我想使用一个复选框来选择行表的项目,但是我有问题要获取用户在此处输入的每个项目的数量是我的html代码。我想用php有人可以帮帮我吗?
<form id="RegisterUserForm" action="register.php" method="post">
<table id="t01">

<th width="5%">Select</th>
<th width="20%">Picture</th>

答案 0 :(得分:0)
只是一个想法,但为什么你有一个复选框和数量相同的形式?我的意思是,如果所有金额都以0开头(或空白)并且用户更改为另一个数字,则表明他想要该产品。
然后,您只能在表单中使用此参数(每个参数都具有特定名称,可能包含产品的ID)。类似的东西:
<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>
此表单的输入将生成一个数组参数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
}
}
}
?>

和checkboxes
,形式:
<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
}
}
}
?>
