March 2016 · 4 minute read
Create delete and edit actions for your new page
1. Create Edit action in the pageBundle/Controller/AdminController
/**
* Edit page
*
* @Route("/edit/{id}/", name="PageBundle:Admin:edit")
* @Template("PageBundle:Admin:edit.html.twig")
*/
public function editAction($id, Request $request) {
$em = $this
->getDoctrine()
->getManager();
// Get page
$page = $em
->getRepository('PageBundle:Page')
->findOneById($id);
if ($page === null) {
//Page doesn't exist
throw $this->createNotFoundException();
}
// Check permissions
$this->checkAccess('EDIT', $page);
// Build form
$form = $this->createForm(new PageForm(), $page);
$form->handleRequest($request);
if ($form->isValid()) {
// Form has been posted and is valid – persist to database
$em->persist($page);
$em->flush();
// Log alert message
$this->alert(
'success',
$this->translate(
'admin.edit.success',
array('%name%' => $page->getName()),
'PageBundle'
)
);
// Redirect to self
return $this->redirect(
$this->generateUrl(
'PageBundle:Admin:index'
)
);
}
// Render defined template with this data
return array(
'page' => $page,
'form' => $form->createView(),
);
}
2. Add Controls to the index.html.twig to make edit/delete controls etc on the index page
{% block controls %}
{%
include 'AdminBundle:Utility:controls.html.twig' with {
controls: [
{
class: 'create',
url: path('PageBundle:Admin:create'),
label: 'admin.create.title'|trans,
hasPermission: true
}
]
}
%}
{% endblock controls %}
3. Add into PageBundle/Resources/translations: pages: translations
admin:
index:
title: 'Pages'
pages:
title: "%name%"
create: "Create a new page under '%entity%'"
4. Create an edit.html.twig view in the page bundle
{% extends 'PageBundle:Admin:index.html.twig' %}
{% set domain = 'PageBundle' %}
{% trans_default_domain domain %}
{% block title -%}
{{ 'admin.edit.title'|trans({'%name%': page.name}) }} {{ 'space.title_separator'|trans({}, 'GlobalBundle')|raw }}
{%- endblock title %}
{% block main %}
{{ form_start(form) }}
{{ parent() }}
{{ form_end(form) }}
{% endblock main %}
{% block header %}
<h1>{{ 'admin.edit.title'|trans({'%name%': page.name}) }}</h1>
{% endblock header %}
{% block breadcrumbs %}
{{ parent() }}
<a href="{{ path('PageBundle:Admin:edit', {id: page.id}) }}">{{ 'admin.edit.title'|trans({'%name%': page.name}) }}</a>
{% endblock breadcrumbs %}
{% block content %}
{{ form_widget(form) }}
{% endblock content %}
{% block controls %}
{%
include 'AdminBundle:Utility:controls.html.twig' with {
controls: [
{
class: 'save success',
label: 'admin.edit.submit'|trans
},{
class: 'delete danger',
url: path('PageBundle:Admin:delete', {id: page.id}),
label: 'delete entity'|trans({'%name%': page.name}, 'GlobalBundle'),
hasPermission: is_granted('DELETE', page)
},{
class: 'back',
url: path('PageBundle:Admin:index'),
label: 'admin.back.index'|trans,
hasPermission: is\_granted('VIEW', get\_entity_class('PageBundle:Page'))
}
]
}
%}
{% endblock controls %}
5. Add into PageBundle/Resources/translations: edit: translations

title: 'Edit page %name%'
title_shorts: 'Edit'

{% block alerts %}
{%
include 'GlobalBundle:Utility:alerts.html.twig' with {
classes: ['error', 'warning', 'success', 'info']
}
%}
{% endblock alerts %}
7. Create a template partial in GlobalBundle/views/Utility/ for alerts.html.twig so it can be used anywhere in the app.
{% set alerts = [] %}
{% if classes is not iterable %}
{% set classes = [classes] %}
{% endif %}
{% for class in classes %}
{% set alertSet = app.session.flashbag.get(class) %}
{% if alertSet is not empty %}
{% set alerts = alerts|merge({(class): alertSet}) %}
{% endif %}
{% endfor %}
{% if alerts is not empty %}
<div class="alerts">
{% for class, alertSet in alerts %}
<ul class="{{ class }}">
{% for alert in alertSet %}
<li>

public function deleteAction($id, Request $request) {
$em = $this
->getDoctrine()
->getManager();
//Get page item
$page = $em
->getRepository('PageBundle:Page')
->findOneById($id);
if ($page === null) {
//Page doesn't exist
throw $this->creatNotFoundException();
}
//Check permissions
$this->checkAccess('DELETE', $page);
$form = $this
->createFormBuilder($page)
->getForm();
$form->handleRequest($request);
if ($form->isSubmitted()) {
//Delete empty
$em->remove($page);
$em->flush();

array('%name%' => $page->getName()),
'PageBundle'
)
);
//Redirect to index
return $this->redirect(
