WordPressi vidina katlaplaat: \u00fcmbert\u00f6\u00f6tamine, 7. osa<\/h2>\n
Need, kes on WordPressi vidinate API<\/a> -ga tuttavad, teavad t\u00f5en\u00e4oliselt, et see pole viimastel aastatel palju muutunud.<\/p>\n Lisaks koosneb see tegelikult ainult neljast funktsioonist (millest \u00fcks on konstruktor):<\/p>\n Tore on see, et see konkreetne l\u00e4henemine saavutatakse WP_Widget<\/a> klassi funktsionaalsuse p\u00e4rimisega.<\/p>\n Probleem on aga selles, et \u00fche klassi jaoks on see palju t\u00f6\u00f6d.<\/p>\n Selle asemel peaksime eraldama k\u00f5ik funktsioonid oma funktsionaalsusaladeks.<\/p>\n Nagu iga programmeerimise puhul, on ka viise, kuidas m\u00f5ned asjad on selged, kuidas neid saab teha, ja siis on asju, mida saab teha mitmel viisil.<\/p>\n Esitan seda, kuidas ma praegu sellele l\u00e4henen. See v\u00f5ib tulevikus muutuda v\u00f5i v\u00f5ib-olla mitte ja teistel v\u00f5ib see olla erinev.<\/p>\n Sellest hoolimata on rakendamine palju rohkem objektorienteeritud ja annab igale klassile oma kohustused.<\/p>\n Esimene k\u00fcsimus on aga, kuidas jagada nelja funktsiooniga klass, mis p\u00e4rib \u00fclemklassilt?<\/p>\n Esiteks peame pistikprogrammi alglaadimisribas kohandama m\u00f5nda asja. Nimelt peame tegema j\u00e4rgmist:<\/p>\n Siin on \u00fclevaade k\u00f5igist kolmest \u00fclaltoodust.<\/p>\n Kuna oleme seda juba sarjas varem k\u00e4sitlenud, peaks olema selge, kuidas seda teha.<\/p>\n Esiteks vaadake j\u00e4rgmist koodi<\/a> :<\/p>\n J\u00e4rgmisena pange t\u00e4hele, et me loome registri (r\u00e4\u00e4gime hetkeks selle nimeruumist) ja \u00fchendame selle kohandatud filtriga, mis v\u00f5imaldab meil sellele pistikprogrammis igal ajal juurde p\u00e4\u00e4seda.<\/p>\n J\u00e4rgmisena peame v\u00e4rskendama pistikprogrammi p\u00f5hiklassi (mis asub\u00a0 kataloogis src<\/strong> ), et see viitaks registrile ja laadiks k\u00f5ik registreeritud abonendid<\/a> :<\/p>\n Pange t\u00e4hele, et me pole veel \u00fchtegi tellijat loonud. Alustasime seda sarja varem ja n\u00fc\u00fcd on aeg selle juurde tagasi tulla, kuid teeme seda hiljem.<\/p>\n Peame siiski lisama funktsiooni<\/a> \u2013 isegi kui see on ajutine \u2013, et saaksime lisada klasse, mis ei ole konkreetse s\u00fcndmuse tellijad:<\/p>\n Seda muudetakse hiljem, kuna muudame p\u00f5hiklassid hiljem tellijateks.<\/p>\n Enne edasiminekut on minu arvates oluline alglaadimisseade \u00fcle vaadata. Kuigi teie p\u00e4is ja dokumentatsioon v\u00f5ivad erineda, on oluline meeles pidada, et teeme j\u00e4rgmist.<\/p>\n See k\u00f5lab palju, kuid kood on \u00fcsna l\u00fchike<\/a> :<\/p>\n Siinkohal on aga aeg vaadata, mis tunne on jagada alamklass tavalisest vidinate API<\/a> -st millekski, mis sobib meie kasutatava koodimudeliga.<\/p>\n See osa h\u00f5lmab t\u00f5en\u00e4oliselt m\u00f5nda postitust, kuna seal on veel natuke t\u00f6\u00f6d teha, kuid alustame oma vidinaklassi loomisega, mis p\u00e4rib p\u00f5hividinate klassist.<\/p>\n K\u00f5igepealt tehke src kataloogis<\/strong> API<\/strong> kataloog ja lisage fail nimega Widget.php<\/strong>. See on koht, kus asuvad vidina p\u00f5hit\u00f5ed. J\u00e4rgmises postituses k\u00e4sitleme administratiivseid ja avalikke laaditabeleid ning JavaScripti faile.<\/p>\n Siinkohal peaksid faili p\u00f5hit\u00f5ed v\u00e4lja n\u00e4gema j\u00e4rgmised<\/a> :<\/p>\n Pange t\u00e4hele, et selleks on vaja \u00fchte argumenti. Olen kasutanud vidina nimi, kuid v\u00f5ite kasutada mida iganes soovite, kui see t\u00e4histab teie vidinat.<\/p>\n Selle eesm\u00e4rk on n\u00e4idata, et klass on pistikprogrammi aktiveerimisel \u00f5igesti instantseeritud ja laaditud. Kui te seda ei n\u00e4e, siis on midagi valesti (selle vaatame kohe \u00fcle).<\/p>\n J\u00e4rgmiseks on oluline veenduda, et see klass on registrisse lisatud. Seega lisage alglaadimisriba j\u00e4rgmised koodiread:<\/a><\/p>\n Ja n\u00fc\u00fcd, kui aktiveerite pistikprogrammi, peaksite n\u00e4gema j\u00e4rgmist:<\/p>\n\n
