Epd Posted July 8, 2006 Share Posted July 8, 2006 Hi, I am starting to learn php my helping a friend of mine develop a game (Yeah a bit high up for a starting point but I learn fast). I wrote the following code and was wondering how I would make it execute only after a link on the page has been clicked.[code]if(isset($_GET['repair'])) {$dbres = mysql_query("SELECT * FROM `[garage]` WHERE `id`='{$_GET['repair']}'");$car = mysql_fetch_object($dbres);if($car->car == "Renault Clio Sport") { $waard = "2400"; }elseif($car->car == "Audi A3") { $waard = "4250"; }elseif($car->car == "Bmw m3") { $waard = "6800"; }elseif($car->car == "Cadilac Escelade") { $waard = "8250"; }elseif($car->car == "Nissan Skyline") { $waard = "10000"; }elseif($car->car == "Porsche 911") { $waard = "12500"; }elseif($car->car == "GT 40") { $waard = "15000"; }elseif($car->car == "Lamborghini Murcielago") { $waard = "25000"; }elseif($car->car == "Ferrari Enzo") {$waard = "26000"; }elseif($car->car == "TVR Speed 12") {$waard = "27000"; }elseif($car->car == "Mclaren f1") {$waard = "29000"; }elseif($car->car == "Bugatti Veyron") {$waard = "30000"; }$schadelost = round($waard-($waard-((($car->damage/100)*2)*$waard)));if ($data->cash >= $schadelost) { mysql_query("UPDATE `[garage]` SET `damage`='0' WHERE `id`='{$_GET['repair']}' AND `login`='{$data->login}' AND `mission`='0'"); mysql_query("UPDATE `[users]` SET `cash`=`cash`-$schadelost WHERE `login`='{$data->login}'"); $data->cash -= $schadelost;echo "You repaired the car!";} elseecho "You haven't got enough money!";}[/code]Also if anything looks a bit wrong to anyone please let me know!Thanks!EPD Link to comment https://forums.phpfreaks.com/topic/14018-running-code-after-a-link-within-the-page-has-been-clicked/ Share on other sites More sharing options...
hvle Posted July 8, 2006 Share Posted July 8, 2006 save your code to a file, say myfile.phpdon't forget to wrap your code with <?php ?>create a html page with a link like this:<a href="myfile.php?repair=7">run my script</a>obviously, 7 is the id.when user click that link, your script executed.

Daniel0 Posted July 8, 2006 Share Posted July 8, 2006 Instead of using all those if's and else if's I would use a switch: [code]switch($car->car){ case 'Renault Clio Sport': $waard = 2400; break; case 'Audi A3': $waard = 4250; break; case 'Bmw m3': $waard = 6800; break; case 'Cadilac Escelade': $waard = 8250; break; case 'Porsche 911': $waard = 10000; break; case 'Porsche 911': $waard = 12500; break; case 'GT 40': $waard = 15000; break; case 'Lamborghini Murcielago': $waard = 25000; break; case 'Ferrari Enzo': $waard = 26000; break; case 'TVR Speed 12': $waard = 27000; break; case 'Mclaren f1': $waard = 29000; break; case 'Bugatti Veyron': $waard = 30000; break;}[/code]It takes up more space in the script, but I just think it looks nicer. The other way works perfectly too though.You can read more about switches here: http://php.net/switch Link to comment https://forums.phpfreaks.com/topic/14018-running-code-after-a-link-within-the-page-has-been-clicked/#findComment-54795 Share on other sites More sharing options...
