how to save facebook access token after success - php

when user allow my app i receive this type of success url:
http://localhost/fbapp/app.php#access_token=AAAAALY8OpPABAM67auStdfgdfOdfgdfgdenqEt9QZCGD2a1h3iWFrhmNWqOf8l4a9RQ8tAJCM9y5QbYpsP6sT1g0ZCXDhtZCECZApGb&expires_in=6604
i am trying $_GET['access_token'] to save access token, but it's not working,
i want to know that how to get access token from this url..

From your use of $_GET, I'm assuming you are talking about PHP. Unfortunately, hash tags are never sent to the server. They only live on the client side so you need to use some javascript to then make a call to a PHP script.
Example:
<script type="text/javascript">
var HashSearch = new function () {
var params;
this.set = function (key, value) {
params[key] = value;
this.push();
};
this.remove = function (key, value) {
delete params[key];
this.push();
};
this.get = function (key, value) {
return params[key];
};
this.keyExists = function (key) {
return params.hasOwnProperty(key);
};
this.push= function () {
var hashBuilder = [], key, value;
for(key in params) if (params.hasOwnProperty(key)) {
key = escape(key), value = escape(params[key]); // escape(undefined) == "undefined"
hashBuilder.push(key + ( (value !== "undefined") ? '=' + value : "" ));
}
window.location.hash = hashBuilder.join("&");
};
(this.load = function () {
params = {}
var hashStr = window.location.hash, hashArray, keyVal
hashStr = hashStr.substring(1, hashStr.length);
hashArray = hashStr.split('&');
for(var i = 0; i < hashArray.length; i++) {
keyVal = hashArray[i].split('=');
params[unescape(keyVal[0])] = (typeof keyVal[1] != "undefined") ? unescape(keyVal[1]) : keyVal[1];
}
})();
}
$.ajax({
type: "POST",
url: '/store_access.php',
data: 'access_token='+escape(HashSearch.get('access_token'),
dataType: "html",
success: function(response) {
alert('Access Token Stored');
}
});
</script>
I found the HashSearch function here: Retrieve specific hash tag's value from url
Also, I assumed jquery on the post to your script, but you could use anything to make the call. You could even just add an image to the body with a url that includes the token.

You are using the client-side authentication auth URL instead of the server side URL which is why you are getting an access_token as part of the URL fragment instead of as a GET variable.
Remove response_type=token from your auth URL and then follow the Server Side Authentication.

Load() not working to call a PHP template when submitting a form

I'm trying to load a php file into a div on submission of a form. At the moment everything fires bar this line $('#signupform').load('newsletter-signup-call.php');, I've just got a simple echo request in there and it doesn't fire. If I goto that template it works though.
Where am I going wrong? Could I possibly fire two Ajax calls (as that in itself works) but there seems to be issues with load.
<script>
$("#signupForm").submit(function(e) {
e.preventDefault();
var form = $(this);
var email = $("#EmailAddress").val();
$.ajax({
type: "POST",
url: form.attr('action') + '?email=' + email,
data: form.serialize(),
beforeSend: function(){
$(".newsletter-loading").show().css({"display":"inline-block"});
},
success: function(data)
{
console.log(data); //data contain response from your php script
register_signup();
register_prefs();
(function() {
window.sib = {
equeue: [],
client_key: "xxx"
};
/* OPTIONAL: email for identify request*/
window.sib.email_id = email;
window.sendinblue = {};
for (var j = ['track', 'identify', 'trackLink', 'page'], i = 0; i < j.length; i++) {
(function(k) {
window.sendinblue[k] = function() {
var arg = Array.prototype.slice.call(arguments);
(window.sib[k] || function() {
var t = {};
t[k] = arg;
window.sib.equeue.push(t);
})(arg[0], arg[1], arg[2]);
};
})(j[i]);
}
var n = document.createElement("script"),
i = document.getElementsByTagName("script")[0];
n.type = "text/javascript", n.id = "sendinblue-js", n.async = !0, n.src = "https://sibautomation.com/sa.js?key=" + window.sib.client_key, i.parentNode.insertBefore(n, i), window.sendinblue.page();
})();
sendinblue.track('marketing');
$(".newsletter-loading").hide();
form.replaceWith("<br /><p>Thanks for signing up! You'll receive an email with your discount.</p>");
}
});
});
function register_prefs(){
var email = $("#EmailAddress").val();
Cookies.set('Address', email, { expires: 100000 });
$('#signupform').load('newsletter-signup-call.php');
}
function register_signup(){
ga( 'send', 'event', 'Newsletter Sign Up', 'submit' );
}
</script>
Try to console.log the response status to see what's going wrong
function register_prefs(){
//see if this function is triggered
console.log('register_prefs function triggered')
var email = $("#EmailAddress").val();
Cookies.set('Address', email, { expires: 100000 });
$('#signupform').load('newsletter-signup-call.php', function( response, status, xhr ){
console.log('Server response : ', response)//The serve response
console.log('Status Message : ', [xhr.status, xhr.statusText])//See the status of your request, if any error it should be displayed here
});
}
BUT, Why perform another server call with load, when your are already using ajax, you can return the html in the first call in a json object {Mydata: ..., MyHTML: ...} and just use $('#signupform').html(data.MyHTML) on success.
Also, not sure but I'm suspecting a malformed URL, try this instead '/newsletter-signup-call.php' or an absolute path just to be sure.

Can't send post to PHP script from nodejs and receive echo

I got the following code from here
I've tried this code with variable data being equal to 'test=yes' or with data being equal to {test:'yes'}
Here is the php script
if(isset($_POST['test'])){
error_log("inside");
echo "and I'd also like to return this";
};
And here is the nodejs piece of code:
function postToPHP(data, path){
var httpreq = require('http');
var querystring = require("querystring");
var data = querystring.stringify(data);
var options = {
host : 'localhost',
path : 'www' + path, //path is well defined in the actual code
method : 'POST',
headers : {
'Content-Type' : 'application/x-www-form-urlencoded',
'Content-Length' : data.length
}
};
var buffer = "";
var reqPost = httpreq.request(options, function(res) {
res.on('data', function(d) {
buffer = buffer+data;
});
res.on('end', function() {
return buffer;
});
});
reqPost.write(data);
reqPost.end();
}
And the call of postToPhp
//treat message?
var message = "test=yes";
//OR
var message = "{test:'yes'}";
var buffer = postToPHP(message,"path");
console.log("buffer from PHP",buffer);
buffer is undefined
Nothing is shown in the error log and I assume something is not working with the code that I can't figure so I hope someone can help me figure this one out.

upload image and store into my folder using jquery and php the below code procedure [duplicate]

Admittedly, there are similar questions lying around on Stack Overflow, but it seems none quite meet my requirements.
Here is what I'm looking to do:
Upload an entire form of data, one piece of which is a single file
Work with Codeigniter's file upload library
Up until here, all is well. The data gets in my database as I need it. But I'd also like to submit my form via an AJAX post:
Using the native HTML5 File API, not flash or an iframe solution
Preferably interfacing with the low-level .ajax() jQuery method
I think I could imagine how to do this by auto-uploading the file when the field's value changes using pure javascript, but I'd rather do it all in one fell swoop on for submit in jQuery. I'm thinking it's not possible to do via query strings as I need to pass the entire file object, but I'm a little lost on what to do at this point.
Can this be achieved?
It's not too hard. Firstly, take a look at FileReader Interface.
So, when the form is submitted, catch the submission process and
var file = document.getElementById('fileBox').files[0]; //Files[0] = 1st file
var reader = new FileReader();
reader.readAsText(file, 'UTF-8');
reader.onload = shipOff;
//reader.onloadstart = ...
//reader.onprogress = ... <-- Allows you to update a progress bar.
//reader.onabort = ...
//reader.onerror = ...
//reader.onloadend = ...
function shipOff(event) {
var result = event.target.result;
var fileName = document.getElementById('fileBox').files[0].name; //Should be 'picture.jpg'
$.post('/myscript.php', { data: result, name: fileName }, continueSubmission);
}
Then, on the server side (i.e. myscript.php):
$data = $_POST['data'];
$fileName = $_POST['name'];
$serverFile = time().$fileName;
$fp = fopen('/uploads/'.$serverFile,'w'); //Prepends timestamp to prevent overwriting
fwrite($fp, $data);
fclose($fp);
$returnData = array( "serverFile" => $serverFile );
echo json_encode($returnData);
Or something like it. I may be mistaken (and if I am, please, correct me), but this should store the file as something like 1287916771myPicture.jpg in /uploads/ on your server, and respond with a JSON variable (to a continueSubmission() function) containing the fileName on the server.
Check out fwrite() and jQuery.post().
On the above page it details how to use readAsBinaryString(), readAsDataUrl(), and readAsArrayBuffer() for your other needs (e.g. images, videos, etc).
With jQuery (and without FormData API) you can use something like this:
function readFile(file){
var loader = new FileReader();
var def = $.Deferred(), promise = def.promise();
//--- provide classic deferred interface
loader.onload = function (e) { def.resolve(e.target.result); };
loader.onprogress = loader.onloadstart = function (e) { def.notify(e); };
loader.onerror = loader.onabort = function (e) { def.reject(e); };
promise.abort = function () { return loader.abort.apply(loader, arguments); };
loader.readAsBinaryString(file);
return promise;
}
function upload(url, data){
var def = $.Deferred(), promise = def.promise();
var mul = buildMultipart(data);
var req = $.ajax({
url: url,
data: mul.data,
processData: false,
type: "post",
async: true,
contentType: "multipart/form-data; boundary="+mul.bound,
xhr: function() {
var xhr = jQuery.ajaxSettings.xhr();
if (xhr.upload) {
xhr.upload.addEventListener('progress', function(event) {
var percent = 0;
var position = event.loaded || event.position; /*event.position is deprecated*/
var total = event.total;
if (event.lengthComputable) {
percent = Math.ceil(position / total * 100);
def.notify(percent);
}
}, false);
}
return xhr;
}
});
req.done(function(){ def.resolve.apply(def, arguments); })
.fail(function(){ def.reject.apply(def, arguments); });
promise.abort = function(){ return req.abort.apply(req, arguments); }
return promise;
}
var buildMultipart = function(data){
var key, crunks = [], bound = false;
while (!bound) {
bound = $.md5 ? $.md5(new Date().valueOf()) : (new Date().valueOf());
for (key in data) if (~data[key].indexOf(bound)) { bound = false; continue; }
}
for (var key = 0, l = data.length; key < l; key++){
if (typeof(data[key].value) !== "string") {
crunks.push("--"+bound+"\r\n"+
"Content-Disposition: form-data; name=\""+data[key].name+"\"; filename=\""+data[key].value[1]+"\"\r\n"+
"Content-Type: application/octet-stream\r\n"+
"Content-Transfer-Encoding: binary\r\n\r\n"+
data[key].value[0]);
}else{
crunks.push("--"+bound+"\r\n"+
"Content-Disposition: form-data; name=\""+data[key].name+"\"\r\n\r\n"+
data[key].value);
}
}
return {
bound: bound,
data: crunks.join("\r\n")+"\r\n--"+bound+"--"
};
};
//----------
//---------- On submit form:
var form = $("form");
var $file = form.find("#file");
readFile($file[0].files[0]).done(function(fileData){
var formData = form.find(":input:not('#file')").serializeArray();
formData.file = [fileData, $file[0].files[0].name];
upload(form.attr("action"), formData).done(function(){ alert("successfully uploaded!"); });
});
With FormData API you just have to add all fields of your form to FormData object and send it via $.ajax({ url: url, data: formData, processData: false, contentType: false, type:"POST"})

jQuery AJAX Request Doesn't Work on Page Load, However, It Does Work from Debug Console

Turning off asynchronous requests in jQuery fixed the issue.
I have the following Javascript & AJAX request (using jQuery) in my page:
"use strict";
var hsArea, counter, hotspots, count;
counter = 4;
count = 0;
hotspots = {};
function fetchHotspotList() {
$.getJSON ('/alpha/engine/hotspots/gethotspot.php', {'type' : 'list'}, function(json) {
hotspots = json;
});
}
function displayHotspot(type, id, number) {
$.ajax({
url: '/alpha/engine/hotspots/gethotspot.php',
dataType: 'json',
data: {'type' : type, 'id' : id},
success: function(json) {
console.log(json);
var hotspot, extract;
extract = json.content;
extract = extract.replace(/<(?:.|\n)*?>/gm, '');
extract = extract.substring(0, 97);
extract = extract + "...";
json.content = extract;
hotspot = document.createElement("div");
hsArea.append(hotspot);
hotspot.setAttribute('class','hotspot');
hotspot.setAttribute('id','hotspot' + number);
$(hotspot).css('position', 'absolute');
$(hotspot).css('top', number * 100 + 100);
$(hotspot).css('left', number * 100 + 110);
hotspot.innerHTML = "<h1>"+ json.title + "</h1><p>" + json.content + "</p>";
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus, errorThrown);
}
});
}
function listHotspots() {
for(count = 0; count < counter; count++) {
(function(count) {
displayHotspot('scribble',hotspots[count], count);
count = count + 1;
})(count);
}
}
function loadHotspots() {
fetchHotspotList();
listHotspots();
}
$(document).ready(function() {
hsArea = $("#hotspotArea");
fetchHotspotList();
listHotspots();
});
(Sorry the formatting is a bit off!) - Now, the $(document).ready() function assigns the hsArea variable as it should, however, a combination of fetchHotspotList() and listHotspots() returns:
Uncaught TypeError: Cannot call method 'replace' of null
However, if in the Google Chrome Javascript console, I run:
loadHotspots();
it fetches the data from the AJAX request and displays it properly on the page. At first I thought the problem was that I Wasn't using the $(document).ready() handler, but adding it hasn't fixed it. Neither has using an onload handler inside of the body tag.
Any help would be greatly appreciated.
Regards,
Ben.
It's probably due to the fact that your listHotSpots function is called before fetchHotSpots returns (since it's an async call).
You're better off chaining the execution of listHotSpots to the completion of fetchHotSpots, like so:
function fetchHotspotList() {
$.getJSON ('/alpha/engine/hotspots/gethotspot.php', {'type' : 'list'}, function(json) {
hotspots = json;
listHotSpots();
});
}
You may be better off modifying listHotSpots to take the json data returned from your AJAX call. Hope this helps!

Jquery and ajax, my function for username checking?

I have written this ajax request for username checking...
function check_username() {
var username = $("#username").val();
$('.loading').fadeIn().delay(100);
$.post("ajax.php", {
username: $('#username').val(),
}, function (response) {
$('.error, .success').hide();
setTimeout(function () {
$('.loading').hide();
finishAjax('username', response);
}, 1000);
});
return false;
}
function finishAjax(id, response) {
$('#' + id).after(response).fadeIn(1000);
}
It all works fine just a couple of questions,
Can this code be improved in any way, this is the first ever one I have wrote so I wouldn't know.
Is there a way to make this a function for all my ajax requests rather than just username checking, so it can be used for email checking and such too. I am not sure on how to make a function like that would I have to pass variables on my onblur event which is attached to my form, at the minute it looks like this.
Is there a way to stop the ajax from running if the same error is there as previous, ie, string length should be over 3, so someone inputs AJ, and the error message 'must be over 3 characters' comes up, it the user then triggers the onblur event again, with the value of AJ, or CG, then the same error comes up, triggering a script that is useless and using memory.
Is there a way to make the ajax request with every character the user enters?
My ajax php is as follows...
<?php
require('dbc.php');
if (isset($_REQUEST['username'])) {
$q = $dbc -> prepare("SELECT username FROM accounts WHERE username = ?");
$q -> execute(array($_REQUEST['username']));
if (strlen($_REQUEST['username']) < 3) {
echo '<div class="error">Has to be at least 3 characters</div>';
}
elseif ($q -> rowCount() > 0) {
echo '<div class="error">Username already taken</div>';
}
else {
echo '<div class="success">Username available</div>';
}
}
?>
To answer 1 & 2. I would turn it into a plugin and do something along these lines.
$.fn.checkValid = function(options)
{
var response = function(response) {
var setClass = '';
var $span = $(this).data('checkValidTip');
if ($span)
{
$span.remove();
}
if (response === undefined) return;
setClass = (response.valid ? 'valid' : 'invalid');
var $span = $('<span>' + response.msg + '</span>');
$(this)
.data('checkValidTip', $span)
.after($span);
$span.hide()
.fadeIn(1000)[0]
.className = setClass;
};
var ajaxOptions = {
type: 'GET',
url: 'ajax.php',
success: response,
dataType: 'json'
};
this.each(function() {
var that = this;
var ajaxRequest = ajaxOptions;
ajaxRequest.data = {};
ajaxRequest.data[options.key] = this.value;
ajaxRequest.context = that
$.ajax(ajaxRequest);
});
};
Usage
$('#username, #email').blur(function() {
$(this).checkValid({ key: this.id });
});
PHP changes
You should make your PHP function return a JSON, instead of HTML i.e.
<?php
// Do your sql statements here, decide if input is valid or not
$arr = array('valid' => $is_valid,
'msg' => $error_or_good_msg
);
echo json_encode($arr);
/* For example will output:
{
"valid": "false",
"msg": "<b>Error: Must be at least 2 characters</b>"
}
Which can be read directly as response.valid
or response.msg from within response() function
*/
To answer question 3: short answer is no. For this to work, you should have basic validation in JS. The best option would be to use a plugin that uses objects for validation parameters, that way you can output your validation requirements dynamically from your database, from within PHP using json_encode i.e. your output format would be:
var validations = {
username: {
min_chars: 4,
max_chars: 10,
valid_chars: 'qwertyuiopasdfghjklzxcvbnm_-'
},
email: {
regex: /./ //your magic regex here
}
};

To answer 4, just change the event as above from .blur to .keyup should do the trick.
