我正在使用drupal form api並使用複選框。我在使用默認檢查值時遇到問題。以下是代碼片段...drupal form api複選框

$result = db_query("SELECT nid, filepath FROM {content_type_brand}, {files} WHERE content_type_brand.field_brand_image_fid 
= files.fid"); 
     $items = array(); 
     while ($r = db_fetch_array($result)) { 
       array_push($items, $r); 
     } 
     $options = array(); 
     foreach($items as $i) { 
      $imagePath = base_path().$i['filepath']; 
      $options[$i['nid']] = '<img src="'.$imagePath.'"></img>'; 
     } 
     $form['favorite_brands'] = array (
      '#type' => 'fieldset', 
      '#title' => t('Favorite Brands'), 
      //'#weight' => 5, 
      '#collapsible' => TRUE, 
      '#collapsed' => FALSE, 
     ); 
     $form['favorite_brands']['brands_options'] 
= array(
      '#type' => 'checkboxes', 
      '#options' => $options, 
      '#default_value' => $options_checked,// $options_checked is an array similar to $options but having elements which need to be checked by default... 
      '#multicolumn' => array('width' => 3) 
     ); 

但價值不被默認選中...誰能幫我缺少的是什麼?

其中是$ options_checked定義? 問題是提供的代碼片段沒有以任何方式定義$ options_checked,因此默認情況下沒有複選框被選中 – zerolab 2011-02-25 02:12:10

你$ options_checked陣列不應該在相同的格式爲您的$ options數組。你的$ options數組包含nid => img標籤對。您的$ options_checked數組應該只包含默認應選中的選項的nid值:

$options_checked = array(8,17);
