郵件格式的複選框

Question

我試圖創建一個電子郵件表單，其中一個人寫他們的電子郵件，評論和選擇他們想要的特定服務。他們可以選擇不同的選項。但問題是，我得到這個錯誤：

Warning: implode(): Invalid arguments passed in C:\xampp\htdocs\html_form_send.php on line 43 

order.php

<form name="htmlform" method="post" style="margin: 0; padding: 0;" action="html_form_send.php"> 
    <table width="900px">

    <tr> 
    <td valign="top"> 
     <label for="email" style="font-weight: bold">Email Address *</label>

    <td valign="top">

html_form_send.php：

<?php 
    error_reporting(-1); 
    ini_set('display_errors', 'On'); 
    if(isset($_POST['email'])) { 

    // EDIT THE 2 LINES BELOW AS REQUIRED 
    $email_to = "email@gmail.com"; 
    $email_subject = "Design Offer"; 
    $email_from = "from@from.com"; 

    $email_message = "Form details below.\n\n"; 

    function clean_string($string) { 
    $bad = array("content-type","bcc:","to:","cc:","href"); 
    return str_replace($bad,"",$string); 
    } 

    $email_message .= "Email: ".clean_string($_POST["email"])."\n"; 
    $email_message .= "Design type: ".implode(",", $_POST['design'])."\n"; 
    $email_message .= "Comments: ".clean_string($_POST["comments"])."\n"; 


    // create email headers 
    $headers = 'From: '.$email_from."\r\n". 
    'Reply-To: '.$email_from."\r\n" . 
    'X-Mailer: PHP/' . phpversion(); 
    mail($email_to, $email_subject, $email_message, $headers); 
    ?>

我得提醒你，我不是很熟悉PHP：/

Answer 1

試試這個：

<input type="checkbox" name="design[]" value="twitch_design" /> Twitch Design <font size="1"><i>(Includes offline background, buttons or headers, wallpaper, cam overlay)</i><br /></font> 
    <input type="checkbox" name="design[]" value="wallpaper" /> Wallpaper <br /> 
    <input type="checkbox" name="design[]" value="webdesign" /> Web Design <font size="1"><i>(A full web design with code)</i><br /></font> 
    <input type="checkbox" name="design[]" value="logo" /> Logo <br /> 
    <input type="checkbox" name="design[]" value="logo" /> Other <font size="1"><i>(Write in comment)</i><br /></font> 

Answer 2

而不是調用你的表單元素design[1]，design[2]等，儘量只給它們命名所有design[]，就像這樣：

<td valign="top"> 
    <input type="checkbox" name="design[]" value="twitch_design" /> Twitch Design <font size="1"><i>(Includes offline background, buttons or headers, wallpaper, cam overlay)</i><br /></font> 
    <input type="checkbox" name="design[]" value="wallpaper" /> Wallpaper <br /> 
    <input type="checkbox" name="design[]" value="webdesign" /> Web Design <font size="1"><i>(A full web design with code)</i><br /></font> 
    <input type="checkbox" name="design[]" value="logo" /> Logo <br /> 
    <input type="checkbox" name="design[]" value="logo" /> Other <font size="1"><i>(Write in comment)</i><br /></font> 
</td> 

PHP會自動將它們連接到的順序數組，他們都被列入這一頁。
