Need a PHP doctor...
Hi folks ;)
I need to preload all my images for a website, in purpose to speed up it, and try this :
<txp:php>
$rep = hu.'img';
if ($dir = opendir($rep)) {
while (false !== ($file = readdir($dir))) {
echo '<style type="text/css">';
echo '#preloadedImages {';
echo 'width: 0px;';
echo 'height: 0px;';
echo 'display: inline;';
echo 'background-image: url('.$rep.$file.');';
}
}
closedir($dir);
</txp:php>
This PHP rule come from PHP.net reference website… but it’s don’t work at all.
So do somebody know a method to list all images within a directory?
Thanks lot by advance for your helpfull answer.
Best regards,

that won’t work as it takes your site URL (that’s the hu bit) and tries to use it as a file path. Try this instead…
<txp:php>
global $prefs;
$rep = $prefs['path_to_site'].DS.'images'; # change to point to your images directory
if ($dir = opendir($rep))
{
while (false !== ($file = readdir($dir)))
{
echo '<style type="text/css">';
echo '#preloadedImages {';
echo 'width: 0px;';
echo 'height: 0px;';
echo 'display: inline;';
echo 'background-image: url('.$rep.$file.');';
}
}
closedir($dir);
</txp:php>It’s untested and very late here so apologies if it doesn’t quite make the grade.

Patrick,
<txp:php>
echo '<style type="text/css">';
global $prefs;
$rep = $prefs['path_to_site'].DS.'img';
$i = 0;
if ($dir = opendir($rep)) {
while (false !== ($file = readdir($dir))) {
if($file != "." && $file != "..") {
$i = $i+1;
echo '#preloadedImages .a'.$i.' {';
echo 'width: 0px;';
echo 'height: 0px;';
echo 'display: inline;';
echo 'background-image: url('.$rep.'/'.$file.');';
echo '}';
}
}
}
closedir($dir);
echo '</style>';
</txp:php>Fixed the code. Also made it to strip those dot out of it, as they are caused by filesystem.
PS. made sure that the directory is img and correct ;)
Cheers!

Re: Need a PHP doctor...
Are you sure you want all your images to preload ? The css alone is making the page heavier, let alone the impact it has on the brandwith to transfer all those images. But it depends of course on the number of images you uploaded and the traffic you have.
Oh, and currently, it will preload the original image and the thumbnail.
Oh, wait a second, it won’t preload anything because you still need to write all those links in the #preloadedImages span.

Re: Need a PHP doctor...
Jukka, your first code works fine. I’ve got this :
#preloadedImages .a1 {width: 0px;height: 0px;display: inline;background-image: url(/var/www/vhosts/my-site.com/httpdocs/img/image.png);} (...)
Tks lot! Great!
It’s a pitty we can’t put all this styles line into a css style sheets file.
Cheers, mate!

You could create a file, “styles.php,” with the following:
<?php
header('content-type: text/css; charset=utf-8');
//Jukka's code
?>
html {
background: #fff;
}
/*rest of css*/Last edited by jm (2008-01-06 20:18:37)

Re: Need a PHP doctor...
Or you could use ako_cssparse
And place the code inside Textpatterns CSS-mechanism ;). Althought it works absolutely same way as jm’s suggestion, only difference is that then it’s stored inside database, and it can be edited via Textpattern.
