you can find a similar question here PHP Post Request inside a POST Request but this is not working in my context.
I have a form (reservation form for a tour website) and when the form is submitted, the values are processed in a script like validation and calculation of values and sending email.
after processing the variables, i want to send it to a page for payment and this page will post payment details to paypal.
My question is after the reservation form is submitted, after processing values retrieved from reservation from, how can i redirect the page in such a way that the variables will be passed as post variables. (I am not looking from response from the other form, i want to redirect to the other form).
