Magento – Add Top Links on condition basis in magento

blockslayoutmagento-1.7

I am little bit stuck with adding top links in my custom phtml. I removed the links block in my XML <remove name="top.links"/>, now after some condition become true, I want to add this block again. When I use this code for top menu it works but not for links :

$block = Mage::getSingleton('core/layout');     
echo $block->createBlock('catalog/navigation')->setTemplate('catalog/navigation/top.phtml')->toHtml();

This works and display top menu. But the below code doesn't show anything.

$block = Mage::getSingleton('core/layout');
echo $block->createBlock('page/template_links')->setTemplate('page/template/links.phtml')->toHtml();

Any help?

The second piece of code actually works but it does not display anything because there are no links attached to the block.
page/template/links.phtml starts with this:

<?php $_links = $this->getLinks(); ?>
<?php if(count($_links)>0): ?>

If there are no links there is nothing to display. You need to add links to your block. Something like this:

$block = Mage::app()->getLayout()->createBlock('page/template_links');
$title = $label = Mage::helper('customer')->__('My Account');
$url = Mage::helper('customer')->getAccountUrl();
$prepareUrl = false;
$urlParams = array();
$position = 10;
$liParams=null;
$aParams=null;
$beforeText=''; 
$afterText='';
$block->addLink($label, $url, $title, $prepareUrl, $urlParams, $position, $liParams, $aParams, $beforeText, $afterText);
//add more links here
echo $block->setTemplate('page/template/links.phtml')->toHtml();

Not all parameters are mandatory for the addLink method. I just added them here so you can see all the possibilities. For more info take a look at this method: Mage_Page_Block_Template_Links::addLink().

Magento – How to edit navigation bar’s html

Since the template does nothing but call the block method (getMenuHtml()) to render the HTML, you might be best off to just replace the navigation template with your own block and template that does what you wish. By doing this you isolate any changes from default into their own files/module and you avoid having to rewrite core files.

There are a million ways to do a better job than the core team when it comes to this specific block. Giving someone a template that does nothing but call a method that renders unseen HTML is hardly even a template in the first place. Just replace it.

Magento 1.7 – Fix Currency ‘USD’ Not Found Error

Ok so I am not sure if this is the bug but if you compare the Magento 1.8 and Magento 1.7 versions of the function currency in Mage_Core_Model_Local you will notice a reference to a bug with Zend_Currency

Magento 1.7: Mage_Core_Model_Local->currency

/**
 * Create Zend_Currency object for current locale
 *
 * @param   string $currency
 * @return  Zend_Currency
 */
public function currency($currency)
{
    Varien_Profiler::start('locale/currency');
    if (!isset(self::$_currencyCache[$this->getLocaleCode()][$currency])) {
        try {
            $currencyObject = new Zend_Currency($currency, $this->getLocale());
        } catch (Exception $e) {
            $currencyObject = new Zend_Currency($this->getCurrency(), $this->getLocale());
            $options = array(
                    'name'      => $currency,
                    'currency'  => $currency,
                    'symbol'    => $currency
            );
            $currencyObject->setFormat($options);
        }

        self::$_currencyCache[$this->getLocaleCode()][$currency] = $currencyObject;
    }
    Varien_Profiler::stop('locale/currency');
    return self::$_currencyCache[$this->getLocaleCode()][$currency];
}

Magento 1.8: Mage_Core_Model_Local->currency

/**
 * Create Zend_Currency object for current locale
 *
 * @param   string $currency
 * @return  Zend_Currency
 */
public function currency($currency)
{
    Varien_Profiler::start('locale/currency');
    if (!isset(self::$_currencyCache[$this->getLocaleCode()][$currency])) {
        $options = array();
        try {
            $currencyObject = new Zend_Currency($currency, $this->getLocale());
        } catch (Exception $e) {
            /**
             * catch specific exceptions like "Currency 'USD' not found"
             * - back end falls with specific locals as Malaysia and etc.
             *
             * as we can see from Zend framework ticket
             * http://framework.zend.com/issues/browse/ZF-10038
             * zend team is not going to change it behaviour in the near time
             */
            $currencyObject = new Zend_Currency($currency);
            $options['name'] = $currency;
            $options['currency'] = $currency;
            $options['symbol'] = $currency;
        }

        $options = new Varien_Object($options);
        Mage::dispatchEvent('currency_display_options_forming', array(
            'currency_options' => $options,
            'base_code' => $currency
        ));

        $currencyObject->setFormat($options->toArray());
        self::$_currencyCache[$this->getLocaleCode()][$currency] = $currencyObject;
    }
    Varien_Profiler::stop('locale/currency');
    return self::$_currencyCache[$this->getLocaleCode()][$currency];
}

My suggestion would be to try updating the try catch to match that of Magento 1.8 (I know this is not the best solution and obviously I would not suggest editing the core files but adding a rewrite)
