Plz help me: Form verification problem..

[Anon]

Recently I have made a user registration form(in php) with verification capability.If the user accidently ignored a required field, he/she will be given a message indicating the field must be filled in. But, I can only display the error message in different pages, with a link "click here to return to previous page".And, I found it is tedious using this way. Could it be possible for me to display the error message above the form, so that the users can easily modify the field? If could, how can I remain or show the information filled by user previously in the form? By using cookie? (Does it mean that the user must turn on the cookie option then only the information filled will be kept?) Thank you very much.

You should do it with javascript.

put this in your head tag:
<script language="JavaScript">
function validateForm(form)
{
if (form.name.value==""){
alert ("Sorry, Name can't be blank")
return false
}
if (form.telephone.value==""){
alert ("Sorry, Telephone can't be blank")
return false
}
return true
}
</script>

And this should be your form tag:
<form action="process.php" onSubmit="return validateForm(this)">

Good luck!
