upload joomla file mysql php

<field
    type="file"
    name="category_image"
    accept="image/*"
    label="COM_SKYCATALOG_ITEM_CATEGORY_IMAGE_LABEL"
    directory=""
    preview="false"
/>

然后更新 save()

$jinput = JFactory::getApplication()->input;
$files = $jinput->files->get('jform');      

$fileinfo =pathinfo($files['category_image']['name']);

$ext = $fileinfo['extension'];
$filename = time().".$ext";     

$tmp_file = $files['category_image']['tmp_name'];

$dest = "../media/com_xxxxx/upload/".$filename;

if (JFile::upload($tmp_file, $dest)) {
      // successed :)
} else {              
     // failed :(
echo "FAAAIL!!!";
die();
}

这里可能有什么问题?

我设法解决了这个问题。无法设置的值 input 标记为 file 类型,因为安全原因。我的意思是你可以设置 value

我只是创建了一个自定义字段,如下所示:

class JFormFieldSkyupload extends JFormField
{
    /**
     * The field type.
     *
     * @var         string
     */
    protected $type = 'Skyupload';

    /**
     * Method to get a list of options for a list input.
     *
     * @return  array  An array of JHtml options.
     */
    public function getInput() {
        return '<div class="filename_labe">'.$this->value.'</div><input name="'.$this->name.'" id="'.$this->id.'" accept="image/*" aria-invalid="false" type="file" value="'.$this->value.'">';
        // code that returns HTML that will be shown as the form field
    }

}

此外,我还对上传代码进行了一些更改,因此即使没有选择新文件,我也能够毫无错误地保存表单:

if ($files['category_image']['name']!="")
{
    $fileinfo =pathinfo($files['category_image']['name']);

    $ext = JFile::getExt($files['category_image']['name']);
    $filename = time().".$ext";

    $tmp_file = $files['category_image']['tmp_name'];

    $dest = "../media/com_skycatalog/upload/".$filename;

    if (JFile::upload($tmp_file, $dest)) {
    // successed :)
    } else {                  
    // failed :(
    echo "FAAAIL!!!";
    die();      
    }        

$data = JRequest::getVar( 'jform', null, 'post', 'array' );
$data['category_image'] = strtolower( $filename );
JRequest::setVar('jform', $data );

}

现在,只有我上传新文件时,它才会更新数据库中的文件名。
