php mysql Multiupload图片文件

Question

我使用表单上传图片。我有2个桌子，一个是product_profile，另一个是product_image。

以我的形式我有2个按钮。一个用于上传product_profile的图片，另一个用于product_image中的图片。

，但是现在我有一个问题，如果else否。它之间是"//检查所有字段都不是空"

当我仅插入product_image文件时" else" if（neget（$ imgfileproduct））"而无需插入profile_image" else" else if（empty（$ imgfile））"，这与消息正确奏效，请选择"请选择图像文件"。<</p>

但是，当我仅插入profile_image时，他会插入数据库中并在不检查product_image是否为空的情况下上传文件，我有关注消息"对不起，只有JPG，JPEG，JPEG，PNG，PNG＆gif＆gif文件2。"而不是"请选择图像文件。"

谢谢您的帮助。

可能是快速修复，

$product_images_count = sizeof($_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(); 
}
