使用Mysql查询where条件

Question

我已经解码了Json，现在想要在数据库中提交，

如何在条件何处使用此查询？

if(is_array($arr)){

    $sql = "INSERT INTO wp_posts (post_title, post_type) values ";

    $valuesArr = array();
    foreach($arr as $row){

        $email = mysql_real_escape_string( $row['property_name'] );
        $post = mysql_real_escape_string( $row['post_type'] );

        $valuesArr[] = "('$email', '$post')";


    }

    $sql .= implode(',', $valuesArr);

    mysql_query($sql) or exit(mysql_error()); 
}

if(is_array($arr)){ $valuesArr = array(); foreach($arr as $row){ $email = mysql_real_escape_string( $row['property_name'] ); $post = mysql_real_escape_string( $row['post_type'] ); $sql = "update wp_posts set post_title='".$email."', post_type='".$post."' where X=Y"; mysql_query($sql) or exit(mysql_error()); } }
