Am trying to upload image using ajax php and jquery what am i doing wrong here. the image should be uploaded without refreshing the page. i have tried the above code. if your see any prolem, help!!
The thing is i want to move the uploaded file to the upload folder and insert the image name to the database as a BLOB.
You can use FormData objects but you need to write the code in plain Javascript because I think JQuery doesn't support it yet. Please read this for more information https://developer.mozilla.org/en-US/docs/Web/API/FormData/Using_FormData_Objects
I am trying to display the onchange value of a textbox using ajax. My code is as follows :
ajaxquery.php
<html>
<head>
<title>Changing textbox value based on dropdown list using Ajax and PHP</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script>
//fuction to return the xml http object
function getXMLHTTP() {
var xmlhttp=false;
try{
xmlhttp=new XMLHttpRequest();
}
catch(e) {
try{
xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e){
try{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e1){
xmlhttp=false;
}
}
}
return xmlhttp;
}
function getCurrencyCode(strURL)

req.onreadystatechange = function()

//when state is completed i.e 4
if (req.readyState == 4)

if (req.status == 200)
{
document.getElementById('cur_code').value=req.responseText;

<body style="font: 12px Verdana, Arial, Helvetica, sans-serif;">
<form style="text-align:center" method="post" action="" name="form1">
<p>Country : <input type="text" name="country" onChange="getCurrencyCode('code.php?country='+this.value)">
</form>
</body>
</html>
code.php
<?php
$country=$_REQUEST['country'];
echo $country;
?>
The value is not displaying. Where am I going wrong?
P.s. I am completely new to ajax and have no knowledge about it. Appreciate any help :)
<p>Country : <input type="text" name="country" onblur="getCurrencyCode('code.php?country='+this.value)">
<p>Country Code : <input type="text" name="cur_code" id='cur_code' ">
Changed the onchange function to onblur and added another input type. It is working perfectly now!
what i intend to do, is to use uploadify to upload a file, change its name in uploadify.php for the value of time() ,save it , and return the name of the saved file back to the HTML, im not sure how to do it, currently im using this as guide

I found the answer to this, after a while of searching and reading uploadify manuals, it turns out if you use onUploadComplete, and you just upload one single fine, the method will never excecute, and it will keep waiting for more files, instead for one file only, you have to use onUploadSuccess, and read the data returned by it using file,data,response as parameters.
I am wanting to have a form that will let me add names to my database without refreshing the form. I have been working on it but it does not seem to work. I am quite new at this so any help is appreciated.
For my index.html I have:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js">
</script>
<script type="text/javascript" >
$(function() {
$(".submit").click(function() {
var name = $("#firstname").val();
var username = $("#lastname").val();
var dataString = 'firstname='+ firstname + 'lastname=' + lastname
if(firstname=='' || lastname=='')
{
$('.success').fadeOut(200).hide();
$('.error').fadeOut(200).show();
}
else
{
$.ajax({
type: "POST",
url: "join.php",
data: dataString,
success: function(){
$('.success').fadeIn(200).show();
$('.error').fadeOut(200).hide();
}
});
}
return false;
});
});
</script>
<body>
<form method="post" name="form">
<ul><li>
<input id="firstname" name="firstname" type="text" />
</li><li>
<input id="lastname" name="lastname" type="text" />
</li></ul>
<div >
<input type="submit" value="Submit" class="submit"/>
<span class="error" style="display:none"> Please Enter Valid Data</span>
<span class="success" style="display:none"> Registration Successfully</span>
</div></form>
For join.php:
<?php
include("db.php");
if($_POST)
{
$firstname=$_POST['firstname'];
$lastname=$_POST['username'];
mysql_query("INSERT INTO persons (firstname,lastname) VALUES('$firstname','$lastname')");
}
?>
and db.php:
<?php
$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "";
$mysql_database = "test";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not connect database");
mysql_select_db($mysql_database, $bd) or die("Could not select database");
?>
there is mistake in code,
you have coded
var name = $("#firstname").val();
var username = $("#lastname").val();
var dataString = 'firstname='+ firstname + 'lastname=' + lastname
you have to used the variables name and username in dataString but you have written the id(s) of fields for first and last name. change either the variable name or variables used in dataString
corrected line is :
var dataString = 'firstname='+ name + 'lastname=' + username
And
$lastname=$_POST['username']; => $lastname=$_POST['lastname'];
after searching the internet I was unable to find an answer as to why my AJAX code is not working. My assignment is to retrieve a text file and display it to the browser using AJAX but the ready state stops at 1. an example file is canada.txt and is located in the directory http://157.201.194.254/~ercanbracks.
