guardar方法允许上传一个php文件和图像(jpg和png),在你修改它以便图像自动调整大小,jpg图像的类型效果很好,但是当我尝试上传png文件时它不起作用 . 显示下一个错误:

为什么没有检测到png文件类型,为什么我上传的所有png都检测到它们无效,为什么自动调整jpg的代码也被执行?

我确信这是因为这一行:
if ($_FILES["archivo"]["type"][$key] == "image/jpeg" || $_FILES["archivo"]["type"][$key] == "image/jpg" || !file_exists($target_path))
它评估为true,因为$ target_path上还没有任何文件 . 因此,这些条件总是会评估为真,因为
||
运算符 .建议:
首先检查
!file_exists($target_path))
在外部if然后检查内部if中的图像类型 .就像是:
