Drupal 6. Показываем тип ноды для админов.

Julia — Wed, 27 Apr 2011 20:26:52 +0000

<?php
/**
 * Implementation of hook_perm
 */
function [your module]_perm() {
  return array(
    'view node type'
  );
}

function [your module]_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL){ 
  switch ($op) {
    case 'view':
      if (user_access('view node type')){  
        $node->content['node_type']['#value'] = '<div class="node-type">'. t('Material type :: '). node_get_types('name', $node) .'</div>';
        $node->content['node_type']['#weight'] = -10;    
      }
  }
}
?>

Чтобы это работало, в теме в файлах типа node.tpl.php должна выводиться переменная $content.
(Если же вам не нужны какие-то поля в этой переменной, удалите их оттуда с помощью настроек - галочка в настройках полей Display fields )

How to show list of grouped categories

Julia — Mon, 03 Jan 2011 11:55:38 +0000

This is a snippet about creating grouped categories list with views - how it is popular in russian forums - see the picture.

1. First of all - this is term type view (displaying items of type Term). You have to choose this option on the first step of creating view.

2. We need two columns, that's why I use 2 displays: page display and attachment to the page.

2. For grouping terms by the parent term, I use relationship Taxonomy: Parent term.

- that is all main key points, everything I can see on the second picture, attached to the post.

Drupal module Features. Some Tips.

Julia — Thu, 29 Jul 2010 13:04:43 +0000

Module features is necessary for site builders in order to maintain big projects.

Some tips about this great module:

Doesn't want to be reverted

It happens sometimes that overridden feature pack doesn't want to be reverted,
for example after updating it in another system.

The solution is simple, if this feature pack has views objects.
You just have to flush views cache and try again.

Show views that are overridden

If you have a lot of feature packs with many views in them
and one of views was changed - in the overridden section
you won't understand the name of view that was changed.

To see it - add template file to your theme:
features-admin-components.tpl.php

<div class='clear-block features-components'>
  <div class='column'>
    <div class='info'>
      <h3><?php print $name ?></h3>
      <div class='description'><?php print $description ?></div>
      <?php print $dependencies ?>
    </div>
  </div>
  <div class='column'>
    <div class='components'>
      <?php print $components ?>
      <div class='buttons clear-block'><?php print $buttons ?></div>
    </div>
  </div>
  <?php print $form ?>
  
<?php    
$component = 'views';
$normal = features_get_normal($name, $component);
$default = features_get_default($name, $component);
foreach ($normal as $k => $view){
   $compare = array('normal' => features_var_export($normal[$k]), 'default' => features_var_export($default[$k]));
        if (_features_linetrim($compare['normal']) !== _features_linetrim($compare['default'])) {
          $changed .= l($k, 'admin/build/views/edit/'. $k) . '<br/>';
        }
}
if ($changed) {print '<div><h4>Changed views:</h4>'. $changed .'</div>'; }
?>
</div>

Drupal 6. Disable mail field on the user account page

Julia — Tue, 08 Jun 2010 09:18:32 +0000

If you need to make email field disabled, it won't be anough just make it #disabled.
You have to add the same hidden field:

<?php
function [modulename]_form_alter(&$form, $form_state, $form_id) {
    global $user;

  switch ($form_id) {
      case 'user_profile_form':
          if ($user->uid != 1){
          // fields must have a hidden field w/ proper value as disabled fields are not submitted.
        $form['account']['readonly']['mail'] = $form['account']['mail'];
        $form['account']['readonly']['mail']['#type'] = 'hidden';
            $form['account']['mail']['#disabled'] = TRUE;
          }
          break;
  }
}
?>

Drupal Theme by pieces. Menu links (Primary and Secondary)

Julia — Tue, 13 Apr 2010 12:53:12 +0000

В этом сниппете из цикла Theme by pieces о главном меню.

в page.tpl.php:

<?php if ($primary_menu): print $primary_menu; endif; ?>
<?php if ($secondary_menu): print $secondary_menu; endif; ?>

В template.php в функции
mytheme_preprocess_page(&$vars, $hook):

Стандартный вариант:

<?php
if (!empty($vars['primary_links'])) {
    $vars['primary_menu'] = theme('links_primary', $vars['primary_links'], array('class' => 'bookmarks'));
  }
?>

Дополнительный шаблон

Для сложной верстки, когда не хватает стандартных тегов ul/li,
например, когда меню имеет круглые края.
В этом случае удобнее включить дополнительный шаблон.

<?php
?>

Plain links

For example for Secondary links:

_preprocess_page(&$vars, $hook)

<?php
if (!empty($vars['secondary_links'])) {
    $vars['secondary_menu'] = theme('links_secondary', $vars['secondary_links'], array('class' => 'static-menu'));
  }
?>

<?php
/**.
* Implementation of hook_theme.
*
* Register custom theme functions.
*/
function renlife_theme() {
  return array(        
     'links_secondary' => array(
      'arguments' => array(
        'links' => NULL,
        'attributes' => array('class' => 'links'),
        'settings' => array(
          'delimiter' => '',
          'leftcab' => NULL,
          'rightcab' => NULL,
        )
      ),
      'template' => 'links-plain',
     )    
  );
}
?>

Для plain меню, когда разметка меню не содержит ul/li,
но содержит разделители между пунктами тип "|",
используем дополнительный шаблон
plain

<?php
/**
* This snippet changes links layout.
*/
$output = '';
if (count($links) > 0) {
  $output .= '<div'. drupal_attributes($attributes) .'>';
  
  // Display the right cap of the 'button bar'.
  if (!empty($settings['leftcab'])) {
    $output .= $settings['leftcab'];
  }
  // Build the list of themed links.
  $link_list = array();
  foreach ($links as $link) {
    if (isset($link['href'])) {
      // Pass in $link as $options, they share the same keys.
      $link_list[] = l($link['title'], $link['href'], $link);
    }
    else if (!empty($link['title'])) {
      // Some links are actually not links, but we wrap these in <span> for adding title and class attributes
      if (empty($link['html'])) {
        $link['title'] = check_plain($link['title']);
      }
      $span_attributes = '';
      if (isset($link['attributes'])) {
        $span_attributes = drupal_attributes($link['attributes']);
      }
      $link_list[] = '<span'. $span_attributes .'>'. $link['title'] .'</span>';
    }
  }
  // Add delimiter between the links.
  if (!empty($settings['delimiter'])) {
    $output .= implode($settings['delimiter'], $link_list);
  }
  else {
    $output .= implode('', $link_list);
  }
  // Display the right cap of the 'button bar'.
  if (!empty($settings['rightcab'])) {
    $output .= $settings['rightcab'];
  }
  
  $output .= '</div>';
}
print $output;
?>

Drupal. How to use an image field from the profile node instead of user picture (avatar)

Julia — Tue, 19 Jan 2010 12:23:34 +0000

I've recently had to make default pictures for user pictures,
but they had to be defferent for different user roles.

I used the module content_profile
and created two profile content types for Student and Teacher roles.
So I decided to change a user picture derectly in my theme.

I change the preprocess function mytheme_preprocess_user_picture from the user module in the template.php file:

<?php
function mytheme_preprocess_user_picture(&$variables) {
$variables['picture'] = '';
  
    $account = $variables['account'];
    
    $user = user_load(array('uid' => $account->uid));    
    $roles = $user->roles;
    $profile = '';    
    if (is_array($roles)) {      
      if (array_search('student', $roles)) {
          $profile = 'studentprofile';
      } else if (array_search('sensei', $roles)) {
          $profile = 'profile';
      }
    }
    
    if (!empty($profile)) {
      $node_profile = content_profile_load($profile, $account->uid);
      $field_photo = content_fields('field_photo', $profile);
      
      $picture = content_view_field($field_photo, $node_profile);
    } else {
    
        // from default preprocess_user_picture:
        if (!empty($account->picture) && file_exists($account->picture)) {
          $picture = file_create_url($account->picture);
        }
        else if (variable_get('user_picture_default', '')) {
          $picture = variable_get('user_picture_default', '');
        }
    
        if (isset($picture)) {
          $alt = t("@user's picture", array('@user' => $account->name ? $account->name : variable_get('anonymous', t('Anonymous'))));
          $variables['picture'] = theme('image', $picture, $alt, $alt, '', FALSE);
          if (!empty($account->uid) && user_access('access user profiles')) {
            $attributes = array('attributes' => array('title' => t('View user profile.')), 'html' => TRUE);
            $variables['picture'] = l($variables['picture'], "user/$account->uid", $attributes);
          }
        }
        // 
        
    }
    $variables['picture'] = $picture;
}
?>

Drupal 6. Alter links

Julia — Sat, 16 Jan 2010 12:03:07 +0000

How to remove unnecessary links from the group of links under node.

There are two methods for altering links, one at theme layer and the other hrough a custom module.

Use hook_link_alter() in a module

<?php
function mymodule_link_alter(&$links, $node) {
  foreach ($links as $module => $link) {
    if (strstr($module, 'blog')) {
      unset($links[$module]);
    }
  }
}
?>

At theme layer

In the template.php file:
change or create the new function phptemplate_preprocess_node(&$vars)

<?php
function phptemplate_preprocess_node(&$vars) {   
// unset from links forward link
   foreach ($vars['node']->links as $module => $link) {
        if ($module == 'forward_links') {
          unset($vars['node']->links[$module]);
        }
      }
   $vars['links'] = theme('links', $vars['node']->links, array('class' => 'links inline'));
}
?>

In this example I removed all links conneted with 'forward' module

How to change Description textfield for filefield to textarea

Julia — Fri, 15 Jan 2010 19:02:17 +0000

This is a little snippet for Drupal6 for changing a textfield to a textarea
in the Description field of the CCK file field (filefield module).

By default, you can enable Description field, but that will be a textfield input with 128 charecters length,
but already two customes have asked me to make this field longer, because this field is shown
under images in the lightbox box.

<?php
variable_set('filefield_description_length', 300);
variable_set('filefield_description_type', 'textarea');
?>

Although the author of this module use variables,
he doesn't give the settings form for them.

How to add a custom token

Julia — Wed, 06 Jan 2010 14:21:30 +0000

It is a snippet - how to create custom tokens for specific replacements that can improve other modules relying on Token.

Custom implementation

Firstly, how can you create own tokens in a module yourself.
This is a small snippet about creating own token.

For example I use content_profile module I wish to have the title of profile node in my tokens.

Before that, don't forget to enable the Token module

<?php
/**
 * Implementation of hook_token_values().
 */
function [mymodulename]_token_values($type, $object = NULL, $options = array()) {
  $values = array();
  switch ($type) {
    case 'node':
      if (isset($object)) {
        $account = user_load(array('uid' => $object->uid));
      }
      else {
        global $user;
        $account = user_load(array('uid' => $user->uid));
      }
      
      
      $node_profile = content_profile_load('profile', $account->uid);
      $values['profile'] = ($node_profile->title) ? $node_profile->title : '';      
      
      
      break;
  }
  return $values;
}
/**
 * Implementation of hook_token_list().
 */
function [mymodulename]_token_list($type = 'all') {
  if ($type == 'node' || $type == 'all') {
    $tokens['node']['profile']       = t("Profile title of authors content profile");
    
    return $tokens;
  }
}
?>

Module Custom Tokens

Also you can try to use the Custom Tokens module

From the desciption of this module:
"Advanced module, PHP code evaluation and execution
This module is designed for developers with, at least, a little PHP knowledge. Custom tokens will evaluate and execute PHP snippets in order to provide the replacements for the tokens you define."

Featured articles changed every 24 hours

Julia — Sun, 21 Jun 2009 17:18:37 +0000

So here’s the scenario. For one site it’s been decided that every 24 hours they want the frontpage to change featured article.

Is there a way to do two things.

1) Change featured article (homepage only) every 24 hours.
2) Have the ability to change the article to anything they want.

Problems

There are some problems with it.

What exactly the rule of changing nodes,
what is the sequence of nodes that have to be changed automatically?

Unfortunately, we can’t just remove node from nodequeue (the last or the fisrt one) automatically once a day because there are no Actions for it (actions module)
only Action for removing and additing particular node

And nodequeue doesn’t support Rules module – there are no special conditions for rules that could be useful for this task.

That’s why we can’t change node queue by cron
if we don’t know what exactly node has to be added.

At least, I didn’t find any possibilities to do that,
maybe I’m wrong.

We need to know what node have to be shown today
with that parameters.
For example, node with the value of a field is equal to current day
or node with taxonomy term = current day

My solution

I found only one solution, I tried tons of different combinations
and stopped on this one, which seems to me quite logical and convenient:

For the frontpage I created Frontpage queue by nodequeue module
(it is shown on frontpage by view
with maximum nodes in queue, for example = 3)

So after additing a new node to the queue first node will be removed from it.

And I added Triggered rule and Rule set.

Triggered rule – for firing the rule set after additing new content

Rule set – for adding node,
which was just created and which is promoted to front page, to the queue, but not only, this rule set has a schedule in order to be firing once a day while this node is promoted to front page
so we have a circle for changing nodes if there isn’t any new node for frontpage

and in any time we can add any new node to the queue to show it on frontpage.

Modules that I used:

- Nodequeue
- Rules

For random image

There is much easier solution:

Just use views with random sort criteria -
special module Views random seed (Adds a random order handler with seed so random order listings with paging works).

Drupal Google maps. I choose the Simplest gmap

Julia — Sun, 21 Jun 2009 15:04:06 +0000

The common task is:
- add location to a node by pointing it on the google map, highly desirable with cck field
- create maps with groups of node on one map with views.

I worked with GMap and location,
I saw at the newer module Google Maps Tools as well,

but when I've found Simplest gmap module I understood that is really what I need.

The main advantages of this module in my opinion:
- really very simple and small
- that is a CCK field
- perfect map widget
(when you drop a marker, it doesn't zoom in as other modules)

There are no any requirements for this module.

There is a one weakness of this field - there are no way to add location
by typing city, country and so on, only by dropping marker.

Views

And what about views integration?
Maintainer says that he is going to do that,
but even now we have such possibility!

Download and enable modules:
- Computed field
- Mapstraction - for views map style
Of course - Simplest gmap and Views as well.
Then create content type with three fields:
- field of type Simplest gmap
- Longitude field of computed type
- Latitude field of computed type
Configure computed fields:
Write in the Computed code textarea of your Longitude and Latitude fields:

$node_field[0]['value'] = $node->field_geolocation[0]['longitude'];

$node_field[0]['value'] = $node->field_geolocation[0]['latitude '];

respectively,
where field_geolocation - name of your simplest gmap field
Add new view,
add longitude and latitude fields,
for style choose - Mapstraction

And now you have a big map with nodes on it :)

Gallerix: photogallery for Drupal - my notes

Julia — Sun, 21 Jun 2009 12:34:51 +0000

Where are a lot of modules for creating photo galleries with Drupal,
including third-party integration modules - like Gallery2.

Gallerix - that is rather small gallery for photo albums.

However I don't like this module very much,
fortunately, maintainers are going to rewrite it soon.

In my opinion, more flexible way to create photo gallery is just using CCK fields with views:

filefield + imagefield + imagecache + views + lightbox2 (или thickbox)

But recently I needed to customize Gallerix.

Additing additional preset for thumbnails

That is possible to add new sizes for you gallery thumbnails on the Gallerix general settings page (at /admin/gallerix/general)

But it dosn't work. To fix it we have to modify two line in moules/gallerix/managment.inc file:
line 201:

<pre>
$entry['name'] = array(
      '#type' => 'textfield',
      '#size' => 20,
      '#default_value' => $name, // julia changed
      //'#disabled' => $name == 'thumbnail' || $name == 'frame',
);
</pre>

How to add lightbox2

On the main page of Gallerix album there are several little thumbnails and a big photo,
that is ajax reloaded, but the size of this photo is restricted by setting.

And what if you want to see bigger photo and using thickbox, or any other plugin like that.

Let's add these possibility to our gallery.

Firstly, upload and enable LightBox2 module.

Secondly, add javascript file to your theme.
Add this line to your .info file:

scripts[] = 'js/my.js'

Create js folder in your theme with my.js file:

$(document).ready(function(){
   $('.gallerix-thumbnail-link').click(function(){
	href = $(this).find('img').attr('src');
	newhref = href.replace(/thumbnail/, 'original');	
	$('#gallerix-display a').attr({href: newhref});
  });
});

That is all!
Now you can click on the big photo in a Galleix album and you'll see a big Lightbox preview.
