組合兩個單獨的數組

Question

我有兩個單獨的數組，我的PHP郵件格式是不同的複選框組：網絡細節和graphicdetails。只有一組將被填寫（另一個將被隱藏，除非選擇了前一個單選按鈕。）我想​​知道如何在PHP中正確引用它們。

這是我用來獲取一個發佈，但不是兩個：

foreach($_POST['webdetails'] as $value1) { 
    $webdetails_msg .= "$value1\n"; 
} 

我怎麼在裏面添加graphicdetails？複製的片段讓我警告：（）提供的foreach無效參數

我不知道遠不止此PHP，這樣的解釋，將不勝感激。

這裏的PHP我得到一個錯誤有：

<?php 
/* Set mail headers */ 
$myemail = "my.email@gmail.com"; 
$subject = "New Request"; 

$webdetails   = $_POST['webdetails']; 
$graphicdetails  = $_POST['graphicdetails']; 

foreach($_POST['webdetails'] as $value1) { 
    $webdetails_msg .= "$value1\n"; 
} 
foreach($_POST['graphicdetails'] as $value2) { 
    $graphicdetails_msg .= "$value2\n"; 
} 

/* Let's prepare the message for the e-mail */ 
$message = " 
Details: 
$webdetails_msg 
$graphicdetails_msg 
"; 

/* Send the message using mail() function */ 
mail($myemail, $subject, $message); 

<?php exit(); } ?> 

HTML爲webdetails：

<input type="checkbox" name="webdetails[ ]" id="design" value="Design" /> 
<input type="checkbox" name="webdetails[ ]" id="development" value="Development" /> 
<input type="checkbox" name="webdetails[ ]" id="web-updates" value="Web Updates" /> 
<input type="checkbox" name="webdetails[ ]" id="forum-template" value="Forum Template (Full)" /> 
<input type="checkbox" name="webdetails[ ]" id="forum-graphics" value="Forum Graphics" /> 
<input type="checkbox" name="webdetails[ ]" id="web-other" value="Other" /> 

HTML爲graphicdetails：

<input type="checkbox" name="graphicdetails[ ]" id="graphic-logo" value="Logo Design" /> 
<input type="checkbox" name="graphicdetails[ ]" id="graphic-social" value="Social Media Graphics" /> 
<input type="checkbox" name="graphicdetails[ ]" id="graphic-other" value="Other" /> 

Answer 1

它看起來很好，所以我猜測NG那就是：

複選框沒有得到公佈，如果不檢查他們，你需要檢查有任何

if (isset($_POST['graphicdetails'])){ 
    foreach($_POST['graphicdetails'] as $value1) { 
     $webdetails_msg .= "$value1\n"; 
    } 
} 

但在任何情況下

if (isset($_POST['graphicdetails'])){ 
    $webdetails_msg .= implode("\n", $_POST['graphicdetails'])."\n"; 
} // you don't need the curly braces for 1 line but SO has a small code width
