Iterate through all pages and output in a single html file - drupal

I need to output a node (ID 2334) including sub-nodes into a single document to print them later.
How can I load all sub-nodes and output them beneath the main node?
Update
I'm using Drupal 8.
I want to combine all subsites for a given node into a single page.
By sub-nodes / sub-sites I'm referring to the navigation tree.
The key goal is to have a printable version of a whole website section.
Like a category where it combines all related articles into one page.
Update 2
I created a custom page controller and managed to get an array of "sub-nodes":
$subnodes = [];
$tree = \Drupal::menuTree()->load('internal', new \Drupal\Core\Menu\MenuTreeParameters());
foreach ($tree as $item) {
if ($item->link->getRouteParameters()['node'] == $node) {
foreach($item->subtree as $subitem) {
$subnodes[] = $subitem->link->getRouteParameters()['node'];
}
}
}
var_dump($subnodes); // array of ids
I'm now wondering how render the given nodes?

I managed to solve it with a custom controller:
public function exportAll($node) {
$node = (int)$node;
if ($node < 1) {
throw new NotFoundHttpException($node . 'not available');
}
$subnodes = [$node];
$tree = \Drupal::menuTree()->load('internal', new \Drupal\Core\Menu\MenuTreeParameters());
foreach ($tree as $item) {
if ($item->link->getRouteParameters()['node'] == $node) {
foreach($item->subtree as $subitem) {
$subnodes[] = $subitem->link->getRouteParameters()['node'];
}
}
}
$nodes = \Drupal\node\Entity\Node::loadMultiple($subnodes);
return $build = \Drupal::entityTypeManager()->getViewBuilder('node')->viewMultiple($nodes);
}

How to Save Multiple User Metadata in Database?

I am trying to create a registration form (here) with the help of a free plugin.
There are many elements in the registration form.
In the admin panel, meta keys can be assigned for each element in the plugin interface. So there is such an opportunity.
I'm trying to collect many of the elements on the same meta key by taking advantage of this possibility. In this direction, I gave the common meta key value to the elements I created. For example: info_about_register
So far everything is fine. However, if the form is posted, I can only get the last entry in the usermeta table. So the plugin is not serializing the same meta key data. An array does not occur.
There are many form elements. I want to pull these to the admin panel later. Therefore, I think that defining a separate line for each element will tire the system a lot. I contacted the plugin developers about this issue. However, no response for about 1.5 weeks.
I tried to solve this problem myself and found the codes where the action was taken. I made some changes to these. However, I was not successful. I would be very happy if you guide me.

Update:
Data can be stored as an array with a definition like below. Also, the key values ($all_meta_value[$req_key]) are equal to the id, name values automatically assigned to the HTML elements by the plugin.
Using this, different conditional states can be written.
The following code must be defined in the function.php file in the child theme:
add_action('erf_user_meta_updated','for_new_user_meta_uptated',10);
function for_new_user_meta_uptated($data){
//if the defined meta key (info_about_register) matches
if($m_key == 'info_about_register'){
$all_meta_value[$req_key] = $data;
}
}
add_action('erf_user_created', 'for_new_user_created',10);
function for_new_user_created($id){
//Save the values as a new user meta
add_user_meta($id, 'new_info_about_register', $get_meta_value);
//Remove saved single element user meta.
delete_user_meta($id, 'info_about_register');

Hook to change page title

I want to programmatically alter a page title in Drupal 8 so that it will be hard-coded in the theme file.
I'm attempting to use a hook function to preprocess_page_title, but it seems to not understand what page to change the title on.
Here's what I have so far:
function test_preprocess_page_title(&$variables) {
if (arg(0) == 'node/12') {
$variables['title'] = 'New Title';
}
}
I figured the only way to make this change on one specific page is to set the node argument. Has any one figured out a way to override page title on Drupal?
In your template.theme file add the preprocessor and then override page-title.html.twig in your template folder by printing the variable, like below:
function theme_preprocess_page_title(&$variables) {
$node = \Drupal::request()->attributes->get('node');
$nid = $node->id();
if($nid == '14') {
$variables['subtitle'] = 'Subheading';
}
}
then {{ subtitle }}
Here's the method to preprocess your page :
function yourthemename_preprocess_page(&$variables) {
$node = \Drupal::routeMatch()->getParameter('node');
if ($node) {
$variables['title'] = $node->getTitle();
}
}
and in your template page.html.twig
{{title}}
There are a couple of solutions to change the page title
On template
/**
* Implements hook_preprocess_HOOK().
*/
function MYMODULE_preprocess_page_title(&$variables) {
if ($YOUR_LOGIC == TRUE) {
$variables['title'] = 'New Title';
}
}
On the node view page
/**
* Implements hook_ENTITY_TYPE_view_alter().
*/
function mymodule_user_view_alter(array &$build, Drupal\Core\Entity\EntityInterface $entity, \Drupal\Core\Entity\Display\EntityViewDisplayInterface $display) {
if ($YOUR_LOGIC == TRUE) {
$build['#title'] = $entity->get('field_display_name')->getString();
}
}
for a sample if you want to change user title
function mymodule_user_view_alter(array &$build, Drupal\Core\Entity\EntityInterface $entity, \Drupal\Core\Entity\Display\EntityViewDisplayInterface $display) {
if ($entity->getEntityTypeId() == 'user') {
$build['#title'] = $entity->get('field_first_name')->getString();
}
}
On Controller or hook_form_alter
if ($YOUR_LOGIC == TRUE) {
$request = \Drupal::request();
if ($route = $request->attributes->get(\Symfony\Cmf\Component\Routing\RouteObjectInterface::ROUTE_OBJECT)) {
$route->setDefault('_title', 'New Title');
}
}
The Page Title is a block in Drupal 8. If you can find the plugin_id of the page title block (which is likely to be page_title_block), then you can override the title directly, with no need to change an existing twig template, using a block preprocessor. Your code may be similar to the following:
function vhs_preprocess_block(&$variables) {
// This example restricts based on the actual URL; you can replace this with any other logic you wish.
$request = \Drupal::request();
$uri = $request->getRequestUri();
if (
isset($variables['elements']['#base_plugin_id']) &&
$variables['elements']['#base_plugin_id'] == 'page_title_block' &&
isset($variables['content']['#title']['#markup']) &&
strpos($uri, '/url-to-match') === 0 // replace with logic that finds the correct page to override
) {
$variables['content']['#title']['#markup'] = 'My Custom Title';
}
}
The example above uses the Drupal request object to grab and compare the actual URL. The initial question asked to match based on the node path; you could get that with something like:
$current_path = \Drupal::service('path.current')->getPath();
Then, in place of the strpos condition above, you could use:
$current_path == 'node/12'
i have changed the page_title block for user/uid to a different custom account field name like this :
function hook_preprocess_block(&$variables) {
$path = \Drupal::request()->getpathInfo();
$arg = explode('/', $path);
if (isset($arg[2]) && $arg[2] == 'user' && isset($arg[3])) {
if (isset($variables['elements']['content']['#type']) && $variables['elements']['content']['#type'] == 'page_title') {
$account = \Drupal\user\Entity\User::load($arg[3]);
if(isset($account) && isset($account->field_mycustomfield->value)){
$variables['content']['#title']['#markup']=$account->field_mycustomfield->value;
}
}
}
}

Silverstripe 3.2: How to make a custom action button in the CMS to create a new Dataobject and populate it from another one

I'm searching for a way to create a custom action button which allows me to make a new DataObject with pre-filled content from another DataObject. As a simple example: When I have an email and click the "answer"-button in my email-client, I get a new window with pre-filled content from the email before. I need exactly this functionality for my button. This button should appear next to each DataObject in the GridField.
So I know how to make a button and add it to my GridField (--> https://docs.silverstripe.org/en/3.2/developer_guides/forms/how_tos/create_a_gridfield_actionprovider/) and I know how to go to a new DataObject:
Controller::curr()->redirect($gridField->Link('item/new'));
I also found out that there is a duplicate function for DataObjects:
public function duplicate($doWrite = true) {
$className = $this->class;
$clone = new $className( $this->toMap(), false, $this->model );
$clone->ID = 0;
$clone->invokeWithExtensions('onBeforeDuplicate', $this, $doWrite);
if($doWrite) {
$clone->write();
$this->duplicateManyManyRelations($this, $clone);
}
$clone->invokeWithExtensions('onAfterDuplicate', $this, $doWrite);
return $clone;
}
Perhaps it's easier than I think but at the moment I just don't get how to rewrite this to get what I need. Can somebody give me a hint?
That's for sure not the cleanest solution but I think it should do the trick.
At first let's create the custom gridfield action. Here we will save all accessible records in a session and add a query string to the url so that we'll know which object we want to "clone"
public function getColumnContent($gridField, $record, $columnName) {
if(!$record->canEdit()) return;
$field = GridField_FormAction::create(
$gridField,
'clone'.$record->ID,
'Clone',
'clone',
array('RecordID' => $record->ID)
);
$values = Session::get('ClonedData');
$data = $record->data()->toMap();
if($arr = $values) {
$arr[$record->ID] = $data;
} else {
$arr = array(
$record->ID => $data
);
}
Session::set('ClonedData', $arr);
return $field->Field();
}
public function getActions($gridField) {
return array('clone');
}
public function handleAction(GridField $gridField, $actionName, $arguments, $data) {
if($actionName == 'clone') {
$id = $arguments['RecordID'];
Controller::curr()->redirect($gridField->Link("item/new/?cloneID=$id"));
}
}
after adding this new component to our gridfield,
$gridField->getConfig()->addComponent(new GridFieldCustomAction());
we'll need to bring the data into the new form. To do so, add this code directly above "return $fields" on your getCMSFields function so it will be executed every time we'll open this kind of object.
$values = Session::get('ClonedData');
if($values) {
Session::clear('ClonedData');
$json = json_encode($values);
$fields->push(LiteralField::create('ClonedData', "<div id='cloned-data' style='display:none;'>$json</div>"));
}
At the end we need to bring the content back into the fields. We'll do that with a little bit of javascript so at first you need to create a new script.js file and include it in the ss backend (or just use an existing one).
(function($) {
$('#cloned-data').entwine({
onmatch: function() {
var data = JSON.parse($(this).text()),
id = getParameterByName('cloneID');
if(id && data) {
var obj = data[id];
if(obj) {
$.each(obj, function(i, val) {
$('[name=' + i + ']').val(val);
});
}
}
}
});
// http://stackoverflow.com/questions/901115/how-can-i-get-query-string-values-in-javascript#answer-901144
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
})(jQuery);
And that's it ... quite tricky. Hope it will solve your problem.

SilverStripe convertDataObjectSet is stripping additional properties

I am attempting to add the 'AbsoluteLink' property to each DataObject in a DataList and then convert the list to JSON with JSONDataFormatter::convertDataObjectSet().
I have the following function:
public function json() {
$data = ResourceCentreArticlePage::get()->filter('ShowInMenus', '1')->filter('ShowInSearch', '1')->sort('Created', 'DESC');
$pageArray = new ArrayList();
foreach ($data as $page) {
$page->AbsoluteLink = $page->AbsoluteLink();
$pageArray->push($page);
}
// If I dump out the content of $pageArray here the object has the AbsoluteLink property
$jsonFormatter = new JSONDataFormatter();
$jsonData = $jsonFormatter->convertDataObjectSet($pageArray);
// If I dump out the content of $jsonData here there is no AbsoluteLink property
$this->response->addHeader("Content-type", "application/json");
return $jsonData;
}
The problem:
The AbsoluteLink property is removed after running the $pageArray through the convertDataObjectSet method.
What am I missing?
Using $jsonFormatter->setCustomAddFields(); will help here.
Add the following to the Page class:
public function getMyAbsoluteLink() {
return $this->AbsoluteLink();
}
For example to the Page.php:
class Page extends SiteTree {
public function getMyAbsoluteLink() {
return $this->AbsoluteLink();
}
}
And use that "magic field" like this:
public function json() {
$pages = Page::get()
->filter('ShowInMenus', '1')
->filter('ShowInSearch', '1')
->sort('Created', 'DESC');
$jsonFormatter = new JSONDataFormatter();
// add your custom field
$jsonFormatter->setCustomAddFields(["MyAbsoluteLink"]);
$jsonData = $jsonFormatter->convertDataObjectSet(
$pages
);
return $jsonData;
}
Note the $jsonFormatter->setCustomAddFields(["MyAbsoluteLink"]); and I removed the array manipulation.
Also I removed your array manipulation. How the convertDataobjectSet function works it seems you can't amend the objects before it runs.

SilverStripe Inheriting elements from a parent dataobject

I have set a field called Colour in Page.php and for any child I would like to grab the parent colour or loop through till it finds a parent that does have the colour field set.
I have a function below which seems to work in 2.4 but I cannot get to work in SS3 which I call inside a loop in templates as $Inherited(Colour).
Your help is appreciated
public function Inherited($objName) {
$page = $this->owner->Data();
do {
if ($obj = $page->obj($objName)) {
if ($obj instanceof ComponentSet) {
if ($obj->Count()) {
return $obj;
}
} elseif ($obj instanceof DataObject) {
if ($obj->exists()) {
return $obj;
}
} elseif ($obj->exists()) {
return $obj;
}
}
} while ($page->ParentID != 0 && $page = $page->Parent());
}
Assuming your Colour field is a database field and not a relationship to another data object, add the following method to your Page class.
public function getColour() {
// Try returning banners for this page
$colour = $this->getField('Colour');
if ( $colour ) {
return $colour;
}
// No colour for this page? Loop through the parents.
$parent = $this->Parent();
if ( $parent->ID ) {
return $parent->getColour();
}
// Still need a fallback position (handled by template)
return null;
}
If colour is a related data object you could do much the same thing but use the getComponent or getComponents method in place of getField in the code above. This should work on both Silverstripe version 2.4.x and 3.0.x.
This kind of operation, although useful, should probably be done sparingly or be heavily cached as it's recursive could conceivably happen on the majority of page loads, and change very infrequently.
i suppose you've had this function defined inside some DataObjectDecorator, as you're using $this->owner to refer to the current page.
there is no more DataObjectDecorator in SilverStripe 3 (see http://www.robertclarkson.net/2012/06/dataextension-class-replacing-dataobjectdecorator-silverstripe-3-0/) so there are two possible solutions:
a) replace DataObjectDecorator by DataExtension
b) simply move the Inherited function to your Page class, and replace $this->owner by $this
