Question

我是新手编码并且需要选择两个选项的问卷...我可以选择选择并输出正确的答案，但是，选择的选项不会保留。如何在用户点击提交按钮后停留？我试图研究它并使用了几种不同的格式，但它仍然无法正常工作。不确定这是我的语法还是我没有正确的编码。我已经提供了代码的副本。

    <form method="post" action="">
        <p><span class="error">* required field.</span></p>
        <p>What is the pay period reported by Company X:</p>
        <input type="radio" name="payPeriod" value="1" <?php if (isset($_POST['payPeriod']) && $_POST['payPeriod']=='biWeekly') echo ' checked="checked"';?> />Bi-Weekly
        <input type="radio" name="payPeriod" value="2" <?php if (isset($_POST['payPeriod']) && $_POST['payPeriod']=='semiMonthly') echo ' checked="checked"';?> />Semi-Monthly
        <span class="error">* <?php echo $payPeriodErr;?></span>
        <br/>
        <p>What is the clients response to pay period:<br/>
        (How often do you get paid, once every two weeks or twice a month?)</p>
        <input type="radio" name="pay_Period" value="1" <?php if (isset($_POST['pay_Period']) && $_POST['pay_Period']=='bi_Weekly') echo ' checked="checked"';?> />Every two weeks
        <input type="radio" name="pay_Period" value="2" <?php if (isset($_POST['pay_Period']) && $_POST['pay_Period']=='semi_Monthly') echo ' checked="checked"';?> />Twice a month
        <span class="error">* <?php echo $pay_PeriodErr;?></span>
        <br/>
        <p>Does your pay day result on the same days of the week:<br/>
        (i.e.: Every pay checks are paid on Fridays.)</p>
        <input type="radio" name="payDay" value="1" <?php if (isset($_POST['payDay']) && $_POST['payDay']=='yes') echo ' checked="checked"';?> />Yes
        <input type="radio" name="payDay" value="2" <?php if (isset($_POST['payDay']) && $_POST['payDay']=='no') echo ' checked="checked"';?> />No
        <span class="error">* <?php echo $payDayErr;?></span>
        <br/>
        <br/>
        <button onclick="myFunction()">Submit</button>
        <br/>
        <br/>
    </form>

Answer 1

在您的PHP代码中，当您需要使用收音机$_POST['pay_Period']=='bi_Weekly'字段中指定的值时，您正在检查value。您将这些设置为1和2，因此您需要使用这些。那将是提交给你的。见下面的代码

<form method="post" action="">
   <p><span class="error">* required field.</span></p>
   <p>What is the pay period reported by Company X:</p>
   <input type="radio" name="payPeriod" value="1" <?php if (isset($_POST['payPeriod']) && $_POST['payPeriod']=='1') echo ' checked="checked"';?> />Bi-Weekly
   <input type="radio" name="payPeriod" value="2" <?php if (isset($_POST['payPeriod']) && $_POST['payPeriod']=='2') echo ' checked="checked"';?> />Semi-Monthly
   <span class="error">* <?php echo $payPeriodErr;?></span>
   <br/>
   <p>What is the clients response to pay period:<br/>
      (How often do you get paid, once every two weeks or twice a month?)
   </p>
   <input type="radio" name="pay_Period" value="1" <?php if (isset($_POST['pay_Period']) && $_POST['pay_Period']=='1') echo ' checked="checked"';?> />Every two weeks
   <input type="radio" name="pay_Period" value="2" <?php if (isset($_POST['pay_Period']) && $_POST['pay_Period']=='2') echo ' checked="checked"';?> />Twice a month
   <span class="error">* <?php echo $pay_PeriodErr;?></span>
   <br/>
   <p>Does your pay day result on the same days of the week:<br/>
      (i.e.: Every pay checks are paid on Fridays.)
   </p>
   <input type="radio" name="payDay" value="1" <?php if (isset($_POST['payDay']) && $_POST['payDay']=='1') echo ' checked="checked"';?> />Yes
   <input type="radio" name="payDay" value="2" <?php if (isset($_POST['payDay']) && $_POST['payDay']=='2') echo ' checked="checked"';?> />No
   <span class="error">* <?php echo $payDayErr;?></span>
   <br/>
   <br/>
   <button onclick="myFunction()">Submit</button>
   <br/>
   <br/>
</form>

您需要了解的有关单选按钮的所有内容均为here。也许你会找到一些其他有用的信息

如果向下滚动一下，您将看到如何检查某些单选按钮。

错过了javascript，我会为你找一个解决方案一段时间以前就已经提出了一个相关的问题，可以找到here

如何在提交按钮后保持我的单选按钮保持选中状态？
