I’m trying to implement a simple search into an application, but not sure of the best way to handle this. My database contains a Listings object which includes City field. I want to create a search form where the user inputs a city into a text field and gets all of the Listings for that city on the next page. I don’t want to perform a full-text search, just the query on that City field.
Also, on the results page, I’d like to store the query in POST and can’t figure out the best way to do this.
What is the best way to approach this in the controller?
Well your view would look something like this
$this->Form->Create('Listing', array('action'=>'search'));
$this->Form->input('city', array('default'=>$city));
$this->Form->end();
if (isset($listings)) {
//code to display listings
}
This view would create the correct form. And your controller needs to get that value
function search() {
$city = '';
if (!empty($this->data)) {
$city = $this->data['Listing']['city'];
$opts = array(
'conditions' => array('Listing.city' => $city)
);
$listings = $this->Listing->find('all', $opts);
$this->set('listings', $listings);
}
$this->set('city', $city); // so the keyword is saved. Can also get it via $this->data
}
This code should give you an idea on how to do this.
This is a great tutorial with a CakePHP search plugin tutorial. You can download the full working code as well from github (w/ MySQL dump).
View:
<?php echo $this->Form->create()
echo $this->Form->input('search');
?>
<input name="data[Product][word]" />
controller:
<?php
$result = $this->Product->find('all',array(
'conditions'=>array(
'OR'=>array(
array('name LIKE'=>'%'.$word.'%'),
array('description LIKE'=>'%'.$word.'%')))));
$this->set(compact('result'));
?>

I would like to customize my template for Joomla 3.7 so that I can use the new feature of Joomla 3.7, Custom fields (com_fields), and display and format them via CSS in my template where I need to display them.
Can someone suggest me the PHP code I should use in the template to display field(s), some example please.
Thanks in advance.
For everyone getting late to the party. In case you want to use your custom form fields in a Module-Override (which really are the only way to modify j!-templates, so google 'joomla template override') you can use this handy snippet:
<?php
JLoader::register('FieldsHelper', JPATH_ADMINISTRATOR . '/components/com_fields/helpers/fields.php');
$jcFields = FieldsHelper::getFields('com_content.article', $item, true);
$itemCustomFields = array();
foreach($jcFields as $field) {
$itemCustomFields[$field->name] = $field->rawvalue;
}
?>
Now you cna use your customfields like so: itemCustomFields['customFieldName1']
Haven't tested in article overrides. May soon, if so, this will get updated.
certainly not the right way to do it but I had the same need and I found a work around based on https://www.giudansky.com/news/12-coding/146-joomla-custom-fields
Copie default.php from /components/com_content/views/article/tmpl/default.php to
templates/YOUR_THEME/html/com_content/article/default.php
Add following code line 25 :
$myCustomFields = array();
foreach($this->item->jcfields as $field) {
$myCustomFields[$field->name] = $field->value;
}
$GLOBALS['myCustomFields'] = $myCustomFields;
Typically you put on a global var the content of fields attached to your article.
On your template page you can know retrieved value of your field.
just print_r($GLOBALS['myCustomFields']); to view the content of your array.
That will do the trick waiting for a better answer..
This is absolutely the wrong way to do this I think but I was tearing my hair out so i came up with this quick db query to return custom field values in the template. surely this violates some kind of joomla protocol?
obviously this assumes you can get $articleid into your template already which is the Current ID of your article.
I too am waiting on a better solution but hope this helps
$db =& JFactory::getDBO();
$sql = "select * from #__fields_values where `item_id` = $articleid";
$db->setQuery($sql);
$fieldslist = $db->loadObjectList();
echo $fieldslist[0]->value;
echo $fieldslist[1]->value;
echo $fieldslist[your field ID here]->value;
I found it was easiest to follow how com_fields does it in its rendering code. In Joomla!3.7+, you'll find it in [joomla_root]/components/com_fields/layouts/fields/render.php .
Here are the main parts you need to reproduce the formatting that Joomla has:
JLoader::register('FieldsHelper', JPATH_ADMINISTRATOR . '/components/com_fields/helpers/fields.php');
<dl class="fields-container">
<?php foreach ($this->item->jcfields as $field) : ?>
<?php // If the value is empty do nothing ?>
<?php if (!isset($field->value) || $field->value == '') : ?>
<?php continue; ?>
<?php endif; ?>
<?php $class = $field->params->get('render_class'); ?>
<dd class="field-entry <?php echo $class; ?>">
<?php echo FieldsHelper::render($context, 'field.render', array('field' => $field)); ?>
</dd>
<?php endforeach; ?>
</dl>
This loops through all available tags for the component or article. The nice thing about this method is it still applies the render classes you include with the fields.
Make sure to set Automatic Display to Do not automatically display on your fields; otherwise you will see them twice on your page view.
If you want to just target specific fields to show, you can use the name of the field to target it. (The label and value pair is underneath.) See the field Joomla docs for more info.
I implemented this small function to get specific custom field values:
function getCustomFieldValue($field_name, $article_id, $default_value = '') {
// Load custom field list
$fields = FieldsHelper::getFields('com_content.article', $article_id, true);
$field_ids = array_column($fields, 'id', 'name');
$model = JModelLegacy::getInstance('Field', 'FieldsModel', array('ignore_request' => true));
// Return the value if the field exists, otherwise the default
return array_key_exists($field_name, $field_ids)
? $model->getFieldValue($field_ids[$field_name] , $article_id)
: $default_value;
}
Usage:
$some_field_value = getCustomFieldValue('some-field-name', $some_article_id);
Optimization: I placed the function into a helper class, implemented the variables $fields, $field_ids and $model static and checked if they are already loaded to prevent redundant loading of the same data.
I have asked this question before but i did not get the right answer. I have a table 'cv', i want to search for items in the database using two fields i.e. course and location, the two items are on the same table('cv'). I dont have an idea on how to implement the two searches.
The code below is for displaying search for course only and its working fine. Help me to use the two search criterions i.e.course and location or in other words how do i add the search for location input in my code.
Controller
function search_worker()
{
$data['query']=$this->kint_model->search_workers($this->input->post('search'));
$this->load->view('hire_display',$data);
}
Model
function search_workers($search)
{
return $query = $this->db->get_where('cv', array('course '=> $search))->result();
}
View
$data = array('name'=>'search', 'id'=>'search','value'=>'bcom');
echo form_input($data);
$data = array('name'=>'submit', 'id'=>'submit', 'value'=>'Search Item(s)');
echo form_submit($data);
Maybe you need a like clause in your query,
function search_workers($search){
//return $query = $this->db->get_where('cv', array('course '=> $search))->result();
return $this->db->like('course', $search)->like('location', $location)->get('cv')->result();
}
You should also get some basic SQL training.
I am trying to build in a "search" box on a results page in my cakephp app. The page uses the cakePHP pagination component to show and "page" results. This is perfect, but I am having difficulties to get the next part to work.
The desired outcome:
A cakephp form (post) with an input box and a couple of select boxes, including a date selector so that I can select between dates. The user should be able to populate these fields and submit
On submit, the user selection should change the cakePHP pagination conditions in the controller
In the view I want the pagination bar to keep record of the user selection, so that when I filter through different pages, it keeps the users search. I understand this can be achieved using $this->passedArgs, hence why I am using post and not get.
The code:
// Form:
<?php
echo $this->Form->create('search', array('class' => false));
echo $this->Form->input('searchFor');
echo $this->Form->input('dateFrom');
echo $this->Form->input('dateTo');
echo $this->Form->end();
?>
// Controller:
if($this->request->is("post")) {
$filters = $this->request->data["search"];
$this->passedArgs["searchFor"] = $filters["searchFor"];
$this->passedArgs["dateFrom"] = $filters["dateFrom"]." 00:00:00";
$this->passedArgs["dateTo"] = $filters["dateTo"]." 00:00:00";
// Assign search parameters:
if($this->passedArgs["searchFor"] != "") {
$conditions["Model.field LIKE"] = "%".$this->passedArgs["searchFor"]."%";
}
$conditions["Model.created >="] = $this->passedArgs["dateFrom"];
$conditions["Model.created <="] = $this->passedArgs["dateTo"];
} else {
$conditions = array("Result.status_id >=" => 12);
}
$this->paginate = array(
'conditions' => $conditions,
'order' => array('Result.created ASC'),
'limit' => 20
);
$this->set("results",$this->paginate("Model");
// The view file:
<?php
$this->Paginator->options(array('url' => $this->passedArgs));
?>
Where I am now:
The initial page loads with all of the results
When I populate the search boxes it does return my results
The problem:
I am convinced the way I am doing it is incorrect as I now need to do 2 checks, a) being if results has been posted and b) check if there is passedArgs available. I am 100% convinced this is not the right way of doing it.
Let's say I have 2 free form fields for search, say name and surname, if I leave surname blank my url would be written as below, and this does not look or appear to be correct. That means I have to assign default values to ensure the items below does not happen, which does not appear to be very dynamic.
http://localhost/site/controller/action/surname:0/name:John/date:0/
On refresh it says the page does not exist because the posted values is not available anylonger.
usually I proceed like this in the controller:
//transform POST into GET
if($this->request->is("post")) {
$url = array('action'=>'index');
$filters = array();
if(isset($this->data['searchFor']) && $this->data['searchFor']){
//maybe clean up user input here??? or urlencode??
$filters['searchFor'] = $this->data['searchFor'];
}
//redirect user to the index page including the selected filters
$this->redirect(array_merge($url,$filters));
}
$conditions = array();
//check filters on passedArgs
if(isset($this->passedArgs["searchFor"])){
$conditions["Model.field LIKE"] = "%".$this->passedArgs["searchFor"]."%";
}
//paginate as normal
$this->paginate = array(
'conditions' => $conditions,
'order' => array('Result.created ASC'),
'limit' => 20
);
The idea is to transform the POST sent by your form into GET. so you wont have problems with the paginator nor the refresh
Hope this helps
What you want can be done a lot more simple and DRY by using this search plugin.
It automates what you want more or less plus it already can do more than your code.
So I suggest you to use the plugin directly or take a look at it how it does the trick. :)
I have a template file that I want to print a the cck user reference form field on.
Is this possible? Note, this is not the field value, but the field form. Also asking for just the field, not creating a form first and then using drupal_get_form()
Thanks!
Edit: If this is not possible that's fine too, I just would like to know
Edit2: i just need the autocomplete mechanism so I can grab the uid in js from searching for the username
If you just need autocomplete mechanism I would suject you to use jQuery autocomplete plugin - http://docs.jquery.com/Plugins/autocomplete.
you can just output in the template something like that:
print '<input type="text" id="user-autocomplete">';
Then in javascript code
$(document).ready('function(){
$('#user-autocomplete').autocomplete(some-ajax-url-here)
}');
you also will need to create an ajax callback page somewhere in your module:
function YOUR_MODULE_NAME_menu(){
$items = array();
$items['user-autocomplete-ajax-page'] = array(
'title' => 'AJAX:get user',
'page callback' => 'get_user'
);
}
function get_user(){
$sql = 'SELECT uid, name FROM {users} WHERE name LIKE ("%s")';
$result = db_query($sql,$_GET['request']);
$res_str = '';
while($object = db_fetch_object($result)){
$res_str .= $object->name.' ['.$object->uid."]\n";
}
print $res_str;
}
I didn't test the code, but I guess it should work, may be with some minor changes.
I am modifying an already contributed drupal module (Inline Ajax Search) to handle searching of a specific content type with some search filters (i.e. when searching for help documentation, you filter out your search results by selecting for which product and version of the product you want help with).
I have modified the module some what to handle all the search filters.
I also added in similar functionality from the standard core search module to handle the presenting of the search form and search results on the actual search page ( not the block form ).
The problem is that when i submit the form, i discovered that I'd lose all my post data on that submit because somewhere, and i don't know where, drupal is either redirecting me or something else is happening that is causing me to lose everything in the $_POST array.
here's the hook_menu() implementation:
<?php
function inline_ajax_search_menu() {
$items = array();
$items['search/inline_ajax_search'] = array(
'title' => t('Learning Center Search'),
'description' => t(''),
'page callback' => 'inline_ajax_search_view',
'access arguments' => array('search with inline_ajax_search'),
'type' => MENU_LOCAL_TASK,
'file' => 'inline_ajax_search.pages.inc',
);
}
?>
the page callback is defined as such (very similar to the core search module's search_view function):
<?php
function inline_ajax_search_view() {
drupal_add_css(drupal_get_path('module', 'inline_ajax_search') . '/css/inline_ajax_search.css', 'module', 'all', FALSE );
if (isset($_POST['form_id'])) {
$keys = $_POST['keys'];
// Only perform search if there is non-whitespace search term:
$results = '';
if(trim($keys)) {
require_once( drupal_get_path( 'module', 'inline_ajax_search' ) . '/includes/inline_ajax_search.inc' );
// Collect the search results:
$results = _inline_ajax_search($keys, inline_ajax_search_get_filters(), "page" );
if ($results) {
$results = theme('box', t('Search results'), $results);
}
else {
$results = theme('box', t('Your search yielded no results'), inline_ajax_search_help('inline_ajax_search#noresults', drupal_help_arg()));
}
}
// Construct the search form.
$output = drupal_get_form('inline_ajax_search_search_form', inline_ajax_search_build_filters( variable_get( 'inline_ajax_search_filters', array() ) ) );
$output .= $results;
return $output;
}
return drupal_get_form('inline_ajax_search_search_form', inline_ajax_search_build_filters( variable_get( 'inline_ajax_search_filters', array() ) ) );
}
?>
from my understanding, things should work like this: A user goes to www.mysite.com/search/inline_ajax_search and drupal will process the path given in my url and provide me with a page that holds the themed form for my search module. When i submit the form, whose action is the same url (www.mysite.com/search/inline_ajax_search), then we go thru the same function calls, but we now have data in the $_POST array and one of them is indeed $_POST['form_id'] which is the name of the form "inline_ajax_search_search_form". so we should be able to enter into that if block and put out the search results.
but that's not what happens...somewhere from when i submit the form and get my results and theme it all up, i get redirected some how and lose all my post data.
if anybody can help me, it'd make me so happy lol.
drupal_get_form actually wipes out the $_POST array and so that's why I lose all my post data.
according to this: http://drupal.org/node/748830 $_POST should really be ignored when doing things in drupal. It's better to find a way around using it. One way is the way described in the link, making ur form data persist using the $_SESSION array. I'm sure there are various other and better ways to do this, but yeah, drupal_get_form was the culprit here...
