Kas soovite m\u00e4\u00e4rata esilet\u00f5stetud pildi WordPressi koodi abil? M\u00f5nikord kohtasite \u00fclesannet, kus peate kirjutama koodijupi, mis peaks m\u00e4\u00e4rama postituse pisipildi postituse, lehe v\u00f5i kohandatud postit\u00fc\u00fcpide jaoks. Selles artiklis uurime, kuidas esilet\u00f5stetud pilti WordPressis programmiliselt seada.<\/p>\n

WordPress pakub veebisaitidele palju kasulikke funktsioone. \u00dcks neist on Featured Image aka Post Thumbnail. Esilet\u00f5stetud pilt on postituse, lehe v\u00f5i kohandatud postit\u00fc\u00fcbi t\u00fc\u00fcpiline pilt.<\/p>\n

Regulaarne viis postituse pisipildi seadmiseks<\/h3>\n

Esilet\u00f5stetud pilte saame teatud postitustele v\u00f5i lehtedele \u00fcles laadida, kl\u00f5psates lingil \u201eM\u00e4\u00e4ra esilet\u00f5stetud pilt". See avab WordPressi meedialaadija, kus saate valida olemasoleva pildi v\u00f5i uue pildi \u00fcles laadida.<\/p>\n

\"Kuidas<\/a><\/p>\n

See on lihtne viis WordPressis postituse pisipildi seadmiseks. Lehtede ja postitust\u00fc\u00fcpide puhul tuleb j\u00e4rgida samu samme.<\/p>\n

Kuid nagu alguses mainitud, on selle artikli eesm\u00e4rk kirjutada kood, mis m\u00e4\u00e4rab postituse pisipildi, j\u00e4rgimata \u00fclaltoodud samme.<\/p>\n

Selle \u00f5petuse jaoks koostan vormi, kus kasutaja saab valida pildi ja see pilt m\u00e4\u00e4ratakse postituse pisipildiks m\u00e4\u00e4ratud postituse ID-le. Pange allolev kood mallifaili.<\/p>\n
