Create new folder in 'images' with every new article

Question

I need to extend standard Joomla article options. I want to create new folder for article's images in 'images/news/' folder. The name for every new folder will be taken from article's alias. I'm have knowledge in Javascript, but have no idea how can I do this with PHP and wich files I need edit for this. My website works on Joomla 2.5 and at this moment I can't update it. So please keep in mind this moment.

Answer 1

I have no knowledge in Joomla. But this is the php command for creating a Folder:

 $dirPath = 'images/news/'.$alias;
 $result = mkdir($dirPath);

Ok like I said, i don't really know joomla. But it doesn't look that hard: https://docs.joomla.org/J2.5:Creating_a_content_plugin So i will try to give you a start. But if there is an answer from somebody who is skilled in Joomla i would listen to them =)

Basically you Need 2 Files for your Content plugin. A php File "myContentPlugin.php" which will look like this:

<?php

 defined('_JEXEC') or die();

jimport('joomla.plugin.plugin');


class plgMyComponent extends JPlugin
{
 public function __construct($subject, $config)
 { parent::__construct($subject, $config);
 }

 function onContentBeforeSave($context, &$article, $isNew)
 { global $mainframe;


 $dirPath = 'images/news/'.$articel->alias;
 $result = mkdir($dirPath);

 return true;
 }
}

and an XML file "myContentPlugin.xml" which will look like this:

 <?xml version="1.0" encoding="utf-8"?>
  <extension version="1.7" type="plugin" group="content">
    <name>myContentPlugin</name>

    <files>
            <filename plugin="myContentPlugin">myContentPlugin.php</filename>
    </files>

Answer 2

So, here is complete solution:

Add custom field type checkbox to article's backend (you can find many manuals over the inernet, so I'll be brief), for example 'create_folder';

<fieldset name="image_folder" label="Image folder">
    <field name="create_folder"
        type="checkbox"
        label="Create automatically"
        value="1"
        default="0"
        filter="intval"
    />
</fieldset>

Create plugin folder with .xml and .php files of your plugin (more info here: https://docs.joomla.org/J2.5:Creating_a_Plugin_for_Joomla )

This is code of my .php file:

<?php

defined('_JEXEC') or die;

class plgContentImgDir extends JPlugin
{
        public function onContentAfterSave($context,&$article){ 
        if($context=='com_content.article'){     
                $folder_name=substr($article->alias,0,30);
                $destination=JPATH_SITE.'/'."images/news";
                if(!file_exists($destination.$folder_name)){       
                    JFolder::create($destination.'/'.$folder_name,0755);
                }
        }
    }
}

?>

After you install your plugin, you'll get additional option in your article settings. If checkbox checked the new folder will be create in 'images' directory.
