Create a Folder [SOLVED]

[ramjet]

Can someone tell me how to programatically create a folder - and also print a message to say its created - from an on_save callback.

//create realestate folder if it doesn't already exist
public function generateFolder()
{	
   if(!file_exists(TL_ROOT . '/realestate'))
   {

  //createFolder
  //inform that this folder has been created... messages????????
						
  }

}

TAA...ta in advance :D

There is a File, Files and Dir one of these classes has the function to create folders. See http://api.contao.org

It actually should be Folder class I think, but I just can't make it happen.
I can't see why this doesn't work, but it doesn't! Theres no errors, just no result.

From dca/tl_realestate.php

		'onsubmit_callback' => array
		(
			array('tl_realestate', 'generateFolder')
		)

class tl_realestate extends Backend
{

	//generate a new folder based on street/name AND id initially and each time the street/name is changed
	public function generateFolder(DataContainer $dc)
	{
	$foldername = 'realestate/' . $dc->activeRecord->accomm_street .'_id_'. $dc->id;
	$folder = new Folder($foldername);
	
	//inform that this folder has been created... messages????????
	}

....

Do I need to import something since it extends backend ?

[grapio]

ehm. The code for creating the folder looks alright. It might be that there is something wrong with you callback function. Or that foldername is not correct.

i give up for the evening (i've been at this for hours!)
Thanks Grapio ( and Tru).... I've tried it on an onload_callback and also just trying to create a Folder called realestate.
I've also tried importing the Files class, the Folder class.

	
public function generateFolder(DataContainer $dc)
	{
	$this->import('Files');
	$strDirectory = 'realestate';
	$arse = new Folder($strDirectory);
	}

The Registration Module does it this simply, but not through a callback, and the class extends Module

			$this->import('Files');
			new Folder($this->reg_homeDir . '/' . $strUserDir);

Anyway, to tired now to think... cheers

class tl_realestate extends Backend
{

	//generate a new folder based on street/name AND id initially and each time the street/name is changed
	public function generateFolder(DataContainer $dc)
	{
	$foldername = 'realestate/' . $dc->activeRecord->accomm_street .'_id_'. $dc->id;
	$folder = new Folder($foldername);
	}

....

please note that $foldername should start with $GLOBALS['TL_CONFIG']['uploadPath'] (e.g. tl_files) if you want to create the folder into the "File Manager"

so the above code should be

$foldername = $GLOBALS['TL_CONFIG']['uploadPath'].'/'.'realestate/' . $dc->activeRecord->accomm_street .'_id_'. $dc->id;

hope this helps

Thanks ga.n, perfect.
Importing 'Files' was not necessary, and it works fine in on_submit callback. :D

Also for anyone interested it will create all the levels needed - so to create folder3 in folder2 in folder1 in tl_files the first two don't need to already exist.

$foldername = $GLOBALS['TL_CONFIG']['uploadPath'].'/folder1/folder2/folder3';

Any idea how a message is printed back to the screen "The Folder xxx has been created" ?

This is also true for a file. If you try to create it with new File() then it also auto-creates all the intermediate folders. If the file exists, it just opens it, otherwise, it creates not only the folder structure but also the file itself.

Regarding

Any idea how a message is printed back to the screen "The Folder xxx has been created" ?

That is done bythe use of

$_SESSION['TL_CONFIRM'][]

So my complete onsubmit_callback function is

	public function generateFolder(DataContainer $dc)
	{
	$foldername = $GLOBALS['TL_CONFIG']['uploadPath'].'/realestate/' . $dc->activeRecord->accomm_street .'_id_'. $dc->id;

			//create the folder and inform  ONLY if it doesn't already exist	
			if (!file_exists(TL_ROOT . '/'. $foldername))
			{
			$folder = new Folder($foldername);
			//inform that this folder has been created...
			$_SESSION['TL_CONFIRM'][] = $GLOBALS['TL_LANG']['tl_realestate']['folder_created'] . $foldername;	
			}

	}

which creates a new folder if it doesn't exist already, and informs of this at the top of the page in green with a little tick icon.

A folder to upload images to has been created in the File Manager: tl_files/realestate/Bishop St_id_22
