kaiman Posted March 26, 2012 Share Posted March 26, 2012 Hi All, I have a rudimentary PHP page that displays a quote a day (366 quotes) from a text file. I have implemented sessions and javascript to account for the users time offset and this seems to be working well. As this is going to be for a iPhone mobile web app, I don't have to worry about DST or users having their computers time set incorrectly (the time is set automatically via cell towers by the service providers) The challenge now is that I would like to be able add Next and Previous links which would allow users to view a quote of the day from past and future dates. I have tried to implement it using the GET parameter like this: // get day settings $day = (int) ($_GET['day'] ? $_GET['day'] : date('z')); // next quote link echo $next_quote_link = '<a href="?day='.($day != 366 ? $day + 1 : 1).'">Next Quote >></a>'; // previous quote link echo $previous_quote_link = '<a href="?day='.($day != 1 ? $day - 1 : 366).'"><< Previous Quote</a>'; but it seems to just return the same quote and date. Can someone help me figure out what I've overlooked or need to do to pass the date to the script correctly? Any help is appreciated Thanks in advance, kaiman Here is the complete script so far: <?php // start session session_start(); // get timezone offset if(!isset($_SESSION['timezone'])) { if(!isset($_REQUEST['offset'])) { ?> <script type="text/javascript"> var d = new Date() var offset= -d.getTimezoneOffset()/60; location.href = "<?php echo $_SERVER['PHP_SELF']; ?>?offset="+offset; </script> <?php } else { $zonelist = array('Kwajalein' => -12.00, 'Pacific/Midway' => -11.00, 'Pacific/Honolulu' => -10.00, 'America/Anchorage' => -9.00, 'America/Los_Angeles' => -8.00, 'America/Denver' => -7.00, 'America/Tegucigalpa' => -6.00, 'America/New_York' => -5.00, 'America/Caracas' => -4.30, 'America/Halifax' => -4.00, 'America/St_Johns' => -3.30, 'America/Argentina/Buenos_Aires' => -3.00, 'America/Sao_Paulo' => -3.00, 'Atlantic/South_Georgia' => -2.00, 'Atlantic/Azores' => -1.00, 'Europe/Dublin' => 0, 'Europe/Belgrade' => 1.00, 'Europe/Minsk' => 2.00, 'Asia/Kuwait' => 3.00, 'Asia/Tehran' => 3.30, 'Asia/Muscat' => 4.00, 'Asia/Yekaterinburg' => 5.00, 'Asia/Kolkata' => 5.30, 'Asia/Katmandu' => 5.45, 'Asia/Dhaka' => 6.00, 'Asia/Rangoon' => 6.30, 'Asia/Krasnoyarsk' => 7.00, 'Asia/Brunei' => 8.00, 'Asia/Seoul' => 9.00, 'Australia/Darwin' => 9.30, 'Australia/Canberra' => 10.00, 'Asia/Magadan' => 11.00, 'Pacific/Fiji' => 12.00, 'Pacific/Tongatapu' => 13.00); $index = array_keys($zonelist, $_REQUEST['offset']); $_SESSION['timezone'] = $index[0]; } } // store timezone offset in session date_default_timezone_set($_SESSION['timezone']); ?> <html> <head> </head> <body> <?php // display the date echo "<h3>\n"; echo date("l, F jS, Y\n"); echo "</h3>\n"; // display the quote $lines = file("quotes.txt"); $day = date("z"); echo "<p>“".$lines[$day]."”<p>\n"; ?> </body> </html> Quote Link to comment Share on other sites More sharing options...

Jessica Posted March 27, 2012 Share Posted March 27, 2012 You create $day on the line right before your output. $day = date("z"); echo "<p>“".$lines[$day]."”<p>\n"; You'll need to put your code in that area that checks if a day was sent in the URL, and if not use the current day.
