I need to add a condition to a button hard-coded into the template file in a Drupal 7 theme. I would like the 'compare' button only to appear on the node pages of products that have certain taxonomy terms attached to them. I guess, it could be done with a simple IF, but I'm not a developer and only know the very basics of PHP syntax, so I would be really grateful, if someone could describe in detail how to implement a solution, perhaps even provide a snippet of code that I can customize and paste in the right place!
<div class="actions">
<?php print flag_create_link('wishlist', $node->nid); ?>
<?php print flag_create_link('compare', $node->nid); ?>
</div><!-- .actions -->
</div>
This is the section in the code of the node--product.tpl.php file that puts out the action buttons. I would like the second one, the compare button to only appear for nodes that have certain taxonomy terms.
Thank you in advance!

You can use the following code.
<?php
$display_compare = FALSE; // don't display by default
$tids = array(1, 2, 3); // array of certain taxonomy terms' tids
foreach ($node->TERM_FIELD_NAME[LANGUAGE_NONE] as $delta => $term) {
if (in_array($term['tid'], $tids)) {
$display_compare = TRUE; // display if node has at least one of specified terms
break;
}
}
if ($display_compare) {
print flag_create_link('compare', $node->nid);
}
?>
Please don't forget to replace "TERM_FIELD_NAME" with your field name and "1, 2, 3" with your list of tids.

I'm using wordpress and my page has the URL http://proservicescontractors.com/services/
But when I go to the page in my dashboard with the above URL, any change I make does not show on the front end. I tried simply duplicating my content and that change did not show on the front end.
Not sure what to do, this has me completely baffled.
Any ideas?
Since they're custom post types, by default, they're not actually loaded into a page per se. You should read up on WordPress's template hierarchy. To give you a rough idea of what's happening:
WP looks at your URL, and since it recognises it as a custom post type archive, it will look for a template to use...
It will first look for archive-$post_type.php, or in your case, archive-services.php
If it can't find that, it will look for archive.php
If it can't find that, it will use index.php
The important thing to note is that archive pages don't actually show up in the admin area, since they simply gather up and display custom posts, so there's nothing for you to edit.
Now, if you really want to edit some content on the Services archive, you have two options:
Edit archive-services.php in a text editor.
This is the quick and dirty option; the downside is that it defies the point of a CMS.
Create a page template with it's own loop
Create a new page template called page-services.php and insert a loop in there to display your custom posts. To get you started:
<?php get_header(); ?>
<?php // The main loop
if (have_posts()) {
while (have_posts()) {
the_post();
}
} else {
echo 'No posts';
}
?>
<?php // Now for the services loop
// WP_Query arguments
// For additional options, see: https://codex.wordpress.org/Class_Reference/WP_Query#Parameters
$args = array (
'post_type' => array( 'services' ),
);
// The Query itself
$query = new WP_Query( $args );
// The Loop
if ( $query->have_posts() ) {
while ( $query->have_posts() ) {
$query->the_post();
// Do something with the post
// In your case look at archive-services.php and see what
// that template does inside the loop
}
} else {
// no posts found
}
// Restore original Post Data
// Don't forget this, it's important
wp_reset_postdata();
?>
<?php get_footer();?>
You should then be able to apply that page template to your Services page; it should then display your posts below the page content. One thing to look out for is that WordPress will continue to load archive-services.php whenever you go to http://proservicescontractors.com/services/. While there are ways around this, the easiest fix would be to simply give your new page a different url, such as http://proservicescontractors.com/all-services/
Thanks for your help. I'm using yoast and I wanted to change the title and description. When you pointed out that it was a custom post type archive and not a page, I went back through yoast and found where I could change them under "Titles and Metas" > "Custom Post Type Archives" > "Services"
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 = $field_output;
}
}
}
}
Have you tried using Semantic Views? https://drupal.org/project/semanticviews - that way you can override the classes within the UI instead of template files, may suit your needs better.
I am trying to get the index-page of a Wordpress-blog show some very specific posts. As far as I understand i need to use a standard loop in order to make sticky posts work, so custom queries is out of the question. (Correct me if this is wrong.)
All posts are put in a main category (Eg. "Make-Up") In addition, posts that should show on the front page gets an additional category "Frontpage".
The current loop outputs all posts, regardless of category. And styles certain categories differently. An example would be the video-category which is only shown by getting an embed code from a custom field in the post.
<?php elseif (in_category('20')) : ?>
<div class="post element grid_4">
<?php echo get_post_meta($post->ID, 'Embed', true) ?>
</div>
I need to remove all posts not in the category "Frontpage" while still being able to control how posts are being shown.
Earlier i used a filter to control the main loop:
function exclude_category($query) {
if ( $query->is_home ) {
$query->set('cat', '20 27');
}
return $query;
}
add_filter('pre_get_posts', 'exclude_category');
However this would cause my geomashup-plugin to break as it probably uses the same loop?
My current proposal for a solution would be to do something like this, plus functioning code:
<?php elseif (the post is in BOTH category 20 and 27)) : ?>
<div class="post element grid_4">
<?php echo get_post_meta($post->ID, 'Embed', true) ?>
</div>
<?php else : ?>
<div style: display: none;></div>
However i am unsure about how make a condition demanding the post to be in two categories, and i realise this is a terribly dirty fix.
Any tips or pointers as to how i could solve this would be greatly appreciated :)
Front page can be seen here: http://parfymelle.brandbase.no
For anyone wondering i solved it by including the geotagged posts-category (the shop locations) in the filter for the main loop, and then using a php if in the index.php to hide posts from that category. Dirty, but works, i guess.
I'm trying to create two views.
View-1 is a list of nodes.
View-2 is an image gallery associated with each node.
I basically want to pass the node title from View-1 to a programmatic View-2, so that each row in View-1 will load View-2(with a result set filtered by the title of View-1!).
I'm confused about the approach. Should this happen in a custom module, preprocess functions, or some combination thereof?
I run into this a lot - wanting to pass an argument from a primary view to a secondary view that displays with each result.
I realize that the question is a bit general, but I'm curious how folks with more experience would approach this problem.
I've done this before on D6 where basically I just create a couple template tpl.php files for my View-1.
Inside my View-1 template for Display Output (views-view--default.tpl.php in D7 now)
I would simply programmatically find the value passed or returned by View-1 for this row.
In your case on each row you would check to see which node is returned by View-1 and then I'd add code in my View-1 template to programmatically load View-2 based on the current View-1 row (ie. node in your case.)
Make sense? 5 months late on the response but I was looking for a refresher and seeing if there's a better way to do this now in D7.
UPDATE:Just did this on my new D7 install. As an example I'll explain how it relates to my Ubercart implementation.
Ubercart, when installed, has it's main "home" shop page located at mysite.com/catalog
This page, when loaded, calls a View created by Ubercart called uc_catalog_terms. It is a taxonomy based view and all it does is grab all your Catalog taxonomy categories and render them.
E.g
As a clothing store, when you navigate to mysite.com/catalog, all you'll see at this page is a grid structure like:
Sweaters Shirts Jeans
My requirement was that I needed to show the shop catalog categories/terms on this page, but ALSO show 3 random products (images) from that category/term below it each catalog category.
E.g
Sweaters
Random Sweater #1 - Random Sweater #2 - Random Sweater #3
Jeans
Random Jean #1 - Random Jean #2 - Random Jean #3
How is this accomplished?
I created my own brand new custom view (no page or lock, just default) which grabs 3 random product images based on a taxonomy term ID argument and renders 3 linked product images. I'll call this custom view random_catalog_items. If 15 is the term ID for Sweaters, when this view is called with the argument 15 it will only render 3 random linked sweater product images.
I now went back to uc_catalog_terms view and created a views-view-fields--uc-catalog-terms.tpl.php (Row Style Output) template file.
THE DEFAULT VIEW VERSION OF THIS FILE (BEFORE MODIFICATION) IS:
<?php foreach ($fields as $id => $field): ?>
<?php if (!empty($field->separator)): ?>
<?php print $field->separator; ?>
<?php endif; ?>
<?php print $field->wrapper_prefix; ?>
<?php print $field->label_html; ?>
<?php print $field->content; ?>
<?php print $field->wrapper_suffix; ?>
<?php endforeach; ?>
THE MODIFIED VERSION BECOMES:
<?php foreach ($fields as $id => $field): ?>
<?php if (!empty($field->separator)): ?>
<?php print $field->separator; ?>
<?php endif; ?>
<?php print $field->wrapper_prefix; ?>
<?php print $field->label_html; ?>
<?php
$title = str_replace('/','-',strtolower($field->raw));
print '<img src="'.drupal_get_path('theme','my_theme').'/images/catalog/'.$title.'-header.png" />';
print '<hr style="width: 100%; background: #000; height: 2px; margin-top: 3px;"/>';
// get the taxonomy term ID
$tid = $row->tid;
// render the 3 random items
if ($random_products = views_get_view('random_catalog_items' )) {
print $random_products->execute_display('default', array($tid));
}
?>
<?php print $field->wrapper_suffix; ?>
<?php endforeach; ?>
So as you can see inside the first View, for every row that is rendered I get the current taxonomy term ID being shown through the available row result object - $row->tid and then I simply call my created view for each row, passing along this Term ID as the argument for it. I leave a lot of the default code in there but inside my view configurations the LABELS and such are set to HIDDEN so they don't even render anyway.
In your case it should be very easily adaptable to just pass a Node NID instead of a Taxonomy Term ID.
VOILA IT ALL WORKS! View within a View! Hope this helps :)
It helps to have the Devel module loaded since then inside these View templates you can debug and see what variables are available to you via something like print krumo($row).
Personally I would avoid views here alltogether.
A simple module using a hook_menu to define the menu-items and two simple menu-callback-functions dealing with the required parameters.
The alternative would be to make all the custom parameters and custom query-filtering and tables known to views.
My (pseronal) rule of thumb is:
If you are certain you will re-use the code several times in future projects a view-addon is worth the investment.
If you will use the views-interface for more then one-time-setup (the general use) e.g. define or change views in an editors/webmasters workflow this makes sense.
The basics of this is really simple and most probably a lot less coding and development then writing the views extensions.
/** Implementation of hook_menu().
*/
function gallery_menu() {
$items = array();
$items['gallery'] = array(
'title' => 'Gallery',
'page callback' => '_gallery_list',
'access arguments' => array('access content'),
);
$items['gallery/%gallery'] = array(
'title' => 'For dynamic titles, see title_callback documentation',
'page callback' => '_gallery_view',
'access arguments' => array('access content'),
);
return $items;
}
/** Load a gallery from database. Name follows %parameter_load hook.
*/
function gallery_load($id) {
return db_query("SELECT * FROM {galleries} WHERE id = %d", $id);
}
/** Render a list of galleries.
*/
function _gallery_list() {
$html = "";
$galleries = pager_query("SELECT * FROM {galleries}", 10);
foreach($galleries as $gallery) {
$html .= check_plain($gallery->title); //You would actually build vars here and push them to theme layer instead.
}
$html .= theme("pager");
return $html;
}
/** Load a gallery from database. Name follows %parameter_load hook.
*/
function gallery_load($id) {
return db_query("SELECT * FROM {galleries} WHERE id = %d", $id);
}
/** Render a list of galleries.
*/
function _gallery_view($gallery) {
$html = "";
$images = pager_query("SELECT * FROM {images} WHERE gallery_id = %d", 10, $gallery->id);
foreach($images as $image) {
$html .= check_plain($image->title); //You would actually build vars here and push them to theme layer instead.
}
$html .= theme("pager");
return $html;
}
Obviously, as stated in the comments, you would additionally create a few theme functions to handle the rendering, to 1) avoid hardcoded spagetty-HTML all over your module and b) allow the frontenders to stay in their theme when creating the HTML.
This sounds like a good opportunity to use an ajax callback. You could have your primary view on a part of the page just like normal and a secondary view in a custom block or something. when focus lands on the primary item (in the form of a button click or hover or something) you can use an ajax callback to replace the content of your custom block with the secondary view using your argument.
are you using drupal 6 or 7 for this? my understanding is that they do this is different ways.
I'm looking for a plugin (or better yet, not a plugin) for wordpress that lets me generate standard content elements, or includes for posts and pages.
For example, my_content_1 could be:
buy it now for $23!!
Which could then be included in posts and pages using some kind of syntax (or whatever) like:
Welcome to my site, blah blah blah.. check out this product - %my_content_1%
Not looking for anything fancy, anything that does this sort of thing would be awesome.
The point of this being much like a regular php include I could have the same information updated in one place and applied over many pages/posts.
I found something that is pretty much what I'm looking for:
http://wordpress.org/extend/plugins/reusables/
However, other suggestions would be good as I'm not too confident in the quality of the code for that plugin.
Not sure about a plugin, but how about simply creating something yourself? If you created a PHP page and set up variables such as
$content->title = "This is a title"
$content->smallText = "Insert some short paragraph here"
And then just include it in your header? You could store it in your theme directory and then call it like so
<?php $themeFolder = get_bloginfo("template_url"); ?>
<?php include($themeFolder."/content.php") ?>
Would that be suitable?
How about creating a few files and link them in using shortcode?
ie: open your themes/functions.php file add this..
<?php
function wp_my_shortcodes($atts)
{
extract(shortcode_atts(array(
'type' => '', //author, rss, adverts
), $atts));
switch($type) {
case 'author' : $display = wp_display_author_info(); break;
case 'rssview' : $display = wp_display_rss_info(); break;
case 'adverts' : $display = wp_display_adverts(); break;
default : $display = wp_display_author_info(); break;
}
return $display ;
}
add_shortcode('mycontent', wp_my_shortcodes);
function wp_display_author_info()
{
include(TEMPLATEPATH.'/my_author_info.php');
}
function wp_display_rss_info()
{
include(TEMPLATEPATH.'/my_rss_info.php');
}
function wp_display_adverts()
{
include(TEMPLATEPATH.'/my_adverts.php');
}
?>
using shortcodes inside your posts you can then bring in which ever piece of content that you want.. in the example above I've created 3 pages in the template root folder called
my_author_info.php, my_rss_info.php, my_adverts.php all of which speak for themself..
my_author_info.php
this page could use the the_author_meta() to populate a div box with included author info,
my_rss_info.php
include your subscription box to let users subscribe to your blog
my_adverts.php
include 4x 125x125 adverts?
so in the post i could use
[mycontent type='author']
[mycontent type='rssview']
[mycontent type='adverts']
if no argument is added to the shortcode then the default view is shown, in this case..
[mycontent]
would return the authorview as default...
this would then include that file in the content...
just remember to create the included files :)
