Nova Field Default Filter Macro

Nova Field Default Filter Macro is a custom macro for Laravel Nova that simplifies the process of setting default values and enabling filtering capabilities for fields.

Requirements

• "php": "^7.3|^8.0"
• "laravel/nova": "^4.0"

Installation

You can install this package via Composer:

composer require javii-script/default-value-filterable

Usage

To use this macro, simply call the defaultFilterable method on a Nova field. Here's an example of how to use it

use Laravel\Nova\Fields\Field;

Field::macro('defaultFilterable', function ($callback, callable $filterableCallback = null) {
    $this->withMeta(['defaultValueCallback' => $callback]);
    $this->filterable($filterableCallback);
    return $this;
});

This macro makes it easy to define a default value for the filter, enhancing the functionality of your Nova resource.

Example

Text::make('Name')
    ->defaultFilterable(function () {
        return 'John Doe';
    })
    ->sortable(),

In this example, the 'Name' field will have a default value of 'John Doe' when filtering is applied.

Text::make('Name')
    ->defaultFilterable(function () {
        return 'John Doe';
    }, function ($request, $query, $value, $attribute) {
        $query->where($attribute, 'LIKE', "{$value}%");
    })
    ->sortable(),

Additionally, the second argument is a callback function that allows you to customize how the filtering is applied.
