PHP mailer form with radio buttons using AJAX to send

Question

TL; DR Solution: change .val in the javascript to .serialize for any radio inputs.

I've been using this tutorial to build a form that, when the submit button is pressed, fades out the button and fades in a "thanks" message and sends the mailer.php in the background. My form has radio buttons and I cannot seem to figure out how to get the javascript to send which button was selected through to my email.

Here's the form html:

<form action="" method="" name="rsvp" id="rsvp-form">
<fieldset>
                <legend>RSVP</legend>

                    <ol>
                        <li>
                            <input id="accepts1" class="rsvps" name="rsvps" type="radio" value="Graciously_Accepts" />
                            <label for="accepts1">Graciously Accepts</label>
                        </li>
                        <li>
                            <input id="declines1" class="rsvps" name="rsvps" type="radio" value="Regretfully_Declines" />
                            <label for="declines1">Regretfully Declines</label>
                        </li>
                        <li>
                            <input id="accepts2" class="rsvps" name="rsvps" type="radio" value="Regretfully_Accepts" />
                            <label for="accepts2">Regretfully Accepts</label>
                        </li>
                        <li>
                            <input id="declines2" class="rsvps" name="rsvps" type="radio" value="Graciously_Declines" />
                            <label for="declines2">Graciously Declines</label>
                        </li>
                    </ol>
            </fieldset>
<div id="rsvp-wrapper">
    <fieldset>
     <button class="button" type="submit" value="send">RSVP!</button>
</fieldset>

</form>
<div class="success"></div>
</div>

The javascript:

<script type="text/javascript">

$(function() {  

$(".button").click(function() {  

var rsvps = $(".rsvps").val();

var dataString = 'rsvps=' + rsvps;  

    $.ajax({  
      type: "POST",  
      url: "rsvp-mailer.php",  
      data: dataString,  
      success: function() {  
        $('#rsvp-wrapper').html("<div class='success'></div>");  
        $('.success').html("<p class='italic'>Thanks!</p>")   
        .hide()  
        .fadeIn(500, function() {  
          $('.success');  
        });  
      }  
    });  
    return false;   
});  
});  

</script>

And the mailer.php:

<?php 

$rsvps = $_POST['rsvps'];

$formcontent="

RSVP: $rsvps \n";

$recipient = "myemail@domain.com";

$subject = "RSVP";

$mailheader = "RSVP \r\n";

mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");

?>

Thank you so much for any insight you can provide.

Give this a try. See jQuery.post() for more info.

<script type="text/javascript">
    $('form').submit(function() {
        var data = $(this).serialize();

        $.post("rsvp-mailer.php", data, function() {
            $('#rsvp-wrapper').html("<div class='success'></div>");  
            $('.success').html("<p class='italic'>Thanks!</p>")   
            .hide()  
            .fadeIn(500, function() {  
                $('.success');  
            });  
        }

    return false;
    }
</script>

Answer 2

而不是通过类选择器访问单选按钮，请尝试以下操作：

var rsvps = $('input[name=rsvps]:radio').val();

Answer 3

You don't need javascript to get the values in order for them to be sent to the email. Use PHP instead.

   $formcontent .= $_POST['rsvp'];

That line will added before $recipient should send the value of the radio buttons.

Answer 4

change var rsvps = $(".rsvps").val(); to var rsvps = $(".rsvps[selected=selected]").val();

Also, dataString needs to be a json object like this var dataString = { rsvps : rsvps }; to be accessible via ajax POST.
