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 simple-data-mapper
Simple Data Mapper
A lightweight PHP package that implements the Data Mapper pattern to convert raw data into application objects while keeping concerns cleanly separated.
Problem
In a legacy CodeIgniter application with no dependency injection, form handling logic was hard-coded, tightly coupled, and spread across large controllers. Form data structures were difficult to reuse or modify, and there was no clean way to sanitize, clean, or tweak inputs before submission.
What it does
This package allows you to define complete form data as objects and apply any number of transformation functions to clean or modify values before submission. It centralizes form data mapping and processing, improving flexibility and maintainability without requiring changes to the underlying framework.
Collection of objects intended to cut down repetition of code when having to re-map arrays of data with another source (DB field's etc.)
E.g:
if you want to also add validation or additional logic then you would expect to reference the key\value pair again and so on...
Alternatively, we can add a mapping object.
E.g:
While the above seems trivial, let's try and reverse the process. We want to load some data and assign it to our application key ('my-form-field-name').
Additional functionality
You can pass anonymous functions to be triggered when data is loaded in via Mapper::set. The anonymous function must accept a parameter of data and also return it.
- setOnMap() - triggered when mapping data via key
- setOnMapByLookup() - triggered when setting data via lookup key
E.g:
-
setDataFrom()
If the array of data you are mapping contains data you wish to set on a Map but is not referenced by a mapping key or lookup key, you can use the Map::setDataFrom($key).
E.g:
Extend
The Map object can set a few more values that you can use to extend the functionality of Mapper::class.
- setValidation()
- setFormObject()
E.g:
