    <p>i have login with my own code at php, now i dont so good at jquery ajax and so on, my login using ajax jquery type json , i take all vals and post them to server side php which check all details , and response answer via the same jquery ajax .</p> <p>the problem is i added nonce token that maded in php to the login form and every time after user try to login the nonce change , the problem is only when i refresh the login page the nonce changed to the good nonce else its will keep the same nonce token and will send with the post not the updated one because the ajax didnt refresh the page after login .</p> <p>So the question is how i trigger the ajax to refresh the nonce token after every response ? the nonce token is write in php.</p> <p>and more thing about the hash nonce token , its make that hash string sometime:</p> <p>asdaskjn34kj+sdf/sd=</p> <p>now the ajax jquery auto remove the '+' from the hash string so its send wrong token in the POST, here my hash function :</p> <pre><code>public static function RandomBytes($count, $printable=FALSE) { $bytes = ''; // supress warnings when open_basedir restricts access to /dev/urand if(@is_readable('/dev/urandom') &amp;&amp; ($hRand = @fopen('/dev/urandom', 'rb')) !== FALSE) { $bytes = fread($hRand, $count); fclose($hRand); } if((strlen($bytes) &lt; $count) &amp;&amp; function_exists('mcrypt_create_iv')) { // Use MCRYPT_RAND on Windows hosts with PHP &lt; 5.3.7, otherwise use MCRYPT_DEV_URANDOM // (http://bugs.php.net/55169). if ((version_compare(PHP_VERSION, '5.3.7', '&lt;') &amp;&amp; strncasecmp(PHP_OS, 'WIN', 3) == 0)) $bytes = mcrypt_create_iv($count, MCRYPT_RAND); else $bytes = mcrypt_create_iv($count, MCRYPT_DEV_URANDOM); } if((strlen($bytes) &lt; $count) &amp;&amp; function_exists('openssl_random_pseudo_bytes')) // OpenSSL slow on Win { $bytes = openssl_random_pseudo_bytes($count); } if ((strlen($bytes) &lt; $count) &amp;&amp; @class_exists('COM')) { // Officially deprecated in Windows 7 // http://msdn.microsoft.com/en-us/library/aa388182%28v=vs.85%29.aspx try { $CAPI_Util = new COM('CAPICOM.Utilities.1'); if(is_callable(array($CAPI_Util,'GetRandom'))) { $bytes = $CAPI_Util-&gt;GetRandom(16,0); $bytes = base64_decode($bytes); } } catch (Exception $ex) { } } if (strlen($bytes) &lt; $count) { // This fallback here based on phpass code $bytes = ''; $random_state = microtime(); if (function_exists('getmypid')) $random_state .= getmypid(); for ($i = 0; $i &lt; $count; $i += 16) { $random_state = md5(microtime() . $random_state); $bytes .= pack('H*', md5($random_state)); } $bytes = substr($bytes, 0, $count); } if ($printable) return base64_encode($bytes); else return $bytes; } </code></pre> <p>any one know how to change this function to make the strings without '+' in the hashesh?</p>

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.
