Wie man mehrere Checkbox-Werte in verschiedene Zeilen in die MySQL-Datenbank in Android und PHP einfügt

Question

Hier habe ich Zugriff auf Kontakte vom Telefon und Anzeige in benutzerdefinierten Listenansicht. Nun muss ich die ausgewählten checkbox Werte zu verschiedenen Zeilen mysql Datenbank einfügen.Hier kann ich einzelne Checkbox Wert in die Datenbank einfügen..wenn ich mehr als einen Wert ausgewählt haben, werden die Daten in der einzelnen Zeile gespeichert .. Welche Änderungen muss ich vornehmen, um die einzelnen Daten in jede Zeile einzufügen? Ich verwende eine PHP-Datei, um Daten in der Datenbank zu speichern.

Answer 1

Sie müssen JSON beginnen, Ihre Daten zu halten:

Build it:

HashMap<String,String> param = new HashMap<String,String>(); 
param.put(kcontacts,contacts.toString()); 
return rh.sendPostRequest(UPLOAD_URL, param); 

Endlich:

JSONArray contacts = new JSONArray(); 
for(int i = 0; i < name1.size(); i++) 
{ 
    JSONObject contact = new JSONObject(); 
    contact.put(kname, name1.get(i).toString()); 
    contact.put(kphone, phno1.get(i).toString()); 
    contact.put(kvault,vault_no); 
    contacts.put(contact); 
} 

Dann ist es zu Ihrem hashmap als Parameter übergeben in PHP dekodieren, dass:

$contacts = json_decode($_POST['contacts'], true); 
foreach($contacts as $contact){ 
    echo $contact['name']; 
} 

Answer 2

Verwendung Foreah Post Wertekontrollkästchen.

 $vault_no1= $this->input->post("vault_no"); 
     foreach($vault_no1 as $key=>$val){ 
      $arra[] = $val; 
     } 


     $name= $this->input->post("name"); 
     foreach($name as $key=>$val){ 
      $arre[] = $val; 
     } 


     $phone= $this->input->post("phone"); 
     foreach($phone as $key=>$val){ 
      $arrv[] = $val; 
     } 

     $length = count($arra); 
     for ($i = 0; $i < $length; $i++) { 
      echo "vault_no".$arra[$i]." Name:".$arre[$i]." phone:".$arrv[$i]; //Sample print for you 
      //Use your Insert query here with aboe arrays value 
     }
