README

Here is a simple Pager for Symfony2, _(*1)

, _(*2)

Why do you need a pager ? Because you have a too many item to display on a page. But there is two possibility : * You want to retreive only items to display. In that case the pager must be able to display those items and create the pager caracteristic * You have already retreived a huge list (from a web service). In that case the pager must display only items of the current page, and also the pager caracteristic, _(*3)

For the first case, my pager can help you to get limit and offset value to allow you to retreive only wanted data., _(*4)

Features

• Twig template support (classic and twitter boostrap template)
• Easy to customize and extend

Installation

Add the namespaces to your autoloader in the app/autoload.php :, _(*5)

``` php
'Rebolon'          => __DIR__.'/../src',
```

Add PaginatorBundle to your application kernel in the app/AppKernel.php :, _(*6)

``` php
new Rebolon\PagerBundle\RebolonPagerBundle(),
```

Sample

All you need is to know how many data the pager may manage (the totalItem). By default the pager has 5 items inside (1 to 5), and manage 15 items in the list that you want to display. So you can use the container to simply use the pager :, _(*7)

``` php
$this->get('rebolon_pager.pager');
```

There is a sample in the default controller with route rebolon/pager/test, _(*8)

You can also configure your own Pager for all your bundle, simply add this to the services.xml of your bundle :, _(*9)

``` xml
<service id="mybundle.pager" class="%rebolon_pager.pager.class%">
    <call method="setContainer">
         <argument type="service" id="service_container" />
    </call>
    <call method="setSuffixName">
         <argument>pagerForWS</argument>
    </call>
    <call method="setItemPerPage">
         <argument>5</argument>
    </call>
    <call method="setMaxPagerItem">
         <argument>3</argument>
    </call>
</service>
```

To get your offset/limit values, use the methods specified in PagerInterface : * first you need to do a count(*) on the list you want to display. Then give the value to the init method of the pager. * use the methods getOffset(), and getItemPerPageParam() to retreive offset and limit values for your query, _(*10)

Inside the template, the pager gives you anything you need to create display your pager : * buildPager will create the pager item list (first/prev/X...Y/next/last). It returns an array of associative array which keys are uri/label/title. * isCurrentPage($pageId) allow you to identity if item your looping into is the currentPage * isToDisplay($itemIndex) allow you to know if an item of the list must be displayed or not Have a look at the PagerTplInterface for others methods., _(*11)

There is few twig template to illustrate the possibility of the pager : * standard is a classic pager * twt-bs is a pager that use bootstrap twitter css framework * test and tewtWithLargeList are used by the demo controller of the bundle. They are samples for first and second case i spoke about at the begining of the README, _(*12)

Have fun with it !, _(*13)
