Hi,
I was making PHP-SQL code to automatically update the database by using the webpage interface,
Eg: To evaluate answer sheets,
1)So from the database automatically the row (Questions and answers) are fetched from database
2)The evaluator evaluates and enter the marks and it gets updated in database.
The problem im facing in the code is ,in automatic allocation of the Questions and answers from database, if 5 evaluators are working they all are getting the same one ,
Is there any way to solve this problem so that,when an evaluator gets the row ,it gets locked till he enters the mark and submit.
Can anyone plz help
thnx
