Calling two methods from table wrapper in a class - php

Question

I want to create a table which generates data from the database and I need to have update and delete function for each row of data in the table. But i failed to do both update and delete because i put both function in one controller
This is my view file which include the controller to show the data.
<table class="table table-hover">
<tr class="table-active">
<td>Booth ID</td>
<td>Booth Location</td>
<td>Participant ID </td>
<td></td>
<td></td>
</tr>
<tr>
<?php include 'BoothViewController.php'; ?>
</tr>
</table>
This is my controller to display the data in rows. Each row will have update and delete function. The update function will bring the user to another page while delete function is merely remove that row of data.
<?php
require 'boothmodel.php';
$result = viewbooth();
if($result){
while($array = mysqli_fetch_array($result)){
echo "<td>".$array["BoothID"]."</td>";
echo "<td>".$array["Boothlocation"]."</td>";
echo "<td>".$array["ParticipantID"]."</td>";
echo "<td><a href='BoothFormUpdate.php?bid=".$array['BoothID'].
"&blocation=".$array['Boothlocation']."&pid=".$array['ParticipantID']."'>Update</a></td>";
echo "<td><a href='BoothViewController.php?bid=".$array['BoothID'].
"&blocation=".$array['Boothlocation']."&pid=".$array['ParticipantID']."'>Delete</a></td>";
}
return;
}
if(isset($_GET['bid'])){
$selectedbid = $_GET['bid'];
$result = deletebooth($selectedbid);
if($result){
echo "<script language = 'javascript'>";
echo "alert('Booth deleted!');";
echo "window.location.href = 'BoothView.php';";
echo "</script>";
}
}?>
this is my model.
<?php
require 'connection.php';
mysqli_select_db($conn, "ims");
function viewbooth(){
global $conn;
$query = "SELECT * FROM booth";
$result = mysqli_query($conn, $query);
return $result;
}
function updatebooth($bid, $newbloc){
global $conn;
$update = "UPDATE booth
SET Boothlocation='".$newbloc.
"'WHERE BoothID='".$bid."'";
$result = mysqli_query($conn, $update);
return $result;
}
function deletebooth($selectedbid){
global $conn;
$delete = "DELETE FROM booth WHERE BoothID=".$selectedbid;
$result = mysqli_query($conn, $delete);
return $result;
}?>
I know i can simply do the delete function in another controller but im trying to put all in one controller.

You need to create a basic routing mechanism, e.g.
if(isset($_GET['bid'], $_GET['action']))
{
$selectedbid = $_GET['bid'];
$action = $_GET['action'];
switch ($action)
{
case 'delete':
$result = deletebooth($selectedbid);
if($result){
echo "<script language = 'javascript'>";
echo "alert('Booth deleted!');";
echo "window.location.href = 'BoothView.php';";
echo "</script>";
}
break;
case 'update':
// do the updating
break;
}
}
then you can add update and delete links to your items:
Update item
Delete item
Your code hardly resembles the MVC pattern and has many issues. However, the routing idea should work.
