i just came across this ajax upload plugin and i wish to use it inside a form as shown in the demo page example 3. For some reason i am not able to make it work. I am not sure what parameters come into the function. For example here is my sample code.
$(document).ready(function(){
var upload = new AjaxUpload('property_i',
{
action: 'submitproperty.php',
autoSubmit: false,
onSubmit : function(file , extension){
return false;
}
});
var upload_data = upload.setData({
'propertytype':'propertytype'
});
});
Now the ID used in the AjaxUpload function should be ID of the or of the Entire form. Also how do i use setData method. Any suggestions or links will be very helpful. Thanks
I got it to work with the following code:
new AjaxUpload('#uploader_button', {
action: 'filename.ashx',
autoSubmit: true,
onSubmit: function(file, ext) {
// --- stuff here
// --- add postdata parameters
this.setData({ id: 1, title: docTitle.val() });
},
onComplete: function(file, response) {
// --- stuff here too
}
});
it doesn't utilize the var but instead adds the custom data params in the onSubmit block. The only other difference is that I haven't wrapped the parameter key in quotes as it seems to serialize correctly. And I'm not using autoSubmit: false , but instead it's true...
The only way I could get this to work with autoSubmit: false is to add this outside any function:
var uploader;
var uploadFile;
then in the AjaxUpload(...
onChange: function(file, response){
uploader = this;
uploadFile = file;
},
then in the function to do the upload:
uploader.setData({session: session});
uploader.submit();
Hope this helps

My current code is:
var CommissionLogs = $("#CommissionLogs").DataTable({
ajax: {
url: ajaxurl + '?action=pos&post_action=get_commissions'
},
'initComplete': function (settings, json){
//possible to access 'this'
this.api().columns(1);
}
});
I improved the code above as below with help :
var CommissionLogs = $("#CommissionLogs").DataTable({
ajax: {
url: ajaxurl + '?action=pos&post_action=get_commissions'
},
'initComplete': function(settings, json){
callbackFunction(settings);
}
});
function callbackFunction(settings){
var api = new $.fn.dataTable.Api( settings );
// api is accessible here.
}
Update :
Now I can access api from callback function. But I want use same callback with load() as below code.
CommissionLogs.ajax.url( newAjaxURL ).load( callbackFunction(), true);
But settings param is not accessible in load function.
I can clear and destroy datatable and re initialize always. But what will be the right way.
I think you need settings:
https://datatables.net/reference/type/DataTables.Settings
$('#example').dataTable( {
"initComplete": function(settings, json) {
myFunction(settings);
}
});
function myFunction(settings){
var api = new $.fn.dataTable.Api( settings );
// Output the data for the visible rows to the browser's console
// You might do something more useful with it!
console.log( api.rows( {page:'current'} ).data() );
}
Other option is re-use your var CommissionLogs variable throughout the code without using this, I recommend strongly this last option.
The dataTable.ajax.url().load() has not access to settings.
So can not call a callback function with settings.
But possible to use callback function without settings.
So here is an alternative way to use settings.
CommissionLogs.clear();// clear the table
CommissionLogs.destroy();// destroy the table
CommissionLogs = $("#CommissionLogs").DataTable({
ajax: {
url: newAjaxUrl
},
'initComplete': function (settings, json){
callbackDatatableFunciton(settings);
}
});
I am a newbie in magento and trying to implement ajax,but can't find a proper tutorial to follow. Could anyone provide me some reference or guide me to where i would be able to find it?
Don't know a tutotial but I can explain you bit what I implemented in a project a month back.
I created a controller on which we can fire an AJAX request on a specific action. In this case the getoptionsAction in the IndexController of our custom Offerte module.
The getoptionsAction in my controller takes a product_id and loads the options for the product. It builds the HTML and echo's this on function end.
In phtml file I have following code to invoke the AJAX request and update html-object in frontend:
function get_options(prod_id){
var product_options = $('product_options');
var prod_id = $('product').getValue();
new Ajax.Updater('product_options',
'<?php echo Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_WEB); ?>offerte/index/getoptions',
{ method: 'get',parameters: {prod_id: prod_id, type: 'get_regular_options' } ,
onCreate: function(){
$('loading-img-options').show();
},
onComplete: function (t) {
$('loading-img-options').hide();
$('product_options').show();
}
});
}
the above function uses Ajax.Updater. You can also use Ajax.Request to get the result to juggle with.
function stripslashes(str) {
return str.replace(/\\'/g,'\'').replace(/\"/g,'"').replace(/\\\\/g,'\\').replace(/\\0/g,'\0');
}
function get_products(){
product = $('product');
cat_id = $('category').value;
new Ajax.Request('<?php echo Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_WEB); ?>offerte/index/getproducts',
{method: 'get', parameters: {cat_id: cat_id, mode: 'offerte'},
onCreate: function(){
$('product-loading').show();
$('product_options').hide();
},
onSuccess: function(t) {
resp = jQuery.parseJSON(t.responseText);
$('prod-container').innerHTML = resp.options ? stripslashes(resp.options) : '<?php echo $this->__('No options found') ?>';
$('product-loading').hide();
}
});
}
(please note I use JQuery to parseJSON. You can also use String.evalJSON, but I was lazy here :-)
Using Ajax.Request you need to return the result from the controller as JSON. I used the code below in my controller to return JSON to our phtml to use in the onSuccess Callback function above:
$this->getResponse()->setBody(Zend_Json::encode($result));
Hope this is of any help
I am using jqgrid and ajaxFileUpload.js script in order to pass parameters and files to a php script. The structure of the code is like this:
...
url:url_1.php,
beforeSubmit: function (postdata,formid)
{
$.ajaxFileUpload (
{
url: url_2.php,
...
success:
error:
}),
return[true,""];
},
afterSubmit: function(reponse,postdata)
{
...
return [true,'',''];
}
I have a dilemna:
According to the jqgrid behaviour, url_2.php is called, then url_1.php.
url_2.php handles the data (parameters + file), url_1.php handles nothing.
url_2.php could return an error or message (e.g "already exist") but, the errors are displayed in the form by the aftersubmit event, and this event receives error from url_1.php !!!
I suppose that I am obliged to put the ajaxfileupload in the beforesubmit event !!!
Any ideas to solve this dilemna ?
You can use jquery form plugin and jqGrid dataProxy method instead.
useDataProxy: true,
dataProxy : function (opts, act) {
opts.iframe = true;
var $form = $('#FrmGrid_' + $grid.jqGrid('getGridParam', 'id'));
//Prevent non-file inputs double serialization
var ele = $form.find('INPUT,TEXTAREA,SELECT').not(':file');
ele.each(function () {
$(this).data('name', $(this).attr('name'));
$(this).removeAttr('name');
});
//Send only previously generated data + files
$form.ajaxSubmit(opts);
//Set names back after form being submitted
setTimeout(function () {
ele.each(function () {
$(this).attr('name', $(this).data('name'));
});
}, 200);
};
For example http://jqgrid-php.net file fileUpload class uses this. This is described in How to force dataProxy call in form editing if editurl is set in jqgrid also.
how do I do two xhr.gets one after the other using dojo ?
I have ....
require(["dojo/_base/xhr", "dojo/dom", "dojo/domReady!"],
function(xhr, dom) {
// Using xhr.get, as very little information is being sent
xhr.get({
// The URL of the request
url: "inc/etl2json.php?item=Execs",
// The success callback with result from server
load: function(execContent) {
dom.byId("Execs").innerHTML = execContent;
},
// The error handler
error: function() {
// Do nothing -- keep old content there
}
});
});
I would like to do another xhr.get to "inc/etl2json.php?item=Execs" and assign it to dom.byId("Elapsed").innerHTML = elapsedContent;
just call again xhr.get() inside the load function, well that if the content is supposed to change, else you could just use the same data retrieved the first time:
xhr.get({
load:function(data){
//use the first data you retrieved
xhr.get({
load: function(data2){
//do what you like with the nuew data
}
});
}
});
Although nesting is a straightforward solution it almost always leads to unreadable code, so I would do the same as #Ricardo did, but use the advantage of Dojo's Deferred (+ here) and employ chaining:
var requestUrl = "inc/etl2json.php?item=Execs";
xhr.get({ url: requestUrl})
.then(function(results) {
dom.byId("execs").innerHTML = results;
})
.then(function(results) {
return xhr.get({ url: requestUrl});
})
.then(function(results) {
dom.byId("elapsed").innerHTML = results;
})
See it in action at jsFiddle: http://jsfiddle.net/phusick/73X88/
I think you should add another xhr call for the elapsedContent. I don't see any relation between the two calls so you should make them separate. Nesting one in another is not necessary.
just add
xhr.get({
// The URL of the request
url: "inc/etl2json.php?item=Execs",
// The success callback with result from server
load: function(elapsedContent) {
dom.byId("Elapsed").innerHTML = elapsedContent;
},
// The error handler
error: function() {
// Do nothing -- keep old content there
}
});
How do I use paramaters with Valums Uploader and Codeigniter?
With Valums the parameters are set like so:
var uploader = new qq.FileUploader({
element: document.getElementById('file-uploader'),
action: '/server-side.upload',
// additional data to send, name-value pairs
params: {
param1: 'value1',
param2: 'value2'
}
});
or using
uploader.setParams({
anotherParam: 'value'
});
if you want it to be aware of the state of your app/
subD="/Pic"
function selectGaleryName()
{
subD=subD+"/3"
alert(subD) // /Pic/3
}
var uploader = new qq.FileUploader({
element: document.getElementById('UploadFile'),
action: 'http://localhost/Farainform/manager/upload.php'
// additional data to send, name-value pairs
onComplete: function(id, fileName, responseJSON){
selectGaleryName();
uploader.setParams({
subDirectory : subD
});
},
});
if you want to set an id and a description for an image you can set these in javascript and then send these. So something like (im using jQuery here):
var description = $('#input_description').val(); //This can be an input
var id = $('#input_description').att('id');
var uploader = new qq.FileUploader({
element: document.getElementById('file-uploader'),
action: '/server-side.upload',
// additional data to send, name-value pairs
params: {
description: description,
id: id
}
});
Note I havent tested this code and its for demonstration purposes.
$_GET was always destroyed in the 1.7.3 branch but upgrade to the new CodeIgniter Reactor 2.0 and you'll find that GET strings work out of the box.
When upgraded, use this syntax:
$this->input->get('value1');
I don't know why it is not documented on Valums page, but apparently parameters should be sent not like this
params: {
param1: 'value1',
param2: 'value2'}
But like this
data: {param1: 'value1',
param2: 'value2'}
On server side you could get them with $_REQUEST['param1'];
You have to use PHP's input stream in order to obtain the data.
$fp = fopen('php://input', 'r');
Then read the data as you normally would with a regular file using fread(). Refer to valum's server side code located in server/php.php within the download.
Two related issues that I ran into that might help someone out:
1) var uploader causes issues - try using something like ajaxuploader instead
2) the documented setParams is incorrect for the latest release - it should be setData
The end result should be something like this:
var ajaxuploader = new AjaxUpload(button, {
action: 'your-server-script.php',
name: 'myfile',
onSubmit : function(file, ext){
ajaxuploader.setData({
somevar : 'somevalue',
anothervar : 'anothervalue'
});
)};
