旨在将数据输入数据库的 php 脚本正在选择性地工作。5 年级和 10 年级的数据进入，但所有其他年级的数据不会显示。我已经检查了 if else 块，并且逻辑工作正常，它执行内部块，因为它应该不会将任何数据输入数据库。对于 5 年级或 10 年级以外的年级，第二个块被执行，我已经检查过它是否反映了它应该进入数据库的正确值。并在 sql() 查询后使用 echo 我还发现它也可以正常工作，所以有点卡住了，不知道出了什么问题，请帮忙。

这是代码，如果你们也需要html，请告诉我

<?php
$roll=$_POST['roll'];
$marks=$_POST['marks'];
$dbase=$_POST['std'];
$sec=$_POST['sec'];
$sec1=$_POST['sec1'];
$expire= time()+60;
if (empty($roll) || empty($marks) || ($dbase==0))
{

echo '<p align="center">You did not enter all data. Please go back and enter them.</p>';
echo '<FORM><p align="center"><INPUT TYPE="button" VALUE="Go Back" onClick="history.go(-1);return true;"></p></FORM>';
die();
}
else
{
    if($dbase==5)
    {
        $temp="five";
    }
    if($dbase==6)
    {
        $temp="six";
    }
    if($dbase==7)
    {
        $temp="seven";
    }
    if($dbase==8)

表结构（除了“十”表）

列类型 归类属性 Null 默认 ExtraAction id int(11) 否 无 AUTO_INCREMENT
roll varchar(3) latin1_swedish_ci 否 无
标记 smallint(6) 否 无 std varchar(2) latin1_swedish_ci 否 无
sec varchar(1) latin1_swedish_ci 否 无

表十结构

列类型 归类属性 Null 默认 ExtraAction id int(11) 否 无 AUTO_INCREMENT
roll varchar(3) latin1_swedish_ci 否 无
标记 smallint(6) 否 无 std varchar(2) latin1_swedish_ci 否 无

当我像这样修改第二个 if 块时

if(($dbase!=5)&&($dbase!=10))
    {
    $sect=$sec1;
            echo "roll- ";
            echo $roll;
            echo "  marks- ";
            echo $marks;
            echo " std- ";
            echo $dbase;
            echo " section- ";
            echo $sect;
            setcookie("tab", $temp, $expire, "/","skc-hs.com");
    $host="127.0.0.1"; // Host name
    $username="root"; // Mysql username
    $password=""; // Mysql password
    $db_name="data"; // Database name
    $tbl_name=$temp; // Table name
    // Connect to server and select databse.
    mysql_connect("$host", "$username", "$password")or die("cannot connect");
    mysql_select_db("$db_name")or die("cannot select DB");

    // To protect MySQL injection (more detail about MySQL injection)
    $roll = stripslashes($roll);
    $marks = stripslashes($marks);
    $roll = mysql_real_escape_string($roll);
    $marks = mysql_real_escape_string($marks);
    $sql="insert into $tbl_name (roll , marks, std, sec) values ('$roll' , '$marks' , '$dbase' '$sect')";
    mysql_query($sql);
    echo " done";
    die();
    }

当我在 html 表单中输入这些值时，它会回显“滚动 - 12 标记 - 454 std- 7 部分 - B 完成”。我不明白为什么它不会只在数据库中输入这些值

exit()如果使用此代码的任何内容都不是 10 或 5，那么您似乎对脚本：

if(($dbase!=10)&&($dbase!=5)&&($sec1=="0"))
{
    echo '<p align="center">You did not enter all data. Please go back and enter them. 3</p>';
    echo '<FORM><p align="center"><INPUT TYPE="button" VALUE="Go Back" onClick="history.go(-1);return true;"></p></FORM>';
    die();
}

$dbase您忘记在查询和 查询之间放置逗号$sect。

将查询从

   $sql="insert into $tbl_name (roll , marks, std, sec) 
          values ('$roll' , '$marks' , '$dbase' '$sect')";

到

   $sql="insert into $tbl_name (roll , marks, std, sec)
          values ('$roll' , '$marks' , '$dbase' , '$sect')";
