[FIXED] CakePHP 3 Edit Upload

Issue

I was following this guide to do uploads on CakePHP 3. Using that guide, I select a file, and when I click upload, it moves that file to a designated folder inside the project, sets that folder as the path, and creates a newEntity in the database.

I'm trying to now get this same upload to be able to overwrite an existing entity (i.e. Edit instead of Add).

I duplicated the Upload function in the controller and View and modified them to be used as an Edit. However, upon attempting it, the Edit fails and I do not even get to an error message; the page just refreshes as if nothing has occurred.

The relevant table is Files, which has the following attributes:

• ID (primary key)
• link (the folder where the uploaded files are kept)
• name (the name of the file)
• created
• modified

This is my function in the controller:

public function edit($id = null)
    {
        $uploadData = $this->Files->get($id, [
            'contain' => []
        ]);
        if ($this->request->is('post')) {
            $data = $this->request->data;
            if(!empty($data['link']['name'])){
                $fileName = $data['link']['name'];
                $uploadPath = 'uploads/template/';
                $uploadFile = $uploadPath.$fileName;
                if(move_uploaded_file($data['link']['tmp_name'],$uploadFile)){
                    $uploadData = $this->Files->patchEntity($uploadData, $data);
                    $uploadData->name = $fileName;
                    $uploadData->link = $uploadPath;
                    if ($this->Files->save($uploadData)) {
                        $this->Flash->success(__('File has been uploaded and updated successfully.'));
                    }else{
                        $this->Flash->error(__('Unable to upload file, please try again.'));
                    }
                }else{
                    $this->Flash->error(__('Unable to upload file, please try again.'));
                }
            }else{
                $this->Flash->error(__('Please choose a file to upload.'));
            }
        }

        $files = $this->Files->find('all', ['order' => ['Files.created' => 'DESC']]);
        $filesRowNum = $files->count();
        $blanks = $this->Files->find('all', ['order' => ['Files.created' => 'DESC']])->first();
        $this->set(compact('blanks', 'uploadData', 'files', 'filesRowNum'));

    }

And this is my form:

<?php echo $this->Form->create($uploadData, ['type' => 'file']); ?>
<?php echo $this->Form->input('link', ['type' => 'file', 'class' => 'form-control', 'label' => 'Template Link' ]); ?><br>
<?php echo $this->Form->button(__('Upload File'), ['type'=>'submit', 'class' => 'btn btn-primary', 'style' => 'width:25%;']); ?>
<?php echo $this->Form->end(); ?>

In the controller, I've also attempted to replace if ($this->request->is('post')) { with ($this->request->is('patch', 'post', 'put')) {, similar to the Cake baked Edit pages.

If say I was to upload a blank Excel spreadsheet called Book 2.xlsx and wanted to overwrite the 4th data entry in the Files table, I would go to the URL localhost/project/files/edit/4, select the file and submit.

Upon doing so, no error messages appear, either Cake errors or flash errors, and in the CakePHP Request, I have the following array in POST:

link (array)
    name: Book2.xlsx
    type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
    tmp_name: C:\xampp\tmp\php3B10.tmp
    error: 0
    size: 7823

Solution

Change this:

if ($this->request->is('post')) {

To this:

if ($this->request->is('post') || $this->request->is('put')) {

Edit: As ndm pointed out, arrays work too:

 $this->request->is(['post', 'put', 'patch'])
