WCEmailTemplateSelectiveApplier::migrate_woo_email_content_namespace │ private static │ WC 1.0

Walk the merged tree and rewrite every wp:woo/email-content block to the canonical wp:woocommerce/email-content form. Touches the blockName and the wp-block-woo-email-content CSS class in the block's innerHTML and each innerContent segment. The block's attrs and inner content are otherwise preserved.

Targeted to a single known alias by design — this is not a general alias-migration framework. Add new entries here only when a real deprecated→canonical rename ships and we want it auto-migrated on apply.

Method of the class: WCEmailTemplateSelectiveApplier{}

No Hooks.

Returns

Array. array<string, mixed>>

Usage

$result = WCEmailTemplateSelectiveApplier::migrate_woo_email_content_namespace( $blocks, $migrated ): array;
$blocks(array) (required)
.
$migrated(string[]) (required)
Names of aliases that were rewritten (out param, appended to).
