variable_set，鉤塊和鉤菜單保存配置值，然後打印出的自定義模板

Question

我想 1）實現塊勾了勾菜單和variable_set並徵求並從用戶存儲的配置值， 2 ）然後使用檢索配置值和 3）當頁面顯示時，使用主題鉤將它們傳遞到模板中。

但是，我需要在第二步和第三步中推動一下！

// ===================== file: my_module.php 

function my_module_block($op = 'list', $delta = 0, $edit = array()) 
{ 
switch($op) 
{ 
    case 'list': 
    $blocks[0] = array(
    'info' => t('Find Something'), // required value - this shows up in your list of blocks 
    'region' => 'left',    // default region on the page 
    'weight' => 0,     // position the block vertically within its column. 
    'visibility' => 1,    // permit the block to be displayed for a given user. 
    'status' => TRUE, // enabled 
    ); 
    return $blocks; 
    break; 

    // case configure 
    case 'configure': 
    // not used ? 

    // case save (save configuration values) 
    case 'save': 
    variable_set('my_module_text_bottom', $edit['my_module_text_bottom']); 
    variable_set('my_module_text_top', $edit['my_module_text_top']);

Answer 1

我調整了一下你的代碼，有一些評論。希望能幫助你。

function my_module_theme(){ 
return array(
    'my_module_show' => array(
    'arguments' => array('text1' => NULL, 'text' => NULL), // define all arguments, no values required, keys serve as labels in theme function/template  
    'template' => 'my_module_show' 
), 
); 
} 


function my_module(){ 
$output = ''; 

//use variable_get 
$text1 = variable_get('my_module_text_top', ''); 
$text2 = variable_get('my_module_text_bottom', ''); 

$output .= theme('my_module_show', $text1, $text2); //pass values as arguments to theme functions 
return $output; 
}
