HowTo: Use "Photowidget" by RoyTanck with G2

Hey there,

just thought I might share some stuff I came up with recently.

Photowidget is a nice flash app to display images on your webpage. In combination with the external image block you can actually use it with your gallery. That's how I got it to work:

/* settings */
$g2_url = 'www.mygallery.com';              // url to main.php
$thumb_size = 60;                           // thumbnail size in pixel
$images = array ( 'randomImage'   => 12,    // number of types of images
                  'recentImage'   => 0,
                  'viewedImage'   => 0,
                  'randomAlbum'   => 0,
                  'recentAlbum'   => 0,
                  'viewedAlbum'   => 0,
                  'dailyImage'    => 0,
                  'weeklyImage'   => 0,
                  'monthlyImage'  => 0,
                  'dailyAlbum'    => 0,
                  'weeklyAlbum'   => 0,
                  'monthlyAlbum'  => 0,
                  'specificItem'  => 0 );


while( list ( $type, $count ) = each ( $images ) ) {
  for($i = 0; $i < $count; $i++) {
    $image_list .= $type . '|';
  }
}
$image_list = substr($image_list, 0, -1);   // get rid of trailing '|'

/* create source code */
$code = file_get_contents('http://' . $g2_url . '/main.php?g2_view=imageblock.External&g2_blocks=' . $image_list . '&g2_show=none&g2_maxSize='. $thumb_size .'&
g2_itemFrame=none');

/* regex rules */
$regex_image = '=^(.*)(<img|<image)(.*)src\="?(\S+)"([^>]*)>(.*)$=msi';
$regex_url = '=^(.*)(<a)(.*)href\="?(\S+)"([^>]*)>(.*)$=msi';

/* start creating xml content */
$xml = '<images>'. "\r\n";

while (preg_match($regex_url, $code, $finds_url) && preg_match($regex_image, $code, $finds_image)) { 
  $xml .= '<image href="' . $finds_url[4] . '">' . $finds_image[4] . '</image>' . "\r\n" ;
  $code = $finds_url[1];
}

$xml .= '</images>';

/* write xml file */
$file = fopen("photowidget.xml", "w");
fwrite($file, $xml);
fclose($file);

This piece of code only creates the required photowidget.xml, using pathnames from the external image block. You still have to embed the actual flash file acording to the instructions on the widgets homepage.

Maybe someone finds it useful.

Cheers,
Felix

See it in action here.

That's what I forst wanted to do. I tried after you had mentioned your script a while ago - but somehow I didn't quite understand where to start
Might have a closer look again at some point
