Question

我有一个涉及BETWEEN语句的查询，无法查看如何为其绑定参数：

 try {
 include("../epsadmin/connectpdo.php");
 $sql="SELECT * FROM properties 
 WHERE location LIKE :location
 AND bedrooms LIKE :bedrooms
 AND category LIKE :category
 AND price BETWEEN :minPrice and :maxPrice 
 ORDER BY postcode";

$stmt = $pdo->prepare($sql);
$stmt->bindParam(':location', $_REQUEST['location'], PDO::STR);
$stmt->bindParam(':bedrooms', $_REQUEST['bedrooms'], PDO::STR);
$stmt->bindParam(':category', $_REQUEST['category'], PDO::STR);
//bindParam for price BETWEEN minPrice and MaxPrice needed
$stmt->execute();
$total = $stmt->rowCount();
$obj = $stmt->fetchObject();
}//end try 
catch(PDOException $error) {
$send='DB Query failed: ' . $error->getMessage(); 
header("Content-type: text/plain");
echo $send;
exit;
}

有人可以帮助处理所需的bindParam声明吗？

如何为涉及BETWEEN语句的查询执行预准备语句

与任何其他查询完全相同：向查询添加必要的占位符，然后使用bindParam方法绑定它们。

MySQL BETWEEN与PDO准备好的语句
