zFilters

a simple package to filter your Laravel models without repetitive loops or various if-else

Installation

You can install the package via composer:

composer require kayckmatias/z-filters

Usage

You just need two things: make a new filter and create a scope in your model to point filter.

To make a new Filter:

php artisan make:zfilter NameFilter

Example:

and configure your filter options according to your preference (read here)

Now, is need make a scope in your model, example:

public function scopeFilterBy(Builder $query, array $filters)
{
    $filter = new UsersFilter($query, $filters);

    return $filter->apply();
}

Configure

zFilters supports three filters type: simple, relation and complex.

Simple Filters:

Simple Filter is a whereIn condition, when you make a simple filter you is saying.

'custom_name' => 'column to verify set whereIn'

Let's assume that your user table has the column "department_id", to make a simple filter you just need to reference how the name of the filter option will be, let's call it "departments" and the column, which would be "department_id"

'departaments' => 'departament_id'

Now the array of values or single value you send in $filters['departments'] will be filtered in whereIn condition on the simple filter

Relation Filters:

Relation Filter is a whereIn condition in a relation, when you make a relation filter you is saying.

'custom_name' => ['relation' => 'column to verify set whereIn']

Let's assume that your User model has the relation with department (departments()), to create a relationship filter where we must get all the users that the department belongs to manager 1 or 2 we can do this:

'departments_manager' => ['departments' => 'manager_id']

Now the array of values or single value you send in $filters['departments_manager'] will be filtered in whereIn condition in departments relation on manager_id column.

Complex Filters

The complex filter can deal with more specific conditions, it accepts a callback function and you can filter however you want, let's go to another example. Assuming your same user table has a name column and a summary column and you expect to do a complex search for both conditions by value, one way to do it would be:

'search' => function ($q, $filterValue) {
    $q->where(function ($q) use ($filterValue) {
        $q->where('name', 'LIKE', "%" . $filterValue . "%");
        $q->orWhere('summary', 'LIKE', "%" . $filterValue . "%");
    });
}

The complex filter option named 'search' will execute the function, the value of $q will be the query builder being formed and the second parameter, $filterValue will be automatically implemented to what is sent in $filters['search'], as it is a callback function you can work on it too, manipulate the values sent, as if it were inside the query builder itself.
