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。我已经添加一个复选框到现有的表单，但不知道如何将其添加到PHP。

 < form method =POSTname =contactformaction =contact-form-handler.php> 
< p> 
< input type =textname =nameplaceholder =name> 
< / p> 
< p> 
< input type =telname =telplaceholder =phome> < br> 
< / p> 
< p> 
< input type =textname =emailplaceholder =mail> < br> 
< / p> 
< p> 
< input type =checkboxname =newsletter []value =newsletterchecked>我想注册电子报< br> 
< / p> 
< input type =submitvalue =Submit>< br> 
< / form> 
  

这里是表单的PHP代码，除了复选框以外的所有东西。我需要知道它的价值，当我收到邮件。例如：Name：John，Email：[e-mail]，Tel：12345，Newsletter：Yes

  ？php 
 $ errors =''; 
 $ myemail ='[e-mail]'; //< -----把你的电子邮件地址放在这里。 
 if（empty（$ _ POST ['name']）|| 
 empty（$ _ POST ['email']）|| 
 empty（$ _ POST ['tel']））
 {
 $ errors。=\\\
错误：所有字段都是必填的; 
} 
 
 $ 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  - ] +）*（\。[az] {2,3}）$ / i，
 $ email_address））
 {
 $ errors。=\\\
错误：电子邮件地址无效; 
} 
 
 if（empty（$ errors））
 {
 $ to = $ myemail; 
 $ email_subject =联系表单提交：$ name; 
 $ email_body =您收到了一条新消息。。 
详细信息：\\\
名称：$ name \\\
电子邮件：$ email_address \\\
电话\\\
 $ message\\\
通讯\\\
 $ newsletter
} 
; 
 
 
 $ headers =From：$ myemail\\\
; 
 $ headers。=回复：$ email_address; 
 
 mail（$ to，$ email_subject，$ email_body，$ headers）; 
 //重定向到谢谢页面
 header（'Location：contact-form-thank-you.html'）; 
} 
？> 
<！DOCTYPE HTML PUBLIC -  // W3C // DTD HTML 4.01 Transitional // ENhttp://www.w3.org/TR/html4/loose.dtd\">

<？php 
 echo nl2br（$ errors）;

< / body> ;, 
< / html> 
  

谢谢，

解决方案

$ p

pre> < input type =checkboxid =newslettername =newslettervalue =Yeschecked>
< label for =newsletter>我想注册电子报< / label>


我还添加了文本作为标签，这意味着您可以单击文本以检查框。

如果复选框被选中，表单提交时 $ _ POST ['newsletter'] 将等于是。你如何检查 $ _ POST ['name'] ， $ _ POST ['email'] 和 $ _ POST ['tel'] 都是空的，你可以这样做。

您可以将其添加到您的php端的电子邮件中：

在您现有的代码下：

  $ name = $ _POST ['name']; 
 $ email_address = $ _POST ['email']; 
 $ message = $ _POST ['tel']; 
  

添加：

 code> $ newsletter = $ _POST ['newsletter']; 
 if（$ newsletter！='Yes'）{
 $ newsletter ='No'; 
} 
  

如果选中此复选框，则会添加 Yes 在您的电子邮件中，如果未选中它将添加否。

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>

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: [e-mail], Tel:12345, Newsletter: Yes"

<?php 
$errors = '';
$myemail = '[e-mail]';//<-----Put Your email address here.
if(empty($_POST['name'])  || 
   empty($_POST['email']) || 
   empty($_POST['tel']))
{
    $errors .= "\n 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 .= "\n 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:\n Name: $name \n Email: $email_address \n Tel \n $message\n Newsletter \n $newsletter"
}
    ; 


    $headers = "From: $myemail\n"; 
    $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');
} 
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html>
<head>
    <title>Contact form handler</title>
</head>

<body>
<!-- This page is displayed only if there is some error -->
<?php
echo nl2br($errors);
?>


</body>
</html>

Thank you,

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>

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.

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.

Here is an example of how you would add this into your email on the php side:

Underneath your existing code:

$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];

Add:

$newsletter = $_POST['newsletter'];
if ($newsletter != 'Yes') {
    $newsletter = 'No';
}

If the check box is checked it will add Yes in your email if it was not checked it will add No.
