Question

my case: after user login ... it will display in table what the book he has ... i added delete link in side each book ... for example i clicked on the link delete in side Math book i want to delete it .. how i can do that please.
i get the books but when i click on delete link nothing happen.
this function display books when user login
public function getBooks($start = 0, $limit = 2)
{
$sql_start = $start * $limit;
$sql_limit = $limit;
//SELECT loginUser.username, Library.nameOfBook FROM loginUser JOIN userBook JOIN Library ON userBook.user_id = loginUser.id AND userBook.book_id = Library.id WHERE loginUser.username="loay";
$query = "SELECT Library.nameOfBook FROM loginUser JOIN userBook JOIN Library ON userBook.user_id = loginUser.id AND userBook.book_id = Library.id WHERE loginUser.username=:username LIMIT $sql_start, $sql_limit";
$statment = $this->db->prepare($query);
$statment->execute([
':username' => $this->username
//,':start' => $start, ':limit' => $limit
]);
$result = $statment->fetchAll();
echo "<table border='1'>
<tr>
<th>Books</th>
<th>Action</th>
</tr>";
foreach($result as $row){
echo "<tr>";
echo "<td>" . $row['nameOfBook'] . "</td>";
echo "<td>" ."<input type='submit' name='delete' value='Delete' method='post' " . "</td>";
echo "</tr>";
}
echo "</table>";
if(isset($_POST['delete'])){
deleteBooks($id1, $id2);
}
}
And this function deleteBooks
public function deleteBooks($id1, $id2)
{
$id1 = $_GET['user_id'];
$id2 = $_GET['book_id'];
$query = "Delete FROM userBook WHERE userBook.user_id=id1 AND userBook.book_id =id2";
$statment = $this->db->prepare($query);
$statment->execute([$id1, $id2]);
$result = $statment->rowCount();
$this->deleteBooks= ($result == "1");
return $this->deleteBooks;
}

First of all you have to add book.id on the link
echo "Delete";
After you click yes you will have a get request.
Not sure where delete function is called after but you can pass $_GET
parameter on it deleteBooks($_GET['id]).
and the function it self
public function deleteBooks($book_id) {
$query = "Delete FROM userBook WHERE userBook.user_id=? AND userBook.book_id =?";
$statment = $this->db->prepare($query);
$statment->bind_param("ss", $user_id, $book_id);
$statment->execute();
//
}
You should store user_id on a session i guess.
