“Hentikan Pemrosesan Aturan Lebih Lanjut” tidak berlaku untuk semua item

Tampaknya ada bug dengan "Hentikan Pemrosesan Aturan Lebih Lanjut" di Magento CE1.9 / EE1.13 di mana hanya item pertama di keranjang Anda yang menerima diskon.

Saya berharap: Jika saya memiliki beberapa aturan keranjang belanja, yang masing-masing memiliki "Hentikan Pemrosesan Aturan Lebih Lanjut: Ya", hanya yang pertama dari aturan ini yang akan diterapkan, namun itu akan diterapkan secara penuh ke semua item yang cocok untuk aturan itu.

Apa yang terjadi: Diskon hanya diterapkan ke item pertama dalam troli, setelah itu pemrosesan aturan dihentikan.

Lihat tangkapan layar: Diskon yang saya harapkan untuk seluruh keranjang adalah $ 50, tetapi karena "Hentikan Pemrosesan Aturan Lebih Lanjut" Saya hanya melihat $ 25.

Saya pikir ini bisa jadi karena _calculator secara efektif disimpan sebagai singleton dalam kelas Mage_SalesRule_Model_Quote_Discount, artinya item kedua yang akan diproses akan mencapai $ this -> _ stopF FurtherRules == true dan bail.

Proses pemikiran saya adalah menyimpan ID aturan $ yang OK untuk diproses, memungkinkan item selanjutnya hanya memproses aturan ini.

Sesuai CE1.9.0.1 dan EE1.14.0.1

Mage_SalesRule_Model_Validator baris 316

- if ($this->_stopFurtherRules) {
+ if ($this->_stopFurtherRules !== false && $rule->getId() != $this->_stopFurtherRules) {

Mage_SalesRule_Model_Validator baris 514

- $this->_stopFurtherRules = true;
+ $this->_stopFurtherRules = $rule->getId();

Ini adalah solusi yang saya usulkan, saya akan tertarik mendengar alasan mengapa ini adalah ide yang buruk!

Apa yang berhasil bagi saya adalah menyetel ulang hentikan tanda aturan selanjutnya setelah setiap item diproses untuk memungkinkan item berikutnya memeriksa aturan yang menentangnya.

tambahkan baris ini:

$this->_stopFurtherRules = false;

langsung setelah loop ini dalam process()metode:

foreach ($this->_getRules() as $rule) {
    ...
}

Itu sesuai 518untuk saya.

Menurut pendapat saya, Magento memiliki back-to-front. Itu item iterates, maka aturan untuk setiap item. Seharusnya iterasi aturan, maka item, sehingga aturan dapat berlaku untuk seluruh keranjang dan hanya kemudian mencegah diskon lebih lanjut.

Ini diperbaiki dalam versi Magento CE yang lebih baru. Di 1.9.2.1 Anda dapat menemukan solusinya, tetapi mungkin sudah diperbaiki lebih cepat.

Kode aslinya terlihat seperti ini:

$appliedRuleIds = array();
foreach ($this->_getRules() as $rule) {
    if ($this->_stopFurtherRules) {
        break;
    }

Dan kode tetapnya harus:

$appliedRuleIds = array();
$this->_stopFurtherRules = false;
foreach ($this->_getRules() as $rule) {
    // The if-clause is removed
    ...    

Perbedaannya adalah $this->_stopFurtherRules = false;danif ($this->_stopFurtherRules) {...}

Tidak ada lagi.

Atau, jika Anda berada di 1.9 Anda dapat dengan mudah mengganti seluruh file tanpa bahaya.

Semoga ini bisa membantu seseorang.

Untuk semua yang perlu memperbaiki masalah itu, harus menimpa metode proses untuk kelas Mage_SalesRule_Model_Validator menjadi seperti di bawah ini
