Upload a file from custom component folder when installing the component

Question

I know how to upload file given from jform if a component is already installed. But how to upload a file from my admin/assets/ folder of my component when installing the component? In my script.php I try the following code:

jimport('joomla.filesystem.folder');
jimport('joomla.filesystem.file');
...
public function install($parent)
{
   // creating a folder
   $path = JPATH_ADMINISTRATOR . DIRECTORY_SEPARATOR . "templates" . DIRECTORY_SEPARATOR . "isis" . DIRECTORY_SEPARATOR . "html" . DIRECTORY_SEPARATOR . "com_content" . DIRECTORY_SEPARATOR . "article";
   $mode = 0755;
   JFolder::create($path, $mode);

   // uploading a file
   $file = JPATH_COMPONENT_ADMINISTRATOR . DIRECTORY_SEPARATOR . "assets" . DIRECTORY_SEPARATOR . "edit.php";
   $filename = JFile::makeSafe($file['name']);
   $src = $file['tmp_name'];
   $dest = JPATH_ADMINISTRATOR . DIRECTORY_SEPARATOR . "templates" . DIRECTORY_SEPARATOR . "isis" . DIRECTORY_SEPARATOR . "html" . DIRECTORY_SEPARATOR . "com_content" . DIRECTORY_SEPARATOR . "article" . DIRECTORY_SEPARATOR . $filename;
   JFile::upload($src, $dest);
}

The folder is being created successfully but the file is not being uploading to the folder and I get the can't move error

Answer 1

I think you have got muddle up here. When you install an extension, you already uploading a zip file. So once Joomla had processed this zip, the files are already on the server. You cannot "upload" a file from one directory to another. You need to "move" or "copy" it.

You the code you'll need to use will either be:

JFile::move($src, $dest);

or:

JFile::copy($src, $dest);

And as @Nagarjun already said, you need to put this code in the postflight function rather than the install function. Ig you use the install function, the $src file that you define may not yet exist ;)

Hope this helps

Do your file movement tasks in postflight function of your script.php file

function postflight($type, $parent) 
{
  // do it here
  JFile::move($src, $dest);
}

This function get called after copying files from your package, databases gets updated etc.
