Prints a breadcrumbs trail.
This is a modded version of the original breadcrumbs tag with additional functionality. It allows defining a starting level as the menu tag.
Additionally, there is an option to render the class with increments for each block: <... class="breadcrumbs1">, <... class="breadcrumbs2">, ..., <... class="breadcrumbsn"><span...>... and so on.
How do I use it?
Just insert the tag into your template/page like: {jmbreadcrumbs}
Another example: {jmbreadcrumbs classid="breadcrumbs" inc_classid="true" start_level=1 starttext="You are here" root="Home" delimiter="" assign_count="jmbc_inc_id_count"}
The number of iteractions can be found in a smarty variable: $jmbc_inc_id_count
This would allow you to code your css with something like this:
[[if isset($jmbc_inc_id_count)]]
/* assign starting values */
[[assign var=\'Grad_r\' value=80]]
[[assign var=\'Grad_g\' value=90]]
[[assign var=\'Grad_b\' value=85]]
/* assign step value */
[[assign var=\'c_step\' value=-5]]
[[section name=jmbc_id start=1 loop=$jmbc_inc_id_count]]
.breadcrumbs[[$jmbc_inc_id_count-$smarty.section.jmbc_id.index]]{
background-color: rgb([[$Grad_r]]%,[[$Grad_g]]%,[[$Grad_b]]%);}
[[assign var=\'Grad_r\' value=$Grad_r+$smarty.section.jmbc_id.index*$c_step]]
[[assign var=\'Grad_g\' value=$Grad_g+$smarty.section.jmbc_id.index*$c_step]]
[[assign var=\'Grad_b\' value=$Grad_b+$smarty.section.jmbc_id.index*$c_step]]
[[/section]]
.lastitem{
background-color: rgb([[$Grad_r]]%,[[$Grad_g]]%,[[$Grad_b]]%);}
[[/if]]
div.jm_breadcrumb{background-color:#cce6d9;}
There are, probably, better ways to code this but it works... :)
Anyway, this is only an idea... other crazy things can be done.
Also meant to be used with Babel multi language solution, by giving a start_level parameter which should be set to 1 to hide the odd link at the beginning of the breadcrumbs.
If you use use_list=1 the plugin overrides the default behavior and renders an unordered HTML list, enabling you to use some of the CSS breadcrumbs styling found around the WWW.
What parameters does it take?
- (optional) delimiter - Text to separate entries in the list (default ">>").
- (optional) initial - 1/0 If set to 1 start the breadcrumbs with a delimiter (default 0).
- (optional) root - Page alias of a page you want to always appear as the first page in
the list. Can be used to make a page (e.g. the front page) appear to be the root of everything even though it is not.
- (optional) root_url - Override the URL of the root page. Useful for making link be to \'/\' instead of \'/home/\'. This requires that the root page be set as the default page.
- (optional) classid - The CSS class for the non current page names, i.e. the first n-1 pages in the list. If the name is a link it is added to the <a href> tags, otherwise it is added to the <span> tags.
- (optional) currentclassid - The CSS class for the <span> tag surrounding the current page name.
- (optional) starttext - Text to append to the front of the breadcrumbs list, something like "You are here".
- (optional) assign - Assign the results to the named smarty variable.
- (added)(optional) start_level - works like in the menu tag (default 0).
- (added)(optional) inc_classid - true/false or 1/0. Renders an incremental number appended to the classid. Doesn\'t affect currentclassid. (default false).
- (added)(optional) assign_count - Assign the number of iteractions ocurred in incremental classid to the named smarty variable.
- (added)(optional) use_list - true/false or 1/0. Overrides the default behavior and renders an unordered HTML list.
