I have the following forms that are rendered by some PHP logic. The forms render fine; you can see the text inputs and submit button and all.
In IE the forms work as expected. The first form goes to 'index.php?subscribe=go' and the second to 'index.php?unsub=go', but in FF and Chrome, clicking the submit button reloads the page (does not go to form action). I have not checked other browsers.
I found in Firebug that the <form> tag doesn't even exist on the page in Firefox. This is very strange; check it out:
else
{
echo '<div class="subs_main">';
if (isset($_GET['subscribe']))
{
if ($_GET['subscribe'] != 'go')
{?>
Subscribe to <b>Bella Blog</b> for specials, sales, news and more!
<br />
<form action="index.php?subscribe=go" method="post" name="subscribe_form" onsubmit="return checkForm();">
Name: <input type="text" name="name" size="15" />
<br />
Email: <input type="email" name="email" size="20" />
<br />
<input type="submit" value="subscribe!" name="submit" />
</form>
<p class="unsub">You can <a href="index.php?unsub">unsubscribe</a> at any time</p>
<?php
}
else
{
// subscribe user
}
}
elseif (isset($_GET['unsub']))
{
if ($_GET['unsub'] != 'go')
{?>
Sorry to see you go! You can <a href="index.php?subscribe">re-subscribe</a> at any time!
<br />
<form onsubmit="return checkForm2()" name="unsub_form" method="post" action="index.php?unsub=go">
Email: <input type="email" name="email" size="20" />
<br />
<input type="submit" value="unsubscribe" name="submit" />
</form>
<?php
}
else
{
// process unsubscription HERE
}
}
echo '</div>';
}
This is the JS for form validation (negligible I think because it works in IE and I get the same result when commenting this script out):
<script type="text/javascript" language="javascript">
function checkForm()
{
var regex = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,6}$/;
var form = document.forms.subscribe_form;
var name = form.name.value;
var email = form.email.value;
if (name == '' || email == '')
{
alert('You must enter both your name and email address!');
return false;
}
else if (!email.match(regex))
{
alert('You must enter a valid email!');
return false;
}
return true;
}
function checkForm2()
{
var form = document.forms.unsub_form;
var email = form.email.value;
if (email == '')
{
alert('You must enter an email address!');
return false;
}
return true;
}
</script>
