ขอคำแนะนำเรื่องการลบข้อมูล พร้อม Update ข้อมูลไปพร้อมๆกันครับ |
|
|
|
|
|
|
|
คือ ตอนกดลบต้องทำลบพร้อมกับ update(product_qty) ไปพร้อมๆกัน ทำทั้งสองอย่างใช้คิวรี่สองอันเลย เอาค่าที่ลบมา update
เพราะฉะนั้นก่อนลบต้องไปเอาค่ามาก่อนมาเก็บไว้ก่อนทำไว้เพื่อจะได้รู้ว่าจะต้องลบเท่าไหร่
หลักการ
ตอนกดปุ่มลบทำ 3 อย่าง ดึงค่ามาเก็บไว้ก่อน,ได้ค่าแล้วลบอันนั้นทิ้ง,ค่าที่เก็บมาเอาไป update กับของเดิม
อย่างเช่น
54 (จำนวนสินค้าโคคาโคล่าในหน้า product)
-1 (มีการซื้อไปหนึ่งชิ้น)
=53 (ยอดที่เหลือ)
ไปลบ รายการที่ 97 ที่มี 30 ชิ้น
53-30
=23 (นี่คือยอดจริงๆที่ควรมีอยู่ในproduct สินค้าที่ 1 โคคาโคล่า)
หน้า product
หน้า purchase_detail เวลากดลบก็มี update จำนวนที่product_qty หน้า product ทันที
ฐานข้อมูล Product
ฐานข้อมูล purchase_detail
code product.php

ยาวไปไม่อ่าน
เอาแค่ delete + update ก็ใช้ transection สิ

ใช้ Transection สิ
Code (PHP)
mysql_query("BEGIN");
$num = x; //qty สำหรับลบและ update
$query1: delete ข้อมูล
$query2: update ข้อมูล
$query3: อื่นๆ ถ้ามี
if(($query1) && ($query2)) // if(($query1) && ($query2) && ($query3))
{
mysql_query("COMMIT");
}
else
{
mysql_query("ROLLBACK");
}
CI
Code (PHP)
$this->db->trans_begin();
$this->db->query('DELTE QUERY...');
$this->db->query('UPDATE QUERY...');
$this->db->query('อื่นๆ...');
if ($this->db->trans_status() === FALSE)
{
$this->db->trans_rollback();
}
else
{
$this->db->trans_commit();
}
เจริญพร...
