我有一个表格供用户创建自定义问题。为此,用户需要介绍问题(例如:您的手机是什么?)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、选择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,问题被插入到 questions 和 question_options 表中,例如:
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 View 中,我想在 View registration.blade.php 中正确显示基于存储在“类型”列中的类型的输入(文本、单选按钮、复选框、选择、文本区域和输入文件)问题表。如果数据透视表中的必填列为“1”,则还要添加必填属性。
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,必填属性将添加到表单字段中。
但它不适用于复选框,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检查所有复选框。
问题在于,使用函数 getHTMLInput() 生成的复选框 html 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,这意味着该问题是必需的,因此用户应至少选择 1 个复选框,但不应意味着用户需要选中所有复选框。
如果需要自定义问题,您知道如何在每个问题标签内添加“<span class="text-primary">*</span>
”吗?
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 $html;
}
}
然后 getHtmlInput() 的用法如下:
@if ($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[]">
</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)中检查此表单会出现一些错误:
- 标签元素的for属性必须引用非隐藏的表单控件。在“文
- label元素的for属性必须引用一个非隐藏的表单控件。在“检查b”中
- 标签元素的for属性必须引用非隐藏的表单控件。在“检查1”中
- 标签元素的for属性必须引用非隐藏的表单控件。在“check2”中
- 标签元素的for属性必须引用非隐藏的表单控件。在“rad1
- label元素的for属性必须引用一个非隐藏的表单控件。在“rad2
- label元素的for属性必须引用一个非隐藏的表单控件。在“选择”中
- 标签元素的for属性必须引用非隐藏的表单控件。在“文本”中
- 标签元素的for属性必须引用非隐藏的表单控件。在“文件
最佳答案
这是因为在此处的 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" : "") . ">
您需要考虑如何解决这个问题,也许可以使用 $checkboxesFound
之类的变量,并在函数开始时将其设置为 0,当 case 为复选框时,增加变量,然后如果 $checkboxesFound == 0
然后回显组 div。
