标签: php checkbox

我正在尝试检查是否已在PHP中选中了复选框以便注册。但它现在不能正常工作。这是我目前使用的代码,用于检查是否已经检查过。

if(!isset($_POST['tos']))
  $this->errors[] = 'Please accept our Terms of Service.';

这是HTML代码。

<div class="checkbox">
<label>
<input type="checkbox" name="tos" value="0"> I agree to the <a href="#">Terms of Service</a> and <a href="#">Privacy Policy</a>
</label>
</div>

完整表单代码:

        <form role="form" method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>">
              <div class="form-group">

              <div class="row">
                  <div class="col-sm-6">
                  <label for="firstname">Firstname</label>
                  <input type="text" class="form-control" id="firstname" name="firstname" placeholder="Firstname">
                  </div>
                  <div class="col-sm-6">
                  <label for="surname">Surname</label>
                  <input type="text" class="form-control" id="surname" name="surname" placeholder="Surname">
                  </div>
              </div>
              </div>
              <div class="form-group">
                <label for="username">Username</label>
                <input type="text" class="form-control" id="ruser" name="ruser" placeholder="Username">
              </div>
              <div class="form-group">
                <label for="email2">Email address</label>
                <input type="email" class="form-control" id="remail" name="remail" placeholder="Enter email">
              </div>
              <div class="form-group">
                <div class="row">
                  <div class="col-sm-6">
                  <label for="password2">Password</label>
                  <input type="password" class="form-control" id="rpass" name="rpass" placeholder="Password">
                  </div>
                  <div class="col-sm-6">
                  <label for="password2">Repeat password</label>
                  <input type="password" class="form-control" id="rpass2" name="rpass2" placeholder="Password">
                  </div>
                </div>
              </div>
              <div class="checkbox">
                <label>
                  <input type="checkbox" name="tos" value="0"> I agree to the <a href="#">Terms of Service</a> and <a href="#">Privacy Policy</a>
                </label>
              </div>
               <input type="hidden" name="secur" value="<?php echo $ip;?>"/>
               <input type="hidden" name="token" value="<?php echo $token;?>"/>
              <button type="submit" name="register" class="btn btn-block btn-color btn-xxl">Create an account</button>
            </form>

这段代码有什么问题?任何帮助将不胜感激。

if(!isset($_POST['tos']))
  $this->errors[] = 'Please accept our Terms of Service.';`

这样做是说如果$ _POST中没有'tos',则抛出错误。

实际上你应该在之前用javascript,检查这个客户端。将表单发送到服务器。

你也可以......

<input type="checkbox" name="tos" value="accepted" checked>

和PHP:

if(isset($_POST['tos']) && $_POST['tos']==='accepted') echo 'All good'; 
else array_push($errors,'err code here'); //to add to $error array

我不确定你是否使用jQuery,但只是为了更友好的用户方法:

var tos = $('#tos');
var notice = $('.notice');
tos.on('click',function(){
  if(tos.is(':checked')){
    notice.text('Thank you.');
  }
  else{
   notice.text('Please accept our ToS to continue.');
  }
})

See a working example here.如果未经检查,您甚至可以将表单全部停止。顺便说一句,如果我没记错checkbox输入只发送POST数据,如果选中。
