以 PHP 形式发送复选框值 [英] send checkbox value in PHP form
问题描述
我有一个关于 php 表单的问题.我在现有表单中添加了一个复选框，但不确定如何将其添加到 php.ini 文件中.如果访问者检查它，我希望它发送是"，如果他不检查，则发送否".
I have a question regarding a php form. I've added a checkbox to the existing form, but not sure how to add it to the php. I would like it to send "yes" if the visitores checks it, and "no" if he is not.
<form method="POST" name="contactform" action="contact-form-handler.php">
<p>
<input type="text" name="name" placeholder="name">
</p>
<p>
<input type="tel" name="tel" placeholder="phome"> <br>
</p>
<p>
<input type="text" name="email" placeholder="mail"> <br>
</p>
<p>
<input type="checkbox" name="newsletter[]" value="newsletter" checked>i want to sign up for newsletter<br>
</p>
<input type="submit" value="Submit"><br>
</form>
这里是表单的 php 代码，除了复选框之外的所有内容.当我收到邮件时，我需要知道它的价值.例如:姓名:John，电子邮件:test@test.com，电话:12345，时事通讯:是"
here is the php code for the form, everything there except the checkbox. i need to know its value when i receive the mail. for example : "Name: John, Email: test@test.com, Tel:12345, Newsletter: Yes"
<?php
$errors = '';
$myemail = 'test@gmail.com';//<-----Put Your email address here.
if(empty($_POST['name']) ||
empty($_POST['email']) ||
empty($_POST['tel']))
{
$errors .= "
Error: all fields are required";
}
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];
if (!preg_match(
"/^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$/i",
$email_address))
{
$errors .= "
Error: Invalid email address";
}
if( empty($errors))
{
$to = $myemail;
$email_subject = "Contact form submission: $name";
$email_body = "You have received a new message. ".
" Here are the details:
Name: $name
Email: $email_address
Tel
$message
Newsletter
$newsletter"
}
;
$headers = "From: $myemail
";
$headers .= "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
//redirect to the 'thank you' page
header('Location: contact-form-thank-you.html');
}
?>

推荐答案
这是在检查时返回一个简单的 Yes 的样子.
Here's how it should look like in order to return a simple Yes when it's checked.
<input type="checkbox" id="newsletter" name="newsletter" value="Yes" checked>
<label for="newsletter">i want to sign up for newsletter</label>
我还添加了文本作为标签，这意味着您也可以单击文本来选中该框.虽然很小，但我个人讨厌网站让我将鼠标对准这个小小的复选框.
I also added the text as a label, it means you can click the text as well to check the box. Small but, personally I hate when sites make me aim my mouse at this tiny little check box.
提交表单时，如果选中复选框$_POST['newsletter'] 将等于 Yes.就是如何检查 $_POST['name']、$_POST['email'] 和 $_POST['tel'] 是空的，你也可以这样做.
When the form is submitted if the check box is checked $_POST['newsletter'] will equal Yes. Just how you are checking to see if $_POST['name'],$_POST['email'], and $_POST['tel'] are empty you could do the same.
以下是如何在 php 端将其添加到电子邮件中的示例:
Here is an example of how you would add this into your email on the php side:
在您现有的代码之下:
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];
添加:
$newsletter = $_POST['newsletter'];
if ($newsletter != 'Yes') {
$newsletter = 'No';
}
如果选中该复选框，它将在您的电子邮件中添加Yes，如果未选中，它将添加No.
If the check box is checked it will add Yes in your email if it was not checked it will add No.
