Keadaan saya sangat sukar.
Saya sedang membina klon senarai kelahiran menggunakan pengikis, tetapi saya mengalami kesukaran mengekodkannya kerana saya tidak berpengalaman. Saya berjaya mencipta halaman pentadbir dengan berbilang borang untuk memasukkan tapak, kategori dan borang pautan di mana anda boleh menentukan pautan mana yang harus dirangkak dan ke tapak dan kategori mana ia akan dipautkan. Walaubagaimanapun, tambah macam ni boleh, tapi padam tak boleh..
Tapak, kategori dan pautan saya dipaparkan pada halaman pentadbir saya, dengan butang ambil dan padam untuk setiap elemen. Apabila saya memadamkan item terakhir dalam baris, ia memadamkan elemen pertama. Apabila saya ingin memadam sesuatu yang lain, laravel membuang pengecualian dan ia cuba membaca harta itu pada null yang bermaksud ia tidak wujud lagi. Apabila saya membuang sebelum mengalih keluar fungsi dan mati, setiap item dalam setiap senarai mempunyai id "1". Itulah sebabnya ia memadamkan item pertama berturut-turut. Bolehkah sesiapa membantu saya?
Saya rasa ini kerana id yang meminta untuk memadam item itu diambil dari url dan id yang diberikan dalam url adalah id pengguna iaitu 1. Jadi jika sesiapa boleh memberi saya petunjuk untuk memastikan saya boleh memberikan ID pengguna dengan cara yang berbeza. beritahu saya!
