I'm showing a contact page from another website on my personal website. I want to fill in all of the inputs from a website and submit the contact form. I want to do it manually not with JavaScript. when I sent the form I got an error but when I sent the form via the main website into this domain I can submit the form and I got a successful message. It seems that I don't have access to submit a form into an iframe that is for another domain! can someone help me!
