define rule

This is not related to Emearld 9. It is only rights management. Here is what I did тку on this forum.

1. In form template paramters turn of accesses field.
2. In custom template add this element to the form

<div class="control-group">
    <label id="category-lbl" for="category" class="control-label"></label>
    <div class="controls">
        <label class="checkbox">
            inpu type="checkbox" id="privat-chk" item->access == 3 ? 'checked' : null); ?>/> Private 
            <small>If checked, this topic will be visible only for official support staff members.</small>
            <input type="hidden" id="jform_access" name="jform[access]" value="" />
        </label>
    </div>
</div>

And add thisjavascript at the bottom of the form.

(function($){
    $('#privat-chk').change(function(){
        setval(this);
    });

    setval(document.getElementById('privat-chk'));

    function setval(el) {
        $('#jform_access').val('1');
        if(el.checked) {
            $('#jform_access').val('3');
        }
    }        
}(jQuery))

This is custom access level form element in form of checkbox. it is either 1 - public or 3 - special. Special means only article author amd administrators will be able to access it.
