Magento: Enable template block hint in admin panel

You can enable Template path hint in two ways:

WAY 1:

Connet your Database and enter values into ‘core_config_data’ table

Run the following query on the Magento database:

INSERT INTO core_config_data (scope, scope_id, path, value)
VALUES ('default', 0, 'dev/debug/template_hints', 1),
('default', 0, 'dev/debug/template_hints_blocks', 1);

When you’ve finished development want to turn off template hints in the admin panel, open the core_config_data table and change the ‘value’ column of the two row you inserted to “0”.

Way 2 :
open app/code/core/Mage/Core/Block/Template.php and find the function named

function getShowTemplateHints()

change the code with the following code:

  public function getShowTemplateHints()
    {
        if (is_null(self::$_showTemplateHints)) {
            self::$_showTemplateHints = Mage::getStoreConfig(self::XML_PATH_DEBUG_TEMPLATE_HINTS)
                && Mage::helper('core')->isDevAllowed();
            self::$_showTemplateHintsBlocks = Mage::getStoreConfig(self::XML_PATH_DEBUG_TEMPLATE_HINTS_BLOCKS)
                && Mage::helper('core')->isDevAllowed();
        }
        //return self::$_showTemplateHints;
        return true;
    }

Way 3:
Add the following code in local.xml(/app/etc/local.xml)

<!--Start Admin Path Hints -->
<websites>
        <admin>
            <dev>
                <debug>
                    <template_hints>1</template_hints>
                    <template_hints_blocks>1</template_hints_blocks>
                </debug>
            </dev>
        </admin>
</websites>
<!--End Admin Path Hints -->

The above code will enable path link in both admin and frontend
