    upload_max_filesize<\/code>, PHP’nin kabul edece\u011fi tek bir y\u00fcklenen dosyan\u0131n azami boyutunu belirler. post_max_size<\/code> ise b\u00fct\u00fcn POST iste\u011fini; y\u00fcklenen t\u00fcm dosyalar\u0131, metin alanlar\u0131n\u0131 ve multipart kodlama ek y\u00fck\u00fcn\u00fc kapsar.<\/p>\n

B\u00f6yle bir durumda PHP, WordPress form alanlar\u0131n\u0131 i\u015flemeden \u00f6nce g\u00f6vdeyi reddedebilir veya bo\u015f POST verisi g\u00f6r\u00fclebilir.<\/p>\n
