apache - PHP upload greater than 64MB has no POST variables

Hey everyone,

I'm facing an issue with my Apache server and PHP configuration, specifically related to uploading files larger than 64MB. When I try to upload a file of that size or larger, I noticed that the POST variables are not being passed to my PHP script. However, smaller file uploads work perfectly fine.

I have already made changes to the following PHP configuration settings:

1. `upload_max_filesize`: I set this to a value greater than 64MB, like `128M`.
2. `post_max_size`: I ensured that this value is set higher than `upload_max_filesize`, like `256M`.

I have also restarted my Apache server after making these changes. Despite that, I am still encountering this issue with larger file uploads.

I'm not sure if there are any other Apache or PHP configurations that I need to tweak to make this work. Can anyone guide me on what could be causing this problem and how I can allow for larger file uploads while still retaining the POST variables in my PHP scripts?

Any help would be greatly appreciated! Thanks in advance.

Hey folks,

I faced a similar issue with lost POST variables during larger file uploads, and I wanted to share my experience in resolving it. In my case, the problem turned out to be related to the `max_execution_time` setting in PHP.

When uploading larger files, the processing time can sometimes exceed the default `max_execution_time` value, causing the script to terminate before completing the POST variable handling. To address this, increasing the `max_execution_time` value might do the trick.

To make the necessary adjustment, locate your `php.ini` file and search for the `max_execution_time` directive. By default, it's usually set to 30 seconds. Try increasing it to a higher value, like 60 seconds or more, to accommodate the longer processing time required for larger uploads. Don't forget to save the changes and restart Apache for them to take effect.

By extending the `max_execution_time`, PHP will allow sufficient time for the upload and post-processing tasks, ensuring that the POST variables are handled properly for larger file uploads.

Give this solution a shot, and I hope it resolves the issue for you too! If you have any further questions or need additional assistance, feel free to ask.


Hi everyone,

I encountered a similar issue with larger file uploads and the missing POST variables. After some troubleshooting, I discovered that the issue was related to the `memory_limit` configuration in PHP. Therefore, if you're facing the same problem, this might be worth checking.

By default, the `memory_limit` is set to a relatively low value, such as 128MB. When uploading larger files, PHP needs more memory to process the request and handle the POST variables. Hence, increasing the `memory_limit` might resolve the issue.

To do this, locate your `php.ini` file and search for the `memory_limit` directive. Change the value to a higher limit, such as 256MB or even 512MB if your server resources allow. Don't forget to save the changes and restart Apache for the modifications to take effect.

Once I made this adjustment, my PHP scripts successfully received the POST variables even for larger file uploads.

Feel free to give this a try and let me know if it works for you! If you have any further queries or need assistance, don't hesitate to ask.


Hey there,

I faced a similar issue in the past, and after some troubleshooting, I found a solution that worked for me. The problem might be related to the `max_input_vars` configuration in PHP.

To verify if this is the case, open your `php.ini` file and search for `max_input_vars`. By default, this value is set to 1000, which means that PHP will only process the first 1000 form fields. If your larger file upload contains more than 1000 form fields, the additional fields might not be received by your PHP script.

Try increasing the value of `max_input_vars` to a higher number, such as 5000 or 10000, and then restart your Apache server. This should allow PHP to process more form fields, ensuring that your POST variables are received even for larger file uploads.

Remember to save your changes in the `php.ini` file and restart Apache to apply the updated configuration.

I hope this helps! Let me know if you have any further questions.
