php - Images won't be uploaded with the cakephp-upload behavoir -

i wan't build simple upload functionality inside cakephp 3.x application. have used cakephp-upload behavior. on moment can save needed data database, image won't uploaded. i've checked related articles here on stackoverflow cakephp 2.x , not version 3.x.

the view looks this:

<?php echo $this->form->create($form, ['type' => 'file', 'id' => 'form', 'class' => 'form-horizontal', 'url' => '/storages/form/content/' . $formid]); ?>  // other input fields  <?php echo $this->form->input('photo', ['type' => 'file']); ?> <?php echo $this->form->end(); ?> 

the function save photo related stuff database looks this:

// $array consists of data     [         'data||1' => 'data',         'photo' => [             'tmp_name' => '/applications/mamp/tmp/php/phphbvbqz',             'error' => (int) 0,             'name' => 'screen shot 2017-08-22 @ 14.26.17.png',             'type' => 'image/png',             'size' => (int) 163117         ] ]   private function addcontent($array) {         $form = $this->gethighestformid();          foreach ($array $field => $value) {             if ($value != null) {                 // create new entity                 $containercontent = $this->storagecontainercontent->newentity();                  // explode field name , container_block_element_id                 $explodedfield = explode("||", $field); // [0] field, [1] container_block_element_id                  // remove automatic generated _ character string , replace whitespace                 // $replacedname = str_replace("_", " ", $explodedfield[0]);                  // create array                 $data = [                     'user_id' => $this->auth->user('id'),                     'form_id' => $form->maxformid + 1,                     'storagecontainer_block_element_id' => $explodedfield[1],                     'identifier' => $explodedfield[0],                     'content' => $value                 ];                  // patch data                 $containercontent = $this->storagecontainercontent->patchentity($containercontent, $data);                  // safe value                 $this->storagecontainercontent->save($containercontent);             }         }     } 

finally, table class looks this:

class storagecontainercontenttable extends table {      /**      * initialize method      *      * @param array $config configuration table.      * @return void      */     public function initialize(array $config) {         parent::initialize($config);          $this->settable('storagecontainer_content');         $this->setprimarykey('id');          $this->addbehavior('josegonzalez/upload.upload', [             'photo' => [                 'fields' => [                     'dir' => 'photo_dir',                     'size' => 'photo_size',                     'type' => 'photo_type'                 ],                 'namecallback' => function ($data, $settings) {                     return strtolower($data['name']);                 },                 'transformer' =>  function ($table, $entity, $data, $field, $settings) {                     $extension = pathinfo($data['name'], pathinfo_extension);                      // store thumbnail in temporary file                     $tmp = tempnam(sys_get_temp_dir(), 'upload') . '.' . $extension;                      // use imagine library thing                     $size = new \imagine\image\box(40, 40);                     $mode = \imagine\image\imageinterface::thumbnail_inset;                     $imagine = new \imagine\gd\imagine();                      // save modified file our temp file                     $imagine->open($data['tmp_name'])                         ->thumbnail($size, $mode)                         ->save($tmp);                      // return original *and* thumbnail                     return [                         $data['tmp_name'] => $data['name'],                         $tmp => 'thumbnail-' . $data['name'],                     ];                 },                 'deletecallback' => function ($path, $entity, $field, $settings) {                     // when deleting entity, both original , thumbnail removed                     // when keepfilesondelete set false                     return [                         $path . $entity->{$field},                         $path . 'thumbnail-' . $entity->{$field}                     ];                 },                 'keepfilesondelete' => false             ]         ]);     } } 

you not build custom dataset , save that, there's nothing special need in saving process, that's why it's not in docs.

all need use configured name in form you're doing it, , patch entity request data without modifications, save , upload behavior rest, ie if $array raw request data, pass directly patchentity().
