Introduction

When working with shortcodes in WordPress, it's not uncommon to encounter issues with displaying functions inside these tags. In this article, we'll explore the common problems and provide a comprehensive guide on how to display a function inside shortcode tags.

Understanding Shortcodes

Before we dive into the solution, let's quickly review what shortcodes are and how they work. Shortcodes are a way to add functionality to your WordPress content without writing custom code. They are typically used to display complex content, such as galleries, sliders, or custom widgets.

The Problem: Displaying a Function Outside Shortcode Tags

You've written a function that you want to display inside shortcode tags, but it's displaying outside the tags instead. This can be frustrating, especially when you're trying to create a custom shortcode.

The Solution: Using the do_shortcode Function

The do_shortcode function is a built-in WordPress function that allows you to execute shortcodes within your code. To display a function inside shortcode tags, you can use the do_shortcode function to wrap your function inside the shortcode tags.

Here's an example of how you can use the do_shortcode function to display a function inside shortcode tags:

function myFunction() {
    // Your function code here
    echo 'This is my function';
}

function myShortcode() {
// Use the do_shortcode function to wrap the function inside shortcode tags
echo do_shortcode('[my_function]');
}


// Add the shortcode to the WordPress hook
add_shortcode('my_function', 'myFunction');

In this example, the myFunction function is wrapped inside the do_shortcode function, which is then wrapped inside the shortcode tags [my_function]. When the shortcode is executed, the myFunction function will be displayed inside the shortcode tags.

Using the apply_filters Function

Another way to display a function inside shortcode tags is to use the apply_filters function. This function allows you to filter the output of a function and display it inside shortcode tags.

Here's an example of how you can use the apply_filters function to display a function inside shortcode tags:

function myFunction() {
    // Your function code here
    echo 'This is my function';
}

function myShortcode() {
// Use the apply_filters function to filter the output of the function
echo apply_filters('my_function', 'This is my function');
}


// Add the shortcode to the WordPress hook
add_shortcode('my_function', 'myShortcode');

In this example, the myFunction function is filtered using the apply_filters function, which is then wrapped inside the shortcode tags [my_function]. When the shortcode is executed, the filtered output of the myFunction function will be displayed inside the shortcode tags.
