I have 3 fields in my database and I want to add data by row-wise, please help me to add this data in the database.
Use this example for insert json data into database table
$data = array(
'name'=>$this->input->post('name'),
'mobile'=>$this->input->post('phone_number'),
'email'=>$this->input->post('email'),
'message'=>$this->input->post('message'),
'contact_for'=>$this->input->post('user_type'),
'ip_address'=>$this->input->ip_address(),
'browser_info'=>$this->agent->browser().' - '.$this->agent->version(),
);
$json = json_encode($data);
$insertField = array('json_field' => $json);
$this->db->insert('tbl_name', $insertField);
if ($this->db->affected_rows() > 0) {
$insert_id = $this->db->insert_id();
return $insert_id;
}
return false;
You can use
$json = json_encode($data);
https://www.php.net/manual/en/function.json-encode.php
$response = array('status' => 'OK');
$this->output
->set_status_header(200)
->set_content_type('application/json', 'utf-8')
->set_output(json_encode($response, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES))
->_display();
exit;

In this code, I have two different tables i.e. skill_master and jobs_category. Now, I want to get these two different table data into one and also convert its data into JSON format using json_encode.
$this->db->select('category');
$this->db->from('jobs_category');
$this->db->order_by('category');
$query1 = $this->db->get();
$result1 = $query1->result_array();
$this->db->select('key_skills');
$this->db->from('skill_master');
$this->db->order_by('key_skills');
$query2 = $this->db->get();
$result2 =$query2->result_array();
$arr = array();
foreach($result1 as $row)
{
foreach($result2 as $rows)
{
$arr[] = $row['category'].','.$rows['skill_master'];
}
}
$json = json_encode($arr);
echo $json;
For example:
table1: skill_master
key_skills
==========
java
php
dot net
table2: jobs_category
category
========
IT Jobs
Air line Jobs
Hardware Jobs
Now, Here I have two tables here. Now, I want to combine these two tables and want data in JSON format like ["java", "PHP", "dot net", "IT Jobs", "Air Line Jobs", "Hardware Jobs"]. So, How can I do this? Please help me.
Thank You
$this->db->select('category');
$this->db->from('jobs_category');
$this->db->order_by('category');
$query_category= $this->db->get();
$result_category = $query_category->result_array();
$this->db->select('key_skills');
$this->db->from('skill_master');
$this->db->order_by('key_skills');
$query_skills = $this->db->get();
$result_skills =$query_skills->result_array();
If You get records from table jobs_category and skill_master like this
$result_category =
[
'0' => ['category' => 'IT Jobs'],
'1' => ['category' => 'Air line Jobs'],
'2' => ['category' => 'Hardware Jobs']
];
$result_skills =
[
'0' => ['skill_master' => 'java'],
'1' => ['skill_master' => 'php'],
'2' => ['skill_master' => 'dot net']
];
$final_arr = $final_category_arr = $final_skill_arr = [];
foreach($result_category as $category_row)
{
$final_category_arr[] = $category_row['category'];
}
foreach($result_skills as $skill_row)
{
$final_skill_arr[] = $skill_row['skill_master'];
}
$final_arr = array_merge($final_category_arr, $final_skill_arr);
$json = json_encode($final_arr);
echo $json;
Result will be like this
["IT Jobs","Air line Jobs","Hardware Jobs","java","php","dot net"]
renaming column while fetching and merging data should work. try following code
$this->db->select('category');
$this->db->from('jobs_category');
$this->db->order_by('category');
$query_category= $this->db->get();
$result_category = $query_category->result_array();
$this->db->select('key_skills as category');
$this->db->from('skill_master');
$this->db->order_by('key_skills');
$query_skills = $this->db->get();
$result_skills =$query_skills->result_array();
$result = array_merge($result_category,$result_skills);
I'm trying to save data in CakePHP in this way:
get max entry_id from table translations
(SELECT MAX(entry_id) as res FROM translations) + 1
save data into translations table
$translationData = array('entry_id' => $entry_id, 'language_id' => $key, 'text' => $item);
$translation = new Translation();
$translation->set($translationData);
$translation->save();
again get max entry_id
save next set of data
again get max entry_id
save next set of data
Please have a look at my code:
$this->request->data['Product']['name_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['name']);
$this->request->data['Product']['description_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['description']);
$this->request->data['Product']['seo_title_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['seo_title']);
$this->request->data['Product']['seo_keywords_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['seo_keywords']);
$this->request->data['Product']['seo_desc_tr_id'] = $this->Translation->saveTranslations($this->request->data['Product']['seo_desc']);
saveTranslations method:
public function saveTranslations($data) {
$entry_id = $this->getNextFreeId();
foreach($data as $key => $item) {
if($item != "") {
$this->create();
$temp['Translation']['entry_id'] = $entry_id;
$temp['Translation']['language_id'] = $key;
$temp['Translation']['text'] = $item;
$this->save($temp);
}
}
return $entry_id;
}
getNextFreeId method:
public function getNextFreeId() {
$result = $this->query("SELECT MAX(entry_id) as res FROM translations");
return $result[0][0]['res'] + 1;
}
I don't know why entry_id have all the time the same value.
After many hours of searching for solution I finally managed to solve the problem in very easy way - just add false parameter in query method:
$this->query("INSERT INTO translations(entry_id, language_id, text) VALUES($entry_id, $key, '$item')", false);
and
$result = $this->query("SELECT SQL_CACHE MAX(entry_id) as res FROM translations", false);
I'm trying to create a Joomla module that displays articles based on categories and tags.
I've taken code for selecting tagged articles from https://github.com/lasinducharith/joomla-tags-selected) and introduced it into a copy of mod_articles_news:
public static function getList(&$params)
{
$app = JFactory::getApplication();
$db = JFactory::getDbo();
// Code base on https://github.com/lasinducharith/joomla-tags-selected to fetch ids of tagged articles
$tagsHelper = new JHelperTags;
$tagIds = $params->get('tagid', array());
$tagIds = implode(',', $tagIds);
echo '<pre>search for tags[' . $tagIds . ']';
$query=$tagsHelper->getTagItemsQuery($tagIds, $typesr = null, $includeChildren = false, $orderByOption = 'c.core_title', $orderDir = 'ASC',$anyOrAll = true, $languageFilter = 'all', $stateFilter = '0,1');
$db->setQuery($query, 0, $maximum);
$results = $db->loadObjectList();
$article_ids=array();
foreach ($results as $result){
$article_ids[]=$result->content_item_id;
}
echo ' yields articles[' . implode(',', $article_ids ) . ']</pre>';
// Get an instance of the generic articles model
$model = JModelLegacy::getInstance('Articles', 'ContentModel', array('ignore_request' => true));
// Set application parameters in model
$appParams = JFactory::getApplication()->getParams();
$model->setState('params', $appParams);
// Set the filters based on the module params
$model->setState('list.start', 0);
$model->setState('list.limit', (int) $params->get('count', 15));
$model->setState('filter.published', 1);
$model->setState('list.select', 'a.fulltext, a.id, a.title, a.alias, a.introtext, a.state, a.catid, a.created, a.created_by, a.created_by_alias,' .
' a.modified, a.modified_by, a.publish_up, a.publish_down, a.images, a.urls, a.attribs, a.metadata, a.metakey, a.metadesc, a.access,' .
' a.hits, a.featured' );
// Access filter
$access = !JComponentHelper::getParams('com_content')->get('show_noauth');
$authorised = JAccess::getAuthorisedViewLevels(JFactory::getUser()->get('id'));
$model->setState('filter.access', $access);
// Category filter
$model->setState('filter.category_id', $params->get('catid', array()));
// Article filter
$model->setState('filter.id', $article_ids);
// Filter by language
$model->setState('filter.language', $app->getLanguageFilter());
// Set ordering
$ordering = $params->get('ordering', 'a.publish_up');
$model->setState('list.ordering', $ordering);
if (trim($ordering) == 'rand()')
{
$model->setState('list.direction', '');
}
else
{
$direction = $params->get('direction', 1) ? 'DESC' : 'ASC';
$model->setState('list.direction', $direction);
}
// Retrieve Content
$items = $model->getItems();
$newitems=array();
foreach ($items as &$item)
{
echo '<pre>fetched article[' . $item->id .'] which is ';
if ( !in_array($item->id, $article_ids )){
echo 'not tagged';
} else{
echo 'tagged';
}
echo '</pre>';
...
}
return $newitems;
}
The debug statements give me:
search for tags[2] yields articles[40,44,45]
fetched article[45] which is tagged
fetched article[44] which is tagged
fetched article[43] which is not tagged
fetched article[42] which is not tagged
fetched article[41] which is not tagged
fetched article[40] which is tagged
fetched article[39] which is not tagged
fetched article[38] which is not tagged
So the articles have not been filtered by id. I'd be very grateful for any advice.
Thanks
Found the problem, the filter should be article_id:
// Article filter
$model->setState('filter.article_id', $article_ids);
Now it selects articles based on tags and categories
I need perform query "LOCK TABLE myTable WRITE"
<?php
$db = Database::instance();
$query = 'LOCK TABLE `myTable` WRITE';
$db->query(Database::WHAT_IS_THE_TYPE_SHOULD_SPECIFY_HERE_?, $query);
In framework Kohana 3.3
file ~/modules/database/classes/Kohana/Database.php
implements folowing types:
const SELECT = 1;
const INSERT = 2;
const UPDATE = 3;
const DELETE = 4;
but none of them fit in my case.
Any idea. Thanks.
Google works wonders. http://forum.kohanaframework.org/discussion/6401/lockunlock/p1
You can pass NULL as the first argument:
$db = Database::instance();
$query = 'LOCK TABLE `myTable` WRITE';
$db->query(NULL, $query);
From Kohana: http://kohanaframework.org/3.3/guide-api/Database_MySQL#query
if ($type === Database::SELECT)
{
// Return an iterator of results
return new Database_MySQL_Result($result, $sql, $as_object, $params);
}
elseif ($type === Database::INSERT)
{
// Return a list of insert id and rows created
return array(
mysql_insert_id($this->_connection),
mysql_affected_rows($this->_connection),
);
}
else
{
// Return the number of rows affected
return mysql_affected_rows($this->_connection);
}
As you can see that's why you're able to pass NULL.
I am using the csvUpload behavior of the Utils plugin by CakeDC, on a CakePHP 2.2.1 install.
I have it working great it's processing a rather large csv successfully. However there are two fields in my table / Model that would be considered fixed, as they are based on ID's from from associated models that are not consistent. So I need to get these fixed values via variables which is easy enough.
So my question is, how do I use the fixed fields aspect of csvUpload? I have tried that following and many little variation, which obviously didn't work.
public function upload_csv($Id = null) {
$unique_add = 69;
if ( $this->request->is('POST') ) {
$records_count = $this->Model->find( 'count' );
try {
$fixed = array('Model' => array('random_id' => $Id, 'unique_add' => $unique_add));
$this->Model->importCSV($this->request->data['Model']['CsvFile']['tmp_name'], $fixed);
} catch (Exception $e) {
$import_errors = $this->Model->getImportErrors();
$this->set( 'import_errors', $import_errors );
$this->Session->setFlash( __('Error Importing') . ' ' . $this->request->data['Model']['CsvFile']['name'] . ', ' . __('column name mismatch.') );
$this->redirect( array('action'=>'import') );
}
$new_records_count = $this->Model->find( 'count' ) - $records_count;
$this->Session->setFlash(__('Successfully imported') . ' ' . $new_records_count . ' records from ' . $this->request->data['Model']['CsvFile']['name'] );
$this->redirect(array('plugin'=>'usermgmt', 'controller'=>'users', 'action'=>'dashboard'));
}
}
Any help would be greatly appreciated as I have only found 1 post concerning this behavior when I searching...
I made my custom method to achieve the same task. Define the following method in app\Plugin\Utils\Model\Behavior
public function getCSVData(Model &$Model, $file, $fixed = array())
{
$settings = array(
'delimiter' => ',',
'enclosure' => '"',
'hasHeader' => true
);
$this->setup($Model, $settings);
$handle = new SplFileObject($file, 'rb');
$header = $this->_getHeader($Model, $handle);
$db = $Model->getDataSource();
$db->begin($Model);
$saved = array();
$data = array();
$i = 0;
while (($row = $this->_getCSVLine($Model, $handle)) !== false)
{
foreach ($header as $k => $col)
{
// get the data field from Model.field
$col = str_replace('.', '-', trim($col));
if (strpos($col, '.') !== false)
{
list($model,$field) = explode('.', $col);
$data[$i][$model][$field] = (isset($row[$k])) ? $row[$k] : '';
}
else
{
$col = str_replace(' ','_', $col);
$data[$i][$Model->alias][$col] = (isset($row[$k])) ? $row[$k] : '';
}
}
$is_valid_row = false;
foreach($data[$i][$Model->alias] as $col => $value )
{
if(!empty($data[$i][$Model->alias][$col]))
{
$is_valid_row = true;
}
}
if($is_valid_row == true)
{
$i++;
$data = Set::merge($data, $fixed);
}
else
{
unset($data[$i]);
}
}
return $data;
}
And you can use it using:
$csv_data = $this->Model->getCSVData($this->request->data['Model']['CsvFile']['tmp_name'], $fixed);
Here $csv_data will contain an array of all of those records from the csv file which are not empty and with the fixed field in each record index.
So as I was telling Arun, I answered my own question and figured it out. I was looking to broad instead of really examining what was in front of me. I started running some debugging and figured it out.
First of all, $unique_add = 69 is seen as an int, duh. In order for it to be added to the csv it need to viewed as a string. So it simply becomes, $unique_add = '69'.
I couldn't enter the value of $Id directly into the fixed array. So I just had to perform a simple find to get the value I needed.
$needed_id = $this->Model->find('first', array(
'condition'=>array('Model.id'=>$Id)
)
);
$random_id = $needed_id['Model']['id'];
Hopefully this won't be needed to help anyone because hopefully no one else will make this silly mistake. But one plus... Now there's actually more than one post on the internet documenting the use of fixed fields in the CakeDC Utils plugin.
