PHP DOCTRINE DBAL pagination

The goal

Everyone faces the task when it's required to get list of items by customizable filters, to sort by customizable parameters and paginate these items. This library helps to do it.

Usage

GETTING STARTED

Examples work with table users (id, is_active, name, created_at).

At first create your builder. It's necessary to define base query there:

<?php

namespace Foo\Bar;

use Ifedko\DoctrineDbalPagination\ListBuilder;

class MyListBuilder extends ListBuilder
{
	protected function baseQuery()
	{
	    $builder = $this->getQueryBuilder();
        $builder
            ->select(['u.id, u.name, u.created_at'])
            ->from('users', 'u')
            ->where('u.is_active IS TRUE');

        return $queryBuilder;
	}
}

Then use the builder:

<?php

namespace Foo\Bar;

use Ifedko\DoctrineDbalPagination\ListPagination;
use Foo\Bar\MyListBuilder;

$dbConnection = \Doctrine\DBAL\DriverManager::getConnection(['url' => 'mysql://dbuser:dbpasswd@127.0.0.1/dbname']);
$limit = 10;
$offset = 20;
$parameters = [];

$listBuilder = new MyListBuilder(
	$dbConnection
);
$listBuilder->configure($parameters);

$listPagination = new ListPagination($listBuilder);
$listPage = $listPagination->get($limit, $offset);

where

$limit is a count of items on page (20 by default)

$offset is a number of start row (0 by default)

FILTERING

Add configureFilters method to your MyListBuilder class to use customizable filtering.

This examples explains how to turn on filters by certain fields: id, name, created_at

...

protected function configureFilters($parameters)
{
    $mapAvailableFilterByParameter = [
        'id' => new EqualFilter('id', \PDO::PARAM_INT),
        'name' => new EqualFilter('name', \PDO::PARAM_STR),
        'created_at_from' => new GreaterThanOrEqualFilter('user.created_at'),
        'created_at_to' => new LessThanOrEqualFilter('user.created_at')
    ];

    /* @var $filter FilterInterface */
    foreach ($mapAvailableFilterByParameter as $parameterName => $filter) {
        if (isset($parameters[$parameterName])) {
            $filter->bindValues($parameters[$parameterName]);
            $this->filters[] = $filter;
        }
    }

    return $this;
}
...

where

parameters is array which can contain parameters for filter (see using the builder above)

EqualFilter, GreaterThanOrEqualFilter and LessThanOrEqualFilter are some of available filters (see below about all filters)

For example,

$parameters = [
    'id' => 1,
    'title' => 'name'
];

SORTING

Add configureSorting method to your MyListBuilder class:

...
use Ifedko\DoctrineDbalPagination\Sorting\ByColumn;

...

protected function configureSorting($parameters)
{
    $this->sortUsing(new ByColumn('id', 'user_id'), $parameters);
    $this->sortUsing(new ByColumn('name', 'name'), $parameters);
    $this->sortUsing(new ByColumn('from', 'user.created_at'), $parameters);
    $this->sortUsing(new ByColumn('to', 'user.created_at'), $parameters);

    return $this;
}
...

where

parameters is array which can contain parameters for sorting (see using the builder above)

For example,

$parameters = [
    'sortBy' => 'name',
    'orderBy' => 'DESC'
];

FILTERS

• DateRangeFilter
• EqualFilter
• GreaterThanOrEqualFilter
• LessThanOrEqualFilter
• LikeFilter
• MultipleEqualFilter
• MultipleLikeFilter

MultipleLikeFilter

This filter supports complex search queries, like substrings separated by a space. It narrows results when more search words is provided. Also negotiation is possible, like '-word'.

example:

search: bla results (3):

search: bla fi results (2):

search: bla fi -final results (1):

Options

It is possible to define the options:

• operator - comparison operator, ILIKE, for example
• matchFromStart - array of columns to do match from start of the string, col like 'substring%' for example
