this module does a good job at creating a tagcloud block - all good here. now id also like to have a page that lists all tags with next to each tag the number of posts that were tagged with this term. all terms are listed ok on http://example.com/?q=tagadelic/list/3 but i dont think tagadelic can add the number of posts per tag?
also, it seems tagadelic can just output one single block "tags in tags". whatever changes i make in the tagadelic configuration is applied to the tagadelic/list/3 url AND to the tagcloud block in the sidebar (the order of tags and number of tag levels)
does what i need require some custom module or are there others around that can achieve this? ive been playing around with Views 2 but cant quite get what I need
Use views and views_cloud for a much more flexible solution.
Edit: If you are having trouble with the views module, there is some very good in-browser instructions that come with it, but they require the advanced_help module.
For historical information:
Tagadelic can add the number of posts per tag, just fine. Assuming your theme is called "red":
/**
* theme function that renders the HTML for the tags
* #ingroup themable
*/
function red_tagadelic_weighted($terms) {
$output = '';
foreach ($terms as $term) {
$output .= l($term->name, taxonomy_term_path($term), array('attributes' => array('class' => "tagadelic level$term->weight", 'rel' => 'tag'))) .' ('. $term->count .') ';
}
return $output;
}

Woocommerce have a div with a class "woocommmerce" I want to add another class or remove the class. Which file is that?
<div class="woocommerce"></div>
Although there isn't any supported method provided by WooCommerce for achieving that, you could "hack" on the function which builds the wrapper directly.
The problem
<div class="woocommerce"></div>
"The master wrapper". Almost all things WooCommerce lives within it.
WooCommerce plugin kind of "protects" its main wrapper as it depends on it for doing all kinds of stuff (styling, js functionality) etc. For that reason, the plugin hasn't a filter available so one could hook to and override it.
By the way, it is not recommend to remove it, one would rather add additional css classes to it, which is possible.
There's even a Github issue which seems to state that WooCommerce "Won't fix" it (at least for now).
Use cases
Amongst all possible use cases that might be out there, mine was to apply additional css classes to the wrapper <div class="woocommerce"></div> to fit my theme's CSS framework, (Bootstrap 4) specifically.
I simply wanted it to become <div class="woocommerce container-fluid container-application"></div>
BUT
How to safely change it?
Inspecting it further
Looking at WooCommerce's class-wc-shortcodes.php under the includes/ directory, let's go ahead and dissect it. If you jump to this line you can have a glimpse at the shortcode_wrapper() function, which builds that "annoying" wrapper. Jump here to see an array of woocommerce shortcode slugs, which will have their contents wrapped within the <div class="woocommerce"></div>.
Or according to my own use case, on this specific line, My Account page shortcode is returned within the shortcode_wrapper() function, which again results in all the My Account pages' contents living within the <div class="woocommerce"></div>.
That is also true for other shortcodes used by WooCommerce, so go ahead to the solution part and you might be able to change the wrapper while on other WooCommerce pages other than the My Account.
The Solution (!)
"shut that whole thing down"
We're going to hack on the function which builds the <div class="woocommerce"></div> directly.
We have to create a new shortcode by calling the WC_Shortcodes() class. It will kind of "redirect" all the contents from a specific WooCommerce shortcode to our newly created one.
Now, the following function specifically targets the My Account pages, but it could be easily adapted to conditionally target other pages containing the WooCommerce shortcodes.
So, the default WooCommerce pages as most of you might be aware of, are nothing more than ordinary WordPress pages you can manage under the Admin dashboard. However, those pages do also display the contents of the default WooCommerce shortcodes such as the [woocommerce_my_account], which is the one we'll replace later on.
Place the function bellow on your functions.php, save & upload it.
/**
* WooCommerce My Account
* Returns custom html / css class for WooCommerce default wrapper on My Account pages
* #see https://github.com/woocommerce/woocommerce/blob/857c5cbc5edc0451cf965b19788e3993804d4131/includes/class-wc-shortcodes.php#L59
*
**/
if ( class_exists( 'woocommerce' ) ) {
function wp_wc_my_account_shortcode_handler( $atts ) {
$whichClass = new WC_Shortcodes();
$wrapper = array(
'class' => 'woocommerce container-fluid container-application',
'before' => null,
'after' => null
);
return $whichClass->shortcode_wrapper( array( 'WC_Shortcode_My_Account', 'output' ), $atts , $wrapper );
}
add_shortcode( 'new_woocommerce_my_account', 'wp_wc_my_account_shortcode_handler' );
}
------------------// ------------------
Now, let's head to the My Account Page on the browser and inspect the html, you'll notice nothing has changed. That's because we now have to go to Admin >> pages >> My Account, and then replace the default WooCommerce [woocommerce_my_account] shortcode with the [new_woocommerce_my_account].
Update/Save the My Account page under the Admin Dashboard and now all the My Account pages contents will be wrapped within our new <div class="woocommerce container-fluid container-application"></div>.
Bonus
Constructing custom html for the wrapper
In case you wanted a custom html tag for the wrapper, simply passing the tag along with your css class/classes will do the job. Change the following part of the function above to:
$wrapper = array(
'class' => '',
'before' => '<section class="woocommerce container-fluid container-application>',
'after' => '</section>'
);
And now instead of a <div></div>, our wrapper will be a <section></section>.
Simply follow (enhance) the logic and you'll be able to replace the wrapper on almost all WooCommerce pages such as products, product, product categories, cart, checkout, my account and so on.
there is no ready-made filter or anything like that, that lets you do it, but you could filter the_content, to get it done.
function so33675604_add_class_to_checkout( $content ) {
//condition to check for the proper page
if ( is_checkout() ) :
//disable error reporting for falsy formatted html code
libxml_use_internal_errors(true);
//parse the $content html (treat content as UTF-8, don't add any doctype or other html wrappers)
$html = new DOMDocument();
$html->loadHTML( mb_convert_encoding($content, 'HTML-ENTITIES', 'UTF-8'), LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD );
//search for the very first div
$container = $html->getElementsByTagName('div')->item(0);
//add classes (remember to put woocommerce, since thats been used by some js functions)
$container->setAttribute('class', 'woocommerce oink');
//return the result
return $html->saveHTML();
endif;
return $content;
}
//add the filter (priority must be high, so it runs later, after the shortcodes have been processed)
add_filter( 'the_content', 'so33675604_add_class_to_checkout', 100 );
please be aware, that this function uses conditionals and these might not work in wp-ajax calls / you would have find another way to check, if checkout (or else), probably via global wp_query.
i would like to change the comments per page for only a single node. Let's say that the defaul number of comments per page for the content type "article" is 50 and i want change this to 10 only for the article with nid=171.
$node = menu_get_object('node',1); if($node && $node->nid = 171) {......}
Any hint? Thanks.
If you want to control the number of comments on individual pages, I would suggest installing Views module which allow for easy creation of any lists of things, including comments. With Views, you can create a block with comments for any node and use that instead of regular comments block.
Also, you can have several different blocks with different number of comments, and attach whatever block you want to whatever node. Using Context module would help too, it allows to assign blocks and other elements to pages with much more sophisticated controls than Drupal core block management.
Check out can this be helpful to you:
https://drupal.stackexchange.com/questions/7450/comment-per-page-settings
Since it's a form you have to alter it and change comments number from code.
i found a solution even if a bit rude. To disable the node's default comments i used a preprocess function in template.php file of my subtheme and disbled the $content['comments'] variable used in the comment-wrapper.tpl.php template:
function MYSUBTHEMENAME_preprocess_comment_wrapper(&$vars){
$node = menu_get_object();
if($node):
if($node->type === 'forum' && $node->nid == 171):
unset($vars['content']['comments']);
endif;
endif;
}
Note that i did it for comment wrapper variables/template and not for the node vfariables/template in order to unset the comments but to keep the comment form.
Then i created a view block of comments with a filter for the nid of the comment's node.
This works well for my purposes but if you find a more elegant way let me know. :)
I spent a time looking comment.module and found this in comment_form_node_type_form_alter
$form['comment']['comment_default_per_page'] = array(
'#type' => 'select',
'#title' => t('Comments per page'),
'#default_value' => variable_get('comment_default_per_page_' . $form['#node_type']->type, 50),
'#options' => _comment_per_page(),
);
So I put that in my template.php
function THEMENAME_preprocess_page(&$variables){
if (isset($variables['node']->type)) {
if ($variables['node']->type == 'forum') {
variable_set('comment_default_per_page_' . 'forum', 4);
}
}
}
It worked for me, I hope it helps.
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 = $field_output;
}
}
}
}
Have you tried using Semantic Views? https://drupal.org/project/semanticviews - that way you can override the classes within the UI instead of template files, may suit your needs better.
I am learning Drupal as I go and I am wondering if I can change a link coming from out of a tag cloud.
The link coming from the tag cloud goes to ...category/articles/locations/kittys
I would like it to go to the node tag at ...content/kittys
Any thoughts?
The assummed module you used for this, tagadelic, uses default taxonomy-paths for that.
So the answer is "yes" it can be changed. e.g. Forums (which are terms/tags in a taxonomy too) in a tagcloud will link to the forum home, not to the forum overview. This works because tagadelic uses taxonomy_term_path().
However, your question is a bit unclear about what (and why) you want to achieve this. What is "content/kitties"? Your question makes me believe you want to link to a node? Why? Tag-clouds represent tags, where the tag links to the list of posts within that tag.
That said, the easy way to change outgoing links is in the theme_function: to override the theme function.
/**
* theme function that renders the HTML for the tags
* #ingroup themable
*/
function my_custom_chees_puff_theme_tagadelic_weighted($terms) {
$output = '';
foreach ($terms as $term) {
$output .= l($term->name, "/link/to/anywere", array(
'attributes' => array(
'class' => "tagadelic level$term->weight",
'rel' => 'tag',
'title' => $term->description,
)
)
) ." \n";
}
return $output;
}
The other option is to override the general "where should a tag-link-link-to" Drupalwide. As forementioned forum.module does, trough hook_term_path():
function my_cheesy_puffs_kitten_module_term_path($term) {
return 'links/to/kittens/' . $term->tid;
}
Success! Bèr Kessels - Author and maintainer of Tagadelic :)
I want a warning message displayed in the comment form when people try to add comments:
"Please write comments in correct
grammatical English, otherwise they
will not published"
How can I do it?
Here is how you can do it by using hook_form_alter in your own module:
function mymodule_form_alter(&$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.
