我正在尝试创建我的第一个准备好的声明。有了这个，我也试图将我的第一个图像文件发送到我的数据库。我一直在研究这个问题已经有一个月左右的时间了。我最初尝试用一个带有php的简单插入命令来执行此操作，除了img文件的名称外，所有内容都插入到我的数据库中。我被告知多次使用准备好的声明来创建它，所以我这样做，但没有任何东西发送到我的数据库，我无法找出原因。
我通过验证某些数据字段来启动代码。我还没有验证img文件，但稍后会。验证不是问题，因为我把它打破了一点，它正在通过它。
我没有发生任何错误。我甚至在执行语句时会添加会产生任何语法错误的内容，但这不会产生任何错误。
有没有人看到我在这里做错了会导致这种情况无法发送？是否与我的img文件有关，或者我是否正确地编写了预处理语句？
