[SOLVED] Directory List Script

[redhat617]

I have a script on our website at: http://www.silverlakefire.com/minutes.php that looks in a certain directory and builds a page that lists all the files in said directory. The script works fine except as you can see on the page, I can't seem to get them in any sort order. I would like them to sort by filename in descending order. Does anyone have any ideas what I need to fix in my script. I have a copy of it below:

Thank You...

 

<?php

define("BASE_DIR", './data/minutes/');

$imgsrc="exts/";

?>

<?php

$dir=str_replace('..','',$_GET['dir']);

if(substr($dir,-1,1)!='/'&&$dir!='') $dir.='/';

 

function prevDir($dir) {

if (substr($dir, -1, 1) == '/')

$dir = substr($dir, 0, strlen($dir)-1);

if (($pos=strrpos($dir, '/')) !== false)

return substr($dir, 0, $pos+1);

else

return '';

Try the following:

 

foreach(sort(glob()) as $filename){
echo $filename."<br>";
}

 

See if that will echo out the filenames alphabetically.

 

glob() is much more useful than an opendir() and you can read up on it.

[redhat617]

I am very new to PHP, so not to sound dumb, but can you tell me what lines I replace using the suggested code?

 

Thank You

[redhat617]

I did get the glob() script to work. However it also show the directory path and the files are no longer hyperlinks.

 

Here is what it looks like: http://www.silverlakefire.com/newsnew.php

 

 

[JasonLewis]

To make it just show the filename you can use basename(). To link them just use HTML, along with the filename and path.

[redhat617]

I have tried to re-write the script using the glob() and basename() still with no results. The original script I posted works fine except I want to sort it in descending order. Any idea how to do that without a total re-write?

[BlueSkyIS]

if your items are in arrays, you can use rsort($array) for a reverse sort of the array, then loop over the rsort'ed array, displaying data.

[redhat617]

I have tried the rsort. Here is the syntax I used it:

rsort($files);

foreach($files as $key=>$val){
$ext=str_replace(".","",strrchr($key,"."));
echo "<tr class=\"row".($row%2)."\">\n";
echo "\t\t\t\t<td>";

if(file_exists($imgsrc.$ext.".gif"))
	echo "<img src=\"{$imgsrc}{$ext}.gif\" alt=\"{$ext}\" />";
else
	echo "<img src=\"{$imgsrc}unknown.gif\" alt=\"{$ext}\" />";

echo "</td>\n";
echo "\t\t\t\t<td><a target=_blank href=\"".BASE_DIR.$dir.$key."\">{$val}</a></td>\n";
echo "\t\t\t</tr>";
$row++;
}

echo "<tr class=\"title\">\n";
echo "\t\t\t</tr>\n";
echo "\t\t</table>\n";

 

When I do that, the output in the webpage is:

Array

Array

Array

 

Instead of the filename.

[BlueSkyIS]

it appears you are sorting an array of arrays, so you may need to echo the part of those sorted arrays that you want, e.g., $val['time']

[redhat617]

Still having problems with this.

[AndyB]

It appears as though you have resolved this. If so, click the topic SOLVED icon.

[redhat617]

No I still have not resolved this. I am back to the original problem.

 

I have tried the Glob function as suggested. I have also tried the Sort funtion but neither give me the required results.

[AndyB]

<?php
$x = glob("*.php");
sort($x);
for ($i=0;$i<count($x);$i++) {
echo $x[$i]. "<br/>";
}
?>

 

That works for me, installed in the target directory.  You can adjust to suit, including turning the file names into clickable links.

[redhat617]

Well I am almost there, and thanks to all for your help in getting me here. Now I just am struggling in getting the links to display right. When I use Andy B's code it works fine, when I try to get them hyperlinked it is different.

 

If i use the following code:

<center>
<?php
chdir('./data/news/');
$x = glob("*.*"); 
rsort($x);
for ($i=0;$i<count($x);$i++) {
echo "<p><a target=_blank href=\"/data/news/\"".$x.">$x</a></p>\n"; 	
#	echo $x[$i]. "<br/>";
}
?>

All I get on the page is ARRAY, ARRAY, ARRAY,....

 

If I use the code:

<center>
<?php
chdir('./data/news/');
$x = glob("*.*"); 
rsort($x);
for ($i=0;$i<count($x);$i++) {
echo "<p><a target=_blank href=\"/data/news/\"".$i.">$i</a></p>\n"; 	
#	echo $x[$i]. "<br/>";
}
?>

All i get is 0,1,2,3.....

 

Any suggestions?

 

Thank You

[trq]

Because $x is an array.

 

echo "<p><a target=\"_blank\" href=\"/data/news/{$x[$i]}\">{$x[$i]}</a></p>\n";

Thanks for all the help. SOLVED
