instantiate get form data in a class php - php

Question

I have a simple php form submitting a query into a few classes. The idea of app is to pass in a band name and check a venue to see if that band is playing. If that band is playing it the app will echo out the band and the date that band is playing. I have managed to get the app to work when its all one php file but i am having trouble spitting the single php file into separate classes.
html form :
<form action = "Ass1.php" method = "GET">
<b>Enter band name : </b>
<input type="text" name="bandName" />
<input name="submit" type="submit" value="Click" />
</form>
The entire php file that works:
<?php
class Concert {
public $Artist = '';
public $Date = '';
function SetConcert( $NewArtist = '', $NewDate = '' ) {
$this->Artist = $NewArtist;
$this->Date = $NewDate;
}
function GetArtist() {
return $this->Artist;
}
function GetDate() {
return $this->Date;
}
}
class Venue {
public $VenueName = '';
public $ConcertsInVenue = array();
function SetVenueName( $NewVenue = '' ) {
$this->VenueName = $NewVenue;
}
function GetVenueName() {
return $this->VenueName;
}
function AddConcert( $NewArtist = '', $NewDate = '' ) {
$NewConcert = new Concert;
$NewConcert->SetConcert( $NewArtist, $NewDate );
$this->ConcertsInVenue[] = $NewConcert;
}
function ListConcertsInVenue( $SearchQuery = '' ) {
//Assume Results Will Be Filtered
$ListAllConcerts = FALSE;
//If Search Query Is Blank, List All Concerts
if( $SearchQuery == '' ){
$ListAllConcerts = TRUE;
}
echo 'Concerts In '.$this->VenueName.':';
//Loop Through All Concerts In This Venue
foreach( $this->ConcertsInVenue as $tmpConcert ){
if( $SearchQuery == $tmpConcert->GetArtist() || $ListAllConcerts == TRUE ){
echo '<p>';
echo $tmpConcert->GetArtist().', ';
echo $tmpConcert->GetDate();
echo '</p>';
}
}
}
}
//Create New Venue Object
$tmpVenue = new Venue;
//Set Venue Name
$tmpVenue->SetVenueName( 'Wembley' );
//Add Concerts To Venue
$tmpVenue->AddConcert( 'Rollin\' Empire', '05-02-2018' );
$tmpVenue->AddConcert( 'Metallica', '06-02-2018' );
$tmpVenue->AddConcert( 'Led Zeppelin', '07-02-2018' );
$tmpVenue->AddConcert( 'Rollin\' Empire', '19-02-2018' );
//Search For Artist In Venue ( Leave Blank To List All )
$tmpVenue->ListConcertsInVenue($_GET['bandName']);
?>
Ive tries creating 3 classes Venue.class.php Concert.class.php and app.class.php and its not working
concert.class.php
<?php
include ("Venue.class.php");
class Concert {
public $Artist = '';
public $Date = '';
function SetConcert( $NewArtist = '', $NewDate = '' ) {
$this->Artist = $NewArtist;
$this->Date = $NewDate;
}
function GetArtist() {
return $this->Artist;
}
function GetDate() {
return $this->Date;
}
}
?>
Venue.class.php
<?php
include ("Concert.class.php");
class Venue {
public $VenueName = '';
public $ConcertsInVenue = array();
function SetVenueName( $NewVenue = '' ) {
$this->VenueName = $NewVenue;
}
function GetVenueName() {
return $this->VenueName;
}
function AddConcert( $NewArtist = '', $NewDate = '' ) {
$NewConcert = new Concert;
$NewConcert->SetConcert( $NewArtist, $NewDate );
$this->ConcertsInVenue[] = $NewConcert;
}
function ListConcertsInVenue( $SearchQuery = '' ) {
//Assume Results Will Be Filtered
$ListAllConcerts = FALSE;
//If Search Query Is Blank, List All Concerts
if( $SearchQuery == '' ){
$ListAllConcerts = TRUE;
}
echo 'Concerts In '.$this->VenueName.':';
//Loop Through All Concerts In This Venue
foreach( $this->ConcertsInVenue as $tmpConcert ){
if( $SearchQuery == $tmpConcert->GetArtist() || $ListAllConcerts == TRUE ){
echo '<p>';
echo $tmpConcert->GetArtist().', ';
echo $tmpConcert->GetDate();
echo '</p>';
}
}
}
}
?>
app.php
<?php
include ("Venue.class.php");
include ("Concert.class.php");
//Create New Venue Object
$tmpVenue = new Venue;
//Set Venue Name
$tmpVenue->SetVenueName( 'Wembley' );
//Add Concerts To Venue
$tmpVenue->AddConcert( 'Rollin\' Empire', '05-02-2018' );
$tmpVenue->AddConcert( 'Metallica', '06-02-2018' );
$tmpVenue->AddConcert( 'Led Zeppelin', '07-02-2018' );
$tmpVenue->AddConcert( 'Rollin\' Empire', '19-02-2018' );
//Search For Artist In Venue ( Leave Blank To List All )
$tmpVenue->ListConcertsInVenue($_GET['bandName']);
?>
Would I need to create a new class in app.php to handle the form input and pass it to the other classes?
