One quick glance of an experienced eye allowed to understand the blurred
and almost unreadable vishal's handwriting:
i have one form on which the data is stored in database and suppose the
user clicks the back button of browser and again click on submit button
then the data will be saved in database again.
so how can i solve this problem????
thxs for help in advance
<H1 style='color:red; font-weight:bold; font-style:italic;
font-decoration:underline; background: green'>Now don't you even TRY to
click this button twice!</H1>
<INPUT type='submit' ...>
;)
Seriously, you could simply check if the data has been already written,
or generate a random ID in a hidden input, so that you know if data has
already been written.
