OK, i have an issue, but i dont know, that it works correkt..
it make no sense to get the Last-id in the select.
The concert_id is a parameter in the select query and also the parameter for the last_id
this cannot work.
add_concert.php line 32:
delete the " 'concert_id', " and the " '$concert_id', " in the select query.
The concert_id is auto increment, it will be get a new ID, therefore i dont have to predefine ist.
In the save_concert.php line 53:
If there ist no date defined, it make no sense to compare a non defined Parameter.
(isset($concert_date) AND $concert_date == $fulldate)
Than the parser compare only, if the Parameter $concert_date is set.
This works fine, but i dont know, if this issue works also correct, because i dont know this script very well.
Maybe the Coder will read this an maybe he can repair this in a correct way
