我有一个问题插入图像在我的数据库中的基本形式。有两种形式，一种插入类别（图像和名称），另一种插入位置（名称，地址，图像等）。 add_category函数工作正常，它不是add_location，并且特别插入图像。我相信它会插入有问题的图像。无法将图像插入数据库
问题是，如果插入图像中的if语句永远不会执行，我不知道为什么。它在检查图像if语句下的功能add_location(..)中。
if ($result = $this->mysqli->query($query)) {
$error['result'] = $this->succAddLoc;
}
我删除了文件中不必要的功能：

如果if（）永远不会被执行，然后查看它之前的代码并找出原因。你也不会说如果不工作 - 你在这段代码中有很多......我们不打算通读一段代码来尝试和猜测你正在谈论哪个部分。 –
@MarcB感谢您的评论。它在//检查图像文件下的函数add_location中。我编辑了我的问题。我查看了if语句之前的内容，并没有发现任何错误，这与我用于add_category的代码相同，可以正常工作。 –
一个很好的做法是放弃W3fools上传处理代码....来自该网站的PHP代码应该被视为核废料。 –
