I have a simple module which will return a form , but now i have added this to a menu like
admin/settings/
But i want this form in another page ,so i added a hook_block() , my module showed up in the blocks page and i added it to be seen by all in all pages in content area but i dont get that form ? where did i go wrong ? I am new to drupal any help plz
function emp_form_block($op = 'list', $delta = 0, $edit = array()) {
switch ($op) {
case 'list':
$blocks[0]['info'] = t('New Block');
$blocks[0]['cache'] = BLOCK_NO_CACHE;
return $blocks;
}
}
i am using drupal 6
You should also implement the view op, like this:
case 'view':
return array(
'subject' => t('My awesome form'),
'content' => drupal_get_form('my_awesome_form'),
);
break;

Is it possible to add a button on the basic login form?
function alter_form_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id)
{
if ($form_id == 'user_login_form') {
##ADD BUTTONS ???
$form['#validate'] = ['test_validate'];
$form['actions']['submit']['#submit'][] = 'custom_submit_method';
}
}
You can add a button in the actions wrapper using the following code
$form['actions']['custom_submit'] = [
'#type' => 'submit',
'#name' => 'custom_submit',
'#value' => t('My custom submit button'),
];
If you want to distinct both click, for example if you need to do something else when custom_submit is used, then you will need to access the $form_state->getTriggeringElement(); in your custom_submit_method submission handler.
function custom_submit_method(array $form, FormStateInterface $form_state){
$trigger = $form_state->getTriggeringElement();
if ($trigger['#name'] === 'custom_submit') {
// ...
}
}

I need some help, I've been figuring this for almost an hour and still can't find a way to fix this.
I have a search form to filter data from my CGridView, and I also need a button to view all the records after I finish using search, but I can't figure how to do it. Here's my code for jquery refresh button:
Yii::app()->clientScript->registerScript('initRefresh',<<<JS
$('#refresh-button').on('click',function() {
$('#app-asset-categories-grid').yiiGridView('update');
return false;
});
JS
,CClientScript::POS_READY);
Here's my code for jquery search form:
Yii::app()->clientScript->registerScript('search', "
$('.search-button').click(function(){
$('.search-form').toggle();
return false;
});
$('.search-form form').submit(function(){
$('#app-asset-categories-grid').yiiGridView('update', {
data: $(this).serialize()
});
return false;
});
");
And finally, my grid:
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'id'=>'app-asset-categories-grid',
'columns' => array(
'category_id',
'label',
'description',
'add_date',
'modification_date',
array(
'name'=>'Status',
'filter'=>array('1'=>'Active', '0'=>'Inactive'),
'value'=>'($data->status=="1")?"Active":"Inactive"'
),
array(
'name'=>'Deletion Status',
'filter'=>array('1'=>'Deactivate','0'=>'Active'),
'value'=>'($data->deletion_status=="1")?"Deactivated":"Activated"'
),
array(
'class'=>'CButtonColumn',
),
),
));
I just wanted a refresh button to display all the data again after I use my search form. I need your help guys, thanks.
You need to handle update action in model and set pagination parameter false. An example how to do it:
Add hidden field in search form _search.php
<?php echo CHtml::hiddenField('show_all', 0, array("id"=>"show_all")); ?>
Then handle it in model's search() function (your grid uses it to get data)
like this:
$criteria=new CDbCriteria;
// some criterias
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'pagination' => (isset($_GET["show_all"]) && $_GET["show_all"])?false:array(), // add this line
));
Then set update hidden field when you need it.
$('#refresh-button').on('click',function() {
$('#show_all').val(1); // set it to show all
$('#app-asset-categories-grid').yiiGridView('update');
$('#show_all').val(0); // set to 0 for searching with pagination
return false;
});
Thats it.
I have a module Search in my ZF2 application. The user fills in a search form out and gets a list of courses.
Now I'm adding the pagination to the module. The paginator is basically working: I can retrieve data over it and the pagination is displayed correctly (pagelinks 1-7 for 70 found courses with the dafault setting 10 items per page).
But it's still not usable. When I click on a pagelink, the form POST data is lost. I know -- it cannot work the way, how I implemented it (see the code below). But I have no idea, how to do it correctly, in order to eep checking the form data and nonetheless be able to use pagination.
That is my code:
Table class Search\Model\CourseTable
class CourseTable {
...
// without pagination
// public function findAllByCriteria(CourseSearchInput $input) {
// with pagination
public function findAllByCriteria(CourseSearchInput $input, $pageNumber) {
...
$select = new Select();
$where = new Where();
$having = new Having();
...
// without pagination
// $resultSet = $this->tableGateway->selectWith($select);
// return $resultSet;
// with pagination
$adapter = new \MyNamespqce\Paginator\Adapter\DbSelect($select, $this->tableGateway->getAdapter());
$paginator = new \Zend\Paginator\Paginator($adapter);
$paginator->setCurrentPageNumber($pageNumber);
return $paginator;
}
...
}
Search\Controller\SearchController
class SearchController extends AbstractActionController {
public function searchCoursesAction() {
$form = $this->getServiceLocator()->get('Search\Form\CourseSearchForm');
$request = $this->getRequest();
if ($request->isPost()) {
$courseSearchInput = new CourseSearchInput();
$form->setInputFilter($courseSearchInput->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$courseSearchInput->exchangeArray($form->getData());
// without pagination
// $courses = $this->getCourseTable()->findAllByCriteria($courseSearchInput);
// with pagination
$page = $this->params()->fromRoute('page');
$paginator = $this->getCourseTable()->findAllByCriteria($courseSearchInput, $page);
} else {
$paginator = null;
}
} else {
$paginator = null;
}
return new ViewModel(array(
'form' => $form,
// without pagination
// 'courses' => $courses,
// with pagination
'paginator' => $paginator,
'cities' => ...
));
}
...
}
How to get it working?
I also have the same problem, and I have solved it. But this is not good way. May be the idea will help you.
I solved it as follow: (Search pagination for Zend tutorial album module)
I build two action in controller named "search" and "index".
Whenever the search form submitted, it always post the value to search action. Search action build the url with search parameters, and redirect to index to disply search result.
And when the pagination links clicked, then posted values are passed through url. So whenever index action ask for search parameters, it always get the values in same format.
I defined route as follows:
'album' => array(
'type' => 'segment',
'options' => array(
'route' => '/album[/:action][/:id][/page/:page][/order_by/:order_by][/:order][/search_by/:search_by]',
'constraints' => array(
'action' => '(?!\bpage\b)(?!\border_by\b)(?!\bsearch_by\b)[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
'page' => '[0-9]+',
'order_by' => '[a-zA-Z][a-zA-Z0-9_-]*',
'order' => 'ASC|DESC',
),
'defaults' => array(
'controller' => 'Album\Controller\Album',
'action' => 'index',
),
),
),
There is a parameter named "search_by", which will keep all search parameters as a json string. This is the point, which is not good I know, but have not find any other way yet.
"Search" action build this string as -
public function searchAction()
{
$request = $this->getRequest();
$url = 'index';
if ($request->isPost()) {
$formdata = (array) $request->getPost();
$search_data = array();
foreach ($formdata as $key => $value) {
if ($key != 'submit') {
if (!empty($value)) {
$search_data[$key] = $value;
}
}
}
if (!empty($search_data)) {
$search_by = json_encode($search_data);
$url .= '/search_by/' . $search_by;
}
}
$this->redirect()->toUrl($url);
}
And next index action decode the string, do necessary action, and also send the json string to view.
public function indexAction() {
$searchform = new AlbumSearchForm();
$searchform->get('submit')->setValue('Search');
$select = new Select();
$order_by = $this->params()->fromRoute('order_by') ?
$this->params()->fromRoute('order_by') : 'id';
$order = $this->params()->fromRoute('order') ?
$this->params()->fromRoute('order') : Select::ORDER_ASCENDING;
$page = $this->params()->fromRoute('page') ? (int) $this->params()->fromRoute('page') : 1;
$select->order($order_by . ' ' . $order);
$search_by = $this->params()->fromRoute('search_by') ?
$this->params()->fromRoute('search_by') : '';
$where = new \Zend\Db\Sql\Where();
$formdata = array();
if (!empty($search_by)) {
$formdata = (array) json_decode($search_by);
if (!empty($formdata['artist'])) {
$where->addPredicate(
new \Zend\Db\Sql\Predicate\Like('artist', '%' . $formdata['artist'] . '%')
);
}
if (!empty($formdata['title'])) {
$where->addPredicate(
new \Zend\Db\Sql\Predicate\Like('title', '%' . $formdata['title'] . '%')
);
}
}
if (!empty($where)) {
$select->where($where);
}
$album = $this->getAlbumTable()->fetchAll($select);
$totalRecord = $album->count();
$itemsPerPage = 2;
$album->current();
$paginator = new Paginator(new paginatorIterator($album));
$paginator->setCurrentPageNumber($page)
->setItemCountPerPage($itemsPerPage)
->setPageRange(7);
$searchform->setData($formdata);
return new ViewModel(array(
'search_by' => $search_by,
'order_by' => $order_by,
'order' => $order,
'page' => $page,
'paginator' => $paginator,
'pageAction' => 'album',
'form' => $searchform,
'totalRecord' => $totalRecord
));
}
All the sorting and paging url contain that string.
If you know all the searching paarameters before, then you can define that at route, and pass like the same way without json string. As I have to build a common search, I have build a single string.
Source code for "Album search" is available in git hub at https://github.com/tahmina8765/zf2_search_with_pagination_example.

#Sam & #automatix in the question comments are both right. My suggestion (though I'm looking for a simpler alternative) is to construct a segment route, which covers all of the options that you're likely to need and start with a standard form POST request.
Then, after the request is validated, pass the form data to the paginationControl helper as follows:
$resultsView = new ViewModel(array(
'paginator' => $paginator,
'routeParams' => array_filter($form->getData())
));
Then, in your view template, set the route parameters in the paginationControl view helper:
<?php echo $this->paginationControl($paginator, 'Sliding', 'paginator/default',
array('routeParams' => $routeParams)
) ?>
I've used array_filter here because it's a really simple way of removing any element from the form data that's null, empty or so on. That way you don't pass in extra data that you don't need.
I am using Paul Irish's infinitescroll with masonry js on a wordpress site. It is a site with a lot of content. I want infintescroll to stop adding new content when it reaches post number 40 and to give the "No additional items" message at that point. I tried to customize the wordpress loop to only return 40 posts but that did not seem to work.
I thought that maybe one of the options in infinitecroll might do the trick but the infintescroll documentation is very sparse. For example, there is an infinitescroll option in the "loading" init section called "finished: undefined" Is it possible to change that parameter to stop the scrolling after a certain number of content items?
Is there some other obvious way to control when infinitescroll stops loading new content?
Any assistance would be greatly appreciated.
In the Administration -> Settings -> Reading you can set Blog pages show at most to 40.
With code:
Two ways I've done Masonry by numbers like your question I've had success with the following:
limit posts_per_page in your query arguments
$args = array(
'posts_per_page' => 40,
'offset' => 5,
'orderby' => 'post_date',
'order' => 'DESC',
'exclude' => 'none',
'post_type' => 'post',
'post_status' => 'publish',
'suppress_filters' => true
);
$posts = new WP_Query( $args );
if ( $posts -> have_posts()) {
while ( $posts -> have_posts() ) : $posts->the_post(); {
//do stuff with the posts returned here
}
}
or by incrementing:
$counts = 0 ;
$posts = new WP_Query( $args );
if ( $posts -> have_posts()) {
while ( $posts -> have_posts() ) : $posts->the_post(); {
//do stuff with the posts returned here
$counts = ++;
if($counts == 40) { return }
}
}
I'm trying to create a custom search but getting stuck.
What I want is to have a dropdownbox so the user can choose where to search in.
These options can mean 1 or more content types.
So if he chooses options A, then the search will look in node-type P,Q,R.
But he may not give those results, but only the uid's which will be then themed to gather specific data for that user.
To make it a little bit clearer, Suppose I want to llok for people. The what I'm searching in is 2 content profile types. But ofcourse you dont want to display those as a result, but a nice picture of the user and some data.
I started with creating a form with a textfield and the dropdown box.
Then, in the submit handler, i created the keys and redirected to another pages with those keys as a tail. This page has been defined in the menu hook, just like how search does it.
After that I want to call hook_view to do the actual search by calling node_search, and give back the results.
Unfortunately, it goes wrong. When i click the Search button, it gives me a 404.
But am I on the right track? Is this the way to create a custom search?
Thx for your help.

To be honest, I haven't seen many people implement hook_search. Most just use Views, or, for advanced things, something like Faceted Search.
Did you consider using either for your current project? Why didn't it work?
you could also use a combination of hook_menu for your results, and db_queries with your custom (and optimized so faster) queries.
For example:
search/%/%
where the arguments could be whatever you need, for example the first one for minimum price, the second price to the maximum price, third for minimal bedrooms... Your url would look always like that:
search/200/400/null/3/ ...
I have used a null, but it could be anything that you prefer to consider this field as empty.
Then, from your select form you have just to redirect following the structure of this url and adding the parameters in its correct place.
It is probalby not the most beautiful way of building a url, but using this technique and hook_theme will allow you to have an unlimited flexibility. I can show you a project where we are using this technique and, I think it looks pretty good :-).
Any comment regarding this would be much aprreciated :-).
