RE: [PHP] Double Click

If you are lucky and are feeding this form data to a database, you can create a unique hash field from other fields that would not change from click 1 to click 2. Then just make the database treat the hash as a unique index and it should prevent double entries. Works for me. Other advice is to not tell the double clicker that had an error; Just silently ignore their second request. > -----Original Message----- > From: Manuel Lemos [mailto:mlemos@acm.org] > Sent: Wednesday, February 28, 2001 2:55 PM > To: php-general@lists.php.net > Subject: Re: [PHP] Double Click > > > Hello Fabian, > > On 28-Feb-01 03:01:02, you wrote: > > > >Hi, > > >I have a page, and when I have to add a product I use a form, > many people are > >used to make double click in every task, so when the product is > sent with a > >double click in the send button, the program send it twice to > the data base. > > >What can I do to prevent this? > > You may want to try this forms generation class that lets you define a > warning message that shows when the user attempts to submit a form more > than once. > > http://phpclasses.UpperDesign.com/browse.html/package/1 > > Regards, > Manuel Lemos > > Web Programming Components using PHP Classes. > Look at: http://phpclasses.UpperDesign.com/?user=mlemos@acm.org > -- > E-mail: mlemos@acm.org > URL: http://www.mlemos.e-na.net/ > PGP key: http://www.mlemos.e-na.net/ManuelLemos.pgp > -- > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net > For additional commands, e-mail: php-general-help@lists.php.net > To contact the list administrators, e-mail: php-list-admin@lists.php.net >
