This is How to Grab div Text by Class and Create Shortcode to Display on Search Results Page
As a WordPress developer, you may often find the need to pull specific text or data from a div on your website and display it in a different location. This could be particularly useful for showcasing key information or highlights on your search results page.
However, the process of grabbing div text by class and then creating a shortcode to display that data can be tricky – especially if you're not a seasoned coder. That's why we've put together this comprehensive guide to walk you through the steps.
The Challenge: Pulling Div Text by Class
Let's say you have a webpage with a div that contains important information you want to display on your search results page. The div might look something like this:
<div class="key-info">
<h2>Key Highlights</h2>
<p>This is some important text that we want to display on the search results page.</p>
</div>
The goal is to grab the text content inside that div with the class "key-info" and make it available to display elsewhere on your site.
Traditionally, this would involve writing custom PHP or JavaScript code to target that specific div, extract the text, and then output it where needed. However, this can be time-consuming and requires a decent amount of technical know-how.
The Solution: Creating a Custom Shortcode
To make this process easier, we're going to create a custom WordPress shortcode. This will allow you to simply drop a shortcode into your search results template, and the text from the target div will automatically appear.
Here's how to do it:
Step 1: Define the Shortcode Function
First, you'll need to add the following code to your theme's functions.php file or in a custom plugin:
function display_div_text_by_class($atts) {
// Define the default attributes for the shortcode
$atts = shortcode_atts(array(
'class' => 'key-info'
), $atts);
// Grab the text content from the div with the specified class
$div_text = '';
$div = get_the_content();
if (preg_match('/<div class="' . $atts['class'] . '">(.*?)<\/div>/s', $div, $match)) {
$div_text = $match[1];
}
// Return the div text
return $div_text;
}
add_shortcode('display_div_text', 'display_div_text_by_class');
Here's a breakdown of what's happening:
- The
display_div_text_by_class()
function is defined as the shortcode callback.
- The
shortcode_atts()
function sets the default attribute for the shortcode, which is the class name of the target div ("key-info" in this example).
- The function then uses a regular expression to search the page content (
get_the_content()
) for a div with the specified class and extracts the text content inside.
- Finally, the extracted text is returned as the output of the shortcode.
- The
add_shortcode()
function registers the shortcode with WordPress, making it available for use.
Step 2: Use the Shortcode in Your Search Results Template
Now that the shortcode is defined, you can use it in your search results template (usually located in the search.php
file). Simply add the shortcode where you want the div text to appear:
<div class="search-result">
<h2><?php the_title(); ?></h2>
[display_div_text class="key-info"]
<p><?php the_excerpt(); ?></p>
</div>
In this example, the [display_div_text class="key-info"]
shortcode will be replaced with the text content of the div with the "key-info" class from the original page.
Step 3: Customize the Shortcode Attributes
The shortcode you just created has a single attribute, class
, which allows you to specify the class name of the target div. If you have multiple divs you want to target, you can add additional attributes to the shortcode.
For example, you could modify the shortcode function to accept multiple class names:
function display_div_text_by_class($atts) {
$atts = shortcode_atts(array(
'classes' => 'key-info,another-class'
), $atts);
$classes = explode(',', $atts['classes']);
$div_text = '';
foreach ($classes as $class) {
$class = trim($class);
if (preg_match('/<div class="' . $class . '">(.*?)<\/div>/s', get_the_content(), $match)) {
$div_text .= $match[1] . '<br>';
}
}
return $div_text;
}
add_shortcode('display_div_text', 'display_div_text_by_class');
In this updated version, the classes
attribute accepts a comma-separated list of class names. The function then loops through each class and extracts the text content, concatenating the results and returning them.
You can then use the shortcode like this:
[display_div_text classes="key-info,another-class,third-class"]
This will display the text content of all divs with the specified classes.

Real-World Example and Benefits
Let's consider a real-world example of how this shortcode could be used to enhance your WordPress search results page.
Imagine you have an e-commerce website that sells various products. Each product page contains a "Key Features" section, which is displayed in a div with the class "key-features". You want to ensure that these key features are prominently displayed on the search results page, as this can help users quickly identify relevant products.
Using the custom shortcode you created, you can easily pull the "Key Features" text and display it on the search results page without having to manually copy and paste the content. This not only saves time but also ensures that the information is always up-to-date, as it's dynamically pulled from the original page.
By implementing this solution, you can provide a better user experience for your site visitors, making it easier for them to find the products they're looking for and understand the key features at a glance. This can lead to higher engagement, lower bounce rates, and potentially improved conversion rates.
Additionally, this approach is highly flexible and scalable. If you need to target different sections of your pages, you can simply update the shortcode attributes or create additional shortcodes to suit your needs. This makes it a versatile tool for any WordPress developer looking to enhance their search results pages.
Conclusion
Grabbing div text by class and creating a shortcode to display it on your WordPress search results page is a powerful technique that can improve the user experience and discoverability of your content. By following the steps outlined in this guide, you can easily implement this solution and start showcasing key information to your site visitors.
Remember, the beauty of this approach lies in its simplicity and flexibility. You can customize the shortcode to target different divs, combine multiple sections, and even add additional functionality as needed. So why not give it a try and see how it can benefit your WordPress site?
