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);

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 want to delete images from public:// sub folder pro grammatically. i have paths like this below.
$path = 'http://localhost/Drupal/dbquery/sites/default/files/take_snap/20140713110549.jpg';
i want to delete like this,
$path = 'http://localhost/Drupal/dbquery/sites/default/files/take_snap/20140713110549.jpg';
$del = unlink($path);
but it doesn't delete image. i try to do this from menu call back function. how do i do that?.
In Drupal 7 you can use the file_delete to delete the file and its DB records as well.
these codes work. i just changed the path to relative path like below.
$path = 'sites/default/files/take_snap/20140713110549.jpg';
$del = unlink($path);
Now it deletes file from public sub folder.
i have a form that contains two file element with unique name. i want to reach each file element from Zend_File_Transfer_Adapter_Http(); how can i do that?
if i use
$apt = new Zend_File_Transfer_Adapter_Http();
.
.
$apt->receive();
two files have been uploaded. but i execute different queries for each file element.
for example
$smallPic = small pic name that i get from input smallPic
i execute
update products set smallPic = '$smallPic'
and for large pic
$largePic = large pic name that i get from input largePic
i execute
update products set largePic = '$largePic'
how can i reach each input file element with $apt ?
Here is some code I have used in the past to receive multiple files from a Zend_Form where many of the file upload fields were dynamic and not part of the form.
Since you know the names of the two file uploads, you can also say $apt->getFileInfo('my_file');
$apt = new Zend_File_Transfer_Adapter_Http();
$files = $apt->getFileInfo();
foreach($files as $file => $fileInfo) {
if ($apt->isUploaded($file)) {
if ($apt->isValid($file)) {
if ($apt->receive($file)) {
$info = $apt->getFileInfo($file);
$tmp = $info[$file]['tmp_name'];
$data = file_get_contents($tmp);
// here $tmp is the location of the uploaded file on the server
// var_dump($info); to see all the fields you can use
}
}
}
}
Hope that helps.
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.
