Form Validation - NEED HELP!

[Anon]

PART 1.

I need to create a form and attach some code that will validate the entries.

The form is very basic, with just 5 fields...

Name, Domain, Speed, Message, and Email Address.

Now what I need to do is check that each field was completed and that the email has valid syntax (???@???.???)

PART 2.

If the form was completed correctly they are directed to a success page where their entried are displayed on the page and the data is also submitted to a MySQL database, otherwise they are told that X field was not filled in, and the form is redisplayed with the other data there and the missing field highlighted.

I understand that this may be a tall order to ask for someone to tell me of a program that already exists that does ALL of this, which is why I am seeking help to create one.

however if you do know of a script that does ALL the above then please tell me about it.

Regards,

Charles,

'fraid your only way to do this without sending the page forwards and backwards a lot is to use javascript.

I had a form that did this before, but no longer have the code.

As I recall it submitted the data to itself in the forms action="form_name.php" element.

and had code something like...

if ($filed1 = "") || ($filed2 = "") || ($filed3 = "") || ($filed4 = "") || ($filed5 = "") {
...
}

else {
echo $form_success;
}

but I can not figure out the email validation and so on!

So it did not have to keep going back and forth

I am also making use of sessions, so I could store the variables in there and on a succesful submit of the form, clear/unload the variables again

the going back and forth is not an issue as long as the entered fields are remembered and filled in for the user!

hope this helps

Using javascript you can stop the form submitting before all the data is valid. There is information on this, including email validation at http://www.jsworld.com

hope this helps

Charlie,

Thanks muchly. I've found some old javascript code which does the same sort of thing.

If it's any use to you:

The form is scarily enough called form1.
The submit button looks like:

<input type='submit' value='Save Changes' OnClick='return validate_entries()'>

and the validate_entries() function looks like:

function validate_entries()
{
if ( document.form1.forename.value == '')
{
alert("Sorry, please enter forename");
return false;
}

if ( document.form1.surname.value == '')
	{
	alert("Sorry, please enter surname");
	return false;
	}

return true
}

Where (again) unsurprisingly enough forename and surname are two text input fields.

Cheers

deos this look like I am dragging my feet?

If so, sorry!

but...

I still need email syntax validation, which is a biggie in this case.

Also, I have never used JavaScript to insert into a MySQL D-Base

Any leads for this?

I was told to look at:
<a href="http://www.jsworld.com">http://www.jsworld.com</a> but that does not appear to be active.

Thank you for all your time and efforts to help me resolve this matter.

NOTE: in the code in a previous post to this thread I typed '$filed', and copied it 5 times - DOH - I just wish to make it clear, I can spell '$field' - lol

JS code:

function checkMail()
{
var x = document.forms[0].email.value;
var filter = /^{([a-zA-Z0-9_.-])+@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9])+$/;}
if (filter.test(x)){
alert('YES! Correct email address');
document.yourformnamehere.submit();
}else alert('NO! Incorrect email address');
}

i got it from
http://www.xs4all.nl/~ppk/js/mailcheck.html

and just added the line "document.yourformnamehere.submit();", so that your for is sent to the php file (or asp or whatever) ...

you call this function like this:

<form action="some.php" method="post" name="ourformnamehere" onSubmit="checkMail();">
email : <input name="email">
</form>

try and ask again if it was not detailed enough
