I would like to know how to show a CQ5 page in a Facebook App without writing a dedicated sling servlet?
Facebook adds a form post to retrieve markup and insert into the iFrame.
Apparently, CQ5 pages doesn't allow POST operations unless you write a dedicated sling servlet to handle.
The page for some reason sits within /content/dam
Here's what the Facebook App add in the canvas:
<form action="<url>" method="post" target="iframe_canvas_fb_https" id="canvas_iframe_post_522050a15f2c72f17540952" onsubmit="return window.Event && Event.__inlineSubmit && Event.__inlineSubmit(this,event)"><input type="hidden" autocomplete="off" name="signed_request" value="TKQ-UKDi8meFDQgQaq_5c3LWD2R06EiibRdrTk7XldE.eyJhbGdvcml0aG0iOiJITUFDLVNIQTI1NiIsImlzc3VlZF9hdCI6MTM3Nzg0OTUwNSwidXNlciI6eyJjb3VudHJ5IjoiaGsiLCJsb2NhbGUiOiJlbl9HQiIsImFnZSI6eyJtaW4iOjIxfX19"><input type="hidden" autocomplete="off" name="locale" value="en_GB"></form>
<iframe class="smart_sizing_iframe" frameborder="0" scrolling="yes" id="iframe_canvas" name="iframe_canvas_fb_https" src='javascript:""' height="800" webkitallowfullscreen="" mozallowfullscreen="" oallowfullscreen="" msallowfullscreen="" style="height: 232px;"></iframe>

I'm using ASP.NET web forms and i need to post data to an iframe, the problem is that in web forms I have the main form tag(form1), so i need another form tag(form2), to post data to the iframe that is in the main form1.
Basically i have this:
<form method="post" id="form2" action="http://localhost:58903/WebForm1.aspx" target="webApp">
<input type="hidden" name="ValidationUserName" value="david" />
<input type="hidden" name="ValidationTokenId" value="13123132132" />
<button type="submit">Send info to inner iframe</button>
</form>
<form id="form1" runat="server">
<iframe id="webApp" name="webApp" src="http://localhost:58903/WebForm1.aspx" style="width: 800px; height: 800px;"></iframe>
</form>
With this approach in open a new tab, if i put the iframe outside it works ok, but if i do this the layout is changed and i don't want this.
Is this possible?
If all the forms are in the same domain you should not work with iframes.
What exactly are you trying to get here? didn't realize completely
Done it, it was missing the "name" attribute in the <form> tags.
I am using jQuery 1.6.4 with jQuery Mobile 1.0.1. I am running into an issue anytime you link to a page that then tries to do a 301 redirect.
I've setup a sample page at: http://www.widgetsandburritos.com/jquery-mobile-test/
The only thing on this page is the jQuery Mobile includes and a link to another page that has a 301 redirect somewhere else.
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
</head>
<body>
301 test
</body>
</html>
301test.php has the following content:
<?php
header( "HTTP/1.1 301 Moved Permanently" );
header( "Location: 301success.html" );
?>
This should just simply pass the browser to 301success.html. It works if you directly go to that URL
http://www.widgetsandburritos.com/jquery-mobile-test/301test.php
But when you click on the link from the page using jQuery Mobile, it shows "undefined" instead. Is jQuery Mobile currently incapable of handling redirects?
Any possible work arounds?
Thanks for your help.
EDIT [3/23/12 12:41AM CST]
I also posted this problem on the jQuery Mobile forums. Somebody there recommended adding rel="external" to the anchor tag. This technically works if all you are doing is making a link, but won't fix the issue if you get to the redirect via some other mechanism, such as a POST request.
To illustrate, I've setup a secondary test at http://www.widgetsandburritos.com/jquery-mobile-test/test2.html
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
</head>
<body>
<form method="post" action="301test.php">
<input type="submit" value="test" />
</form>
</body>
</html>
Instead of arriving at the 301test.php redirect page from a link, it's now the location of a form we're submitting to. The context this would be used, would be such that if you submit a form with errors, it would stay on the same page allowing you to correct the errors. If there were no errors, it redirects you to a success page. This is done to avoid submitting the form again if a user refreshes their browser. It works brilliantly in normal web applications. But in combo with jQuery Mobile it doesn't seem to work.
Just thought I'd give some additional context to anyone else following this issue.
Figured out the answer to my own problem. In the above, I mentioned that this was causing problems using the <form> tag. After browsing through the jQuery Mobile documentation I found this page: http://jquerymobile.com/test/docs/forms/forms-sample.html
The trick here is if you're doing a form, to force it to not use AJAX. You do this by adding
data-ajax="false" to the FORM tag.
So this changes
<form method="post" action="301test.php">
to
<form method="post" action="301test.php" data-ajax="false">
And just to reiterate what was said above. If you need to do something with an anchor link, just add rel="external" to it.
So this changes
301 test
to
301 test
The issue is deeper. Take a look here or here.
It seems that XMLHttpRequest object (the one used for doing AJAX requests) handles redirects on its own and returns the final response. Which means that jQuery Mobile can't know that it should update the URL.
The solution is to use the data-url attribute on the final page. It forces jQuery Mobile to update the URL in the browser. Kind of a workaround but far from being a hack.
By the way there are more issues with jQuery Mobile, AJAX and redirects - for instance if you click the browser's back button after an AJAX-redirect, jQuery Mobile (up till 1.1) might produce a final page under the URL of the redirecting page. Therefore using data-ajax="false" is a wise choice.
EDIT:
But even data-ajax="false" is not a bullet-proof solution. Using it splits your mobile app into multiple browser pages, which brings all sorts of browser differences to the party. For instance Firefox has so called bf cache whereas Chrome doesn't. This is an unholy mess and I'm starting to think that something like Sencha Touch is much better suited for developing pages that pretend to be mobile apps.
EDIT 2:
Alternatively, one could avoid regular form submissions and use own AJAX code for that and then switch pages based on the result, but I cannot resist thinking that it's 2012 and such things should automated and work flawlessly without sweating.
I'm currently building an application but even though I am logged in, I stay on the login page, and I do not get redirected. I used the data-ajax="false"
this is the code of the form:
<section id="login">
<h2>Want to take a ride? <span>Login</span></h2>
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post" data-ajax="false">
<?php if(!empty($feedback_error)): ?>
<div id="feedback_error">
<p><h1><?php echo $feedback_error ?></h1></p>
</div>
<?php endif; ?>
<input id="username" type="text" name="username" placeholder="username" />
<input id="password" type="password" name="password" placeholder="password" />
<p>Not yet signed up? <a href="register.php" >Register</a></p>
<input type="submit" name="btnLogin" data-theme="b" value="Sign in">
</form>
</section>
I just added a FBML application to my fan page but I can't make JS to work ... though I read the FBJS best practices ... I guess I am missing something.
here is the current code :
<form action="" method="post" target="_blank">
<input type="text" name="email" id="emailInput" onclick="document.getElementById(‘emailInput’).setTextValue(‘Hi!’);" value="votre adresse email" alt="Entrez votre email" />
<input type="hidden" name="place" value="facebook" />
<br/>
<input type="submit" name="submit" class="submitInput" value="" alt="Valider" />
</form>
The onclick event seems not to work but I can't get any answers from my research over Internet ...
Any help welcome ;)
Cheers guys.
Gotye.
Use Firebug or Chrome tools to verify that the id is actually emailInput, and that the Facebook FBML parser didn't append a prefix to the ID. But FBML pages have been deprecated so you will be better off switching to an iframe fan page so you aren't running the risk of having Facebook kill your FBML fan page. Also, javascript is a ton easier in iframe pages and can be called without having to wait for a click event to fire.
I have a frameset with an iFrame with a form in it.
When I submit the form IE8 does not send the form values. Firefox does.
Without the ambient frameset it works.
This is my code:
form.php:
<form method="post" action="doit.php" name="myForm" id="myForm" target="myFrame">
<input type="hidden" id="customer__csrf_token" name="customer[_csrf_token]" value="0136dba17fc1a81dc2c3b44dcb513712" />
...
<a onClick="document.myForm.submit();">Send</a>
</form>
site.html:
<iframe id="myFrame" name="myFrame" src="form.php" frameborder="0" >foo</iframe>
index.html:
<html>
<head></head>
<frameset rows='100%,*'>
<frame name='target' src='site.html'>
<noframes>foo</noframes>
</frameset>
</html>
I also tried to submit the form with these calls:
$('#myForm').submit();
document.forms['myForm'].submit();
parent.frames['myFrame'].document.forms['myForm'].submit();
<input type="submit" value="send" name="send" id="send" />
Can you help me?
EDIT:
I found the problem. I use the symfony framework. symfony uses a hidden csrf token in combination with a cookie value to secure the form trasmission. For some reason in my case IE8 is not able to store this cookie. Now I removed the csrf token from the form to get it working correctly.
CSRF was not the main problem. The problem in my case was caused by the IE security settings. IE does not allow a.o. cookies from domains with an underscore in it.
My domain was foo_bar.dev.domain.com, after chaning it to foo-bar.dev.domain.com it worked, also with enabled CSRF.
When I submit a form using method "POST" and full canvas callback Url action inside Facebook iframe canvas, I cannot get the form elements in the request.
Can anyone give me some help on this?
page code:
<form action="http://apps.facebook.com/myapp" method="post" target="_top">
<input type="hidden" name="myvar" value="v" />
<input type="submit" />
</form>
If i understood your question i think that
you are in an IFRAME... so why use a facebook url for the action?
simply put in the action parameter the url of your web application (not the facebook url, but the url of the canvas) something like http://www.yourhost.it/your_fb_app/process.php/aspx
hope this help (and hope to have understood your problem)
