Not sending via email | 易学教程

问题

I'm trying to create a simple email form for a client and cannot get the <textarea> to send as a message. I've tried everything I have found so far and nothing is working properly...
Here is my code:

<h4>Email Al</h4>
<table>
<form name="contactForm" id="contact" action="send_form_email.php" method="post">
    <tr>
    <td>
    <label>Name:</label>
    <input type="text" name="name">
    </td>
    <td>
    <label>Email Address:</label>
    <input type="email" name="email">
    </td>
    </tr>
    <tr>
    <td colspan="2">
    <label>Website (if Available):</label>
    <input type="text" name="website">
    </td>
    </tr>
    <tr>
    <td colspan="2">
    <label>Your Message:</label></br>
    <textarea for="" name="information" width="100%" rows="10" form="contactForm"></textarea>
    </td>
    </tr>
    <tr>
    <td colspan="2">
    <input type="submit" value="Send Message">
    </td>
    </tr>
</form>
</table>

That is the form in the index.php file, below is the email send-email.php

<?php
  $name = $_POST['name'];
  $email = $_POST['email'];
  $website = $_POST['website'];
  $message = $_POST['information'];

    $email_from = 'myemail@gmail.com';

    $email_subject = $name . " has sent you a message!";

    $email_body = "You have received a new message from " . $name . " via your website!\n".
                            "Name:\n $name\n".
                            "Email:\n $email\n".
                            "Website:\n $website\n".
                            "Message:\n $message\n".



  $to = "clientemail@gmail.com";

  $headers = "From: $email_from \r\n";

  $headers .= "Reply-To: $visitor_email \r\n";

  mail($to,$email_subject,$email_body,$headers);


function IsInjected($str)
{
    $injections = array('(\n+)',
           '(\r+)',
           '(\t+)',
           '(%0A+)',
           '(%0D+)',
           '(%08+)',
           '(%09+)'
           );

    $inject = join('|', $injections);
    $inject = "/$inject/i";

    if(preg_match($inject,$str))
    {
      return true;
    }
    else
    {
      return false;
    }
}

if(IsInjected($visitor_email))
{
    echo "Bad email value!";
    exit;
}
?>
<?php
header("Location: /formsubmitted.php"); /* Redirect browser */
exit();
?>

If anyone has any clue why this is malfunctioning I would love to know as well! This is one of the first message/email php functions I've created myself as I usually develop for wordpress, so I would normally just install a plugin for my client.

That's because of this line: (Consult my footnote)

"Message:\n $message\n".

You have a dot instead of a (closing) semi-colon ;

Edit: You need to remove form="contactForm" from <textarea>. Upon testing, it did not show in mail when used with it.

and error reporting would have told you about it.

http://php.net/manual/en/function.error-reporting.php

Being:

Notice: Undefined index: information (line 8)

and

Notice: Undefined variable: visitor_email (line 26 and 55)

In both:

$headers .= "Reply-To: $visitor_email \r\n";

and

if(IsInjected($visitor_email))

$visitor_email is undefined in your code. You should have used $email instead for all instances of $visitor_email.

Then you have for="" which doesn't appear to be valid syntax in your <textarea...

That for="" is ambiguous.

Ref: https://developer.mozilla.org/en/docs/Web/HTML/Element/textarea

You should also check for empty fields with a conditional !empty().

http://php.net/manual/en/function.empty.php

Footnote:

After more intensive testing, and in regards to the dot that I mentioned above, I must state the following:

Strangely enough, PHP sees it as being valid syntax, as there is a semi-colon in and included at the end here $to = "clientemail@gmail.com";

What that will do is still send mail, BUT also include that in the email, which is clearly not included in the $email_body variable body.

Therefore, the first part of my answer was right to a certain extent, the form="contactForm" being the major culprit here.

You may have meant to use an ID id="contactForm" or a class class="contactForm". Both are valid to be used and will include it in your mail.

However, you won't be able to use name="contactForm" since your <form> holds that named attribute.

Both the name and id attributes are (meant to be) unique.

回答2:

Remove form="contactForm" from <textarea>. I removed it. And, it started working.

Replace

<textarea for="" name="information" width="100%" rows="10" form="contactForm"></textarea>

<textarea for="" name="information" width="100%" rows="10"></textarea>

Or,

According to HTML5, You can use, form id's in input. So, in place of form="contactForm" use form="contact".

Change

<textarea for="" name="information" width="100%" rows="10" form="contactForm"></textarea>

<textarea for="" name="information" width="100%" rows="10" form="contact"></textarea>

For more info, check textarea - attributes
