Beginners Guide To Conditional Tags in WooCommerce and WordPress

Introduction

The Conditional Tags allows the developers to manage what and how the content is displayed on their website. Whether you are developing a theme for WordPres or WooCommerce store, it is great to use these conditional tags to avoid complicated checks in your code. Using the boolean (True/False) conditions, it becomes super easy to display the data you want. The function names are easy to remember. For instance, you can set conditions in your code to show different content according to the device used by the visitor.

In this short guide, you can find the entire set of conditional tags and how to use them in your code.

Understanding the PHP ‘If’ Statements

The PHP ‘If’ statements are used for verifying conditional statements for True (1) and False (0) results. The ‘elseif’ allows the developers to use additional statements. The ‘else’ option will be executed, if the prior statement result is false.

Conditional tags for WordPress

if ( is_page_template( 'about.php' ) {
  echo 'You are currently on about.php template';
} elseif ( is_front_page() ) {
  echo 'You are on front page.';
} else {
  echo 'Not a front page and not about.php template page.';
}

This function helps you to find whether you are currently on a template page you’re checking. You need to specify the teplate name you want to check within the brackets.

In the abovementioned example, if the user is on ‘about.php’ template page, the result will show true. When the condition on the ‘if’ statement is found false, it will verify the ‘elseif’ statement. If the user is not on the ‘Front page’, then the ‘else’ statement will be executed.

Checking Multiple Statements

The Conditional tags is also used for checking two or more statements using ‘AND’ / ‘OR’ to find if a certain condition is met or not. Depending on the test outcome it returns the result as TRUE or FALSE. The result either TRUE or FALSE determines what code will take action.
