Thanks for the reply cakeFreak, I check out all 3 links and I think I
understand it.
However I cannot seem to get it to save. If I try to add a friend to a
user that has an account in the system it doesn't seem to work, it
yields a warning.
Warning (2): preg_match() [function.preg-match]: Delimiter must not be
alphanumeric or backslash [CORE/cake/libs/model/model.php, line 1674]
It is having problems saving the newly constructed $this->data.
Below is my add_friends function
function addfriend($friend_id = null) {
// $this->data = $this->User->read(array('id'), $this-
>obAuth->getUserId());
//let us try and add friends for the user with
id=3
$this->data = $this->User->read(array('*'), '3');
//view user's info
print_r($this->data['User']);
$friends = array();
foreach ($this->data['Friend'] as $friend) {
$friends[] = $friend['id'];
}
$friends[] = $friend_id;
echo "<br>friend array:";
print_r($friends);
$admirers = array();
foreach ($this->data['Admirer'] as $admirer) {
$admirers[] = $admirer['id'];
}
$admirers[] = $friend_id;
echo "<br>admirer array:";
print_r($admirers);
unset($this->data['Friend']);
unset($this->data['Admirer']);
$this->data['Friend']['Friend'] = $friends;
$this->data['Admirer']['Admirer'] = $admirers;
echo "<br>printing this->data:";
print_r($this->data);
echo "<div> did it save?:
".$this->User->save($this->data)."</
div>";
/* if ($this->User->save($this->data)) {
$this->Session->setFlash('Added to Friends.');
}
*/
}
Also, do I need to populate the friend_id in the users table with
anything? such as the user_id? or just blank. Below is the schema of
my users table.
id
friend_id
group_id
firstname
astname
email
password
active
