inspector [inˈspektər] - noun - an official employed to ensure that official regulations are obeyed.
Inspector is your validations handler for PHP applications. Inspector is easy to use and easy to learn and imposes rules on the payload supplied.
<?php
// Example payload that is
$data = array(
"username" => "simon",
"email" => "[email protected]",
"password" => "secret",
"password_confirmation" => "secret"
);
// Create a new instance of inspector
$inspector = new Inspector($data);
// Ensure that the data is valid
$inspector->ensure("username")
->isAlpha("is not only alpha characters")
->isMin(3, "is to short")
->isMax(10, "is to long");
$inspector->ensure("email")
->isValidEmail("is not valid")
->notNull("is empty");
$inspector->ensure("password")
->isSame("password_confirmation", "don't correspond")
->isMin(6, "is to short");
// Check if any errors exist
echo $inspector->hasErrors(); // Returns false
// Throw a exception if there are errors
$inspector->validate(); // Returns false<?php
// Example payload that is valid
$data = array(
"username" => "s",
"email" => "simon@--",
"password" => "s",
"password_confirmation" => "b"
);
// Create a new instance of inspector
$inspector = new Inspector($data);
// Ensure that the data is valid
$inspector->ensure("username")
->isAlpha("is not only alpha characters")
->isMin(3, "is to short")
->isMax(10, "is to long");
$inspector->ensure("email")
->isValidEmail("is not valid")
->notNull("can not be empty");
$inspector->ensure("password")
->isSame("password_confirmation", "don't correspond")
->isMin(6, "is to short");
echo $inspector->hasErrors(); // Returns true
print_r($inspector->errors());
/*
Array
(
[username] => Array
(
[0] => is to short
)
[email] => Array
(
[0] => is not valid
)
[password] => Array
(
[0] => don't correspond
[1] => is to short
)
)
*/
// If you like you can throw an InspectorException
$inspector->validate(); // InspectorExceptionInspector comes loaded with a few default validators.
isNull() / notNull() - Check if payload is null
isMax($int) / notMax($int) - Check length of string
isMin($int) / notMin($int) - Check length of string
isFloat() / notFloat() - Check if payload is a float
isInt() / notInt() - Check if payload is a int
isUrl() / notUrl() - Check if payload is a URL
isEmail() / notEmail() - Check if payload is a e-mail
isIp() / notIp() - Check if payload is a valid ip
isAlnum() / notAlnum() - Check if payload is alphanumeric
contains($needle) / notContains($needle) - Check if $needle exists in payload
isSameAs($needle) / notSameAs($needle) - Check if $needle is exactly the same as payload
isRegex($regex) / notRegex($regex) - Check if $regex matches payload
isChars($chars) / notChars($chars) - Check if $chars exist inside string
It's easy to add your own validators to Inspector. Below I added a
validator to check if the payload contains ninja. You don't need to
specify is/not when you add validators, they gets added
magically. Also notice the number of arguments, $str is the string
getting tested. The error message argument is added automagically. There
is a small ceavat when doing it this way. You can't create validators
with optional arguments.
<?php
Inspector::addValidator("ninja", function($str) {
return strpos($str, "ninja") !== false;
});
$inspector = new Inspector(array(
"name" => "Inspector 'ninja' Gadget",
"email" => "inspector.gadget@localhost"
));
// Check that "ninja" is present
$inspector->ensure("name")->isNinja("ninja is missing");
// Check that "ninja" is present (same as isNinja)
$inspector->ensure("name")->ninja("ninja is missing");
// Check that "ninja" is not present
$inspector->ensure("email")->notNinja("ninja is present");
$inspector->hasErrors(); // FalseCopyright (c) 2011 Simon Gate [email protected]
