Php Yii多文件上传

嗨，我在yii做多个文件上传

我有一个设置表使用多个文件上传像这样

myfrom.php

<?php
$form=$this->beginWidget('CActiveForm', array(
    'id'=>'topic-form',
    'enableAjaxValidation'=>false,
    'htmlOptions' => array('enctype' => 'multipart/form-data'), // ADD THIS
));
?>

<div class="row">
<?php
    $this->widget('CMultiFileUpload', array(
        'name' => 'imagepath',
        'model'=> $model,
        'id'=>'imagepath',
        'accept' => 'jpeg|jpg|gif|png', // useful for verifying files
        'duplicate' => 'Duplicate file!', // useful, i think
        'denied' => 'Invalid file type', // useful, i think
    ));
?>
    <div class="row buttons">
        <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
    </div>
</div>

<?php $this->endWidget(); ?>

但只有当我使用多文件上传小部件时，它才会进入if循环。。。（如果（$_POST['Uploadimage']））

单文件上传（如下所示）和上传都可以正常工作，但多文件上传会出现问题

<div class="row">
    <?php echo $form->labelEx($model,'imagepath'); ?>
    <?php echo CHtml::activeFileField($model,'imagepath',array('size'=>60,'maxlength'=>500)); ?>
    <?php echo $form->error($model,'imagepath'); ?>
</div>

我不知道我的代码出了什么问题……我指的是，为了更好地多次上传文件，最好使用这个扩展名。默认的yii多次上传文件也使用jquery插件，但xupload似乎更有效。它对我有效

我也有同样的问题，结果是只有多次上传文件表单上指定的eUpload小部件无法创建$\u POST对象？一旦我添加了第二个输入字段，它就会按预期工作。

我解决了问题，我将示例代码放在下面

查看页面

控制器

$model=new Imgtable;
    // Uncomment the following line if AJAX validation is needed
     $this->performAjaxValidation($model);
    Yii::log("actionCreate actionCreate "  .isset($_POST['Imgtable']));   
    if(isset($_POST['Imgtable']))
    {
        $model->attributes=$_POST['Imgtable'];
        Yii::log("actionCreate actionCreate inside if"  .isset($_POST['Imgtable']));   
        $images = CUploadedFile::getInstancesByName('image');
        Yii::log("actionCreate actionCreate inside if"  .count($images));   
        if(isset($images) && count($images)> 0)
        {
            foreach ($images as $image=>$pic)
            {
                if ($pic->saveAs(Yii::getPathOfAlias('webroot').'/images/'.$pic->name,0777))    
                {   
                     $model=new Imgtable;
                    //$file = CUploadedFile::getInstance($model,'binaryfile');
                    $model->fileName = $pic->name;
                    $model->fileType = $pic->type;
                    $url = Yii::getPathOfAlias('webroot').'/images/';
                    Yii::log("actionCreate actionCreate inside if if"  .$pic->name);
                    $fp = fopen($url.$pic->name, 'r');
                    $content = fread($fp, filesize($url.$pic->name));
                    fclose($fp);
                    $model->binaryfile = $content;
                    $mode = new Productdata; 
                    $last_invoice = Productdata::model()->find(array('order'=>'id DESC'));
                    $last_invoice_number = str_replace("INV:", "", $last_invoice->id);
                    $new_invoice_number = $last_invoice_number;
                    $model->product_id = $new_invoice_number;


                    //$model->setIsNewRecord(true);
                    //$model->id = null;
                   // $model->image = $pic->name;
                    $model->insert();
                }               
            }
                    $this->redirect(array('view','id'=>$model->id));
        }
    }

    $this->render('create',array(
        'model'=>$model,
    ));

我想在你的控制器中，将$更改为

$images = CUploadedFile::getInstancesByName('imagepath');

它将与多重上传一起工作。 请参见我的教程

//100%工作代码
//鉴于
//内部控制器
公共函数actionMultipleupload（）
{
$model=新上传的图像；
如果（isset（$\u POST['Uploadimage']））
{
$model->attributes=$\u POST['Uploadimage']；
$photos=cuploatedfile:：getInstanceByName（'Uploadimage[imagepath]'）；
//如果已设置图像，则继续
如果（设置（$photos）和计数（$photos）>0）{
//浏览每个上传的图片
foreach（$image=>$pic形式的照片）{
if（$pic->saveAs（Yii:：getPathFalias（'webroot'）。/path to image folder/'.$pic->name））{
//现在将其添加到主模型中
$img_add=新上传的图像；
$img\u add->filename=$pic->name；//对于您来说可能是$img\u add->name，filename正是我在模型中选择的名称
$img\u add->topic\u id=$model->id；//这将图片模型链接到主模型（如用户或配置文件模型）
$img_添加->保存（）；//完成
}
否则{
echo“无法上载！”
}
}
}
如果（$model->save（））
$this->redirect（数组（'view'，'id'=>$model->id））；
}
$this->render（'multipleupload'，array（'model'=>$model））；
}

$images = CUploadedFile::getInstancesByName('imagepath');

//100% working code
