I need to know the simplest method to pass variable from custom module to its template
I have created the custom.module and placed custom.tpl.php in the module folder
function custom_menu(){
$items = array();
$items['custom'] = array(
'title' => t('custom!'),
'page callback' => 'custom_page',
'access arguments' => array('access content'),
'type' => MENU_CALLBACK,
);
return $items;
}
function custom_page() {
$setVar = 'this is custom module';
return theme('custom', $setVar);
}
i have added theme function but it is not working, can any one suggest me what is wrong with this code
function theme_custom($arg) {
return $arg['output'];
}
function custom_theme() {
return array(
'Bluemarine' => array(
'variables' => 'output',
'template' => 'Bluemarine',
),
);
}
You are calling the wrong theme function. Instead of function theme_custom it should be function theme_Bluemarine. You also need to pass an array to the variables piece of hook_theme(). See a simple example here.
Using your example:
function custom_menu(){
$items = array();
$items['custom'] = array(
'title' => t('custom!'),
'page callback' => 'custom_page',
'access arguments' => array('access content'),
'type' => MENU_NORMAL_ITEM,
);
return $items;
}
function custom_page() {
$setVar = 'this is custom module';
return theme('custom', array('output' => $setVar));
}
function custom_theme() {
$path = drupal_get_path('module', 'custom');
return array(
'custom' => array(
'variables' => array('output' => null),
'template' => 'custom',
),
);
}
Now in custom.tpl.php just need <?php print $output; ?>
This works for me:
function custom_menu(){
$items = array();
$items['custom'] = array(
'title' => t('custom!'),
'page callback' => 'custom_page',
'access arguments' => array('access content'),
'type' => MENU_NORMAL_ITEM,
);
return $items;
}
function custom_page() {
$result = db_query('SELECT * from node');
return theme('custom', array('output' => $result));
}
function custom_theme() {
return array(
'custom' => array(
'arguments' => array('output' => NULL),
'template' => 'custom',
),
);
}
function template_preprocess_custom(&$variables) {
}
First, you've to declare you theme and how its behave with the help of hook_theme. After you can easily use the function theme.
Also, maybe you will need to use the hook_preprocess.

I am finally diving in to Drupal 8 for a project. In my module though I can not seem to nail down how to render a template from my module based on the route.
In Drupal 7 I would normally do this
custom.module
function union_views_menu() {
$items = array();
$items['home'] = array(
'title' => 'Home',
'description' => 'home apge',
'page callback' => 'home_page',
'access arguments' => array( 'access content'),
'type' => MENU_CALLBACK
);
return $items;
}
function home_page() {
return theme('home_page');
}
function union_views_theme(){
return array(
'home_page' => array(
'template' => 'templates/home-page'
)
);
}
And then I would have a template in the templates folder
With Drupal 8 I got to about here:
custom.routing.yml
custom:
path: /home
defaults:
_controller: Drupal\custom\Controller\CustomController::custom
requirements:
_permission: 'access content'
src/Controller/CustomController.php
namespace Drupal\custom\Controller;
class CustomController {
public function custom(){
return array(
'#title' => 'Custom Theme',
'#markup' => 'This is a content.'
);
}
}
And all the works great for getting to the route. But I can not seem to figure out creating a hook_theme function for my hook_menu to use as a callback.
Figured it out
Add custom.module
function custom_theme() {
$theme['home_page'] = [
'variables' => ['name' => NULL],
'template' => 'home_page'
];
return $theme;
}
in my controller replaced '#markup' with:
'#theme' => 'home_page'
I am building a custom module which should display a calendar created by a third-part library. So far, so good. The only problem is, the calendar appears on top of page, even above header. It does not seems to be css-related.
This is the way it looks:
This is my module file:
require_once 'includes/apphp-calendar/calendar.class.php';
function calendario_menu(){
$items = array();
$items['eventos/calendario'] = array(
'title' => 'Calendario',
'description' => 'Calendario de Eventos.',
'page callback' => '_page_calendario',
'access callback' => TRUE,
'type' => MENU_CALLBACK,
);
return $items;
}
function _page_calendario() {
$objCalendar = new Calendar();
$calendar = $objCalendar->Show();
return array(
'#markup' => $calendar
);
}
Seems to me like the Show function of the calendar class outputs rather than returning a string.
try this:
function _page_calendario() {
$objCalendar = new Calendar();
ob_start();
$objCalendar->Show();
$calendar = ob_get_contents();
ob_end_clean();
return array(
'#markup' => $calendar
);
}
I wanted to have a textfield in a form that autocompletes from the database. I have been reading the tutorials and trying to get it to work but thus far not much luck. I am farely new to Drupal so I'm mostly unsure what I am doing xD
My code thus far:
function my_module_menu() {
$items = array();
$items['my_module/form'] = array(
'title' => t('Add List'),
'page callback' => 'my_module_form',
'access arguments' => array('access content'),
'description' => t('My form'),
'type' => MENU_CALLBACK,
);
// path with autocomplete function for casters
$items['caster/autocomplete'] = array(
'title' => t('Autocomplete for casters'),
'page callback' => '_caster_autocomplete',
'access arguments' => array('use autocomplete'),
'type' => MENU_CALLBACK
);
return $items;
}
function my_module_form() {
return drupal_get_form('my_module_my_form');
}
function _caster_autocomplete($string) {
$matches = array();
$results = db_select('warnoun', 'w')
->fields('w', array('full_name'))
->condition('full_name', '%' . db_like($string) . '%', 'LIKE')
->execute();
// save the query to matches
foreach ($results as $result) {
$matches[$result->full_name] = check_plain($result->full_name);
}
// Return the result to the form in json
drupal_json_output($matches);
}
function my_module_my_form($form_state) {
$form['points'] = array(
'#type' => 'select',
'#title' => t('Points'),
'#required' => TRUE, // Added
'#options' => array(
0 => t('15'),
1 => t('25'),
2 => t('35'),
3 => t('50'),
),
);
$form['caster'] = array(
'#type' => 'textfield',
'#title' => t('Caster'),
'#maxlength' => 50,
'#autocomplete_path' => 'caster/autocomplete',
'#required' => TRUE,
);
$entries = db_query('SELECT id, short_name FROM factions ORDER BY id ASC');
$options = array();
foreach ($entries as $entry){
$options[$entry->id] = t($entry->short_name);
}
$form['faction'] = array(
'#type' => 'select',
'#title' => t('Faction'),
'#options' => $options,
);
// Simple Submit Button
$form['submit'] = array(
'#type' => 'submit',
'#value' => 'Submit',
'#required' => TRUE, // Added
);
return $form;
}
So basically there is a table called warnoun with a column full_name and it's with that content that I want to autocomplete the textfield caster.
Any idea what I'm missing/doing wrong?

I am actualy trying to implement my first own entity using this tutorial:
http://www.istos.it/en/blog/drupal-entities/drupal-entities-part-3-programming-hello-drupal-entity
So far anything worked fine, but now i ran in some problem I couldnt get fixed.
After creating my new entity, I get redirected to the page "slider/(id)". But it says that the page could not be found. When I try to open the URL manualy I get the same error.
Here is my code:

The problem is here:
$items['slider/%slider'] = array(
Drupal's menu system will look for a function named slider_load(), whereas your entity load function is named he_slider_load(). This causes the router to bail out and throw a 404.
To fix it, simply change that line to
$items['slider/%he_slider'] = array(
And clear your caches.
I'm building a module (my_module) in Drupal 7.
It has some functionality and also will create new content type.
In my_module.install I implemented the hook_install (my_module_install).
Can I use more one implementation of hook_install to create new content type (my_cck_install) in this module?
If (yes), how should I do this?
Else: have I do this in another module? :-)
You can't use more than one implementation of hook_install in the same module; in PHP you can't have 2 function with the same name which rules this out.
You would just need to add your new content type in the same hook_install anyway (have a look at how the standard installation profile does it at /profiles/standard/standard.install). This is how I always add new content types from the install file (using the example of a testimonials module):
function testimonial_install() {
// Make sure a testimonial content type doesn't already exist
if (!in_array('testimonial', node_type_get_names())) {
$type = array(
'type' => 'testimonial',
'name' => st('Testimonial'),
'base' => 'node_content',
'custom' => 1,
'modified' => 1,
'locked' => 0,
'title_label' => 'Customer / Client Name'
);
$type = node_type_set_defaults($type);
node_type_save($type);
node_add_body_field($type);
}
}
The following code will create a content type called "Event" with a machine name of 'event' and a title field -
//CREATE NEW CONTENT TYPE
function orderform_node_info() {
return array(
'event' => array(
'name' => t('Event'),
'base' => 'event',
'description' => t('A event content type'),
'has_title' => TRUE
),
);
}
function event_form($node,$form_state) {
$form['title'] = array(
'#type' => 'textfield',
'#title' => t('event Title'),
'#default_value' => !empty($node->title) ? $node->title : '',
'#required' => TRUE,
'#weight' => -5
);
return $form;
}
//END CONTENT TYPE
you should place it in your .module file... if you want do add additional fields to it, let me know and I'll patch you up with the code... good luck!
/**
* Implements hook_node_info()
*/
function mymodule_node_info() {
return array(
'news' => array(
'name' => t('News'),
'base' => 'news',
'description' => t('You can add News here'),
'has_title' => TRUE,
'title_label' => t('News title')
)
);
}
/**
* Implement hook_form()
*/
function mymodule_form($node, $form_state) {
return node_content_form($node, $form_state);
}
Add the implementation to mymodule.install is as follows:
/**
* Implements hook_install().
*/
function mymodule_install() {
node_types_rebuild();
$types = node_type_get_types();|
node_add_body_field($types['news']);
}
You can get a detailed description with code from here
/*
* Implementation in hook node info in .Module file
*/
function test_node_info() {
return array(
'product' => array(
'name' => t('Product'),
'base' => 'product',

)

'type' => 'text',
'label' => $t('Description'),
'widget' => array(
'type' => 'text_textarea_with_summary'
),
'display' => array(
'example_node_list' => array(
'label' => $t('Description'),

),
);
}
/**

function test_uninstall() {
$ournewtype = 'product';
$sql = 'SELECT nid FROM {node} n WHERE n.type = :type';
$result = db_query($sql, array(':type' => $ournewtype));
$nodeids = array();
foreach ($result as $row) {
$nodeids[] = $row->nid;
}
node_delete_multiple($nodeids);
node_type_delete($ournewtype);
}
That's it.
