我正在尝试更新属性的值
$lid = $_GET["id"];
$check_user = mysql_query("select employee.Emp_Name, leave.Leave_Type from `leave`, employee where leave.Leave_ID = $lid AND leave.Emp_ID = employee.Emp_ID ");
while($rows = mysql_fetch_assoc($check_user))
{
echo "<td>: </td>";
echo "<td>". $rows['Leave_Type']."</td>";
echo "</tr>";
echo "<td>: </td>";
echo "<td>". $rows['Emp_Name']."</td>";
echo "</tr>";
}
if (isset($_POST["submitbtn"]))
{
if($rows['Leave_Type'] == 'Annual')
{
mysql_query("update `leave` set Status = 'Approved' where Leave_ID = $lid");
}
}
当我运行它时没有错误,但我的数据库中的属性值没有更新
答案 0 :(得分:0)
转义变量以避免SQL注入
$lid = $_GET["id"];
$check_user = mysql_query("select employee.Emp_Name, leave.Leave_Type from `leave`, employee where leave.Leave_ID = '" . $lid . "' AND leave.Emp_ID = employee.Emp_ID ");
据我所知你选择的东西如果等于ID,那么你的ID可能是唯一的,你不需要while循环,如果你需要抱歉:)
$rows = mysql_fetch_assoc($check_user));
echo "<td>: </td>";
echo "<td>". $rows['Leave_Type']."</td>";
echo "</tr>";
echo "<td>: </td>";
echo "<td>". $rows['Emp_Name']."</td>";
echo "</tr>";
现在,如果您想要发布帖子,我希望,您在某个地方有一个表单,然后您进行了更新
if (isset($_POST["submitbtn"]))
{
$Leave_Type = $_POST['Leave_Type'];
if($Leave_Type == 'Annual')
{
mysql_query("update `leave` set Status = 'Approved' where Leave_ID = '" . $lid . "'");
}
}
