Question

我使用Tag Manager plugin为我的表单创建标签，并使用jquery中的serialize（）函数将值传递给php。当我检索值时，我得到一个空字符串但没有serialize（）函数，标签创建者工作正常。

<input type="text" name="tags" placeholder="Tags" class="tm-input form-control tm-input-info" id="collaborationsSoughtInput" name="collaborationsSoughtInput" />

这是我的jquery函数

function adduser() {
    $.post("functions/add-user.php", $("#registerForm").serialize()).done(function(data) {
      var result = $.trim(data);
      if (result == "OK") {
        window.location.href = "login";
      } else {
        console.log("Register error :" + result);
      }
    });
  }

和php代码

  $collaborationsSoughtInput = $con->real_escape_string($_POST['hidden-tags']);

这是工作example

这里有完整的表格

<form action="" id="registerForm" class="mb-4" style="margin-bottom: 50px" method="post" enctype="multipart/form-data">
  <div class="form-group has-feedback row">
    <label for="fullnameInput" class="col-sm-3 col-form-label" required>Full Name *</label>
    <div class="col-sm-8">
      <input type="text" class="form-control" id="fullname" name="fullname" required>
    </div>
    <span id="fullNameError" class="color-red hide-me">Full Name Error</span>
  </div>
  <div class="form-group has-feedback row">
    <label for="usernameInput" class="col-sm-3 col-form-label">Username *</label>
    <div class="col-sm-8">
      <input minlength="4" type="text" class="form-control" id="username" name="username">
    </div>
    <span id="usernameError" class="color-red hide-me">Userame Error</span>
  </div>
  <div class="form-group has-feedback row">
    <label for="passwordInput" class="col-sm-3 col-form-label" required>Password *</label>
    <div class="col-sm-8">
      <input class="form-control" type="password" value="hunter2" id="password" name="password">
    </div>
    <span id="passwordError" class="color-red hide-me">Password Error</span>
  </div>
  <div class="form-group has-feedback row">
    <label class="col-sm-3 col-form-label" for="collaborationsSoughtInput">Collaborations Sought *</label><br/>
    <div class="col-sm-8">
      <input type="text" name="tags" placeholder="Tags" class="tm-input form-control tm-input-info" id="collaborationsSoughtInput" name="collaborationsSoughtInput" />
    </div>
    <span id="collaborationsError" class="color-red hide-me">Collaborations Error</span>
  </div>
</form>

在控制台中，我得到了这个

<b>Notice</b>:  Undefined index: hidden-tags in ...

Answer 1

.serialize（）的整个输出是空的？似乎你的表单选择器可能是错误的。

无法使用serialize（）函数通过jquery获取隐藏字段的值
