Question: How to upload an image from my webserver to facebook via FB API? I'm writing an application that retrieves images from the user's photo album, makes some modifications (e.g. adding a watermark) then send it back to photo album. The code I use to upload the photo is as follows <pre><code><?php include_once("api/facebook.php"); include_once("config.php"); include_once("utils.php"); include_once("bemyfans.php"); $facebook=new Facebook($api_key,$app_secret); $facebook->require_frame(); $user=$facebook->require_login(); echo "Hello <fb:name useyou='false' uid=\"$user\"/>"; $args = array( 'api_key' => $api_key, 'call_id'=>microtime(true), 'v'=>'1.0', 'format' => 'JSON' ); $args['Lenna.png']="@/home/thoai/htdocs/apps/bemyfans/Lenna.png"; signRequest($args,$secret); $ch = curl_init(); $url = 'http://api.facebook.com/restserver.php?method=photos.upload'; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $args); if ($data = curl_exec($ch)) echo "done"; echo $data; function signRequest(&$args, $secret){ ksort($args); $sig = ''; foreach($args as $k => $v){ $sig .= $k . '=' . $v; } $sig .= $secret; $args['sig'] = md5($sig); } ?> </code></pre> It just doesn't work. More specifically, I keep getting an "Incorrect signature" message. What's wrong with the code???

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
