I guess I'm just looking over it but I can't get my variables to my view.
In the same controller I call a function, from there I return an array containing the variables (also array's). From within the function I originally started I send the variables to the view.
But, in the view I get an error saying the variable is undefined.
The information I need is in array $items and array $trans. These need to get in the function confirmation and end up in the confirmation view.
The two functions (I tried to remove most code that has nothing to do with the question):
public function confirmation($order_id){
$order = Orders::findOrFail($order_id);
if(isset($order->transaction_id)){
$data = [];
$data['order_id'] = $order->order_reference;
$data['trans'] = $order->dat['tr'];
$data['items'] = $order->dat['it'];
return view('confirmation', $data);
}else{
//Nothing relevant
}
}
public function sendpicqer($order_id){
$order = Orders::with(['orderDetails', 'orderAddress', 'customer'])->where('order_id', $order_id)->first();
$order_details = OrderDetails::where('order_id', $order_id)->get();
$error = $order_id;
$result = $this->picqer->addCustomer($customer);
if(!isset($result['data'])){
$error = $result;
if(is_array($result)){
$error = json_encode($result);
}
return redirect()->route('cancel');
}
$orderData = [
'idcustomer' => $result['data']['idcustomer']
];
$orderData['products'] = [];
$items = [];
foreach($order_details as $od){
$pid = $od->product_id;
switch ($pid) {
case 1:
$pid = 2399983;
break;
case 2:
$pid = 2399990;
break;
}
$orderData['products'][] = [
'idproduct' => $pid,
'amount' => $od->quantity
];
$items[] = [
'sku' => $pid,
'name' => $od->product_id->product_name,
'price' => $od->product_id->product_price,
'quantity' => $od->quantity
];
}
$result = $this->picqer->addOrder($orderData);
if(isset($result['data'])){
//Succeeded!
$idorder = $result['data']['idorder'];
$orderid = $result['data']['orderid'];
$trans = array('id' => $orderid, 'affiliation' => 'Matt Sleeps', 'revenue' => $order->total_price);
$dat = [];
$dat['tr'] = $trans;
$dat['it'] = $items;
return $dat;
$result2 = $this->picqer->sendRequest('/orders/'.$idorder.'/process', null, 'POST');
if(!isset($result2['data'])){
$error = $result2;
if(is_array($result2)){
$error = json_encode($result2);
}
return redirect()->route('cancel');
}
}else{
$error = $result;
if(is_array($result)){
$error = json_encode($result);
}
return redirect()->route('cancel');
}
//Order is successfully confirmed and send to Picqer!
$error = '(Both to the customer and with Picqer)';
}
This is the part of view where I need access to the variables:
<?php
var_dump($order_id);
var_dump($trans);
var_dump($items);
// Function to return the JavaScript representation of a TransactionData object.
function getTransactionJs(&$trans) {
return <<<HTML
ga('ecommerce:addTransaction', {
'id': '{$trans['id']}',
'affiliation': '{$trans['affiliation']}',
'revenue': '{$trans['revenue']}'
});
HTML;
}
// Function to return the JavaScript representation of an ItemData object.
function getItemJs(&$transId, &$item) {
return <<<HTML
ga('ecommerce:addItem', {
'id': '$transId',
'name': '{$item['name']}',
'sku' : '{$item['sku']}',
'price': '{$item['price']}',
'quantity': '{$item['quantity']}'
});
HTML;
}
?>
<script>
<?php
echo getTransactionJs($trans);
foreach ($items as &$item) {
echo getItemJs($trans['id'], $item);
}
?>
ga('ecommerce:send');
</script>
You have to send the variables to the view. You could change the code to something like this:
//Return the view via confirmation function.
public function sendpicqer($order_id){
...
return $this->confirmation($order_id, $items, $trans);
}
public function confirmation($order_id, $items, $trans){
$order = Orders::findOrFail($order_id);
if(isset($order->transaction_id)){
$data = [];
$data['order_id'] = $order->order_reference;
$data['trans'] = $trans;
$data['items'] = $items;
//Send the variables to the view
return view('confirmation', $data);
}else{
return redirect()->route('cancel');
}
}
Hope this helps...

I wanted to pass some values to the view.
The $result may be 0 or 1 or '' and I tried to use this below code:
public function whatwedo($result='')
{
$result = array();
$result['status'] = $result;
$this->load->view('admin/whatwedo',$result);
}
public function add_whatwedo()
{
//$this->load->library('form_validation');
$this->form_validation->set_rules('text-input','Title','required');
if($this->form_validation->run() != true)
{
$result = 0;
$this->whatwedo($result);
}
else
{
$this->load->model('admin_model');
$result = $this->admin_model->ins_whatwedo($this->input->post());
//print_r($result);exit();
$this->whatwedo($result);
}
}
And in the view:
<?php
print_r($status);
?>
But, the $status is Array ( )
The problem is this line:
$result = array();
Because now the $result variable is an empty array so when you create the index status on result you assign it an empty array.
To fix you can do something like:
public function whatwedo($input = '')
{
$result['status'] = $input;
$this->load->view('admin/whatwedo', $result);
}
or even...
public function whatwedo($input = '')
{
$this->load->view('admin/whatwedo', ["status" => $input]);
}
This method i am using for storing currentTime in database using ajax call and its working
public function saveTime(Request $request, $lession_id){
$user = Auth::user();
if($user === null){
return response()->json(['message' => 'User not authenticated', 404]);
}
$video = \App\Lession::where('id',$lession_id)->first();
$lesson_id = $request->lession_id;
$progress = $request->time;
//save them somewhere
$watch_history = $user->watch_history;
$watch_history_array = array();
if ($watch_history == '') {
array_push($watch_history_array, array('lession_id' => $lesson_id, 'progress' => $progress));
} else {
$founder = false;
$watch_history_array = json_decode($watch_history, true);
for ($i = 0; $i < count($watch_history_array); $i++) {
$watch_history_for_each_lesson = $watch_history_array[$i];
if ($watch_history_for_each_lesson['lession_id'] == $lesson_id) {
$watch_history_for_each_lesson['progress'] = $progress;
$watch_history_array[$i]['progress'] = $progress;
$founder = true;
}
}
if (!$founder) {
array_push($watch_history_array, array('lession_id' => $lesson_id, 'progress' => $progress));
}
}
$data['watch_history'] = json_encode($watch_history_array);
$check = User::where('id',$user->id)->update(['watch_history' => $watch_history_array]);
return response()->json(['message' => 'Time saved', 200]);//send http response as json back to the ajax call
}
But when I use this another method to get the time back for playback it's getting the array inside an array
public function getTime(Request $request, $lession_id){
$user = Auth::user();
if($user === null){
return response()->json(['message' => 'User not authenticated', 403]);
}
$user_video = User::where('id',$user->id)->first();
$array = $user_video->watch_history;
foreach ($array as $key => $value) {
echo $check;
}
}
My current Output in a database is as follows
[{"lession_id":"157","progress":"71.449464"},{"lession_id":"156","progress":"92.113123"}]
So help me to get the values out of that for each lession id
I am working on a project that gets an array of integers from the api and prints them on the screen. The problem here is, POSTMAN shows that there is data in json format with no errors as shown in the figure but react js says there's no data.

$result = $this->reservation->update('table_name',$update_id, $data);
Model :
$this->db->where($where);
$this->db->update($table, $data);
return $this->db->affected_rows();
I am designing search functionality with some data with Codeigniter.
My search model looks like:
class Search_Model extends CI_Model {
public function get_results($search_terms = false) {
// Build query
foreach ($search_terms as $field => $value) {
$this->db->like("{$field}", $value);
}
// Execute query
$query = $this->db->get('exams');
// Return results
return $query->result_array();
}
}
And the search controller method looks like this:
public function results() {
$search_terms = array(
'first_name' => $this->input->get('first_name', TRUE),
'last_name' => $this->input->get('last_name', TRUE),
'exam_name' => $this->input->get("exam_name", TRUE)
);
$data['title'] = "Search Results";
$data['exams'] = $this->search_model->get_results($search_terms);
$this->load->view('templates/header.php', $data);
$this->load->view('exams/index.php', $data);
$this->load->view('templates/footer.php');
}
The search is working as it should but I want to clean up the URL which comes out something like this if I only search for "First Name":
search/results?first_name=tim&last_name=&exam_name=
How can I remove those extra parameters that are unused in the URL?
The quickest way is just to filter the $searh_terms array before passing it to the model.
$search_terms = array(
'first_name' => $this->input->get('first_name', TRUE),
'last_name' => $this->input->get('last_name', TRUE),
'exam_name' => $this->input->get("exam_name", TRUE)
);
// Remove empty search values
foreach ($search_terms as $key => $value) {
if (strlen($value) == 0) {
unset($search_terms[$key]);
}
}
include jquery in your header. then add this script.
<script>
$(document).ready(function(){
$('#myform').submit(function(event){
event.preventDefault();
var url = $(this).attr('action')+'?';
var first = false;
var second = false;
if($('input[name="first_name"]').val()){
url += 'first_name='+$('input[name="first_name"]').val();
first = true;
}
if($('input[name="last_name"]').val()){
if(first){
url += '&';
}
url += 'last_name='+$('input[name="last_name"]').val();
second = true;
}
if($('input[name="exam_name"]').val()){
if(second){
url += '&';
}
url += 'exam_name='+$('input[name="exam_name"]').val();
}
window.location.replace(url);
});
});
</script>
(i didnt ran this script yet, so let me know if u get any syntax error or somethign else.)
and finally change your results function to this,
public function results() {
$search_terms = array();
if(isset($_GET['first_name'])){
$search_terms['first_name'] = $this->input->get('first_name', TRUE);
}
if(isset($_GET['last_name'])){
$search_terms['last_name'] = $this->input->get('last_name', TRUE);
}
if(isset($_GET['exam_name'])){
$search_terms['exam_name'] = $this->input->get('exam_name', TRUE);
}
$data['title'] = "Search Results";
$data['exams'] = $this->search_model->get_results($search_terms);
$this->load->view('templates/header.php', $data);
$this->load->view('exams/index.php', $data);
$this->load->view('templates/footer.php');
}
You can try this:
$mode = array();
if(isset($_GET['first_name'])):
$mode[] = 'first_name='.$_GET['first_name'];
endif;
if(isset($_GET['last_name'])):
$mode[] = 'last_name='.$_GET['last_name'];
endif;
if(isset($_GET['exam_name'])):
$mode[] = 'exam_name='.$_GET['exam_name'];
endif;
//etc...
//Then reformulate link
if(!empty($mode)){
$link = '?' . implode('&',$mode);
}else{
$link = '';
}
redirect("form.php".$link);
just filter what you send...
foreach ($search_terms as $field => $value) {
if ($value <> ""){ //or the test you like to use...
$this->db->like("{$field}", $value);
}
}
