is there a way to get the current route {placeholder} value in symfony?
I have :
/**
* #Route("/ideas/{page}",
* defaults={"page":1},
* requirements={"page":"^\d+$"},
* name="ideas")
*/
public function ideasAction($page) {
.....
return $this->render('idea/idea.html.twig', ["ideas" => $ideas]);
}
And in my twig I want to do something like this :
>
Is it possible?
Like Gara said :
With {{ app.request.get('page') + 1 }} you can get your placeholder
So this works :
{% set page = app.request.get('page') + 1 %}

I am trying to sort of reverse engineer to this twig template to get back to where the the variables are being set in the first place so I can add more variables. This is a Drupal8 project. The beginning of the twig template "node--course.html.twig" is seen below. Its where I see the variables being set.
{#
/**
* #file
* Default theme implementation to display a node.
*
* Available variables:
* - node: Full node entity.
* - id: The node ID.
* - bundle: The type of the node, for example, "page" or "article".
* - authorid: The user ID of the node author.
* - createdtime: Time the node was published formatted in Unix timestamp.
* - changedtime: Time the node was changed formatted in Unix timestamp.
* - label: The title of the node.
* - content: All node items. Use {{ content }} to print them all,
* or print a subset such as {{ content.field_example }}. Use
* {{ content|without('field_example') }} to temporarily suppress the printing
* of a given child element.
* - author_picture: The node author user entity, rendered using the "compact"
* view mode.
* - metadata: Metadata for this node.
* - date: Themed creation date field.
* - author_name: Themed author name field.
* - url: Direct URL of the current node.
* - display_submitted: Whether submission information should be displayed.
* - attributes: HTML attributes for the containing element.
* The attributes.class element may contain one or more of the following
* classes:
* - node: The current template type (also known as a "theming hook").
* - node--type-[type]: The current node type. For example, if the node is an
* "Article" it would result in "node--type-article". Note that the machine
* name will often be in a short form of the human readable label.
* - node--view-mode-[view_mode]: The View Mode of the node; for example, a
* teaser would result in: "node--view-mode-teaser", and
* full: "node--view-mode-full".
* The following are controlled through the node publishing options.
* - node--promoted: Appears on nodes promoted to the front page.
* - node--sticky: Appears on nodes ordered above other non-sticky nodes in
* teaser listings.
* - node--unpublished: Appears on unpublished nodes visible only to site
* admins.
* - title_attributes: Same as attributes, except applied to the main title
* tag that appears in the template.
* - content_attributes: Same as attributes, except applied to the main
* content tag that appears in the template.
* - author_attributes: Same as attributes, except applied to the author of
* the node tag that appears in the template.
* - title_prefix: Additional output populated by modules, intended to be
* displayed in front of the main title tag that appears in the template.
* - title_suffix: Additional output populated by modules, intended to be
* displayed after the main title tag that appears in the template.
* - view_mode: View mode; for example, "teaser" or "full".
* - teaser: Flag for the teaser state. Will be true if view_mode is 'teaser'.
* - page: Flag for the full page state. Will be true if view_mode is 'full'.
* - readmore: Flag for more state. Will be true if the teaser content of the
* node cannot hold the main body content.
* - logged_in: Flag for authenticated user status. Will be true when the
* current user is a logged-in member.
* - is_admin: Flag for admin user status. Will be true when the current user
* is an administrator.
*
* #see template_preprocess_node()
*
* #todo Remove the id attribute (or make it a class), because if that gets
* rendered twice on a page this is invalid CSS for example: two lists
* in different view modes.
*
* #ingroup themeable
*/
#}
{# {{ kint() }} #}
<article id="node-{{ node.id }}" {{ attributes }}>
{{node}}
{{ title_prefix }}
{% if not page %}
<h2{{ title_attributes }}>
{{ label }}
</h2>
{% endif %}
{{ title_suffix }}
{% if node.field_packaging.value == '1' %}
{% set image = content.field_image %}
{% set ce = content.field_tax_credit_hours %}
{% set goal = content.field_goal %}
{% set target_audience = content.field_audience %}
{% set objectives = content.field_objectives %}
{% set accreditation = content.field_accreditation %}
{% set disclosure = content.field_disclosure_statement %}
{# {% set references_old = content.field_references %} #}
{% set references = content.field_references_par %}
{% set appendix = content.field_appendix %}
{% set faculty = content.field_faculty %}
{% set related_courses = content.field_related_courses %}
{# set suggested_courses = content.field_suggested_courses #}
{% set additional = content.field_callout %}
{% set expiration = node.field_expiration.value %}
I have tried taking words that appear to be unique like
field_tax_credit_hours
And search the project to see maybe where its being set but it only appears in other twig files. I also looked at the whole page as a whole to see maybe I can search for where the output is coming from. For example they very start of my page begins with:
<!-- returning result -->
When I search that it points me to a php function called getResult()
public function getResult() {
if ($this->rowBase() == "") {
print "<!-- rowBase empty -->";
\Drupal\Core\Database\Database::setActiveConnection();
return false;
}
print "<!-- returning result -->";
$result = $this->connection->query($this->rowBase())->fetchAll();
\Drupal\Core\Database\Database::setActiveConnection();
return $result;
}
searching for rowBase() i found this function:
public function rowBase() {
if (parent::accessCheck()) {
$sql = "SELECT * FROM learning_courseuser
WHERE idUser = " . $_SESSION['public_area_idst'] .
" AND idCourse = " . $this->ID. " ";
return $sql;
} else {
return "";
}
}
So it appears to not set the variables I need but instead returns the users info if the are logged in. So I am now stuck and don't really know where to go from here. I have been a PHP developer for a year or so and only did a team treehouse drupal course so it was very basic.
I noticed the page also returns this
<!-- BEGIN OUTPUT from 'themes/custom/site/templates/node--course.html.twig' -->
But searching for the string "BEGIN OUTPUT" returns nothing. So I don't know where to go from here.
It seems that the variables are coming from the "content" object but searching content in the project has WAY too many results to go through. Any ideas where to look would be fantastic.
UPDATE
I was asked to look into template_preprocess_node
and got this:
function site_preprocess_node(&$variables) {
$node = \Drupal::routeMatch()->getParameter('node');
if ($node && $node->getType() == 'course') {
$noti = new FormaNotification();
print "HERE";
print_r($noti->getResult());
exit;
if ($noti->getResult()) {
$variables['signIn'] = "yes";
if ($noti->getFormaAdmin())
$variables['is_forma_admin'] = "yes";
else
$variables['is_forma_admin'] = "no";
} else {
$variables['signIn'] = "no";
$variables['is_forma_admin'] = "no";
}
$current_url = Url::fromRoute('<current>');
$variables['signURL'] = 'http://' . $_SERVER['HTTP_HOST'] . $current_url->toString();
if ($node->get('field_packaging')->getValue()[0]['value'] == '2') {
$variables['regis'] = true;
} else {
$reg = new FormaRegis();
$reg->setConnection('docebo');
$reg->setID($node->get('field_docebo_course_id')->getValue()[0]['value']);
$result = $reg->getResult();
if(!empty($result)) {
$variables['regis'] = true;
} else {
$variables['regis'] = false;
}
}
} // course
}
So looking at it, it appears to have some function of registration sign in and not the variables
The answer is into CMS.
The machine name starting with field_* usually is made when you create a new field into a content type on CMS.
Login into cms (/user) and search for structure-> content types -> (your content types) and then manage fields.
You should find it.
I'm having a hell of a time trying to get classes on my body element in D8. I'm using a custom theme and the code I have so far looks like this:
themename.theme
use Drupal\Component\Utility\Html;
/**
* Preprocess variables for html templates.
*/
function HOOK_preprocess_html(&$variables) {
$path_class = !$variables['root_path'] ? 'path-frontpage' : 'path-' . Html::getClass($variables['root_path']);
if (isset($path_class)) {
$variables['attributes']['class'][] = $path_class;
}
}
html.html.twig
{%
set body_classes = [
not root_path ? 'path-frontpage' : 'path-' ~ root_path|clean_class,
]
%}
<body{{ attributes.addClass(body_classes) }}>
I get classes on my body element, but the NID is empty, reading, 'page-node' where I need it to read, 'page-node-NID'.
You have to replace HOOK with the name of your theme mytheme_preprocess_html otherwise Drupal will not call the hook.
I have a route like this:
/**
* #Route("/admin/user/edit/{id}", defaults={"id" = 0}, name="admin_user_edit")
* #Route("/admin/user/edit")
*
*/
public function editAction(Request $request, $id = 0){
(...)
And then a Twig template, where I list all users:
{% for user in users %}
<li>
<a href='{{ path('admin_user_edit'),{'id' : user.getId()} }}'>
{{ user.getUsername() }}
</a>
</li>
{% endfor %}
As you can see I'm trying to pass the 'user.getId()' as an id. And I get this:
Unexpected token "punctuation" of value "," ("end of print statement"
expected) in admin/users/list.html.twig at line 5.
I know it's about this user.getId() because everything was fine before I added this piece of code.
So how can I pass a function result to this "path" function?
Your path function should have the route name and the parameters within the parenthesis like
{{ path('admin_user_edit', {'id' : user.getId() }) }}
Also, as you aren't using arguments in your user.getId() call you can just use user.id instead.
I have a url : http://localhost:8888/projects/oop/2
I want to access the first segment --> projects
I've tried
<?php echo $segment1 = Request::segment(1); ?>
I see nothing print out in my view when I refresh my page.
Any helps / suggestions will be much appreciated
Try this
{{ Request::segment(1) }}
BASED ON LARAVEL 5.7 & ABOVE
To get all segments of current URL:
$current_uri = request()->segments();
To get segment posts from http://example.com/users/posts/latest/
NOTE: Segments are an array that starts at index 0. The first element of array starts after the TLD part of the url. So in the above url, segment(0) will be users and segment(1) will be posts.
//get segment 0
$segment_users = request()->segment(0); //returns 'users'
//get segment 1
$segment_posts = request()->segment(1); //returns 'posts'
You may have noted that the segment method only works with the current URL ( url()->current() ). So I designed a method to work with previous URL too by cloning the segment() method:
public function index()
{
$prev_uri_segments = $this->prev_segments(url()->previous());
}
/**
* Get all of the segments for the previous uri.
*
* #return array
*/
public function prev_segments($uri)
{
$segments = explode('/', str_replace(''.url('').'', '', $uri));
return array_values(array_filter($segments, function ($value) {
return $value !== '';
}));
}
The double curly brackets are processed via Blade -- not just plain PHP. This syntax basically echos the calculated value.
{{ Request::segment(1) }}
Here is how one can do it via the global request helper function.
{{ request()->segment(1) }}
Note: request() returns the object of the Request class.
An easy way to get the first or last segment, in case you are unsure of the path length.
$segments = request()->segments();
$last = end($segments);
$first = reset($segments);
Here is code you can get url segment.
{{ Request::segment(1) }}
If you don't want the data to be escaped then use {!! !!} else use {{ }}.
{!! Request::segment(1) !!}

I import the Bundle AliDatatableBundle on github following the doc step one by one except the part $ bin/vendor install in the installation because with Symfony2.6, there's no need to do this.
When I create the function in my controller, and the rendering in my twig, I have this error:
An exception has been thrown during the rendering of a template ("No
instance found for datatable, you should set a datatable id in your
action with "setDatatableId" using the id from your view ") in
MySpaceGestionPatrimoinesBundle:Batiments:indexBatiments.html.twig at
line 37.
Here's the code for the controller:
/**
* set datatable configs
*
* #return \Ali\DatatableBundle\Util\Datatable
*/
private function _datatable()
{
$controller_instance = $this;
return $this->get('datatable')
->setDatatableId('batiments')
//->setEntity("MySpaceDatabaseBundle:Batiments", "b")
// replace "XXXMyBundle:Entity" by your entity
->setFields(
array(
"Nom" => 'b.nom',
// Declaration for fields:
"Reférence" => 'b.referencebatiment',
// "label" => "alias.field_attribute_for_dql"
"Ensembles" => 'b.ensembles',
"_identifier_" => 'b.id')
// you have to put the identifier field without label. Do not replace the "_identifier_"
)
//->setWhere(
// set your dql where statement
//'x.address = :address',
//array('address' => 'Paris')
//)
//->setOrder("x.created", "desc")
// it's also possible to set the default order
->setHasAction(true);
// you can disable action column from here by setting "false".
}
/**
* Grid action
* #return Response
*/
public function gridAction()
{
return $this->_datatable()->execute();
// call the "execute" method in your grid action
}
/**
* Lists all entities.
* #return Response
*/
public function indexAction()
{
$this->_datatable();
// call the datatable config initializer
return $this->render('MySpaceGestionPatrimoinesBundle:Batiments:indexBatiments.html.twig');
// replace "XXXMyBundle:Module:index.html.twig" by yours
}
And then the code for my twig:
{% extends "MySpaceWelcomeBundle::layout.html.twig" %}
{% block content %}
<div class="jumbotron">
<h4><u>Rechercher un bâtiment et ses affectations spécifiques:</u></h4>
<br>
<div>
{{ datatable({
'id' : 'batiments',
'js' : {
'sAjaxSource' : path('mySpace_formulaire_recherche_batiments')
}
})
}}
</div>
</div>
{% endblock %}
I really don't understand, someone could help me to fix this?
I have already clear the cache, install assets and took over again from the beginning the doc, I do not understand.
Thank you in advance.
It seems like everything was good. I can't see the problem here, if you followed the doc of aliBundle. Try using the Jquery datatable here, the installation is easier I think and better for your project if it's to manage your entities in Symfony.
If you have questions for Jquery DataTables, don't hesitate to ask, I'm using it for a Symfony project too.
