The cakephp documentation is a bit poor according the File api and I would like to use it to copy one file to another directory and if the directory does not exist to create it.
Thanks!
You can do something like this:
$file = new File('your_file.ext');
if ($file->exists()) {
$dir = new Folder('folder_inside_webroot', true);
$file->copy($dir->path . DS . $file->name);
}
API about these classes:
Folder;
File;
I hope it helps.

$user= $this->Users->newEntity();
I want to create a folder for every registered user
example if new user input michael
how to achieve this and will create a directory /img/users/michael/
$dir = new Folder(WWW_ROOT.'img'.DS.'users'.$user->username);
$path_data = $dir->create($dir);
Error: Cannot use object of type Cake\Filesystem\Folder as array
Create directory PATH will in in create() method
$dir = new Folder(WWW_ROOT.'img'.DS.'users'.$user->username);
$path_data = $dir->create($dir);
should be
$dir = new Folder();
$path_data = $dir->create(WWW_ROOT.'img'.DS.'users'.$user->username);
Details Here
Update
There is a directory separator missing. it should like
$dir = new Folder();
$path_data = $dir->create(WWW_ROOT.'img'.DS.'users'.DS.$user->username);
Thanks #ndm
I am just trying to check if an image exists or not, I can do it by using PHP. For example:-
$file = WWW_ROOT .'uploads' . DS . 'employee' . DS .'_'.check.jpg;
$file_exists = file_exists($file);
It's working fine for me. But I have tried also tried using elementExists like this:-
if($this->elementExists("../".$employees->front_image))
{
echo $this->Html->image("../".$employees->front_image); // image output fine without condition.
}
// Here $employees->front_image = uploads/employee/employeename.jpg
This check is not working. How can I do this in CakePHP?
CakePHP is written in PHP, so if you already have a simple solution like file_exists() use that. So you can write something like this:-
if (file_exists(WWW_ROOT . $employees->front_image)):
echo $this->Html->image('../' . $employees->front_image);
endif;
elementExists() is intended for checking that a View element exists, not if files exist in the webroot, so should not be used like you are trying. It does do a file_exists() check, but this scans all available View element paths only.
I think this works in Cake 3 (you should do this in afterFind method IMO):
// Create a new file with 0644 permissions
$file = new File('/path/to/file.php', true, 0644);
if ($file->exists()) {
//do something
}
$file->close();
Your way is checking whether view element exists or not.
This worked for me:
Q: How to check if image exists on remote url or not?
Explanation:
$rfile will take url
$check will open the file with read rights
If file exists then it will print "File exists" else "Doesn't exists".
code:
<?php
// Remote file url
$rFile = 'https://www.example.com/files/test.pdf';
// Open the file
$check = #fopen($rFile, 'r');
// Check if the file exists
if(!$check){
echo 'File does not exist';
}else{
echo 'File exists';
}
?>
I have a directory with images and I show to the user,the user can rename a image, I have the file with
$images = File::files('img');
$image = $images[0];
But I don't know how rename an image.
Thanks
You can retrieve it first from the input. and move it using file name you define.
Your image will using the file name you specify.
$picture= $request->file('image');
$fileName = 'what the image you want to call';
$picture->move('image/foo', $fileName);
Brother, This is work for me. And I hope, It'll serve your purpose
$destinationPath = "uploadedImages";
$newName = md5_file($request->file('file_name')->getRealPath());
$guessFileExtension = $request->file('file_name')->guessExtension();
$file = $request->file('file_name')->move($destinationPath, $newName.'.'.$guessFileExtension);
Is there any instance to return bool? e.g. $folder->exists() => bool
$path = WEBROOT_DIR .'/files/'. $folder_name;
$folder = new Folder('../'.$path);
//DOESN'T WORK
debug($folder->exists());
//I can do it in this way
//returns bool
debug(file_exists($folder->path));
I want to check if directory exists delete it. but I want to use specifically cake method to check if folder exists
Try this:
$path = 'files' . DS . $folder_name;
$folder = new Folder($path);
if (!is_null($folder->path)) {
$folder->delete();
}
Cakephp Folder class does not have method exists like File class has.
You could check if the folder exists with standard php and then delete it.
if (file_exists('path/to/directory')) {
rmdir('path/to/directory', 777, true);
}
Basically it checks if the folder exists with the file_exists function and if the file does not exist then it will use rmdir function to create the folder.
Though I think you could use cakephp like this. This will delete the folder even if the folder does not exist because the Folder constructor will create the folder if the folder does not exist.
$folder = new Folder('path/to/directory', true, 777);
$folder->delete();
I uploaded xml file in my cakephp in img/files directory
app->webroot->files->Myfile.xml
and I want to call it from my controller like this
$file = "/files/Myfile.xml";
I am not sure is this the correct path from the controller ot not
of course controller is in app->controllers->my_controller
thanks
Use one of the CakePHP Core Configuration Constants.
WWW_ROOT for example:
$file = WWW_ROOT . "files/MyFiles.xml";
