November 29, 200817 yr Funny that the example on the website you got it from does not work either... I will take a look though
November 29, 200817 yr I tried this and it works perfectly Put this after the calendar class: $d = getdate(time()); $month = $d['mon']; $year = $d['year']; if(isset($_GET['month'])) { if( (is_numeric($_GET['month'])) && ($_GET['month'] <= 12) && ($_GET['month'] >= 1) ) { $month = $_GET['month']; } } if(isset($_GET['year'])) { if( (is_numeric($_GET['year'])) && ($_GET['year'] <= 9999) && ($_GET['year'] >= 1970) ) { $year = $_GET['year']; } } $cal = new MyCalendar; echo $cal->getMonthView($month, $year); Works here: http://www.ajrdev.com/cal.php

November 29, 200817 yr Yea that would work, essentially the same as my example except mine includes a bit more validation to stop it breaking if the $_GET variables have invalid values
November 29, 200817 yr Yea that would work, essentially the same as my example except mine includes a bit more validation to stop it breaking if the $_GET variables have invalid values I left the validation out because this is not a user input from a form. The previous month and next month are calculated within the class there fore I think the validation is redundant in this case, just to make the solution simple and understandable I just stated the neccessary code.

November 29, 200817 yr I left the validation out because this is not a user input from a form. The previous month and next month are calculated within the class there fore I think the validation is redundant in this case, just to make the solution simple and understandable I just stated the neccessary code. But I think If your are going to extend this program to allow user input then you would implemnt something like what you have sated
December 5, 200817 yr I left the validation out because this is not a user input from a form. theres nothing wrong with validating all input however... and $_GET[''] is still user input... just pointing it out as ALL input should ALLWAYS be validated... one thing i do is validate ALL input and save it to a new array replacing $_POST/$_GET with $clean['array_key'], im sure skysurge, Jem and other coders/x-hackers will agree that all it takes is one code screw up to cripple an entire system... its a coding mentality thing really... you don't want to get in a habit of saying ahh that dosnt need validating because X, Y & Z..... because what if Y fails... what's gonna stop unwanted activity on your system? maybe im just over paranoid... but then its not paranoia if its true....
December 5, 200817 yr for instance what if an attacker trys to abuse your lack of validation with an attacking loading this up http://www.webviews.co.uk/weather/id.txt that is from a real script attack attempted today on one of my servers, and is still being used by the attacker on other sites... obviously it dint go through, my system just reported it to me and applied a automatic network ban... that was an attack using the $_GET route into the application... so yeah don't trust any input unless your system created it
