Ask for advice. write the message board code for php.

Ask for advice. I have just started to learn php and write code as a message board for php, who can help me see why there are no "reply" or "delete" options on the written page ???



Session_start ();
$ Lydb = new LyDB ();

If (isset ($ _ POST ["type"]) {
If ($ _ POST ["type"] = "insert "){
If (Authority: check_insert () = true ){
$ Lydb-> insert ($ _ POST ["nickname"], "style/avatar /". $ _ POST ["avatar"], $ _ POST ["message"]);
Header ("Location: indexy. php ");
Exit ();
}
}
Else if ($ _ POST ["type"] = "login "){
If (isset ($ _ POST ["username"]) & isset ($ _ POST ["password"]) {
$ Dd = User: validate ($ _ POST ["username"], $ _ POST ["password"]);
If ($ dd = true ){
$ _ SESSION ["username"] =$ _ POST ["username"];
Header ("Location: indexy. php ");
Exit ();
}
Else {

}
}
}
Else if ($ _ POST ["type"] = "reply "){
$ Id = $ _ POST ["id"];
$ Reply = $ _ POST ["reply"];
$ Lydb-> reply ($ id, $ reply );
Header ("Location: indexy. php ");
Exit ();
}
}
Else if (isset ($ _ GET ["type"]) {
If ($ _ GET ["type"] = "delete" & isset ($ _ GET ["id"]) {
If (Authority: check_delete () = true ){
$ Lydb-> delete_by_id ($ _ GET ["id"]);
Header ("Location: indexy. php ");
Exit ();
}
}
Else if ($ _ GET ["type"] = "logout "){
Session_destroy ();
Header ("Location: indexy. php ");
Exit ();
}
}

Header ("Content-Type: text/html; charset = utf-8 ");
?>
