我是cakePhp的新手，我在调用公共变量时遇到问题，要在我的add.ctp中显示

下面的

是模型文件夹中的我的province.php：

<?php
App::uses('AppModel', 'Model');
App::uses('Sanitize', 'Utility');
/**
 * Place Model
 *
 */
class Province extends AppModel {

/**
 * Display field
 *
 * @var string
 */

    public $continent = array(
        'AF' => 'Africa',
        'AS' => 'Asia',
        'EU' => 'Europe',
        'NA' => 'North America',
        'SA' => 'South America',
        'OC' => 'Oceania',
        'AN' => 'Antartica'
    );

    public $countries = array(
            'Asia' => array(
                'AF' => 'Afghanistan',  
                'AM' => 'Armenia',  
                'AZ' => 'Azerbaijan',   
                'BH' => 'Bahrain',
                'BD' => 'Bangladesh',
                'BT' => 'Bhutan',
                'BN' => 'Brunei',   
                'KH' => 'Cambodia',
                'CN' => 'China',
                'CX' => 'Christmas Island',
                'CC' => 'Cocos Islands',
                'IO' => 'Diego Garcia',
                'GE' => 'Georgia',
                'HK' => 'Hong Kong',
                'IN' => 'India',
                'ID' => 'Indonesia',
                'IR' => 'Iran',
                'IQ' => 'Iraq',
                'IL' => 'Israel',
                'JP' => 'Japan',
                'JO' => 'Jordan',
                'KZ' => 'Kazakhstan',
                'KP' => 'North Korea',
                'KR' => 'South Korea',
                'KW' => 'Kuwait',
                'KG' => 'Kyrgyzstan',
                'LA' => 'Laos',
                'LB' => 'Lebanon',
                'MO' => 'Macau',
                'MY' => 'Malaysia',
                'MV' => 'Maldives',
                'MN' => 'Mongolia',
                'MM' => 'Myanmar',
                'NP' => 'Nepal',
                'OM' => 'Oman',
                'PK' => 'Pakistan',
                'PS' => 'Palestine',
                'PH' => 'Philippines',
                'QA' => 'Qatar',
                'SA' => 'Saudi Arabia',
                'SG' => 'Singapore',
                'LK' => 'Sri Lanka',
                'SY' => 'Syria',
                'TW' => 'Taiwan',
                'TJ' => 'Tajikistan',
                'TH' => 'Thailand',
                'TR' => 'Turkey',
                'TM' => 'Turkmenistan',
                'AE' => 'United Arab Emirates',
                'UZ' => 'Uzbekistan',
                'VN' => 'Vietnam',
                'YE' => 'Yemen',
            )
        );

    public $belongsTo = array(
        'Image' => array(
            'className' => 'Image',
            'foreignKey' => 'image_id'
        ),
    );

}

这是省控制器的代码：

<?php
App::uses('AppController', 'Controller');
App::uses('Sanitize', 'Utility');
/**

}

这是我的观点add.ctp：

<div class="places form box-rounded">
<div class="pull-right">
    <?php echo $this->Html->link('View', 'view/' .$this->request->data['Province']['id']) ?>
</div>
<?php if(!empty($this->request->data)): ?>
<h2><?php echo __('Edit Province'); ?></h2>
<?php else: ?>
<h2><?php echo __('New Province'); ?></h2>
<?php endif; ?>

<?php 

    echo $this->Form->create('Province', array('type' => 'file', 'inputDefaults' => array('class' => 'form-control', 'div' => array('class' => 'col-sm-3'))));

    echo "<div class='form-group row'>" . $this->Form->input('name') . "</div>"; 
    echo "<div class='form-group row'>" . $this->Form->input('country', array('options' => $countries,
        'label' => _('Country'),
    )) . "</div>";

    debug($countries); exit;
    echo "<div class='form-group row'>" . $this->Form->input('region') . "</div>";
?>

    <fieldset>
        <legend>Image</legend>
        <?php
        echo '<div class="row"><div class="col-sm-12">Current: ';
        if (isset($this->request->data['Province']['image_id']) && $this->request->data['Province']['image_id']) {
            $url = $s3->get_url($this->request->data['Image']['filename'], 'preview');
            echo $this->Html->image($url, array("class" => 'img-rounded')); 
        }
        echo "</div></div>";
        ?>
        <?php
        echo "<div class='form-group row'>" . $this->Form->input('img', array(
            'label' => __('Upload'),
            'type' => 'file',
            'class' => ''
        )) . "</div>";
        echo "<div class='form-group row'>" . $this->Form->input('img_title', array(
            'label' => __('Image Title'),
            'value' => @$this->request->data['Image']['title']
        )) . "</div>";
        echo "<div class='form-group row'>" . $this->Form->input('img_desc', array(
            'label' => __('Describe'),
            'value' => @$this->request->data['Image']['description']
        )) . "</div>";

        ?>
        <fieldset>
            <legend>Image Attribution</legend>
        <?php
        echo "<div class='form-group row'>" . $this->Form->input('img_source', array(
            'label' => __('Source URL'),
            'value' => @$this->request->data['Image']['source_url']
        )) . "</div>";
        echo "<div class='form-group row'>" . $this->Form->input('img_source_name', array(
            'label' => __('Source Name'),
            'value' => @$this->request->data['Image']['source_name']
        )) . "</div>";
        ?>
        </fielset>

    </fielset>

    <?php 
        $options = array(
            'label' => 'Save',
            'escape' => false,
            'class' => 'btn btn-success'
        ); 
    ?>

    <?php echo $this->Form->end($options); ?>

这就是我得到的：

'<div class="col-sm-3"><label for="ProvinceCountry">Country</label><select name="data[Province][country]" class="form-control" maxlenght="15" id="ProvinceCountry">

选项没有出现。我在这里错过了什么吗？我想在模型中显示$ countries变量作为选择框中的选项。谢谢。

答案 0 :(得分：3)

在控制器的代码中使用以下代码：

$this->set('countries', $this->Province->countries['Asia']);

或

$this->set('countries', $this->Province->countries[$this->Province->continent['AS']]);

现在，您将能够在视图文件中访问$countries变量。
