I wanna save values from an array into one field of my database. I've been using that code but nothing got saved.
$this->Form->input('Model.0.field1');
$this->Form->input('Model.0.field2');
$this->Form->input('Model.1.field1');
$this->Form->input('Model.1.field2');
Thanks.
I think you need to save data with json_encode() value.
// In your controller
public function test() {
if($this->request->is('post')) {
//If you want to insert in single row then you can use json_encode() and add to your colum.
$insert_data = json_encode($this->request->data);
$data = array();
// Load your model where you want save data
$this->loadModel('Test');
// set attribute name where you want to save
$data['Test']['value'] = $insert_data;
$this->Test->save($data);
//For viewing your data
$fetchedData = $this->Test->find('all');
foreach($fetchedData as $items) {
var_dump(json_decode($items['Test']['value']));
}
}
}
You can use implode() to generate comma separated data. If you want to use implode(), look at Inserting an array into a mysql database column

hello I have an edit form which displays the input fields.I am displaying the data from database in those fields so user can edit them. And also there is a button which ask to add new field. I am able to edit multiple fields but the problem is how can I create a new field in database if there is no existing id of the record.
Note: For the new field I am sending 0 id so that I can check in cakephp that it has a new field.
foreach ($exp as $k => $v) {
$dat[$k]["prp_id"] = $prpid;
$dat[$k]["exp_company"] = $v['company'];
$dat[$k]["position"] = $v['position'];
$dat[$k]["exp_id"] = $v['exp_id'];
}
$this->Experience->saveAll($dat, array('conditions' => array('exp_id' => $v['exp_id'])));
This is updating all the fields. Btw I am also not sure why its working correctly as I am here $v['exp_id'] sending only one value because its out of the loop but it is working perfectly meaning I can be able to multiple fields which I am not sure how. So In the end I have two problems. One is to create a new record if exp_id is 0 and second is why my this code works good for updating records.
Try this:
foreach ($exp as $k => $v) {
$dat[$k]["prp_id"] = $prpid;
$dat[$k]["exp_company"] = $v['company'];
$dat[$k]["position"] = $v['position'];
if ($v['exp_id'] != 0) {
$dat[$k]["exp_id"] = $v['exp_id'];
}
}
$this->Experience->saveAll($dat);
I am currently trying to set up an edit page where an order form is populated using json_decode to decode json information that was saved when the form was created. Because the form's size can change I have to create the correct number of inputs so that all the json data will have a place to be displayed. Fortunately as the inputs are numbered this should not be hard to do. Unfortunately I am not sure how to pick the last element of the json information that has been decoded. Currently I am using:
public function getEdit($id){
$order = Order::where('id', '=', $id);
if($order->count()) {
$order = $order->first();
$order->order_serialized = json_decode($order->order_serialized);
foreach($order->order_serialized as $key => $value){
$order->$key = $value;
}
return View::make('orders.edit')
->with('order', $order);
} else {
return App::abort(404);
}
}
to decode the information and it is working splendidly but I need to be able to pick up the last element to be able to find the total number of inputs and am not sure how I could do this without disturbing the foreach loop. Any and all help would be greatly appreciated!! Thank you so much!
You can use the count and toArray methods to find the last item.
$nItem = $order->count();
$aOrder = $order->toArray();
$aLastItem = $aOrder[$nItem-1];
Collections have a last() function to compliment the first() function.
This is probably a simple question but I'm having a hard time trying to create an object of the Model. I want to create a temporary variable that is the same as the model so I can update its internal values according to the data I am posting to the action.
My data is successfully posted to the action in the controller.
Currently what I am doing is grabbing all the items in the database and then assigning it the first item from the array. This way I can overwrite existing value, but if the table is empty it won't work.
I am using cakephp 2.x, I am new to this stuff which will explain why I couldn't figure this out.
Here is the code from the controller:
public function lcadd()
{
if ($this->request->is('post'))
{
// Create a new Local Clock object
$temp = $this->LocalClock->find('all'); // THIS IS THE PROBLEM AREA
$temp = $temp[0];
$temp['LocalClock']['name'] = $this->request->data['LocalClock']['Name'];
debug($temp); // THIS DEBUG ONLY DISPLAYS SOMETHING IF THE DATABASE TABLE IS NOT EMPTY
debug($this->request->data); // THE DATA COMING IN IS CORRECT AND I CAN ACCESS IT WITHOUT A PROBLEM
if($this->request->data['LocalClock']['Time Zone'] == 0 or $this->request->data['LocalClock']['Time Zone'] == -1)
{
//debug('Hello');
$temp['LocalClock']['auto_offset'] = 1;
}
else if($this->request->data['LocalClock']['Time Zone'] == 1)
{
$temp['LocalClock']['auto_offset'] = 0;
}
// Check the value posted from the DST
if($this->request->data['LocalClock']['DST Definition'] == -1 or $this->request->data['LocalClock']['DST Definition'] == 0)
{
$temp['LocalClock']['in_month'] = 0;
}
else if($this->request->data['LocalClock']['DST Definition'] == 2)
{
$temp['LocalClock']['in_month'] = $this->request->data['LocalClock']['InMonth'];
}
if ($this->LocalClock->save($temp))
{
$this->set('localClocks', $this->request->data);
$this->set('islcAddValid', true);
$this->set('lcaddValidationErrors', false);
}
}
}
I can't figure out how to make a simple object from the model. The model is LocalClock, and the controller is LocalClocksController.
The function above is in the LocalClocksController.
Thanks in advance.
A few things I noticed...
FIRST ISSUE:
// Create a new Local Clock object
$temp = $this->LocalClock->find('all'); // THIS IS THE PROBLEM AREA
$temp = $temp[0];
That's not creating a new Local Clock object. The first line returns an array (ie, not an object) containing ALL records in your Local Clock database table. Then, the second line says 'take the first row of the results, and store it in $temp'. So, now $temp holds an array (still NOT an object), containing the data of the first record in the LocalClock table.
You actually don't need an object, though, since the 'save' method that you call later on doesn't accept an object - it just accepts an array of data. You also don't need to get anything from the database in order to save a new record. So the code above should be replaced with:
$temp = array(); // Create an empty array. We will populate it as we go, with the data for the new record.
All the stuff in the middle of your method, up until you try to save the record, should work fine as it is.
SECOND ISSUE:
if ($this->LocalClock->save($temp))
Before calling 'save', you'll first need to call 'create' -
$this->LocalClock->create(); // prepare the Model to save a new record
if ($this->LocalClock->save($temp)) // This should now save a new record successfully.
Make sense? Let me know if you have any more questions.
Also, understanding how to retrieve, manipulate and save data from Models is very crucial to using CakePHP, and if you learn how to do it properly from the beginning, you'll save yourself countless hours of frustration in future. I'd recommend reading the following pages end-to-end:
http://book.cakephp.org/2.0/en/models/retrieving-your-data.html
http://book.cakephp.org/2.0/en/models/saving-your-data.html
I am new to code igniter data mapper. I have a table called user, and I am trying to retrieve data from the database table and show them to the user.
Here is what I have in the model:
$u=new User();
$results=$u->get_by_user_id($id);
//$results here will be set to huge bunch of none sense data( which also includes the row that I am looking for as well)
if ($u->exists())
{
foreach ($results->all as $row){
$data['user']['first_name']=($row->user_first); //this where I am stuck ..
$data['user']['last_name']=($row->user_last);//this is also where I am stuck..
}
I don't know how to treat results to get a required fields I am looking for and store them in the $data I am passing to the user to view.
Thanks!
When you call get_by_x() on the model, the fields will be populated with data and you can access them like this:
$u = new User();
$u->get_by_user_id($id);
if($u->exists())
{
// you can access the table columns as object fields
$data['user']['first'] = $u->first;
$data['user']['last'] = $u->last;
}
else
{
$data['error'] = 'No such user!';
}
Have a look at the documentation which is really helpful: see Get and Get By.
Also, DataMapper expects all tables to have an id column: see Table Naming Rules. If your column is named id you should then call $u->get_by_id($id) instead of $u->get_by_user_id($id).
If I have a person model with first_name and last_name, how do I create and display a full_name? I would like to display it at the top of my Edit and View views (i.e. "Edit Frank Luke") and other places. Simply dropping echoes to first_name and last_name isn't DRY.
I'm sorry if this is a very simple question, but nothing has yet worked.
Thank you,
Frank Luke
Edit for clarity: Okay, I have a function on the person model.
function full_name() {
return $this->Person->first_name . ' ' . $this->Person->last_name;
}
In the view, I call
echo $person['Person']['full_name']
This gives me a notice that I have an undefined index. What is the proper way to call the function from the view? Do I have to do it in the controller or elsewhere?
If what you are wanting is just to display a full name, and never need to do any database actions (comparisons, lookups), I think you should just concatenate your fields in the view.
This would be more aligned with the MVC design pattern. In your example you just want to view information in your database in a different way.
Since the action of concatenating is simple you probably don't save much code by placing it in a separate function. I think its easiest to do just in the view file.
If you want to do more fancy things ( ie Change the caps, return a link to the user ) I would recommend creating an element which you call with the Users data.
The arrays set by the save() method only return fields in the datbase, they do not call model functions. To properly use the function above (located in your model), you will need to add the following:
to the controller, in the $action method:
$this->set( 'fullname', $this->Person->full_name();
// must have $this-Person->id set, or redefine the method to include $person_id
in the view,
echo $fullname;
Basically, you need to use the controller to gather the data from the model, and assign it to the controller. It's the same process as you have before, where you assign the returned data from the find() call to the variable in the view, except youre getting the data from a different source.
There are multiple ways of doing this. One way is to use the afterFind-function in a model-class.
See: http://book.cakephp.org/view/681/afterFind.
BUT, this function does not handle nested data very well, instead, it doesn't handles it al all!
Therefore I use the afterfind-function in the app_model that walks through the resultset
function afterFind($results, $primary=false){
$name = isset($this->alias) ? $this->alias : $this->name;
// see if the model wants to attach attributes
if (method_exists($this, '_attachAttributes')){
// check if array is not multidimensional by checking the key 'id'
if (isset($results['id'])) {
$results = $this->_attachAttributes($results);
} else {
// we want each row to have an array of required attributes
for ($i = 0; $i < sizeof($results); $i++) {
// check if this is a model, or if it is an array of models
if (isset($results[$i][$name]) ){
// this is the model we want, see if it's a single or array
if (isset($results[$i][$name][0]) ){
// run on every model
for ($j = 0; $j < sizeof($results[$i][$name]); $j++) {
$results[$i][$name][$j] = $this->_attachAttributes($results[$i][$name][$j]);
}
} else {
$results[$i][$name] = $this->_attachAttributes($results[$i][$name]);
}
} else {
if (isset($results[$i]['id'])) {
$results[$i] = $this->_attachAttributes($results[$i]);
}
}
}
}
}
return $results;
}
And then I add a _attachAttributes-function in the model-class, for e.g. in your Person.php
function _attachAttributes($data) {
if (isset($data['first_name']) && isset($data['last_name'])) {
$data['full_name'] = sprintf("%s %s %s", $data['first_name'], $data['last_name']);
}
return $data;
}
This method can handle nested modelData, for e.g. Person hasMany Posts then this method can also attachAttributes inside the Post-model.
This method also keeps in mind that the linked models with other names than the className are fixed, because of the use of the alias and not only the name (which is the className).
You must use afterFind callback for it.
You would probably need to take the two fields that are returned from your database and concatenate them into one string variable that can then be displayed.

http://teknoid.wordpress.com/2008/09/29/dealing-with-calculated-fields-in-cakephps-find/
Read the first one to find out how to use the 'fields' key i.e. find( 'all', array( 'fields' => array( )) to pass a CONCAT to the CakePHP query builder.
The second link shows you how to merge the numeric indexes that get returned when you use custom fields back into the appropriate location in the returned results.
This should of course be placed in a model function and called from there.
