Question

we entered zip code and checked "COD is available or not", now if we click

on other product page, it should remember the zip code that we entered last time & should display message by default.

Just replace your checkdelivery.phtml with below code

<style>
.block-check-delivery .block-title strong {background-image:none; font-size: 11px;}
.block-check-delivery .block-content {padding:0 10px;  }
.block-check-delivery .button {float: right;}
.block-check-delivery input{width: 107px;}
</style>
<div class="block block-list block-check-delivery">
    <div class="block-title">
        <?php $blockLabel = Mage::getStoreConfig('checkdelivery/general/block_title'); ?>
        <strong><span><?php echo $this->__($blockLabel) ?></span></strong>
    </div>
    <div class="block-content" >        
        <br>
            <input name="zipcode" size="17" type="text" id="zipcode" value="<?php echo Mage::getModel('core/cookie')->get('zip'); ?>" maxlength="10" class="input-text" placeholder="<?php echo $this->__('Enter ZIP Code'); ?>"/>
            <button type="button" name="zip-check" title="Check" class="button" id="zip-check" ><span><?php echo $this->__('Check'); ?></span></button>
            <div id="delivery-message"></div>
            <?php $defaultHtml = Mage::getStoreConfig('checkdelivery/general/default_html'); ?>
            <div id="delivery-html"><?php if(Mage::getModel('core/cookie')->get('message')){
    echo Mage::getModel('core/cookie')->get('message');
}
else{
    $defaultHtml; } ?></div>

        <br>        
    </div>
</div>

<script>
    Event.observe('zip-check', 'click', function(event){
        new Ajax.Request("<?php echo $this->getUrl('checkdelivery/index/index') ?>", {
            method: "get",
            parameters: {zipcode : $('zipcode').value },
            onSuccess: function(transport) {
                 var json = transport.responseText.evalJSON();
                 $('delivery-message').update(json.message);                 
                 $('delivery-message').setStyle({ color: json.color});
                 $('delivery-html').update(json.html);  
            }
        });
    });
</script>

And the indexController.php

<?php
class NextBits_CheckDelivery_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction() {

        $zip = $this->getRequest()->getParam('zipcode');
        $pincodearray = array();
        $pindata = Mage::getStoreConfig('checkdelivery/general/pincode');
        $pincodearray = explode(",", $pindata);
        $success = Mage::getStoreConfig('checkdelivery/general/success_messgae');
        $failure = Mage::getStoreConfig('checkdelivery/general/failure_messgae');
        $empty = Mage::getStoreConfig('checkdelivery/general/empty_messgae');
        $successHtml = Mage::getStoreConfig('checkdelivery/general/success_html');
        $failureHtml = Mage::getStoreConfig('checkdelivery/general/failure_html');
        $defaultHtml = Mage::getStoreConfig('checkdelivery/general/default_html');

        $trimedZip = trim($zip);
        $response = array();
        if(isset($trimedZip) && !empty($trimedZip)){
            if (in_array($trimedZip, $pincodearray)) {
                $response['message'] = $success;
                $response['color'] = 'green';
                $response['html'] = $successHtml;

            }else{
                $response['message'] = $failure;
                $response['color'] = 'red';
                $response['html'] = $failureHtml;

            }
        }else{
            $response['message'] = $empty;
            $response['color'] = 'orange';
            $response['html'] = $defaultHtml;
        }

        Mage::getModel('core/cookie')->set('message', $response['message']);
        Mage::getModel('core/cookie')->set('zip', $zip);
        Mage::getModel('core/cookie')->set('html', $response['html']);
        echo json_encode($response);exit;
    }
}

Here i saved the customer entered data on cookie using

 Mage::getModel('core/cookie')->set('message', $response['message']);
    Mage::getModel('core/cookie')->set('color', $response['color']);
    Mage::getModel('core/cookie')->set('html', $response['html']);

And simple retrieve the value using Mage::getModel('core/cookie')->get('message').

Hope this will help you.. Happy learning

Answer 2

You can save your zip code for user's session in your controller checkdelivery/index/index. It will look like this:

Mage::getSingleton('customer/session')->setData('custom_zip_code', $this->getRequest()->getParam('zipcode'));

And get it everywhere during a single user’s session:

$zip = Mage::getSingleton('customer/session')->getData('custom_zip_code');

Answer 3

to store zip code you can use registry like Mage::register('zip-code', $your-data); and on product page you have to use $zip-code= Mage::registry('zip-code'); and then if($zip-code > 0) { echo 'Cash on delivery is available';} and put the value in textbox.
