export_ns_set_vars

export_ns_set_vars   { format "url" }   { exclusion_list "" }   { setid "" }

Returns all the params in an ns_set with the exception of those in exclusion_list. If no setid is provide, ns_getform is used. If format = url, a url parameter string will be returned. If format = form, a block of hidden form fragments will be returned.

Source code:

    if [empty_string_p $setid] {
	set setid [ns_getform]
    }

    set return_list [list]
    if ![empty_string_p $setid] {
        set set_size [ns_set size $setid]
        set set_counter_i 0
        while { $set_counter_i<$set_size } {
            set name [ns_set key $setid $set_counter_i]
            set value [ns_set value $setid $set_counter_i]
            if {[lsearch $exclusion_list $name] == -1 && ![empty_string_p $name]} {
                if {$format == "url"} {
                    lappend return_list "$name=[ns_urlencode $value]"
                } else {
                    lappend return_list " name=$name value=\"[philg_quote_double_quotes $value]\""
                }
            }
            incr set_counter_i
        }
    }
    if {$format == "url"} {
        return [join $return_list "&"]
    } else {
        return "<input type=hidden [join $return_list ">\n <input type=hidden "] >"
