It's common practise on eCommerce websites to display information about the contents of the current cart. This article will explain how to code a "current cart".

Current Cart: Number Of Items In Cart

The following snippet of code displays the number of items in the current user's cart. The snippet checks to determine whether there are any items in the cart, if there are no items present in the cart, "No Items in Cart" will be displayed.

<p> <a href="/commerce/order/"> Cart ( <logic:if test="\Components\Commerce\Carts\Current::getCount()"> [? \Components\Commerce\Carts\Current::getCountProducts() ?] </logic:if> <logic:else>No Items in Cart</logic:else> ) </a> </p>

Current Cart: Current Order Total

The following snippet of code displays the total of the current user's cart. The snippet checks to determine whether there are any items in the cart, if there are no items present in the cart, "No Items in Cart" will be displayed.

<p> <a href="/commerce/order/"> Cart ( <logic:if test="\Components\Commerce\Carts\Current::getCount()"> [? \Components\Commerce\Products::renderPrice(\Components\Commerce\Carts\Current::getTotal(), 'strong') ?] </logic:if> <logic:else>No Items in Cart</logic:else> ) </a> </p>

Logic is used to show content based on a test. Repeaters are used to list elements like Products, Pages, or Contacts.

Logic IF

The <logic:if> control performs a test, and renders everything inside the tag if the test is true. The test is defined within the test="true" attribute, and is often an API call.  

The following examples are usually defined in the website design to show content dynamically: 

IF the current visitor is logged in, show "you are logged in".

<logic:if test="\Components\Customers\Contacts::currentIsLoggedIn()"> <p>You are logged in.</p> </logic:if>


IF the current page is the "About Us" page, show a heading.

<logic:if test="\Components\Website\Pages::currentPageId() == '/about-us/'"> <h2>About Us</h2> </logic:if>

Logic ELSE

The <logic:else> control defines an alternate region to show in the case that an IF test fails. Extending the above examples: 

IF the current visitor is logged in, show "you are logged in".
ELSE show "You are not logged in":

<logic:if test="\Components\Customers\Contacts::currentIsLoggedIn()"> <p>You are logged in.</p> </logic:if> <logic:else> <p>You are not logged in.</p> </logic:else>


IF the current page is the "About Us" page, show a heading.
ELSE show a message "Another Page".

<logic:if test="\Components\Website\Pages::currentPageId() == '/about-us/'"> <h2>About Us</h2> </logic:if> <logic:else> <h2>Another Page</h2> </logic:else>


The ELSE tag must be defined after an IF tag. 

You can add additional Else tags with test conditions to be checked if the previous test fails:

<logic:if test="\Components\Website\Pages::currentPageId() == '/about-us/'"> <h2>About Us</h2> </logic:if> <logic:else test="\Components\Website\Pages::currentPageId() == '/services/'"> <h2>Services</h2> </logic:else> <logic:else> <h2>Another Page</h2> </logic:else>

Loops: The Data Repeater Control

<data:repeater> is commonly used to list elements like Products, Pages, or Contacts.

The Data Repeater repeats everything inside the tag, for each item in a given data source.

The "as" attribute defines the name of the variable, and the "datasource" attribute usually defines an API call to retrieve a Page, Product or Contact.

The following example will list all Posts:

<data:repeater as="post" datasource="\Components\Website\Posts::getAll()"> <h1>[? $post['post_title'] ?]</h1> [? $post['post_content_short'] ?]; </data:repeater>


Or, to show all contacts in a specific Group:

<data:repeater as="contact" datasource="\Components\Customers\Groups::getContactsInGroup('/group-id-here/')"> <h1>[? $contact['contact_first_name'] ?]</h1> </data:repeater>

DataLimit and DataStart Attributes 

The DataLimit attribute can be used to limit the number of records displayed. For example, you may wish to only show three Posts: 

<data:repeater as="post" datalimit="3" datasource="\Components\Website\Posts::getAll()"> <h1>[? $post['post_title'] ?]</h1> [? $post['post_content_short'] ?]; </data:repeater>


The DataStart attributes may be used in addition to the DataLimit attribute to show from a record, to a record. As an example, the following code will only show all Posts, starting at the Third Post:

<data:repeater as="post" datastart="2" datasource="\Components\Website\Posts::getAll()"> <h1>[? $post['post_title'] ?]</h1> [? $post['post_content_short'] ?]; </data:repeater>


Note: DataLimit is an array index, so the first record is at index 0:

[0 => "First Post"]
[1 => "Second Post"]
[2 => "Third Post"]

Examples

Else - Syntax

Use ELSE after an IF logic statement. Specify a block of code to be executed if a logic IF test failed.

HTML:

<logic:if test=""> If this logic test passes, this will render. </logic:if> <logic:else test=""> If the first logic test fails, but this second test passes, this will render. </logic:else> <logic:else> If neither of the above tests pass, this will render. </logic:else>

Show a different message when a contact is logged in.

HTML:

<logic:if test="\Components\Customers\Contacts::currentIsLoggedIn()"> Welcome Back! You're logged in. </logic:if> <logic:else> You're not logged in, click here to login. </logic:else>
