我在使用Yii2在postgresql中上传多个文件名时遇到问题，我有一个名为“i006t_factura”的表，其中有一个iD，一个名为“id_obra”的外键和一个“ruta”，这是我要保存的地方图像文件，但如果我有多个文件，那么我必须为“id_obra”保存多个名称，所以这是我的模型的代码：
<?php
namespace app\models;
use Yii;
/**
* This is the model class for table "i006t_factura".
*
* @property integer $id
* @property integer $id_obra
* @property string $ruta
*
* @property C004tObraSocial $idObra
*/
class Factura extends \yii\db\ActiveRecord
{
public $ruta;
/**
* @inheritdoc
*/
public static function tableName()
{
return 'i006t_factura';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['id'], 'required'],
[['id_obra'], 'required'],
[['id_obra'], 'integer'],
[['ruta'], 'safe'],
[['ruta'], 'file', 'extensions'=>'jpg, gif, png',
'maxFiles' => 8,],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'id_obra' => 'Id Obra',
'ruta' => 'Ruta',
];
}
/**
* @return \yii\db\ActiveQuery
*/
public function getIdObra()
{
return $this->hasOne(C004tObraSocial::className(), ['id' => 'id_obra']);
}
public function afterSave($insert, $changedAttributes)
{
if(isset($this->ruta)){
$this->ruta=UploadedFiles::getInstance($this,'ruta');
if(is_object($this->ruta)){
$path=Yii::$app->basePath . '/archivos/'; //set directory path to save image
$this->ruta->saveAs($path.$this->id_obra."_".$this->ruta); //saving img in folder
$this->ruta = $this->id_obra."_".$this->ruta; //appending id to image name
\Yii::$app->db->createCommand()
->update('organization', ['ruta' => $this->ruta], 'id = "'.$this->id_obra.'"')
->execute(); //manually update image name to db
}
}
}
}

错误是当它想要上传图像时，“ruta”为空，因为它没有检测到URL，我不知道我的代码的某些部分是否需要迭代循环！
感谢您的回答！
答案 0 :(得分：0)
好吧，我解决了部分问题，即保存图片网址，但是对于一张图片！当我尝试将getInstances用于多个图像时，仍然有错误！
这是来自我的控制器的actionCreate（）：
public function actionCreate()
{
$model = new Factura();
if ($model->load(Yii::$app->request->post())) {
// Here is where I obtain the image
$model->file = UploadedFile::getInstance($model, 'file');
if($model->file){
$imagepath = 'archivos/';
$model->ruta = $imagepath .rand(10,100).'-'.$model->file->name;
}
if($model->save()){
if($model->file){
$model->file->saveAs($model->ruta);
}
return $this->redirect(['view', 'id' => $model->id, 'id_obra' => $model->id_obra]);
}
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
这是我更新的_form.php：
<div class="factura-form">
<?php $form = ActiveForm::begin(['options'=>['enctype'=>'multipart/form-data']]); ?>
<?= $form->field($model, 'id')->textInput() ?>
<?= $form->field($model, 'id_obra')->textInput() ?>
//Where I submit my image
<?= $form->field($model, 'file')->fileInput() ?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
所以，仍有多个图像问题...不知道它与db表有关...
