i used this tutorial https://developers.facebook.com/docs/opengraph/tutorial/ to make my first App but i want to use php variable for my og:title like this <meta property="og:title" content="<?php echo $title; ?>" /> . This php variable is changing constantly every time the page loads but when I post my action in the facebook appears with the old title!
Here's the code:
<?php
$title = ' Hello world';
// <---- This php variable is changing every time
the page loads but the title is not being recognised
?>

You need to correct the meta tags definition. Use attribute name, not property:
E.g.:
<meta name="og:title" content="<?php echo $title; ?>" />
You can use the debugger to test your code:
http://developers.facebook.com/tools/debug
Also note that when you click share, the content of your page might be cached. But, the debugger, always gets the latest content.
It appears you are experiencing "freezing" of og:title that Facebook performs after a number of actions – 50 likes, shares and/or comments – were performed with that link.
One of the main reasons why Facebook does this, is to prevent many people sharing a seemingly safe link and then having the site owner replace the title with offensive content and have it display on people's timelines.
For additional information, see this link.

I have a websites displaying cars. if user clicks on each car, it will direct to each car info page. I want to share each car content(image,title,description,url).
For ex.if user clicks on car with id 1,share dialog will display content for that car id 1, and if user clicks on car with id 2,share will display content for car id 2. I have googled for solution but have not found it. Below is my code.
<head>
<meta property="og:url" content="<?php echo 'http://motorcarmyanmar.com';?>" />
<meta property="og:type" content="website" />
<meta property="og:title" content="Buy,Sell,Rent,Or Lease Cars Or Car Accessories In Myanmar" />
<meta property="og:description" content="Car Sales,Car Rentals,Car Accessories Sales" />
<meta property="og:image" content="http://motorcarmyanmar.com/pictures/car1.png" />
<meta property="og:image:alt" content="car picture"/>
<meta property="og:image:width" content="500" />
<meta property="og:image:height" content="400" />
<meta property="fb:app_id" content="1538657022815637" />
</head>
In the beginning of body.
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '1538657022815637',
autoLogAppEvents : true,
xfbml : true,
version : 'v2.8'
});
FB.AppEvents.logPageView();
};
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.8&appId=1538657022815637";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
In the car info page.
<script>
document.getElementById('shareBtn').onclick = function() {
var title,description,image;
title=$('#title_fb').val();
description=$('#description_fb').val();
image=$('#image_fb').val();
FB.ui({
method: 'share_open_graph',
action_type: 'og.shares',
action_properties: JSON.stringify({
object: {
'og:url': window.location.href,
'og:title': title,
'og:description': description + ' Lakhs',
'og:image': image,
'og:image:width':'500',
'og:image:height':'400'
}
})
},
function (response) {
// Action after response
});
}
</script>
With the codes i have given, the dynamic share works. But i want the share image to be bigger not a thumbnail. I read that if share reaches 50 counts,og tags can not be edited. So is there another way to share or is this way right. I saw other website pages sharing dynamic content without creating objects.
Follow Facebookes best practices about pictures sizes: https://developers.facebook.com/docs/sharing/best-practices/#images
Also, you should use a separate URL with a separate og:url tag for each share and just method: 'share' without other parameters. That share_open_graph method is just a workaround.
For example:
<meta property="og:url" content="<?php echo 'http://motorcarmyanmar.com/?id=' . $_GET['id'];?>" />
Of course you need to check if the parameter even exists, but it´s just an example.
The url is
http://www.motorcarmyanmar.com/pages/car_details/ca36?ca36=Details&Details=ca36
<head>
<?php
$title_header="";
$description_header="";
$features_header="";
$image_header="";
if(isset($_GET['Details']))
{
$car_id=$_GET['Details'];
$car_details= //get from database width $car_id;
$title_header=$car_details['header'];
$description_header=$car_details['description'];
$image_header=$car_details['image'];
}
?>
<!-- You can use Open Graph tags to customize link previews.
Learn more: https://developers.facebook.com/docs/sharing/webmasters -->
<meta property="og:url" content="<?php echo 'http://motorcarmyanmar.com' . $_SERVER['REQUEST_URI'];?>" />
<meta property="og:type" content="website" />
<meta property="og:title" content="<?php echo (!empty($title_header)?$title_header:'Some Buy,Sell,Rent');?>" />
<meta property="og:description" content="<?php echo (!empty($description_header)?$description_header:'Car Sales,Car Rentals,Car Accessories Sales');?>" />
<meta property="og:image" content="<?php echo (!empty($image_header)?$image_header:'http://motorcarmyanmar.com/images/icons/car1.jpg');?>" />
<meta property="og:image:alt" content="car picture"/>
<meta property="og:image:width" content="500" />
<meta property="og:image:height" content="400" />
<meta property="fb:app_id" content="1538657022815637" />
</head>
this is what i did. With this code, some pages show right share content(title,description,image),some pages show default homepage share content. But only url is right for each page. Is the code in right direction?
I have tried to follow the sample tutorial of facebook : developers.facebook.com/docs/opengraph/tutorial/#debug

Please tell me whats wrong..
Thanks in advance :)
Your API call is incorrect:
FB.api('/me/abcrecipelist:cook&recipe=http://www.akashbc.com/facebookapp/index.html' ...
Should be
FB.api('/me/abcrecipelist:cook?recipe=http://www.akashbc.com/facebookapp/index.html' ...
I.e. The & should be a ?.
I have a facebook application where the user choose 4 of his friends and then it creates a video (swf) with the pictures of your friends in it (loaded via xml). So I need to share this video on the user timeline. Everything works fine but the video is not embedded in the post on his timeline, there is only a post with the link to the page in it.
The weird thing is, if I post the url directly on my timeline, the video is embedded, but not if the same link is posted via the application.
here is my code called by the share button in js :
function postToFeed() {
var obj = {
method: 'feed',
link: 'https://mysite.com/flash/share-page.php?id=22',
picture: 'https://mysite.com/images/video-preview.jpg',
name: 'Name',
caption: 'Caption',
description: 'Description'
};
function callback(response) {
//some code here
}
FB.ui(obj, callback);
}
and the code in my share-page.php
<?php
$id_inscription = $_GET['id'];
$video_url = 'https://mysite.com/flash/share-page.php?id=22';
$video_preview_image = 'https://mysite.com/images/video-preview.jpg';
?>

Found it, in the javascript you have to add

DOesnt work for me .
Also facebook says ,It is NOT supposed to work By Design .

Please share here your code snippet if you could make it work . I have the meta tags taking care for the secure video Url as well .
I'm trying to implement step two of the Recipe Box Facebook app tutorial. I have followed the instructions in step one to set up my app on Facebook and have uploaded the code pasted below to my server as per the instructions in step two of the tutorial. When I load the web page and click the add-to-timeline link I get a Facebook error stating:
Given URL is not allowed by the Application configuration.
Any insight would be greatly appreciated.

In your app settings, be sure that domain you specify is the same domain as where this code lives. Also in the example code, their <head> tag looked like <head prefix="og: http://ogp.me/ns# og_recipebox: http://ogp.me/ns/apps/YOUR_NAMESPACEx#">. Also you appear to be missing the og: tags in your head section as well.
Here's the example code I just downloaded from their site, did I grab the wrong link? Or are you basing yours on old example code?

All non-English (Lithuanian) elements like š,ė,ž,č and more are displayed as code which doesnt look nice. I added a facebook like button to my wordpress blog, which looks like this:
<iframe src="http://www.facebook.com/plugins/like.php?locale=lt_LT&href=<?php echo urlencode(get_permalink($post->ID)); ?>&layout=standard&show_faces=false&width=450&action=like&colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; position: relative; top: -150px; padding: 0 0 20px 0; overflow:hidden; width:450px; height:60px"></iframe>
You can see that I added locale=lt_LT (I'm from Lithuania)
DOCTYPE:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
Im using this:
<?php
$thumb = get_post_meta($post->ID,'_thumbnail_id',false);
$thumb = wp_get_attachment_image_src($thumb[0], false);
$thumb = $thumb[0];
$default_img = get_bloginfo('stylesheet_directory').'/images/default_icon.jpg';
?>
<?php if(is_single() || is_page()) { ?>
<meta property="og:type" content="article" />
<meta property="og:title" content="<?php single_post_title(''); ?>" />
<meta property="og:description" content="<?php
while(have_posts()):the_post();
$out_excerpt = str_replace(array("\r\n", "\r", "\n"), "", get_the_excerpt());
echo apply_filters('the_excerpt_rss', $out_excerpt);
endwhile; ?>" />
<meta property="og:url" content="<?php the_permalink(); ?>"/>
<meta property="og:image" content="<?php if ( $thumb[0] == null ) { echo $default_img; } else { echo $thumb; } ?>" />
<?php } else { ?>

<meta property="og:image" content="<?php if ( $thumb[0] == null ) { echo $default_img; } else { echo $thumb; } ?>" />
<?php } ?>
Can it be a problem with DOCTYPE or something else?
The language of the button sets when you order a button from http://developers.facebook.com/docs/reference/plugins/like/
the button should have the language according to the user. example
js.src = "/ / connect.facebook.net / es_LA / all.js # xfbml = 1 & appId = 250867014982684";
that line where it says you can modify for your code es_LA language. This is html 5.
ok, for like button, try using fb developer page and get the code for htlm5; instead of iframe. i made like button in spanish some time ago, let me check my code. i'll get baack to you.
