I have combined PHP validation and PHPmailer, the code is working perfectly. The only problem I am facing now is whenever I click submit, the message "textarea" is getting empty, therefore I have to retype the whole message again. Example: if the name is wrongly entered and all other fields are OK, when you click submit it will show the warning message under the name field but the message will be coming empty, I hope I have delivered my message in a proper way. *I am using PHPmailer without composer.
