Currently, I'm trying to create a page using instagram's api, showing recent pictures with a specific tag, as well as the user who posted it and the date posted. I'm also trying to have the infinite loading functionality, with ajax loading in more instagram posts as the page reaches the bottom.
Heres a link to the live site http://www.laithazzam.com/work/nukes/indexnew.php
Clicking the red yes will skip the video, and go straight to the instagram feed.
I'm currently using Christian Metz's solution found here, https://gist.github.com/cosenary/2961185
I am also having an issue with posting the date, in the first initial load, as well in the ajax loads. I was previously able to use this following code, before trying to implement Christian's php/ajax solution.
var date = new Date(parseInt(data.data[i].created_time) * 1000);
<p class='date'>"+(date.getMonth()+1)+"/"+date.getDate()+"/"+date.getFullYear()+"</p>
I guess what I don't understand, is how the ajax loading function, is actually functioning. How would I also pull the name, and date through the ajax loading success function as well?
$.ajax({
type: 'GET',
url: 'ajax.php',
data: {
tag: tag,
max_id: maxid
},
dataType: 'json',
cache: false,
success: function(data) {
// Output data
$.each(data.images, function(i, src) {
$("#instafeed").append('<img src="' + src + '">');
});
// Store new maxid
$('#more').data('maxid', data.next_id);
}
});
});
The data parameter of the success handler function is populated from whatever JSON ajax.php returns and the structure will match accordingly. It looks like the images attribute of that object only has an array of URLs for the images and no other data.
You'll need to update this section of the PHP script to return more than just the array of URLs for the images and also include the additional data retrieved from the Instagram API.
Try updating the last part to this:
echo json_encode(array(
'next_id' => $media->pagination->next_max_id,
'images' => $media->data
));
Then you'll have full access to all the media data, not just the URL.

I want to get content using ajax from an admin page and append it to all content pages on right hand side.
I have this script:
$.ajax({
url: '/Quicklinks-Content-Admin',
type: 'GET',
success: function(data) {
var quicklinks_list = [];
$('.content-inner .blogentries ul li').each(function (i, v) {
v = $(v);
quicklinks_list.push({
text: $('.blogBody a', v).text().trim(),
href: $('.blogBody a', v).attr("href"),
bg: $(v).find('.sws-inline-content img').attr('src')
});
console.log(i);
console.log(quicklinks_list[i].text);
console.log(quicklinks_list[i].href);
console.log(quicklinks_list[i].bg);
$(".quicklinks-inner").append('<div class="right-quicklink ql' + i + '"><div class="quicklink-inner"><div class="quicklink-title">' + quicklinks_list[i].text + '</div><div class="background-cover"></div></div></div>');
$('.ql'+ i +' .background-cover').css("background-image", 'url("' + quicklinks_list[i].bg + '")');
$(".quicklink-title a").html(function(index, old) {
return old.replace(/(\b\w+)$/, '<span class="lastWord">$1</span>');
});
});
}
});
With this script I extract the content from a blog list from "/Quicklinks-Content-Admin" page which is a link in two variable (text and href) and one more variable for the image. After this I want to insert the content from variables to all content pages.
Actually, that script insert the content just for that admin page, instead to put it on every single page.
Why does it happen and how to solve the problem ?
AJAX is just a procedure for sending data from/to the current webpage to a back-end PHP (or aspx etc) file.
If the transmitted data should be remembered (for example, to update other pages), then you can store it in a database and refactor the other pages to read from the database for data when constructing each of those pages.
If you require the AJAX data to be added to other areas on the same page as the AJAX routine, for example in sidebar sections that are $.load()ed when the page is constructed, just use javascript to update those areas. Or, use javascript to call another $.load() of the data into that div.
Regardless how you do it, you will either use javascript to update an area on the page you are on, or you will store the data on the server (usually using a database, but you can also use a server-side file) and make the other PHP pages read that stored information when building their pages.
I'm trying to make a custom page in the adminpanel of Prestashop where the shopowner can fill in his upcoming events that will appear in a column in the header.tpl page. The templates and controller are working so far, with a structure based on an answer here at Stack Overflow:
How to create a new page in prestashop admin panel?
Now I have made in the content.tpl (with the added custom JavaScript and CSS files) the form with the input fields. The next step is to send it to the controller to save it in the database. But I'm stuck this part. I can't find how I can nicely submit the form to the controller. First I tried it with an Ajax function but I couldn't find the right way. Also without Ajax no success.
$.ajax({
type: 'POST',
headers: { "cache-control": "no-cache" },
url: baseUri + '?rand=' + new Date().getTime(),
async: true,
cache: false,
dataType : "json",
data:{
processEvents: true,
ajax: 'true',
controller: 'AdminEvents',
token: static_token
},
//success: function(jsonData){
//}
});
This is an example of an Ajax function that I tried. My questions:
How does other tpl or js files receive the baseUri, where is that
variable set?
What is the function of the ?rand date and time in that line? A kind
of security token?
What is the url of the controller? Also the url when I use
I guess the processEvents : true and Ajax : true is for security
reasons and to check if the form is submitted by Ajax or not?
Why is it necessary to send the controller name?
Where does the token come from?
Questions about the controller:
Which (Prestashop default functions) can or do need to use? For
example:
if (Tools::isSubmit('name')){
etc.
if (Tools::getValue('create_account')){
etc.
Can I use that functions anywhere or maybe only in an Init function?
A lot of questions, feel free to answer only a part of it, I just need a good push in the right direction, searching and reading in the online documentation and on the internet doesn't brought me the solution and brainwashed me a little.
EDIT:
I made a little progress by myself:
Where does the token come from?
What is the url of the controller? Also the url when I use
With the tools getAdminTokenLite and the controller name I generated the controller url:
$token = '?controller=AdminEvents&token='.Tools::getAdminTokenLite('AdminEvents');
The url to post to is the token plus the domain, admin directory and index.php.
With the tool getValue I get the POST data like in PHP with $_POST["name"].
Tools::getValue('event_name')
So its working but I guess it can be better with other Presta default tools.
I know that it's very late to answer you, but for sure it will help other mates with same problem.
Here is an example about how to implement ajax calls in Prestashop 1.6 on Admin panel using ANY Controller from BackOffice (if you want also, you can use ajax.php controller, but I'm using for this AdminImportController() )
tpl part:
$('#mybtn').click(function(e) {
var data = $('#datalist').val();
// Ajax call with secure token
$.post( "{$current|escape:'html':'UTF-8'}&token= {$token|escape:'html':'UTF-8'}",
{ ajax: true, action: "MyFunction", mydata: data } );
});
And in admin controller side:
public function ajaxProcessMyFunction()
{
// Get param
$mydata = (int)Tools::getValue('mydata');
$answer = 0;
if( $mydata > 0 ) {
$this->importProfList = Db::getInstance()->executeS(
"SELECT * FROM .... LIMIT 1"
);
...
$answer = $someOperationResult;
}
// Response
die(Tools::jsonEncode(array(
'answer' => htmlspecialchars($answer)
)));
}
Tested and working like a charm.

I'm creating a webproject in pyramid where I'd like to update a table every few secondes. I already decided to use ajax, but I'm stuck on something.
On the client side I'm using the following code:
function update()
{
var variable = 'variable ';
$.ajax({
type: "POST",
url: "/diagnose_voorstel_get_data/${DosierID}",
dataType: "text",
data: variable ,
success: function (msg) {
alert(JSON.stringify(msg));
},
error: function(){
alert(msg + 'error');
}
});
}
Pyramid side:
#view_config(route_name='diagnose_voorstel_get_data', xhr=True, renderer='string')
def diagnose_voorstel_get_data(request):
dosierid = request.matchdict['dosierid']
dosieridsplit = dosierid.split
Diagnoses = DBSession.query(Diagnose).filter(and_(Diagnose.code_arg == str(dosieridsplit[0]), Diagnose.year_registr == str(dosieridsplit[1]), Diagnose.period_registr == str(dosieridsplit[2]), Diagnose.staynum == str(dosieridsplit[3]), Diagnose.order_spec == str(dosieridsplit[4])))
return {'Diagnoses ' : Diagnoses }
Now I want to put this data inside a table with zpt using the tal:repeat statement.
I know how to use put this data in the table when the page loads, but I don't know how to combine this with ajax.
Can anny1 help me with this problem ? thanks in adance.
You can do just about anything with AJAX, what do you mean "there's no possibility"? Things become much cleaner once you clearly see what runs where and in what order - as Martijn Pieters points out, there's no ZPT in the browser and there's no AJAX on the server, so the title of the question does not make much sense.
Some of the options are:
clent sends an AJAX request, server does its server-side stuff, in the AJAX call success handler the client reloads the whole page using something like window.location.search='ts=' + some_timestamp_to_invalidate_cache. The whole page will reload with the new data - although it works almost exactly like a normal form submit, not much sense using AJAX like this at all.
client sends an AJAX request, server returns an HTML fragment rendered with ZPT which client then appends to some element on your page in the AJAX success handler:
function update()
{
var variable = 'variable ';
$.post("/diagnose_voorstel_get_data/${DosierID}")
.done(function (data) {'
$('#mytable tbody').append(data);
});
}
client sends an AJAX request, server returns a JSON object which you then render on the client using one of the client-side templating engines. This probably only make sense if you render your whole application on the client and the server provides all data as JSON.
I have opencart. function addToCart() that adds products to cart works normal on normal pages.
I made custom page where I have just button that triggers function addtoCart(). Just normal button..
On normal page(where it works) I get normal response.
Please look at this link of images:
http://imgur.com/7M1AR1B,FKjiU05,9ggmiMR#2
Third image is actually post that works OK, second picture is RESPONSE that works OK.
First picture is empty response which I get in custom page in open cart.
Do you have an idea why is this happening?
I use function addToCart() and use hard variable FOR TEST in that custom page, which means variables are always there to pass. I use hard variables so I don't have to explain how do I pass variables back in code(it works the same, it passes everything in debug). Problem is I get that "empty" response back only on custom made page. Response: [] ...
function addToCart() {
var product_id = 79;
var quantity = 1;
$.ajax({
url: 'index.php?route=checkout/cart/add',
type: 'post',
data: 'product_id=' + product_id + '&quantity=' + quantity,
dataType: 'json',
success: function (json) {
$('.success, .warning, .attention, .information, .error').remove();
if (json['redirect']) {
location = json['redirect'];
}
if (json['success']) {
$('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.success').fadeIn('slow');
$('#cart-total').html(json['total']);
$('html, body').animate({
scrollTop: 0
}, 'slow');
}
}
});
}
Possibilities to try
Using HTTPS to NON HTTPS or vice versa
Using www to non www domain or vice versa
Using a domain that isn't the same one as the one you're using to render the page
If none of the above are the issue, you'll need to work out what the exact differences are between the requests, though my guess is it's one of the three possibilities I've listed
The problem was, that I was adding a product without 1 needed attribute, therefore I always got empty response. There is an attribute in opencart where you have to setup to which store your product belongs. If you don't set that attribute if you are programatically adding a product into the store, you will add product, but you won't be able to add it to cart.
I've built an app that works, and uses forms to submit data. Once submitted, the view then redirects back to display the change. Cool. Django 101. Now, instead of using forms, I'm using Ajax to submit the data via a POST call. This successfully saves the data to the database.
Now, the difficult (or maybe not, just hard to find) part is whether or not it's possible to tell Django to add the new item that has been submitted (via Ajax) to the current page, without a page refresh. At the moment, my app saves the data, and the item shows up on the page after a refresh, but this obviously isn't the required result.
If possible, I'd like to use exactly the same view and templates I'm using at the moment - essentially I'd like to know if there's a way to replace a normal HTTP request (which causes page refresh) with an Ajax call, and get the same result (using jQuery). I've hacked away at this for most of today, so any help would be appreciated, before I pull all of my hair out.
I had a very similar issue and this is how I got it working...
in views.py
from django.utils import simplejson
...
ctx = {some data to be returned to the page}
if ajax == True:
return HttpResponse(simplejson.dumps(ctx), mimetype='json')
then in the javascript
jQuery.ajax({
target: '#id_to_be_updated',
type: "POST",
url: "/",
dataType: 'json',
contentType: "text/javascript; charset=\"utf-8\"",
data: {
'foo':foo,
'bar':bar,
},
success: function(data){
$("#id_to_be_updated").append(data.foo);
}
});
Here's how I did it:
The page that has the form includes the form like so
contact.html
{% include "contact_form.html" %}
This way it's reusable.
Next I setup my view code (this view code assumes the contact form needs to be save to the db, hence the CreateView):
class ContactView(CreateView):
http_method_names = ['post']
template_name = "contact_form.html"
form_class = ContactForm
success_url = "contact_form_succes.html"
There are a few things to note here,
This view only accepts pots methods, because the form will be received through the contact.html page. For this view I've setup another template which is what we included in contact.html, the bare form.
contact_form.html
<form method="POST" action="/contact">{% crsf_token %}
{{ form.as_p }}
</form>
Now add the javascript to the contact.html page:
$("body").on("submit", 'form', function(event) {
event.preventDefault();
$("#contact").load($(this).attr("action"),
$(this).serializeArray(),
function(responseText, responseStatus) {
// response callback
});
});
This POSTS the form to the ContactView and replaces whatever is in between #contact, which is our form. You could not use jquery's .load function to achieve some what more fancy replacement of the html.
This code is based on an existing working project, but slightly modified to make explaining what happens easier.
