生成 HTML 以显示具有正确类型（文本、复选框等）的自定义问题，并正确添加所需属性

我有一个表单供用户创建自定义问题。为此，用户需要引入问题（例如：你的手机是什么？）以及字段的类型（文本，长文本，复选框，选择菜单，单选按钮）。如果用户选中复选框、菜单或单选按钮的字段，他还需要介绍问题的可用选项。

在数据库中，问题入到问题和question_options表中，如下所示：

问题表：

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：

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：

   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，我想在视图注册中正确显示.php输入（文本，单选按钮，复选框，选择，文本区域和输入文件）基于问题表的列“类型”中存储的类型。如果数据透视表中的必需列为“1”，则还要添加必需的属性。

当问题的类型为文本，单选按钮，选择，文本区域或文件时，它工作正常，所需的属性被添加到表单字段中。

但是它不能与复选框一起正常工作，因为在复选框的情况下，如果问题是复选框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（）时，为每个复选框输入生成的html都需要为复选框生成，因此用户需要选中所有复选框：

 <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>

您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，因此用户应至少选中1个复选框，但不应意味着用户需要选中所有复选框。

而且你知道怎么做，如果需要自定义问题，在每个问题标签内添加这个“”？<span class="text-primary">*</span>

问题模型中的 GetHtmlInput（）：

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（）使用如下：

@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 HTML：

<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[]">

    <input type="hidden" value="6" name="participant_question_id[]">
  </div>

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

此外，在HTML验证器（如w3c验证器）中检查此表单时，会出现一些错误：

标签元素的 for 特性必须引用非隐藏窗体控件。在“文本”中
标签元素的 for 特性必须引用非隐藏窗体控件。在“检查”中
标签元素的 for 特性必须引用非隐藏窗体控件。在“检查1”中

答案 1

这是因为您的循环中有复选框组 html：foreach

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

您需要考虑如何使用类似变量的方法来解决这个问题，并在函数开始时将其设置为0，当大小写为复选框时，递增变量，然后回显组div。$checkboxesFound$checkboxesFound == 0

答案 2

将 getHtmlInput（）替换为 this

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" : "") . ">";


                break;

            case "long_text":
                $html .= "

            <textarea name='participant_question[".$question_id."][".$index_position."]' class='form-control' rows='3'" . ($required ? " required" : "") . ">"
                    . $name .
                    "</textarea>";

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

和

刀片代码与此

@if ($allParticipants == 0)
{{ $index_position = 0 }}
@foreach($selectedRtype['questions'] as $customQuestion)

   {{ $question_id = [[QUESTION_ID]] }}

    <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(
                $question_id,
                $index_position,
                $customQuestion->name,
                $customQuestion->options,
                ($customQuestion->pivot->required == '1'),
                'form-control',
                $customQuestion->type)
            !!}

        @else
            {!! $customQuestion->getHtmlInput(
                $question_id,
                $index_position,
                $customQuestion->name,
                [],
                ($customQuestion->pivot->required == '1'),
                'form-control',
                $customQuestion->type)
            !!}
        @endif
    </div>
    {{ $index_position = $index_position+1 }}
@endforeach
@endif

您需要将name属性设置为与同一组选项相同，以便正确使用所需的选项。

但在代码中，所有选项（包括不同选项组）都共享相同的名称属性。

上述代码未经测试。但我希望它能为你工作
