I am looking to auto submit, or possibly prepopulate a form on a second page with information I've collected on a previous page.
That information from the first page is collected from my form, on my domain, and is stored in my database. After the input, I'm redirecting the user to the second page which is a form with the same basic inputs, but is not on my domain name nor do I own.
This second page redirect to the 3rd party form wouldn't even be necessary if the 3rd party form was auto-submitted by curl or some other method.
The problem is that for the second page 3rd party form I have no control over the code. It's not my website, and it's not my form. I don't have any pre-population instructions from the site owner or anything like that.
I'm not sure if submitting a form by Curl or PHP is possible if we don't know anything about the form other than what we can see displayed on the live HTML page.
Also, I need to do this for multiple forms and on multiple websites, but if I can get setup to make this happen and see the code we may be able to replicate it ourselves in the future on other sites.
Summary: I'd like to auto-submit a third party form, with information we collect on our own form...as close to real time as possible and preferably invisible to the user.
If auto-submit is not possible, we are looking for a solution that would allow the prepopulation of the fields at least for the user to click submit.
