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.
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.
