I need to get the number of likes for a given url.how to do it?
also can i get the total fancounts of a fb page?
Address
http://graph.facebook.com/?id=http://facebook.com
returns:
{"id": "http://facebook.com","shares": 54290530,"comments": 1244}
So to change id parametr for your URL and get your shares count via jQuery use:
jQuery(document).ready(function($){
$.getJSON(
"http://graph.facebook.com",
{ id : "http://facebook.com" }, //here should be your URL
function(json){
//var data = jQuery.parseJSON();
alert( json.shares );
}
);
});
Use Facebook's API. Just add the URL's you are interested in to the end of of this URL:
http://api.facebook.com/restserver.php?method=links.getStats&urls=
example:
http://api.facebook.com/restserver.php?method=links.getStats&urls=stackoverflow.com,serverfault.com
I think the fancount is just the "like" count of the URL for the FB page.
Source, with PHP code for parsing the output: Get likes on urls from Facebook
FQL link_stat would be a nice alternative to rest API (facebook is in process of deprecating the REST API)

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.

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 update my url, based on some checkboxes...
I now have an url that looks like www.mywebsite.com/index.php?city=Amsterdam
The city parameter I use to get data from mysql and display that on my page. On the page I also have some checkboxes. I want to update the url if a user clicks on a checkbox, refresh the page, and use the new url to make a new query to the database.
On http://api.jquery.com/serialize/ I found something I liked ;) The example on the bottom shows what I want. Only this example displays the result. Can someone help me to get that result in the url ?
So after clicking on some checkboxes I would like to have an url that looks like www.mywebsite.com/index.php?city=Amsterdam&single=Single2&multiple=Multiple3&radio=radio1
I know PHP, but my knowledge of jquery and ajax is 0 ;) I used google to search, but after some hours I still didn't find anything use-full. Is there someone who can help me ?
try this
$.ajax({
url:"www.mywebsite.com/index.php"; // path to your url
type: "get", //post or get
data:$('#yourFormID').serialize(),
success:function(){ //function called when ajax is completed
alert('done');
}
});
If you need to refresh the page with a new url, you need to serialize the form when user click on a checkbox and update the url (updating url will refresh page, if you don't want to refresh page, you will have to user pushstate functionality or a hash in the url).
Try this:
var $form = $('form');
$('#my-checkbox').on('click', function() {
window.location.search = '?' + $form.serialize();
});
I am trying to get the URL i see on my browser after i do an ajax request but the problem is that it changes the URL with the Ajax URL.
ex.
i am on domain.com/user/username
and the ajax URL that i call is in domain.com/posts/submit
when i echo $_SERVER['REQUEST_URI'] on the posts controller in submit function it will display the second URL and not the first... how can i assure and get the first inside the ajax function that its 100% valid and not changed by the user to prevent any bad action?
Thanks
There is HTTP_REFERER but I don't know if that works for javascript requests. Another problem of this: It won't work for all browsers.
You could try the following:
1.) As the user visits domain.com/user/username the current URL is saved with a token - let's say 5299sQA332 - into the database and the token is provided through PHP to Javascript
2.) The ajax request will send this token along with the other variables needed to the controller through POST
3.) In your ajax controller you search the database for the given token 5299sQA332 and there you have your first URL and you can be damn sure, that it hasn't been manupulated
:)
If I understand you correctly, you want to make sure the ajax call is coming from the page it is supposed to be on? In that case just pass a token with the call.
In the controller function set a token variable in session;
public function username() {
$this->session->set_userdata('ajax_token', time());
}
Then in the view with the js;
$.ajax({
url: '/user/username',
type: 'post',
data: 'whatever=bob&token='+<?php echo $this->session->userdata('ajax_token'),
success: function( data ) {
},
error: function( data ) {
}
});
Then in you form validation, do a custome callback to check they are the same.
Have you looked at CodeIgniter's Input Class ?
$this->input->get('something', TRUE);
i used javascript for it and it seems to work... hope not to have any problems in the future with it...
ps: i dont get why my other answer was deleted.. thats the answer anyway.
For a project I need to get the source code of web page of different other domains.
I have tried following code:
$('#container').load('http://google.com');
$.ajax({
url: 'http://news.bbc.co.uk',
type: 'GET',
success: function(res) {
var headline = $(res.responseText).find('a.tsh').text();
alert(headline);
}
});
Still I am not getting any results but just a blank alert box.
By default all browsers restrict cross-domain requests, you can get around this by using YQL as a proxy. See a guide here: http://ajaxian.com/archives/using-yql-as-a-proxy-for-cross-domain-ajax
For security reasons scripts aren't able to access content from other domains. Mozilla has a long article about HTTP access control, but the bottom line is that without the website themselves adding support for cross-domain requests, you're screwed.
This code is Working Perfectly with the help of JQuery and YQL
$(document).ready(function(){
var container = $('#target');
$('.ajaxtrigger').click(function(){
doAjax($(this).attr('href'));
return false;
});
function doAjax(url){
if(url.match('^http')){
$.getJSON("http://query.yahooapis.com/v1/public/yql?"+
"q=select%20*%20from%20html%20where%20url%3D%22"+
encodeURIComponent("http://www.yahoo.com")+
"%22&format=xml'&callback=?",
function(data){
if(data.results[0]){
var data = filterData(data.results[0]);
container.html(data);
} else {
var errormsg = '<p>Error: could not load the page.</p>';
container.html(errormsg);
}
}
);
} else {
$('#target').load(url);
}
}
function filterData(data){
data = data.replace(/<?\/body[^>]*>/g,'');
data = data.replace(/[\r|\n]+/g,'');
data = data.replace(/<--[\S\s]*?-->/g,'');
data = data.replace(/<noscript[^>]*>[\S\s]*?<\/noscript>/g,'');
data = data.replace(/<script[^>]*>[\S\s]*?<\/script>/g,'');
data = data.replace(/<script.*\/>/,'');
return data;
}
});
The solution for your case is JSON with padding or JSONP.
You will need an HTML element that specified for its src attribute a URL that returns JSON like this:
<script type="text/javascript" src="http://differentDomain.com/RetrieveUser?UserId=1234">
You can search online for a more in-depth explanation, but JSONP is definitely your solution for this.
Do the following steps.
1: Add datatype:jsonp to the script.
2: Add a "callback" parameter to the url
3: Create a javascript function with name same as "callback" param value.
4: The output can be received inside javascript function.
Found one more solution for this :
function getData(url){
if(url.match('^http')){
$.get(url,
function(data){
process(data);
}//end function(data)
);//end get
}
}
This is really a pretty easier way to handle cross-domain requests. As some of the sites like www.imdb.com rejects YQL requests.
