Question

我正试图从 services （表名）中获取'price'（列名）的值，以插入下面脚本中的var var。

任何帮助都将不胜感激。

<script type="text/javascript">
    var amount       = '100.00';  //need to insert amount here for each user before making payment
    var currency     = 'USD';   // 
    var discount     = '0.00';//

服务（表格结构） 5列

s_id |名字|价格|折扣|删除

这是我在@Zanderwar评论之后尝试过的。

<?php

include '../with_session.php';
include '../db-connection.php';
session_start();
$id=$_SESSION['id'];

$sid="SELECT s_id WHERE id='$id'";  //to get s_id coloumn value
$resultsid=mysqli_query($con, $sid);
$rowid=mysqli_fetch_assoc($resultsid);


$qamount= "SELECT price FROM services WHERE s_id='.$resultsid'";// selecting price to insert into    amount
$resultq= mysqli_query($con, $qamount);
$row_data = mysqli_fetch_assoc($resultq);

$row_data=$resultq;

?>

    var discount     = '0.00';// Optional Field 
    var title        = 'Test Express Checkout Transaction'; // Title of your transaction 

</script> )

Answer 1

您可以使用PHP回显值，显然需要一个活动的MySQL连接和一个名为$row_data的结果集。

<script type="text/javascript">
    var amount       = '<?=$row_data['amount']?>';  //need to insert amount here for each user before making payment
    var currency     = '<?=$row_data['currency']?>';   // 
    var discount     = '<?=$row_data['discount']?>';//  
</script>

Answer 2

试试这个

<?php

include '../with_session.php';
include '../db-connection.php';
session_start();
$id=$_SESSION['id'];

$sid="SELECT s_id WHERE id=".$id." ";  //to get s_id coloumn value
$resultsid=mysqli_query($con, $sid);
while($rowid=mysqli_fetch_assoc($resultsid)) {
    $re_id = $rowid['s_id'];
}


$qamount= "SELECT price FROM services WHERE s_id=".$re_id." ";// selecting price to insert into    amount
$resultq= mysqli_query($con, $qamount);
while($row_data = mysqli_fetch_assoc($resultq)){
    $price = $row_data['price'];
}

?>
