仅在用户单击时运行PHP代码

Question

I have a PHP file in which I have this code:

$descText = $_POST["fname"];
$attachement = array('access_token'=>$fbme['access_token'], 'message' => $descText, 'source' => '@'.realpath($tempFile) );
//$attachement = array('access_token'=>$fbme['access_token'], 'source' => '@'.realpath($tempFile) );
$fb_photo = $facebook->api('me/photos','POST',$attachement);

$FQLQuery = 'SELECT object_id, pid, src_big, link FROM photo WHERE object_id = '.$fb_photo['id'];
$FQLResult = $facebook->api(array( 'method' => 'fql.query', 'query' => $FQLQuery, 'access_token'=>$fbme['access_token'] ));
$targetPhoto = $FQLResult[0];
echo '<center><h1>Image created.</h1><br/><img src="'.$targetPhoto['src_big'].'"/></center><br/>';

How can I run this only when a user clicks on a button or link?

You could use a form HTML tag. This is just an example:

<form method="post" action="yourphpfile.php">
    <input type="text" name="fname" value="your first name?" />
    <input type="submit" value="run" />
</form>
