How to Call a function of Controller From Twig - php

This is my view:
<div class="CSlider">
<div class="CProducts" >
<table>
<tr>
{% for count in 1..result|length %}
<td>
{% block tile %}
{% include 'tile.twig' %}
{% endblock %}
<h1>
{{ result[ count - 1 ].id }}
</h1>
</td>
{% if count is divisible by (6) %}
</tr>
<tr>
{% endif %}
{% endfor %}
</table>
</div>
</div>
And this is my controller:
class COlxMyAdsController extends COlxDatabaseHandler {
protected $view;
public function __construct($container){
parent::__construct($container);
$this->view=$container->view;
}
public function fetchMyLiveAdIdsByUserId( Request $request, Response $response ) {
$args=$request->getParams();
$args=$args['id'];
$results = $this->m_objOlxUserDetails->fetchMyLiveAdIdsByUserId($args);
return $this->view->render($response,'profile.twig',['result' => $results]);
}
}
I want to call a function of the controller from the view. How can I do this using Twig?

Here we can Use Exit_Tags
Through which we can assign a URL to that exit_tag to call this function

Adding a global action in EasyAdmin, place my button underneath the table instead of above

I created a global Action :
public function export(
Admin $user,
StructureRepository $structureRepository,
ExportCsvEntity $exportCsvEntity,
string $entityClass
): HttpFoundationResponse {
$zipcodes = $structureRepository->getZipcodesByStructureFromAdmin($user->getId());
$exportCsvEntity->export(
$zipcodes,
$entityClass
);
return $exportCsvEntity->download($entityClass);
}
public function exportButton(): Action
{
return Action::new('export', 'admin.crud.user.field.activities_tracking.button.export')
->linkToCrudAction('export')
->displayAsLink()
->setCssClass('btn btn-primary')
->createAsGlobalAction()
;
}
Then in my Crud Controller I call it :
if ($this->getUser() instanceof Admin) {
$export = $this->exportAction->exportButton();
$actions->add(Crud::PAGE_INDEX, $export);
}
In the doc its written => Global actions are displayed above the listed entries.
But in my case the button is underneath the table
Have a look here
My template is extending '#!EasyAdmin/crud/index.html.twig'then I override the global_actions block :
{% block global_actions %}
{{ parent() }}
{% endblock global_actions %}
Now my button is above the table but also underneath :
Have a look here
What do I do wrong ?
You are correct when trying to do this by overriding the index template.
An easy way to do this considering how the template is organized is to modify the global_actions block by filtering actions you do not want to show above the list. For example by using a css class to not show a global action above the list.
{% block global_actions %}
<div class="global-actions">
{% for action in global_actions|filter(a => 'under-list' not in a.cssClass) %}
{{ include(action.templatePath, { action: action }, with_context = false) }}
{% endfor %}
</div>
{% endblock global_actions %}
And in your crud controller:
Action::new('customAction', $label, $icon)
->addCssClass('under-list')
->createAsGlobalAction()
->linkToCrudAction('customAction');
And you need to add your new list of actions under your list by overriding the main block.
{% block main %}
{{ parent() }}
{% block under_list_global_actions %}
<div class="under-list-global-actions">
{% for action in global_actions|filter(a => 'under-list' in a.cssClass) %}
{{ include(action.templatePath, { action: action }, with_context = false) }}
{% endfor %}
</div>
{% endblock under_list_global_actions %}
{% endblock main %}
And you should get your custom global action (with the css class under-list) under your list.

Twig not detecting the custom function

I have written a Twig custom function (in a Twig custom extension). I notice the template does not read the function and keeps throwing me the "Method Exists" error.
Was wondering if you have faced this before. Any ideas ?
The custom extension file; $post and $list are both objects:
<?php
namespace App\Twig;
use Twig\Extension\AbstractExtension;
use Twig\TwigFunction;
class ShowContentExtension extends AbstractExtension
{
public function getFunctions()
{
return [
new TwigFunction('ShowList', [$this, 'ShowList']),
new TwigFunction('ShowPost', [$this, 'ShowPost'])
];
}
public function ShowList($list) {
foreach ($list->post as $post) {
$this->ShowPost($post);
}
}
public function ShowPost($post) {
return !((count(array_keys($post->documents))) < 2 && array_key_exists('header', $post->documents));
}
}
and this is where they are being called:
{% if ShowList(list) %}
<h2 >{{ title }}</h2>
<div>
<div>
{% for post in list %}
{% if post|length > 0 %}
{% include ./_links.html.twig' with { 'list': list} %}
{% endif %}
{% endfor %}
</div>
</div>
{% endif %}
and :
{% if ShowPost(post) %}
<div>
<div>
<a href="{{ post.link }}">
<span>{{ post.title }}</span>
</a>
</div>
</div>
{% endif %}
and this is the screenshot of the error :

Symfony 4 user search by email issues

I am trying to implement a search for user by email function into page admin's dashboard. Currently, I have hardcoded a value into $email variable just to test whether the search works. It does find the right user, but does not display anything in the twig.
Executing {{ dump() }} outputs: array:2 [▼ 0 => User {#4745 ▼ -id: 5 -
username: "test_user" -plainPassword: null -password:
"$2y$13$rGYteIrzifg9Dty.O5knOOCHQnzOtF.nZux8h1jc4sNbap5V7Xn0." -email:
"tester#test.com" } "app" => AppVariable {#2617 ▶} ]
the function I use in AdminController.php:
/**
* #Route("/admin/result", name="user_search")
* Method({"POST"})
*/
public function user_search(Request $request)
{
$email = 'tester#test.com';
$result = $this->getDoctrine()
->getRepository(User::class)
->findOneBy(['email' => $email]);
if ($result) {
return $this->render('admin/result.html.twig', $result);
}else{
return $this->render('admin/result.html.twig', [
'error' => 'No user found with this email '.$email]);
}}
result.html.twig:
{% extends 'base.html.twig' %}
{% block body %}
{% if error %}
<span class="error">{{ error }}</span>
{% endif %}
{% if result %}
<table>
<tr>
<th>Username</th><th>Email</th>
</tr>
{% for item in result %}
<tr>
<td>{{ item.getUsername }}</td><td>{{ item.getEmail }}
</td>
</tr>
{% endfor %}
</table>
{% endif %}
{{ dump() }}
{% endblock %}
In twig you assume that the result is an array. For this, uses findBy instead of findOneBy. findBy returns an array of objects with the desired search. The findOneBy return only an object with the desired search or null if results are not found.
Example:
// look for a single User by email
$result = $this->getDoctrine()
->getRepository(User::class)
->findOneBy(['email' => $email]);
// look for multiple User objects matching the email
$result = $this->getDoctrine()
->getRepository(User::class)
->findBy(['email' => $email]);
This was finally solved by these steps:
There was a typo in the hardcoded $email variable.
Changed return $this->render('admin/result.html.twig', 'result'->$result); instead of return $this->render('admin/result.html.twig', $result);
Changed <td>{{ item.username }}</td><td>{{ item.email }}</td> instead of <td>{{ result.getUsername }}</td><td>{{ result.getEmail }}</td>
Check $user with instance
if ($result instanceof User)
.......................................................................
I suggest you use defined in twig
{% if result is defined %}
{% extends 'base.html.twig' %}
{% block body %}
{% if error is defined %}
<span class="error">{{ error }}</span>
{% else %}
<table>
<tr>
<th>Username</th><th>Email</th>
</tr>
{% for item in result %}
<tr>
<td>{{ result.getUsername }}</td><td>{{ result.getEmail }}</td>
</tr>
{% endfor %}
</table>
{% endif %}
{% endblock %}

Why can't I pass this object correctly in Symfony2?

I am following the tutorial from here: https://www.digitalocean.com/community/tutorials/how-to-use-symfony2-to-perform-crud-operations-on-a-vps-part-1
Here is my controller:
public function indexAction()
{
$news = $this->getDoctrine()
->getRepository('FooNewsBundle:News')
->findAll();
if (!$news) {
throw $this->createNotFoundException('No news found');
}
$build['news'] = $news;
return $this->render('FooNewsBundle:Default:news_show_all.html.twig',$build);
}
Here is my view for news_show_all.html.twig
{% block body %}
<table>
{% for new in news %}
<h3>{{ new.Title }}</h3>
{% endfor %}
</table>
{% endblock %}
What I get is a blank page but when viewing source I get this:
<h3></h3>
<h3></h3>
Which is amazing since I have 3 items in my table and it only shows 2 and they are blank. Any ideas?

The show action of Symfony 2 Sonata Admin Bundle is not working

I'm integrating Sonata Admin Bundle into my Symfony 2.6 application by following Symfony 2 jobeet tutorial. Everything is fine except the Show action. I have an entiry "Job" and so I have src/Ibw/JobeetBundle/Admin/JobAdmin.php which have a function configurShowField(ShowMapper $showMapper) like below
<?php
namespace Ibw\JobeetBundle\Admin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Validator\ErrorElement;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Show\ShowMapper;
use Ibw\JobeetBundle\Entity\Job;
class JobAdmin extends Admin
{
// ....
protected function configureShowField(ShowMapper $showMapper)
{
$showMapper
->add('category')
->add('type')
->add('company')
->add('webPath', 'string', array('template' => 'IbwJobeetBundle:JobAdmin:list_image.html.twig'))
->add('url')
->add('position')
->add('location')
->add('description')
->add('how_to_apply')
->add('is_public')
->add('is_activated')
->add('token')
->add('email')
->add('expires_at')
;
}
// ....
}
When I click the Show button and go to the view page (admin/ibw/jobeet/job/xxx/show), it shows none of the fields. The original template processed is /vendor/sonata-project/admin-bundle/Resources/views/CRUD/base_show.html.twig:
{% extends base_template %}
{% block actions %}
<li>{% include 'SonataAdminBundle:Button:edit_button.html.twig' %}</li>
<li>{% include 'SonataAdminBundle:Button:history_button.html.twig' %}</li>
<li>{% include 'SonataAdminBundle:Button:list_button.html.twig' %}</li>
<li>{% include 'SonataAdminBundle:Button:create_button.html.twig' %}</li>
{% endblock %}
{% block tab_menu %}{{ knp_menu_render(admin.sidemenu(action), {'currentClass' : 'active', 'template': admin_pool.getTemplate('tab_menu_template')}, 'twig') }}{% endblock %}
{% block show %}
<div class="sonata-ba-view">
***
{{ sonata_block_render_event('sonata.admin.show.top', { 'admin': admin, 'object': object }) }}
{% for name, view_group in admin.showgroups %}
<table class="table table-bordered">
{% if name %}
<thead>
{% block show_title %}
<tr class="sonata-ba-view-title">
<th colspan="2">
{{ admin.trans(name) }}
</th>
</tr>
{% endblock %}
</thead>
{% endif %}
<tbody>
{% for field_name in view_group.fields %}
{% block show_field %}
<tr class="sonata-ba-view-container">
{% if elements[field_name] is defined %}
{{ elements[field_name]|render_view_element(object) }}
{% endif %}
</tr>
{% endblock %}
{% endfor %}
</tbody>
</table>
{% endfor %}
{{ sonata_block_render_event('sonata.admin.show.bottom', { 'admin': admin, 'object': object }) }}
</div>
{% endblock %}
The inner content of <div class="sonata-ba-view"></div> is not shown except three asterisks I printed. Is there any configuration I'm missing?
You're missing a s in your function's name.
it's
configureShowFields(FormMapper $formMapper)
not
configureShowField(FormMapper $formMapper)
Try to add call in your admin.yml
ibw_jobbeet.admin.jobadmin:
class: Ibw\JobeetBundle\Admin\JobAdmin
...
calls:
- [ setTemplate, ['show', path_to_your_view.html.twig]]
