mysql - Adding rows to database from a dynamic form in PHP -

-

i have form index parts belong schematic drawings. have hundreds of drawings , each 1 have different number of parts attached it. each part requires 3 pieces of information number, part_id , description. initial form captures , allows user add many rows form needed parts drawing. form fields named number_1, part_id_1 , description_1. each row added form increments number @ end one. example if schematic has 10 parts end number_1 - number_10.

while ($i <= $fieldnum) {              $number = "number_".$i;              $partnumber = "partnumber_".$i;              $description = "description_".$i;              print ("            <input name=$number type=\"text\" size=\"3\" />            <input name=$partnumber type=\"text\" size=\"20\"  />            <input name=$description type=\"text\" size=\"35\" />                     ");              $i++;             }

where i'm stuck getting data mysql database. each form row needs become row in database. if static form easy, each form element having dynamic name don't know how proceed.

use 2 tables. create table schematic. create table parts, , assign foreign key id of schematic.
