nickharambee Posted April 4, 2011 Share Posted April 4, 2011 Hi, I am using an array which allows me to prevent particular subfolders from being included in a script that generates an audio playlist. It looks like this: $disallowed=array('..', '.', 'simon', 'steve'); I would like to find a way of disallowing any folders which are empty, or, perhaps, better still, disallowing folders that do not have any MP3s in them (in case the script interprets folders as not empty if they contain system files which are automatically generated). Would someone be able to help with this? Thanks, Nick Quote Link to comment Share on other sites More sharing options...
j9sjam3 Posted April 4, 2011 Share Posted April 4, 2011 Why couldn't you just make an allowed array instead? Would save a lot of trouble... Quote Link to comment Share on other sites More sharing options...
nickharambee Posted April 4, 2011 Author Share Posted April 4, 2011 I have an allowed array too, which specifies filetypes, i.e. $allowedfiletypes=array('mp3'); but this still adds empty folders to the folder list that is generated. Here is the full script: <?php /* * ===================== * FUNctions * ===================== */ /* * array subvalue sort -- from: http://www.firsttube.com/read/sorting-a-multi-dimensional-array-with-php/ * * this function lets me sort the multidimensional array containing song/artist information by the file modified time, a subvalue */ function subval_sort($a,$subkey) { foreach($a as $k=>$v) { $b[$k] = strtolower($v[$subkey]); } arsort($b); //change this to 'asort' for ascending foreach($b as $key=>$val) { $c[] = $a[$key]; } return $c; } /* * function written to clean up my messy code (too many slashes ... display '/' as '»' (>>) for user friendliness ) */ function clean($dirty, $type='general', $debug=false){ //debug if($debug==true) echo'<br />value before clean: '.$dirty.' (first character: '.substr($dirty, 0, 1).')'; /* * General cleaning -- remove '/' at front and end */ if(substr($dirty, 0, 1)=='/'){ //echo'<br />found leading /'; $dirty=substr($dirty, 1, strlen($dirty)-1); } if(substr($dirty, -1)=='/') $dirty=substr($dirty, 0, strlen($dirty)-1); //prepare the subfolder display information by type if($type=='link') $dirty=str_replace(array('//','»'), array('/', '/'), $dirty); else if($type=='display') $dirty=str_replace(array('///','//','/'), array('»','»', '»'), $dirty); else $dirty=str_replace('»', '/', $dirty); if($debug==true)echo' | after clean: '.$dirty; //return return $dirty; } function makelink($linkme, $debug=false){ $link=str_replace('»', '/', $linkme); $link=str_replace('//', '/', $link); return $link; } function recursiveGetSongs($directory, $fileinfo, $useID3, $getID3, $parent=null, $debug, $filtered=null){ /* * configure function here: * * _usage_ * > the disallowed array should include any folders or files you explicitely don't want displayed * > the allowedfiletypes array should include any file extentions you want to play */ $disallowed=array('..', '.', 'simon', 'steve'); $allowedfiletypes=array('mp3'); if($filtered!=null){ $disallowed=array_merge((array)$filtered, (array)$disallowed); } //simple error fix if($directory=='./') $directory='.'; //debug if ($debug==true)echo'Dir to open: '.$directory; //open directory $dir = opendir($directory); while ($read = readdir($dir)) { //if ( !in_array($read, $disallowed) AND ( $filter!=null AND in_array($read, $filter) ) ) if ( !in_array($read, $disallowed) ) { if($debug==true)echo $read.'<br />'; //if is not dir, handle file if ( !is_dir($directory.'/'.$read) ){ if($debug==true)echo '^^ not dir | dir: '.$directory.'<br />'; if( in_array(substr($read, -3, 3), $allowedfiletypes) ){ if($useID3==TRUE){ //store id3 info $FullFileName = realpath($directory.'/'.$read); if($debug==TRUE)echo'<br />FFN » '.$FullFileName; $ThisFileInfo = $getID3->analyze($FullFileName); getid3_lib::CopyTagsToComments($ThisFileInfo); $fileinfo[$read]['artist']=$ThisFileInfo['comments_html']['artist'][0]; $fileinfo[$read]['title']=$ThisFileInfo['comments_html']['title'][0]; $fileinfo[$read]['album']=$ThisFileInfo['comments_html']['album'][0]; $fileinfo[$read]['filename']=$ThisFileInfo['filename']; $fileinfo[$read]['modified']=date ("YmdHis", filemtime($directory.'/'.$read)); if($debug==true) echo "<br />$read was last modified: " . date ("YmdHis", filemtime($directory.'/'.$read)); $fileinfo[$read]['path']=$directory.'/'.$read; if($debug==true)echo'<span style="margin-left: 10px;">path:'.$fileinfo[$read]['path'].' > fn: '.$fileinfo[$read]['filename'].'</span><br /><br />'; if($parent!=null) $fileinfo[$read]['from']=str_replace(array('./', '//', '/'), array('', '»', '»'), $directory); // was =$parent else $fileinfo[$read]['from']='root'; //testing this if($debug==true)echo'<br />'.$fileinfo[$read]['from'].'<br />'; //debug //echo$ThisFileInfo['filename'].'<br />'; } else{ //store filename $fileinfo[$fileinfo['count']]['path']=$directory.'/'.$read; $fileinfo[$fileinfo['count']]['fn']=$read; if($parent!=null) $fileinfo[$fileinfo['count']]['from']=str_replace(array('./', '//', '/'), array('', '»', '»'), $directory); $fileinfo[$fileinfo['count']]['modified']=date ("YmdHis", filemtime($directory.'/'.$read)); //$fileinfo[$fileinfo['count']]=date ("YmdHis", filemtime($directory.'/'.$read)); } //inc counter $fileinfo['count']=$fileinfo['count']+1; // had ++ and it didn't work } else ;//do nothing } //else, must be a folder (as determined above), recurse folder else{ //debug if($debug==true)echo '^^ DIR<br />'; //capture subfolders in case they are needed if($parent!='')$fileinfo['folders'].=$parent.'»'.$read.'|'; else $fileinfo['folders'].=$read.'|'; $fileinfo['folderpaths'].=$directory.'/|'; $fileinfo=recursiveGetSongs($directory.'/'.$read, $fileinfo, $useID3, $getID3, $parent.'/'.$read, $debug, $filtered); } } } closedir($dir); return $fileinfo; } ?> Quote Link to comment Share on other sites More sharing options...
j9sjam3 Posted April 4, 2011 Share Posted April 4, 2011 I mean, have an allowed folder array? So whoever only has access to certain folders. This is also better for security. Quote Link to comment Share on other sites More sharing options...
nickharambee Posted April 4, 2011 Author Share Posted April 4, 2011 Mmmh. I am not too clever with PHP (the script was written mostly by another). Would the allowed folder array just allow folders that have mp3s in? Because the folders that have MP3s in could be named anything (every user who logs in to the site gets a folder which is generated by their login), I couldn't include folders by name. The issue is that, because folders are generated on login, empty folders are getting added to the folder list array, and I only want them to show up once users have uploaded MP3 files to them.
