Could be lots of things, since as others have pointed out we'd like to know what you are seeing. But one guess is that the url you are requesting is not hosted on the same server as the html file. That is, the html page you are one should be on http://localhost/.

When i submit form data was passing at my php page but images index is goes undefined...
change the way you pass data in request
try this
$(document).ready(function(){
$('.postMention').click(function() {
$('textarea.mention').mentionsInput('val', function(text) {
var post_text = text;
if(post_text != '')
{
var formData = new FormData($('.form')[0]);
formData.append('text',encodeURIComponent(post_text));
$.ajax({
url: 'ajax/post.php',
type: 'POST',
data: formData,
success: function (data) {
if(msg.error== 1)
{
alert('Something Went Wrong!');
} else {
$("#post_updates").prepend(msg);
//reset the textarea after successful update
$("textarea.mention").mentionsInput('reset');
}
},
cache: false,
contentType: false,
processData: false
});
} else {
alert("Post cannot be empty!");
}
});
});
and input name
<input id="upload_input" name="upload_input" type="file"/>

PS. Don't forget to create uploads directory here:

I am having some problems with my PHP file. So basically I am working on a project that takes two addresses from the user, then it uses javascript to show their route and once they click submit, I want to pass these two variables to PHP file. I researched a lot and found that I would need AJAX call. The problem I am running into is that AJAX call works perfectly, but when I go to PHP file it throws me an error that variables are not defined. Someone, please explain to me what I am doing wrong here.

I have an example of me passing JS variable to PHP.
JS (url and content are JS variables) :
var data_to_send = {
filepath: ""+url,
filecontent: ""+content
};
jQuery.ajax({
url:"php/dynamic.php",
data: data_to_send,
cache: false,
async: true,
type:'post',
timeout:3000//purely optionnal, check jQuery's Doc to learn more about ajax optionnal parameters/settings
});
In dynamic.php :
<?php
$vars = serialize($_POST); /*easier access*/
$file_path = "../".$vars["filepath"];
$file_content = $var["filecontent"]; /*example of assigning a JS var's value to a PHP var*/
$fh = fopen($file_path, 'w+') or die("could not open file");
fwrite($fh, $file_content."\n");
fclose($fh);
?>
PS: I use jQuery for POST, I dunno the pure javascript way to do the same :/
I have a page that has a form on it, when I click a button on the page it sends 3 variables to a layer(page_ref, template_ref, and box_id) via a javascript call.
Then with ajax I get some content from the mysql db with the variables and insert this into a text area on the layer.
The layer has a save button and when I click that I want to save the content of the textarea back to the db.
I can fill the textarea from the db no problem but am having problems pushing is back to the db.
The problem I have is sending the javascript variables to the ajax update page as they need to be passed to php varriables.
heres what I have
on the main page I call a javascript function
edit_box('show',i,'<? echo $page_ref; ?>','<? echo $template_ref; ?>');
in the layer I have this
<style type="text/css">
#popupbox
{
padding:0;
width: 99%;
height: auto;
margin: 0px auto;
position:absolute;
background: #FBFBF0;
border: solid #000000 2px;
z-index: 9000;
font-family: arial;
visibility: hidden;
}
</style>
<script type="text/javascript" src="http://js.nicedit.com/nicEdit-latest.js"></script>
<script>
//Browser Support Code
function get_edit_content(box_id,page_ref,template_ref)
{
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=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("edit_content").innerHTML=xmlhttp.responseText;
var area1 = new nicEditor({fullPanel : true}).panelInstance("edit_content",{hasPanel : true});
}
}
var queryString = "?box_id=" + box_id + "&page_ref=" + page_ref + "&template_ref=" + template_ref;
xmlhttp.open("GET","get_content.php" + queryString,true);
xmlhttp.send();
}
$("#sub").click( function()
{
$.post( $("#myForm").attr("action"),
$("#myForm :input").serializeArray(),
function(info)
{
$("#result").html(info);
});
clearInput();
});
$("#myForm").submit( function()
{
return false;
});
function clearInput()
{
$("#myForm :input").each( function()
{
$(this).val('');
});
}
function edit_box(showhide,box_id,page_ref,template_ref)
{
if(showhide == "show")
{
get_edit_content(box_id,page_ref,template_ref);
document.getElementById('popupbox').style.visibility="visible";
}
else if(showhide == "hide")
{
document.getElementById('popupbox').style.visibility="hidden";
}
}
</script>
<div id="popupbox">
<form id="myForm" action="update_textarea.php" method="post">
<input type="hidden" name="page_ref" value="<? echo $page_ref; ?>" />
<input type="hidden" name="template_ref" value="<? echo $template_ref; ?>" />
<input type="hidden" name="box_id" value="<? echo $box_id; ?>" />
<textarea name="edit_content" id="edit_content" style="width: 500px; height:500px;"></textarea>
<center>close</center>
<button id="sub">Save</button>
</form>
</div>
then I have get_contents page
<?php
include("connect.php");
$page_ref = $_GET['page_ref'];
$template_ref = $_GET['template_ref'];
$box_id = $_GET['box_id'];
$sql = "SELECT * FROM site_content WHERE page_ref='$page_ref' AND template_ref='$template_ref' AND box_id='$box_id' AND box_type='text'";
$result = mysql_query($sql);
while($row=mysql_fetch_array($result))
{
echo "<p>".$row['content']."</p>";
}
?>
and finally the update_textarea page
<?
include("connect.php");
$page_ref = $_POST['page_ref'];
$template_ref = $_POST['template_ref'];
$box_id = $_POST['box_id'];
$edit_content = $_POST['edit_content'];
if(mysql_query("UPADTE site_content SET content='$edit_content' WHERE page_ref='$page_ref' AND template_ref='$template_ref' AND box_id='$box_id' AND box_type='text'"))
{
echo "Successfully Inserted";
}
else
{
echo "Insertion Failed";
}
?>
I realised that i needed to set the values of the hidden inputs in the ajax call after
document.getElementById("edit_content").innerHTML=xmlhttp.responseText;
by adding
document.getElementById("box_id").value = box_id;
etc
I'm trying to do a function that will show the clock on clicking a button but i can't get the clock to show up. I'm kinda new on this stuff and would really appreciate some help with this and also an explanation to what I've done wrong.
Thanks in advance!

And here is the .PHP code.. (telltimeXML.php)

You have missed to close the ' in date finction in telltimeXML.php file .Replace this :
header('Content-Type: text/xml');
echo "<?xml version=\"1.0\" ?><clock1><timenow>".date('H:i:s)."</timenow></clock1>";
with
header('Content-Type: text/xml');
echo "<?xml version=\"1.0\" ?><clock1><timenow>".date('H:i:s')."</timenow></clock1>";
I think you are missing some parentheses at the end of this line:
http.onreadystatechange = useHttpResponse;
