First time for me here.
I am using PHP, MySQL, JavaScript and running JQUERY and AJAX functions.
I have an anchor link that runs a function.
The function emptys a DIV tag and then fills/displays (SELECT query) a table of rows in the DIV with a is null where clause. Each row has a select box where the NULL data column would go. The data in the select box comes from a different table.
When the select box changes it immediately runs the ajax to UPDATE the table row with the new data in the select box.
When you click the link to run the function again (empty, select query and display based on null column) the row that was just updated to the DB shows up again based on the is null clause. Checking the DB table at this point shows that it is in fact not null and was UPDATEd properly the first go around.
The page is never refreshed during this process and never has to be. If I do refresh it shows the proper data without the BUG.
All your thoughts are greatly appreciated.
