Adding space to select option in form alter - drupal

I have taxonomy terms hierarchy and I am using them as a filter in a view. It is showing hierarchy in the selectbox, but child terms appearing with hyphen(-). I have tried to drop hyphen in form alter, and I did, but I couldn't replace it blank space.
if ($form_id == 'views_exposed_form') {
$i = 0;
foreach ($form['field_region_tid']["#options"] as $op) {
foreach ($op->option as $key => $arr) {
if ($arr != null) {
$form['field_region_tid']["#options"][$i]->option[$key] = str_replace("-"," ", $arr);
}
}
$i++;
}
}
How can I put blank space at the beginning of the child options. Or should I do some other way?
Thanks!

From the form_id I get that it is a form generated by views. If so, the code inside the if condition never gets called because your module is executed after the views module due to the weight of both modules. To fix that:
Open your database manager (PhpMyAdmin in most cases) and open system table.
Then change the weight for your module to something larger than 10, because it is the default weight for the views module and you need you module to be executed after the views module.
Hope this helps... Muhammad.

if the problem is when your hook is called the answer lies in
hook_module_implements_alter()
but it is not as you say. Your code looks fine,
Have you tried
str_replace("-"," ", $arr);
?

Drupal 7 Views custom view template fields

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.

Get $node variable in html.tpl.php - Drupal 7

I'm trying to allow users to update head titles and meta descriptions for each page. I thought that an easy way to achieve this would be to add a field to the 'Basic page' content type for the page title, then check if that field is not empty in html.tpl.php and if it is not, override $head_title with this user-defined value.
However, it appears that the $node variable is not available in html.tpl.php. Can anyone suggest a way for me to make this data available in this template file, or alternatively, alter $head_title before it is sent to html.tpl.php? Thanks for reading.
Taken in part from this thread that I found: http://drupal.org/node/1041768...
In your template.php, you can do the following:
function yourtheme_preprocess_html(&$variables) {
// If on an individual node page, add the node type to body classes.
if ($node = menu_get_object()) {
$variables['head_title'] = $node-> // find your cck field here
}
}
Bit messy, but would work:
if(arg(0) == 'node' && !empty(arg(1))) {
$node = node_load(arg(1));
}
However, you might prefer http://drupal.org/project/metatags_quick (an interrim module until the full http://drupal.org/project/metatags is finished).

How to hide Edit | View tabs?

Can I hide the
Edit | View
tabs on top of each node ?
I've searched for this option in theme settings (both global and standard theme but I couldn't find it).
I still want to be able my customer to edit / administer content, so I cannot just remove the permission for it.
thanks
here is a very easy solution for you. (Drupal 7)
Open your page.tpl.php in your current template and search for the $tabs variable.
Remove the render code if you want to hide it completely.
If you want to display it only to administrators use this code
<?php if ($tabs and $is_admin): ?>
<div class="tabs">
<?php print render($tabs); ?>
</div>
The above code checks if the user is administrator. If it is it will render the tabs. If not it wont render them.
This really is a presentational thing, not a functionality thing, so it should be done at the theme level.
The problem with overriding theme_menu_local_tasks() is that you override/take a hatchet to the entire local task display, when you really just want to get in there with a scalpel to remove two specific local tasks. So, you need to get a little more specific.
theme_menu_local_tasks() gets the current page's local tasks and passes them to menu_local_tasks(). Here, two theme functions are used:
theme_menu_item_link(), which gets the link markup for the task
theme_menu_local_task(), which gets the <li> element for the task.
So, you can get rid of the View and Edit local tasks in a really robust way by overriding theme_menu_item_link() and theme_menu_local_task() to include your check for them:
function mytheme_menu_item_link($link) {
// Local tasks for view and edit nodes shouldn't be displayed.
if ($link['type'] & MENU_LOCAL_TASK && ($link['path'] === 'node/%/edit' || $link['path'] === 'node/%/view')) {
return '';
}
else {
if (empty($link['localized_options'])) {
$link['localized_options'] = array();
}
return l($link['title'], $link['href'], $link['localized_options']);
}
}
function mytheme_menu_local_task($link, $active = FALSE) {
// Don't return a <li> element if $link is empty
if ($link === '') {
return '';
}
else {
return '<li '. ($active ? 'class="active" ' : '') .'>'. $link ."</li>\n";
}
}
This way, you're relying on the menu router path, not modifying the menu router item, and achieving the result you want with minimal changes to core functionality or theming.
On the module side, you could do something that decouples the Edit's menu entry from the local tasks for the node:
function custom_menu_alter(&$items) {
$items['node/%node/edit']['type'] = MENU_CALLBACK;
}
The edit path is still there, but now it is not associated with the View tab. This includes the edit page itself--no View tab there.
there is a module for that: tab tamer allows to hide or disable tabs and rename them as well.
I use the following in template.php by theme (which is perhaps a little hacky, I feel I should be considering unsetting $tabs instead):
function THEME_NAME_menu_local_tasks() {
return '';
}
Or you could ommit:
if ($tabs) echo $tabs;
from your page.tpl.php...
View and Edit are functional features. They have a reason for being there.
The best way to "remove" them, is to "remove" that functionality alltogether. After all: why remove the interface of a piece of functionality, but not the functionality itself?
Besides, simply not printing the tabs, does not remove the url endpoints. In other words: if you don't print the edit tab, people can still access the edit page.
Again: best is to remove that functionality: The fact that you don't want the edit tab, sounds as if you don't want the edit functionality for certain users.
If so, then just remove that permission for that role. That is all. The tabs will be gone.
If, however, you simply wish to display these tabs differently, Drupal is your friends. As you may have noticed, they are called local tasks and not tabs. That is because the theme decides how to render them: The theme is the thing that decides to show them as tabs.
Simply override the theme_menu_local_tasks() to create your own HTML for the "local-tasks". And in your page-tpl, simply move the $tabs variable around to a place, where you want them.
But again: Don't try to change the behavior of the app, by removing interface-elements. That is not the right thing to do: you should change the behavior, in order to change the behavior :)
For all the people stumbling upon this question while looking for a D7 solution: As stated on https://drupal.stackexchange.com/a/77964/15055 it's hook_menu_local_tasks_alter()
/**
* Implements hook_menu_local_tasks_alter() to unset unwanted tabs
*/
function MYMODULE_menu_local_tasks_alter(&$data) {
foreach ($data['tabs'][0]['output'] as $key => $value) {
if ($value['#link']['path'] == 'node/%/view') {
unset($data['tabs'][0]['output'][$key]);
}
}
}
This is not the answer to the question of what the author asked. But somehow it might be useful for others user who facing the similar problem with me. Please let me know if this is not suitable to put in here.
I get the answer from #grayside and modified a bit to hide the view | edit tab from node based on the content type I want.
function MYMODULE_menu_alter(&$items) {
$items['node/%node/view']['access callback'] = 'MYMODULE_disable_node_view';
$items['node/%node/view']['access arguments'] = array(1);
}
function MYMODULE_disable_node_view($node){
if($node->type == 'product'){
return false;
}
}
product is the machine name of my content type, I don't want anywant to access it including root user.
The simplest solution to hide the tabs is to add this class in your theme css
.tabs{ display:none;}
Thanks for the last answer. But be aware of this detail: if you try it as-is it cannot work: literals should be just rounded with " or ', not both of them altogether. So it should be:
/**
* Implements hook_menu_local_tasks_alter() to unset unwanted tabs
*/
function MYMODULE_menu_local_tasks_alter(&$data) {
foreach ($data['tabs'][0]['output'] as $key => $value) {
if ($value['#link']['path'] == "node/%/view") {
unset($data['tabs'][0]['output'][$key]);
}
}
}
Once taken care of it, it works :)
D8 solution: If you want to hide all "local" tabs on certain pages, remember that "Tabs" is listed in the block library: find it in the "Content" region and exclude by content type, page URL or user role.

Hide link to a Views' view if the view is empty

I have a Drupal 6.14 site with Views module. I have a view and on the primary links I put a link to the view.
There is a way to hide the link in the primary menu only if the view is empty?
You could probably do this either via a theme or module implementation of preprocess_page (THEMENAME_preprocess_page(&$vars) or MODULENAME_preprocess_page(&$vars)), but mac above is correct in that views are not known to be empty or not until they are run, so there will be a performance hit.
Within the function, you should have access to the structured primary links array, so you can run the view:
$view = views_get_view('view_name');
// Swap out 'default' for a different display as needed. Also, $args are arguments, and can be left out if not applicable.
$output = $view->preview('default', $args);
if (empty($view->result)) {
// The view has no results, alter the primary links here to remove the link in question.
}
I am ready to be contradicted any moment as I never implemented anything like that, however I am under the impression that since views are essentially queries against the DB, you can't actually know if a view is empty until you actually invoke it.
Consider that - given you are speaking about primary links (shown on nearly every page of your site) this might be a serious performance hit, depending on the complexity of the view and on its "cacheability".
You should also consider whether the content of that view can be changed by other users browsing the site at the same time that "our" user: should the view become populated after "our" user has loaded the page, "our" user won't ever know.
As on how to achieve what you want, please see the accepted answer.
HTH!
I override views_embed_view() to only provide output if there is content, and then call my override from the theme layer:
function mymodule_embed_view($name, $display_id = 'default') {
// handle any add'l args (this hook supports optional params)
$args = func_get_args();
array_shift($args);
if (count($args)) {
array_shift($args);
}
$view = views_get_view($name);
$output = $view->preview($display,$args);
if ($view->result) {
return $output;
}
}
Then in the template file:
<?php
$view = mymodule_embed_view('view_name');
if (strlen($view) > 0) {
print $view;
}
?>

Why isn't $vars['node'] available in preprocess_page for some content types?

I am currently using drupal 6 for a site I'm working on. I have a MYTHEME_preprocess_page() function that adds a few variables to the page.tpl.php template from the taxonomy and from a cck field. It was working correctly for a bit, and then the $vars['node'] is empty, but only for 2 content types. The 'node' variable is available to the preprocess_page function in other content types.
I thought it was a problem with using the following code, but when I remove all of this, the 'node' variable is still empty.
function mytheme_preprocess_node(&$vars, $hook) {
$function = 'mytheme_preprocess_node'.'_'. $vars['node']->type;
if (function_exists($function)) {
$function(&$vars);
}
}
Does anyone know of any gotchas or bugs that might be removing the 'node' variable? I can't seem to figure out where I'm going wrong. I'm at a loss.
Here is my complete mytheme_preprocess_page() function.
function mytheme_preprocess_page(&$vars, $hook) {
if ($hook == 'node' || $hook == 'page') {
if (is_object($vars['node'])) {
// grab the header image if it exists to make it avaialble to the content header
$vars['header_image'] = _mytheme_get_header_image($vars);
// get the taxonomy term to put in the content header
if (count($vars['node']->taxonomy) > 0) {
$vars['tax_term'] = "<div class=\"terms\">" . _mytheme_get_first_taxonomy_term($vars['node']->taxonomy) . "</div>";
}
// add the teacher's credentials to the content header
if ($vars['node']->field_credentials[0]['view'] != '') {
$vars['teacher_credentials'] = '<span class="teacher-creds">' . $vars['node']->field_credentials[0]['view'] . '</span>';
}
}
}
}
After going through and disabling modules one-by-one, I determined that the problem is related to the module, node_breadcrumb. A similar issue was filed here: http://drupal.org/node/616100#comment-2199374
In the 3rd comment, you'll see a link to another issue with a resolution
For others that run into this, I had the same issue as a result of using the jQuery UI module. Disabling and re-enabling fixed it, and I could not track down the specific issue, but it appeared to be related to $static variables in some path check functions.
To others that stumble their way into here, I suggest you pull some of the more obvious modules right out of the module folder on your dev setup, see if things change, and then put them back in there until you figure it out.
Another option is to search for instances of _preprocess_page(, $variables['node'] and $vars['node'] to see if some contributed code is unwittingly unsetting a node when it shouldn't be.
