php - 上传产品 php 脚本不起作用

Question

我创建了一个 Php 脚本来将产品上传到我的网站，但它不起作用，也没有显示任何错误。我在这个问题上停留了超过 5 天，我仍然发现错误，但我不能请任何人检查我的代码，我需要立即帮助。

您可以检查几项以使其正确。由于这是一个文件资源，因此您还必须在代码之外思考。我知道从过去 5 天开始你已经做了很多研发工作并且可能已经完成了下面提到的所有步骤但是再试一次。我希望它能解决您的问题。

1. 您上传的地方是否有适当的写入权限
2. 在代码之上提供错误报告
3. 在任何使用 move_uploaded_file 的地方创建错误日志
4. 使用断点检查您的代码是否到达代码上传点
5. 如您问题的评论中所述，请检查 move_uploaded_file 函数返回的内容。

6. Check this link also for step by step error check on file upload

   php_value upload_max_filesize = 16G

   php_value post_max_size = 16G

   php_value max_input_time 360​​0

   php_value max_execution_time 360​​0

在您的 .htaccess 中输入此代码，并根据需要更改值。
