Question

我想生成一个带有最后一个选项的无线电组，带有输入字段文本的单选按钮，如果需要，此类还必须生成没有此输入字段的无线电组。这是班级：

class Radio extends \PFBC\OptionElement {
    protected $_attributes = array("type" => "radio", "class" => "custom");
    protected $inline;
        protected $_hasOtherTextfield;

  public function __construct($label, $name, $properties, $hasOtherTextfield) {
    $this->_hasOtherTextfield = $hasOtherTextField;
    parent::__construct($label, $name, $properties);
  }

    public function render() { 
        $labelClass = $this->_attributes["type"];
        if(!empty($this->inline))
            $labelClass .= " inline";

        $count = 0;
        foreach($this->options as $value => $text) {
            $value = $this->getOptionValue($value);

            echo '<div class="radio"><label class="form-control', $labelClass . '"> <input id="', $this->_attributes["id"], '-', $count, '"', $this->getAttributes(array("id", "value", "checked")), ' value="', $this->filter($value), '"';
            if(isset($this->_attributes["value"]) && $this->_attributes["value"] == $value)
                echo ' checked="checked"';
            echo '/> ', $text, ' </label></div> ';
            ++$count;
        }   

    if ($this->hasOtherTextField) {
    echo '<div class="radio"><label class="form-control', $labelClass . '"> <input id="', $this->_attributes["id"], '-', $count, '"', $this->getAttributes(array("id", "value", "checked")), ' value="', $this->filter($value), '"';
            if(isset($this->_attributes["value"]) && $this->_attributes["value"] == $value)
                echo ' checked="checked"';
            echo '/> ', $text, ' </label></div>';

      echo '<input type="text" name=""/>';
    }
    }
}

这是OptionElement类：

abstract class OptionElement extends Element {
    protected $options;

    public function __construct($label, $name, array $options, array $properties = null) {
        $this->options = $options;
        if(!empty($this->options) && array_values($this->options) === $this->options)
            $this->options = array_combine($this->options, $this->options);

        parent::__construct($label, $name, $properties);
    }

    protected function getOptionValue($value) {
        $position = strpos($value, ":pfbc");
        if($position !== false) {
            if($position == 0)
                $value = "";
            else
                $value = substr($value, 0, $position);
        }
        return $value;
    }
}

在这里我创建了一个广播组：

$form->addElement(new Element\Radio("My Selected Radio Buttons", "Radio", array("Option #1", "test"),  true //this will be the last option to generate radio with input));

所以在这段代码中我有一个错误：

Notice: Undefined variable: hasOtherTextField in

和

Notice: Undefined property: PFBC\Element\Radio::$hasOtherTextField

Answer 1

Radio Radio tmethod render中的小错误。

第一个错误（变量名称区分大小写！）：

使用

$this->_hasOtherTextfield = $hasOtherTextfield;

而不是

$this->_hasOtherTextfield = $hasOtherTextField;

第二个错误（错误的变量名称）：使用

if ($hasOtherTextField) { ... }

或者

if ($this->_hasOtherTextField) { ... }

而不是

if ($this->hasOtherTextField) {

需要帮助来修复将生成无线电组的类
