E' possibile modificare questo file..?

[enzo75]

Ciao a tutti ho un quesito da chiedervi..

ho un file che è parte di joomla che ha la funzione di visualizzare un numero dichiarato di immagini scelte a caso da una tabella del database..

questo è il codice:

<?php


// no direct access
defined( '_VALID_MOS' ) or die( 'Restricted access' );

// language-specific stuff
define ('_CLICK_OPEN_IMAGE','Guarda la galleria');
define ('_CLICK_OPEN_ALBUM','');

// Get parameters
$moduleclass_sfx = $params->get( 'moduleclass_sfx' );
$pretext         = $params->get( 'pretext' );
$size            = $params->get( 'size' );
$width           = $params->get( 'width' );
$count           = $params->get( 'count' );
$linkimage       = $params->get( 'linkimage' );
$border          = $params->get( 'border' );
$showtitle       = $params->get( 'showtitle' );
$showalbum       = $params->get( 'showalbum' );
$showauthor      = $params->get( 'showauthor' );
$showhits        = $params->get( 'showhits' );
$showdate        = $params->get( 'showdate' );
$albumlabel      = $params->get( 'albumlabel' );
$authorlabel     = $params->get( 'authorlabel' );
$hitslabel       = $params->get( 'hitslabel' );
$datelabel       = $params->get( 'datelabel' );
$orientation     = $params->get( 'orientation' );
$exclusions      = $params->get( 'exclusions' );
$approved        = $params->get( 'approved' );

// Format the exclusions as a part of the DB query
if ($exclusions)
{
    $exclusions = str_replace(" ","",$exclusions);
    while (substr($exclusions,0,1) == ",")
        $exclusions = substr($exclusions,1,strlen($exclusions)-1);
    while (substr($exclusions,strlen($exclusions)-1) == ",")
        $exclusions = substr($exclusions,0,strlen($exclusions)-1);
    $exclusions = str_replace( ",", ") AND (catid != ","AND (catid != ".$exclusions.")");
}

// Approved only?
if ($approved)
    $approved = "AND approved";

// Query every published record in the image table
$database->setQuery("SELECT * FROM #__ponygallery WHERE published $approved $exclusions");
$images = $database->loadObjectList();

// How many images are there?
$totalimages = count($images);
$imagesused = "~";

// We need to use a table for this to work
$content = "<table width='100%'>\n<tr>\n";

// Display the random image
if ($width)
    $width = "width='$width'";

// Produce as many images as requested
for ($i=0; $i<$count; $i++)
{
    // Select one at random
    do
        $selection = $images[rand(1,$totalimages-1)];
    while (stripos($imagesused,"~".$selection->id."~"));
    $imagesused .= $selection->id."~";

    if ( $size == "thumb" )
    {
        $imgsrc = "



[img]".$GLOBALS[[/img]imgthumbname."' border=".$border." $width />\n";
    }
    else
    {
        $imgsrc = "[img]".$GLOBALS[[/img]imgfilename."'  border=".$border." $width />\n";
    }

    // See if we need to make the image clickable
    if ( $linkimage )
        $content .= "<td>[url='".$GLOBALS[']id."' title='"._CLICK_OPEN_IMAGE."'>".$imgsrc."[/url]";
    else
        $content .= "<td>$imgsrc";

    // See if we need to add any text
    if ( $showalbum )
    {
        $database->setQuery( "SELECT name FROM #__ponygallery_catg WHERE cid=$selection->catid" );
        $album = $database->loadResult();
        if ( $linkimage ) $album = "[url='".$GLOBALS[']catid."' title="._CLICK_OPEN_ALBUM.">".$album."[/url]";
        $content .= "
".$albumlabel.$album."\n";
    }
    if ( $showtitle  and $selection->imgtitle != '' )   $content .= "
".$selection->imgtitle."\n";
    if ( $showauthor and $selection->imgauthor != '' )
    {
        // see if Community Builder is installed
        if (file_exists($GLOBALS['mosConfig_absolute_path']."/components/com_comprofiler"))
        {
            $database->setQuery("SELECT * FROM #__users WHERE username='$selection->owner'");
            $database->loadObject($user);
            $content .= "
".$authorlabel."[url='".$GLOBALS[']id'>".$selection->imgauthor."[/url]\n";
        }
        else
            $content .= "
".$authorlabel.$selection->imgauthor."\n";
    }
    if ( $showdate   and $selection->imgdate != '' )    $content .= "
".$datelabel.date($showdate,$selection->imgdate)."\n";
    if ( $showhits   and $selection->imgcounter != '' ) $content .= "
".$hitslabel.$selection->imgcounter."\n";

    if (($i < ($count-1)) && ($orientation == "vertical"))
        $content .= "<hr></td>\n</tr>\n<tr>\n";
    else
        $content .= "</td>\n";
}

$content .= "</tr></table>";

// Display any pretext specified
if ($pretext)
    $content = $pretext.$content;

?>

La mia domanda è:

sarebbe difficile modificarlo in modo tale che anzichè visualizzare un certo numero di immagini a caso, vengano visualizzate tutte le immagni presenti nella tabella e basta??

sono un pecorone in php e quindi non riesco a capire se è possibile farlo??

un grazie a chi mi aiuta!!!
