I haven't quite the right process to change the body classes based on the page being viewed.
I have about 20 or so pages within a subsection that all have a different background color and reversed nav links from the main site.
I can't figure out if there is some kind of preprocess function to use (and which) in template.php or if I should do something specifically in the certain xx-page.tpl.php file.
Just adding an ID to the body tag in the xx-page.tpl.php isn't reliable due to browser caching.
I've seen this snippet:
if (drupal_is_front_page()) {
$vars['body_class'] .= ' home';
}
however, "is it the front or not" isn't enough because it's also not just a page, it's a specific page but I've either missed the syntax or am doing something wrong.
Is this a case where I need to create a custom function and if so, is the template.php page where it goes?
also, I'm in Drupal 6.26
Thanks
Are you looking for this function?

You might also want to have a look at the Context module.

I've a weird issue in my Drupal 9 website where a couple of regions (subfeatures and footer) get rendered differently in different pages with no consistent behavior.
They are loaded via the theme's default page.html.twig and should render inside the page js-layout wrapper as in below screenshot
But in some pages, it gets rendered outside the wrapper like in the below screenshot
This is simple website with no overrides on the theme level for the regions so this is quite strange
Without knowing the theme, it is difficult to give an answer. (Which theme is used, which templates (which Twig file provides the theme) and so on...
But let me try to give you a starting point:
Check all twig files of your theme
If there is a multiple for page, like: page.html.twig & page--article.html.twig. Then check the HTML structure for it
Check the region's conditions
In the page-twig templates, check if the HTML closing tags depend on the region conditions. Is there a condition that the div sometimes closes earlier?
I hope this will help you.
What would be the proper procedure for accessing the current page html data and picking up all of a certain tag and throwing them into the sidebar as links?
I'm not sure your proficiency with php, but I'll give you and overview of what you'd probably want to do.
First, you need the HTML. I'm assuming you're running this on a page (in a page.php file or single.php file, or similar), this means that you have access to the global variable $post, which contains the html of the page in it. To access it you can use the helper function get_the_content(), this returns the html being displayed.
Next you need to parse through this to get the h2 tags. A simple regex can handle this, something like <h2[^>]*>(.*)</h2>. It's important to remember that this regex is very picky, so format your html correctly, no multiline h2s.
So now you have the html, and have parsed it with a regex to get the h2s. Now you need to generate the list from the results, and prepend it to the top of the content of the page. There are a ton of ways to do this, the easiest being just running the code in the right spot in the template file.
Of course there are probably better ways of doing this, I'd recommend you look at say a FAQ plugin (if that's what this is for), or do the lists manually (as this system can be broken), or possibly use a custom post type; but for your question, that's how I'd do it.
I have a dynamic PHP stylesheet, but I can't find a way to send variables to it so I used sessions instead. Figured this kinda sucked, so I'm going to give it another try but could need some help. It's an external stylesheet where a variable has effect through the whole document.
You probably want to use an embedded stylesheet (a <style> block) in the page: it increases the size of the main page, but solves the variable access issue without needing sessions and reduces your number of requests. You can just load your dynamic stylesheet into the main page's view using load->view.
EDIT: Ah, massive amounts of CSS would be one problem. Well, two alternatives are to:
Turn on the $_GET support in your CI install, you COULD pass in a request parameter in the CSS link and then check for the request parameter in the PHP controller or view file that generates the actual CSS. Not visually the tidiest option, but it does work.
Put in a cookie that you check in the controller that gets called for the CSS: you can then check that in the controller or view and do the right thing. Visually much tidier than the request parameter option, but a bit more involved.
I am setting up my first drupal (6) site and so far I like the system.
I've now run into a problem however: to give the content more space I want to hide the right-sidebar (with the navigation menu etc.) on every page from a specific module (or also fine: for a specific node/view from the module)
The only way I've come up with is to add some CSS to the module CSS files, but this doesn't seem very clean to me since I would need to redo it on every update (also the module uses 5 CSS files for different views)
Is there a better way to do it?
To be clear: I don't want to just hide a block, I want to hide the whole sidebar
Hmmm. Is this a custom module or something commonly available? Some modules allow you to create custom tpl.php files (see the theming guide) for them. This might quickly solve your problem.
If you are theming a node, then it is significantly easier. You can theme a specific type of node by naming convention (again via .tpl.php files in your theme). You can check out how to do that here.
Definitely check out the theming guide, since you will probably want to create your own theme instead of hacking on one of the core themes (not recommended). Typically you can copy /themes/garland into /sites/all/themes/my_garland, switch your site's theme to that and then make whatever changes you need (otherwise you'll have to reapply changes every time you update core).
Finally, you can check for path arguments (which seemed weird to me at first) if you want to do things in PHP that are more complex (see the arg function). If this is your first Drupal site, you may also need to know how to include css programatically.
Good luck! Drupal is a fun and interesting product.
You can configure the block visibility for each individual block and path in your website (admin/build/block). Under 'Configure'/'Page specific visibility settings'/'Show block on specific pages' you can set the navigation menu block not to be displayed for some specific routes. If a sidebar has no blocks to display it will hide itself allowing more space for the content.
You could use the Context module, with it you can, among other things, set rules for each block/menu where and when i should be shown (or not). You could also do this the way Josep explained but with Context you get more options.
And as Josep said when there are no blocks active in the sidebar it should disappear automatically, if not check your page.tpl.php it should have something like this in it:
<?php if ($right): ?>
<div id="sidebar-right">
<div id="sidebar-right-inner"> <?php print $right; ?> </div>
</div>
<?php endif; ?>
So if there is nothing in the Right region it doesn't display the sidebar. Maybe you have to change the name of the region, depending how they are called in you template.
I believe you already got the answer or a way to fix your problem.
There is a simple way to fix your problem. Here's a link.
I need the node titles to be able to display some text formatting.
As far as I understand, Drupal's title field is just plain text, it doesn't allow HTML or any other input format. Is that true? Is there a way to override this, or another solution?
I am working with Drupal 6.
You can pretty easily do this in your theme, there are different ways to do with. The simplest would probably to do it in your template.php
/* this function generates the variables that are available in your node.tpl,
* you should already have this in your template.php, but if not create it
*/
function mytheme_preprocess_node(&$vars) {
// It's important to run some kind of filter on the title so users can't
// use fx script tags to inject js or do nasty things.
$vars['title'] = filter_xss($vars['node']->title);
}
What happens in the function is that it overwrites the default value for $title in the node.tpl which holds the variable used for the title. It is usually placed within a h1 or h2 tag, so you should be aware of that. The filter_xss is used to only allow basic html tags, so protect the site, you can look at that function here. That are some other filter functions, like check_markup, and filter_xss_admin, but you can give a second param for filter_xss which is an array of allowed tags, so should the default not be good enough, you can just change it to fit your needs.
Use function mytheme_preprocess_page for D7.
Extending the module mentioned by wiifm, for D7 there is now also: https://drupal.org/project/html_title_trash
It allows more tags and also works for block titles, rather than just node titles.
