Question

のときだけフィールドがエコー表示されます。画面上の行が開いていないようにするには、5つのvipフィールドにどのように到達できますか？

おかげで、ベニー

$db = new mysqli('host', 'user', 'pass', 'dbase');

    printf("Connect failed: %s\n", mysqli_connect_error());

Answer 1

if(!empty({$row->vip1}) and !empty({$row->vip2}) and !empty({$row->vip3}) and !empty({$row->vip4}) and !empty({$row->vip5})){ 
    echo "{$row->FName} {$row->LName} {$row->HerbalifeID} {$row->pfn} {$row->pln}<br>{$row->vip1}{$row->vip2}{$row->vip3}{$row->vip4}{$row->vip5})<br><br>"; 
}else{ 
    echo "{$row->FName} {$row->LName} {$row->HerbalifeID} {$row->pfn} {$row->pln})<br><br>"; 

}

私はそれを得る場合、私は知りません。 すべてのチップがいっぱいになったときにのみ印刷したい場合は、次のコードを使用してください：

//... 
$range = range(1,5); 
while ($row = $result->fetch_object()) { 

    //This will be printed in every iteration 
    echo "{$row->FName} {$row->LName} {$row->HerbalifeID} {$row->pfn} {$row->pln}"; 

    //if one of the vips has no value, go to the next $row 
    foreach($range as $r){ 
     $vipColumn = "vip$r"; 
     if(empty($row->$vipColumn)){ 
      continue 2; //breaks both 'foreach' and 'while' loops 
     } 
    } 

    //This only echo when all vips has values 
    echo "<br>{$row->vip1}{$row->vip2}{$row->vip3}{$row->vip4}{$row->vip5})<br><br>"; 

} 
//...
