Validate form

[Sanchixx]

How can i stop someone from posting when this form is empty?
Here is my form:

<form name="message" action="" >
<center><input name="usermsg" type="text" id="usermsg" size="63" />
<input name="submitmsg" type="submit" id="submitmsg" value="Send" /></center>
</form>

You will have to use jquery or php to verifiy each field if it's empty and return an error
