Php + Mysql + 多上传图片文件

Question

我使用表单上传图片。 我有两张表，一张是product_profile，另一张是product_image。

在我的表单中，我有 2 个按钮。一个上传product_profile的图片，另一个上传product_image中的图片。

但现在我遇到了 if、else if 和 else 的问题。在“//检查所有字段不为空”之间

当我只为 product_image "else if(empty($imgFileProduct))" 插入文件而不为 profile_image "else if(empty($imgFile))" 插入文件时，这与消息“请选择图像文件”正常工作。

但是当我只插入 profile_image 时，他插入数据库并上传文件而不检查 product_image 是否为空，并且我有以下消息“对不起，只允许 JPG、JPEG、PNG 和 GIF 文件2。”而不是“请选择图像文件”。

感谢您的帮助，一整天都在这。

一个快速的解决方法可能是，

$product_images_count = sizeof($_FILES['product_image']);

for($i=0; $i<$product_images_count; $i++) {
    $ProductimgFile = $_FILES['product_image'][$i]['name'];
    $Producttmp_dir = $_FILES['product_image'][$i]['tmp_name'];
    $ProductimgSize = $_FILES['product_image'][$i]['size'];
    do_something_with_those_variables(); 
}
