JQuery AJAX upload file does not work with files more than 10 MB

Question

I've been stumped with this issue for the past 3 hours. I've looked at countless guides and posts to no avail.

I have a system where users are able to upload files. Once they select a file, I want to upload the file (via PHP file) and show the user the upload progress. I've tried to do this using $.ajax (using FormData) and JQuery Form plugin. They both work with smaller files that are less than 10 MB, but I've found that when I try to upload a file that's more than 10 MB my PHP file receives none of the information ( $_POST or $_FILE ).

How can I fix this issue, or how can I allow users to upload files and show them an accurate upload progress bar?

Thanks in advance.

Answer 1

You should check two vars in your PHP script:

ini_get('post_max_size') , ini_get('upload_max_filesize') and if the user is able to upload multiple files ini_get('max_file_uploads') . If one or all limits are below your expectations you should raise them in your php.ini

Edit: Added upload_max_filesize to the list.

Answer 2

运行ini_get('post_max_size')我发现托管公司将其限制为8MB ，因此我使用php_value post_max_size 128M通过.htaccess将其增加到128MB 。
