Displaying HTML links to files in alphabetical order?

Copy linkTweet thisAlerts:
Apr 27.2012

Hello

I have a script that searches a folder on my server for pdf files then displays links to them on a web page in an unordered list. My questions is… is it possible to change the order that these files are displayed? Eg. alphabeticaly? I can’t work out how these files are being displayed by default… it doesn’t appear to be by modified date or alphabeticaly?

Any help greatly appreciated!

[code=php]<?php

$dom = new DOMDOcument ();
$ul = $dom->appendChild ($dom->createElement (‘ul’));

foreach (glob (‘*.pdf’) as $pdf) {
$li = $ul->appendChild ($dom->createElement (‘li’));
$a = $li->appendChild ($dom->createElement (‘a’));
$a->appendChild ($dom->createTextNode (str_replace (‘_’, ‘ ‘, pathinfo ($pdf, PATHINFO_FILENAME))));
$a->setAttribute (‘href’, $pdf);
$a->setAttribute (‘type’, ‘application/pdf’);
}

echo $dom->saveHTML();

?> [/code]

@BelrickApr 27.2012 — Hi

I have a script that allows users to download pdf files from my site.

To make it simple as possible i just dump a new file in and thats it.

How i make it work is simple.

I turn the file name into effectively an array.

orderdisplayed_Title_FileDescription.pdf

[code=php]

$x = explode("_",$filename);
$title = $x[1];
$description = $x[2];

[/code]

Order displayed is of course automatic as youve discovered. So just put A or B etc or 1 or 2 etc in the file name at start.

@whoauthorApr 28.2012 — OK... I'm rubbish at this and am having trouble. I've been trying this:
[code=php]<?php

$dom = new DOMDOcument ();
$ul = $dom->appendChild ($dom->createElement ('ul'));

$articles = glob('*.pdf') as $pdf);

rsort($articles);

foreach $articles) {
$li = $ul->appendChild ($dom->createElement ('li'));
$a = $li->appendChild ($dom->createElement ('a'));
$a->appendChild ($dom->createTextNode (str_replace ('_', ' ', pathinfo ($pdf, PATHINFO_FILENAME))));
$a->setAttribute ('href', $pdf);
$a->setAttribute ('type', 'application/pdf');
}

echo $dom->saveHTML();

?> [/code]

I'm getting this error: Parse error: syntax error, unexpected T_AS in.......

Any guidance would be so appreciated!
