First off thanks for the reply.
When I click the "test" button I get "Error: 'length' is null or not an
object."
I used
<script language=javascript>
function func( field ) {
for ( i = 0; i < field.length; i++ )
field[i].checked = true ;
}
</script>
<input type="checkbox" name="email[]" value="5">
<input type="checkbox" name="email[]" value="2">
<input type="checkbox" name="email[]" value="1">
<input type=button value=test onclick="func( document.forms[ 0
].elements[ 'email[]' ] )">

onClick="checkAll(document.myform.email)" and my check boxes have to have
name="email" but i need to name them name="email[]" in order to pass the
variables as an array in php. ive tried using
onClick="checkAll(document.myform.email[])" but that just gives me an error
for obvious reasons im sure. I don't know jack about javascript, so if you
know of a better way to make a button that selects all check boxes or
another way to code how the check boxes values are passed to the next page,
I would be so greatful.
