hahaha ok. Here is the thing:
I've spent a little time debugging it and when i put
return $crumbs at the end of the function it returns an array only with the first item. But the var_dump still does its job...
Code:
function bread_crumb ($page_id, $crumbs = array())
{
$page = $this->find_by_id($page_id);
$crumbs[] = anchor('pages/'.$page->page_id, $page->page_title);
$parent_id = $page->page_parent_id;
echo '<pre>';
var_dump($crumbs);
var_dump($page->page_id);
var_dump($parent_id);
var_dump($page->page_title);
echo '</pre>';
if ($parent_id > 0)
{
$this->bread_crumb($page->page_parent_id, $crumbs);
}
return $crumbs;
}
result
Code:
array(1) {
[0]=>
string(80) "buhu"
}
string(1) "5"
string(1) "3"
string(4) "buhu"
array(2) {
[0]=>
string(80) "buhu"
[1]=>
string(84) "Castelos"
}
string(1) "3"
string(1) "1"
string(8) "Castelos"
array(3) {
[0]=>
string(80) "buhu"
[1]=>
string(84) "Castelos"
[2]=>
string(83) "Turismo"
}
string(1) "1"
string(1) "0"
string(7) "Turismo"
array(1) { [0]=> string(80) "buhu" }
BUT when i put
return $crumbs conditionaly
Code:
if ($parent_id > 0)
{
$this->bread_crumb($page->page_parent_id, $crumbs);
}
else
{
return $crumbs;
}
then it returns NULL at the end:
Code:
array(1) {
[0]=>
string(80) "buhu"
}
string(1) "5"
string(1) "3"
string(4) "buhu"
array(2) {
[0]=>
string(80) "buhu"
[1]=>
string(84) "Castelos"
}
string(1) "3"
string(1) "1"
string(8) "Castelos"
array(3) {
[0]=>
string(80) "buhu"
[1]=>
string(84) "Castelos"
[2]=>
string(83) "Turismo"
}
string(1) "1"
string(1) "0"
string(7) "Turismo"
NULL
So basically the return is not working inside of the condition, wich is exacly what i need =)
