        $udf3 = '';
        $udf4 = '';
        $udf5 = '';

        $fname = $this->input->post('user_name');
        $email = $this->input->post('user_email');


        $data = array(
            'mkey' => $MERCHANT_KEY,
            'tid' => $txnid,
            'MERCHANT_KEY'=>$MERCHANT_KEY,
            'txnid'=>$txnid,
            'SALT'=>$SALT,
//          'hash' => $hash,
            'amount' => $amount,
            'pinfo' => $productinfo,
            'name' => $fname,

Solution

  • Please completely replace your controller function with below codes

    function checkout() 
{

        $MERCHANT_KEY = "enter your test merchant key here";
        $SALT = "enter your test salt here";

        $txnid = substr(hash('sha256', mt_rand() . microtime()), 0, 20);

        $udf1 = '';
        $udf2 = '';
        $udf3 = '';
        $udf4 = '';
        $udf5 = '';
        $amount = $this->input->post('corporate_plan_rate');
        $productinfo = 'test_payment';
        $fname = $this->input->post('user_name');
        $email = $this->input->post('user_email');

        $hashstring = $MERCHANT_KEY . '|' . $txnid . '|' . $amount . '|' . $productinfo . '|'. $fname . '|' . $email .'|'.$udf1.'|' .$udf2.'|' .$udf3.'|'.$udf4.'|'.$udf5.'||||||'. $SALT;

        $hash = strtolower(hash('sha512', $hashstring));

        $data = array(
            'mkey' => $MERCHANT_KEY,
            'tid' => $txnid,
            'hash' => $hash,
            'amount' => $amount,
            'pinfo' => $productinfo,
            'name' => $fname,
            'productinfo'=>$productinfo,
            'mailid' => $email,
            'phoneno' => '9646403748',
        );

        $this->load->view('payu/checkout', $data);
}

    Now completely replace your checkout view file with following codes

    <html>
    <head>
    </head>
    <body>

        <h2>PayU Form</h2>
        <br/>
        <form method="post" name="payuForm" action="https://test.payu.in/_payment">

            <input name="key" type="hidden" value="<?php echo $mkey ?>" />
            <input name="txnid" type="hidden"  value="<?php echo $tid ?>" />
            <input type="hidden" name="hash" value="<?php echo $hash ?>"/>

            <input name="amount" type="hidden" value="<?php echo $amount; ?>" />

            <input name="productinfo" type="hidden" value="<?php echo $pinfo; ?>">

            <input type="hidden" name="service_provider" value="payu_paisa" size="64" />
            <input name="udf1" type="hidden" value="">
            <input name="udf2" type="hidden" value="">
            <input name="udf3" type="hidden" value="">
            <input name="udf4" type="hidden" value="">
            <input name="udf5" type="hidden" value="">

            <input name="firstname" id="firstname" type="hidden" value="<?php echo $name; ?>"/>

            <input name="email" id="email"  type="hidden"  value='<?php echo $mailid; ?>'>

            <input name="phone"   type="hidden"  value="<?php echo $phoneno; ?>">

            <input name="surl" type="hidden" value="<?php echo base_url('payu/success'); ?>" size="64" />
            <input name="furl" type="hidden" value="<?php echo base_url('payu/cancel'); ?>" size="64" />
            <input name="curl" type="hidden" value="<?php echo base_url('payu/cancel'); ?>" />

            <input type="submit" name="submit_form" value="Click Here for Payment" class="btn btn-info btn-block" >
        </form>
    </body>
</html>
