Question

所以我创建了一个简单的注册表单。除了复选框，一切都很完美。它们似乎没有显示在发送给收件人的电子邮件中。

以下是HTML表单部分：

<input type="checkbox" class="radio" name="projectType[]" value="Logo/Identity System" required/>Logo/Identity System<br />
<input type="checkbox" class="radio" name="projectType[]" value="Poster" required/>Poster<br />
<input type="checkbox" class="radio" name="projectType[]" value="Brochure" required/>Brochure<br />

<input type="checkbox" class="radio" name="projectType[]" value="Ad Campaign" required/>Ad Campaign<br />
<input type="checkbox" class="radio" name="projectType[]" value="Website" required/>Website<br />
<input type="checkbox" class="radio" name="projectType[]" value="Other" required />Other<br />

以下是PHP部分：

<?php
$to = 'bolanosjd@gmail.com';
$projectType = $_POST['projectType'];
$body = "Project Type:$projectType\n"
if ($_POST['submit']) {
    if (mail ($to, $body)) {
        echo '<p>You have successfully registered for 2014 Designathon!</p>';
    } else {
        echo '<p>Something went wrong, go back and try again!</p>';
    }
}
?>

按下按钮提交后，所有信息都会被发送，但“项目类型：”为空，没有任何值。如何让它显示所选复选框的值？不要介意课程“收音机”他们以前的单选按钮工作正常，但客户想要多个选择。

Answer 1

您尝试向array发送电子邮件，但need a string。简单地更改您的代码：

$body = "Project Type:$projectType\n"

为：

$types = implode(', ', $projectType);
$body = "Project Type:$types\n";

Answer 2

使用implode()列出复选框值：

<?php
if ($_POST['submit']) {

  $to = 'bolanosjd@gmail.com';
  $projectType = $_POST['projectType'];
  $body = "Project Type: " . implode(", ", $projectType) ."\n";

    if (mail ($to, $body)) {
        echo '<p>You have successfully registered for 2014 Designathon!</p>';
    } else {
        echo '<p>Something went wrong, go back and try again!</p>';
    }
}
?>

Answer 3

foreach($_POST['projectType'] as $value){
  echo $value;
}

Answer 4

您已将项目类型设置为数组（[]）。删除方括号，它应该按预期工作。我原以为“数组”会通过。

<input type="checkbox" class="radio" name="projectType" value="Logo/Identity System" required/>Logo/Identity System

或者，请参阅keaner的示例，它循环遍历所有潜在值（如果可以选择多个值）

复选框值未显示在电子邮件中
