我是 PHP的新手,我需要一些上传图片的帮助.我需要允许用户上传图像,我希望将该图像保存在目录(www / CakePHP / app / webroot / img /)中,并且还希望数据库存储图像的文件路径.这是我到目前为止所得到的,

ProductsADD.ctp：

<div class="products form">
<?php echo $this->Form->create('Product'); ?>


    <fieldset>
        <legend><?php echo __('Add Product Details'); ?></legend>
    <?php
        echo $this->Form->input('product_name',array('required'=>false));
        echo $this->Form->input('product_model_number',array('required'=>false));
        echo $this->Form->input('product_brand',array('required'=>false));
        echo $this->Form->input('product_description',array('required'=>false));
        echo $this->Form->input('price_bronze',array('required'=>false));
        echo $this->Form->input('price_silver',array('required'=>false));
        echo $this->Form->input('price_gold',array('required'=>false));
        echo $this->Form->input('upload',array('type'=>'file'));


    ?>
    </fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>

ProductsController的：

public function add() {
            if ($this->request->is('post')) {
                $this->Product->create();
                if ($this->Product->save($this->request->data)) {
                    $this->Session->setFlash(__('The product has been saved.'));
                    return $this->redirect(array('action' => 'index'));
                } else {
                    $this->Session->setFlash(__('The product could not be saved. Please,try again.'));
                }
                if(!empty($this->data))
                {
                    //Check if image has been uploaded
                    if(!empty($this->data['products']['upload']['name']))
                    {
                        $file = $this->data['products']['upload']; //put the data into a var for easy use

                        $ext = substr(strtolower(strrchr($file['name'],'.')),1); //get the extension
                        $arr_ext = array('jpg','jpeg','gif'); //set allowed extensions

                        //only process if the extension is valid
                        if(in_array($ext,$arr_ext))
                        {
                            //do the actual uploading of the file. First arg is the tmp name,second arg is
                            //where we are putting it
                            move_uploaded_file($file['tmp_name'],WWW_ROOT . 'CakePHP/app/webroot/img/' . $file['name']);

                            //prepare the filename for database entry
                            $this->data['products']['product_image'] = $file['name'];
                        }
                    }

                    //now do the save
                    $this->products->save($this->data) ;
                }
            }

        }

我似乎无法弄清楚为什么上传的图像不会保存到目录中.有人可以请帮助.

解决方法

在使用文件输入在cakephp中创建新表单时,您必须设置’enctype’=>’multipart / form-data’

代码应该是这样的：

<?php echo $this->Form->create('Product',array('enctype'=>'multipart/form-data')); ?>

我希望这会奏效
