    <p>I used this hash function for a while (got it from the internet). The thing is it used to work immediately but now it is complaining about a paramter. The following is the code:</p> <pre><code>function generateHash($plainText, $salt = null) { if ($salt === null) { $salt = substr(md5(uniqid(rand(), true)), 0, SALT_LENGTH); } else { $salt = substr($salt, 0, SALT_LENGTH); } return $salt . sha1($salt . $plainText); } </code></pre> <p>So I would use this code in the method call:</p> <pre><code>validateUserInput($userid, $pass); </code></pre> <p>and validateUserInput is:</p> <pre><code>function validateUserInput($username, $password) { //$username = mysql_real_escape_string($username); //$password = mysql_real_escape_string($password); if(!$username || !$password) { //$errors['credentials'] = 'Missing Credentials!'; //$_SESSION['errors_array'] = $errors; //echo $errors['credentials']; header("LOCATION:XXXXXXX.php"); } $local_salt = generateHash($password); //echo $local_salt; $groupid; if($username != null &amp;&amp; $password !=null) { connectToServer(); $result = mysql_query("SELECT * FROM users WHERE hashkey = '{$local_salt}'"); while($row_access = mysql_fetch_array($result)) { $groupid = $row_access['groupid']; } if(!isset($result)) { $errors['not_found_user'] = 'No Users Found with Provided Credentials!'; //$_SESSION['errors_array'] = $errors; $userfound = 0; $_SESSION['user_available'] = $userfound; }elseif(isset($result)){ $_SESSION['user_logged'] = array('username' =&gt; $username, 'password' =&gt; $password, 'salt' =&gt; $local_salt, 'groupid' =&gt; $groupid); $userfound = 1; //echo "stored"; $_SESSION['user_available'] = $userfound; } } } </code></pre> <p>finally the error is:</p> <pre><code>Warning: substr() expects parameter 3 to be long, string given in /home/XXXX.php on line 64 </code></pre> <p>This is pointing to the function <code>generateHash()</code></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.
