50 przydatnych kodów WordPress cz. 1

Chciałem podzielić się kilkoma „kawałkami kodów” przydatnych przy tworzeniu stron na WordPress-ie
Zbieram je z sieci od kilku lat. Nie gwarantuję że będą działały w obecnej postaci (kopiuję je z moich notatek)
Nie będę rozpisywał się odnośnie ich funkcjonowania i zastosowania gdyż każdy kto choć trochę kojarzy kod od razu będzie widziała jakie ma on zastosowanie i będzie mógł go ponownie zmodyfikować wg. własnych potrzeb 😉
Mam nadzieje że się przydadzą.
