I have this php function in codeigniter where it fetches the data from my database:
function fetch_data()
{
$data = $this->projectionchart_model->make_query();
$array = array();
foreach($data as $row)
{
$array[] = $row;
}
$output = array(
'current' => intval($_POST["current"]),
'rowCount' => 10,
'total' => intval($this->projectionchart_model->count_all_data()),
'rows' => $array
);
echo json_encode($output);
}
I want to use the number_format function to some of columns and right now it's building everything in an array. How could I remove the array and list the data individually as variables so I can apply a function to some of them and then output them?
Thank you
Edit: explaining in more detail
This function fetch_data() calls the make_query() function stored in the projectionchart_model file which contains the following:
function make_query()
{
if(isset($_POST["rowCount"]))
{
$this->records_per_page = $_POST["rowCount"];
}
else
{
$this->records_per_page = 10;
}
if(isset($_POST["current"]))
{
$this->current_page_number = $_POST["current"];
}
$this->start_from = ($this->current_page_number - 1) * $this->records_per_page;
$this->db->select("*");
$this->db->from("projection_chart");
if(!empty($_POST["searchPhrase"]))
{
$this->db->like('ae', $_POST["searchPhrase"]);
$this->db->or_like('client', $_POST["searchPhrase"]);
$this->db->or_like('product', $_POST["searchPhrase"]);
$this->db->or_like('week_of', $_POST["searchPhrase"]);
$this->db->or_like('month', $_POST["searchPhrase"]);
$this->db->or_like('type', $_POST["searchPhrase"]);
}
if(isset($_POST["sort"]) && is_array($_POST["sort"]))
{
foreach($_POST["sort"] as $key => $value)
{
$this->db->order_by($key, $value);
}
}
else
{
$this->db->order_by('id', 'DESC');
}
if($this->records_per_page != -1)
{
$this->db->limit($this->records_per_page, $this->start_from);
}
$query = $this->db->get();
return $query->result_array();
}
So the output currently is this:
I want to format the Planned Spend, Cleared and Total Commission with the number_format php function but right now it's all in an array.
How could I accomplish this?

Am trying to update multiple records in the database but my case I have a column total, which I want to update to different values. I haven't tried much here but hope I could get a clue on how to go about this.
My controller
public function update_record()
{
$id = ["19821", "19923", "19966", "19967"];
$total = ["8", "118", "90", "100"];
if ($this->some_model->batch_data('records', $total, $id) == true) {
echo "yes";
} else {
echo "no";
}
}
The Model
public function batch_data($table, $data, $where)
{
$this->db->where_in('id',$where);
$this->db->set('total',$data);
$this->db->update($table);
return true;
}
I have not tested this yet but currently looking for a more and efficient way of doing this.
If you still want to update multiple records using the update_batch method, you could first assign the id and total as key-value arrays, then use the update_batch method.
Controller :
public function update_record()
{
$id = ["19821", "19923", "19966", "19967"];
$total = ["8", "118", "90", "100"];
$update_data = [];
foreach ($id as $key => $value) {
$update_data[] = [
'id' => $value,
'total' => $total[$key]
];
}
if ($this->some_model->batch_data('records', $update_data) == true) {
echo "yes";
} else {
echo "no";
}
}
Model :
public function batch_data($table, $data)
{
$this->db->update_batch($table, $data, 'id'); // this will set the id column as the condition field
return true;
}
Output :
// preview query output :
// UPDATE `records`
// SET
// `total` =
// CASE
// WHEN `id` = '19821' THEN 8
// WHEN `id` = '19923' THEN 118
// WHEN `id` = '19966' THEN 90
// WHEN `id` = '19967' THEN 100
// ELSE `total`
// END
// WHERE `id` IN ('19821', '19923', '19966', '19967')
As per my comment. This is a method that combines the array in to key/value pairs and updates them 1x1 wrapped in a transaction (so if one query fails nothing changes).
This is the method I would personally use as I don't like update_batchs internal workings (cases).
$id = ["19821", "19923", "19966", "19967"];
$total = ["8", "118", "90", "100"];
$combined = array_combine($id, $total);
if (count($combined) > 0) {
$this->db->trans_start();
foreach ($combined as $id => $total) {
$this->db->set('total', $total);
$this->db->where('id', $id);
$this->db->update('sometable');
}
$this->db->trans_complete();
return $this->db->trans_status();
}
return true;
Try this, Only for single where condition
Controller:
public function update_record()
{
$tableName = "records";
$id = ["19821", "19923", "19966", "19967"];
$total = ["8", "118", "90", "100"];
$update_data = [];
foreach ($id as $key => $value) {
$update_data[] = [
'id' => $value,
'total' => $total[$key]
];
}
$whereKey = 'id';
$this->$this->some_model->batch_data($tableName, $updateData, $whereKey);
}
Model:
public function batch_data($tableName, $updateData, $whereKey)
{
$this->db->update_batch($tableName, $updateData, $whereKey);
}
I am using Codeigniter to fetch rows. Please go through the below code.
//Model
public function selectData() {
$query = $this->db->query('SELECT * FROM tbl_favourites WHERE favourites_status = 1');
$count = $query->num_rows();
if($count > 0)
return $result = $query->result_array();
else
return 0;
}
//Controller
$all_favourites = $this->select->selectData();
if(!empty($all_favourites)) {
foreach($all_favourites as $favourites)
echo json_encode($favourites);
}
From the above code, the output is
{"favourite_online_id":"3","favourite_online_url":"ddd","favourite_online_status":"0"}
{"favourite_online_id":"2","favourite_online_url":"http:\/\/www.google.com","favourite_online_status":"0"}
But I want the output to be formatted properly to satisfy the android JSON.
The required output is,
[
{
"favourite_online_id": "3",
"favourite_online_url": "ddd",
"favourite_online_status": "0"
},
{
"favourite_online_id": "2",
"favourite_online_url": "http://www.google.com",
"favourite_online_status": "0"
}
]
instead of using
if(!empty($all_favourites)) {
foreach($all_favourites as $favourites)
echo json_encode($favourites);
}
use directly
if(!empty($all_favourites)) {
echo json_encode($all_favourites );
}
I think you can modify your function
public function selectData() {
$query = $this->db->query('SELECT * FROM tbl_favourites WHERE favourites_status = 1');
$count = $query->num_rows();
if($count > 0)
return $result = $query->result_array();
else
return array();
}
//Controller
$all_favourites = $this->select->selectData();
// if(!empty($all_favourites)) {
// foreach($all_favourites as $favourites)
// echo json_encode($favourites);
// }
echo json_encode($all_favourites);
You can do in 2 way
1st way
if(!empty($all_favourites)) {
echo json_encode($all_favourites);
}
2nd way
if you want to add something in that object then
$favouriteArray=[];
if(!empty($all_favourites)) {
foreach($all_favourites as $favourites){
array_push($favouriteArray, $favourites);
}
}
echo json_encode($favouriteArray);
I wanting to be able to join two tables togeather.
How ever because I my forum table has column "name" and my forum_categories column "name"
I am not able to display both names.
On my select() if I use like $this->db->select('f.name, fc.name', false); it only displays name from forum_categories
array(1) { [0]=> array(1) { ["name"]=> string(17) "News & Discussion" } }
Question how can I get both names to show from both columns and
tables.
Note: I only want to be able to use $result['name'] in my foreach loop.
So the out put I would like it to be
General
News & Discussion
Lounge

update
works fine with code below but would rather just use one lot of join()
public function get_forums() {
$this->db->select("*");
$this->db->from('forum');
$query = $this->db->get();
foreach ($query->result_array() as $f) {
$data[] = array(
'name' => $f['name']
);
$this->db->select("*");
$this->db->from('forum_categories');
$query = $this->db->get();
foreach ($query->result_array() as $fc) {
$data[] = array(
'name' => $fc['name']
);
}
}
return $data;
}
Try This , It Will Work .
public function get_forums() {
$this->db->select('f.name as forum_name, fc.name as forum_categories_name', false);
$this->db->from('forum f');
// tried $this->db->join('forum_categories fc', 'fc.forum_id = f.forum_id');
$this->db->join('forum_categories fc', 'fc.forum_categories_id = f.forum_id');
$query = $this->db->get();
if ($query->num_rows() > 0) {
return $query->result_array();
} else {
return false;
}
}
From what i see in your updated question. What you need is UNION and not JOIN. You can use get_compiled_select() to build both query before concat with UNION.
public function get_forums() {
$forum = $this->db->select('name')->get_compiled_select('forum');
$forum_categories = $this->db->select('name')->get_compiled_select('forum_categories');
$query = $this->db->query($forum.' UNION '.$forum_categories);
if ($query->num_rows() > 0) {
return $query->result_array();
} else {
return false;
}
}
Simply use
AS
keyword, because when you try to print it, that AS keyword give you optional name for your column.
Here i have two table which have same column name "name" so i have changed those with AS keyword.
Ex:
$this->db->select('tbl_category.id_category,tbl_category.name AS cat_name,
tbl_subject.id_subject,tbl_subject.name AS sub_name');
In result
Array ( [0] => Array ( [id_category] => 9 [cat_name] => OL [id_subject] => 13 [sub_name] => Science )
So it is simple solution from the SQL language
I have two tables sport_tbl, match_tbl. In sport_tbl, i defined sport_name such as cricket. In match_tbl, I have match_name,match_date,sport_id.
I want to show match_date of every sport_name (ex. i am showing match_date list for cricket sport and i want to show every date has match_name list).
I want to show one distinct match_date.
Image
my controller code:-
$url = 'cricket' // for example first sport_name
$data['getSportMatch'] = $this->user_model->getSportMatch($url);
my model code:-
public function getSportMatch($sport)
{
$query = $this->db->get_where('match_tbl',array('sport_name' => $sport));
if($query->num_rows > 0)
{
foreach($query->result() as $item){
$data[] = $item;
}
return $data;
}
}
my code in view:-
<div><?php foreach($getSport as $item): ?><h4><?= $item->sport_name; ?></h4><div><?= foreach($getSportMatch as $item): ?>
match_date)) ?>here i want to show list match_name of every match_date
My table structure images
1) sport_tbl
2) match_tbl
3) another match_tbl
you can solve this in model easily. if i did not understand wrong . you need 2 function in model.
1. will get sport names
2. will get matches of given sport name
//model functions
function get_sports(){
$data = array();
$sports = $this->db->select('sport_name')->from('sport_tbl')->get()->result();
if($sports)
{
foreach($sports as $sport){
$data[$sport->sport_name] = $this->get_matches($sport->sport_name);
}
return $data;
}
}
function get_matches($sport_name){
$matches = $this->db->select('*')->from('match_tbl')->where('sport_name',$sport_name)->get()->result();
return $matches;
}
so in view data will be something like this
$data => array(
'cricket'=> array(0 => array(
'match_id' => 11,
'sport_id' = 2 .....
)))
Try this coding ...
public function getSportMatch($sport)
{
$query = $this->db->query("SELECT * FROM sport_tbl as st INNER JOIN match_tbl as mt ON st.sport_id = mt.sport_id WHERE st.sport_name ='".$sport."'");
if($query->num_rows > 0)
{
$query_result = $query->result_array();
$final_result = array();
foreach($query_result as $result ) {
$date = $result['match_date'];
$final_result[$date][] = $result;
}
return $final_result;
}
}
View Coding :-
if(isset($final_result)) {
foreach($final_result as $result) {
echo $result['match_date']; // First display match date
if(isset($result['match_date'])) {
foreach($result['match_date'] as $match) {
echo $match['match_name']; // Second listout the match name
}
}
}
}
I need to set the pagination order of my register based on field ($results[$key]['Movimento']['status']) created in afterFind callback.
afterFind:
public function afterFind($results, $primary = false) {
foreach ($results as $key => $val) {
if(isset($val['Movimento']['data_vencimento'])) {
$data = $val['Movimento']['data_vencimento'];
$dtVc = strtotime($data);
$dtHj = strtotime(date('Y-m-d'));
$dtVencendo = strtotime("+7 day", $dtHj);
if ($dtVc < $dtHj) {
$results[$key]['Movimento']['status'] = 'vencido';
} elseif ($dtVc <= $dtVencendo) {
$results[$key]['Movimento']['status'] = 'vc15dias';
} else {
$results[$key]['Movimento']['status'] = 'aberto';
}
}
if(isset($val['Movimento']['data_pagamento'])) {
$results[$key]['Movimento']['status'] = 'quitado';
}
}
return $results;
Pagination:
$options = array(
...
'order' => array('Movimento.status' => 'ASC')
);
$this->controller->paginate = $options;
$movimentos = $this->controller->paginate('Movimento');
I know this does not work because the field is created after the paginator call.
Can I make it work?
as I understand, you want to sort by data_pagamento and than by data_vencimento (has it the mysql-type date?)
so you don't need your afterFind-function for ordering, simply use:
'order' => array(
'Movimento.data_pagamento DESC',//first all rows with not-empty data_pagamento
'Movimento.data_vencimento DESC',// first all dates in the furthest future
)
