Are you struggling to solve issue while submitting your form in php? and getting an unexpected error 403 Error? Have you checked your code twice thrice or more 🙂 Well, actually this is not error in your code.
Reasons of 403 Error
On online servers there is security in Apache servers like firewalls they stop injections to servers from forms, Actually if your form is not submitted many times still this problem can arise if you are submitting 2 or more files together in single form this is the common reason when you send your form via http:// protocol mod security module in Apache server stop the form to submit data in it maybe this will run few lines but not complete code and will return this Error.
The reason is your server’s security mode security module so if you are using shared hosing and don’t have permission to edit mode security Apache module then you can do nothing. Also the reason why mode security module thinks multiple files submission as attack or spam and return 403 error because of multiple files in 1 HTTP request, you may not get this error in https:// protocol.
The most main and common reason for this is sending HTML code in your forms to HTTP , So if you are sending HTML code in your forms in multiple fields then 403 error can come up.
Solutions for 403 Error
If your problem is cause of multiple files uploading returning this error, I suggest you divide your single form into multiple forms, and then submit you will not get this problem, try to send 1 file in 1 form only, This can be solution of 403 error.
If you cannot divide your form into multiple forms then you still no need to worry cause you have help available you can send your data to server via Jquery.
See if you are submitting multiple fields with html submission you have to divide them into multiple forms as well cause HTML submission is big reason of 403 error. I will keep writing about this error.
