Javascript and ajax code for price

<script>

function updateFieldPrice(product_id)
        {
            var priceId = '#price_'+ product_id;
            var valueId = '#valueprice_'+ product_id;
            var updatedqty = '#updatedprice_'+ product_id;


            var editLink = "#price_edit_link_"+ product_id;
            var updateButton = "#price_update_button_"+ product_id;
            var resetButton = "#price_reset_button"+ product_id;
            var url ='<?php echo Mage::getUrl('marketplace/marketplaceaccount/updateFieldPrice/')?>';

            $wk_jq(priceId).toggle()

            $wk_jq(editLink).hide();
            $wk_jq(updateButton).show();
            $wk_jq(resetButton).show();

            $price = $wk_jq(priceId).val();
            jQuery(valueId).html($price);
            hideReset(product_id);

            new Ajax.Request(url, {
                method: 'post',
                parameters: {id: product_id, price: $price},
                onComplete: function (transport) {
                    //alert(transport.responseText);

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

                    $updateButton.prop('disabled', false);

                    $wk_jq(priceId).setValue($price);



                }
            });
        }
        function updateAllFields(product_id) {
            updateFieldPrice(product_id);
            updateField(product_id);
            }
    </script>

Javascript and ajax code for special price

function updateFieldSpecialPrice(product_id)
        {

            jQuery(valueId).html($price);
            hideReset(product_id);

            new Ajax.Request(url, {
                method: 'post',
                parameters: {id: product_id, price: $price},
                onComplete: function (transport) {
                    //alert(transport.responseText);

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

                    $updateButton.prop('disabled', false);

                    $wk_jq(priceId).setValue($price);



                }
            });
        }

Answer 1

add this whole code for updating the special price.

$product->setSpecialPrice($upd_price);
 $product->setSpecialFromDate(''); 
$product->setSpecialFromDateIsFormated(false); 
$product->setSpecialToDate(''); 

$product->setSpecialToDateIsFormated(false);
