Laraveli tuumaks on mitu lahedat funktsiooni. M\u00f5ned neist on ringh\u00e4\u00e4ling, failide salvestamine, teatised, s\u00fcndmused jne. K\u00f5ik need sisseehitatud funktsioonid aitavad arendajatel lihtsustada tavalisi ja keerulisi \u00fclesandeid.<\/p>\n

Selles artiklis k\u00e4sitleme Laraveli s\u00fcndmusi, mis v\u00f5imaldavad meil kuulaja registreerida rakenduses esinevate konkreetsete s\u00fcndmuste jaoks. Teisis\u00f5nu v\u00f5in \u00f6elda, et kasutaja on registreerunud, tellimus tehtud, toode lisatud, k\u00f5ik need on s\u00fcndmused. Ja kui peate p\u00e4rast neid s\u00fcndmusi m\u00f5ne toimingu k\u00e4ivitama, saate kuulajad registreerida. Laravel helistab konkreetsetele \u00fcritustele registreerunud kuulajatele automaatselt.<\/p>\n

Meie artikli jaoks rakendan kasutaja registreerimise \u00fcrituse. Kui kasutaja on rakendusse registreerunud, peaks s\u00fcsteem saatma talle tervitusmeili. Siin on kasutajate registreerimine s\u00fcndmus ja tervitusmeili saatmine on kuulaja.<\/p>\n

Seda \u00f6eldes vaatame, kuidas kasutada s\u00fcndmusi ja kuulajaid oma Laraveli rakenduses.<\/p>\n

S\u00fcndmuste ja kuulajate registreerimine Laravelis<\/h3>\n

Laravel pakub EventServiceProvider<\/code>faili, kuhu peate oma s\u00fcndmused ja kuulajad registreerima. Meie puhul peame kasutajate registreerimiseks lisama s\u00fcndmuse ja kuulaja. Niisiis, avage fail EventServiceProvider.php<\/code>ja lisage sinna UserRegistered<\/code>s\u00fcndmus.<\/p>\n
