Randy,
You can use PHP to check if fields should be hidden at runtime and
Javascript to then update fields as the user interacts with the form.
So injecting <?php if($this->data['ModelName']['type'] == 1) echo "
style='display:none'"; ?> into your $this->Form-
>input('ModelName.asset') call would set the state on page load and
your Javascript function could then deal with any changes in state.
On a side note, you have made an excellent choice in using CakePHP as
your preferred PHP Framework, so why not also use a framework for
Javascript? I prefer jQuery (previously used prototype, but found
jQuery is now a much bigger more updated project) and to do what you
want would simply be a matter of:
// if only two type values to choose from
$( document ).ready(function() {
if( $( '#ModelNameType' ).val() != 1 ) {
$( '#ModelNameAsset' ).hide(); // hide asset on page load
}
$( '#ModelNameType' ).change(function() {
$( '#ModelNameAsset' ).toggle();
});
});
// if more than two type values to choose from
$( document ).ready(function() {
$( '#ModelNameType' ).change(function() {
typeChange( this.val() );
});
function typeChange(val) {
if( val == 1 ) {
$( '#ModelNameAsset' ).show();
} else {
$( '#ModelNameAsset' ).hide();
}
}
});
Not tested the above, but it's fairly basic stuff so should work if no
typos :)
HTH, Paul.
