Automatically Make Paths Lowercased

This should be pretty straightforward, but I'm concerned that it might cause problems with other paths. I'd hate to add yet another setting/preference to the module just to toggle lowercasing. I'll think about this one for a bit...

koro,

Have you consider to theme your breadcrumb instead? Put the code snippet below in your template.php file.

function phptemplate_breadcrumb($breadcrumb) {
  if (!empty($breadcrumb)) {
    return '<div class="breadcrumb">'. strtolower(implode(' » ', $breadcrumb)) .'</div>';
  }
}

If anyone else is interested I just had to do the same thing and I just added a strtolower (string to lower) so that function custom_breadcrumbs_nodeapi became

function custom_breadcrumbs_nodeapi($node, $op, $teaser, $page) {
  if ($op == 'view' && !$teaser && $page) {
    if ($breadcrumb = _custom_breadcrumbs_load_for_type($node->type)) {
      $titles = explode("\n", $breadcrumb->titles);
      $paths = explode("\n", $breadcrumb->paths);

      $titles = module_exists('token') ? token_replace($titles, 'node', $node) : $titles;
      $paths = module_exists('token') ? token_replace($paths, 'node', $node) : $paths;

      $trail = array(l(t('Home'), ''));
      for ($i = 0; $i < count($titles); $i++) {
        // skip empty titles
        if ($title = trim($titles[$i])) {
          $trail[] = l($title, strtolower(trim($paths[$i])));
        }
      }
      drupal_set_breadcrumb($trail);
    }
  }

}

Custom breadcrumbs rules by the way. How else would I ever get my crazy directory location view to end up on a single node without anyone being able to tell I went from view to node? This made the complex oh so simple.

I wish this worked for me, but it doesn't seem to (this solution just above, to change the module). Perhaps I'm doing something wrong?
I'm using the zen_basic theme, in case that's relevant.

The solution slightly farther above (to add a function to template.php) works fine to make the breadcrumb appear lowercase, but I can't seem to figure out how to make the link itself lowercase for Category terms that are uppercase.

Do you have any other ideas?

Thanks in advance!
:)

you can use CSS to change case

avolve – this issue just above was about making categories appear lowercase in the URL (when added using token)... not about the breadcrumb display, which you're right, can be changed with css.

This is a bit of an old issue at this point, and I wonder if it has been solved since? Personally I have had to use a different solution (than using categories in the url) because this didn't work for me.

Any advice is welcome :)

my mistake, sorry. Only skimmed through this looking for guidance on another issue (views breadcrumbs).

Thank you Jody Lynn, your code worked for me(Drupal version: 6.8). I used only strtolower(trim($paths[$i])) part. Other solutions(CSS and template.php hack) lowercase both link text and URL, but Jody's code lowercases only URL.

I want to share how it worked:

In custom_breadcrumbs.module file, in function custom_breadcrumbs_nodeapi($node, $op, $teaser, $page) function, i changed the code part trim($paths[$i]) as strtolower(trim($paths[$i]))

That's all.

I would not prefer to change any module code; but i tried a lot of things and code hack was the only way. :(

I also want to thank to Eaton for this nice module.

Upss!

It did not work for Turkish paths/terms. Jody's code might still be useful for some issues, but for terms, i realised a better way. No code changes, no another hacks(so i reverted the module file). The solution was there already. My mistake :(.

Solution is to use [termalias] token for path, not [term] or [term-raw]:

Titles: [term]
Paths: [termalias]

PS: Module version: 6.x-1.4

Tbarregren: that code whitescreens my site.

After googling my face off, here is how I did it, code-free...

1. Install pathauto if you haven't already. Get into the pathauto settings...
Site building › URL aliases › Automated Alias Settings (how confusing is it to have Pathauto labeled "Automated Alias Settings"?)

2. Under "punctuation settings", change "Slash /:" to "no action". Otherwise, your paths will remove forward slashes andyoururlstructurewilllooklikethis.

3. Then go to the custom breadcrumbs page and make them look like this (for example)...

<pathauto>|whatever/[term-raw]/[title-raw]

The <pathauto> part tells Custom Breadcrumbs to apply the rules set in pathauto to the breadcrumbs. If you just use "whatever/[term-raw]/[title-raw]", and don't drop in the <pathauto> deal, you'll get caps. If you don't change the punctuation settings (the "Slash /:"), the urls will be smooshed together with no slashes.

4. Make sure not to use slashes in your titles (not sure why you would anyhow), or else you'll have bogus url structure.

I feel like this should be made a bit easier, no? or perhaps they should be lowercase by default?

N1ckhead's solution is for 6.x version - not 5.x-1.2 (which is the version the issue is raised for).

A solution for 5.x-1.2 is to change line 59 in custom_breadcrumbs.module from:

           $trail[] = l($title, trim($paths[$i]));

to:

          $trail[] = l($title, trim(strtolower($paths[$i])));

The 5.x branch is no longer supported.
