I created a module to do all my form altering called "form_mods". It's working for most situations but not for the Taxonomy page.
I'm targeting the form id of "taxonomy_overview_vocabularies". I'm trying to hide the link "edit vocabulary" for roles of "webmaster" and "dj".
My code is unsetting the $form array correctly, but Drupal is still displaying the "edit vocabulary" link.
function form_mods_form_alter($form, $form_state, $form_id) {
if($form_id == 'taxonomy_overview_vocabularies'){
global $user;
$hide=0;
$hideArray = array('webmaster', 'dj');
foreach($user->roles AS $key => $value){
if(in_array($value, $hideArray)){
$hide++;
}
}
if($hide){
foreach($form AS $vocab){
//print_r($vocab);
if(isset($vocab['edit']['#value'])){
unset($vocab['edit']['#value']);
}
}
}
}
}
Very small PHP mistake,
when you want to change array members in a for each statement you have to pass them by reference & foreach($form AS &$vocab) otherwise the $vocab would be just a copy of the array
foreach($form AS &$vocab){
//print_r($vocab);
if(isset($vocab['edit']['#value'])){
unset($vocab['edit']['#value']);
}
}
In addition to Amjad's answer, if you don't like using references, I would suggest another alternative:
foreach ($form as $key => $vocab) {
unset($form[$key]['edit']['#value']);
}
This way you avoid using references, and potential issues they may lead to.
Also note I removed the if statement, which is not useful (PHP can figure it out).
An array_map could also be considered.

I've successfully created a custom view template for my Drupal 7 site but am having issues adding attributes to the content which is outputted. I've searched high and low for the answer to this but to no avail.
I have a view called: views-view-fields--homepage-articles.tpl.php
I am printing content like :
$fields['title']->content
This is fine and expected, and outputs:
Title
But I want to add classes to it - how? I'm thinking I need to write a hook, but I cannot find this documented anywhere. At the moment my solution is a string replace:
<?php print str_replace('<a ', '<a class="brand-blue uppercase nodecoration"', $fields['title']->content); ?>
As you can imagine, this is not a satisfactory or long-term solution.
Many thanks!
You should be able to add the classes to the field using template_preprocess_views_view_fields().
Edit: Couldn't do it the way I thought, but you can overwrite the output of the field like so:
function MY_THEME_preprocess_views_view_fields(&$vars) {
$view = $vars['view'];
if ($view->name == 'node_listing') {
foreach ($vars['fields'] as $id => $field) {
if ($id == 'title') {
$field_output = l($view->result[$view->row_index]->node_title, 'node/'. $view->result[$view->row_index]->nid, array('attributes' => array('class' => 'brand-blue uppercase nodecoration')));
$vars['fields'][$id]->content = $field_output;
}
}
}
}
Have you tried using Semantic Views? https://drupal.org/project/semanticviews - that way you can override the classes within the UI instead of template files, may suit your needs better.
I want a warning message displayed in the comment form when people try to add comments:
"Please write comments in correct
grammatical English, otherwise they
will not published"
How can I do it?
Here is how you can do it by using hook_form_alter in your own module:
function mymodule_form_alter(&$form, &$form_state, $form_id) {
switch ($form_id) {
case "comment_form":
$form['#prefix'] .= "<div><p>Show some text before the comment form.</p></div>";
break;
}
}
You can alter the comment form so that your guidelines are added to it. There are a handful of ways to alter forms in Drupal. You can do it in your theme's template.php file (which I prefer for simple changes) or in a custom module. This article describes both methods, in Drupal 5 and 6, however not for the form you're interested in. However, the method used is the same that leads to the solution below. This is how you can make the change via template.php:
The following PHP code can be added to your theme's template.php file:
function YOURTHEME_theme() {
return array(
'comment_form' => array(
'arguments' => array('form' => NULL),
),
);
}
function YOURTHEME_comment_form($form) {
$output = '';
$output .= '<div class="comment-help">' . t('Please write comments in correct grammatical English, otherwise they will not published.') . '</div>';
$output .= drupal_render($form);
return $output;
}
Replace YOURTHEME with the name of your theme. If you already have a YOURTHEME_theme function you will need to add the 'comment_form' key to the array it is already returning. I doubt you do, but it's worth mentioning just in case.
A note: you should not be editing any of the themes in /themes, but you should have made a new theme or copied and renamed any of those themes into /sites/default/themes or /sites/all/themes.
The above code is based on code from this page.
Once you are inside a hook_form_alter function you can use the Development module (http://drupal.org/project/devel) dpm() function in place of var_dump to help view and isolate which properties to change in the big form arrays. I find this is a must-have when trying to figure out changes to an existing form. It puts all the elements of the form array into clickable rows.
In Drupal 7 go to
admin/structure/types/manage/mycontenttype/comment/fields/comment_body
There you can add your text. It will be shown below the field as usual. If you want the warning displayed above the field, you'd have to go the form_alter way.
I'm looking forward to implement taxonomy terms based css styling; especially for the body tag which i want to add the current terms.
For now, here's what i have so far :
function _phptemplate_variables($hook, $vars = array()) {
global $node;
switch ($hook) {
case 'page': die ('test');
$vars['body_class'] = '';
if (arg(0) == 'taxonomy' && arg(1) == 'term' && is_numeric(arg(2))) {
$vars['body_class'] = 'theme'.arg(2);
}
if (arg(0) == 'node' && is_numeric(arg(1))) {
$node = node_load(arg(1));
if (is_array($node->taxonomy)) {
foreach ($node->taxonomy as $term) {
$vars['body_class'] .= 'theme'.$term->tid;
}
}
}
if (drupal_is_front_page()) {
$vars['body_class'] .= ' front';
}
break;
}
return $vars;
}
I think the code is OK, but it never get called (see my 'die' function); using simple phptemplate engine and minimal drupal6 install.
What obviousity am I missing here ?
/**
* Override or insert PHPTemplate variables into the templates.
*/
function phptemplate_preprocess_page(&$vars) {
//
}
/**
* Override or insert PHPTemplate variables into the templates.
*/
function phptemplate_preprocess_node(&$vars) {
//
}
Well, years ago we wrote this up http://openconcept.ca/blog/jmlane/taxonomy_specific_css
It would need to be updated I expect for Drupal 6 or 7 but the principals still apply.
For Drupal 7 a more elegant solution might be to use the Context module. See the following posting for detailed information and instructions.
Add a body class based on a node's vocabulary term
The Context modules allows for creating arbitrary contexts for specific Drupal pages, e.g. based on taxonomy terms. These contexts can trigger certain reactions, e.g. add a CSS class with the chosen taxonomy term.
For example, in the registration form, there is "Username" and the text field for it which has the input type="text" name="name" ....
I need to know how can I get the title from the input field's name.
I'm expecting a function like:
$title = get_title_for_element('name');
Result:
assert($title == 'Username'); // is true
Is there something like this in Drupal?
Thanks.
You have the form and the form state variables available to your validation function. You should use form_set_error() to set the error.
There is no function that I am aware of which will map from the values array to the form array. But it is not dificult to work it out. Understanding the form data structure is one of the key skills you need when building drupal.
In this case the form in question is generated (in a roundabout way) by user_edit_form, you can see the data structure in there.
$form['account']['name'] is the username field. and the array key for the title is '#title' as it will be in most cases for form elements.
You can do it in two different ways as I see it. Let's create a module called mycustomvalidation.module (remember to create the mycustomvalidation.info file also).
Note: The code below has not been tested, so you might have to do some minor adjustments. This is Drupal 6.x code by the way.
1) Using hook_user()
What you need is a custom module containing your own implementation of hook_user() http://api.drupal.org/api/function/hook_user/6.
<?php
function mycustomvalidation_user($op, &$edit, &$account, $category = NULL) {
if ($op == 'validate') {
// Checking for an empty 'profile_fullname' field here, but you should adjust it to your needs.
if ($edit['profile_fullname'] != '') {
form_set_error('profile_fullname', t("Field 'Fullname' must not be empty."));
}
}
}
?>
2) Using form_alter() and a custom validation function
Personally, I would go for this option because I find it cleaner and more "correct". We're adding a custom validation function to our profile field here.
<?php
function mycustomvalidation_form_alter(&$form, $form_state, $form_id) {
// Check if we are loading 'user_register' or 'user_edit' forms.
if ($form_id == 'user_register' || $form_id == 'user_edit') {
// Add a custom validation function to the element.
$form['User information']['profile_fullname']['#element_validate'] = array('mycustomvalidation_profile_fullname_validate');
}
}
function mycustomvalidation_profile_fullname_validate($field) {
// Checking for an empty 'profile_fullname' field here, but you should adjust it to your needs.
if ($field['#value'] != '') {
form_set_error('profile_fullname', t("Field %title must not be empty.", array('%title' => $field['#title']));
}
}
?>
I want to customize my Drupal back-end forms.
I'm using template.php file.. i.e.
$form['menu']['#collapsed'] = true;
$form['author']['#collapsed'] = true;
$form['buttons']['#weight'] = 100;
But I was wondering from where the section names (menu, author, buttons), come from. (They are not id or classes in html code, so I guess there is an index with all names stored somewhere.
Where can I get the complete list of section names ?
For example, what are the names for revision and publishing sections ? 'revision', 'publish', 'publishing' don't work.
thanks
If I am not mistaken, you want to see structure of some forms. Each form in drupal has an Id. First, you need to know the form_id. You can do this with a custom module and implementation of hook_form_alter:
function mymodule_form_alter(&$form, $form_state, $form_id) {
drupal_set_message($form_id);
}
When you have found the Id, alter the snippet to prints out the form structure:
function mymodule_form_alter(&$form, $form_state, $form_id) {
if ($form_id == 'a_form_id') {
drupal_set_message(print_r('<pre>'. $form .'</pre>', true));
// If you have installed Devel module, following line is much more readable:
// dpm($form);
}
}
Now when you go to the page containing the form, you see it's structure.Each form element is represented as an array, for example, a text field can be like this:
$form['name'] = array(
'#type' => 'textarea',
'#title' => t('Username')
);
Look for Form API in Drupal website for more info.
I don't think there actually is a naming system with forms like that. The names is most likely the same used when defining the form, which could be anything really. Drupal core might be consistent, but if you want to add contrib modules, you can't be sure of anything.
