从下拉列表中捕获多个选项

Question

我试图从下拉列表中捕获多个选项并通过邮件发送。 我试过下面的代码。

HTML：

<select name="thelist[]" multiple="multiple">
<option value="Value 1">Value 1</option>
<option value="Value 2">Value 2</option>
</select>

PHP

if( is_array($thelist))
    {
        while (list ($thelist) = each ($thelist)) 
            {
                echo "$thelist <br>";
            }
    }
    else{echo "not working";}

请帮帮我。

Answer 1

$thelist = $_POST['thelist'];
if(is_array($thelist)){
    foreach($thelist as $item){
        echo $item.'<br>';
    }
}else{
    echo 'thelist is not an array';
}

Answer 2

将thelist[]更改为thelist ，因为您命名不同并使用不同的名称，请执行以下操作：

<select name="thelist" multiple="multiple">
<option value="Value 1">Value 1</option>
<option value="Value 2">Value 2</option>
</select>

正如塞缪尔所说：

$thelist = $_POST['thelist'];
if(is_array($thelist)){
  foreach($thelist as $item){
    echo $item.'<br>';
  }
}else{
  echo 'thelist is not an array';
}
