Question

嗨我正在yii做多个文件上传...

我有设置表单，可以像这样使用多个文件上传...

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(); ?>

我的控制器方法看起来像......

public function actionMultipleupload()
{
    $model= new Uploadimage();
    if(isset($_POST['Uploadimage']))
    {
        var_dump("inside if");
        //  $images = CUploadedFile::getInstancesByName('images');
    }

    var_dump("out side if");
    $this->render('multipleupload',array('model'=>$model));
}

但只有在我使用多个文件上传小部件时才会进入循环...（if（$ _ POST ['Uploadimage']）

它可以正常运行单个文件上传（如下所示）并上传...但它在多个文件上传中显示问题..

<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this post

Answer 1

我解决了问题，我将示例代码放在下面..

查看页面

<div class="row"> <?php echo $form->labelEx($model,'image'); ?> <?php $this->widget('CMultiFileUpload', array( 'model'=>$model, 'name'=>'image', 'attribute'=>'image', 'accept'=>'jpg|gif|png', 'max'=>4, 'remove'=>'Remove Image ', 'duplicate'=>'Already Selected', )); ?> <?php echo CHtml::submitButton($model->isNewRecord ? 'Upload' : 'Save'); ?>

<强>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,
    ));

我认为在您的控制器中将$ _POST更改为

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

它将适用于multiupload。在这里查看我的教程 http://www.dukaweb.net/2013/12/how-to-do-multiupload-images-in-yii.html

Answer 3

为了更好地多次上传文件，最好使用http://www.yiiframework.com/extension/xupload/这个使用http://blueimp.github.com/jQuery-File-Upload的扩展名。默认的yii多文件上传也使用jquery插件，但xupload似乎更有效。它对我有用

Answer 4

我遇到了同样的问题，事实证明只有在窗体上指定的MultiFileUpload窗口小部件才会创建$ _POST对象？一旦我添加了第二个输入字段，它就会按预期工作。
