Sanitizes a given string in a specific context, particularly for handling HTML content in Paid Memberships Pro (PMPro) emails.
This filter runs after the strings are passed through the core WordPress wp_kses function. The wp_kses function makes sure that only the allowed HTML element names, attribute names, attribute values, and HTML entities will occur in the given text string.
Paid Memberships Pro extends the core WordPress allowed HTML elements using the pmpro_kses_allowed_html() function.
Together, these filters and functions provide control over the allowed HTML content within Paid Memberships Pro frontend pages and emails. The goal is to ensure that content is both safe and appropriate for its context.
apply_filters( 'pmpro_kses', $sanitized_string, $original_string, $context );
Parameters
- $original_string
string; The original string that needs to be sanitized.- $context
string; The context for sanitization. The default value is ’email’.
Return Value
- $sanitized_string
string; The sanitized string after applying the appropriate sanitization based on the context.
