Re: $_POST['xxx'] = "blabla" ?

I speak under correction but the reason could be that if someone tries to hack your site, for example I post to your HTML page, you want to check it your $_POST contains a certain variable (which may be hidden) Not really sure besides that >>> Perry Jönsson <public@combinative.se> 11/22/2004 10:57:23 PM >>> Jay Blanchard wrote: > [snip] > What is the difference between these two examples? > Both works fine for me. > > > > 1. if ($_POST['submit'] == 'Login') { > ... > ... > } > > 2. if (isset($_POST['submit']) { > ... > ... > } > [/snip] > > One is checking if $_POST contains a specific value, the other just checks to see if it > contains a value. If $_POST['submit'] contains 'foo' is ISSET. Make sense? Maybe a daft question but why would you like to check for a specific value? Can you give an example when this is a good thing to do? /PJ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -------------------------------------------------------------------- Disclaimer This e-mail transmission contains confidential information, which is the property of the sender.
