NULL单选按钮值

在我的代码的第13行，我得到一个NULL $ NaN值。如果我用静态整数替换$ _POST ['amount']，则代码POST为正确的值。但试图添加一点功能，现在我无法获取数据通过？NULL单选按钮值

'NAN'应该表示不是数字 - 我猜？ – codingbiz

不要amount field为array 用户select只有一个这些。

试试这个，

<p> 
    <label>Select your package</label> 
    <input type = "radio" 
     name = "amount" 
     id = "sizeSmall" 
     value = "50" 
     checked = "checked" /> 
    <label for = "sizeSmall">$50.00</label> 

    <input type = "radio" 
     name = "amount" 
     id = "sizeMed" 
     value = "75" /> 
    <label for = "sizeMed">$75.00</label> 

    <input type = "radio" 
     name = "amount" 
     id = "sizeLarge" 
     value = "large" /> 
    <label for = "sizeLarge">$100.00</label> 
</p>

，或者如果您确实将它命名为amount [size]，然后将其作为'$ _POST [“amount”] [“size”];' – Orangepill

同样问题与表单中的金额或金额[]相关联。 – brad

@Orangepill我真的被困在这里。 – brad

您NAN问题是从value="large"到来。它应该是value="100"或任何您需要的值。我只能假设，值是如何处理的，你的处理程序是期待一个数字而不是一个字符串。
