Question

我的表单似乎没有将值发送到表单操作页面。我试图将它们设置为变量，所有变量回显为未定义。我用了var_dump（$ _ POST）;并且它表示数组中的所有值都为null。我看过我的表格。我已经在线测试了代码以及wamp和xampp，但结果相同。如果有人能帮助我，我会非常感激。我已经为此工作了一个星期了。这是我的表单页面hash.php：

<html>
 <body>
 <h2>Modal Signup Form</h2>

 <button onclick="document.getElementById('id01').style.display='block'" 
style="width:auto;">Sign Up</button>

 <div id="id01" class="modal">
 <span onclick="document.getElementById('id01').style.display='none'" class="close" title="Close Modal">&times;</span>

 <form action="action.php" class="modal-content"  method= "post">
 <div class="container">
  <h1>Sign Up</h1>
  <p>Please fill in this form to create an account.</p>
  <hr>
  <label for="username"><b>Username</b></label>
  <input type="text" placeholder="Check Availability" name="username" required>

  <label for="email"><b>Email</b></label>
  <input type="text" placeholder="Enter Email" name="email" required>

  <label for="phone"><b>Phone</b></label>
  <input type="tel" minlength="10" maxlength="10" placeholder="Enter 10 digit Phone number" name="phone">

  <label for="psw"><b>Password</b></label> <span id = 'message'> </span>
  <input type="password" pattern= "^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[$@$!%*?&])(A-Za-z\d$@$!%*?&]{12,}" placeholder="Enter Password" id= "password" name="password"  onkeyup='check();' required>


  <label for="psw-repeat"><b>Repeat Password</b></label> 
  <input type="password" pattern= "^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[$@$!%*?&])(A-Za-z\d$@$!%*?&]{12,}" placeholder="Repeat Password"  id= "confirm-password" name="confirm-password" onkeyup='check();' required>

  <div class="clearfix">
    <button type="button" onclick="document.getElementById('id01').style.display='none'" class="cancelbtn">Cancel</button>
    <button type="submit" value="submit" class="signupbtn">Sign Up</button>
  </div>
  </div>
  </label>
  </form>


  <script>
  var check = function() {
  if (document.getElementById('password').value ==
      document.getElementById('confirm-password').value) {
      document.getElementById('message').style.color = 'green';
      document.getElementById('message').innerHTML = 'matching';
  } else {
      document.getElementById('message').style.color = 'red';
      document.getElementById('message').innerHTML = 'not matching';
  }
  }

  </script>




  <script>
  // Get the modal
  var modal = document.getElementById('id01');

  // When the user clicks anywhere outside of the modal, close it
  window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";
  }
  }
  </script>

  </body>
  </html>

我的表单操作是action.php：

  if (isset($_POST['username']))
  {
  echo "IT IS SET!";
  $username = $_POST['username'];
  $_POST['email'] = $email;
  $_POST['phone'] = $phone;
  $_POST['password'] = $password;
  $_POST['confirm-password'] = $confirmpassword;
  }
  var_dump($username);

  echo $password;
  echo $confirmpassword;
  echo $phone;
  echo $email;
  echo $username;
  var_dump($_POST);

Answer 1

你实际上在var_dump（）之前覆盖你的$ POST中的所有变量。尝试将其移至顶部。我也改变了你的任务，所以你不会覆盖他们。

while (scanf ("%d", (int)ph[i].vi.temperature) < 0) { 
warning: format '%d' expects argument of type 'int *', but argument 2 has type 'int'
