Question

我正在尝试运行SQL查询但是我收到以下错误： mysqli_fetch_array（）期望参数1为mysqli_result，boolean given

我的代码：

$pricerange = $_GET['pricerange'];

$ary = explode("-",$pricerange);

$price_min =  filter_var($ary[0], FILTER_SANITIZE_NUMBER_INT);
$price_max =  filter_var($ary[1], FILTER_SANITIZE_NUMBER_INT);

$card_data =  mysqli_query($con, "SELECT * FROM builds WHERE approved = 'yes' WHERE build_price >= '$price_min' AND build_price <= '$price_max'");
$card_data_result = mysqli_fetch_array($card_data);
$pricerange = $_GET['pricerange'];

我已经做了一些关于错误及其错误的研究，因为查询返回false或true（它似乎没有）任何想法如何修复它？

Answer 1

您在选择查询中使用了两个where子句。

试试这个，

 SELECT * FROM builds WHERE approved = 'yes' and  build_price >= '$price_min' AND build_price <= '$price_max'

OR

 SELECT * FROM builds WHERE approved = 'yes' and build_price BETWEEN '$price_min' AND '$price_max'

而不是

 SELECT * FROM builds WHERE approved = 'yes' WHERE build_price >= '$price_min' AND build_price <= '$price_max'

mysqli_fetch_array（）期望参数1为mysqli_result，给定布尔值
