在我的项目中，我使用多个选项上传图像，但文件名显示为空白。这是我的代码。

但是当我提交表单时，它会替换＆＃34; ALBUM IMAGE是必需的＆＃34; ，当我显示$_FILES['product']['name']时，它显示空白或null但是它是如何＆ ＃39; s发生了???请帮助我。
答案 0 :(得分：2)
要上传文件，我们在表单标记
中使用enctype="multipart/form-data">
所以而不是
<form action="../../controllers/tileesDesign/add.php" method="post" class="form-horizontal addSizeForm" id="addSize">
使用
<form action="../../controllers/tileesDesign/add.php" method="post" class="form-horizontal addSizeForm" id="addSize" enctype="multipart/form-data">
