多個AND，OR語句

Question

您好，我想知道下面的代碼是否可以用另一個'AND'，'OR'語句擴展，還是需要另一個'IF'語句？

if (in_array("juliette_geinformeerd", $opts)){ 
$where .= " AND juliette_geinformeerd = 1 "; 
} 

我tryed：

if (in_array("juliette_geinformeerd", $opts)){ 
$where .= " AND juliette_geinformeerd = 1 " . "OR juliette_geinformeerd = 2"; 
} 

但是，這並不工作。

//更新：

所以這段代碼工作toghether使用AJAX。如果您單擊複選框，則會更新頁面和過濾器選項。我想過濾多條語句而不是1條（是或否）。

Answer 1

if (in_array("juliette_geinformeerd", $opts)){ 
    $where .= " juliette_geinformeerd = 1 " . "OR juliette_geinformeerd = 2"; 
    } 
// if there is a no other conditions in the where if there any condition so try to write like that: 

$where .="('juliette_geinformeerd_else = 1"; 
    if (in_array("juliette_geinformeerd", $opts)){ 
     $where .= "and juliette_geinformeerd = 1) " . "OR juliette_geinformeerd = 2"; 
     }

您應該使用$where .= " AND (juliette_geinformeerd = 1 " . "OR juliette_geinformeerd = 2)";
