*/
// Function to display the Age Calculator Tool
function age_calculator_tool_shortcode() {
ob_start(); // Start output buffering
?>
<div class="container">
<h1>Age Calculator Tool</h1>

<form method="post">
<label for="birthdate">Enter your birthdate:</label>
<input type="date" id="birthdate" name="birthdate" required>
<input type="submit" name="calculate_age" value="Calculate Age">
</form>
<?php
if (isset($_POST['calculate_age'])) {
$birthdate = $_POST['birthdate'];
$current_date = date("Y-m-d");
if (!empty($birthdate) && $birthdate <= $current_date) {
$birthdate_object = new DateTime($birthdate);
$current_date_object = new DateTime($current_date);
// Calculate the difference
$age_difference = $current_date_object->diff($birthdate_object);
// Extract years, months, and days
$years = $age_difference->y;
$months = $age_difference->m;
$days = $age_difference->d;
echo "<div class='result'>You are $years years, $months months, and $days days old.</div>";
} else {
echo "<div class='error'>Please enter a valid birthdate.</div>";
}
}
?>
</div>
<?php
return ob_get_clean(); // Return the output
}
// Register the shortcode [age_calculator_tool]
add_shortcode('age_calculator_tool', 'age_calculator_tool_shortcode');
?>- Activate the Plugin:
- Go to the WordPress Admin Dashboard > Plugins and activate the Age Calculator Tool plugin.
- Add the Shortcode:
- To display the tool on any post or page, use the shortcode:
[age_calculator_tool]
Method 2: Using a PHP Code Execution Plugin
If you don’t want to create a custom plugin, you can use a PHP code execution plugin.
Steps:
- Install a PHP Code Plugin:
- Install and activate the “Insert PHP Code Snippet” plugin (or similar).
- Add the Age Calculator PHP Code:
- Add the PHP code for the Age Calculator as a snippet.
- Use the Shortcode:
- The snippet will generate a shortcode, like
[insert_php_snippet id="1"]. - Insert this shortcode in any post or page to display the calculator.
By following these steps, you can easily integrate the Age Calculator into your WordPress website!
