TOPIC: how to set order multiple

Thanks for the 14 day trial, works great. I'm working through things to determine if it fits my requirements. All seems good so far except for 1 item. I have need to control the order quantity multiple. My order items must always be ordered in multiples of 10 (maybe other multiple in different categories also). I see no control for this and I'm wondering what my options might be.

Did you get an answer to this?

No but managed to customize some code to provide the required functions.
Change was made to
administrator/components/com_ipricecalc/helpers/html.php
around line 553
changed:
"var qty_el = document.getElementById('i_$i'); var qty = qty_el.value; if( !isNaN( qty )) qty_el.value++; else qty_el.value=1; check_event(qty_el); return false;",
"var qty_el = document.getElementById('i_$i'); var qty = qty_el.value; if( !isNaN( qty ) && qty>0) qty_el.value--; else qty_el.value=0; check_event(qty_el); return false;"

to

/* vjm */
$mult = 10;
if (substr($item->section,0,4) == "Gift") {$mult = 25;}

echo JHTMLIpriceList::upperDownArrows(
/* vjm ***
"var qty_el = document.getElementById('i_$i'); var qty = qty_el.value; if( !isNaN( qty )) qty_el.value++; else qty_el.value=1; check_event(qty_el); return false;",
"var qty_el = document.getElementById('i_$i'); var qty = qty_el.value; if( !isNaN( qty ) && qty>0) qty_el.value--; else qty_el.value=0; check_event(qty_el); return false;"
*/
"var qty_el = document.getElementById('i_$i'); var qty = qty_el.value; if( !isNaN( qty )) qty_el.value = +qty + $mult; else qty_el.value=$mult; check_event(qty_el); return false;",
"var qty_el = document.getElementById('i_$i'); var qty = qty_el.value; if( !isNaN( qty ) && qty>0) qty_el.value = +qty - $mult; else qty_el.value=0; check_event(qty_el); return false;"

I have need to 2 different multiples depending on the section/item being used.

hope this helps.
