Neos Eel helper for array handling

Installation

composer require punktde/eel-arrayhelper

Usage

This packages provides the methods:

Sort by Key (ksort)

attributes = Neos.Fusion:RawArray
attributes.@process.ksort = ${PunktDe.Array.ksort(value)}

Sort by sub value

  arrayToSort = [
   ['subValueKey' => "bb"]
   ['subValueKey' => "aa"]
  ]
 
  sorted = [
   ['subValueKey' => "aa"]
   ['subValueKey' => "bb"]
  ]

attributes.@process.sortBySubValue = ${PunktDe.Array.sortBySubValue(value, 'subValueKey')}

Filter arrays (array_filter)

attributes.@process.arrayFilter = ${PunktDe.Array.arrayFilter(value)}

Array values (array_values)

attributes.@process.arrayValues = ${PunktDe.Array.arrayValues(value)}

Array flip (array_flip)

attributes.@process.arrayFlip = ${PunktDe.Array.arrayFlip(value)}

Add a key/value pair to an array:

Can be used to add a value with a dynamic key

attributes = Neos.Fusion:RawArray
attributes.@process.addKV = ${PunktDe.Array.setKeyValue(value, 'key', 'value')}

Extract Sub Elements

This method extracts sub elements to the parent level.

@process.extractSubElements = ${PunktDe.Array.extractSubElements(value)}

An input array of type:

[
element1 => [
    0 => 'value1'
],
element2 => [
    0 => 'value2'
    1 => 'value3'
],

will be converted to:

[
    0 => 'value1'
    1 => 'value2'
    2 => 'value3'
]

Group Elements

@process.groupByKey = ${PunktDe.Array.groupByKey(value, 'group')}

Method can be used to convert an array of type

 [
     'element1' => [
          'name' => 'theName1',
          'group' => 'theGroup1',
     ],
     'element2' => [
          'name' => 'theName2',
          'group' => 'theGroup2',
     ],
     'element3' => [
          'name' => 'theName2',
          'group' => 'theGroup2',
     ],
]

into

[
  'theGroup1' => [
     'element1' => [
          'name' => 'theName1',
          'group' => 'theGroup1',
     ],
 ],

 'theGroup2' => [
     'element2' => [
          'name' => 'theName2',
          'group' => 'theGroup2',
     ],
     'element3' => [
          'name' => 'theName2',
          'group' => 'theGroup2',
     ],
   ]
]

Count elements (length)

The method counts elements of a given array or a countable object.

count = ${PunktDe.Array.length(this.rawCollection)}

hasKey(array, key)

bool = ${PunktDe.Array.hasKey(array, key)}

hasValue(array, key)

bool = ${PunktDe.Array.hasValue(array, key)}

getValueByPath(array, path)

Returns the value of a nested array by following the specified path.

result = ${PunktDe.Array.getValueByPath(array, path)}

setValueByPath(subject, path, value)

Sets the given value in a nested array or object by following the specified path.

array = ${PunktDe.Array.setValueByPath(subject, path, value)}

unsetValue(key, array)

Unset the value for the given key

array = ${PunktDe.Array.unsetValue(key, array)}
