here my problem I couldn’t solve.
I have a multiple register with 10 records.
In the left row I can mark for example record number 1,3,6 and 7. The other records rest unmarked. (I use the checkbox in the left row)
I define a button and I want to define a PHP loop, so that I can to something with the marked records without effecting the other records. For example I want to increase then price of the marked products. update proce set proce = price * 1.1
But how do I get the promary key of evere record and how can I test, wheter the record was marked in checkbox or not…
