Question

我想将所有3个$_POST合并为1个变量但月份日不会出现，为什么会这样？

以下是代码：

<div id="register-birth-date">

  <input type="number" name="register-day" placeholder="DATE">

    <select id="register-month">
      <option value="00">Mouth</option>
      <option value="01">January</option>
      <option value="02">February</option>
      <option value="03">March</option>
      <option value="04">April</option>
      <option value="05">May</option>
      <option value="06">June</option>
      <option value="07">July</option>
      <option value="08">August</option>
      <option value="09">September</option>
      <option value="10">October</option>
      <option value="11">November</option>
      <option value="12">December</option>
    </select>

  <input type="number" name="   " placeholder="YEARS">

</div>

$air_user_registered_date = $_POST['register-day']."/".$_POST['register-month']."/".$_POST['register-years'];

Answer 1

您需要将name属性添加到select box个月和input box多年。

<div id="register-birth-date">

  <input type="number" name="register-day" placeholder="DATE" />

  <select name="register-month" id="register-month">
    <option value="00">Mouth</option>
    <option value="01">January</option>
    <option value="02">February</option>
    <option value="03">March</option>
    <option value="04">April</option>
    <option value="05">May</option>
    <option value="06">June</option>
    <option value="07">July</option>
    <option value="08">August</option>
    <option value="09">September</option>
    <option value="10">October</option>
    <option value="11">November</option>
    <option value="12">December</option>
  </select>

  <input type="number" name="register-years" placeholder="YEARS" />
</div>
