    <p>Sorry if this seems pretty dumb but simple but I can't seem to figure out why I am getting these errors: </p> <p>Warning: mysql_result() expects parameter 1 to be resource, boolean given in C:\Program Files (x86)\EasyPHP-5.3.9\www\Image Upload\func\user.func.php on line 25</p> <p>Notice: Undefined index: user_id in C:\Program Files (x86)\EasyPHP-5.3.9\www\Image Upload\register.php on line 37</p> <p>Here is the code for each file</p> <p>user.func.php:</p> <pre><code>function user_exists($email){ $email = mysql_real_escape_string($email); $query = mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = `$email`"); return (mysql_result($query, 0) == 1) ? true : false; } </code></pre> <p>and here is register.php:</p> <pre><code>if (isset($_POST['register_email'], $_POST['register_name'], $_POST['register_password'])){ $register_email = $_POST['register_email']; $register_name = $_POST['register_name']; $register_password = $_POST['register_password']; $errors = array(); if(empty($register_email) || empty($register_name) || empty($register_password)){ $errors[] = 'All fields must be filled out'; } else{ if(filter_var($register_email, FILTER_VALIDATE_EMAIL) === false){ $errors[] = 'Email address not valid'; } if(strlen($register_email) &gt; 255 || strlen($register_name) &gt; 35 || strlen($register_password) &gt; 35){ $errors[] = 'One or more fields contains too many characters'; } if(user_exists($register_email) === true){ $errors[] = 'That email has already been registered to another user'; } } if(!empty($errors)){ foreach ($errors as $error){ echo $error, '&lt;br /&gt;'; } } else { $register = user_register($register_email, $register_name, $register_password); $SESSION['user_id'] = $register; echo $_SESSION['user_id']; } } </code></pre> <p>Thanks for any help! -TechGuy24</p>

    1. COIt helps when you post an error message that lists line numbers if you identify which lines those numbers match. A simple comment like `this is line 37' at the end of the line would be enough; it saves people the trouble of trying to locate exactly *where* the error is and lets them figure out *what* the error is instead. :-)

    2. COIs there a reason you're doing all of this by hand? A framework like [CakePHP](http://cakephp.org/) or [CodeIgnighter](http://codeignighter.com/) can do a lot of this for you automatically. What you seem to be re-inventing is an extremely application-specific implementation of the [model with basic validations](http://book.cakephp.org/1.3/view/1143/Data-Validation) pattern.

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.
