A string replace with array - plugins

Question

I am trying to create a simple image gallery for joomla 3. I have managed to get the code working. The way it works is that, it detects the string {dGalley}stories{/dGallery} from article. I have done this so far. It works but it only prints one image. Any suggestion? Thanks in advance.
<?php
defined('_JEXEC') or die;
class PlgContentgallery extends JPlugin
{
public function onContentPrepare($content, $article, $params, $limit){
preg_match_all('/{dGallery}(.*?){\/dGallery}/is', $article->text, $matches);
$i=0;
foreach ($matches[1] as $value)
{
$result = array();
$dir = '/home/juniorwe/public_html/images/'.$matches[1][$i];
$cdir = scandir($dir);
foreach ($cdir as $key => $value)
{
if (!in_array($value,array(".","..")))
{
if (is_dir($dir . DIRECTORY_SEPARATOR . $value))
{
$result[$value] = dirToArray($dir . DIRECTORY_SEPARATOR . $value);
}
else
{
$article->text = str_replace('{dGallery}'.$matches[1][$i].'{/dGallery}','<img src="../images/'.$matches[1][$i].'/'.$value.'"/>
', $article->text);
}
}
}
$i++;
}
}
}
Updated code. It works but a bit dirty solution:
<?php
defined('_JEXEC') or die;
class PlgContentgallery extends JPlugin
{
public function onContentPrepare($content, $article, $params, $limit)
{
$document = JFactory::getDocument();
$document->addScript(JURI::base(). "plugins/content/gallery/jquery.colorbox.js");
$document->addScript(JURI::base(). "plugins/content/gallery/colorboxCall.js");
$document->addStyleSheet(JURI::base(). "plugins/content/gallery/colorbox.css");
preg_match_all('/{dGallery}(.*?){\/dGallery}/is', $article->text, $matches);
$i=0;
foreach ($matches[1] as $value)
{
$result .= '';
$dir = '/home/juniorwe/public_html/images/'.$matches[1][$i];
$cdir = scandir($dir);
foreach ($cdir as $key => $value)
{
if (!in_array($value,array(".","..")))
{
if (is_dir($dir . DIRECTORY_SEPARATOR . $value))
{
$result[$value] = dirToArray($dir . DIRECTORY_SEPARATOR . $value);
}else{
$result .='<a class="group4" href="../images/'.$matches[1][$i].'/'.$value.'" title=""><img src="../images/'.$matches[1][$i].'/'.$value.'" class="gallery"/></a>';
}
}
}
$article->text = str_replace('{dGallery}'.$matches[1][$i].'{/dGallery}',$result, $article->text);
$i++;
}
}
}

Answer 1

You want something more like this
public function onContentPrepare($content, $article, $params, $limit)
{
preg_match_all('/{dGallery}(.*?){\/dGallery}/is', $article->text, $matches);
foreach ($matches[0] as $folder)
{
$result = array();
$dir = '/home/juniorwe/public_html/images/' . $folder; // You might want to get the stored value for image path instead of hard coding
if (is_dir($dir))
{
$cdir = JFilesystem::files($dir);
foreach ($cdir as $value)
{
$article->text = str_replace('{dGallery}' . $folder .'{/dGallery}','<img src="/images/' . $folder . '/' . $value. ' "/>', $article->text);
}
}
}
}
Is it that you are trying to get the images from the sub folders also?
