我在使用基本表单在数据库中插入图像时遇到问题。有两种形式，一种是插入类别（图像和名称），另一种是插入位置（名称，地址，图像等）。 add_category函数工作正常，它是add_location，没有并且专门插入图像。而且我相信它会插入有问题的图像。
问题是插入图像中的if语句永远不会被执行，我不知道为什么。它位于检查图像if语句下的函数add_location(..)中。
if ($result = $this->mysqli->query($query)) {
$error['result'] = $this->succAddLoc;
}
我删除了文件中不必要的函数：

答案 0 :(得分：1)
替换：
$ image = $ _FILES [＆＃39; image＆＃39;];
带
$ image = $ _FILES [＆＃39; image＆＃39;] [＆＃39; name＆＃39;];
如果您想要图像名称
或：
使用：
$ image = $ _FILES [＆＃39; image＆＃39;] [＆＃39; tmp_name＆＃39;];
如果你的意思是文件
答案 1 :(得分：0)
试试这个$image = $_FILES['image']['name'];而不是$image = $_FILES['image'];
答案 2 :(得分：0)
$ _ FILES [＆＃39; image＆＃39;]包含上传文件的所有相关信息的数组，如名称，类型，大小，错误，tmp_name，因此您需要调用的数据如下：
$ _ FILES [＆＃39;图像＆＃39;] [＆＃39;名称＆＃39;] $ _FILES [＆＃39; image＆＃39;] [＆＃39; type＆＃39;]等。
希望这有助于你...... :)
答案 3 :(得分：0)
将图像插入数据库并不是一个好主意。建议您将上传的图像移动到给定目录中，并将图像的路径保存到数据库中。
答案 4 :(得分：0)
只需执行以下操作..
$image=$_FILES['image']['name'];
以上述方式获取 $ image 变量中的值，确定您的问题将得到解决。
