How many max characters to send via POST Method?

I just make some web using this free hosting, and when i sending a text with type data longtext in sql, but whene i send text with more than 10000 character with method post that is not save in sql?

Hmm, I’m not sure exactly what the problem is you’re talking about. Is the submitted data truncated when submitting the post request or when saving it to the database? If you could set up a test file and just echo out the submitted POST data, you should be able to see whether it gets truncated.

That said, the total limit for POST data is 10 MB and the limit of a LONGTEXT field in MySQL is 4 GB, so unless you have some extremely complex encoding for those 10,000 characters, I’m not sure why the data would be truncated.
