PHP电子邮件未通过if语句发送

Question

I am trying to use php to mail an email to a user if they check off a checkbox. The email doesn't get sent. Can you use the ($_POST["receive-access"]) === checked ?

HTML:

<tr><td><p style="font-family:latine;">Email: </td><td><input type="email" name="mail" id="mail" style="font-family:latine;" required></p></td>
<br>
</tr>
<tr><td><input type="checkbox" id="receive-access" name="receive-access"></td>
<td><label for="receive-access">Check off this box for access to restricted areas.</label></td></tr>

PHP:

<?php
    $message = "Username: username Password: password";
    $recipient = $_POST["mail"];
    if(isset($_POST["receive-access"]) === checked)
    mail($recipient, "Restricted access username and password", $message);
?>

Answer 1

Your messing up 2 kinds of if statements. What your looking for is this:

if(isset($_POST["receive-access"]) && $_POST["receive-access"] === checked)

The first statement isset will return true if the value is set. And then you have to check if the value equals to checked

But then again, if your POST value isset, the checkbox is checked. So the second part of the check isn't needed at all (probably won't work even)

So all you have to do is this:

if(isset($_POST["receive-access"]))

If you need more information about checkboxes and PHP, you could take a look at this website

由于复选框“ retrieve-access”仅在选中时才发送，您可以这样做。

if(isset($_POST["receive-access"]))

Answer 3

Here's how you do it hence checkbox won't exist in post if it is unchecked. Enjoy!

if(isset($_POST['receive-access']) && $_POST['receive-access'] == 'on')
{
   $_POST['receive-access'] = true;
}
else
{
   $_POST['receive-access'] = false;
}

$message = "Username: username Password: password";
$recipient = $_POST["mail"];
if(isset($_POST["receive-access"]) == true)
mail($recipient, "Restricted access username and password", $message);
