我有一个user class
我在其MYSQL
数据库中创建了一个结果表。我希望在表的每一行都有一个按钮,用户可以单击该按钮删除该行。
public function displayMyBooking() { //Added function
$userid = $this->data()->id; //gets id of user currently logged in
$query = DB::getInstance()->query("SELECT bookingdate, roomid, period FROM booking WHERE id = {$userid}"); //queries database for all bookings made with the id of the current user
$amount = $query->count(); //returns amount of results
$x=0;
//create table
$bookingtable = "<table style='width:100%' class='table'>";
$bookingtable .= "<tr>";
$bookingtable .= "<th>Room ID</th>";
$bookingtable .= "<th>Period</th>";
$bookingtable .= "<th>Booking Date</th>";
$bookingtable .= " </tr>";
for($x=0; $x<$amount; $x++) { //loop through and output data into table according to amount of results returned
$bookingtable .= "<tr>";
$bookingtable .= "<td>" . $query->results()[$x]->roomid. "</td>";
$bookingtable .= "<td>" . $query->results()[$x]->period. "</td>";
$bookingtable .= "<td>" . $query->results()[$x]->bookingdate. "</td>";
$bookingtable .= "<td><input type='submit' name='delete' value='Delete'></td>";
$bookingtable .= "</tr>";
$bookingtable .= "";
}
return $bookingtable;
}
只需
即可在我的页面上访问此功能 <?php
$table = $user->displayMyBooking();
echo $table;
?>
每次预订(我正在开发房间预订系统)都有一个独特的复合主键,我用预订的日期,预订的时间段,用户ID等创建。如何使用我的表格中包含的删除按钮删除该特定的行?

你可以试试这个
<button name="delete_row' value="1234">Delete</button>
或为每一行创建表单,例如
<form action="delete.php">
<input type="hidden" name="row_id" value="1235" />
<td><input type="submit" value="Delete"></td>
<input

我没有在<form>
方法中看到任何displayMyBooking()
被使用,因此在那里使用单独的提交输入元素毫无意义。相反,只需更改此声明
$bookingtable .= "<td><input type='submit' name='delete' value='Delete'></td>";
到此:
$bookingtable .= "<td><a href='delete.php?roomid=" . $query->results()[$x]->roomid . "'>Delete</a></td>";
稍后,在 delete.php 页面上,您可以使用$_GET
超全局访问 特定行/ roomid,如下所示:
if(isset($_GET['roomid']) && (!empty($_GET['roomid']) || $_GET['roomid'] == 0)){
$roomid = $_GET['roomid'];
// perform delete operation
}
