Drupal module Features. Some Tips.
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>'. $changed .'</div>'; }
?>
</div>Drupal 6. Disable mail field on the user account page
If you need to make email field disabled, it won't be anough just make it #disabled.
You have to add the same hidden field:
<?php
function [modulename]_form_alter(&$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';
$form['account']['mail']['#disabled'] = TRUE;
}
break;
}
}
?>Drupal. How to use an image field from the profile node instead of user picture (avatar)
I've recently had to make default pictures for user pictures,
but they had to be defferent for different user roles.
I used the module content_profile
and created two profile content types for Student and Teacher roles.
So I decided to change a user picture derectly in my theme.
I change the preprocess function mytheme_preprocess_user_picture from the user module in the template.php file:
<?php
function mytheme_preprocess_user_picture(&$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
How to remove unnecessary links from the group of links under node.
How to change Description textfield for filefield to textarea
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
It is a snippet - how to create custom tokens for specific replacements that can improve other modules relying on Token.
Featured articles changed every 24 hours
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.
Drupal Google maps. I choose the Simplest gmap
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.
Gallerix: photogallery for Drupal - my notes
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)
