Breadcrumb module

[sucresemoule]

I developped a small breadcrumb module based on code by Ryan and some other code from templates and other modules...

http://goliwok.com/jm/wbaker/breadcrumb.zip

It generates (like all not cached breadcrumbs) a lot of sql queries

I will add a smarty version soon to make it faster.

Instead of using my old create_breadcrumbs code, you should rather utilize the new page_trail sql entry. It stores the same information as $bca.
Other than that: thanks for converting it into a module!

Thanks for this nice module. I have a question. When I am on this page:
http://www.domainname.nl/wb/pages/welkom/nogmaals-welkom.php the breadcrumb shows like this:
Home  : Welkom  : Nogmaals welkom >>
I would rather have it displayed like  Home  : Welkom >>
and then comes the title of the page as I write it in wysiwyg. In most cases the "wysiwyg title" is the same as the page-title and this way I can prevent it from showing up two times.

E.G
Home  : Welkom  : Nogmaals welkom >>
Nogmaals welkom should read:

Home  : Welkom >>
Nogmaals welkom

I am gonna have a look on that page_trail thing.

[sucresemoule]

I added an option to show or hide the current page title.

Thank you!! Great!

is there any way to intregrate the breadcrumbs directrly into the template.

for example, the content is "<?php page_content(); ?>

[pcwacht]

Yes there is.

Copy this code to the top of your templates's index.php

Code:

<?php
function create_breadcrumbs($item) {
global $database;
global $bca;
$query_menu=$database->query("SELECT page_id,parent FROM ".TABLE_PREFIX."pages WHERE page_id = '$item'");
$page=$query_menu->fetchRow();
if ($page['parent']!=0)
create_breadcrumbs($page['parent']);
else $bca[]='0';
$bca[]=$page['page_id'];
}
function breadcrumbs($page_id,$sep=' > ',$tier=1,$links=true) {
if ($page_id!=0)
{
  global $database;
global $bca;
if (sizeof($bca)==0)
  Â  Â  Â  create_breadcrumbs($page_id);
$counter=0;
foreach ($bca as $temp)
{
if ($counter>=(tier-1));
  Â  {
  Â   if ($counter>$tier)
echo $sep;
$query_menu=$database->query("SELECT menu_title,link FROM ".TABLE_PREFIX."pages WHERE page_id=$temp");
$page=$query_menu->fetchRow();
if ($links==true AND $temp!=$page_id)
echo '<a href="'.page_link($page['link']).'">'.$page['menu_title'].'</a>';
else
  Â  echo stripslashes($page['menu_title']);
}
  Â  Â  Â  $counter++;
}
echo "\n";
}
}
?>

call it from within the template with

Code:

<?php create_breadcrumbs(); ?>

at the place you need the breadcrumb.

I don't know if this is old code. But this one works for me

Have fun,
John

@John, I copy & pasted you code into my index.php, but I get the following warning:

Warning: Missing argument 1 for create_breadcrumbs() in C:\Inetpub\wwwroot\wb\templates\stylish\index.php on line 114

Could you tell me what parameter I'm missing?



Secondly, as an observation, doesn't it make sense to put a breadcrumb trail in the template, rather than as a module?

[Stefan]

Please look directly at my script for a full documentation.
To call it, you need to use <?php breadcrumbs(PAGE_ID); ?>
and yes, I agree, this belongs into the template. That's what it was originally meant for.

[Leigh]

Thanks Stefan, I was missing the documentation at the beginning of the script. All is now working.

Shouldn't your code be put in the "Completed Code Snippets" section?

[Stefan]

Well, it's not really optimal anymore as there is now a way to achieve the same result with a couple less SQL calls. I have been wanting to rewrite it all the time...

[Argos]

Stefan, I would like to have a link to home in all paths, how can I do that?

So for example:  home > item3 > subitem2

[Stefan]

Just hardcode the part to the first '>'.

[Argos]

Just hardcode the part to the first '>'.

Ah! "just hardcode"
Well, I already figured out that that was the place to do something, but since I am no coder I have no clue what to write there. I want the "home" to be a link too, so just write "home" after echo will not do the trick I guess. Can you please tell me what to do exactly? Please?

[pcwacht]

Try:
<a href="http://someplacecalledhome">Home > </a><?php breadcrumbs(PAGE_ID); ?>

or simular in your template

Have fun!

John

[Argos]

Try:
<a href="http://someplacecalledhome">Home > </a><?php breadcrumbs(PAGE_ID); ?>

or simular in your template

Quite clever and so obvious that I didn't think of that. Works nicely ofcourse, however there is one small problem: on the homepage I have now "Home > Home"

So an adaptation to the breadcrumb script would be nicer...

[pcwacht]

Did have a wee look at breadcrumbs script

Doesn't seem like an easy adaption

Maybe something like this might work at template level

Code:

<?php
if (PAGE_ID==1) 
breadcrumbs(PAGE_ID); 
else
?><a href="http://someplacecalledhome">Home > </a><?php breadcrumbs(PAGE_ID); ?>

Change the number 1 to whatever your Home pageid is

Have fun!
John

[Argos]

Nope, that gives me 3 times "home" in a row

[pcwacht]

Maybe the if else need more structuring something like this:

Code:

<?php
if (PAGE_ID==1)  {
  breadcrumbs(PAGE_ID); 
} else {
  echo '<a href="http://someplacecalledhome">Home > </a>'. breadcrumbs(PAGE_ID); 
} 
?>

The logic,
You need the home added to every page except for the homepage
This is what the test does,
if page equals homepage just show the breadcrumbs, if not, show home plus the breadcrumbs

It should work.
