[Resolved] Display File names UNLESS File name is?

[middleman666]

hey,

got this code that echos the file names in a directory and make them into a link for that file.

while($file = $curdir->read()) { 	
	echo "<a href='$PHP_SELF?file=$file&dir=".$mydir."'>$file</a><BR>\n";
		}		
	echo "";
}

What i want to know is, from this how can I stop certain files being listed?

is it simply a case of an If function?

[middleman666]

ok i used:

if ( $file == "FILENAME" ) { 

echo "";

}
 else {
}

What do i use insted of echo if i simply dont want the file to appear? is it unlink() or something?

[middleman666]

ok, why wouldn't this work:

if ( $file == "FILENAME" ) { 
$file == "";
}

If you don't want to do anything in the case of a certain filename, then don't do anything:

if ($file != $forbidden_file) {
    echo '<a href="page.php">' . $file . '</a>';
}

[middleman666]

ok, that just reloads the page... thanks anyway but what i want is for it simply not to print out on the screen..

heres the whole script: (just for the record, this is an edited version of bit of script i have come across so not all the work is mine)

	ob_start(); 

if ($dir) 
{ 
	$mydir = $dir;
} else $mydir = ".";

$curdir=dir($mydir);

if($writefile) 
{
	$fd=fopen($mydir."/".$file, "w");
	fwrite($fd, stripslashes($text));
	fclose($fd);

} 
elseif($file) 
{

$fp=fopen($mydir."/".$file, "r"); // $mydir$myfile
while(!feof($fp)) {
	$con .= fgets($fp, 4096);
	}
fclose($fp);

echo "	<FORM ACTION='$PHP_SELF?METHOD='post'>\n
	<input type=hidden name=writefile value=$file>\n
	<input type=hidden name=file value=$file>\n
	<input type=hidden name=dir value=$mydir>\n
	<TEXTAREA ROWS='20' COLS='120' NAME='text'>\n";
echo $con;
echo "	</TEXTAREA><BR>\n
	<input type='submit' value='Save'> <input type='button' onClick='history.go(-1)' value='Cancel'>\n</form>\n";

} 
else 
{
	while($file = $curdir->read()) { 	
		// originally was $curdir->read()

if ( $file == "." ) { 
echo "DONOTEDIT";
}
if ( $file == ".." ) { 
echo "DONOTEDIT";
}
if ( $file == "edit.php" ) { 
echo "DONOTEDIT";
}
if ( $file == "index.php" ) { 
echo "DONOTEDIT";
}
 else {
}

	echo "<a href='$PHP_SELF?&file=$file&dir=".$mydir."'>$file</a><BR>\n";
	}		
echo "";
} 

ob_end_flush();

ok, that just reloads the page

while($file = $curdir->read())
{
    if($file=='Forbidden.ext') continue;

echo "<a href='$PHP_SELF?file=$file&dir=".$mydir."'>$file</a><BR>\n";
}

In the context of your more complete code:

while($file = $curdir->read()) {     

    if (is_unlistable($file))
        continue;
    echo "<a href='$PHP_SELF?&file=$file&dir=".$mydir."'>$file</a><BR>\n"; 
}

// And, somewhere....
function is_unlistable($file)
{
    $unlistable_files = array('.', '..', 'edit.php', 'index.php');
   return in_array($file, $unlistable_files);
}

I'm going to take a wild punt on this and guess that middleman666 didn't think to replace "page.php".

Going out on a limb with that guess, aren't you, W.P.? 🙂

If he hadn't lost interest, I was going to suggest something like this:

$do_not_edit_arr = array('.', '..', 'edit.php', 'index.php');
$do_not_show_arr = array('dont_show_me.txt', 'dont_show_me_either.txt');
while (($file = $curdir->read()) !== false) {      

    if (in_array($file, $do_not_edit_arr)) {  

        echo 'DONOTEDIT' . '<br />';
        continue; 
    } 
    if (!in_array($file, $do_not_show_arr)) { 
        echo '<a href="' . $_SERVER['PHP_SELF'] . 
             '?file=' . $file . '&dir=' . $mydir . '">' . 
             $file . '</a><BR>' . "\n"; 
    }         

}

We read what he wanted to do slightly differently, but the solutions are pretty close.

[middleman666]

sorry people, had to go away, but thanks for the suggestions, i will try them soon.

I always just got:

<?php
if ($handle = opendir($directory)) { 
while (false !== ($file = readdir($handle))) { 
if($file === "whatever.file" || $file === "whatever.file"){
echo ""; // displays nothing to the browser
}else{
echo $file; 
}
} 
closedir($handle); 
} 
?>

[middleman666]

used the one from weedpacket, works a charm! thanks people.

while($file = $curdir->read()) 
{ 
    if($file=='Forbidden.ext') continue; 

echo "<a href='$PHP_SELF?file=$file&dir=".$mydir."'>$file</a><BR>\n"; 
}
