Error. Appears sometimes when loading a third level menu
structure.
Fatal error: Call to undefined method stdClass::trail() in
/[server/site]/saf/lib/GUI/MenuItem.php on line 138
Cause: This has to do with the build-up of the menu tree in the
SAF, /saf/lib/GUI/menu.php. In here, the sitellite_page table is
loaded, with GROUP BY below_page.
Suppose we have the following (CASE 1).
page_id | below_page
home |
section | home
page | section
This will be loaded in this order and gives no problems.
However, when we rename section to “a_section”, the
order of the results will be this (group by below_page) (CASE
2):
home |
page | a_section
a_section | home
The TREE table, contains fields “parent” and
“children”. When we are in case 2, page will have
parent “a_section”. However, the page a_section is not
loaded at that time, so a StdClass will be loaded instead of a
MenuItem. (function &addItem). This StdClass causes the
errors.
Fix:
In function initTree, change the stdClass to a valid MenuItem.
foreach ($tree as $k => $v) {
if ($v->{$this->listcolumn} == 'no') {
continue;
}
// Start: SEMIAS EDIT. P Hagens. 13 01 2011. Fix error in menu
structure. // if ($v->{$this->refcolumn} && ! isset
($this->{'items_' . $v->{$this->idcolumn}}->parent))
{
if ($v->{$this->refcolumn}) {
$ref = $v->{$this->refcolumn};
$parent = $this->{'items_' . $v->{$this->idcolumn}}->parent;
// When parent is of type StdClass, no id is set.
// Below: fix this and make it type MenuItem
if(!$parent->{$this->idcolumn}) {
// link the parent attr to the parent object
$this->{'items_' . $v->{$this->idcolumn}}->parent =& $this->{'items_' . $ref};
// link the children list to the child object
$this->{'items_' . $ref}->children[] =& $this->{'items_' . $v->{$this->idcolumn}};
}
}
}
