PHP Function Page Advice

Posted on 16th Feb 2014 by admin

Hi All, I am quite new to PHP and Javascript but have written an Online Shop (Mainly for Fun and education)

It uses MySQL for the Shop Item Data and a 'Username.txt' file for each users cart. (Formated as 'ItemID1xQty1, ItemID2xQty2' etc....

From the Cart View window, the user can edit the Quantity (Form text field).
When the 'Update Cart' Form button is clicked, a Javascript function;
re-calculates the monetry valuesdisplays the changesCreates a String containing the new cart dataCalls a PHP page (cart_update.php), that writes the Data to the UserName.txt file
This all works fine, except......
cart_update.php needs to do it's stuff and close. - But it doesn't close so the user is left with a blank window that has to be closed manually.

The cart data is posted from hidden form elements to cart_update.php.
using javascript to close the window results in the 'Do you want To Close this Window' message..
using JS History or $_SERVER['HTTP_REFERER'] refreshes the Cart View window to its pre-edited state

Is there a way round this..?
Can I put the cart_update.php code somewhere other than a .php page?

So close but so far..

Any help will be greatly appreciated..
