答案 0 :(得分：1)
检查表单输入的名称：
<input type="file" name="product_image">
此错误输入名称“ product_image”不存在。
和表单的 enctype ：
<form action="" method="post" enctype="multipart/form-data">
答案 1 :(得分：0)
它现在可以正常工作
<form method="post" enctype="multipart/form-data" id="product_form">
这是答案感谢您解决我的问题我的查询很好，所以这是我的真正问题哈哈抱歉，我是初学者
