Usage
|
|
-----
|
|
|
|
Your data must be an array, it can be form data, a decoded JSON string or whatever.
|
|
Each different validator is a simple standalone class.
|
|
But we use a main class to pass through every validators.
|
|
Let's see a basic example:
|
|
|
|
use SimpleValidator\Validator;
|
|
use SimpleValidator\Validators;
|
|
|
|
$data = array('field1' => '1234');
|
|
|
|
$v = new Validator($data, array(
|
|
new Validators\Required('field1', 'field1 is required'),
|
|
new Validators\Integer('field1', 'field1 must be an integer'),
|
|
));
|
|
|
|
// Validation error
|
|
if (! $v->execute()) {
|
|
|
|
print_r($v->getErrors()); // Get all validation errors
|
|
}
|
|
|
|
|
|
Validators
|
|
----------
|
|
|
|
### Alphanumeric
|
|
|
|
Allow only letters and digits.
|
|
|
|
new Validators\AlphaNumeric('column name', 'error message');
|
|
|
|
### Email
|
|
|
|
I use the same validation method as Firefox: <http://hg.mozilla.org/mozilla-central/file/cf5da681d577/content/html/content/src/nsHTMLInputElement.cpp#l3967>
|
|
|
|
So email address like toto+titi@domain.tld are allowed.
|
|
|
|
new Validators\Email($field, $error_message);
|
|
|
|
### Integer
|
|
|
|
Allow only integer, but also strings with digits only.
|
|
|
|
new Validators\Integer($field, $error_message);
|
|
|
|
### Length
|
|
|
|
Allow only strings with a correct length.
|
|
|
|
new Validators\AlphaLength($field, $error_message, $min, $max);
|
|
|
|
### Numeric
|
|
|
|
Allow float, integer and strings with only digits and dot.
|
|
|
|
new Validators\Numeric($field, $error_message);
|
|
|
|
### Range
|
|
|
|
Allow only numbers inside the specified range.
|
|
|
|
new Validators\Range($field, $error_message, $min, $max);
|
|
|
|
### Required
|
|
|
|
The specified field must exists.
|
|
|
|
new Validators\Required($field, $error_message);
|
|
|
|
### Unique
|
|
|
|
Check inside a database if the column value is unique or not.
|
|
|
|
new Validators\Unique($field, $error_message, PDO $pdo, $table, $primary_key = 'id');
|
|
|
|
`$pdo` must be an PDO instance, `$table` is the table name and by default the primary key is "id".
|
|
If the primary key value is not null, we don't check the uniqueness of the column for this row.
|
|
It's useful if you perform validation for an update.
