Basic form validation in PHP

Usage

1. Include the class located in FormValidate/Form.class.php wherever you need the PHP form validator.

2. Create the rules array for your existing form:

$rules = [];
$rules["input_name"] = [
    "required" => true,
    "minlength" => 3,
    "maxlength" => 100,
    "alphabetical" => true,
    "label" => "name",
    ];

Existing rule keys are:

• required boolean - If set to true, the field must not be empty when submitting the form
• empty boolean - If set to true, the field must be empty when submitting the form
• minlength integer - Sets a minimal length for the field value
• maxlength integer - Sets a maximal length for the field value
• alphabetical boolean - If set to true, the field must only include alpabetical letters (a-z or A-Z), have a minimal length of 2 and may contain spaces
• number boolean - If set to true, the field value must be numeric
• email boolean - If set to true, the field value must match an email address. FILTER_VALIDATE_EMAIL is used for validation
• phone boolean - If set to true, the field value must match a phone number with a length between 3 to 18 characters. The characters can include a + in the beginning -, space or parantheses (( and )).
• label string - Sets the label contained in the error message

1. Initialize the form validator with the $_POST data and the created rules:

use FormValidate\Form;
$Form = new Form($_POST, $rules);

1. $Form->validate() returns true if the validation has been successfully done. If errors occur during the validation, $Form->getErrors() will return an array with at least one entry.
