Example: Alpha

This code validates that the username field contains only alphabetic characters. It first checks a valid username (JohnDoe) and then an invalid one (JohnDoe123).

$validationRules = [
    'username' => 'alpha',
];
$dataToValidate = [
    'username' => 'JohnDoe',
];

$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

$dataToValidate['username'] = 'JohnDoe123';
$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

Example: AlphaNum

This code ensures that the username field contains only alphanumeric characters. It first checks a valid username (JohnDoe123) and then an invalid one (JohnDoe123!).

$validationRules = [
    'username' => 'alpha_num',
];
$dataToValidate = [
    'username' => 'JohnDoe123',
];

$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

$dataToValidate['username'] = 'JohnDoe123!';
$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

Example: Numeric

This code checks that the age field contains numeric values. It first validates a correct numeric value (30) and then an incorrect one (thirty).

$validationRules = [
    'age' => 'numeric',
];
$dataToValidate = [
    'age' => 30,
];

$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

$dataToValidate['age'] = 'thirty';
$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

Example: Boolean

This code ensures that the is_active field contains boolean values. It first checks a valid boolean value (true) and then an invalid one (not_a_boolean).

$validationRules = [
    'is_active' => 'boolean',
];
$dataToValidate = [
    'is_active' => true,
];

$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

$dataToValidate['is_active'] = 'not_a_boolean';
$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

Example: String

This code validates that the name field contains string values. It first checks a valid string (John Doe) and then an invalid one (12345).

$validationRules = [
    'name' => 'string',
];
$dataToValidate = [
    'name' => 'John Doe',
];

$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

$dataToValidate['name'] = 12345;
$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

Example: Required

This code ensures that the name field is required. It first checks a valid non-empty value (John Doe) and then an invalid empty value ('').

$validationRules = [
    'name' => 'required',
];
$dataToValidate = [
    'name' => 'John Doe',
];

$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}

$dataToValidate['name'] = '';
$result = Validator::make($validationRules, $dataToValidate);
if ($result->isFailed()) {
    echo "Validation failed";
} else {
    echo "Validation successful!";
}
