Phalcon hasFiles() 总是 return true

Question

当检查 if 条件为 if ($this->request->hasFiles() == true) 时，文件上传功能总是返回 true；即使没有上传任何文件。

当表单为空时收到消息为：

File format not supported

注意： 但是上传图片时工作正常。

HTML 表单是使用 Phalcon tag 创建的。下面是来自 controller 的函数并使用 volt 显示 form.

控制器：

function imageupload()
{
    if ($this->request->hasFiles() == true)
    {
        $upload_dir = BASE_PATH . '/files/';
        foreach ($this->request->getUploadedFiles() as $file) {
            if($file->getSize()>1000000)
            {
                $this->flash->error("File too big");
                return  false;
            }
            if(!in_array($file->getRealType(),array('image/jpg','image/jpeg','image/png','image/gif')))
            {
                $this->flash->error("File format not supported");
                return  false;
            }
            if($file->isUploadedFile())
            {
                $filename=rand().'_'.date('Ymdhis').'.'.$file->getExtension();
                $file->moveTo($upload_dir . $filename);
                return $filename;
            }
            else
            {
                $this->flash->error($file->getError());
                return  false;
            }
        }
    }
    return true;
}

查看：

        <?php
    echo $this->tag->form(['company/create','enctype'=>'multipart/form-data']);
    ?>
    <p>
        <label for="name">Name</label>
        <?php echo $this->tag->textField("name"); ?>
    </p>
    <p>
        <label for="logo">Logo</label>
        <?php echo $this->tag->fileField("logo"); ?>
    </p>
    <p>
    <p>
        <?php echo $this->tag->submitButton("Create"); ?>
    </p>
    <?php $this->tag->endForm(); ?>

调用上传函数：

<?php
    $logoname=$this->imageupload();
    if($logoname==false)
    {
        $this->dispatcher->forward(['action' => 'new']);
    }
    else
    {   
        ......
        ....
        $success = $form->save();
        if($success)
        {
            $this->flash->success("Company successfully saved!");
            $this->dispatcher->forward(['action' => 'index']);
        }
        else
        {
            $this->flash->error("Following Errors occured:");
            foreach($company->getMessages() as $message)
            {
                $this->flash->error($message);
            }
            $this->dispatcher->forward(['action' => 'new']);
        }
    }
    ?>

Answer 1

通过修改 if 条件，如下所示：

if ($this->request->hasFiles(true) == true)

Phalcon hasFiles() 总是 return true

Phalcon hasFiles() always return true

php

file-upload
