Count articles in categories

[RazorMaster]

Hi all,

Probably I'm posting a repeated question, but I cannot find my answer...

1 - I'm trying to add articles count in front my categories. Ex:

Category 1 (37)
Sub-Cat 1 (12)
Sub-Cat 2 (25)
Category 2 (18)
Sub-Cat 1 (8)
Sub-Cat 2 (10)

Is there any script or javascript to do this? What changes do I need to make in my php code?

2 - How can I restrict a maximum number of checkboxes selected?

This is my javascript code:

var max_categories=5;
function count(formname)
{
    var j=0, i, el;
    for (i=0; i<formname.elements.length; i++) {
    el = formname.elements[i];
    if (el.type=="checkbox" && el.name=="jobtype[{JOBTYPES.id}]" && el.checked) j++;
    }
    if (j>=max_categories)
        for (i=0; i<formname.elements.length; i++) 
        {
        el = formname.elements[i]
        if (el.type=="checkbox" && el.name=="jobtype[{JOBTYPES.id}]" && !el.checked) 
            el.disabled = true;
         }
    else
        for (i=0; i<formname.elements.length; i++) 
        formname.elements[i].disabled = false;
} 

and this is the output checkboxes to the categories:

<input type="checkbox" onClick="count(this.form)" name="jobtype[{JOBTYPES.id}]" value="{JOBTYPES.id}">{JOBTYPES.title}

When I use this, it still could be selected more than 5 categories...

Any help please?

Thanks.
