我知道有一个下拉菜单显示我的MYSQL表中的项目。现在它显示了这些不同的名称，但我如何在我的代码中获取所选项目。
所以，如果我打开下拉列表，我得到例如item3，我可以用这个做点什么。 我想要的是，如果选择了项目3 -vs-项目4并且填写form1比填写form2更高（＆gt;）。第3项增加3分，项目4 0分。
希望你能提供帮助。
这是下拉菜单的代码：
<select name="dropdown">
<option value=""></option>
<?php
mysql_data_seek($result, 0);
if(mysql_num_rows($result) > 0){
while($row = mysql_fetch_array($result)) {
echo '<option value="">' . $row['Team'] . '</option>';
}
}
?>
</select>
<input style="width:20px; text-align:center;" type="text" name="hometeam" placeholder="0" />
-
<input style="width:20px; text-align:center;" type="text" name="awayteam" placeholder="0" />
<select name="dropdown">
<option value=""></option>
<?php
mysql_data_seek($result, 0);
if(mysql_num_rows($result) > 0){
while($row = mysql_fetch_array($result)) {
echo '<option value="">' . $row['Team'] . '</option>';
}
}
?>
</select><br>
<select name="dropdown">
<option value=""></option>
<?php
mysql_data_seek($result, 0);
if(mysql_num_rows($result) > 0){
while($row = mysql_fetch_array($result)) {
echo '<option value="">' . $row['Team'] . '</option>';
}
}
?>
</select>
这是我的整个admin.php
<?php
error_reporting(E_ALL ^ E_NOTICE);
if(!isset($_COOKIE['E2ingelogd'])) {
header("location:../../index.php");
}
$username = "root";
$password = "";
$hostname = "localhost";
$dbhandle = mysql_connect($hostname, $username, $password) or die("Kan niet inloggen");
$selected = mysql_select_db("login", $dbhandle);
if(isset($_POST['team'])){
$team = $_POST['team'];
$ID = $_POST['id'];
$query = mysql_query("SELECT * FROM e2teams WHERE Team='$team' and ID='$ID'");
if(mysql_num_rows($query) > 0 ) { //check if there is already an entry for that username
echo "$team bestaat al!";
}
if (!$_POST['team'] )
{
echo('Foutmelding: Je bent vergeten een <b>team</b> in te vullen');
}
else{
mysql_query("INSERT INTO e2teams (Team) VALUES ('$team')");
header("location:e2admin.php");
}
}
mysql_close();

答案 0 :(得分：0)
您需要在value=""的{{1}}部分放置一些内容，这些内容是$ _POST或$ _GET中返回的内容。
您可以在其中放置任何内容，通常是包含['Team']名称的行的ID，但它可以是任何内容，例如：
<option或
if(mysql_num_rows($result) > 0){
while($row = mysql_fetch_array($result)) {
echo '<option value="' . $row['ID'] . '">' . $row['Team'] . '</option>';
}
}
