Yii2 FileInput - File not saved into the server

Question

i am using Yii2 and Kartik's FileInput extension. and I am having issues with it saving to the directory. I am using the yii-advanced template, and generate the CRUD codes using gii. Currently editing it as I go.

When I save it it refused to save and show the "Please upload a file" message.

Files that will be saved with be .doc and .pdf mostly.

If I set the 'skipOnEmpty = True' in the model, it will save the form but not the file.

Datatype on my mysql table is set to VARCHAR because I want to save its path only.

I followed this guide - http://webtips.krajee.com/upload-file-yii-2-using-fileinput-widget/

Here is my model;

<?php

namespace app\models;

use Yii;

class FormMovement extends \yii\db\ActiveRecord
{

    public static function tableName()
    {
        return 'form_movement';
    }

    public function rules()
    {
        return [
            [['fm_date_received', 'fm_form_name', 'fm_from', 'fm_ptj'], 'required'],
            [['form_id'], 'integer'],
            [['fm_date_received', 'fm_date_action1', 'fm_date_action2'], 'safe'],
            [['fm_form_name', 'fm_note'], 'string', 'max' => 500],
            [['fm_from', 'fm_ptj', 'fm_action1', 'fm_action2'], 'string', 'max' => 100],
            [['fm_upload'], 'file', 'skipOnEmpty' => false, 'extensions'=>'jpg,pdf,png,doc,docx,xls,xlsx'],
        ];
    }

}

Then here is my controller(i included only the upload function, but it is the rest with the generated codes(CRUD actions),

<?php

namespace frontend\controllers;

use Yii;
use app\models\FormMovement;
use app\models\SearchFormMovement;
//use app\models\FormType;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
use yii\web\UploadedFile;

class FormMovementController extends Controller
{
public function actionUpload()
{
    $model = new FormMovement;
    if ($model->load(Yii::$app->request->post())) {
        $file = UploadedFile::getInstance($model, 'fm_upload');

        // store the source file name
        $model->fm_upload = $file->name;
        $ext = end((explode(".", $file->name)));

        $model->fm_upload = Yii::$app->security->generateRandomString().".{$ext}";

        $path = Yii::$app->params['uploadPath'] . $model->fm_upload;;

        if($model->save()){
            $file->saveAs($path);
            return $this->redirect(['view', 'id'=>$model->_id]);
        } else {
            // error in saving model
        }
    }
    return $this->render('create', [
        'model'=>$model,
    ]);
}
}

and this is my view, also the same like Controller. Codes are only the upload part.

<?php

use yii\helpers\Html;
use kartik\date\DatePicker;
//use app\models\FormMovement;
use app\models\FormType;
use yii\bootstrap\ActiveField;
use kartik\form\ActiveForm;
use kartik\file\FileInput;

/* @var $this yii\web\View */
/* @var $model app\models\FormMovement */
/* @var $form yii\widgets\ActiveForm */
?>

<div class="form-movement-form">

    <?php $form = ActiveForm::begin([![\[][1]][1]
        'type' => ActiveForm::TYPE_HORIZONTAL,
        'formConfig' => ['labelSpan' => 3, 'deviceSize' => ActiveForm::SIZE_SMALL], 
        'options' => ['enctype' => 'multipart/form-data']
    ]); ?>
<div class="form-group kv-fieldset-inline">
        <?= Html::activeLabel($model, 'fm_upload', [
                'label'=>'MUAT NAIK FAIL',
                'class'=>'col-sm-1 control-label'
            ]) ?>

        <div class="col-sm-8">
        <?= $form->field($model, 'fm_upload',[
                    'showLabels'=>false
                ])->widget(FileInput::classname(), [
                'options' => ['accept' => 'image/*'],
                'pluginOptions'=>['allowedFileExtensions'=>['jpg','pdf','png','doc','docx','xls','xlsx']
        ]]) ?>
        </div>
    </div>

    <div class="form-group">
        <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
    </div>

Hope I have provided enough info. Appreciate any help.

EDIT: Here is what the logs looks like, I think its the validation issue but I can't really figure out which one is causing it, the model or the controller.

Check the path is correct and doesn't lack of / for example.

Define your path:

Yii::$app->params['uploadPath'] = Yii::getAlias("@frontend") . '/web/uploads/';

Then, $model->fm_upload doesn't have the value until you save it:

if ($model->load(Yii::$app->request->post())) {
        $file = UploadedFile::getInstance($model, 'fm_upload');

        // store the source file name
        $ext = end((explode(".", $file->name)));

        $new_name = Yii::$app->security->generateRandomString().".{$ext}";

        $path = Yii::$app->params['uploadPath'] . '/' . $new_name;
        $model->fm_upload = $new_name;

        $file->saveAs($path);

        if($model->save()){
            return $this->redirect(['view', 'id'=>$model->_id]);

        } else {
            // error in saving model
        }
    }
