I have the same question, but the solution is simple, thanks for the support of the folks at www.webune.com i was able to get this question answer. I do all my web hosting with webune and I am very pleased with their service. The tech at webune said i can do this with PHP. Since i have all my hosting with them, php is standard in all their packages.
so the funtion to use in php to limit the least amount of character a user can enter is the strlen() function.
ok, to follow the contact us form example for the user's name, so once the user submits their name, i would use something like this to check the form to make sure the user's name in 3 or more character long otherwise, the form will fail, so this is the html i would use:
Code:
<!-- ##### BEGIN HTML CODE ##### -->
<form method="post" action="this_file.php">
<p>Name:
<input type="textfield" name="name">
</p>
<p>
<input type="submit" name="submit" value="Submit">
</p>
</form>
<!-- ##### BEGIN HTML CODE ##### -->
<?
###### PHP CODE BEGIN #########
f(strlen($_POST[name]) > 3)
{
echo "Your Name is Valid";
}
else
{
echo "Sorry, Your name must contain atleast three characters;
}
###### PHP CODE END #########
?>
