Usage
To use this library, you have to create a transformer which needs to extends the AbstractMappingTransformer class.
This Transformer will read mapping and apply it to input data.
Basic example
Transformer
You first have to create your Transformer and implement transform method.
Here we use symfony/yaml ^3.4 to parse a YAML file.
The $result variable now contains the new array.
Configuration
Assuming you got the PHP array $inputArray (input data)
And considering you want to transform it to the following array (expected output)
You will have to implements the following YAML:
Available mapping options
You can declare your node
from: string, the key path of theinputarrayto: string, the key path of theoutputarrayfunction: array, the php function to use to transform the dataname: string, the function's nameparams: [Optional] array, the function's parameters (key paths of theinputarray)
required: boolean, if the key isrequiredcondition: array, the conditions that specify if the key is required or not
Examples
Transform a key a to key b
Get a key b by using a function
Note: Function getB($arg1) must be declared in your related transformer
You can use functions to transform the input value to the expected value.
For example person civility (Mr, Mrs) to numbers (1, 2)
Make a field required
Actually, if from value don't exist in your input array, the to field don't appear in the output array.
If you want this field required, you can add required key.
Use a default value
Actually, if from value doesn't exist in your input array, the to field doesn't appear in the output array.
If you want this field to get a default value, you can add default key.
Add a condition
If you want to transform a field A only if a field B exists.
You can put multiple fields in your condition :
Get all errors mapping at a time
If you want to return all errors at a time you can set the next parameters in config
