Filter<\/h2>\n

Advanced Custom Fields pakub filtrit nimega [acf\/load_field](https:\/\/www.advancedcustomfields.com\/resources\/acf-load_field\/)<\/code>. Saate seda filtrit kasutada mitmel erineval viisil. Filtreerige acf\/load_field<\/code>, et rakendada see igat t\u00fc\u00fcpi v\u00e4ljadele, v\u00f5i lisage kood oma konksuga funktsiooni sisse, et v\u00e4lja selgitada, millist v\u00e4lja t\u00fc\u00fcpi v\u00f5i nime soovite. V\u00f5i saate m\u00e4\u00e4rata kas v\u00e4lja t\u00fc\u00fcbi (acf\/load_field\/type=<type><\/code>), nime (acf\/load_field\/name=<name><\/code>) v\u00f5i v\u00f5tme (acf\/load_field\/key=<key><\/code>).<\/p>\n

Oletame, et loome tekstiv\u00e4lja j\u00e4rgmiselt:<\/p>\n

V\u00f5iksime seda sihtida acf\/load_field\/name=dyn_pop_example<\/code>(sihib ainult seda konkreetset v\u00e4lja) acf\/load_field\/type=text<\/code>(kehtib k\u00f5ikidele tekstit\u00fc\u00fcpi v\u00e4ljadele) v\u00f5i acf\/load_field<\/code>(kehtib k\u00f5ikidele mis tahes t\u00fc\u00fcpi v\u00f5i nimega v\u00e4ljadele). Kahe viimase filtri kasutamisel saate muidugi funktsiooni sees sihtida konkreetse v\u00e4lja teabe, n\u00e4iteks nime j\u00e4rgi. Iga ACF-i v\u00e4li saab samuti ainulaadse v\u00f5tme, kuid need on peidetud ja on enamasti m\u00f5eldud ACF-i sisekasutuseks.<\/p>\n

Filter annab \u00fche muutuja; v\u00e4lja massiiv. See massiiv annab teile kogu teabe praeguse v\u00e4lja kohta. Te muudate lihtsalt massiivi teavet ja tagastate muudetud v\u00e4lja massiivi. S\u00f5ltuvalt v\u00e4lja t\u00fc\u00fcbist erinevad massiivi elemendid. N\u00e4iteks mitme valikuga v\u00e4ljat\u00fc\u00fcpidel, nagu Select ja Radioboxes, on massiivielement ‘ choices<\/code>‘, mida n\u00e4iteks t\u00fc\u00fcpi tekst v\u00e4ljadel ei ole. Soovitan teil teha var_dump()<\/code>pakutud massiivi, et n\u00e4ha, millisele teabele teil on juurdep\u00e4\u00e4s.<\/p>\n
