I have a problem with displaying data with age who I must calculate with birth_date attribute
Controller
public function listageAction()
{
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
'select DATE_DIFF( CURRENT_DATE(),p.dateNaissance)
from PersonnelBundle:Personnel p'
);
$personnels = $query->getResult();
return $this->render('PersonnelBundle:Default:listage.html.twig');
}
View
{% for personnel in personnels %}
<li> {{ personnel.nomP }} {{ personnel.prenomP }} </li>
<li> {{ personnel.age}} </li>
{% endfor %}
I have this error:
Variable "personnels" does not exist in PersonnelBundle:Default:listage.html.twig at line 6
Your problem is not calculating a date, you haven't injected the $personnels variable into a twig template. Take 5 minutes to read the documentation on views.
http://symfony.com/doc/current/quick_tour/the_view.html
Specifically: this example is relevant to you.
$this->render('default/index.html.twig', array(
'variable_name' => 'variable_value',
));

I use This function to get data
public function UserAction()
{
$easyuser = $this->getDoctrine()->getrepository('AppBundle:User')->findall();
foreach($easyuser as $user){
$id = $user->getid();
$username = $user->getUsername();
$email = $user->getEmail();
$roles = $user->getRoles();
}
return $this->render('easycall/user.html.twig', ['easyuser' => $easyuser, 'roles' => $roles]);
}
and in twig i use this code to show data
{% for entity in easyuser %}
<tr>
<td>{{entity.id}}</td>
<td>{{entity.username}}</td>
<td>{{entity.email}}</td>
{% for role in entity.roles %}
<td>{{role}}</td>
{% endfor %}
</tr>
{% endfor %}
The problem is that i get all the roles if the user is ROLE_SUPER_ADMIN, i want to get only the first value from every array.
i tried something like reset() but it did'nt work, any suggestion??
This is also a picture how the results look likes.
1st item from array shoul be somethink like
{{entity.roles | first}}
but it's simply 1st item from array, i'm not sure if it always be more "powerfull role"
I have this twig code:
<div style="padding-left: 5em" class="comment">
<p>{{ comment.author.name }} - {{ comment.created|date('j. n. Y H:i') }}</p>
<p>{{ comment.text }}</p>
<p>Odpovědět na komentář</p>
{% for child in comment.children %}
{% include 'BlogApplicationBundle:Post:_comment.html.twig' with {'comment' : child}%}
{% endfor %}
</div>
and this is function that processes the output from link in twig code:
/**
* #Route("/post/{id}/newcommentresponse", name="comment_response_new")
* #Template("BlogApplicationBundle:Post:form.html.twig")
*/
public function commentResponceAction($id,$idc)
{
$comment = new Comment();
$form = $this->createForm(new CommentType(), $comment);
return array(
'form' => $form->createView()
);
}
when i try to run code i get this error :
Controller "Cvut\Fit\BiWt1\Blog\ApplicationBundle\Controller\CommentController::commentResponceAction()"
requires that you provide a value for the "$idc" argument (because
there is no default value or because there is a non optional argument
after this one).
So it seems that second argument passsed through link is ignored and i have no idea what am i doing wrong.
You are missing the $idc definition in your #Route annotation. It should look something like this:
#Route("/post/{id}/newcommentresponse/{idc}", name="comment_response_new")
or this:
#Route("/post/{id}/{idc}/newcommentresponse", name="comment_response_new")
You can also leave it out of the route and function declaration and grab it directly from the Controller:
/**
* #Route("/post/{id}/newcommentresponse", name="comment_response_new")
* #Template("BlogApplicationBundle:Post:form.html.twig")
*/
public function commentResponceAction($id)
{
$idc = $request->query->get('idc');
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 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.
Using symfony2 I load some entities and then try to iterate over them in a twig template.
However, instead of the variable content I am getting the following:
Resource id #23
My twig template looks like this:
<ol>
{% for post in posts %}
<li>
<div>
{{ post.content }}
</div>
</li>
{% endfor %}
</ol>
My controller code is:
$repository = $this->getDoctrine()
->getRepository('AppPostBundle:Post');
$reviews = $repository->findBy(
array('title' => 'my title'))
;
Maybe is too late for this answer (definitely it is LOL) but I recently had the same issue and the problem is that blob datatypes are treated as a buffer, so you have to read the info using buffer functions.
In your entity Post code you may add this method:
public function readContent(){
$content = '';
while(!feof($this->getContent())){
$content.= fread($this->getContent(), 1024);
}
rewind($this->getContent());
return $content;
}
Then in your views you may call the readcontent method instead of content:
<ol>
{% for post in posts %}
<li>
<div>
{{ post.readcontent }}
</div>
</li>
{% endfor %}
</ol>
Is better late than never :)
My entity name is : 'Test'
Blob type field is : 'Details'
in '/src/Vendorname/Bundlename/Entity/entityname.php'
**
* Get details
*
* #return string
*/
public function getDetails()
{
return $this->details;
}
/**
* Reading the blob type of content.
* #return data
*/
public function readDetails(){
$details = '';
while(!feof($this->getDetails())){
$details.= fread($this->getDetails(), 1024);
}
rewind($this->getDetails());
return $details;
}
and in '*.html.twig' file
{% for match in matches %}
{{match.readdetails}}
{%endfor%}
