我试图获取它，以便当行“状态”显示“已完成”或“进行中”时，记录不允许用户更新。不知道如何实现这一点。基本上，只有当行状态 = 已接收时，他们才能单击链接到 update_id.php 的 id。如果已完成或正在进行中，他们会弹出一个框，显示自定义错误消息。我正在寻找示例或教程。
<?php
require_once 'db_connect.php';
$conn = dbConnect();
$OK = true; // We use this to verify the status of the update.
if (isset($_GET['id'])) {
// Create the query
$data = "%".$_GET['id']."%";
$sql = 'SELECT * FROM requests WHERE id like ?';
$stmt = $conn->prepare($sql);
$results = $stmt->execute(array($data));
$rows = $stmt->fetchAll();
$error = $stmt->errorInfo();
//echo $error[2];
}
// If there are no records.
if(empty($rows)) {
echo "<tr>";
echo "<td colspan='4'>There were not records</td>";
echo "</tr>";
}
else {
foreach ($rows as $row) {
echo "<tr>";
$id = $row['id'];
echo "<td><a href='update_Id.php?id=$id'>$id</a></td>";
echo "<td>".$row['name']."</td>";
echo "<td>".$row['lanId']."</td>";
echo "<td>".$row['department']."</td>";
echo "<td>".$row['mgrname']."</td>";
echo "<td>".$row['work_requested']."</td>";
echo "<td>".$row['purchase_order']."</td>";
echo "<td>".$row['inbound_shipment']."</td>";
echo "<td>".$row['status']."</td>";
echo "<td>".$row['request_comments']."</td>";
echo "</tr>";
}
}
?>

最佳答案
如果单词“completed”或“In_progress”被发回更新页面的文本框中，我可以创建一个 JavaScript 来禁用该按钮。它还会提醒用户，如果状态文本框未显示“已收到”，他们将无法更新。
这是经过修改的更新页面，供其他人查看其完成情况。
<?php
include('../db_connect.php');
include('../functions/functions.php');
$id=$_GET['id'];
$result = $db->prepare("SELECT * FROM requests WHERE id= :id");
$result->bindParam(':id', $id);
$result->execute();
for($i=0; $row = $result->fetch(); $i++){
