如何把两个不同的提交按钮在一个形式（与CI）？ [英] How to put 2 different Submit Buttons in a form (with CI)?

问题描述

我有一个表单，我想让用户选择两种不同的方式结帐：

I have a form where I want the user to choose 2 different way to checkout :

让我们说，用户输入他的地址，姓名和信用信息。
使用PayPal Pro，最后，我希望他能够选择是否要通过paypal或通过直接付款...结算，这将导致第二种形式。

Let say that the user enters his informations like his address, name and credit info. Using Paypal Pro, at the end, I want him to be able to choose whether or not he wants to checkout through paypal or through direct payment ... that would lead to a second form.

顺便说一句，使用CodeIgnieter，当跟着一个窗体与另一个，我得到第二个验证过程总是运行，我的意思是当我从第一个形式到第二个，在第二种形式，我会看到我的错误消息出现，对于每个字段，即使用户没有尝试提交。有没有办法避免这个错误？

By the way, with CodeIgnieter, when following a form with another one, I got the validation process of the second one that always run, I mean when I come from the first form to the second one, in the second form I will see my error messages appears, for each field even if the user didn't try to submit yet. Is there a way to avoid this bug ?

谢谢！

推荐答案

编辑：见结尾

它通常是：

查看：

<form method="post" action="mysite.com/submit">
    <input type="text" name="name1">
    <input type="text" name="name2">
    <input type="text" name="name3">

    <input type="submit" name="sbm" value="Direct">
    <input type="submit" name="sbm" value="PayPal">
</form>

在PHP（控制器可能）中：

In PHP (controller probably):

if($this->input->post('sbm') == "PayPal") { 
    // do something with PayPal
} else {
    // do something with direct payment
}

希望该按钮的标题（可见文本）与该值不同，请使用< button> 元素而不是< input type = submit> ：

Edited: If you would like the caption of the button (visible text) to differ from the value, use <button> element instead of the <input type="submit">:

<button name="payment_type" value="paypal" type="submit">I want to pay with PayPal</button>
<button name="payment_type" value="direct" type="submit">Or should I go with Direct Payment?</button>
