多个AND，OR语句

Question

您好我想知道以下代码是否可以使用另一个'AND'，'OR'语句进行扩展，还是需要另一个'IF'语句？

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

我试过：

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

但那不起作用。

//更新：

所以这段代码与AJAX一起工作。如果单击该复选框，则会更新页面并过滤选项。我想在多个语句上过滤它而不只是1（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";
        }

您应该使用$where .= " AND (juliette_geinformeerd = 1 " . "OR juliette_geinformeerd = 2)";
