I am trying to create an form validator class that will check to make sure that people have typed a particular number of characters into specified fields. Here is my page: <pre><code>if ($_SERVER['REQUEST_METHOD'] == 'POST') { require_once('functions.php'); require_once('formValidator.php'); $validator = new FormValidator(); $validator->setFirst($_POST['first']); $validator->setLast($_POST['last']); $validator->setEmail($_POST['email']); $errors = array(); $validator->checkLength($errors); echo $errors; if (!empty($errors)) { echo '' . $message . ''; } } </code></pre> // form here (code above is in PHP tags, of course) Here is my class: <pre><code>class FormValidator { public $first; public $last; public $email; public $fields_with_lengths; public function setFirst($first) { $this->first = $first; } public function setLast($last) { $this->last = $last; } public function setEmail($email) { $this->email = $email; } function setLengths() { $this->fields_with_lengths = array('first' => 2, 'last' => 2, 'email' => 8); } function checkLength($fields_with_lengths) { $length_errors = array(); foreach($fields_with_lengths as $fieldname => $maxlength) { if (strlen(trim($_POST[$fieldname])) > $maxlength) { $length_errors[] = $fieldname; } } if (!empty($length_errors)) { $message = 'There were no errors'; } else { $message = 'There were errors'; } return $message; } } $validator = new FormValidator(); $validator->setFirst($_POST['first']); $validator->setLast($_POST['last']); $validator->setEmail($_POST['email']); </code></pre> Can anyone see what I am doing wrong? I'd be grateful for some help. Thanks.

Guidance

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.
