Zend Gdata Youtube and auto login

Question

i think all you need is to get a access token and set it to a session value "$_SESSION['sessionToken']". Combination of javascript and PHP will need to do this. previously i always have to grant access or deny it while using Picasa web API but after changes that i described below, grant or access page is no longer needed.

I have not integrated youtube with zend Gdata but have integrated Picasa web Albums using it

make a login using javascript popup and get a token for a needed scope. below is a javascript code. change your scope to youtube data as in this scope for picasa is used.. click function "picasa" on your button onclick.

var OAUTHURL    =   'https://accounts.google.com/o/oauth2/auth?';
var VALIDURL    =   'https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=';
var SCOPE       =   'https://picasaweb.google.com/data';
var CLIENTID    =   YOUR_CLIENT_ID;
var REDIRECT    =   'http://localhost/YOUR_REDIRECT_URL'
var LOGOUT      =   'http://accounts.google.com/Logout';
var TYPE        =   'token';
var _url        =   OAUTHURL + 'scope=' + SCOPE + '&client_id=' + CLIENTID + '&redirect_uri=' + REDIRECT + '&response_type=' + TYPE;
var acToken;
var tokenType;
var expiresIn;
var user;
var loggedIn    =   false;

function picasa() {
    var win         =   window.open(_url, "windowname1", 'width=800, height=600'); 

    var pollTimer   =   window.setInterval(function() { 
        console.log(win);
        console.log(win.document);
        console.log(win.document.URL);
        if (win.document.URL.indexOf(REDIRECT) != -1) {
            window.clearInterval(pollTimer);
            var url =   win.document.URL;
            acToken =   gup(url, 'access_token');
            tokenType = gup(url, 'token_type');
            expiresIn = gup(url, 'expires_in');
            win.close();

            validateToken(acToken);
        }
    }, 500);
}

function validateToken(token) {
    $.ajax({
        url: VALIDURL + token,
        data: null,
        success: function(responseText){  
            //alert(responseText.toSource());
            getPicasaAlbums(token);
            loggedIn = true;
        },  
        dataType: "jsonp"  
    });
}

function getPicasaAlbums(token) {
    $.ajax({
    url: site_url+"ajaxs/getAlbums/picasa/"+token,
    data: null,
    success: function(response) {
        alert("success");

    }
});
}

function gup(url, name) {
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\#&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( url );
    if( results == null )
        return "";
    else
        return results[1];
}

Here i am making a ajax call in function "getPicasaAlbums" and setting token to a $_session there and after it i am able to get a album listing using zend queries. here is a some code of php file that i am calling using ajax in function "getPicasaAlbums".

function getAlbums($imported_from = '',$token = '') {
    //echo $imported_from; //picasa
    //echo $token; 

    $_SESSION['sessionToken'] = $token;// set sessionToken
            $client = getAuthSubHttpClient();
            $user = "default";

            $photos = new Zend_Gdata_Photos($client);
            $query = new Zend_Gdata_Photos_UserQuery();
            $query->setUser($user);

            $userFeed = $photos->getUserFeed(null, $query);

echo "<pre>";print_r($userFeed);echo "</pre>";exit;
}

i think this will help you a little in your task. relpace above "getAlbums" function's code with your youtube zend data code to retrieve data.

good example & referene of a login popup is here
