我在php中的处理表单如下所示

  $query = "

我的问题是，当我从mysql数据库中插入图像时，它会成功存储。 但是，当我从html表单执行此操作时，它并没有存储图像。它只存储数据文本

我不知道表单中的实际错误是什么。

听起来好像没有错误

您不在数据库中存储实际图像，而只存储它们的名称或对图像的引用

e、 g.product_one.jpg

然后，当您想要显示它时，您可以执行以下操作

<img src=" <?php $echo \images\$users_image_one ?> ">
我想知道对二进制数据使用htmlspecialchars会做什么

$users_image_one = htmlspecialchars($users_image_one);
$users_image_two = htmlspecialchars($users_image_two);
[编辑：]

htmlspecialchars用于保留文本数据的特殊字符。然而，如果你把它用于二进制数据，它会把一切都搞糟

自己解决问题： 你可以先只上传图片来找出问题所在

还可以查看此链接：

这不是文件上载的工作方式。请看，我的建议是将图像上载到特定文件夹中，并将其URL作为varchar存储在数据库中，而不是直接作为blob数据类型。@Kevin添加一些代码并发送回复如何可能TMLSSpecialChars不是转义数据以便将其存储在数据库中的正确方法。还要注意的是，所有mysql_uu函数都已弃用。他还需要做更多的事情。他不是在处理上传的文件all@user2481198对不起，我弄错了。编辑了我的答案。@KevinPaladin$users\u image\u one=htmlspecialchars$users\u image\u one$users\u image\u two=htmlspecialchars$users\u image\u two；如果我用这段代码执行相同的过程，它正在运行。如果我删除此代码，它也会运行。但是图像并不是双向的。@KevinPaladin我认为问题在于我使用的表单action=process.php，但其他一些则表示action=那么我现在起诉的是什么？@user2481198根据Pekka的建议，我建议您先看看这个链接：
