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

Question

我有一个表单供用户创建自定义问题。为此，用户需要引入问题（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，问题插入到问题和问题选项表中，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 

注册\类型\问题透视表：

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，我想在视图中正确显示registration.blade.php输入（文本、单选按钮、复选框、选择、文本区域和输入文件）基于存储在问题表的类型列中的类型。如果数据透视表中所需的列是“1”，还可以添加所需的属性。

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

但是它不能正确地使用复选框，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，那么这意味着用户需要回答该问题，但不意味着用户需要选中所有复选框。

问题是，使用函数getHTMLInput（）生成的html复选框在每个复选框输入中都需要，因此用户需要检查所有复选框：

 <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？当需要自定义问题时，这意味着需要该问题，因此用户应至少选择一个复选框，但不意味着用户需要选中所有复选框。

如果需要自定义问题，您是否知道如何在每个问题标签中添加此“

GetHtmlInput（）在问题模型中：

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（）如下所示：

@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（）生成超文本标记语言：

<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，在超文本标记语言验证器（如w3c验证器）中检查此表单会出现一些错误：

• label元素的for属性必须引用非隐藏的表单控件。在“文本”中




Answer 1

HTML5没有一个解决方案来实现需要一组复选框，因此通过一些更改您可以实现它。首先，在控制器上，您需要对其进行更改，以实现与选择菜单相同的效果。

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

然后在复选框的情况下，您只需要打印所需复选框组中的选项：

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：

<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，但我假设您没有，所以如果您在表单中添加id-

$('#questionForm').submit(function() {
    if($('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，只使用html5是不可能实现你想要的，无论你选择什么解决方案，它都可能必须用js来完成。

将getHtmlInput（）替换为以下内容

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;
}

@endif

您需要将同一组选项的name属性设置为相同，以便正确使用所需选项。

但在代码中，包括不同选项组的所有选项都共享相同的名称属性。

以上代码未经测试。但我希望它对你有用

Answer 3

这是因为在您的Foreach循环中有一个复选框组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于$checkboxesFound的变量，并在函数开头将其设置为0，当case为checkbox时，增加变量，如果$checkboxesFound==0，则回显组div。
