Question

I have a table named product_table as below with two fields product_id and comp_prod

The values for comp_prod will be sent as comma separated values like 4,3

but the value of product_id will be common

I want to insert the comma separated values as separate rows as follows with product_id as common. How can i do that using php and mysql ?

product_table

+-----+----------+-----------------+    
| id | product_id  |comp_prod      |   
+-----+----------+-----------------+    
|1  |      339     |  4            |   
|2  |      339     |  5            |   
+------------+---------------------+     

Answer 1

$pro=5;

$comp_proSplit= explode(",", $comp_pro);

$cnt=count($comp_proSplit);

for($i=0;$i<$cnt;$i++)
{
mysql_query("insert into product_table(product_id,comp_prod) 
values ($pro, $comp_proSplit[$i])");
}

Hope it helps
