Php / mysqli销售系统

标签： php mysqli

所以，我正在做一个php / mysqli的项目，我正在尝试做一个销售系统，我有3个表涉及卖点。一个是我要传递产品的地方，另一个是我想通过卖家ID的地方 对于我需要传递fk（product_id）的产品，所以我可以得到价格和我的jquery过程它做数学。目前系统正在运行，但我不知道如何使用这个，所以我可以选择我的数据库产品和卖家而不是表格上的选项。我从未做过销售系统，所以我在这方面有点亏。

这是我的代码：

    <script type="text/javascript">
        jQuery(document).ready(function($){

           var codigoDeBarras = $('input[name="codigoDeBarras"]');
           var nif = $('input[name="NIF"]');
           var valorUnidade = $('input[name="valorUnidade"]');
           var valorTotal = $('input[name="valorTotal"]');
           var quantidade = $('input[name="Quantidade"]');

           $('select#produtos').change(function(){
              if( !$(this).find('option:selected').val() == '' ){
                  var price = parseInt($(this).find('option:selected').attr('data-price'));
                  var code = $(this).find('option:selected').attr('data-code');
                  $('#price').html(price);
                  $('#total_price').html(price * parseInt(quantidade.val()));
                  codigoDeBarras.val(code);
                  valorUnidade.val(price);
                  valorTotal.val(price * parseInt(quantidade.val()));
              }
           });
           quantidade.bind('click keyup', function(){
              if( !$('select#produtos').find('option:selected').val() == '' ){
                  var price =  $('select#produtos').find('option:selected').attr('data-price');
                  $('#total_price').html(price * parseInt($(this).val()));
                  valorTotal.val(price * parseInt(quantidade.val()));
              }
           });
           $('select#fornecedor').change(function(){
              if( !$(this).find('option:selected').val() == '' ){
                nif.val($(this).find('option:selected').attr('data-nif'));
              }
           });
        });
    </script>

我知道这是一个很大的问题，但是如果你能给我一个如何理解它的想法，那将非常有帮助。

编辑：所以，现在我可以将jquery中的数据导入到数组中，但仍然不知道如何将所选选项应用到我的数据库中......这是我的代码：

    <?php


$mysqli = new mysqli("xxxxx", "xxxxx", "xxxx", "xxxx", xxxx);
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}


   if( $_POST != '' && $_POST != NULL ){

                $query = "SELECT * FROM produto";
                $from = 0;
                $to = 30;
                $query .= " LIMIT ".$from.",".$to;

            $result = mysqli_query($link, $query) or die("SQL Error 1: " . $mysqli->error);
            while ($row = $result->fetch_assoc()) { 
                $produtos[] = array(
                    'Preco' => $row['Preco'],
                    'Nome' => $row['nome']

                 );
            }
            echo json_encode($produtos);

                $query2 = "SELECT * FROM fornecedor";
                $from = 0;
                $to = 30;
                $query .= " LIMIT ".$from.",".$to;

            $result = mysqli_query($link, $query2) or die("SQL Error 1: " . $mysqli->error);
            while ($row = $result->fetch_assoc()) { 
                $fornecedor[] = array(
                    'NIF' => $row['NIF'],
                    'Nome' => $row['Nome']

                 );
            }
            echo json_encode($fornecedor);

            print_r($fornecedor);


            $encomenda_data = $_POST['DataDeEncomenda'];
            $encomenda_qty = $_POST['Quantidade'];
            $encomenda_nif = $fornecedor[0]; // Forget this line and the other bellow ( testing purpose)
            $encomenda_codigo = $_POST['Produto'];
            $encomenda_preco = $produtos[0];
            $encomenda_total = $_POST['valor'];


            $sql3 = "INSERT INTO encomendain ( DataDeEncomenda, Quantidade, NIF, codigoDeBarras, Preço, ValorTotal) VALUES ( '$encomenda_data' , '$encomenda_qty' , '$encomenda_nif' , '$encomenda_codigo' , '$encomenda_preco', '$encomenda_total') ";


            $result = mysqli_query($link, $sql3) or die("Could not insert".mysqli_error($link));
            header('Location: paginaEncomendaIn.php');

        }


    ?>

连接到您的数据库使用（从http://www.php.net/manual/en/mysqli.quickstart.connections.php复制）

<?php
$mysqli = new mysqli("localhost", "user", "password", "database");
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
echo $mysqli->host_info . "\n";

$mysqli = new mysqli("127.0.0.1", "user", "password", "database", 3306);
if ($mysqli->connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}

echo $mysqli->host_info . "\n";
?>

从表中读取并存储在主要从http://www.jqwidgets.com/jquery-widgets-documentation/documentation/phpintegration/bind-jquery-grid-to-mysql-database-using-php.htm复制的jquery数组中，以适应使用的mysqli 

// get data and store in a json array
$query = "SELECT * FROM customers";
$from = 0;
$to = 30;
$query .= " LIMIT ".$from.",".$to;

$result = mysqli_query($query) or die("SQL Error 1: " . $mysqli->error);
while ($row = $res->fetch_assoc()) {
    $customers[] = array(
        'CompanyName' => $row['CompanyName'],
        'ContactName' => $row['ContactName'],
        'ContactTitle' => $row['ContactTitle'],
        'Address' => $row['Address'],
        'City' => $row['City']
     );
}
echo json_encode($customers);

您需要修改此项以从数据库中读取并填充html表单中的字段。
