将文本区域转换为文件（HTML JQuery AJAX PHP）

Question

I have a question that might have another answer than what I'm thinking of doing.

So, I have a text area that is populated by a DB. I'm allowing the users use it as a notepad and whatnot.

Some of these notes can get pretty big and potentially exceed the URL Character limit. I also have to encode (I'm using encodeURIComponent ) the strings which cuts into the amount of characters too.

I thought the best way would be to convert the text area into a file and then post the file towards my handler php file where it gets uploaded into the db and whatnot. I'm not certain how to do this with JQuery/Javascript or if there was another way to handle this.

Thanks in advance!

    {

        $noteDate = date("M, d Y", strtotime($Notes['updated']));
        $noteTime = date("g:i a", strtotime($Notes['updated']));

• It's probably not a good idea to have file upload where you don't really need. It will be just a security concern
• If you are sending the data through a POST request, the size won't actually be a problem since it's limit is set Server side, on your Apache configs.

To increase the limit POST size limit: Increasing the maximum post size
