Question

我正在研究多维数组，但我遇到了问题

想象一下，我有一家公司可以订购一些家具 FX 5椅子的不同类型的宽度不同标准价格不同的折扣（％）和折扣后的价格现在是什么

如果公司可以选择5把椅子中的3把到他们的设计范围，并通过复选框添加每把椅子。然后我需要设置该单位的折扣和“最终价格”并且我要反复进行，所以我可以在以后添加更多的椅子。

我的想法是这样的

请注意，如果没有折扣，它必须能够在折扣中添加一个空字段，并且我必须能够读取给定单位的给定输入的值

我希望你能帮助我并感谢你的努力的Mikkel

<?php

$furniture_id = $_POST['furniture_id'];
$discount = $_POST['discount'];
$netto_price = $_POST['netto_price'];

if (isset($furniture_id)){


$get_info = array($furniture_id, $discount, $netto_price); 

$counter = 0;
$counter2 = 0;
foreach($get_info as $shop){
    echo "id: " . $shop[$counter][$counter02]." costs ".$shop[0][1]." and you get ".$shop[0][2]."<br />";
$counter++;
    if ($counter2 > 3){
        $counter2 = 0;
    }
}

//OR

$shop2 = array($furniture_id, $discount, $netto_price); 

foreach ($row as $rows){
    echo "<li><b>The row number $rows</b>";
    echo "<ul>";

    for ($col = 0; $col < 3; $col++){

    }

    echo "</ul>";

Answer 1

嗯，我找到了一个答案，它并不像我想要的那样完美，但我的工作让我很开心

我必须在包含model_id的表单中添加一个隐藏字段，以便我可以将它与复选框发送的model_id匹配

<?php
mysql_connect('localhost', 'root', '') or 
die("Could not connect: " . mysql_error());
mysql_select_db("hassberg");

$customer_id = 4;
?>

<?php
$sql = 'INSERT INTO tabelname (customer_id, model_id, discount, netto) VALUES ';

if(isset($_POST['chosen_model_id']) && count($_POST['chosen_model_id']) > 0){
$count = count($_POST['chosen_model_id']);
$i = 1;
foreach($_POST['chosen_model_id'] as $value){
    $key = array_search($value, $_POST['hidden_furniture_id']);

    $sql .= '(' . $customer_id . ',' . 
              $_POST['hidden_furniture_id'][$key] ."," . 
              $_POST['netto_price'][$key] ."," . 
              $_POST['discount'][$key] . ")"; 
    $sql .= ($i<$count) ? ", " : "";
    $i++;
}
    echo '<p>' . $sql . '</p>';     
}
?>

<form name="create01" method="post" action="<?php echo $PHP_SELF; ?> ">
<?php 
$result = mysql_query("SELECT id
           FROM furniture_model;");
if (mysql_num_rows($result) == 0){ // Exits if your db table is empty

  exit;

while($row_model = mysql_fetch_assoc($result)){
