Question

我需要传递两个参数名称为＆＃34; supplier＆＃34;和＆＃34;股票名称＆＃34;在下面的sql语句中。

<?php
include_once("init.php");

$line = $db->queryUniqueObject("SELECT * FROM stock_details  WHERE stock_name ='" . $_POST['stock_name'] . "'");
$cost = $line->company_price;
$sell = $line->selling_price;
$stock_id = $line->stock_id;
$line = $db->queryUniqueObject("***SELECT * FROM customer_stock  WHERE name ='" . $_POST['stock_name'] . "'"***);
$stock = $line->quantity;

if ($line != NULL) {

    $arr = array("cost" => "$cost", "sell" => "$sell", "stock" => "$stock", "guid" => $stock_id);
    echo json_encode($arr);

} else {
    $arr1 = array("no" => "no");
    echo json_encode($arr1);

}
?>

谢谢

我认为通过＆＃34;参数＆＃34;你的意思是＆＃34;条件＆＃34;。

"SELECT * FROM customer_stock  WHERE name ='" . $_POST['stock_name'] . "' AND supplier = '" . $_POST['supplier'] . "'"

如何通过sql select语句传递参数？
