Detail field display expansion

This feature is used to extend the detail field display, in cases where the built-in display method is not sufficient.

First define the extension class:

  1. <?php
  3. namespace App\Admin\Extensions\Show;
  5. use Dcat\Admin\Show\AbstractField;
  7. class UnSerialize extends AbstractField
  8. {
  9.     // Setting this property to false will not escape the HTML code
  10.     public $escape = false;
  12.     public function render($arg = '')
  13.     {
  14.         // Returns any content that can be rendered
  15.         return unserialize($this->value);
  16.     }
  17. }

Then register the extension class in app/Admin/bootstrap.php

  1. use Dcat\Admin\Show\Field;
  2. use App\Admin\Extensions\Show\UnSerialize;
  4. Field::extend('unserialize', UnSerialize::class);

Then use this extension in the controller

  1. $show->column()->unserialize('xxx');

Parameters passed into the unserialize() method are passed sequentially into the UnSerialize::render() method.

Several common attributes can be found in the parent class Dcat\Admin\Show\AbstractField

  1. /**
  2.  * Field value.
  3.  *
  4.  * @var mixed
  5.  */
  6. protected $value;
  8. /**
  9.  * Current field model.
  10.  *
  11.  * @var Fluent
  12.  */
  13. protected $model;
  15. /**
  16.  * If this field show with a border.
  17.  *
  18.  * @var bool
  19.  */
  20. public $border = true;
  22. /**
  23.  * If this field show escaped contents.
  24.  *
  25.  * @var bool
  26.  */
  27. public $escape = true;

Where $value and $model are the current field value and the current details of the data, in the render() method can be used to get the data you want.

$border is used to control whether the current display needs a border, $escape is used to set the current display to not HTML escape.
