I'm also new to cake and I just accomplished this myself a few days
ago. I only do the start before end validation and not end after
start. I don't know if that's a good way to do it or not. In the
startBeforeEnd validation you specify which field you want to compare
the 'start' field to, in my case it's 'end'. I included a "can't be in
the future" validation in case you might have use for that too.
Here is a portion of my model's code:
var $validate = array(
'start' => array(
'startBeforeEnd' => array(
'rule' => array('startBeforeEnd', 'end' ),
'message' => 'The start time must be before the
end time.'),
'futureDate' => array(
'rule' => array('futureDate', 'start'),
'message' => 'The start time can not be in the
future.'),
),
);
function startBeforeEnd( $field=array(), $compare_field=null ) {
foreach( $field as $key => $value ){
$v1 = $value;
$v2 = $this->data[$this->name][ $compare_field ];
if($v1 > $v2) {
return FALSE;
} else {
continue;
}
}
return TRUE;
}
function futureDate($data, $field){
if (strtotime($data[$field]) > time()){
return FALSE;
}
return TRUE;
}
