Ajax :: Upload Is Destroying My PHP $_POST?
Aug 26, 2009
I'm using a script I picked up from elsewhere that allows you to do uploading through AJAX (well, actually through an IFRAME,but lets not get into whether that's really AJAX ). Anyway, the script works great except for one little problem though.Sometimes when it submits the ajax form and gets to the server, my $_POST data is empty.The only correlation I've found is I believe it happens when the file I'm uploading is too big (though I'm not exactly sure what the cut off mark is). Regardless, small files aren't causing problems and large ones mean I have no $_POST data on the server when I get there. Here's the script I'm using:
Code:
/**
*
* AJAX IFRAME METHOD (AIM)[code]....
why this might destroy my POST data?

I have found the following code and wish to have it do a POST instead of the GET
ajax.php
<?php
if (is_numeric($_GET['client_id'])) {
include("database.php");
$query="SELECT * FROM `client_addresses` WHERE `client_id` = '". db_input($_GET['client_id']) ."'";
[Code]...

my issue is both a php and a javascript (AJAX) one its one or the other. I have two combo boxes one dependant on the other, populated by AJAX but when I submit the form the secondary combo is not being registered as a php $_POST['var'] in the following action page. The secondary combo is contained and altered using divs and inner.HTML. Is this an expected behaviour or is my issue else where?

This Scripts allows you to upload files using AJAX (I'm not an
expert). The site claims it's the best way to upload files out there,
and the file size is only 1 kb.
I couldn't get it to work for me. I downloaded the files to my
computer, and opened the index file with my browser. It doesn't work
(the demo on their site does); IE doesn't show any error messages or
anything, and FF shows a single word that might be treated as an error
notifier: 'undefined'. Does this thing even work? If it does, could
anyone please give me detailed steps on how to using it on my site?

I've created a PhP page(Main) which will list records and a link to change their "thumbnail". Clicking on it will open a "pop-up" which will present a "File input" box and when user select a file to upload, this popup-page will send the form fields to a "process page" using AJAX. This Process page will upload the file and on success returns nothing else the error to the Ajax object in Popup. On return, the popup page will just reload the thumbnail on main page if success and closes itself.
I'm sure I've described what I wanted to do. Again, in brief: Main->(Opens Popup)->Popup->(Send file using AJAX)->Process Process->(Upload File & return result to)->Popup->(Reload img on Main and closes itself)->Main
Below are my codes:

Does anyone know of an easy to implement ajax upload script for php
which also has a progress bar. If possible I'd like it to be able to
remove already uploaded files and do minor manipulations.

I have a script which allow users to chnage there profile image, and it allmost works perfect. The script is set up so when a user uploads a new picture it overrides the previous one, so if a user have an ID, lets say 15, the image would be called 15.jpg. The problem is that when an new upload is finished it still shows the old image, I think by cache, and thats no good. How do I refresh the image with ajax so when the script has done uploading the image is the new one?
The javascript upload.js:
Code JavaScript:
<!--
function startUpload(){
document.getElementById('f1_userimage').style.visibility = 'hidden';
document.getElementById('f1_upload_process').style.visibility = 'visible';
[Code]....

I need some way to use ajax to upload a file mainly a image and a video to my website.
I googled around and found many people saying it's impossible to do it with ajax.. but there are jquery work around plugins where it uses an hidden ifframe to submit your files.
what is the best and simple way to do this task?

Last year, just a few days before holidays, I wrote a tutorial about a new feature available in Firefox 3 that allows web developers to do AJAX-style file uploads. Initially I intended to publish this tutorial as a SitePoint article, but it got rejected so I published it on my blog.
Now, I'd love some feedback. So, if there's anyone out there that has enough patience to read an exhaustive tutorial about uploading files with nothing more than JavaScript I'd like to hear her/his opinion. If it's crap just tell me 'cause indifference kills. Anyway, if patience is not your strong point there's a ZIP package containing both a "simple" and a "complex" take on the problem. Try those.

I wanted to do an Ajax script to resize and preview and image in an html form. Well, I didn't find how to do with Ajax, so I had to use php.The issue is that JavaScript cannot manage a file field to get the selected file and send it via Ajax. The only way to send a file is submitting a form. To not send all data of the form, the file field must be a separate form from the rest of the data. So it can be automatically sent to a php script, which resizes the image, uploads it and then can display it in a iframe without reloading the page.
Then you have the resized image previewed in the form without submitting all data. And then you can send all data with Ajax, including the path of the previously uploaded image, which is stored as a variable in the iframe.I use one html file and two php scripts, which in total are less than 20 KB.

I'm actually new on jquery ajax. I just wanna ask a little idea about how to create simple file upload (with form) using ajax. I tried using this code:
//form html
<p id="status"></p>
<form id="form1" enctype="multipart/formdata">
<input type="file" id="photo" name="photo" />
<input type="submit" id="save" name="save" value="Upload" />
</form>
//php file
if($_POST){
$name = $_POST['photo']['name'];
$tmp = $_POST['photo']['tmp_name'];
$path = "images/".basename(name);
if(move_uploaded_file($tmp,$path)){
print("Done! File saved...");
}else{
die("Error on uploading!")
}}
//js
$(document).ready(function(){
var photo = $("#photo").val();
$.post("upload.php",{photo:photo},function(data){
$("#status").html(data);
});});

I am trying to implement this jQuery form plugin to do ajax file uploads. Although the documentation is great I am still a little unclear about one thing. Usually when I do ajax submissions I return a response in JSON(using PHP), something like :
<?php
echo json_encode(array("status_message"=>"success"));
?>
When doing some simple tests I have run into a problem and I believe it is due to the way this plugin handles JSON responses. My form :
[Code]...
This does not result in the success event firing but rather the error event. In the plugin documentation it states that it does not handle json responses well and that it recommends wrapping the response in a textarea. Unfortunatly I'm not sure what they mean by that, and what I've tried so far has not worked. ould anyone give me some advice as to how to output the response in JSON properly? Could anyone that has used this plugin for AJAX file uploads offer any advice on doing so?

I'm using AJAX for all the updates to the web site I'm building and it works very well. But now I face the need to:
1) Upload a file (an image or video) to a folder in the server.
2) Insert a row in MySQL with the name of the file plus some other information (year and a comment).
The user would upload the file and fill in the information in the same window, and should have a single message (if possible) saying that the file was added or not (meaning both the upload and the insert).I have been doing some googling and found information as how to simulate and AJAX upload, since it seems AJAX does not support file uploads (hope I'm wrong). This is what I found: [URL]
So following that example I could upload the file, and I'd have all the information from the form, in the PHP, and I could synchronize the upload and the insert, but then I can't figure out how to send the OK from the PHP to a Javascript (i guess) to update the html and display the message in the web site.

I thought this would be straightforward but i can't seem to find out or work out how to access a variable posted via a form on the previous page. I have the following line in some jQuery code:
Code:
$( '#ddlSelectBox > OPTION[value=8]' ).attr('selected', true);
I basically want to check for the value sent via $_POST, then use it to make sure a dropdown is populated with the posted value (in the code above, where "value=8", i need to replace the 8 with whatever value has been posted. I have LiveHTTP headers and can see the value i want being posted as job_id=whatever - i just don't know how to get it
