Requirements

Laravel 4.X / 5.X / 6.X
laravelcollective/html package if you use Laravel5.X
php 5.5+

Installation

Step 1: Install package using Composer

Add nayjest/grids to "require" section of your composer.json

"require": {
    "nayjest/grids": "^2.0.0"
},

For Laravel 5 you also need to add "laravelcollective/html":

"require": {
    "nayjest/grids": "^2.0.0",
    "laravelcollective/html": "^5"
},

Then install dependencies using following command:

php composer.phar install

Instead of editing composer.json and executing composer install you can just run following command:

For Laravel 4

php composer.phar require nayjest/grids

For Laravel 5 / Laravel 6

php composer.phar require nayjest/grids laravelcollective/html

Step 2: Laravel Setup

Add following line to 'providers' section of app/config/app.php file:

'Nayjest\Grids\ServiceProvider',

For Laravel 5 / 6 you also need to add "illuminate/html" service provider:

'Nayjest\Grids\ServiceProvider',
'Collective\Html\HtmlServiceProvider',

You may also add facade aliases to your application configuration:

    'Form'  => 'Collective\Html\FormFacade',
    'HTML'  => 'Collective\Html\HtmlFacade',
    'Grids'     => 'Nayjest\Grids\Grids',

Code

Usage

Basic example

In example below grid is configured by php array using Nayjest/Builder package facilities.

$cfg = [
    'src' => 'App\User',
    'columns' => [
            'id',
            'name',
            'email',
            'country'
    ]
];
echo Grids::make($cfg);

Results available here. For more details see demo application repository

Advanced example

If you don't like plain arrays, you can construct grids using object oriented api:

Step 1. Instantiate & Configure Grid

See example below

# Let's take a Eloquent query as data provider
# Some params may be predefined, other can be controlled using grid components         
$query = (new User)
    ->newQuery()
    ->with('posts')
    ->where('role', '=', User::ROLE_AUTHOR);


			
# Instantiate & Configure Grid
$grid = new Grid(
    (new GridConfig)
        # Grids name used as html id, caching key, filtering GET params prefix, etc
        # If not specified, unique value based on file name & line of code will be generated
        ->setName('my_report')
        # See all supported data providers in sources
        ->setDataProvider(new EloquentDataProvider($query))
        # Setup caching, value in minutes, turned off in debug mode
        ->setCachingTime(5) 
        # Setup table columns
        ->setColumns([
            # simple results numbering, not related to table PK or any obtained data
            new IdFieldConfig,
            (new FieldConfig)
                ->setName('login')
                # will be displayed in table header
                ->setLabel('Login')
                # That's all what you need for filtering. 
                # It will create controls, process input 
                # and filter results (in case of EloquentDataProvider -- modify SQL query)
                ->addFilter(
                    (new FilterConfig)
                        ->setName('login')
                        ->setOperator(FilterConfig::OPERATOR_LIKE)
                )
                # optional, 
                # use to prettify output in table cell 
                # or print any data located not in results field matching column name
                ->setCallback(function ($val, ObjectDataRow $row) {
                    if ($val) {
                        $icon  = "<span class='glyphicon glyphicon-user'></span>&nbsp;";
                        $user = $row->getSrc();
                        return $icon . HTML::linkRoute('users.profile', $val, [$user->id]);
                    }
                })
                # sorting buttons will be added to header, DB query will be modified
                ->setSortable(true)
            ,
            (new FieldConfig)
                ->setName('status')
                ->setLabel('Status')
                ->addFilter(
                    (new SelectFilterConfig)
                        ->setOptions(User::getStatuses())
                )
            ,
            (new FieldConfig)
                ->setName('country')
                ->setLabel('Country')
                ->addFilter(
                    (new SelectFilterConfig)
                        ->setName('country')
                        ->setOptions(get_countries_list())
                )
            ,
            (new FieldConfig)
                ->setName('registration_date')
                ->setLabel('Registration date')
                ->setSortable(true)
            ,
            (new FieldConfig)
                ->setName('comments_count')
                ->setLabel('Comments')
                ->setSortable(true)
            ,
            (new FieldConfig)
                ->setName('posts_count')
                ->setLabel('Posts')
                ->setSortable(true)
            ,
        ])
        # Setup additional grid components
        ->setComponents([
            # Renders table header (table>thead)
            (new THead)
                # Setup inherited components
                ->setComponents([
                    # Add this if you have filters for automatic placing to this row
                    new FiltersRow,
                    # Row with additional controls
                    (new OneCellRow)
                        ->setComponents([
                            # Control for specifying quantity of records displayed on page
                            (new RecordsPerPage)
                                ->setVariants([
                                    50,
                                    100,
                                    1000
                                ])
                            ,
                            # Control to show/hide rows in table
                            (new ColumnsHider)
                                ->setHiddenByDefault([
                                    'activated_at',
                                    'updated_at',
                                    'registration_ip',
                                ])
                            ,
                            # Submit button for filters. 
                            # Place it anywhere in the grid (grid is rendered inside form by default).
                            (new HtmlTag)
                                ->setTagName('button')
                                ->setAttributes([
                                    'type' => 'submit',
                                    # Some bootstrap classes
                                    'class' => 'btn btn-primary'
                                ])
                                ->setContent('Filter')
                        ])
                        # Components may have some placeholders for rendering children there.
                        ->setRenderSection(THead::SECTION_BEGIN)
                ])
            ,
            # Renders table footer (table>tfoot)
            (new TFoot)
                ->addComponent(
                    # TotalsRow component calculates totals on current page
                    # (max, min, sum, average value, etc)
                    # and renders results as table row.
                    # By default there is a sum.
                    new TotalsRow([
                        'comments',
                        'posts',
                    ])
                )
                ->addComponent(
                    # Renders row containing one cell 
                    # with colspan attribute equal to the table columns count
                    (new OneCellRow)
                        # Pagination control
                        ->addComponent(new Pager)
                )
        ])
);

Step 2. Render Grid

<?php echo $grid->render(); ?>

# Example below will also work as Grid class implements __toString method.
# Note that you can't forward Exceptions through __toString method on account of PHP limitations.
# Therefore you can preliminarily render grid in debug reasons and then pass resutls to view.
<?php echo $grid; ?>

# or shorter
<?= $grid ?>
# or using blade syntax (Laravel 5)
{!! $grid !!}

Notes

Class names in example code used without namespaces therefore you must import it before
Grids does not includes Twitter Bootstrap css/js files to your layout. You need to do it manually Quick links:

<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">

<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap-theme.min.css">

<!-- Latest compiled and minified JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>

Nayjest\Grids\Components\Pager component works only with Laravel 4.X, for Laravel 5 / 6 use Nayjest\Grids\Components\Laravel5\Pager

Working with related Eloquent models

If you need to render data from related Eloquent models, the recommendation is to use joins instead of fetching data from related models becouse in this case filters/sorting will not work. Grids sorting and filters changes Laravel query object, but Laravel makes additional queries to get data for related models, so it's impossible to use filters/sorting with related models.

Following example demonstrates, how to construct grid that displays data from Customer model and related Country model.

// building query with join
$query = Customer
    ::leftJoin('countries', 'customers.country_id', '=','countries.id' )
    ->select('customers.*')
    // Column alias 'country_name' used to avoid naming conflicts, suggest that customers table also has 'name' column.
    ->addSelect('countries.name as country_name')
...  
///   "Country" column config:
	(new FieldConfig)
	        /// Grid column displaying country name must be named according to SQl alias: column_name
		->setName('country_name')
		->setLabel('Country')
		// If you use MySQL, grid filters for column_name in this case may not work,
		// becouse MySQL don't allows to specify column aliases in WHERE SQL section.
		// To fix filtering for aliased columns, you need to override 
		// filtering function to use 'countries.name' in SQL instead of 'country_name'
		->addFilter(
			(new FilterConfig)
				->setOperator(FilterConfig::OPERATOR_EQ)
				->setFilteringFunc(function($val, EloquentDataProvider $provider) {
					$provider->getBuilder()->where('countries.name', '=', $val);
				})
		)
		// Sorting will work by default becouse MySQL allows to use column aliases in ORDER BY SQL section.
		->setSortable(true)
	,
...

Upgrade Guide

From 1.X to 2.X

There are full backward compatibility between 1.X and 2.X branches.

From 0.9.X to 1.X

There are full backward compatibility between 0.9.X and 1.X branches.

From 0.8.X to 0.9.X

Grids starting from v 0.9.0 uses "laravelcollective\html" instead of outdated "illuminate\html".

You may continue to use illuminate\html, but it's recommended to replace it to laravelcollective\html.

Replace illuminate\html to laravelcollective\html in composer.json
Replace class aliases section in config/app.php ('Illuminate\Html\HtmlFacade' to 'Collective\Html\FormFacade' and 'Illuminate\Html\HtmlFacade' to 'Collective\Html\HtmlFacade')
Replace 'Illuminate\Html\HtmlServiceProvider' to 'Collective\Html\HtmlServiceProvider'
Run composer update

From 0.3.X to 0.4.X

Use THead & TFoot instead of Header & Footer components
If you have customized grid view (grid.php), refactor it using changes in default view
Some components became default, so you don't need to add it to configuration

Default components hierarchy:

- GridConfig
    - THead
        - ColumnHeadersRow
        - FiltersRow
    - TFoot
        - OneCellRow
            - Pager

For adding child components to default one, resolve it by name and use addComponent / addComponents methods.

Example:

...
(new GridConfig)
    ->setDataProvider($provider)
    ->getComponentByName(THead::NAME)
        ->getComponentByName(FiltersRow::NAME)
            ->addComponent(
                (new HtmlTag)
                    ->setTagName('button')
                    ->setContent('Filter')
                    ->setAttributes([
                        'type' => 'submit',
                        'class' => 'btn btn-success btn-sm'
                    ])
                    ->setRenderSection('filters_row_column_Actions')
            )
            ->getParent()
        ->getParent()
    ->setColumns([
...

Note that setComponents method rewrites components structure provided by defaults.
