📝 Creating PHP Shortcode

• Click "Save Code"

💻 Using Shortcodes

📌 Basic Usage

[php_code id="hello_world"]

🎯 Using with Attributes

You can pass custom attributes to your PHP code:

[php_code id="greeting" name="John" age="25" role="admin"]

🔍 Accessing Attributes in Code

There are two ways to access attributes in your PHP code:

1. Direct Variable Access:

echo "Hello $name, you are $age years old";

2. Using Attributes Array:

echo "Role: " . $attributes['role'];

📚 Example with Attributes

1. Create a price calculator:

[php_code id="calculate_price" price="10.99" quantity="3"]

PHP Code:

$total = floatval($price) * intval($quantity);
echo "Total Price: $" . number_format($total, 2);

2. Conditional content:

[php_code id="member_content" role="premium" user="John"]

PHP Code:

if ($role === 'premium') {
    echo "Welcome premium member $user!";
    // Display premium content
}

⚡ Managing Shortcodes

• Click "Edit" to modify the code
• Click "Delete" to remove the shortcode
• Deleted shortcodes will no longer function

💡 Examples

1. Display Text:

echo "Hello World!";

2. Display Date:

echo date("d/m/Y");

3. WordPress Integration:

$posts = get_posts(['numberposts' => 5]);
foreach ($posts as $post) {
    echo '<li>' . esc_html($post->post_title) . '</li>';
}

🛡️ Security Notes

• Always sanitize attribute values before using them
• Use WordPress security functions (esc_html, esc_attr) when outputting data
• Validate numeric values using is_numeric()
• Cast values to appropriate types (intval, floatval)

⚠️ Cautions

• Use esc_html() or esc_attr() functions for security when displaying data
• Avoid using code that may affect website security
• Always test code in a development environment first
