FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package validate
Harp Validate
Harp Validate is a validation library. It generates errors for objects based on a predefined assertions.
Quick Example:
Errors
The result of $asserts->getErrors($subject) is actually an Errors object. It's an Iterator that holds all the erorrs and has ->humanize() mehtod to display all the errors.
You can also foreach it and get all the errors separately. Casting it to string calls ->humanize() automatically.
You can also traverse through the Errors object using getFirst and getNext methods.
ValidateTrait
You can also add a special trait to an object to make it "validatable".
It will addd these methods to your class:
| Method | Description |
|---|---|
| validate() | Perform the assertions, specified in the getValidationAsserts(). Will return true or false, and will set the errors object |
| getErrors() | Returns an Errors object. If validate has not been called yet, will return an empty Errors object |
| isEmptyErrors() | Return true or false |
| assertValid() | Throw Harp\Validate\InvalidException if there are any errors |
Available Asserts
Callback
Assert that the result of a given callback is true. You must use a closure object, and will recieve the subject and the value as arguments.
Assert if the value is not a proper email address. uses a small and fast regex which should handle most cases.
EmailStrict
Assert if the value is not a proper email address. Uses a slower but more comprehensive check thane Email.
GreaterThan
Assert that the value is greater than a set length. Value can be int or float or even numeric string
InArray
Assert if the value is present in an array, uses a simple in_array call. Will throw InvalidArgumentException if the array is empty.
IP
Assert that the value's is a valid IP address uses filter_var() internally
IsInstanceOf
Assert if the value is an object of a given class is_a call. Will throw InvalidArgumentException if the class does not exist.
LengthBetween
Assert that the value's string length is between two set lengths (including). Uses mb_strlen() internally.
LengthEquals
Assert that the value is of exact string length. Uses mb_strlen() internally.
LengthGreaterThan
Assert that the value's string length is longer than a set length. Uses mb_strlen() internally.
LengthLessThan
Assert that the value's string length is shorter than a set length. Uses mb_strlen() internally.
LessThan
Assert that the value is less than a set length. Value can be int or float or even numeric string
Matches
Assert that a value of one property matches to the value of another
IsInteger
Assert that the value is a integer number.
IsFloat
Assert that the value is a float number.
Present
Assert if the value is empty
RegEx
Assert that the value matches a given regex. Passed directly to preg_match()
URL
Assert if the value is a valid url. Converts all UTF related charecters in the url to their proper encoding. It also will convert non-ASCII domain names, using "idn" if the "intl" extension is available. This is similar to what browsers normally do.
URLStrict
Assert if the value is a valid url. Uses php's filter_var() method.
AssertsTrait
This trait gives you the ability to easily add assertions to another object.
Here are all the methods added by this trait.
| Method | Description |
|---|---|
| getAsserts() | Get the Asserts object |
| addAssert(AbstractAssertion) | Add arbitrary asserts |
| assertCallback($name, $message) | Add an Assert\Callback object |

| assertLengthBetween($name, $min, $max, $message) | Add an Assert\LengthBetween object |
| assertLengthEquals($name, $length, $message) | Add an Assert\LengthEquals object |
