Question

我正在使用cakephp 3创建搜索表单，我必须使用单选按钮。

我不知道如何使用php制作它们。这就是我到目前为止所做的：

＆＃13;

input[type=radio] + label:before {
  display: inline-block;
  vertical-align: middle;
  margin: -2px 8px 0 0;    
  height: 23px;  
  width: 23px;  
  
  border-radius: 50%;
  border: 2px solid #777;
  
  background-color: #fff;
  background-clip: padding-box;
  
  content: "";  
  transition: box-shadow .01s .39s ease-in-out, background .4s ease-in-out;

}

input[type=radio]:checked + label:before {  
  box-shadow: inset 0 0 0 2px #fff;
  border: solid #F44336;
  background-color: #F44336;  
  transition: background .4s ease-in-out;
}

＆＃13;

<div class="col-sm-3 text-center">
              <input type="radio" name="radio" id="radio1" value="1">
              <label for="radio1">Product Shots</label>
          </div>
          <div class="col-sm-3 text-center">
              <input type="radio" name="radio" id="radio3" value="3">
              <label for="radio3">Video</label>
          </div>
          <div class="col-sm-3 text-center"> 
              <input type="radio" name="radio" id="radio2" value="2">
              <label for="radio2">Printing Materials</label>
          </div>

＆＃13;

标签旁边的单选按钮不会显示：

          <div class="col-sm-3 text-center"> 
        <?= $this->Form->input('multimedia_type_id', ['type' => 'radio', 
                                                      'name' => 'radio',
                                                      'label' => false,
                                                      'options' => $multimediaTypes
                                                     ]); ?>
      </div>

Answer 1

在CAKEPHP3中创建无线电按钮，

语法为：

value

label - 表示选中此单选按钮时的值。
hiddenField - 布尔值，表示是否为小部件标签应该显示。
radio() - 布尔值，表示您是否希望disabled的结果包含值为''的隐藏输入。这对于创建不连续的无线电设备非常有用。
empty - 设置为true或禁用以禁用所有单选按钮。
empty - 设置为true以创建值为''作为第一个选项的输入。如果为真，则无线电标签将为“echo $this->Form->radio( 'favorite_color', [ ['value' => 'r', 'text' => 'Red', 'style' => 'color:red;'], ['value' => 'u', 'text' => 'Blue', 'style' => 'color:blue;'], ['value' => 'g', 'text' => 'Green', 'style' => 'color:green;'], ] ); // Will output <input type="hidden" name="favorite_color" value=""> <label for="favorite-color-r"> <input type="radio" name="favorite_color" value="r" style="color:red;" id="favorite-color-r"> Red </label> <label for="favorite-color-u"> <input type="radio" name="favorite_color" value="u" style="color:blue;" id="favorite-color-u"> Blue </label> <label for="favorite-color-g"> <input type="radio" name="favorite_color" value="g" style="color:green;" id="favorite-color-g"> Green </label>”。将此选项设置为字符串以控制标签值。

一般来说，$ options是一个简单的密钥=＆gt;价值对。但是，如果您需要在单选按钮上放置自定义属性，则可以使用扩展格式：

new YourAsyncTask().execute("String1","String2","12");
