向清单文件添加文件字段

Question

我的插件需要用户上传文件。

清单字段未设置 enctype="multipart/form-data" 形式，因此当文件上传时它会丢失。

有办法改变吗？

Answer 1

    for xml :
            Joomla File form field type in xml:
            https://docs.joomla.org/File_form_field_type
            <field name="myfilevalue" type="file" label="Enter some text" description="Choose an image from your computer with maximum 100KB" size="10" accept="image/*" />


            OR 
            if your file field in html form then used :
            <input type="file" name="jform[myfilevalue]" >

希望对你有所帮助，否则请提供更多描述

                            <field name="con_image" type="file" label="" description="" hint="Image"/>
