checkbox to select item of a row table and get the amount that the user input in the from

我想使用一个复选框来选择一个行表的项目，但我有问题，以获得每个项目的数量，用户输入从这里是我的html代码。我想用php有人可以帮助我吗?

<form id="RegisterUserForm" action="register.php" method="post">
                    <table id="t01">
                        <tr>
                            <th width="5%">Select</th>
                            <th width="20%">Picture</th>
                            <th width="55%">Description</th>
                            <th width="10%">Amount</th>
                            <th width="10%">Price</th>
                        </tr>
                        <tr> 
                            <td><input id="pedido1" name="check_list[]" type="checkbox" value="1"/>Product 1</td>
                            <td id="imagem1"><img src="imagen1.png"></td>
                            <td>Descriptiondo Product 1</td>
                            <td><input id="qt" name="qt" type="text" class="text" value="1" /></td>
                            <td>13.50</td>
                        </tr>
                        <tr> 
                            <td><input id="pedido1" name="check_list[]" type="checkbox" value="1"/>Product 2</td>
                            <td id="imagem1"><img src="imagen2.png"></td>
                            <td>Descriptiondo Product 2</td>
                            <td><input id="qt" name="qt" type="text" class="text" value="1" /></td>
                            <td>13.50</td>
                        </tr>
                        <tr> 
                            <td><input id="pedido1" name="check_list[]" type="checkbox" value="1"/>Product 3</td>
                            <td id="imagem1"><img src="imagen3.png"></td>
                            <td>Descriptiondo Product 3</td>
                            <td><input id="qt" name="qt" type="text" class="text" value="1" /></td>
                            <td>13.50</td>
                        </tr>
                        <tr> 
                            <td><input id="pedido1" name="check_list[]" type="checkbox" value="1"/>Product 4</td>
                            <td id="imagem1"><img src="imagen4.png"></td>
                            <td>Descriptiondo Product 4</td>
                            <td><input id="qt" name="qt" type="text" class="text" value="1" /></td>
                            <td>13.50</td>
                        </tr>
                    </table>
                        <button id="register" type="submit">register</button>
                </form>

只是一个想法，但是为什么在相同的形式中有一个复选框和金额呢?我的意思是，如果所有的金额都以0(或空白)开头，而用户更改为另一个数字，很明显他想要那个产品。

那么您只能在表单中使用这个参数(每个参数都有特定的名称，可能包含产品的id)。比如:

<form>
    //rest of html
    <input name="qt[idproduct]" type="text" class="text" value="" />
    //rest of html
    <input name="qt[idproduct]" type="text" class="text" value="" />
    //rest of html
    <input name="qt[idproduct]" type="text" class="text" value="" />
    //rest of html
</form>

这个表单的输入将产生一个数组参数qt，您可以通过以下方式获取值:

<?php
    if(isset($_GET['qt'])) { //or $_POST
        foreach ($_GET['qt'] as $id => $total) {
            if(!empty($total) && $total > 0 && is_numeric($total)) { // just checking if you are receiving a number bigger than 0
                echo "Product: " . $id . " total: " . $total . "<br />"; // do your thing
            }
        }
    }
?>

与checkboxes，形成:

<form>
    //rest of html
    <input name="check_list[idproduct1]" type="checkbox" value="1"/>Product 1
    <input name="qt[idproduct1]" type="text" class="text" value="" />
    //rest of html
    <input name="check_list[idproduct2]" type="checkbox" value="1"/>Product 2
    <input name="qt[idproduct2]" type="text" class="text" value="" />
    //rest of html
    <input name="check_list[idproduct3]" type="checkbox" value="1"/>Product 3
    <input name="qt[idproduct3]" type="text" class="text" value="" />
    //rest of html
    <input type="submit">
</form>

php:

<?php
    if(isset($_GET['check_list'])) { //or $_POST
        foreach ($_GET['check_list'] as $id => $value) {
            $total = $_GET['qt'][$id];
            if(!empty($total) && $total > 0 && is_numeric($total)) { // just checking if you are receiving a number bigger than 0
                echo "Product: " . $id . " total: " . $total . "<br />"; // do your thing
            }
        }
    }
?>
