Hello Readers, Here is small example which will explain how to hide prices and ‘Add to Cart’ buttons for non-logged users in Magento.

Hide prices in all pages:
Go to Current theme (Path: app/design/frontend/currenttheme/default/template/catalog/product/price.phtml )
Now, open price.phtml
Copy the below code & paste it on top of price.phtml file:

<?php
if(!Mage::getSingleton('customer/session')->isLoggedIn()){
echo '<span class="login_for_price"><strong>Login to See Price</strong></span><br>';
return;
}
?>

above code will hide the price details for unregistered users/non-logged in visitors.

Hide the ‘Add to Cart’ button on product list page
Go to /app/design/frontend/currenttheme/default/template/catalog/product/list.phtml & search for the following code.

Replace It

<?php if($_product->isSaleable()): ?>
<button type="button" title="<?php echo $this->__('Add to Cart') ?>" class="button btn-cart" onclick="setLocation('<?php echo $this->getAddToCartUrl($_product) ?>')"><span><span><?php echo $this->__('Add to Cart') ?></span></span></button><br>
<?php else: ?>
<p class="availability out-of-stock"><span><?php echo $this->__('Out of stock') ?></span></p>
<?php endif; ?>

 with:

<?php
if(!Mage::getSingleton('customer/session')->isLoggedIn()){
echo '<span class="login_for_details" style="float:left"><strong>Login to Add to Cart</strong></span>';
}
else{
?>
<?php if($_product->isSaleable()): ?>
<button type="button" title="<?php echo $this->__('Add to Cart') ?>" class="button btn-cart" onclick="setLocation('<?php echo $this->getAddToCartUrl($_product) ?>')"><span><span><?php echo $this->__('Add to Cart') ?></span></span></button><br>
<?php else: ?>
<p class="availability out-of-stock"><span><?php echo $this->__('Out of stock') ?></span></p>
<?php endif; ?>
<?php    }?>

above code will hide the price details on List/category page for unregistered users/non-login users.
