How to send form data to CSV - php

Question

I have a specific request from a client that a newsletter signup be sent to a CSV file. I am a noob when it comes to anything backend, let alone frontend development.
I have a template that I am working from and can't make sense of the way it delivers the values.
The form code is quite simple
<form action="" method="post" class="signup" id="newsletter-form">
<p>
<input type="text" name="signup_name" id="signup_name" class="required" value="Your Name" />
</p>
<p>
<input type="text" name="signup_email" id="signup_email" class="required" value="Your E-mail" />
</p>
<input type="submit" value="SEND" class="signupSubmit" id="submitform" />
<div id="newsletter-msg-wrapper" style="position:relative; clear:both; width:100%;">
<div id="newsletter-loader"></div> <span id="newsletter-msg"> </span>
</div>
</form>
Then I have this .js file that seems to be handling the post
$(document).ready(function () {
var contactFormDefaults = new Array();
contactFormDefaults['name'] = 'Your Name';
contactFormDefaults['email'] = 'E-mail';
contactFormDefaults['subject'] = 'Subject';
contactFormDefaults['message'] = 'Message';
contactFormDefaults['msg'] = $('.contactForm span#msg').html();
$('.contactForm input[type="text"], .contactForm textarea').focus(function () {
$(this).addClass('inputHighlight').removeClass('errorOutline');
if ($(this).hasClass('required')) {
$('.contactForm span#msg').html('This is a required field.').removeClass('errorMsg successMsg');
} else {
$('.contactForm span#msg').html(contactFormDefaults['msg']).removeClass('errorMsg successMsg');
}
if ($(this).val() == contactFormDefaults[$(this).attr('id')]) {
$(this).val('');
}
});
$('.contactForm input[type="text"], .contactForm textarea').blur(function () {
$(this).removeClass('inputHighlight');
$('.contactForm span#msg').html(contactFormDefaults['msg']).removeClass('errorMsg successMsg');
if ($(this).val() == '') {
$(this).val(contactFormDefaults[$(this).attr('id')]);
}
});
$('.contactForm input[type="text"], .contactForm textarea').hover(function () {
$(this).addClass('inputHighlight');
}, function () {
$(this).not(':focus').removeClass('inputHighlight');
});
$('.contactForm').submit(function () {
$('.contactForm .submit').attr("disabled", "disabled");
$('#msg').html('<img src="images/loader-light.gif" />').removeClass('errorMsg successMsg');
var isError = false;
$('.contactForm input, .contactForm textarea').each(function () {
if ($(this).hasClass('required') && ($.trim($(this).val()) == contactFormDefaults[$(this).attr('id')] || $.trim($(this).val()) == '')) {
$(this).addClass('errorOutline');
$('#msg').html('There was an error sending your message. Please try again.').addClass('errorMsg');
isError = true;
}
if ($(this).attr('id') == 'email') {
var reg = /^([A-Za-z0-9_\-\.])+\#([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
if (reg.test($(this).val()) == false) {
$(this).addClass('errorOutline');
if (!isError) {
$('#msg').html('Please enter a valid e-mail address and try again.').addClass('errorMsg');
}
isError = true;
}
}
});
if (isError) {
$('.contactForm .submit').removeAttr("disabled");
return false;
} else {
var name = $('#name').val(),
email = $('#email').val(),
subject = $('#subject').val(),
message = $('#message').val();
$.ajaxSetup({
cache: false
});
var dataString = 'name=' + name + '&email=' + email + '&subject=' + subject + '&message=' + message + '&ajax=1';
$.ajax({
type: "POST",
url: "../myform.php",
data: dataString,
success: function (msg) {
// Check to see if the mail was successfully sent
if (msg == 'Mail sent') {
// Update the progress bar
$('#msg').html('Message sent.').addClass('successMsg');
// Reset the subject field and message textbox
if (contactFormDefaults['subject']) {
$('#subject').val(contactFormDefaults['subject']);
} else {
$('#subject').val('');
}
if (contactFormDefaults['message']) {
$('#message').val(contactFormDefaults['message']);
} else {
$('#message').val('');
}
} else {
$('#msg').html('There was an error sending your email. Please try again.').addClass('errorMsg');
$('.contactForm .submit').attr("disabled", "");
}
// Activate the submit button
$('.contactForm .submit').removeAttr("disabled");
},
error: function (ob, errStr) {
$('#msg').html('There was an error sending your email. Please try again.').addClass('errorMsg');
//Activate the submit button
$('.contactForm .submit').removeAttr("disabled");
}
});
return false;
}
});
});
If possible I'd love to know how to make this all function and what I am not seeing here and how this all can be written into a CSV file.
A full view of the site and code can be viewed here:

The form is at the bottom of the page.

Answer 1

in your myform.php , receive all the data (email, name etc) and start creating your CSV file. It is a simple operation and not that complicated.
For CSV file writing, please check out these posts on stack overflow:

Also do some googling.
Hopefully this will help you.
