    copied!<p>UPDATE: This question has been answered I have a simple form where users can update their mysql db. I was using <code>mysql_</code> to connect to the database but have learned that pdo is a better way to do this since <code>mysql_</code> is depreciated.</p> <p>Included below is the complete form the OLD way followed by the complete form the new way. The new way produces an error</p> <p>OLD WAY:</p> <pre><code>&lt;?php $host = 'ip_address'; $user = 'user_name'; $password = 'password'; $link = mysql_connect($host, $user, $password); $selected = mysql_select_db('db_name', $link); if(!isset($_POST['text-input'])) ?&gt; &lt;form method="post"&gt; %slice% &lt;input type="submit" value="Submit" /&gt; &lt;/form&gt; %[if !edit]% &lt;?php %[repeat items]% $form_input%id=repeatIndex% = $_POST['element-%id=repeatIndex%'] ; %[endrepeat]% $query = 'INSERT INTO `table_name` (%[repeat items]%%[endif]%%html="Edit Me"%%[if !edit]%,%[endrepeat]%) VALUES (%[repeat items]%"' . $form_input%id=repeatIndex% . '",%[endrepeat]%);'; $query = preg_replace('/,\);/',');',$query); $query = preg_replace('/,\) /',')',$query); mysql_query($query); ?&gt; %[endif]% </code></pre> <p>The NEW Way:</p> <pre><code>&lt;?php db = new PDO('mysql:host=ip_address;dbname=db_name;', 'user_name', 'password'); ?&gt; &lt;form method="post"&gt; %slice% &lt;input type="submit" value="Submit" /&gt; &lt;/form&gt; %[if !edit]% &lt;?php %[repeat items]% $form_input%id=repeatIndex% = $_POST['element-%id=repeatIndex%'] ; %[endrepeat]% $query = 'INSERT INTO `table_name` (%[repeat items]%%[endif]%%html="Edit Me"%%[if !edit]%,%[endrepeat]%) VALUES (%[repeat items]%"' . $form_input%id=repeatIndex% . '",%[endrepeat]%);'; $query = preg_replace('/,\);/',');',$query); $query = preg_replace('/,\) /',')',$query); mysql_query($query); ?&gt; %[endif]% </code></pre> <p>The errors that gets throw is this:</p> <pre><code>Warning: mysql_query() [function.mysql-query]: Access denied for user 'kuler'@'localhost' (using password: NO) in /home/path_to/index.php on line 125 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /home/path_to/index.php on line 125 </code></pre> <p>I hope I have provided enough information.</p>
