我在php上非常糟糕，所以我需要帮助。我创建了一个搜索html表，我想包括每行的编辑和删除按钮。单击编辑按钮后，它将重定向到用户更新数据的编辑页面。我尝试了</form>". if (isset($_POST['edit'])) { $id=$_POST['id']; echo "<script language='javascript'> window.location.href='admin_edit.php?id=$id'</script>";
}."，但语法错误，意外发生，如果＆＃39;下面的代码也无效。
if(isset($_POST['searchq']) && $_POST['searchq'] != "")
{
if(isset($_POST['searchopt']) && $_POST['searchopt'] != "")
{
$escsearch = mysqli_real_escape_string($conn, $_POST['searchq']);
$searchval = preg_replace('#[^a-z 0-9]#i', '', $escsearch);
$opt = $_POST['searchopt'];
switch($opt)
{
case "dpt":
$query = "SELECT * FROM coi_system where department LIKE '%$searchval%'";
$res = mysqli_query($conn, $query) or die(mysqli_error());
$count = mysqli_num_rows($res);
if($count > 0)
