使用以下代码上传多个图片并使用以下代码重命名，压缩，创建缩略图图片一切正常，但上传文件名并不保存到SQL，
有人可以帮助找到代码中的错误吗

答案 0 :(得分：0)
<强> 已更新
PHP GD库提供了几种创建图像对象/资源的功能。这些名称很容易跟随imagecreatefromjpeg()，imagecreatefrompng()等等......但是这些要求您正在为函数提供正确的图像类型，否则它们很可能会失败或出现问题。顺便说一句，没有位图的本机功能。在php.net上，一个人为imaagecreatefrombmp()写了一个非常好的函数。
还有另一个名为imagecreatefromstring()的函数。这是我使用的唯一一个。如果无法从字符串生成对象，此函数也将返回false，因此图像出现问题。
$source = imagecreatefromstring(file_get_contents($file));
if($source){
//Do something with your image. This is where you will do some additional checks for dimensions and for mime-type.
} else{
echo 'There was an error with your image.';
}
至于你所有的错误。它们是不创建有效图像对象/资源的结果。
从错误列表中：
createimagefrompng() - 这是因为图像不是png，或者您没有正确的图像路径。确保检查您正在使用的路径上是否存在该文件。请改用imagecreatefromstring()。imagesx()＆amp; imagesy() - 这些都需要图像资源作为参数。您可以使用imagecreatefromstring()函数获取图像资源。 imagecopyresamped() - 第二个参数需要是资源。再次，使用imagecreatefromstring()生成资源。此外，这很重要。完成后，请确保您正在销毁图像资源。它们会快速消耗大量内存。
imagedestroy($resource)
由于所有错误，您的代码可能甚至无法访问您的查询。
修复所有这些问题然后如果仍然无法解决问题，请使用最新代码发布另一个问题。
