On my Drupal7 have a views (results) width a exposed filter for list the nodes.
When click on a node then display a breadcrumb
ex.
Home >> results >> node-title
Thats good!
But i will make the breadcrumb 'results' a backlink.
When input ex. t then the url is:
http://www.site.com/results?title=t
I try the above url as variabele in the 'results' breadcrumb.
I hope you understand this.
Is this possible with a php snippet in custom breadcrumbs?
Yes this is possible :)
The tricky part here is having your code "remember" what the query was from the list of nodes. One option would be to add a $_GET parameter to all of the node links.
For clarity:
If you are on
http://www.site.com/results?title=t
A link to a given node on that list of results would be:
http://www.site.com/node/56?title=t
This can be done in views by modifying the output of the link. Shouldn't be too hard.
Then, to modify the breadcrumbs you need to add a function like this to template.php
function THEME_NAME_breadcrumb($variables) {
$breadcrumb = $variables['breadcrumb'];
// check to ensure this is the one you want to alter
// Custom rebuild process of breadcrumb with custom links.
if ($breadcrumb[1] == 'your_breadcrumb_id') {
// Keeping the trail/current page as non linked
$links[1] = l(t('results'), 'results', array('query' => array('title' => $_GET['title'])));
drupal_set_breadcrumb($links);
}
}
(Check my code for syntax, its untested)
Good luck!

I am trying to make a plugin that will display custom page when a parameter is present in the URL. For example, let's say that the URL of a post is localhost/wp/2018/03/22/postname/, it displays post normally as expected. What I want to achieve, is when I specify URL as localhost/wp/2018/03/22/postname/?param=1, I want to display page that I will generate with the plugin. I made a function that works when the parameter is present and it echoes some example content, however, it merges with what WordPress normally displays. So when I put the parameter into URL I get a regular page with post and my content somewhere in the middle. I want to display only the page that i generate from scratch, from <html> to </html> with my plugin. How can I do that?
There is a filter in WordPress called template_include this filter is executed before any output is displayed on the WordPress generated page.
You can override the current template via this filter as soon as you find the parameter and value in the URL. E.g. below is a filter I was using in a project to override archive & single template for a certain CPT:
function em_templates($template) {
if(get_query_var('post_type') == 'xyz' ) {
return FMM__DIR__ . '/templates/archive-xyz.php';
}
return $template;
}
add_filter('template_include', 'em_templates', 1, 1);
You can adopt this logic for parameter and use this WordPress filter to take over the template process and display yours own.
Was just wondering if there is a way to create a custom variable so that I can add my custom variable created in the Meta title of the page.
Yoast SEO has a list of variables predefined here.
It would be great if I could create a variable of my own. Is there any way to get this?
Thanks in advance!
You have two options for this.
Add filter for change exist variable.
Add your new custom variable.
If you want to change exist variable, you can do it like this:
// define the wpseo_replacements callback
function filter_wpseo_replacements( $replacements ) {
if( isset( $replacements['%%page%%'] ) ){
$replacements['%%page%%'] = 'Page x of y';
}
return $replacements;
};
// Add filter
add_filter( 'wpseo_replacements', 'filter_wpseo_replacements', 10, 1 );
And if do you want to add custom variable you can do it like this:
// define the custom replacement callback
function get_myname() {
return 'My name is Moses';
}
// define the action for register yoast_variable replacments
function register_custom_yoast_variables() {
wpseo_register_var_replacement( '%%myname%%', 'get_myname', 'advanced', 'some help text' );
}
// Add action
add_action('wpseo_register_extra_replacements', 'register_custom_yoast_variables');
I hope I was helpful to you.
There is a way, but as far as I know, you must get a Premium account in Yoast Seo. One of the most important functions of both Yoast SEO and Yoast SEO Premium is the possibility to add title templates and meta description templates to the homepage, all (custom) post types, all (custom) taxonomies and other pages.
Note: Template variables can also be used on individual posts, pages and taxonomies.
Setting up / changing your templates
You can change your title & meta templates by going to the admin of your WordPress installation and clicking SEO → Titles & Metas.
Log in to your WordPress website. When you're logged in, you will be in your 'Dashboard'. On the left-hand side, you will see a menu. In that menu, click on 'SEO'.
The 'SEO' settings will expand providing you additional options. Click on 'Titles & Metas'.
Under each tab, you can use these variables to create templates for various pages within your site.
You can use the variables from the partial list below to create your own templates for the titles and meta-descriptions. The full list of variables is listed on the HELP tab of the plugin. Just go to SEO → Titles & Metas and click the help tab in the top right.

I have the problem that I am using a theme where the navigation is simply 'scrolling' to a given part (eg. #contact) when pressed. However, I have implemented some seperate subpages that exits this scrollable page and thus renders the navigation ineffective.
My question is, how can I change the destination of my links or maybe change the menu entirely when users are on these subpages?
I should clarify that all the pages that need 'the new' navigation use a different page template called full_width.php. But since it is using an include header function I can't just replace the navigation.
Thank you for your time!
Here is simple solution based on templates.
if ( is_page_template('full_width.php') ) {
//menu for full width page
} else {
// Returns false when 'full_width.php' is not being used.
wp_nav_menu( $args );//read for args in codex to make menu you want.
}
the website in question is right here I'm trying to generate a CSS dropdown, however no such option is available in wp_list_pages(), I also won't be able to get the desired effect using WP Menus in the appearance menu (I used this method to generate my footer links)
This is ideal:
I know how to generate the menu, I just don't know how to get it under the "cars" menu without a hack javascript solution.
The ideal solution involves targeting the list item by the template name "Car Showcase" and allowing me to generate PHP/HTML (The code needed to make the dropdown) after it. Does this make sense to everyone?
The actual way to create custom HTML for WordPress menu is to create a Walker
http://codex.wordpress.org/Function_Reference/Walker_Class
Can you not just create another menu and pull it from:
wp_nav_menu( array( 'name' => 'menu-header'));
I extended the walker class in functions.php, it was way dirtier than it should be, and I'm still targeting the list item being generated by an ID, a solution which I am not fond of, but this is the cleanest solution I can come up with until I find a better one.
class Dropdowns extends Walker_page {
function end_el(&$output, $item, $depth=0, $args=array()) {
if ($item -> ID == 55) { //checks if the page id is the list item I want to make my dropdown under
$vehicles = query_posts('post_type=vehicles'); //my custom post that I want to dropdown
if ($vehicles) { //check for no entries
//code for drop downs go here
}
}
}
}
My employer requires certain pages on the website have a two page feature.
What this means is that some default content show up on the node_view page as normal but the second part should show up when a link is clicked.
This will be easy if I could do this across multiple nodes but the requirement is for all the data to be stored in one node but displayed across two pages.
I hacked together the following code:
function mymodule_node_view($node, $view_mode, $langcode){
$path = current_path();
$path_alias = drupal_lookup_path('alias',$path);
$links = array( 'test' => array('title'=>'my_link', 'query'=>'', 'href'=>"{$path_alias}/nextpage") );
$node->content['my_module'] = array(
'#theme' => 'links__node__mymodule',
'#links' => $links,
'#attributes' => array('class' => array('links', 'inline')),
);
}
That creates a hyperlink called my_link across the top of my content area - which is great.
The problem starts when I click the hyperlink. Supposing I am on http://example.org/homepage and I click the hyperlink, I expect to be redirected to http://example.org/homepage/nextpage. Also, I still want to maintain the view and edit tabs of the actual node I was on. However, Drupal correctly gives me a "page not found" error.
What's interesting is if I used http://example.org/node/1 and visited http://example.org/node/1/nextpage, I don't get the issues I described above but the url is less descriptive.
To solve this problem, I am sure I have to extend hook_menu but I don't know how to account for any number of taxonomy terms leading up to the actual node title. So, I can't predict how many % I will need before the node title and then my /nextpage. However, I want /nextpage to still have the view and edit tabs of it's parent page.
This is all unexplored territory for me.
Update
I found the following function which does a great job of returning the entire node path complete with taxonomies:
$path = current_path();
$path_alias = drupal_lookup_path('alias',$path);
What I don't know is how to take advantage of this in hook_menu to dynamically create /nextpage for my nodes.
Please remember, I don't really want /nextpage to be entirely independent of the original and actual Drupal node. When on /nextpage I want to be able to have access to the view, edit etc tabs of the node.
So, /nextpage effectively is just an extension of a Drupal node page.
There is a quick way to do that. Using views module.
In the fields section choose the field you wanna view. And in the arguments add the nid.
Then add the link to the node view you already created.
The final result http://mysite/views-page/[nid]
Hope this helps... Muhammad.
I would check the node_menu() function to get some reference on how it's implemented.
Not sure on your taxonomy requirements so this might be insufficient but I'll go with what I understand.
But off the top of my head I'd go for something like:
function mymodule_menu() {
$items['node/%node/nextpage'] = array(
'title' => 'Next page',
'type' => MENU_LOCAL_TASK, // Makes it a tab on node/%node-pages
'page callback' => 'mymodule_node_page_view', // Your page display function
'page arguments' => array(1), // First will be a node object, second will be whatever value is passed in the url
// You should rip access callback and access arguments from node_menu()
);
return $items;
}
That should do something like what you are asking for.
It is also possible, easier and definitely recommended to do this with Panels/Pages (see also Chaos Tools) or arguably Views as they are quite capable of all this and generally a better way to work with Drupal's strengths than custom code.
Updated
To clarify I've simplified the menu hook and you should be able to use the below page view function. I still believe you would make a better solution using Panels and overriding node_view and such.
The MENU_LOCAL_TASK part in the menu hook should turn this into another tab along with View and Edit.
function mymodule_node_page_view($node) {
die("It works: ".$node->title);
}
Hope that's more helpful.
