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

Question

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

在数据库中,问题被插入问题和question_options表中,如:

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   

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registration.blade.php中正确显示输入(文本,单选按钮,复选框,选择,文本区域和输入文件),基于存储在问题表的"类型"列中的类型.如果数据透视表中的必需列为"1",还要添加必需的属性.

当问题属于文本类型,单选按钮,选择,文本区域或文件时,它正常工作,所需的属性将添加到表单字段中.

但是它与复选框无法正常工作,因为在复选框的情况下,如果问题是复选框类型,并且需要提出的问题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检查所有复选框.

问题是,使用函数getHTMLInput(),每个复选框输入都需要生成的复选框html,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>

你知道如何解决这个问题吗？如果需要自定义问题,则表示问题是必需的,因此用户应选择至少1个复选框,但不应表示用户需要选中所有复选框.

而且你也知道如何,如果需要自定义问题,请在每个问题标签中添加这个" <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;
    }
}

然后使用getHtmlInput(),如:

@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[]">
  </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HTML验证器(如w3c验证器)中检查此表单时,会出现一些错误:

• label元素的for属性必须引用非隐藏的表单控件.在"文本
• label元素的for属性必须引用非隐藏的表单控件.在"Checkb"中
• label元素的for属性必须引用非隐藏的表单控件.在"check1"中
• label元素的for属性必须引用非隐藏的表单控件.在"check2"中
• label元素的for属性必须引用非隐藏的表单控件.在"rad1
• label元素的for属性必须引用非隐藏的表单控件.在"rad2
• label元素的for属性必须引用非隐藏的表单控件.在"选择"
• label元素的for属性必须引用非隐藏的表单控件.在"textar"中
• label元素的for属性必须引用非隐藏的表单控件.在"文件

Answer 1

这是因为你在foreach循环中有复选框组html :

 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来解决这个问题,$checkboxesFound并在函数开始时将其设置为0,当case为复选框时,增加变量,$checkboxesFound == 0然后回显组div.

Answer 2

用这个替换你的getHtmlInput()

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

刀片代码用这个

@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

您需要设置相同组选项的名称属性,以便正确地处理所需的选项.

但是在您的代码中,包括不同选项组在内的所有选项都共享相同的名称属性.

以上代码未经过测试.但我希望它对你有用
