Question

我不能为我的生活弄清楚这一点。

我有以下表单，提交时返回一个空数组？它在提交时会转到正确的页面（index.php）但它没有传递任何内容作为GET或POST。两者都不使用var_dump（$ _ POST）返回任何内容。有什么想法吗？

    <form action="index.php" method="post">
    <div class="form-group">
        <label for="orderName">What is your name?</label>
        <input type="textbox" class="form-control" id="orderName" aria-describedby="orderName" placeholder="Enter name">
    </div>
    <div class="form-group">
        <label for="orderEmail">What is your email address?</label>
        <input type="textbox" class="form-control" id="orderEmail" aria-describedby="orderEmail" placeholder="Enter email">
    </div>
    <div class="form-group">
        <label for="orderCopies">How many copies of the book would you like?</label>
        <input type="textbox" class="form-control" id="orderCopies" aria-describedby="orderCopies" placeholder="Enter amount of books">
        <small id="oderCopiesHelp" class="form-text text-muted">Note: each book is $35 (including postage)</small>
    </div>
    <div class="form-group">
        <label for="orderAddress">Where would you like the book/s sent to?</label>
        <textarea class="form-control" id="orderAddress" rows="3"></textarea>
    </div>
    <div class="form-group">
        <label for="orderComments">Order comments</label>
        <textarea class="form-control" id="orderComments" rows="3"></textarea>
    </div>             
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
    <button type="submit" class="btn btn-primary">Send order</button>
    </form>

Answer 1

输入需要name属性，标记中缺少该属性。

例如，

<input type="textbox" class="form-control" name="orderName" id="orderName" aria-describedby="orderName" placeholder="Enter name">

name，<input>和<textarea>上包含<button>个属性的代码：

<form action="index.php" method="post">
    <div class="form-group">
        <label for="orderName">What is your name?</label>
        <input type="textbox" class="form-control" name="orderName" id="orderName" aria-describedby="orderName" placeholder="Enter name">
    </div>
    <div class="form-group">
        <label for="orderEmail">What is your email address?</label>
        <input type="textbox" class="form-control" name="orderEmail" id="orderEmail" aria-describedby="orderEmail" placeholder="Enter email">
    </div>
    <div class="form-group">
        <label for="orderCopies">How many copies of the book would you like?</label>
        <input type="textbox" class="form-control" name="orderCopies" id="orderCopies" aria-describedby="orderCopies" placeholder="Enter amount of books">
        <small id="oderCopiesHelp" class="form-text text-muted">Note: each book is $35 (including postage)</small>
    </div>
    <div class="form-group">
        <label for="orderAddress">Where would you like the book/s sent to?</label>
        <textarea class="form-control" name="orderAddress" id="orderAddress" rows="3"></textarea>
    </div>
    <div class="form-group">
        <label for="orderComments">Order comments</label>
        <textarea class="form-control" name="orderComments" id="orderComments" rows="3"></textarea>
    </div>             
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
    <button type="submit" class="btn btn-primary" name="submitButton">Send order</button>
</form>

Answer 2

您需要为每个输入元素添加名称属性标记。 name属性和值通过post方法发送到脚本以接收它。

Answer 3

对于每个输入标记，始终使用name属性来传递表单数据。

实施例

<input type="textbox" class="form-control" id="orderName" name="orderName" aria-describedby="orderName" placeholder="Enter name">

表格不发送数据？
