Aşağıda, kodun tıklatılan düğmenin kimliğini php sayfasına göndermek için ajax kullanmış olduğum bir html formu var, ama php sayfasına herhangi bir değer alamıyorum, boş gönderiyor. Bu konuda yeni başlayan biriyim ve öğreticilerle çalıştım, hata yaptığımı kimse işaret edebilir mi? aşağıdaki gibiajax tarafından gönderilen php sayfasındaki verilere erişemiyor musunuz?

mesele, hiçbir tanımlayıcı ile id değerini geçiyoruz $.post görüşmesinde.

$.post("code.php", id);

Buna: Bu

Değişim

$.post("code.php", {id: id});

teşekkürler ama çalışmıyor, php tarafında bu değere nasıl erişebileceğinizi söyler misiniz? $ num = (int) $ _ POST [id]; Bu doğru mu yoksa değişiklik yapmak zorunda mıyım? – navs89

$ .post ("code.php", id) değiştirin;

var request = $.ajax({ 
           url: "code.php", 
           type: "POST", 
           data: {id:id}, 
           dataType: "html" 
           }); 



        request.done(function(msg){ 
         alert(msg); 
        }); 

         request.fail(function(jqXHR, textStatus) { 
            alert("Request failed: " + textStatus); 
         });

ile biz Anahtar => değer çiftini göndermek gerekir unutmayın.

Ajax gönderi yönteminize doğrudan geçiş yapıyorsunuz, bu nedenle anahtar eksik ve anahtar kullanarak erişmeye çalışıyorsunuz.

Var params = {id: id}; // birinci Kimlik anahtarı: ikinci kimlik değeridir.

$ .post ("code.php", params);

bu işe yaramadı ... php kodumda bir sorun var mı? – navs89

Parametreler doğru şekilde iletildiyse, konsolun n konsolunda açılabiliyor ol ... –

evet parametreler doğru şekilde iletiliyor. – navs89
