i am coding a simple doc managing script and need to get the file size and file type /file or folder/ in a table. somehow it doesn't work into the mention directory. please help if possible:

$path = "./documents"; $dh = dir($path); while( ($file=$dh->read()) ) if( $file=="." || $file=="..")continue; echo "<tr><td><a href='download.php?f=$file' title='Click to Open/Download'>$file</a></td>"; echo "<td>"; echo (is_file($file))? "<img src='file.jpg'/> FILE" : "<img src='folder.jpg'/> FOLDER "; echo "</td><td>" .filesize($file)."</td>"; echo "<td><input type='checkbox' name='delete[]'/></td></tr>";

it does actually has 2 errors - one the file size doesn't work for the location, if i change it to path to "." - everything is ok, but if i try to change to the folder where i need it /documents ...all goes bad, and secondly - it doesn't take the right icon file as well, same type of problem. thank you

Problem is, $file is only the filename without the directory prefix, so checking on it won't work. One way would be to have a variable with the absolute filename (say $realfile ). You'd then have to alter your code and use this variable for the file checks:

$path = "./documents"; $dh = dir($path); while(($file=$dh->read()) !== false) { if( $file=="." || $file=="..") continue; // have a new variable for the real filepath $realfile = $path . "/" . $file; echo "<tr><td><a href='download.php?f=$file' title='Click to Open/Download'>$file</a></td>"; echo "<td>"; echo (is_file($realfile))? "<img src='file.jpg'/> FILE" : "<img src='folder.jpg'/> FOLDER "; echo "</td><td>" .filesize($realfile)."</td>"; echo "<td><input type='checkbox' name='delete[]'/></td></tr>"; this is the green check sign on the left? right? i think it is now checked. thx. i am fighting with another 'small' prbm with the same code - trying to give the option to either DOWNLOAD the file (an href url ) or OPEN in case it is a DIRECTORY (folder) with php opendir() or similar. could you give me some ideas.

If anyone still encounters this error and the top answer didn't work for you. Then it must be because there is a special character in your filepath i.e. \r or \n

$f = str_replace(Array("\n", "\r", "\n\r"), '', $f);

This is a common problem for reading content on a file.
