  20 # This script search in items table if a value for a given field exists.
  21 # It is used in check_additem (additem.js)
  22 # Parameters are a list of 'field', which must be field names in items table
  23 # and a list of 'value', which are the corresponding value to check
  24 # Eg. @field = ('barcode', 'barcode', 'stocknumber')
  25 #     @value = ('1234', '1235', 'ABC')
  26 #     The script will check if there is already an item with barcode '1234',
  27 #     then an item with barcode '1235', and finally check if there is an item
  28 #     with stocknumber 'ABC'
  29 # It returns a JSON string which contains what have been found
  30 # Eg. { barcode: ['1234', '1235'], stocknumber: ['ABC'] }
