提交表单中的PayPal捐赠按钮表单

Question

I have a need to submit form with specific values by clicking submit button. When clicking submit button I want to be redirected to PayPal where asked for donation. After submitting donation I need to redirect customer back to my website where form with values are submitted and shown to customer. But right now I`m stuck. If I press submit button after paying or canceling donation nothing happens with entered values in my primary form with title and website. My Code looks like this:

---

    <form action="adding.php" method="post" enctype='multipart/form-data'>
        <table>
        <tr>
            <td class="abc">
                <p id="insert">Title:*</p><br>
                <input type="text" name="title" class="abcd"  value="<?php echo $title; ?>" />
            </td>
            <td class="abc">
                <p id="insert">Website:*</p><br>
                <input type="text" name="website" class="abcd" value="<?php echo $website; ?>" />
            </td>
        </tr>
        </table>
        <input type="submit" value="Submit" id="submit" name="submit" />
    </form>

    <?php
        $sql2 = "INSERT INTO `www` (title, website)
        VALUES ('$title', '$website')";
    ?>
    <?php 
        if (isset($_POST['submit'])) {

            $con = mysql_connect("localhost","root","");
            if (!$con){
            exit("Can not connect: " . mysql_error());
        }
        mysql_select_db("www",$con);            
    ?>
    <?php           
    if ((strlen($title) < 3) or (strlen($title) > 15)) {
        echo "<h1 id='top'>Title must be between 3 and 15 characters long!</h1>";
    } else if (filter_var($website, FILTER_VALIDATE_URL) === false) {
        echo("<h1 id='top'>Website: Please enter a valid website to your wish.</h1>");
    }
    else
    {   
        mysql_query($sql2,$con);
        mysql_close($con);

        header("Location:index.php");           
    }
    ?>

Answer 1

first add the database related code in adding.php, where the first form submits the values, and in this form (adding.php), use javascript to submit the paypal donation form

ie call a javascript function on page unload: call_paypal.

function call_paypal() { document.getElementById("paypal_frm").submit();}

< form action="https://www.paypal.com/cgi-bin/webscr" id="paypal_frm" method="post" target="_top" >

< /form >

It's done...
