我正在尝试建立一个非常基本的库存管理网站供我个人使用。我在尝试构建'删除'时遇到问题。功能到我的退货项目列表中。
这是来自可见网页的PHP脚本:
<form action='actions.php' method='post'>
<?php
ini_set('display_errors', 1);
//Create Connection
$conn = new mysqli($servername, $username, $password, $dbname);
//Check Connection
if ($conn->connect_error) {
die("Connection Failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM computers WHERE status='Available'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "<table id='unassigned'>
<tr>
<th onclick='sortTable(0)'>Manufacturer</th>
<th onclick='sortTable(1)'>Model</th>
<th onclick='sortTable(2)'>Serial Number</th>
<th onclick='sortTable(3)'>CPU</th>
<th onclick='sortTable(4)'>Memory</th>
<th onclick='sortTable(5)'>HDD</th>
<th onclick='sortTable(6)'>Status</th>
<th onclick='sortTable(7)'>Assignee</th>
<th onclick='sortTable(8)'>Date Assigned</th>
<th onclick='sortTable(9)'>Date Returned</th>
<th>ID - TESTING ONLY</th>
<th>Actions</th>
</tr>";
//output data of each row
while($row = $result->fetch_assoc())
{ $id = $row["sn"];
{
echo "<tr>
<td>".$row["manufacturer"]."</td>
<td>".$row["model"]."</td>
<td>".$row["sn"]."</td>
<td>".$row["CPU"]."</td>
<td>".$row["memory"]."</td>
<td>".$row["hdd"]."</td>
<td>".$row["status"]."</td>
<td>".$row["assignee"]."</td>
<td>".$row["dateout"]."</td>
<td>".$row["datein"]."</td>
<td>" . " <input type='hidden' name = 'id' value= " . $row["sn"] . "> " . "</td>
<td>" . " <input type='submit' name = 'delete' . ' value='Delete' >" . "</td>
</tr>";
}
}
echo "</table>";
}
else {
echo "0 results";
}
$conn->close();
?>
</form>
这就是&action; .php&#39;文件:
<?php
$delete = $_POST["delete"];
$id = $_POST["id"];
ini_set('display_errors', 1);
//Create Connection
$conn = new mysqli($servername, $username, $password, $dbname);
//Check Connection
if ($conn->connect_error) {
die("Connection Failed: " . $conn->connect_error);
}
if (isset($_POST['id'])){
echo "ID is set and it is" . $id;
}
else {
echo "Where is the ID you numpty";
}
if (isset($_POST['delete'])){
$sql = "DELETE FROM computers WHERE sn= $id";
echo "Deleting Stuff";
//if ($conn->query($sql === TRUE) {
//echo "Record deleted successfully";
//}
//else {
//echo "Error deleting record: " . $conn->error;
//}
}
$conn->close();
?>
(请忽略我放入的各种测试内容)
我当然遇到的问题是我已定义:
name = "id"
在我的桌子的每一行上,所以当我按下网页上的任何删除按钮时,在actions.php页面上返回的ID就是最后一行$ [&#39; sn&#39;] ,无论可能是什么......但我想不出为每个ID 和动态分配不同名称的方法,然后在actions.php中抓住它
任何人都可以就如何将SN字段传递到单独文件中的删除查询提供一些指导吗?
谢谢!
