I was doing a project and it required that I sent the same information to 2 different sites using 2 different forms. It wasn’t easy to edit the back end code so I couldn’t used the API. After researching I came up with this solution.
- Hide the second form with CSS
<form style="display:none;"....
- When the first form is submitted do 3 things.
- Populate the second form using the values from the first. I used jQuery .val
var name = $("#name").val(); $("#name2").val(name); - Send the first form through an IFrame.
<form target="iFrameID"....
- Set the thank you page for the form to come back to an html file with basic HTLM code and a script like this to trigger a function to send the second form. This page has to be on the original domain so it doesn’t violate the cross domain rules.
<script> parent.sendForm2(); </script>
- Populate the second form using the values from the first. I used jQuery .val
Example of code for the main page….
<iframe id="iFrame1" name="iFrame1"></iframe>
<form id="form1" target=”iFrame1″>
Name: <input type=”text” id=”name” name=”name”/>
</form>
<form id=”form2″ style=”display:none;”>
Name: <input type=”text” id=”name2″ name=”name”/>
</form>
<script>
function sendForm1(){
$(“#form1”).submit();
}
function sendForm2(){
$(“#form2”).submit();
}
function populateForm2(){
var name = $(“#name”).val();
$(“#name2”).val(name);
sendForm1();
}
$("#form1").submit(function() {
populateForm2();
return false;
});
</script>
Example of code for the thank you page (for the first form) HTML file ….
<!DOCTYPE html> <html lang="en-US"> <head> <meta charset="UTF-8"> <script> parent.sendForm2(); </script> </head> <body> <p>Sending...</p> </body> </html>
Note: This page has to be on the original domain so it doesn’t violate the cross domain rules. If you need to do it with a subdomain you could add document.domain = “subdomain.mydomain.com”; to the main page and the thank you page.
