Question

我正在使用此脚本通过PHP表单更新我的MySQL数据库。但由于某种原因，我得到了通知：当我尝试更新时，未经编码的索引......有人能告诉我为什么我会收到错误。

未确定的指数：第75行的融合

$connect_mysql=mysql_connect($server,$username,$password) or die ("Connection Failed!");
$mysql_db=mysql_select_db("helpdesk_middenpolder",$connect_mysql) or die ("Could not Connect to Database");
$query = "SELECT * FROM incidenten";
$result=mysql_query($query) or die("Query Failed : ".mysql_error());
$i=0;
while($rows=mysql_fetch_array($result))
{
$roll[$i]=$rows['incidentID'];
$i++;
}
$total_elmt=count($roll);

Answer 1

Melding: <input name="marks" type="text" /><br />
                      ^^^^^^

您已将输入命名为marks，而不是Melding。

Answer 2

$ _POST中的每个索引都是一个表单字段。你缺少melding字段。

注意：未定义索引，但为什么？
