    <p>I'm trying to work with with the PayPal IPN system. I have setup my code to use their SandBox platform for testing. I am looking for a reason as to why the <code>if (strcmp ($res, "VERIFIED") == 0) {</code> parts of my code is NOT executing. Not only that, but none of the part of this code are writing any output to "log.txt".</p> <p>I would appreciate a review of my code to let me know where I am going wrong.</p> <pre><code>&lt;?php require_once('includes/mysql.inc.php'); if($_POST) { $req = 'cmd=' . urlencode('_notify-validate'); foreach ($_POST as $key =&gt; $value) { $value = urlencode(stripslashes($value)); $req .= "&amp;$key=$value"; } // post back to PayPal system to validate $header = "POST /cgi-bin/webscr HTTP/1.0\r\n"; $header .= "Host: sandbox.paypal.com\r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Content-Length: " . strlen($req) . "\r\n\r\n"; $fp = fsockopen ('ssl://sandbox.paypal.com', 443, $errno, $errstr, 30); if (!$fp) { file_put_contents('log.txt', 'httperrrrr'); die(); } else { file_put_contents('log.txt', 'die here'); fputs ($fp, $header . $req); while (!feof($fp)) { $res = fgets ($fp, 1024); $data = print_r($res, TRUE); if (strcmp ($res, "VERIFIED") == 0) { file_put_contents('log.txt', 'verified'); $username = $_POST['custom']; require_once('classes/admin.class.php'); $activate = new Admin($db); $activate-&gt;modifyUser($username, 'activate'); } else { file_put_contents('log.txt', 'noverifyshit'); } } } else { file_put_contents('log.txt', 'no post'); } } ?&gt; </code></pre>

    1. COMaybe it cannot write to the file? Try adding error_reporting(E_ALL); and ini_set('display_errors',1) just before this code you are executing (if you do not already have it anywhere else in your code).

    2. COWell, that actually helped me out a lot. Conditions are running now, just not the one I need to run.... "if (strcmp ($res, "VERIFIED") == 0) {"

    3. COMaybe he result from paypal includes some extra whitespace? The most obvious reason for the comparison failing is simply that the strings are not the same.

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.
