Question

I have this code that works perfectly. But, after I submit it, I’m redirected to the external website, where results can be seen. Instead, I want the results to be displayed on the same website. I’m open to to all kinds of suggestion!

Answer 1

First line should be:

echo '<form action="' . $_SERVER[PHP_SELF] . '" method="post">

Then above your last line where you echo, put this:

$response = curl_exec($ch);

Also, change your location line to this:

$location = 'http://results.vtu.ac.in/vitavi.php';

—–EDIT—–

I added some code to parse the response for you, final code would be:

<?php

echo '<form action="' . $_SERVER[PHP_SELF] . '" method="post">
<input type="text" name="rid">
<input type="submit" name="submit" value="submit">
</form>';

if(isset($_POST['submit'])&&(!empty($_POST['rid'])))
{
    $location = 'http://results.vtu.ac.in/vitavi.php';

    $userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_VERBOSE, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_URL, $location );

    $post_array = array(
        "rid" => $_POST['rid'],
        "submit" => "submit"
    );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_array); 
    $response = curl_exec($ch);

    $start = '<TD width="513">';
    $end = '<br>';

    $response = strstr($response, $start);
    $end = stripos($response, $end);
    $response = substr($response, strlen($start), $end - strlen($start));

    echo $response."<br/>";
}  

?>
