我有一个用户创建自定义问题的表单。为此,用户需要介绍问题(例如:您的手机是什么?)以及字段的类型(文本、长文本、复选框、选择菜单、单选按钮)。如果用户选择一个复选框字段,选择菜单或单选按钮,他还需要介绍问题的可用选项。

在数据库中,问题被插入到问题和question_options表中,如下所示:

问题表:

代码语言:javascript
复制
id       question         type        conference_id
1          Text            text             1 
2        Checkbox         checkbox          1 
3          Radio           radio_btn        1 
4          select         select_menu       1 
5         textarea         long_text        1 
6           file             file           1 

Registration_type_questions数据透视表:

代码语言:javascript
复制
id registration_type_id   question_id  required
1         1                     1          1   
2         1                     2          1   
3         1                     3          0   
4         1                     4          0   
5         1                     5          0   
6         1                     6          1   

这些选项存储在questions_options表中:

代码语言:javascript
复制
   id   question_id   value

    1          2        check1  
    2          2        check2  
    3          3        rad1    
    4          3        rad2    
    5          4        select1
    6          4        select2 

然后在视图中,我想要正确地显示在视图registration.blade.php的输入(文本,单选按钮,复选框,选择,文本区和输入文件)基于类型存储在列“类型”的问题表。并且如果数据透视表中所需的列是"1“,则也添加所需的属性。

当问题的类型为文本、单选按钮、选择、文本区或文件时,会将所需属性添加到表单域中。

但是复选框不能正常工作,因为在复选框的情况下,如果问题是checkbox类型,并且问题是必需的,这应该意味着用户需要回答该问题,但不应该意味着用户需要选中所有复选框。

问题是,使用函数getHTMLInput(),为复选框生成的html在每个复选框输入中都是必需的,因此用户需要选中所有复选框:

代码语言:javascript
复制
 <div class="form-group">
    <label for="participant_question">Checkbox</label>
    <div class="form-check">
      <input type="checkbox" name="participant_question[]" value="check1" class="form-check-input" required="">  
      <label class="form-check-label" for="exampleCheck1">check1</label>
    </div> 
    <div class="form-check">
      <input type="checkbox" name="participant_question[]" value="check2" class="form-check-input" required="">    
      <label class="form-check-label" for="exampleCheck1">check2</label>
    </div>

    <input type="hidden" name="participant_question_required[]" value="1">
    <input type="hidden" value="2" name="participant_question_id[]">
  </div>

你知道如何解决这个问题吗?当需要自定义问题时,这应该意味着该问题是必需的,因此用户应该至少选择一个复选框,但不应该意味着用户需要选中所有复选框。

另外,如果需要自定义问题,您知道如何在每个问题中添加此"<span class="text-primary">*</span>“标签吗?

问题模型中的GetHtmlInput():

代码语言:javascript
复制
class Question extends Model
{
    protected $fillable = [
        'question', 'type', 'conference_id',
    ];

    public static $typeHasOptions = [
        'radio_btn',
        'select_menu',
        'checkbox'
    ];

    public function registration_type()
    {
        return $this->belongsToMany('App\RegistrationType', 'registration_type_questions')
            ->withPivot('required');
    }

    public function options()
    {
        return $this->hasMany('App\QuestionOption');
    }

    public function hasOptions()
    {
        return in_array($this->type, self::$typeHasOptions);
    }

    public function getHtmlInput($name = "", $options = "", $required = false, $class = "", $customtype = false) {

        $html = '';
        $html .= $customtype == 'select_menu' ? "<select name='participant_question' class='form-control' " . ($required ? " required" : "")
            . ">" : '';

        if (empty($options)) {
            switch ($customtype) {
                case "text":
                    $html .= " 
                    <input type='text' name='participant_question' class='form-control'" . ($required ? " required" : "")
                        . ">";
                    break;

                case "file":

                    $html .= " 
                    <input type='file' name='participant_question' class='form-control'" . ($required ? " required" : "") . ">";
                    break;

                case "long_text":
                    $html .= "
                <textarea name='participant_question' class='form-control' rows='3'" . ($required ? " required" : "") . ">"
                        . $name .
                        "</textarea>";

                    break;
            }
        } else {
            foreach ($options as $option) {
                switch ($customtype) {
                    case "checkbox":
                        $html .= " 
                <div class='form-check'>
                    <input type='checkbox' name='participant_question[]' value='" . $option->value . "' class='form-check-input'" . ($required ? " required" : "") . ">" .
                            '    <label class="form-check-label" for="exampleCheck1">' . $option->value . '</label>' .
                            "</div>";
                        break;
                    case "radio_btn":
                        $html .= " 
                <div class='form-check'>
                    <input type='radio' name='participant_question[]' value='" . $option->value . "' class='form-check-input'" . ($required ? " required" : "") . ">" .
                            '    <label class="form-check-label" for="exampleCheck1">' . $option->value . '</label>' .
                            "</div>";
                        break;
                    case "select_menu":
                        $html .= "<option value='" . $option->value . "'>" . $option->value . "</option>";
                        break;
                }
            }
        }
        $html .= $customtype == 'select_menu' ? "</select>" : '';

        return $html;
    }
}

然后getHtmlInput()的用法如下:

代码语言:javascript
复制
@if ($allParticipants == 0)
    @foreach($selectedRtype['questions'] as $customQuestion)
        <div class="form-group">
            <label for="participant_question">{{$customQuestion->question}}</label>
            @if($customQuestion->hasOptions() && in_array($customQuestion->type, ['checkbox', 'radio_btn', 'select_menu']))
                {!! $customQuestion->getHtmlInput(
                    $customQuestion->name,
                    $customQuestion->options,
                    ($customQuestion->pivot->required == '1'),
                    'form-control',
                    $customQuestion->type)
                !!}

            @else
                {!! $customQuestion->getHtmlInput(
                    $customQuestion->name,
                    [],
                    ($customQuestion->pivot->required == '1'),
                    'form-control',
                    $customQuestion->type)
                !!}
            @endif
            <input type="hidden"
                   name="participant_question_required[]"
                   value="{{ $customQuestion->pivot->required }}">
            <input type="hidden"
                   value="{{ $customQuestion->id }}"
                   name="participant_question_id[]"/>
        </div>
    @endforeach
@endif

使用getHTMLInput()生成的超文本标记语言:

代码语言:javascript
复制
<form method="post" action="">


  <div class="form-group">
    <label for="participant_question">Text</label>
    <input type="text" name="participant_question" class="form-control" required="">
    <input type="hidden" name="participant_question_required[]" value="1">
    <input type="hidden" value="1" name="participant_question_id[]">
  </div>

  <div class="form-group">
    <label for="participant_question">Checkbox</label>
    <div class="form-check">
      <input type="checkbox" name="participant_question[]" value="check1" class="form-check-input" required="">  
      <label class="form-check-label" for="exampleCheck1">check1</label>
    </div> 
    <div class="form-check">
      <input type="checkbox" name="participant_question[]" value="check2" class="form-check-input" required="">    
      <label class="form-check-label" for="exampleCheck1">check2</label>
    </div>

    <input type="hidden" name="participant_question_required[]" value="1">
    <input type="hidden" value="2" name="participant_question_id[]">
  </div>

  <div class="form-group">
    <label for="participant_question">Radio</label>
    <div class="form-check">
      <input type="radio" name="participant_question[]" value="rad1" class="form-check-input">  
      <label class="form-check-label" for="exampleCheck1">rad1</label>
    </div> 
    <div class="form-check">
      <input type="radio" name="participant_question[]" value="rad2" class="form-check-input">   
      <label class="form-check-label" for="exampleCheck1">rad2</label>
    </div>
    <input type="hidden" name="participant_question_required[]" value="0">
    <input type="hidden" value="3" name="participant_question_id[]">
  </div>

  <div class="form-group">
    <label for="participant_question">select</label>
    <select name="participant_question" class="form-control">
      <option value="select1">select1</option>
      <option value="select2">select2</option>
    </select>

    <input type="hidden" name="participant_question_required[]" value="0">
    <input type="hidden" value="4" name="participant_question_id[]">
  </div>

  <div class="form-group">
    <label for="participant_question">textarea</label>
    <textarea name="participant_question" class="form-control" rows="3"></textarea>
    <input type="hidden" name="participant_question_required[]" value="0">
    <input type="hidden" value="5" name="participant_question_id[]">
  </div>

  <div class="form-group">
    <label for="participant_question">file</label>
    <input type="file" name="participant_question" class="form-control" required="">
    <input type="hidden" name="participant_question_required[]" value="1">
    <input type="hidden" value="6" name="participant_question_id[]">
  </div>

  <input type="submit" class="btn btn-primary" value="Store">
</form>

此外,在w3c验证器之类的超文本标记语言验证器中检查此表单时,会出现一些错误:

label元素的

  • 属性必须引用非隐藏窗体控件。在"Text
  • “中,label元素的for属性必须引用非隐藏表单控件。在”Checkb“

这是因为您的foreach循环中包含复选框组html:

代码语言:javascript
复制
 foreach ($options as $option) {
                switch ($customtype) {
                    case "checkbox":
                        $html .= " 
                <div class='checkbox-group' " . ($required ? " required" : "") . ">

你需要考虑如何解决这个问题,比如使用像$checkboxesFound这样的变量,并在函数开始时将其设置为0,当case为复选框时,递增该变量,如果为$checkboxesFound == 0,则回显group div。

将您的getHtmlInput()替换为以下内容

代码语言:javascript
复制
public function getHtmlInput($question_id, $index_position, $name = "", $options = "", $required = false, $class = "", $customtype = false) {

    //dd($name);
    $html = '';
    $html .= $customtype == 'select_menu' ? "<select name='participant_question[".$question_id."][".$index_position."]' class='form-control' " . ($required ? " required" : "")
        . ">" : '';

    if (empty($options)) {
        switch ($customtype) {
            case "text":

                $html .= " 


                <input type='text' name='participant_question[".$question_id."][".$index_position."]' class='form-control'" . ($required ? " required" : "")
                    . ">";


                break;

            case "file":

                $html .= " 


                <input type='file' name='participant_question[".$question_id."][".$index_position."]' class='form-control'" . ($required ? " required" : "") . ">";

                    . $name .
                    "</textarea>";

                break;
        }
    } else {

您需要将名称属性设置为与相同组选项相同,才能正确使用所需选项。

但是在您的代码中,包括不同选项组的所有选项都共享相同的名称属性。

上面的代码没有经过测试。但我希望它能为你工作

HTML5没有实现需要一组复选框的解决方案,所以您可以通过一些更改来实现它。首先,在您的控制器上,您需要更改它,以实现与您对选择菜单所做的相同操作。

代码语言:javascript
复制
// on top of your method:
$html .= $customtype == 'checkbox' ? "<div class='checkbox-group ".($required ? " required" : "")."'>" : '';
// at the bottom
$html .= $customtype == 'checkbox' ? "</div>" : '';

然后,在您的“复选框”中,您只需打印位于“所需的复选框组”中的选项:

代码语言:javascript
复制
case "checkbox":
            $html .= " 
            <div class='form-check'>
                <input type='checkbox' name='participant_question[]' value='" . $option->value . "' class='form-check-input' ><label class='form-check-label' for='exampleCheck1'>" . $option->value . "</label>
            </div>";

这将输出以下html:

代码语言:javascript
复制
<div class="checkbox-group required">   
  <div class="form-check">
    <input type="checkbox" name="participant_question[]" value="whatever" class="form-check-input"><label class="form-check-label" for="exampleCheck1">whatever</label>
  </div>
  <div class="form-check">
    <input type="checkbox" name="participant_question[]" value="whatever2" class="form-check-input"><label class="form-check-label" for="exampleCheck1">whatever2</label>
  </div>
</div>

然后在提交时,我不知道您是否使用ajax完成此操作,但我假设您不是这样做的,所以如果您在表单-> id="questionForm"中添加id

代码语言:javascript
复制
$('#questionForm').submit(function() {
    if($('div.checkbox-group.required div :checkbox:checked').length > 0) {
        return true;//submit the form
    } else {
        return false; // do not submit the form
    }
});

不幸的是,只有使用 html5才能实现你想要的东西,无论你选择什么解决方案,都可能要用js来完成。
