  2. Is adding this code to a contact form to prevent spam OK?

    in PHP

    Posted · Edited by Jono

    What happens when someone has javascript turned off? They see your form, fill it out, hit reply, and get an insulting message. Then, you never email them back. Nice.

    The message still sends with JavaScript turned off (obviously the animations don't work). Insulting message? Why would you think that? It's nice & polite.

     

    There's also a 'If you prefer to use your own email client' link at the bottom of the form. So they can use that if they want to open up an email in their email client & send it that way (or have any trouble).

     

    I want to use the form because in the past people have tended not to send the info I need. With the contact form's required fields more often than not I get the info I need without having to send an email saying 'Can you send this info over?'

    <?php

    function getPostVal($paramName)
    {
    global $_POST;
    return (array_key_exists($paramName, $_POST)) ? Trim(stripslashes($_POST[$paramName])) : '';
    }

    $Name = getPostVal('Name');
    $Company = getPostVal('Company');

    if (!$Name) $missing = "

  5. Is adding this code to a contact form to prevent spam OK?

    in PHP

    Posted

    I saw this tip on another web site to prevent spam on contact forms. In the contact form you add a hidden field

     

     

    And then in the PHP file you add

    if ( $_POST['to_address'] ) { echo 'Tastes Like spam!'; } else {...send email...}

     

    But my PHP file is a little different as also activates some JavaScript on the webpage depending on whether the form is filled out correctly or not (If successful shows a little ?Your email has been sent...? with animation. If the fields aren?t filled out correctly it shows what?s missing).

     

    Someone else made the contact form for me as I don?t know any PHP (or ajax), but I?ve tried to adapt the code above & add it to my PHP form. I?ve tested it & it seems to work OK, but thought I?d just check that it shouldn?t potentially cause any problems, or if it needs tweaking/formatting a little.

    Here?s the last part of my original PHP file

     

    $Body .= "Message: ";
$Body .= $Message;
$Body .= "\n";
$success = true; mail($EmailTo, $Subject, $Body, "From: <$Email>");
}

// call success or error js functions
if ($success){
 print "doThanks()";
}
else{
 print "doError()";
}
?>

     

    And here it is after I added the (hopefully) anti spam code

     

    $Body .= "Message: ";
$Body .= $Message;
$Body .= "\n";
$success = true; mail($EmailTo, $Subject, $Body, "From: <$Email>");
}

// call success or error js functions
if ( $_POST['to_address'] ) { echo 'Tastes Like spam!'; } else

if ($success){
 print "doThanks()";
}

else{
 print "doError()";
}
?>

     

    Does the code I added look OK, or does it need changing in any way? :)

  8. Encode email address, but don?t open email client when clicked on?

    in Javascript

    Posted

    There are quite a few sites that will let you encode your email address via JavaScript to show it on a web site without bots being able to find it, & therefore spam it (or at least it stems the tide).

     

    When you click on them it opens a new email message in the user?s email client with the email address in the ?to? field.

     

    What I want to do is display an email address on a web site & encode it in JavaScript (to help prevent spam), but I don?t want it to open a new email when clicked on (I want to activate some different JavaScript instead).

     

    Does anyone know if this would be possible?
