Codeigniter -> File Upload Path | Folder Create

am not sure what they are talking about by using the file_exist function since you need to check if its the directory ..

$folderName = $this->model->functionName()->tableName;$config['upload_path'] = "this/$folderName/";if(!is_dir($folderName)){   mkdir($folderName,0777);}

please note that :

1. i have added the permission to the folder so that you can upload files to it.
2. i have removed the else since its not useful here ( as @mischa noted )..

This is not correct:

if(!file_exists($folderName)){   mkdir($folderName);}else{   // Carry on with upload}

Nothing will be uploaded if the folder does not exist! You have to get rid of the else clause.

$path = "this/$folderName/";if(!file_exists($path)){   mkdir($path);}// Carry on with upload$config['upload_path'] = $path; 

Not quite sure what you mean by 'dictionary', but if you're asking about how to create a variable:

$folderName = $this->model->functionName()->tableName;$config['upload_path'] = "this/$folderName/";

To add/check the existence of a directory:

if(!file_exists($folderName)){   mkdir($folderName);}else{   // Carry on with upload}
