POS System in PHP Part 13: Create Order - Product Quantity Increment & Decrement using jQuery in PHP

[@davidadomako5004]

I added location.reload() after both increment and decrement script and it works.

Hello sir thank you for this amazing project ❤ I have a question and I'd like you to give me some ideas, I'd like to validate the quantity availability in the database when I press the + button in order to sell only the product that I have in stock, not more. I hope you can help me, thank you 🙏🙏🙏❤️❤️❤️

17:00 Hello sir, I have a problem. When I click the +/- button, the quantity gets updated but not the total price. After updating the quantity and pressing “Ctrl + R” (refreshing the page) then my price gets updated. How should I fix the problem? Thanks in advance.

Hi have shown this in the last of video, that how to refresh the complete div area without page reload or refresh

[@fundaofwebit]

19:55 and continue to see reload without page refresh. So it automatically calculates the total price

[@fundaofwebit]

​ @abdulazizbah1418 19:55 and continue to see reload without page refresh. So it automatically calculates the total price

[@abdulazizbah1418]

It did that way but result

[@kenzy-rwb]

sir when i click on increment and decrement it said Uncaught SyntaxError: Unexpected token '

[@fundaofwebit]

There is an error in your code. Please inspect and go to Networks tab and then click on increment or decrememt button, you will seeing the request in it and catch the error / bug.

SAME PROBLEM I FIX MINE IN THIS LINE BEFORE IT IS LIKE THIS $_SESSION['productItems'][$key]['quantity'] = $quantity; but then i see this $prodData = [ 'product_id' => $row['id'], 'name' => $row['name'], 'image' => $row['image'], 'Retail_Prize' => $row['Retail_Prize'], 'Quantity' => $quantity, ]; the right answer is $_SESSION['productItems'][$key]['Quantity']

[@md.abdurrashid1672]

productId is not defined, how to solve the problem.

[@davidadomako5004]

Hello Sir, Please I have tried this 19:55 but it does not still automatically calculates the total price. The $().load() function still doesn't work.

[@fundaofwebit]

$('#productArea').load(' #productContent'); in this above load() function, there is space in the beginning of the bracket of the load function.

Double messages are showing blue and red color at a same time "Quantity Updated" ! why?

[@fundaofwebit]

May be by mistake you have added alertify() 2 times on particular event.

[@abdulazizbah1418]

Price not updating

[@fundaofwebit]

Just inspeact the browser and move to console and network tabs and see what's happening when clicking on update price. So this is how we can find what's going on and why price is not updating. By seeing the error on console and network tab

[@hamededasd]

​@FundaOfWebIT when add item is working but if add more items price not updating and show some error as double message in console and error in JSON.parse

[@abdulazizbah1418]

Whay don't you answer to people's question

[@fundaofwebit]

19:55 and continue to see reload without page refresh.
