I have run into something similar where I wanted to remove, but first find
out why a Part of the array was even showing up.
I have the 2 debug statements in concession so I can see what data goes in
the save and what is actually saved
Line 225
debug($this->data);
Returns
Array
(
[System] => Array
(
[System] => Array
(
[0] => 3
[1] => 5
[2] => 6
[3] => 1
)
)
)
Line 226
debug($this->User->save($this->data[$model_table], true,
array_keys($this->User->$join_table->schema())));
Returns
Array
(
[User] => Array
(
[id] => 3
)
[System] => Array
(
[0] => 3
[1] => 5
[2] => 6
[3] => 1
[4] => 3
[5] => 5
[6] => 6
[7] => 1
)
)
SQL = UPDATE `users` SET `id` = 3 WHERE `users`.`id` = 3
Howwould I remove the
[User] => Array
(
[id] => 3
)

Subject: Re: Removing an item from a set using Set::Remove.
Wait--that's not right at all! I just looked more closely at what you had
there (it's still early here; 1st coffee). Set::remove() doesn't work like
that. Say you wanted to remove all of the 'name' parts from the input
array. You'd do:
$events = Set::remove($events, '{n}.Event.name');
Giving you something like:
Array
(
[0] => Array
(
[Event] => Array
(
[id] => 1
)
)
[1] => Array
(
[Event] => Array
(
[id] => 2
)
)
[2] => Array
(
[Event] => Array
(
[id] => 3
)
)
)
There's no 3rd param.
For your purposes, why don't you simply use the conditions to keep certain
rows from being selected at all? Either that, or re-think how you're storing
this data. Why do you need to remove this or other rows? Perhaps there's a
more elegant solution.
