code review request
A couple of days ago, I was dismayed to find my ~/public_html directory
choked with junk files. I wanted a micro file manager to be able to
parse the files and directories quickly and it seems like php is the
answer.
I found a public domain script on www.phptoys.com called
microFileManager.php that I based the following code. The original code
used tables. The code below uses a style sheet and presents the
directory listing in column 1 and the selected file content in column 2
in a basic menu/content 2 column format.
Sample style sheet provided.
I'm new to php and would appreciate feedback on this script. Layout,
function calls, error handling - whatever. Perhaps there are php classes
or functions that can do this better.
The micro file manager requirements are...
o create a well written php script
o not to exceed 100 lines of code
o wrapping at column 80 - personal preference - posting to
newsgroup would make this requirement difficult at best -
so perhaps this should read - readable code.
o directory listings displayed on left column
o selecting item in listing displays item in right column
o two files only, the script and the stylesheet. No extra
gifs, functions, features.
o no tables
CODE:
<?php
function showHeader($path) {
print "<div id='Header'>";
print "Path: $path";
print "</div>";
}
function showMenu($path) {
if ($handle = opendir($path))
{
print "<div id='Menu'>";
print "<h2>Menu</h2>";
$up = substr($path, 0, (strrpos(dirname($path."/."),"/")));
print "<a href='".$_SERVER['PHP_SELF']."?path=$up'>Up one level</
a>";
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
$fName = $file;
$file = $path.'/'.$file;
if(is_file($file)) {
print "<a href=";
print "'".$_SERVER['PHP_SELF']."?path=
$path&file=$fName'";
print "=>$fName</a>";
} elseif (is_dir($file)) {
print "<a href=";
print "'".$_SERVER['PHP_SELF']."?path=
$file'>$fName</a>";
}
}
print "<br>";
}
print "</div>";
closedir($handle);
}
}
function showContent($path, $fn){
print "<div id='Content'>";
print "<h2>$fn</h2>";
$imageext = array(jpg, jpeg, JPEG, JPG, gif, png);
$textext = array(txt, cfg, sql, css, plugin);
$path_parts = pathinfo($fn);
if (in_array($path_parts['extension'], $imageext, true)) {
echo '<img src="' . $path . "/" . $fn . '">';
} elseif (in_array($path_parts['extension'], $textext, true)) {
echo '<pre>';
include("$path/$fn");
echo '</pre>';
} else {
include("$path/$fn");
}
print "</div>";
}
if (isset($_POST['submitBtn'])){
$actpath = isset($_POST['path']) ? $_POST['path'] : '.';
} else {
$actpath = isset($_GET['path']) ? $_GET['path'] : '.';
}
if (isset ($_GET['file']) )
{
$filename = $_GET['file'];
}
showHeader($actpath);
showMenu($actpath);
if (isset($filename)){
showContent($actpath, $filename);
}
?>
