I have collection form and need to access the value to show in my view. The problem is seems the key variable declared as Integer and I got error like this :
Impossible to access an attribute ("nama") on a integer variable ("0")
in SifoAdminBundle:DftAbsensi:manage.html.twig at line 65
Here my Twig :
{% for key, absensi in form_edit %}
<li>{{ form_edit.vars.value.statusS.key.nama }}</li>
{% endfor %}
If I change {{ form_edit.vars.value.statusS.key.nama }} into {{ form_edit.vars.value.statusS.1.nama }} its works fine.
Here my controller :
/* Show data */
$emShow = $this->getDoctrine()->getManager();
$collectionAbsensi = new CollectionAbsensi();
foreach ($entityGrupPelajar as $temp) {
$entity = new DftAbsensi();
$entity = $emShow->getRepository('SifoAdminBundle:DftAbsensi')->findOneBy(array('idGrupPelajar' => $temp, 'tanggal' => $tanggal));
if ($entity)
{
$entityPelajar = $emShow->getRepository('SifoAdminBundle:MstPelajar')->find($temp->getIdPelajar());
$dftAbsensi = new DftAbsensi();
$dftAbsensi->setId($entity->getId())
->setIdGrupPelajar($entity->getIdGrupPelajar())
->setTanggal($entity->getTanggal())
->setStatus($entity->getStatus())
->setNis($entityPelajar->getNis())
->setNama($entityPelajar->getNama())
;
$collectionAbsensi->getStatusS()->add($dftAbsensi);
}
}
$emShow->flush();
$formEdit = $this->createForm(new CollectionAbsensiType(), $collectionAbsensi);
$formEdit->add('save', 'submit', array('attr' => array('class' => 'btn btn-info')));
return $this->render('SifoAdminBundle:DftAbsensi:manage.html.twig', array(
'form_edit' => $formEdit->createView(),
));
I have searched for this problem also read the issue #902 but still this problems occurs in my Symfony 2.4 on PHP 5.4
Is there any ways to get that value in iteration without key?
Try changing
form_edit.vars.value.statusS.key.nama
To
form_edit.vars.value.statusS[key].nama
The former is equivalent to $form_edit['vars']['value']['statusS']['key']['nama'] (which does not exist) while the latter is equivalent to $form_edit['vars']['value']['statusS'][$key]['nama']

I have a many to many entity relationship, User and Project
The User entity has only one field, the id field since it is extending the FOsUserBundle. I understand that to access the current logged in users by calling the container
$user = $this->container->get('security.context')->getToken()->getUser();
But that's not the case.A project has many users saved in a database.Now I can access it by using a twig loop
users_projects//a many to many table
project_id user_id
3 1
3 2
<td>{% for user in project.users %}{{ user.id}}{% endfor %}</td>
outputs 1,2
The user entity has no getUsername method as it has only one id field.How would you display the username instead of an i.d?
Update
Already solved this.I dont really sure if its the proper way .In ProjectType, I added this
->add('users', 'entity', array(
'class' => 'UserBundle:User',
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('u')
->orderBy('u.username', 'ASC');
},
'expanded' => true,
'multiple' => true
))
With this set up
<td>
{% for user in entity.users %}
{{ user.username }}
{% if not loop.last %},{% endif %}
{% endfor %}
</td>
Now works.Just don't forget to include
use Doctrine\ORM\EntityRepository;
In FormType, else it will throw an error something like
Catchable Fatal Error: Argument 1 passed to.....must be an instance of \EmployeeBundle\Form\EntityRepository, instance of Doctrine\ORM\EntityRepository given
I am using egeloen/ivory-google-map library to show map for each registered user. But in all user list only one map is showing.
This is my method:
public function findCompaniesAction() {
$em = $this->getDoctrine()->getManager();
$companies = $em->createQueryBuilder()
->select('b')
->from('RFQIronilBundle:User', 'b')
->where('b.acc_type = 1')
->getQuery()
->getResult();
foreach ($companies as $key => $company) {
$map = $this->get('ivory_google_map.map');
$map->setMapOption('mapTypeId', MapTypeId::ROADMAP);
$map->setMapOption('mapTypeId', 'roadmap');
$company->map = $map;
}
return $this->render('RFQIronilBundle:Default:find-companies.html.twig', array(
'companies' => $companies
));
}
and in my view I use:
{% for companies in companies %}
{{ google_map_container(companies.map) }}
{{ google_map_js(companies.map) }}
{% endfor %}
All is fine, but map is showing for only first user. What I have missed?
Try giving each map a unique container id. I use something like this:
$map->setHtmlContainerId('map_canvas_'.md5($address));
where $address is a simple address string.
I have 2 entities: Projects and Categories. I have a ManyToMany relation between these two.
The Categories has ManytoOne relation with the entity "industry"
At this moment, there is no direct relation between Projects and industry and I would like to keep this like so, for further search functionality. So in the category table, the list includes categories from all industries.
When I build the form to edit the project (using the form widget), I have a list of checkboxes representing all the categories listed in my category table.
I would like to group the category choices by industry. How can this be done on the form layout only? How can I extract the industry value from the twig widget form data and group the checkboxes by the industry entity?
Thanks Leevi,
I could not find how to implement the suggestion above using both industry and category related entities... I finally found this way of going around the issue, tell me if there is a simpler way, but this works perfect now.
This is my form in the controller
$form = $this->createFormBuilder($project)
->add('categories', 'entity', array(
'class' => 'ACMEProjectBundle:Category',
'property' => 'name',
'expanded' => true,
'multiple' => true,
->getForm();
I also pass to the rendered form the array of industries which has each a list of related categories
$industries = $this->getDoctrine()->getManager()->getRepository('ACMEProjectBundle:Industry')->findall();
In the form.html.twig template
{{ form_errors(form) }}
<form method="post" {{ form_enctype(form) }}>
{% for industry in industries %}
<h4>{{industry.name}}</h4>
<ul class="unstyled">
{% for category in industry.categories %}
{% set key = category.id %}
<li>{{ form_widget(form.categories[key]) }}{{category.name}}</li>
{% endfor %}
</ul>
{% endfor %}
{{form_rest(form)}}
Which gives me the wanted results.
Hopefully this will be enough direction without giving you exact code examples :).
You'll have to setup your form with an expanded, multiple, entity field like so:
<?php
// src/Acme/ProjectBundle/Controller/DefaultController.php
namespace Acme\ProjectBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Acme\ProjectBundle\Entity\Project;
use Symfony\Component\HttpFoundation\Request;
class DefaultController extends Controller
{
public function newAction(Request $request)
{
// create a project and give it some dummy data for this example
$project = new Project();
$form = $this->createFormBuilder($project)
->add('categories', 'entity', array(
'expanded' => true,
'multiple' => true,
'group_by' => 'industry.title'
))
->add('save', 'submit')
->getForm();
return $this->render('AcmeProjectBundle:Default:new.html.twig', array(
'form' => $form->createView(),
));
}
}
The group_by parameter groups the options based on the property path:
See: http://symfony.com/doc/current/reference/forms/types/entity.html#group-by
Now group_by renders a select tag but you should be able to override that with a custom twig theme or manually in the template.
Given the form above you can access the choices in {{ form.categories.vars.choices }} and iterate over them manually.
See: {% block choice_widget_collapsed %} in form_div_layout.html.twig to see how the select box is rendered.
Here's some more information of form theming: http://symfony.com/doc/current/cookbook/form/form_customization.html
I have this function in the controller, that returns a form with a select box. When the values are selected, I retrieve them with
$manifestations = $form['manifestations']->getData();
then put them in a repository function that queries the database $invites = $repository->searchInviteByManif($manifestations);
public function indexAction() {
$entity = new Invite();
$form = $this->createForm(new ManifSearchType(), $entity);
$request = $this->get('request');
$invites = null;
if ($request->getMethod() == 'POST') {
$form->handleRequest($request);
$message = '';
$manifestations = $form['manifestations']->getData();
$repository = $this->getDoctrine()
->getManager()
->getRepository('PrifProtocoleBundle:Invite');
$invites = $repository->searchInviteByManif($manifestations);
$response1 = $this->render('PrifProtocoleBundle:Invite:index.html.twig', array(
'form' => $form->createView(),
'entities' => $invites,
'message' => $message,
));
return $response1;
}
return array(
'form' => $form->createView(),
'entities' => $invites,
);
}
This function then returns a view index.html.twig with a table and all the fields found in the db.
What I want is to export all the queried data $invites in a CSV file, by clicking on a link directly from the HTML table.
So I've put an href="" link in the Twig file,
{% if message is defined %}
<div class="pdf">
<img height="40px" width="40px" src={{ asset('bundles/prifprotocole/images/excel.jpg') }}>
{% for entity in entities %}
<tr class="{{ cycle(['odd', 'even'], loop.index0) }}">
<td>{% if entity.etat == 1 %} Actif {% else %} Inactif {% endif %}</td>
<td>{{ entity.titreGrade }} {{ entity.prenom }} {{ entity.nom }}</td>
<td>{{ entity.fonction }}</td>
This is how I use to export the CSV file without the link :
$response2 = $this->render('PrifProtocoleBundle:Invite:export.csv.twig', array(
'entities' => $invites));
$response2->headers->set('Content-Type', 'text/csv');
$csvfile = $response2->headers->set('Content-Disposition', 'attachment; filename="export.csv"');
return $csvfile;
export.csv.twig file
{% for entity in entities %}
Id {{ entity.id }};
Etat {{ entity.etat }};
Titregrade {{ entity.titreGrade }};
Prenom {{ entity.prenom }};
Nom {{ entity.nom }};
Fonction {{ entity.fonction }};
{% endfor %}
Can someone give me a detailed solution on how to perform this? Much thanks!
You should simply pass the filter criterias, here the $manifestations array as a route parameter, by serializing it first.
Then, you should put a controller like downloadCsvAction() handling this route, querying the $invites from the database, and rendering your export.csv.twig template.
Another option, if you cannot serialize the data in URI, is to create a form with hidden fields containing the data. Then you replace the download link with the submit button of this hidden form.
Guillaume's answer is great if you don't mind fetching your data twice. Once when you display your page, and then when you download the CSV. Another way to do this is to cache the answer. I will give an example using memcache (which is what I use).
First, make sure that memcache is active in your php.ini.
Then before rendering your first page (after fetching the data), cache it:
$key = "csv.$userId";
$memcache = new \Memcache();
$memcache->connect($yourServerHost, $yourServerPort);
$memcache->set($key, json_encode($invites), MEMCACHE_COMPRESSED, 86400); // 24h
The trick is to find a good key, to add your report to the cache, and then be able to retrieve it. It has to be unique. Here, I assume that you have a user that is logged in, and I use the user ID to create a key. If that is not the case, you could create yourself a token, and pass it when rendering the page (along with $invites). This way, you can add the token to the URL to generate the CSV.
Then, in your second action, where you download the CSV, you just fetch the cached data:
$memcache = new \Memcache();
$memcache->connect($yourServerHost, $yourServerPort);
$json = $memcache->get($key);
$invites = json_decode($json , true);
That's it. You should probably create yourself a service for Memcache, so you don't have to create an object, and connect everytime.
I'm trying to create a form which will add a new text box every time the 'Add new box' link got clicked.
I read through the following example.
http://symfony.com/doc/current/reference/forms/types/collection.html
Basically I was following the example from the book. But when the page is rendered and I click on the link nothing happens.
Any thoughts?
Thanks.
This is my controller.
public function createAction() {
$formBuilder = $this->createFormBuilder();
$formBuilder->add('emails', 'collection', array(
// each item in the array will be an "email" field
'type' => 'email',
'prototype' => true,
'allow_add' => true,
// these options are passed to each "email" type
'options' => array(
'required' => false,
'attr' => array('class' => 'email-box')
),
));
$form = $formBuilder->getForm();
return $this->render('AcmeRecordBundle:Form:create.html.twig', array(
'form' => $form->createView(),
));
}
This is the view.
<form action="..." method="POST" {{ form_enctype(form) }}>
{# store the prototype on the data-prototype attribute #}
<ul id="email-fields-list" data-prototype="{{ form_widget(form.emails.get('prototype')) | e }}">
{% for emailField in form.emails %}
<li>
{{ form_errors(emailField) }}
{{ form_widget(emailField) }}
</li>
{% endfor %}
</ul>
Add another email
</form>
<script type="text/javascript">
// keep track of how many email fields have been rendered
var emailCount = '{{ form.emails | length }}';
jQuery(document).ready(function() {
jQuery('#add-another-email').click(function() {
var emailList = jQuery('#email-fields-list');
// grab the prototype template
var newWidget = emailList.attr('data-prototype');
// replace the "$$name$$" used in the id and name of the prototype
// with a number that's unique to our emails
// end name attribute looks like name="contact[emails][2]"
newWidget = newWidget.replace(/\$\$name\$\$/g, emailCount);
emailCount++;
// create a new list element and add it to our list
var newLi = jQuery('<li></li>').html(newWidget);
newLi.appendTo(jQuery('#email-fields-list'));
return false;
});
})
</script>
This problem can be solved by referring to the following link.
https://github.com/beberlei/AcmePizzaBundle
Here you will find the same functionality being implemented.
I've been through this too.
Answer and examples given to this question and the other question I found did not answer my problem either.
Here is how I did it, in some generic manner.
In generic, I mean, Any collection that I add to the form just need to follow the Form template loop (in a macro, for example) and that's all!
Using which convention
HTML is from Twitter Bootstrap 2.0.x
Javascript code is already in a $(document).ready();
Following Symfony 2.0.x tutorial
Using MopaBootstrapBundle
Form Type class
class OrderForm extends AbstractType
{
// ...
public function buildForm(FormBuilder $builder, array $options)
{
// ...
$builder
->add('sharingusers', 'collection', array(
'type' => new UserForm(),
'allow_add' => true,
'allow_delete' => true,
'by_reference' => false,
'required'=> false
));
// ...
}
}
JavaScript
/* In the functions section out of document ready */
/**
* Add a new row in a form Collection
*
* Difference from source is that I use Bootstrap convention
* to get the part we are interrested in, the input tag itself and not
* create a new .collection-field block inside the original.
*
* Source: http://symfony.com/doc/current/cookbook/form/form_collections.html
*/
function addTagForm(collectionHolder, newBtn) {
var prototype = collectionHolder.attr('data-prototype');
var p = prototype.replace(/\$\$name\$\$/g, collectionHolder.children().length);
var newFormFromPrototype = $(p);
var buildup = newFormFromPrototype.find(".controls input");
var collectionField = $('<div class="collection-field"></div>').append(buildup);
newBtn.before(collectionField);
}
/* ********** */
$(document).ready(function(){
/* other initializations */
/**
* Form collection behavior
*
* Inspired, but refactored to be re-usable from Source defined below
*
* Source: http://symfony.com/doc/current/cookbook/form/form_collections.html
*/
var formCollectionObj = $('form .behavior-collection');
if(formCollectionObj.length >= 1){
console.log('run.js: document ready "form .behavior-collection" applied on '+formCollectionObj.length+' elements');
var addTagLink = $('<i class="icon-plus-sign"></i> Add');
var newBtn = $('<div class="collection-add"></div>').append(addTagLink);
formCollectionObj.append(newBtn);
addTagLink.on('click', function(e) {
e.preventDefault();
addTagForm(formCollectionObj, newBtn);
});
}
/* other initializations */
});
The form template
Trick here is that I would have had used the original {{ form_widget(form }} but I needed to add some specific to the view form and I could not make it shorter.
And I tried to edit only the targeted field and found out it was a bit complex
Here is how I did it:
{# All form elements prior to the targeted field #}
<div class="control-collection control-group">
<label class="control-label">{{ form_label(form.sharingusers) }}</label>
<div class="controls behavior-collection" data-prototype="{{ form_widget(form.sharingusers.get('prototype'))|escape }}">
{% for user in form.sharingusers %}
{{ form_row(user) }}
{% endfor %}
</div>
</div>
{{ form_rest(form) }}
