I managed to try one out but it's not working in my end: http://www.yiiframework.com/doc-2.0/guide-input-file-upload.html
There's no error message and the data are not saved in the database (MongoDB). Here are my code snippets:
Contact.php Model
class Contact extends ActiveRecord
{
public $file;
public $attachment;
/**
* @inheritdoc
*/
public static function collectionName()
{
return ['iaoy', 'contact'];
}
/**
* @inheritdoc
*/
public function attributes()
{
return [
'_id', 'fname','lname','email','phone','address','contact_type','business_name','notes','company_id','date_added','attachment','sort', 'urls'
];
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['_id', 'fname','lname','email','phone','address','contact_type','business_name','notes','company_id','date_added','attachment','sort', 'urls'], 'safe'],
[['fname','lname','contact_type','business_name'], 'required'],
[['attachment'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg', 'maxFiles' => 10, 'maxSize'=>20*1024*1024,],
//[['urls'],'string'],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
//'contact_id' => 'Contact ID',
'_id' => 'Contact ID',
'contact_type' => 'Contact Type',
'business_name' => 'Business Name',
'fname' => 'First Name',
'lname' => 'Last Name',
'email' => 'Email',
'phone' => 'Phone',
'address' => 'Address',
'notes' => 'Notes',
'attachment' => 'Attachment',
'company_id' => 'Company ID',
];
}
public function upload()
{
if ($this->validate()) {
foreach ($this->attachment as $file) {
$file->saveAs('archive/contact/' . $file->baseName . '.' . $file->extension);
}
return true;
} else {
return false;
}
}
}
ContactController.php Controller
public function actionCreate()
{
$session = Yii::$app->session;
$model = new Contact();
if($model->load(Yii::$app->request->post())) {
//if (Yii::$app->request->isPost) {
$model->company_id = new \MongoId($session['company_id']);
date_default_timezone_set('Asia/Manila');
$model->date_added = date('d-m-Y', time());
$model->attachment = UploadedFile::getInstance($model, 'attachment');
/*if($model->attachment) {
foreach ($model->attachment as $key => $file) {
$file->saveAs('archive/contact/'. $file->baseName . '.' . $file->extension); //Upload files to server
$model->urls .= 'archive/contact/' . $file->baseName . '.' . $file->extension.'**'; //Save file names in database- '**' is for separating images
}
$path = 'archive/contact/' . $model->attachment->baseName . '.' . $model->attachment->extension;
$count = 0;
{
while(file_exists($path)) {
$path = 'archive/contact/' . $model->attachment->baseName . '_'.$count.'.' . $model->attachment->extension;
$count++;
}
}
$model->attachment->saveAs($path);
$model->attachment = $path;
}*/
$model->save();
if($model->save()) {
Yii::$app->session->setFlash('success', "Successfully created contact!");
} else {
$model->save();
if($model->save()) {
Yii::$app->session->setFlash('success', "Successfully created contact!");
} else {
Yii::$app->session->setFlash('error', "Contact creation failed!");
}
}
$model->refresh();
return $this->redirect(['index', 'id' => $session['user_id']]);
} else {
return $this->renderAjax('create', [
'model' => $model,
]);
}
}
_form.php View
echo FileInput::widget([
'model' => $model,
'attribute' => 'attachment[]',
'name' => 'attachment[]',
'options' => [
'multiple' => true,
'accept' => 'image/*'
],
'pluginOptions' => [
'showCaption' => false,
'showRemove' => false,
'showUpload' => false,
'browseClass' => 'btn btn-primary btn-block',
'browseIcon' => '<i class="glyphicon glyphicon-camera"></i> ',
'browseLabel' => 'Attach Business Card',
'allowedFileExtensions' => ['jpg','gif','png'],
'overwriteInitial' => false
],
]);
I'm not sure what seems to be lacking or wrong. Is it because I am using MongoDB or Kartik's widget? Please let me know your thoughts below.
I finally got it. Here's what I did:
$model->attachment = UploadedFile::getInstances($model, 'attachment');
if ($model->attachment) {
foreach ($model->attachment as $attachment) {
$path = 'archive/contact/' . $attachment->baseName . '.' . $attachment->extension;
$count = 0;
{
while(file_exists($path)) {
$path = 'archive/contact/' . $attachment->baseName . '_'.$count.'.' . $attachment->extension;
$count++;
}
}
$attachment->saveAs($path);
$files[] = $path;
}
$model->attachment = implode(',', $files);
}
$model->save();
First off, I forgot that it should be getInstances()
with an 's' since it's a multiple file upload. Then I put the code in a foreach
loop then used implode
to save the urls/paths as strings separated by a comma.
From the article you posted:
if (Yii::$app->request->isPost) {
$model->imageFile = UploadedFile::getInstance($model, 'imageFile');
if ($model->upload()) {
// file is uploaded successfully
return;
}
}
The upload method is in the first code block and saves the file on the filesystem
public function upload()
{
if ($this->validate()) {
$this->imageFile->saveAs('uploads/' . $this->imageFile->baseName . '.' . $this->imageFile->extension);
return true;
} else {
return false;
}
}
If you want to save it as binary to your Database, you'd need to read the contents of the file (eg file_get_contents ) and assign it to the model attribute.
Note that, if you're using a standard ActiveForm, you need to tell it that it's expecting multiple files, eg:
echo $form->field($modelImage, 'imageFiles[]')->fileInput(['multiple' => true]);
rather than:
echo $form->field($modelImage, 'imageFiles')->fileInput(['multiple' => true]);
