I have a MySQL database of orders that each have various activities associated with them. My PHP/HTML page pulls down the activities when you click an order and allows the user to change attributes of the activities with a form. On submit another PHP file loops through activities in the table and runs an update query on the database. Works great!
I have recently added a JavaScript function that will add activities to the list (appendChild, createElement...). I then added to my PHP file an INSERT
query for the new activities.
The problem is that when I run the update PHP file it is not looping through the newly added records that were added with JavaScript. I checked it by using <?php print $size = count($_POST['FcastID']) ?>
and the value doesn't change when records have been added.
The records look fine when added to the table and the id and name convention match the other records. It seems like the page needs to be refreshed before the PHP file runs.
