",
url: "subTask.php",
data: "q="+ encodeURIComponent(tdes) + "&w=" + encodeURIComponent(tnam) +"&e=" +encodeURIComponent(shif) + "&y=" + encodeURIComponent(ttyp) + "&b=" + encodeURIComponent(deadlineDate) + "&u=" + encodeURIComponent(ooc),true),
success: function(whatigot) {
alert('Server-side response: ' + whatigot);
} //END success fn
}); //END $.ajax
}); //END document.ready()
Notice how easy the success callback function is to write... anything returned by subTask.php will be available within that function, as seen by the alert() example.
Just remember to include the jQuery library in the <head> tags:
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>
Also, add this line to the top of your subTask.php file, to see what is happening:
<?php
$q = $_POST["q"];
$w = $_POST["w"];
die("Value of Q is: " .$q. " and value of W is: " .$w);
The values of q= and w= will be returned to you in an alert box so that (at least) you can see what values they contained when received by subTask.php
Following script should help:
function ajaxObj( meth, url )
{
var x = false;
if(window.XMLHttpRequest)
x = new XMLHttpRequest();
else if (window.ActiveXObject)
x = new ActiveXObject("Microsoft.XMLHTTP");
x.open( meth, url, true );
x.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
return x;
}
function ajaxReturn(x){
if(x.readyState == 4 && x.status == 200){
return true;
}
}
var ajax = ajaxObj("POST", "subTask.php");
ajax.onreadystatechange = function() {
if(ajaxReturn(ajax) == true) {
console.log( ajax.responseText )
}
}
ajax.send("u="+tdes+"&e="+tnam+ ...... pass all the other 'n' data );
