I have two forms: form 1 uses external API, form 2 uses server side PHP. Both forms ask for email. Both work fine but require double entry.

Code form 1:
<form action="http://some.link.com" method="post" target="_blank"><input type="text" name="btr_email" placeholder="Email"><input type="hidden" name="btr_url" value="http://other.link.com"><br>
<input type="hidden" name="schedule_type" value="0"><input type="submit" value="Follow"></form>

Open in new window


Code form 2:
<form class="sml_subscribe" method="post"><input class="sml_hiddenfield" name="sml_subscribe" type="hidden" value="1"><p class="sml_name"><label class="sml_namelabel" for="sml_name">Name:</label><input class="sml_nameinput" placeholder="Name..." name="sml_name" type="text" value=""></p><p class="sml_email"><label class="sml_emaillabel" for="sml_email">Email:</label><input class="sml_emailinput" name="sml_email" placeholder="Email Address..." type="text" value=""></p><p class="sml_submit"><input name="submit" class="btn sml_submitbtn" type="submit" value="Submit"></p></form>

Open in new window


What I need:
1. Remove form 2
2. Add check box in form 1, if checked:
                 
                 -make name input field from form 2 visible
                 -pass email address to form 2
 3. Submit to both forms when "Follow" button is pressed.

Thanks!

The easiest way to do this is to use PHP to parse the initial form submission and then send the form data to the desired targets.

1. I'd rather suggest to hide the form rather then removing it from the HTML structure;
2. add an onchange event to the check object that performs:
-document.getElementById("myField").style.display = "inline";
-document.getElementById("myField2").value=document.getElementById("myEmail1");
3. add an onclick event to the button that performs: document.getElementById("myForm2").submit();
