Ticket #55358: 55358-term_exists-parent-param.patch

File 55358-term_exists-parent-param.patch, 1.7 KB (added by sachinrajcp123, 4 months ago)

Makes term_exists() respect the $parent parameter ✅ Ensures accurate checks for terms under different parents ✅ Prevents false “term already exists” errors in hierarchical taxonomies ✅ Improves reliability for wp_insert_term() and related functions
