從下拉列表中捕獲多個選項

Question

我試圖從下拉列表中捕獲多個選項並通過郵件發送它。 我試過下面的代碼。

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";} 

請幫助我。

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

變化thelist[]到thelist，因爲你的命名不同，有不同的名稱醒目，這樣做：

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

和塞繆爾說：

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