我有一个包含下拉列表和一些textfiedl的网页，我想要做的是从下拉列表中查看讲师姓名，如下图所示 enter image description here

并存储数据库表中其余表单的数据，其中讲义名称与表名相同。 我的php代码如下

<?php

define('DB_NAME','mydb');
define('DB_USER','root');
define('DB_PASSWORD','');
define('DB_HOST','localhost');

$connect = mysql_connect(DB_HOST,DB_USER,DB_PASSWORD);

if(!$connect){
    die('Could not connect:'.mysql_error());
}

$db_selected=mysql_select_db(DB_NAME,$connect);

if(!$db_selected){
    die('Can\'t use'.DB_NAME.':'.mysql_error());
}
$dim = $_POST['dim'];
$lag = $_POST['lag'];
$stam = $_POST['stam'];
$keh = $_POST['keh'];
$chry = $_POST['chry'];



if(HERE I WANT TO CHECK THAT IF THE LECTURER NAME IS EQUAL TO DIMOPOULOS THEN DO THE BELOW)
{

$value1=$_POST['a1'];
$value2=$_POST['a2'];
$value3=$_POST['a3'];
$value4=$_POST['l1'];

$value12=$_POST['year'];

$sql="INSERT INTO dimopoulos(a1,a2,a3,l1,l2,r1,r2,u1,u2,u3,unit_name,year) VALUES('$value1','$value2','$value3','$value4','$value5','$value6','$value7','$value8','$value9','$value10','$value11','$value12')";

if(!mysql_query($sql)){

我无法做的是为php代码中的每个if找到合适的if语句，以便将数据保存在数据库的正确表中。

2 个答案:

答案 0 :(得分：1)

无需使用IF ELSE您可以简单地编写动态插入语句，这将是一个动态变量，是的，您必须在表单提交期间将相关的TABLE_NAME作为变量从UI传递。

$MY_TABLE=$_POST['TABLE_NAME'];

$sql="INSERT INTO {$MY_TABLE} (a1,a2,a3,l1,l2,r1,r2,u1,u2,u3,unit_name,year) VALUES('$value1','$value2','$value3','$value4','$value5','$value6','$value7','$value8','$value9','$value10','$value11','$value12')";

答案 1 :(得分：-1)

您可以直接通过名称进行检查。

if ($dim == 'dimopoulos') { 
... 
} elseif ($lag == 'lagkas') {
... 
} // same way try for all
