MarkupLoom – JSON-LD Manager

تفصیل

MarkupLoom provides a focused interface for adding structured data to individual WordPress content items.

Multiple schemas can be assigned to the same Page, Post, or WooCommerce Product. Enabled individual schemas are combined into a JSON-LD @graph.

The plugin also provides a global schema manager for site-wide rules.

Features

• Multiple schemas per Page, Post, and WooCommerce Product.
• Checkbox-based Post Type selection for global schemas.
• Individual schema controls inside the WordPress editor.
• JSON-LD @graph output for multiple individual schemas.
• Product schema support for WooCommerce.
• Custom JSON-LD support.
• Dynamic placeholders for common WordPress values.
• Global schema rules for the entire site, homepage, singular content, or selected post types.
• Schema type allow-list.
• Nonce and capability checks.
• Safe JSON-LD encoding to prevent script-tag breakout.

Example:

{
"@context”: "https://schema.org”,
"@type”: "WebPage”,

"url”: {{url}},
"description”: {{description}}
}

Quoted full-value placeholders are also supported.

Multiple Schemas

A single content item may contain multiple schemas, such as:

• Product
• BreadcrumbList
• FAQPage

Enabled individual schemas are emitted together in a JSON-LD @graph.

WooCommerce

When WooCommerce is active, Product schema can use:

• Product name
• Description
• URL
• SKU
• Product image
• Price
• Currency
• Stock availability
• Brand
• GTIN
• MPN

Security

MarkupLoom validates custom JSON before storing it and re-encodes schema data with wp_json_encode() and JSON hexadecimal encoding flags before placing it inside a JSON-LD script element.

Administrator-only configuration is protected by WordPress capability and nonce checks.

Compatibility

• WordPress 6.4 or later.
• PHP 7.4 or later.
• WooCommerce is optional.
