Photo Directory: Store every submitted field as text - #873
Conversation
The submit form's free-text fields are plain text: the description is the photo's alternative text, and the form says so. Only the description was being sanitized, and only when the request declared the photo post type, which the request supplies. Sanitize the title and excerpt alongside it, for every submission, and strip shortcodes as well as markup. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

🟡 Changes recommended
post_title/post_excerpt are currently sanitized with sanitize_textarea_field(), which is more permissive than needed and can preserve unexpected newlines in single-line fields.

Pull request overview
This PR hardens intake sanitization for Photo Directory submissions by ensuring all submitted free-text post fields are stored as plain text (and not as markup/shortcodes), regardless of the user-supplied post_type value.
Changes:
- Sanitize
post_title,post_content, andpost_excerptin thefu_before_create_postpayload (instead of onlypost_content). - Apply the sanitization unconditionally (removing the trust on a request-supplied
post_typegate). - Strip shortcodes from the submitted values before storing.

sanitize_textarea_field() preserves line breaks, which the description wants as the photo's alternative text but the title and excerpt do not. Sanitize those two with sanitize_text_field() instead. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

🔵 Needs a closer look
The current implementation sanitizes post_title/post_excerpt with sanitize_textarea_field(), which can preserve newlines and store unexpected formatting in single-line fields.

Make the sanitizer callable to PHPStan.
The configured PHPStan run reports callable.nonCallable at Line 501 because $fields stores function names as strings. Store closures in $fields, or use an explicit field-specific branch.

The photo submit form's free-text fields are plain text. The description is the photo's alternative text — the form says "No HTML" and caps it at 350 characters — and
sanitize_submitted_description()has stored it as such since 9fc0f0a.Two gaps in that:
post_contentwas sanitized. The title and excerpt travel through the samefu_before_create_postpayload and are stored as they arrive.Sanitize all three fields for every submission, and strip shortcodes as well as markup — shortcode syntax uses none of the characters
sanitize_textarea_field()acts on, so it survives unchanged.Complements #860, which renders the stored description as text. This is the intake side; that is the output side, and it also covers photos submitted before either.
