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 validation
Psecio/Validation
This library seeks to be a simple and reusable validation library for input based on rules.
Example
Messages
You can also define custom messages for the failures using the third $messages parameter on the execute method. The key names on the array match to the value name + check type. For example:
In the example above, we define a custom message for the alpha check on the foo value. If that check were to fail, the error message output would be the new custom message instead of the default.
Getting Errors
There are two method available to get the errors when the result of the execute method is false:
- The
errorsmethod that will return a nested key/value set of failure messages (top level is the value name with each check failure message under it) - The
errorArraymethod that will return a flattended set of messages useful for output to a page without requiring too much looping
Checks
Here is a listing of the check types that Validation supports:
alpha
Checks for only alpha characters
alphanum
Checks for only alpha-numeric characters
numeric
Checks to ensure the value provided is numeric (integer, float, etc)
integer
Checks for integer-only values. Can also include minimum and maximum values:
boolean
Checks for boolean values (true, false, 0, 1 and strings '0', '1')
array
Checks to ensure the value provided is an array
length
Checks the value to ensure the (string) length matches requirements. You must provide a minimum value, but a maximum can also be defined
date
Checks to be sure the value given is a date (as parsed by strtotime)
before
Checks to see if the value (a parseable date) is before the date provided (as parsed by strtotime)
after
Checks to see if the value (a parseable date) is after the date provided (as parsed by strtotime)
in
Checks to ensure the value provided is in a set of values
json
Checks to be sure the value is a valid JSON formatted string (using json_decode)
required
Checks to be sure the value exists
ip
Checks to ensure the value provided is a valid IPv4 or IPv6 formatted address
Check to ensure the value provided is a validly formatted email address
regex
Check to ensure the value matches a certain regular expression at least once
equals
This check can be used to see if the values of two fields match exactly.
callback
This check can be used to call custom logic via a static class method. For example, if your class is:
Then your rule would look something like this:
And the check method should return a boolean result.
