我有幾個單選按鈕,A和B.兩個都有四個單選按鈕。 我的代碼現在回顯所選單選按鈕的值,但這不是我想要的。我想要檢查哪個按鈕被選中,然後回顯產品的名稱和價格。PHP檢查單選按鈕,然後輸出名稱和價格

當然我GOOGLE了當我得到這個問題,我發現這一點。但是,當我像上面實現它時,這給我一個錯誤
錯誤: (!)解析錯誤:語法錯誤,意外'}',期待','或';'在C:\ WAMP \ WWW \上線OK \ form.php的78
<?php
$radio = $_POST['RadioName'];
if ($radio == 'Value') {
echo "Print The Price Here"}
?>
後來我發現:但是這給我的錯誤:(!) 解析錯誤:語法錯誤,意外 '}',期待',' 要麼 ';'在C:\ WAMP \ WWW \ OK \ form.php的上線81
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST')
{
if ($_POST['RadioName'] == "Value")
{
echo ""
}
else if ($_POST['RadioName'] == "Value2")
{
echo ""
}
}
?>
時等來實現:
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST')
{
if ($_POST['A'] == "A1")
{
echo $A1
}
else if ($_POST['A'] == "A2")
{
echo $A2
}
}
?>
是否有另一種解決方案?或者這些解決方案中的任何一種都可以調整,以便它們能夠工作?
你在echo $ A1後缺少分號,它應該是echo $ A1;在線78 – 2014-10-20 09:44:25
