I wrote a function where I get array of marks that i need to post to my database..
My function stores it in a filed row like:
And I need to pull just one per column individually like:
Here is my api call..
public function generate(Map $seatMap)
{
$layout = $seatMap->getSeatLayout();
$seats = [];
$layoutArray = json_decode($layout, true);
$columns = range('A', 'Z');
foreach($layoutArray as $index => $result)
{
$columnLetter = $columns[$index];
$letters = str_split($result);
$letterIndex = 1;
foreach($letters as $letterIndex => $letter) {
switch($letter) {
case 'e':
$seats[] = $columnLetter . $letterIndex;
$letterIndex++;
}
}
}
foreach($seats as $seat => $result) {
$result = new Seat();
$result->setName(json_encode($seats));
$this->em->persist($result);
$this->em->flush();
}
}
Any suggestions?
I think that problem is in the part where I need to store it to database..
If I understand you correctly, your issue is here:
foreach($seats as $seat => $result) {
$result = new Seat();
$result->setName(json_encode($seats));
$this->em->persist($result);
$this->em->flush();
}
}
You're indeed creating new Seat instance for every seat, but in this line:
$result->setName(json_encode($seats));
you still assign all (encoded) seats to every instance of Seat. What you want is to assign only the seat from current loop iteration, which is represented by $result variable.
So try with:
$result->setName($result);
You do not need json_encode here too.
If your array is like you say it it then try this
foreach($seats as $seat) {
$result = new Seat();
$result->setName($seat);
$this->em->persist($result);
$this->em->flush();
}

I am currently working on a project (A music website) with PHP Codeigniter. I want to fetch top 15 songs by number of downloads. To my knowledge, I got all unique ID's out ranging from highest to least. But now, I want to use each of these unique ID's to fetch data from another table in the database.
I have tried using for loop; but it seems to only return one of the rows which happens to be the first and highest number of occurrence in the array. The code below echo's the ID's but how can I use each of those ID's to fetch data.
function top15(){
$this->db->select('musiccode');
$result=$this->db->get('downloads');
$query = $result->result_array();
$downloads = array();
if(!empty($query)) {
foreach($query as $row)
{
$musiccode[] = $row['musiccode'];
}
$mode = array_count_values($musiccode);
arsort($mode);
$i = 0;
foreach ($mode as $field => $number) {
$i++;
echo $field." occured ". $number." times <br>";
if ($i == 15) {
break;
}
}
}
}
for ($b=0; $b < count($field); $b++) {
$this->db->where(array('track_musiccode'=> $field));
$field = $this->db->get('tracks');
return $field->result_array();
}
The code above only produce one row for me. I expect to have more than one and according to the number of ID's in the array. Thanks in advance.
For a single column condition, you could use where_in() instead and drop the for loop :
$this->db->where_in('track_musiccode', $field);
$field = $this->db->get('tracks');
return $field->result_array();
Yes Finally i did it. Incase if anyone needs it. this works just fine
function top15(){
$this->db->where('d_month', date('m'));
$this->db->select('musiccode');
$result=$this->db->get('downloads');
$query = $result->result_array();
$downloads = array();
if(!empty($query)) {
foreach($query as $row){
$musiccode[] = $row['musiccode'];
}
$res='';
$count=array_count_values($musiccode);
arsort($count);
$keys=array_keys($count);
for ($i=0; $i < count($keys); $i++) {
$res[] .= "$keys[$i]";
}
$this->db->where_in('track_musiccode', $res);
return $this->db->get('tracks')->result_array();
}
}
And I got this too. If I wasn't going to count occurrences but just iterate the number of downloads which is far more better than counting in other not to over populate the database and make your website work slowly.
function top15(){
$tracks = '';
$this->db->group_by('counter');
$result=$this->db->get('downloads');
$query = $result->result_array();
$counter = '';
$fields = '';
if(!empty($query)) {
foreach($query as $row) {
$counter[] = $row['counter'];
}
rsort($counter);
for ($i=0; $i<=15; $i++) {
$this->db->where('downloads.counter', $counter[$i]);
$this->db->join('tracks', 'tracks.musicid = downloads.musicid');
$fields[] = $this->db->get('downloads')->row_array();
}
return $fields;
}
}
Enjoy...
I'am trying to fetch a session variable if the user is a guest. The variable is called "cart" and is set like this:
$product = new Collection((object) [
'product_id' => $request->pId,
'amount' => $request->amount,
'variations' => $variations
]);
Session::push('cart', $product);
Then I later fetch it:
if(Auth::check()){
$cartProducts = ShoppingCartItem::where('user_id', '=', Auth::user()->id)->get();
}else{
$cartProducts = Session::get('cart');
}
foreach($cartProducts as $product){
dd($product);
$totalAmount += $product->amount;
$totalPrice += (PriceHelper::getProductPrice($product->product->id, $product->amount));
}
The problem here is that dd($product) still outputs an array (the session variable array I assume) which means that for example $product->amount does not exist.
This is the output from dd($product):
You can either access the values using get():
foreach ($cartProducts as $product) {
$totalAmount += $product->get('amount');
$totalPrice += PriceHelper::getProductPrice($product->get('product_id'), $product->get('amount'));
}
or as an array:
foreach ($cartProducts as $product) {
$totalAmount += $product['amount'];
$totalPrice += PriceHelper::getProductPrice($product['product_id'], $product['amount']);
}
or you could use sum() on the collection instead of using foreach:
$cartProducts = collect(Session::get('cart'));
$totalAmount = $cartProducts->sum('amount');
$totalPrice = $cartProducts->sum(function ($product) {
return PriceHelper::getProductPrice($product['product_id'], $product['amount']);
});
Edit
For a quick fix if you need $product to be an object you could do something like:
$cartProducts = collect(Session::get('cart'))->map(function ($item) {
return (object)$item->toArray();
});
Hope this helps!
This question already has an answer here:
Cakephp add function if id exists edit else create
(1 answer)
Closed 6 years ago.
I want to update the record if the ID is exists in my database. If ID not exists create record. This is my code in my Controller add function
public function add () {
$googleCategory = $this->request->data;
foreach ($googleCategory as $key => $value) {
if(empty($value['category'])){
unset($value);
}
$this->AccountShopMeta->create();
$data['shop_id'] = $value['shop_id'];
$data['name'] = $value['category'];
$data['value'] = $value['url_key'];
$data['tag'] = '';
if($this->AccountShopMeta->save($data)){
$account_shop_meta = $this->AccountShopMeta->read();
$this->set($account_shop_meta);
$this->set('_serialize', array_keys($account_shop_meta));
}
}
}
if i understood what you are asking may be this will help you. Do not use Create. if id exist in given array ,updatation automatically will be done on that ID. Otherwise new row will be created.
public function add () {
$googleCategory = $this->request->data;
foreach ($googleCategory as $key => $value) {
if(empty($value['category'])){
unset($value);
}
if(!empty($value[id])){
$data['id']=$value[id];
}
$data['shop_id'] = $value['shop_id'];
$data['name'] = $value['category'];
$data['value'] = $value['url_key'];
$data['tag'] = '';
if($this->AccountShopMeta->save($data)){
$account_shop_meta = $this->AccountShopMeta->read();
$this->set($account_shop_meta);
$this->set('_serialize', array_keys($account_shop_meta));
}
}
}
I suppose if id not exists it comes as empty, in such case add following conditions within foreach and at least above save action:
foreach ($googleCategory as $key => $value) {
if(isset($value['id']) && !empty($value['id'])){
$this->AccountShopMeta->id = $value['id'];
// your remaining code within loop here
//
}
}
Do not forget to send data for id form your view(form) if exists..
In SilverStripe 3.1 I have a function that loops through an array and outputs its contents.
The output it gives me is:
Layout: John
Strategy: John
Management: Martin
In this example John has more than one job.
I would like to group the jobs if a person has more than one job.
This is my desired Output:
Layout and Strategy: John
Management: Martin
//$InfoFieldArray = array('Layout' => 'John', 'Strategy' => 'John', 'Management' => 'Martin');
public function createInfoFields($InfoFieldArray){
$Info = ArrayList::create();
foreach($InfoFieldArray as $key => $value ){
$fields = new ArrayData(array('FieldName' => $key, 'Value' => $value));
$Info->push($fields);
}
return $Info;
}
How do I alter my function to achieve my desired output?
One possible solution to that is by restructuring the data before adding it to the ArrayList.
public function createInfoFields($InfoFieldArray)
{
$info = array();
foreach ($InfoFieldArray as $job => $person)
{
if (!isset($info[$person]))
{
$info[$person] = array();
}
$info[$person][] = $job;
}
$result = ArrayList::create();
foreach ($info as $person => $jobs)
{
$fields = new ArrayData(array('FieldName' => implode(' and ', $jobs), 'Value' => $person));
$result->push($fields);
}
return $result;
}
What I have done is go over the array of jobs and the person assigned and flipped it the other way around, so I have an array of people with a list of jobs. This allows me to then just call implode in PHP, joining the various jobs by the word and.
There are some potential drawbacks, if there are two people named "John", they will be treated as one as I am using the name as the array key.
Also, if there are three jobs for a person, it will list it like "Layout and Strategy and Management". To avoid that, we need to modify the second foreach loop in my code to something like this:
foreach ($info as $person => $jobs)
{
$jobString = null;
if (count($jobs) > 1)
{
$jobString = implode(', ', array_slice($jobs, 0, -1)) . ' and ' . array_pop($jobs);
}
else
{
$jobString = $jobs[0];
}
$fields = new ArrayData(array('FieldName' => $jobString, 'Value' => $person));
$result->push($fields);
}
When there is more than 1 job for a person, we want to implode (glue together) the array pieces for the $jobs array however we don't want the last element at this point. Once array is glued together, we append with with and along with the last item.
I have just stumbled upon very strange behaviour. In my code I am saving new node with some fields. I must say this used to work perfectly well. However now it just stopped working. I use the devel module to print out the content of objects and variables and this is my code:
dsm($node);
node_save($node);
dsm($node);
The first dsm() function displays node object as I created it and as it is supposed to be. The second dsm() function displays entirely correct node object with nid populated, fields content, etc... However, none of the fields is saved in database although there is new record in {node} table. Also, node_save does not generate any kind of error.
Any idea what is happening here?
This is the function storing the node:
function manhattan_incident_save($data) {
if ($data['nid']) {
$node = node_load($data['nid']);
manhattan_compare_changes($node, $data);
}
else {
$node = new stdClass();
$node->type = 'incident';
node_object_prepare($node);
$node->title = manhattan_create_incident_id();
$node->language = LANGUAGE_NONE;
}
$node->field_incident_popis[$node->language][0]['value'] = $data['field_incident_popis'];
$node->field_incident_popis[$node->language][0]['safe_value'] = check_plain($data['field_incident_popis']);
$node->field_incident_agent[$node->language][0]['uid'] = isset($data['field_incident_agent'])?intval($data['field_incident_agent']):NULL;
$node->field_incident_zdroj[$node->language][0]['tid'] = intval($data['field_incident_zdroj']);
$node->og_group_ref[$node->language][0]['target_id'] = $data['field_incident_oblast']?intval($data['field_incident_oblast']):variable_get('manhattan_public_form_default_area_nid', NULL);
$node->field_incident_riesitel[$node->language][0]['uid'] = isset($data['field_incident_riesitel'])?intval($data['field_incident_riesitel']):NULL;
$node->field_incident_typ[$node->language][0]['tid'] = intval($data['field_incident_typ']);
$node->field_incident_doplnenie[$node->language][0]['nid'] = intval($data['field_incident_doplnenie']);
$node->field_incident_sposob_kontaktu[$node->language][0]['value'] = $data['field_incident_sposob_kontaktu'];
$node->field_incident_dovod_vzniku[$node->language][0]['tid'] = intval($data['field_incident_dovod_vzniku']);
if ($data['field_incident_suvisiaci_zaznam']) {
foreach ($data['field_incident_suvisiaci_zaznam'] as $file) {
$result = manhattan_save_files($file);
if ($result) {
$node->field_incident_suvisiaci_zaznam[$node->language][] = array('nid' => $result);
}
}
}
// now create/save the customer
if (function_exists('customer_customer_save')) {
$customer = $data;
$customer['nid'] = $data['field_incident_customer'];
$result = customer_customer_save($customer);
if ($result) {
watchdog('upvs', $result['message'], array(), WATCHDOG_NOTICE);
}
else {
watchdog('upvs', t('There was a problem with saving customer %nid'), array('%nid' => $data['nid']), WATCHDOG_ERROR);
}
}
// now we store nid of saved customer to the node object
$node->field_incident_customer[$node->language][0]['nid'] = $result['nid'];
dsm($node);
node_save($node);
dsm($node);
if ($data['nid']) {
watchdog('upvs', t('Incident number %title has been succesfully saved.'), array('%title' => $node->title), WATCHDOG_NOTICE);
}
else {
watchdog('upvs', t('Incident number %title has been succesfully created.'), array('%title' => $node->title), WATCHDOG_NOTICE);
}
return $node;
}
