Submit Button Needs To Be Clicked Twice To Get My Results From Radio Buttons In A Php Script

The problem with this code is that I can't read the results in $survey_Answers1 except after clicking on the submit button twice. file:survey.php

Solution 1:

Try to insert after for-loop

for ($i = 1; $i <= 2; $i++)
{
   // your code here
}
if (empty($_POST['h2'])) $_POST['h2'] = $survey_Answers1; // insert this line

Or use JavaScript, insert to the end of file:

<scriptsrc="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script><script>
    $(function(){
        if ($('form').length > 0) {
            $('form').submit(function(e){
                var answers = '';
                $('input[type=Radio]:checked').each(function() {
                    if (answers !== '') {
                        answers += ',';
                    }
                    answers += $(this).val();
                })
                $('input[name=h2]').val(answers);

            });
        }
    })
</script>

Solution 2:

From what I see your problem is with your for loop try to see whats returning survey_Answers1 in each loop. you can try this to see whats returning each time it loops and part from there

if (isset($_POST[$qNum])){
   $survey_Answers1 = $survey_Answers1.', '.$_POST["$qNum"];
?>
   <script type="text/javascript"><?phpecho$survey_Answers1; ?></script>
<?php
        }
