Create a Folder [SOLVED]

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

Code:

---

//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

Code:

---

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

---

Code:

---

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 ?

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.

Code:

---

       
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

Code:

---

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

---

Anyway, to tired now to think... cheers

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

Code:

---

$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.

Code:

---

$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.

That is done bythe use of

Quote:

---

$_SESSION['TL_CONFIRM'][]

---

So my complete onsubmit_callback function is

Code:

---

        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.
