codergirl93 Posted February 6, 2014 Share Posted February 6, 2014 Okay, so I'm writing a simple fishing game loop but I'm having multiple issues. I have some images in a folder, and I set an array with the filename as key and the type of fish as the value.I then set it up to do this: echo "Nice one! You caught a " . $fish[$rand] . "!"; and $rand is picking a random fish from the array. First, I need a way to output the image of the fish that goes along with the name. I want this to happen upon the submit input button (which I don't know how to hook up). Second, right now I have a loop that outputs each file in the img folder. It's also outputting .DS_Store. I'm trying to exclude that from outputting. I have a foreach loop that is attempting to do just that, but I used var_dump on 3 variables and here's the output: A) ($filename) string(1) "." string(2) ".." string(9) ".DS_Store" string(11) "catfish.gif" string(10) "lmbass.gif" string(10) "minnow.gif" string(9) "perch.gif" string(12) "pickerel.gif" string(10) "shiner.gif" string(10) "smbass.gif" string(11) "sunfish.gif" B) ($filepath)s string(5) "/img." string(6) "/img.." string(13) "/img.DS_Store" string(15) "/imgcatfish.gif" string(14) "/imglmbass.gif" string(14) "/imgminnow.gif" string(13) "/imgperch.gif" string(16) "/imgpickerel.gif" string(14) "/imgshiner.gif" string(14) "/imgsmbass.gif" string(15) "/imgsunfish.gif" The proper filepath should be /img/filename.gif. Also, what are string(5) "/img." and string(6) "/img.."? C) ($root_dir) NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL Is $root_dir even necessary? Third, I want there to be a random chance that they will catch nothing; when a fish is caught, it would say echo "Nice one! You caught a " . $fish[$rand] . "!"; but if nothing is caught it would say echo "Uh-oh, looks like that one got away!"; Last, I have audio that I want to play when a fish is not caught. Here's all of my code: <div class="container"> <div class="starter-template"> <h2>Catch a Fish!</h2> <p class="fishes"> <form action="fishing.php" method="post"> <?php $fish = array('catfish.gif' => 'catfish', 'lmbass.gif' => 'large-mouth bass', 'smbass.gif' => 'small-mouth bass', 'shiner.gif' => 'shiner', 'perch.gif' => 'perch', 'pickerel.gif' => 'pickerel', 'minnow.gif' => 'minnow', 'sunfish.gif' => 'sunfish'); $rand = array_rand($fish); //link file name (key) to value echo "Nice one! You caught a " . $fish[$rand] . "!"; $files = scandir('img'); if ($files !== false) { foreach($files as $f) { if ($f == '..' || $f == '.') continue; echo '<li class="fish_pic"><img src="img/'.$f.'" alt="'.$f.'" title="" class="fish"></li>'."\n"; } } $files = scandir('img'); $extensions = array(".txt",".DS_Store"); // Loop through each filename of scandir foreach ($files as $filename) { // Construct a full path $filepath = '/'.'img'.$filename; //var_dump($filename); //var_dump($filepath); //var_dump($root_dir); // Is it a file? If so, get the extension using some function you created if(is_file($filepath)) { $ext = getFileExtension($filename); // Is the file extension not included in the array of forbidden extensions? // Since it is not included, execute code to list the file or whatever if (!in_array($ext,$extensions)) { // Code for files not excluded } } } ?> </p> <p><input type="submit" class="btn btn-primary" value="Go Fishing!"></p> </form> <audio controls> <source src="audio/missed.ogg" type="audio/ogg"> <source src="audio/missed.mp3" type="audio/mpeg"> <p>Your browser does not support the audio element.</p> </audio> <div class="clearfix"></div> </div><!-- close .starter-template --> </div><!-- /.container --> One last note, my folder/file structure are all at the root. So fishing.php and /audio and /css and /img are all on the same level. I know this is a lot but I've googled every single issue and tried numerous things and nothing seems to work. Any help I could get would be extremely appreciated!! :-) Quote Link to comment Share on other sites More sharing options...

It is returning null for $root_dir because you have not defined it. Edited February 6, 2014 by Ch0cu3r Quote Link to comment Share on other sites More sharing options...
