values are not saving after refreshing the page

Question

we are using marketplace multivendor site, so we gave an option for seller to update the product attributes from frontend. now if we update attribute values from backend , its working fine in frontend. but if we try saving in frontend,its not saving in backend.

In frontend, its saving, but after refreshing the page, it show old values..

we are using following code to save values in database :

Phtml

<?php $attribute = $products->getResource()->getAttribute('mp_local_shipping_charge');?>
<?php if($attribute):?>
<?php $attribute_value = $attribute ->getFrontend()->getValue($products); ?>

<input class="ama1" type = "text" id = "local_<?php echo $products->getId(); ?>" onkeydown="validateNumbers(event)" name= "local[]" value = "<?php echo $attribute_value; ?>" style = ""/>
<?php endif; ?>


<input type="hidden" name="localcurr_<?php echo $products->getId(); ?>" id="localcurr_<?php echo $products->getId(); ?>" value="<?php echo $products->getLocal(); ?>" /> 

<p id="updatedlocal_<?php echo $products->getId(); ?>" style = "display:none;color:red; position:relative; top:16px;">Updated</p>
<br/>

<button id="local_reset_button_<?php echo $products->getId(); ?>" type="reset" class="cancel" onclick="hideResetLocal('<?php echo $products->getId(); ?>','<?php echo $products->getPrice(); ?>'); return false;">
<span><span><?php echo $helper->__('Cancel') ?></span></span>
</button>

JS

function hideResetLocal(product_id,localold) { 

var qtyId='#local_'+ product_id; 
var currlocal='#localcurr_'+ product_id; 
var editLink="#local_edit_link_"+ product_id; 
var updateButton="#local_update_button_"+ product_id; 
var valuelocal="#valuelocal_"+ product_id; 
var resetButton="#local_reset_button_"+ product_id; 


$wk_jq(valuelocal).show(); 
$wk_jq(qtyId).val( $wk_jq(currlocal).val()); 
$wk_jq(editLink).show(); 

}



function showFieldLocal(product_id)
        {

            var qtyId='#local_'+ product_id;

            var editLink="#local_edit_link_"+ product_id;
            var valuelocal="#valuelocal_"+ product_id;
            var updateButton="#local_update_button_"+ product_id;
            var resetButton="#local_reset_button_"+ product_id;

            $wk_jq(qtyId).show();
            $wk_jq(valuelocal).hide();

            $wk_jq(editLink).hide();
            $wk_jq(updateButton).show();
            $wk_jq(updateButton).prop('disabled', false);//just in case
            $wk_jq(resetButton).show();

            return false;


        }




function updateFieldLocal(product_id) 
{ 
var localId = '#local_'+ product_id; 
var currlocal='#localcurr_'+ product_id; 
var updatedqty = '#updatedlocal_'+ product_id; 
var url ='<?php echo Mage::getUrl('marketplace/marketplaceaccount/updateFieldLocal/')?>'; 
$local = $wk_jq(localId).val(); 
$wk_jq(currlocal).val($local); 
new Ajax.Request(url, { 
method: 'post', 

parameters: {id: product_id, local: $local}, 
//parameters: {id: product_id, local: $local}, 
onComplete: function (transport) { 
//alert(transport.responseText); 

jQuery(updatedqty).show().delay(2000).fadeOut(); 

} 
}); 
}

Controller.php

 public function updateFieldLocalAction(){
 //   Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID); 

     Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
     $product = Mage::getModel('catalog/product')->load($id);
     $product->setStoreId(Mage::app()->getStore()->getStoreId())->setMpLocalShippingCharge($upd_local)->save();

    $id= $this->getRequest()->getParam('id');

    $collection_product = Mage::getModel('marketplace/product')->getCollection()->addFieldToFilter('mageproductid',array('eq'=>$id))->addFieldToFilter('userid',array('eq'=>$customerid));

    try{
    $upd_local = $this->getRequest()->getParam('local');
     Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
    $product = Mage::getModel('catalog/product')->load($id);
    $product->setStoreId(Mage::app()->getStore()->getStoreId())->setMpLocalShippingCharge($upd_local)->save();


    echo $name = $product->getName();

    $response['message'] = 'Your Product Is Been Sucessfully Updated';
    $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response)); 

    }    

  }

Answer 1

try this one

 $product->setData('mp_local_shipping_charge', $upd_local)
            ->getResource()
            ->saveAttribute($product, 'local');

    $product->save();

or try that

try{
    $upd_local = $this->getRequest()->getParam('local');
     Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
    $product = Mage::getModel('catalog/product')->load($id);
    $product->setStoreId(Mage::app()->getStore()->getStoreId())->setMpLocalShippingCharge($upd_local)->save();


    echo $name = $product->getName();

    $response['message'] = 'Your Product Is Been Sucessfully Updated';
    $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response)); 

    }
