我是模块开发领域的初学者,我面临着一个问题。我已经创建了带有hook_menu函数的.module文件,其中包含以下代码:
$items['game/add_tournament/view_tournament']=array(
'title'=>'View Tournament',
'description'=>'Tournament View',
'page callback'=>'game_view_tournament_page',
'access callback' => 'user_access',
);
My Page回调如下:-
function game_view_tournament_page() {
$header_table_edit = array(
// first cell has the following text 'Title'
array('data' => t('Tournament Name')),
// second cell has the following text 'Link to edit'
array('data' => t('No of Weeks')),
array('data' => t('Start Date')),
array('data' => t('End Date')),
array('data' => t('Edit'))
);
$query = db_query
( "select tournament_id ,tournament_name ,tournament_no_of_weeks ,tournament_start_date ,tournament_end_date from {tournaments} ");
while ($data = db_fetch_object($query))
{
$rows_table_edit[] = array(
array('data' => l($data->tournament_name, 'game/add_tournament/view_tournament/' . $data -> tournament_id)),
array('data' => t($data->tournament_no_of_weeks)),
array('data' => t($data->tournament_start_date)),
array('data' => t($data->tournament_end_date)),
array('data' => l(t('Edit'),'game_tournament_edit/'.$data -> tournament_id.'/edit')) );
}
$caption_table_edit = t('Table for edit nodes');
return theme('table', $header_table_edit, $rows_table_edit);
}
到目前为止,网站运行良好。现在问题来了。在这一点上,我假设另一个回调将被调用,当我点击编辑按钮,回调也应该在我的hook_menu函数中注册。在这里,我不知道这个方法是否被回调。因为每次我点击编辑按钮,我得到一个页面没有发现错误。以下是回调
$items['game_week_edit/%game_abc/edit']=array(
'type' => MENU_LOCAL_TASK,
'access arguments' => array('access content'),
'page callback' => 'game_week_edit_page',
'page arguments' => array(1),
);
// The above code is in hook_menu function and the following code is outside hook_menu . Let me know if i am doing anything wrong.
function game_week_edit_page($abc_id){
return drupal_get_form('game_week_edit_form',$abc_id);
}
function game_week_edit_form( &$form_state, $abc_id) {
$form = array();
$options = array();
$sql = "SELECT game_week_id,tournament_id,start_time,open_time,close_time FROM {game_week} where game_week_id='$abc_id'";
$r = db_query($sql);
$sql_tournament = "SELECT tournament_name FROM {tournaments} ";
$r_tournament = db_query($sql_tournament);
while ($row = db_fetch_array($r_tournament)) {
$options[$row['tournament_name']] = $row['tournament_name'];
}
while ($row = db_fetch_object($r))
{
$form['tournament_name'] = array(
'#type' => 'select',
'#required'=>true,
'#title' => t('Select Tournament'),
'#options' => $options,
'#weight'=>1,
'#description' => t('<br>'),
);
$form['start_time'] = array(
'#type' => 'textfield',
'#required'=>true,
'#value'=>t($row->start_time),
'#title' => t('Enter Start Time'),
'#size'=>40,
'#maxlength'=>128,
'#weight'=>2,
'#description' => t('Please enter start time.'),
);
$form['open_time'] = array(
'#type' => 'textfield',
'#required'=>true,
'#value'=>t($row->open_time),
'#title' => t('Enter Tournament Start Time'),
'#size'=>40,
'#maxlength'=>128,
'#weight'=>3,
'#description' => t('Booking open time.'),
);
$form['close_time'] = array(
'#type' => 'textfield',
'#required'=>true,
'#value'=> t($row->close_time),
'#title' => t('Booking close time'),
'#size'=>40,
'#maxlength'=>128,
'#weight'=>4,
'#description' => t('Booking close time.'),
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Update Tournament'),
'#weight'=>5
);
}
return $form;
}
在hook_menu中,尽量不要在编辑项中命名通配符。"%game_abc"告诉Drupal调用一个函数"game_abc_load"(即"_load"所附加的名称),并使用返回值作为页面回调"game_week_edit_page"的第一个参数。如果没有这样的功能,就会出现问题。
在这种情况下,看起来您只想传递整数id,在这种情况下,您可以使用"%"。
