从产品表中循环产品,将它们添加到购物车表中。只应选中复选框选中的产品,但如果选择,则选中的产品不对应.. 这是获取产品的HTML
<html>
<form action="#" id="" class="horizontal-form" method="post">
<?php
$LISTP = "SELECT * FROM products ORDER BY id";
$sn = 0;
$stmt = $pdo->prepare($LISTP);
$stmt->execute();
while($list = $stmt->fetch(PDO::FETCH_ASSOC)){
$sn = $sn + 1;
$ID = $list['id'];
$NAME = $list['name'];
?>
<input type="checkbox" name="slected[]" class="checkboxes" value="1" />
<input type="hidden" name="productid[]" class="" value="<?php echo $ID;?>" />
<input type="text" name="name[]" class="" value="<?php echo $NAME;?>" />
<?php }?> </form>
<?php
// now when we submot the form
$slected = $_POST['slected'];
$prod = $_POST['productid'];
$name = $_POST['name'];
foreach($prod as $key => $product){
if($slected[$key]>0){
echo $product.' '.$name[$key].' '.@$slected[@$key].'--<br>';
}
// the problem is here, if you check all product it will work well, but if you check the second one
// it would echo the second one giving it the name of the first one which was not checked at all
?>
答案 0 :(得分:0)
我过去常常以同样的方式做到这一点,并且发现了我认为更好的方法。不要使用存储ID的隐藏输入,只需使用ID作为所有表单变量键的索引:
<input type="checkbox" name="slected[<?php echo $ID; ?>]" class="checkboxes" value="1" />
<input type="text" name="name[<?php echo $ID; ?>]" class="" value="<?php echo $NAME;?>" />
然后,您的PHP可以简化:
// now when we submot the form
$slected = $_POST['slected'];
$name = $_POST['name'];
foreach( (array)$slected as $ID => $on ) {
echo $product . ' ' . $name[$ID] . ' ' . $ID . '--<br>';
}
所以 - 基本上,你的$slected
变量将包含一系列仅被选中的项目,并且你已经在$ slected数组中内置了产品ID。
