WP_HTML_Tag_Processor::has_self_closing_flag(): bool

In this article

Indicates if the currently matched tag contains the self-closing flag.

Description

No HTML elements ought to have the self-closing flag and for those, the self-closing flag will be ignored. For void elements this is benign because they "self close" automatically. For non-void HTML elements though problems will appear if someone intends to use a self-closing element in place of that element with an empty body.
For HTML foreign elements and custom elements the self-closing flag determines if they self-close or not.

This function does not determine if a tag is self-closing, but only if the self-closing flag is present in the syntax.

Return

bool Whether the currently matched tag contains the self-closing flag.
