Drupal: Create custom search
- by Dr. Hfuhruhurr
I'm trying to create a custom search but getting stuck.
What I want is to have a dropdownbox so the user can choose where to search in.
These options can mean 1 or more content types.
So if he chooses options A, then the search will look in node-type P,Q,R.
But he may not give those results, but only the uid's which will be then themed to gather specific data for that user.
To make it a little bit clearer, Suppose I want to llok for people. The what I'm searching in is 2 content profile types. But ofcourse you dont want to display those as a result, but a nice picture of the user and some data.
I started with creating a form with a textfield and the dropdown box.
Then, in the submit handler, i created the keys and redirected to another pages with those keys as a tail. This page has been defined in the menu hook, just like how search does it.
After that I want to call hook_view to do the actual search by calling node_search, and give back the results.
Unfortunately, it goes wrong. When i click the Search button, it gives me a 404.
But am I on the right track? Is this the way to create a custom search?
Thx for your help.
Here's the code for some clarity:
<?php
// $Id$
/*
* @file
* Searches on Project, Person, Portfolio or Group.
*/
/**
* returns an array of menu items
* @return array of menu items
*/
function vm_search_menu() {
$subjects = _vm_search_get_subjects();
foreach ($subjects as $name => $description) {
$items['zoek/'. $name .'/%menu_tail'] = array(
'page callback' => 'vm_search_view',
'page arguments' => array($name),
'type' => MENU_LOCAL_TASK,
);
}
return $items;
}
/**
* create a block to put the form into.
* @param $op
* @param $delta
* @param $edit
* @return mixed
*/
function vm_search_block($op = 'list', $delta = 0, $edit = array()) {
switch ($op) {
case 'list':
$blocks[0]['info'] = t('Algemene zoek');
return $blocks;
case 'view':
if (0 == $delta) {
$block['subject'] = t('');
$block['content'] = drupal_get_form('vm_search_general_form');
}
return $block;
}
}
/**
* Define the form.
*/
function vm_search_general_form() {
$subjects = _vm_search_get_subjects();
foreach ($subjects as $key => $subject) {
$options[$key] = $subject['desc'];
}
$form['subjects'] = array(
'#type' => 'select',
'#options' => $options,
'#required' => TRUE,
);
$form['keys'] = array(
'#type' => 'textfield',
'#required' => TRUE,
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Zoek'),
);
return $form;
}
function vm_search_general_form_submit($form, &$form_state) {
$subjects = _vm_search_get_subjects();
$keys = $form_state['values']['keys']; //the search keys
//the content types to search in
$keys .= ' type:' . implode(',', $subjects[$form_state['values']['subjects']]['types']);
//redirect to the page, where vm_search_view will handle the actual search
$form_state['redirect'] = 'zoek/'. $form_state['values']['subjects'] .'/'. $keys;
}
/**
* Menu callback; presents the search results.
*/
function vm_search_view($type = 'node') {
// Search form submits with POST but redirects to GET. This way we can keep
// the search query URL clean as a whistle:
// search/type/keyword+keyword
if (!isset($_POST['form_id'])) {
if ($type == '') {
// Note: search/node can not be a default tab because it would take on the
// path of its parent (search). It would prevent remembering keywords when
// switching tabs. This is why we drupal_goto to it from the parent instead.
drupal_goto($front_page);
}
$keys = search_get_keys();
// Only perform search if there is non-whitespace search term:
$results = '';
if (trim($keys)) {
// Log the search keys:
watchdog('vm_search', '%keys (@type).', array('%keys' => $keys, '@type' => $type));
// Collect the search results:
$results = node_search('search', $type);
if ($results) {
$results = theme('box', t('Zoek resultaten'), $results);
}
else {
$results = theme('box', t('Je zoek heeft geen resultaten opgeleverd.'));
}
}
}
return $results;
}
/**
* returns array where to look for
* @return array
*/
function _vm_search_get_subjects() {
$subjects['opdracht'] =
array('desc' => t('Opdracht'),
'types' => array('project')
);
$subjects['persoon'] =
array('desc' => t('Persoon'),
'types' => array('types_specialisatie', 'smaak_en_interesses')

$subjects['groep'] =
array('desc' => t('Groep'),

$subjects['portfolio'] =
