Question

您好我正在尝试使用yii上传图片或文件，但它无法正常工作。我没有任何经验，请你帮助我。这是我的代码提前致谢

这是控制器SiteController.php

public function actionCreate()
    {

        $model=new ContactForm;
        if(isset($_POST['save']))
        {

            $model->attributes=$_POST['save'];
            $model->image=CUploadedFile::getInstance($model,'image');
            $path = Yii::app()->basePath . '\uploads';
            //if($model->save())
           // {
                $model->image->saveAs($path);
                // redirect to success page
           // }
        }
        $this->render('index', array('model'=>$model));
    }

这是我的视图文件

<?php
/* @var $this SiteController */

$this->pageTitle=Yii::app()->name;
?>

<h1>Welcome to <i><?php echo CHtml::encode(Yii::app()->name); ?></i></h1><div class="form">
    <?php
    $form = $this->beginWidget('CActiveForm', array(
        'id' => 'document-form',
        'enableAjaxValidation' => false,
        'htmlOptions' => array('enctype' => 'multipart/form-data'),
        'action' => array( 'site/create' )
            ));
    ?>
    <?php
    Yii::app()->clientScript->registerScript('search', "
        $('.search-button').click(function(){
                $('.doc-form').toggle();
                return false;
        });
        $('.doc-form form').submit(function(){
                $.fn.yiiGridView.update('document-grid', {
                        data: $(this).serialize()
                });
                return false;
        });
        ");
    ?>
    <p class="note">Fields with <span class="required">*</span> are required.</p>
        <?php //echo $form->errorSummary($model); ?>
    <div class="row">
        <?php //echo $form->labelEx($model, 'doc_name'); ?>
        <?php //echo $form->textField($model, 'doc_name', array('size' => 50, 'maxlength' => 255)); ?>
        <input type="text" name="doc_name">
        <?php //echo $form->error($model, 'doc_name'); ?>
    </div>
    <div class="row">
        <?php //echo $form->labelEx($model, 'doc_file'); ?>
        <?php //echo $form->fileField($model, 'doc_file', array('size' => 36, 'maxlength' => 255)); ?>
        <input type="file" name="doc_file//">
        <?php //echo $form->error($model, 'doc_file'); ?>
    </div>

    <div class="row">
        <?php //echo $form->labelEx($model, 'summary'); ?>
        <?php //echo $form->textArea($model, 'summary', array('rows' => 6, 'cols' => 50)); ?>
        <input type="text" name="summary">

    <div class="row buttons">

您的index.php视图文件如： -

<?php
$this->pageTitle=Yii::app()->name . ' - Contact Us';
$this->breadcrumbs=array(
    'Contact',
);
?>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'contact-form',
    'enableClientValidation'=>true,
    'clientOptions'=>array(
        'validateOnSubmit'=>true,
    ),
        'htmlOptions' => array('enctype' => 'multipart/form-data'),
)); ?>

    <p class="note">Fields with <span class="required">*</span> are required.</p>
    <?php echo $form->errorSummary($model); ?>
    <div class="row">
        <?php echo $form->labelEx($model,'name'); ?>
        <?php echo $form->textField($model,'name'); ?>
        <?php echo $form->error($model,'name'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'email'); ?>
        <?php echo $form->textField($model,'email'); ?>
        <?php echo $form->error($model,'email'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'subject'); ?>
        <?php echo $form->textField($model,'subject',array('size'=>60,'maxlength'=>128)); ?>
        <?php echo $form->error($model,'subject'); ?>
    </div>
    <div class="row">
        <?php echo $form->labelEx($model,'body'); ?>
        <?php echo $form->textArea($model,'body',array('rows'=>6, 'cols'=>50)); ?>
        <?php echo $form->error($model,'body'); ?>
    </div>
        <div class="row">
            <?php echo $form->fileField($model,'imagePath');?>
        </div>
    <div class="row buttons">
        <?php echo CHtml::submitButton('Submit'); ?>
    </div>
<?php $this->endWidget(); ?>
</div><!-- form -->

您的ContactForm模型必须将CActiveRecord扩展为

<?php

class ContactForm extends CActiveRecord {

    public $imagePath;

    public function tableName() {
        return 'contact_form';
    }

    public function rules() {
        return array(
            array('name, email, subject, body', 'required'),
            array('imagePath', 'file', 'types'=>'jpg, gif, png', 'safe' => false),
            array('id, name, email, subject, body, image, created_on', 'safe', 'on' => 'search'),
        );
    }

    public function relations() {
        return array(
        );
    }

    public function attributeLabels() {
        return array(
            'id' => 'ID',
            'name' => 'Name',
            'email' => 'Email',
            'subject' => 'Subject',
            'body' => 'Body',
            'image' => 'Image',
            'created_on' => 'Created On',
        );
    }

    public static function model($className = __CLASS__) {
        return parent::model($className);
    }

}

您的控制器操作必须

public function actionCreate() {

        $model = new ContactForm;

        if (isset($_POST['ContactForm'])) {

            $model->attributes = $_POST['ContactForm'];
            $model->imagePath = CUploadedFile::getInstance($model,'imagePath');

            $model->image=  Yii::app()->getBaseUrl(true).'/images/logoPhotos/'.$model->imagePath->name;

            if($model->save()){

                $path = Yii::app()->basePath . '/../images/logoPhotos/'.$model->imagePath->name;
                $model->imagePath->saveAs($path);
                $this->redirect($this->createUrl('login'));

            }  

        }

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

您必须使用以下架构

在数据库中创建表

CREATE TABLE CONTACT_FORM ( ID为int(11) NOT NULL AUTO_INCREMENT,名称varchar(255) NOT NULL,电子邮件varchar(255) NOT NULL,受试者varchar(255) NOT NULL,体text NOT NULL,图像varchar(255) NOT NULL, created_on timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, PRIMARY KEY ( ID为) )

上传图片并保存在uploads文件夹中
