Validation For Forms

Is there any way i can make required fields and validate email addresses so that test@test.com, etc.... cannot be put in.

the only problem with this is that test@test.com could be a valid email address. you could try this link

to find a script that will validate the entries

you can use the script below to make sure fields are filled in

<script language="javascript">

</head>
<body>

<form name="simpleform">
Name: <input type="text" size="20" name="name">
<input type="Button" value="Submit" name="Submit" onclick="checkfields()">
</form>
</body>

just add whichever fields you may require

Also, if you want to do it within your script you are submitting to (works better because some people may not have JavaScript enabled), you could do something like this:

[code:1:87aa1c7f2a]if (strlen ($email_address) < 7 || substr_count ($email_address, ".") == 0 || substr_count ($email_address, "@") != 1) $error = "Bad email";[/code:1:87aa1c7f2a]

Quick hack off the top of my head, but that would work in PHP (and other languages with minor syntax changes).

Basically makes sure the email address is 7 or more characters long, has at least 1 "." in it and one "@" in it.

You could of course go crazy with the logic, but that's a simple way to do it.

Your host will however then need need to allow you to use php scripts.

emails can be validated with Regular Expressions and the domain can be varified for accepting email using PHP

Javascript can check for fields filled in and validate the email string with Regular Expressions.

the server-side validation is the most important as like said above, some ppl don't have JavaScript on.

If you don't have PHP I could host the PHP for you in exchange for links or something.
