Foreach only prints one value from array when using Ajax and onsubmitForm

Foreach only prints one value from array when using Ajax and onsubmitForm

I'm using Ajax to POST a value to another page without refreshing the
current page, but when I add the form HTML to the Foreach argument, it
will only print out one of the first of the 50 array values.
If I don't include onsubmit='return SubmitFor();' the Ajax script won't
run on click, but the Foreach will print all of the array values.
Here is my Foreach:
foreach ($Results as $arrResult) {
$IDstring = $arrResult['id_str'] ;
print("<form id='RT' onsubmit='return submitForm();'><input
type='hidden' name='id' value=$IDstring><input type='submit'
value='RT'></form></div>");
}
So I'm assuming that this onsubmit='return SubmitFor();' is the issue? Is
it not possible to include that with a PHP foreach? How can I get print to
print all the array values instead of the first result only?
