使用自定义模块,显示结果,
function searchsong_block($op='list',$delta=0){
$block = array();
switch($op){
case "list":
$block[0][info] = t('Search song');
return $block;
case "view":
$block['subject']='THIS IS SONG SEARCH MODULE';
$block['content']=drupal_get_form('custom1_default_form');
return $block;
}
}
function custom1_default_form () {
$form = array();
$form['txt_name'] =
array('#type' => 'textfield',
'#title' => t('Please enter your name'),
'#default_value' => variable_get('webservice_user_url',''),
'#maxlength' => '40',
'#size' => '20',
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Save Details'),
);
return $form;
}
function custom1_default_form_validate (&$form, &$form_state) {
if(($form_state['values']['txt_name']) == '') {
form_set_error('user_webservice', t('Enter a name'));
}
}
function custom1_default_form_submit ($form_id, $form_values) {
$GET_TXT_VAL = $_POST['txt_name'];
$result = db_query('SELECT title FROM {node} WHERE type = "%s" AND title LIKE "%%%s%%"', 'song', $GET_TXT_VAL);
$output='';
while ($row = db_fetch_object($result)) {
// drupal_set_message($row->title);----IF I ENABLE THIS LINE THEN MY SEARCH RESULT DISPLAYING IN THE GREEN BLOCK, YES I KNOW THIS FUNCTION SOMETHING LIKE ECHO JUST FOR TESTING PURPOSE WE SHOULD USE
$output .=$row->title;
}
$block['content'] = $output;
}
如何打印我的输出,
上面的模块不显示任何内容,甚至也显示错误,
我想我应该使用主题('itemlist')一些东西,但我不确定如何使用它,以及我应该在哪里使用它,
那么我应该做什么想要的是,我想显示我的搜索结果,在内容区域,
请在下面找到我的问题图片视图。
function searchsong_block($op='list',$delta=0){
$block = array();
switch($op){
case "list":
$block[0][info] = t('Search song');
return $block;
case "view":
$block['subject']='THIS IS SONG SEARCH MODULE';
$block['content']=drupal_get_form('custom1_default_form');
return $block;
}
}
function custom1_default_form () {
$form = array();
$form['txt_name'] =
array('#type' => 'textfield',
'#title' => t('Please enter your name'),
'#default_value' => variable_get('webservice_user_url',''),
'#maxlength' => '40',
'#size' => '20',
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Save Details'),
);
return $form;
}
function custom1_default_form_validate (&$form, &$form_state) {
if(($form_state['values']['txt_name']) == '') {
form_set_error('user_webservice', t('Enter a name'));
}
}
function custom1_default_form_submit ($form_id, $form_values) {
$GET_TXT_VAL = $_POST['txt_name'];
$result = db_query('SELECT title FROM {node} WHERE type = "%s" AND title LIKE "%%%s%%"', 'song', $GET_TXT_VAL);
$output='';
while ($row = db_fetch_object($result)) {
// drupal_set_message($row->title);----IF I ENABLE THIS LINE THEN MY SEARCH RESULT DISPLAYING IN THE GREEN BLOCK, YES I KNOW THIS FUNCTION SOMETHING LIKE ECHO JUST FOR TESTING PURPOSE WE SHOULD USE
$output .=$row->title;
}
$block['content'] = $output;

验证和提交不是为了输出数据。
您应该以 custom1_default_form 形式显示结果:
添加提交 $_SESSION['search_text'] 或使用多步“存储”(为此学习 drupal 表单 api)。
但让我们看看如何通过会话进行工作:
在custom1_default_form中添加:
您的提交函数应该是这样的:
这就是全部。
提示:
如果需要,则不需要此代码:
请在此处阅读有关表单API的信息:http://api.drupal.org
使用块的其他方式,只需通过 drupal_get_form 调用输出结果和表单的函数即可,因此:
Validate and submit are not for outputting data.
You should show your results in custom1_default_form:
Add in submit $_SESSION['search_text'] or use multistep "storage" (learn drupal form api for this).
But let's look how to work via sessions:
Add in custom1_default_form:
Your submit function should be like this:
This is all.
Tips:
This code is not needed, if you do:
Read please about form api here: http://api.drupal.org
Other way to use block, just call function that output result and form via drupal_get_form, so:
