php - Form loading external script after submiting

187

I have a form like this:

<!DOCTYPE html>
<html>

  <head>
    <meta charset="utf-8">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
    <link href="https://fonts.googleapis.com/css?family=Raleway:200" rel="stylesheet">
    <link rel="stylesheet" type="text/css" href="resources/style.css">
    <link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css" rel="stylesheet" integrity="sha384-T8Gy5hrqNKT+hzMclPo118YTQO6cYprQmhrYwIiQ/3axmI1hQomh7Ud2hPOy8SP1" crossorigin="anonymous">
  </head>

  <body>

    <nav >
      <div >
        <div >
          <a href="#">Footer Generator</a>
        </div>

        <ul >
          <li ><a href="#">Home</a></li>
        </ul>
      </div>
    </nav>

    <!-- Customize your footer and submit -->
    <div id="container">



    <form class ="formFooter" method="post" action= "script.php">

      <h3>Select your trademark</h3>

        <select name="trademark">

          <option></option>
          <option>©</option>
          <option>™</option>
          <option>®</option>

        </select>

      <h3>Your company name</h3>

        <input type="text" name="companyName" placeholder="Your company name" />

        <h3>Background Color</h3>


        <input placeholder="(e.g. 00ff00)" type="text" name="backgroundColor">

        <h3>Font Color</h3>


        <input placeholder="(e.g. 00ff00)" type="text" name="fontColor">


        <h3>Opacity</h3>


        <input placeholder="(Pick a value between 0 and 1 e.g. 0.3)" type="text" name="opacity">


        <br/>
        <br/>

        <button type= "submit" name= "submit">Generate footer</button>
    </form>


    </div>
    <div id="footer_date"> © 2016 Footer Generator </div> 
  </body>
</html>

The form has an action which leads to "script.php", here is the script:

<?php
function footerPreview ()
{
echo "<h3>Preview:</h3>";
date_default_timezone_set('UTC');
$trademark = $_POST["trademark"];
$company = $_POST["companyName"];       
$date = date("Y");
//style
$backgroundColor = $_POST['backgroundColor']; 
$fontColor = $_POST['fontColor']; 
$opacity =  $_POST['opacity']; 

echo "<div id='generated_footer_date' style='background-color:$backgroundColor; color:$fontColor; opacity: $opacity; ' >$trademark $date $company </div>";          

}


// generate result for the head
function rawHead()
{
$head = htmlspecialchars('<head>
<meta charset="utf-8">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://fonts.googleapis.com/css?family=Raleway:200" rel="stylesheet">
</head>',ENT_QUOTES);
echo "<pre><h4>Put this code inside your head tags</h4>$head</pre>";
}



// generate result for the body
function rawBody ()
{
$body1of5 = htmlspecialchars('<div id="footer_date">',ENT_QUOTES);
$body2of5 = $_POST["trademark"];
$body3of5 = date("Y");          
$body4of5 = $_POST["companyName"];
$body5of5 = htmlspecialchars('</div>',ENT_QUOTES);
echo "<pre><h4>Put this code inside your body tags</h4>$body1of5 $body2of5 $body3of5 $body4of5 $body5of5 </pre>";
}

// generate result for the CSS
function rawCSS () 
{
$opacity =  $_POST['opacity']; 
$backgroundColor = $_POST['backgroundColor'];
$fontColor = $_POST['fontColor'];
echo 
"<pre>
<h4>Put this code in your websites stylesheet</h4>
color:$fontColor;
background-color:$backgroundColor;
opacity:$opacity;
width:100%;
text-align:center;
padding-top:15px;
height:50px;
font-family: 'Raleway', sans-serif;
right: 0;
bottom: 0;
left: 0;
position:fixed; 
</pre>";

}


// Generate eveything by one click

if(isset($_POST['submit']))
{
footerPreview();
rawHead();
rawBody();
rawCSS();
}

?>

What I'm trying to achieve is when i click on submit the script should be loaded in the same page without going to a new page or refreshing but still be submitted.

I tried this but it's not the way to go:

<script>
        $.ajax({
        url: 'script.php',
        data: {                 
        },
        type: 'post',

        success: function(output) {


         }
        });
</script>

Edit

Here is my new code:

<!DOCTYPE html>
<html>

    <meta charset="utf-8">

            cache: false,
            contentType: false,
            processData: false
            });
            return false;
          });

        </script>

Answer

Solution:

Check this way,

Arrange your HTML form as this way,

 <form id="myForm" action="" method="post">
    <!-- input fields -->
    <button class="form-control" id="run" type="submit" name="submit">Generate footer</button>
 </form>

And jQuery script,

<script type="text/javascript">
    $('#run').on("click", function (e) {
        var formData = new FormData($('#myForm')[0]);
        $.ajax({
            url: "php_script_page.php",
            type: 'POST',
            data: formData,
            success: function (data) {
                $('#showData').html(data);
            },
            cache: false,
            contentType: false,
            processData: false
        });
        return false;
    });
</script>

Section that you use to show requested content,

<div id="showData">&nbsp;</div>

Add this into php_script_page.php and check how is working 

<?php
    echo "<pre>";
    print_r($_POST);
    echo "</pre>";
?>
