PHP-将相同字段插入mysql

Question

PHP - Inserting Into Xampp/ Mysql

iam making product database with insert php like this

  $save_sale = mysql_query("INSERT INTO sale(no_receipt,no_confirm,time,date,day,total) values
         ('$_POST[no_receipt]',
          '$_POST[no_confirm]',
          '$hour_now',
          '$date_now',
          '$day_now',
          '$_POST[total]')")
         or die(mysql_error());
  $save_sale_detail =  mysql_query("INSERT INTO sale_detail(no_receipt,id_product,quantity,price,subtotal) values
         ('$_POST[no_receipt]',
          '$_POST[id_product]',
          '$_POST[quantity]',
          '$_POST[price]',
          '$_POST[subtotal]')")
         or die(mysql_error());

but it just save one transaction every time i submit multipple product order with different quantity, price and subtotal. i was meaning something like in sale saving and create no_receipt and then sale_detail create no_receipt too following sale . example : Sale

     No. Receipt  = 001
     No. Confirm  = 205850 <-- it just confirmation order
     hour         = 17.00
     date         = 31/08/2013
     day          = saturday
     total        = $770 <-- subtotal calculation

     sale_detail
     No. Receipt  = 001
     id_product   = 1 <-- let say it's a hat
     quantity     = 3
     price        = $150 <-- price by each product
     subtotal     = $450 <-- price * quantity
     ----- and come other product order ---
     sale_detail
     No. Receipt  = 001
     id_product   = 4 <-- let's say it's a glasses
     quantity     = 4
     price        = $80 <-- price by each product
     subtotal     = $320 <-- price * quantity
     ----- and come other.. ---------------

but i stuck and just can saving one transaction, if sale _detail success to saving, the sale still empty.

any help would be appreciate..

You need to POST the per-product details as an array. In the markup you would use <input name="id_product[]"..../>

This will then be received in PHP as an array ( echo gettype($_POST['id_product']) will output array ).

Then you can loop through with foreach ($_POST['id_product'] as $id) or something else, and call your INSERT INTO sale_detail... query multiple times (once per loop iteration).

Note that you only want to put [] in the name attribute of the values that actually are per-item. For example the no_invoice field is a single value, not an array, so you would just use name="no_invoice" and not name="no_invoice[]" .
