I'm getting the following error message on all my pages in cakePHP:
The eventKey variable is required
Does anyone know what this is and how to get this fixed?
I have no clue where it comes from.
Thanks!
Please check for an empty Construct { } in your models
It can be naming function too.
When function name is similar/like model name, my example:
model ProfileFriend,
function: function profileFriend(){...}
use: $this->ProfileFriend->profileFriend();
Yeah I know, my function name looks weird when I write model name before function name, but when my code look like this:
$model = $this->modelClass;
// ....
$is_friend = $this->$model->profileFriend();
// ...
... then my function name doesn't looks so weird.

As I am including elements/header.ctp file in another main.ctp file..
<?php echo $this->element('header'); ?>
I have included header in main.ctp it is displaying quite good. but when I am writing the query in ElementsController in is throwing an error undefined varible..
Below code for Elements Controller header() is the included file function.
public function header()
{
$this->set('marquee',$this->Newsmaster->find('all',array('order'=>array('Newsmaster.priority DESC'),'limit' =>20)));
$userid = $this->Session->read('user');
}
can anyone help me in solving this please... thank You
Elements Controller is not needed to set "marquee" varaible , you need to code in your usual controller for eg. for pages/index you will need to set variable in PagesController's index function not in under ElementsController
I have this error:
Notice (8): Undefined variable: informations [APP/View/Information/index.ctp, line 2]
I have this function in my controller
public function index($slug){
$this->layout = 'sbhealth';
$this->loadModel('Menu');
$informations = $this->Menu->findBySlug($slug);
if($informations){
$this->set('index', $informations);
}else{
return $informations = "not find";
}
}
I need to pass datas to my view "index.ctp" index.ctp will then find the ID in my array to pass it to an Element. but the View doesn't recognize "$informations"
This probably doesn't constitute something that should be on StackOverflow, since it's specified in great detail in the book, but...
// in your controller
$this->set('informations', $informations);
The first item is the name of the variable that will be available in the view.
The second item is the value you want to put in that variable.
In my CakePHP application, I have a model like this:
class Duck extends AppModel {
var $name = 'Duck';
function get_table_name() {
$tbl_name = //compute default table name for this model
}
}
I would like to write the function get_table_name() that outputs the default table name for the model. For the example above, it should output ducks.
EDIT:
Several people have pointed out the use of $this->table.
I did small testing and found out the following:
In the question as I have put above, $this->table indeed contains the table name.
However, actually, my code looked more like this:
class Duck extends Bird {
var $name = 'Duck';
function get_table_name(){
$tbl_name = //comput default table name for this model
}
}
class Bird extends AppModel {
}
In this case $this->table is empty string.
I went with this approach because I wanted to share some code between two of my models. Looks like this is not a good way to share code between models which need some common functionality.
You're looking for the Inflector class.
Inflector::tableize($this->name)
(tableize calls two Inflector methods to generate the table name: underscore() and pluralize())
Edit:
According to the source code, $this->table should contain the name of the table that CakePHP will use for the model, but in my experience this isn't always set. I'm not sure why.
To get the name of the table that the model is currently using, you can use: $this->table. If you don't manually change the model's table conventions, this may be the most useful in the case of CakePHP ever changing its conventions to use table names using something other than Inflector.
CakePHP's Inflector
function get_table_name() {
$tbl_name = Inflector::pluralize($this->name);
}
OR the tableize method
function get_table_name() {
$tbl_name = Inflector::tableize($this->name);
}
Edit
This also addresses the apparent "ghost" issue with $this->table in the Model.
Digging around in the __construct for Model I discovered two things:
Cake uses Inflector::tableize() to get the table name. This alone is enough to warrant using tableize over pluralize. You'll get consistent results.
$this->table is not set by the Model::__construct() unless $this->useTable === false AND $this->table === false.
It appears that if you know you haven't set $this->useTable to false you should be able to use this over $this->table. Admittedly though I only briefly scanned the source and I haven't really dug deep enough to say why $this->table isn't working sometimes.
To get the full table name for a model you have to take the table prefix into account.
$table = empty($this->table) ? Inflector::tableize($this->name) : $this->table;
$fullTableName = $this->tablePrefix . $table;
I used to use inflector to get the table name from model's name
$tableName = Inflector::pluralize(Inflector::underscore($model));
but this is not really universal, using useTable looks better, by default it will contain table's name by convention, and if you have a table that does not match the conventions, then you should manually specify it by useTable. So, in both cases the result will be correct
$this->User->useTable
I follow in book.cake and I don't know I should send something to the parameters.
function beforeSave() {
if (!empty($this->data['Article']['create_dt']) && !empty($this->data['Article']['modified_dt'])) {
$this->data['Article']['create_dt'] = $this->dateFormatBeforeSave($this->data['Article']['create_dt']);
$this->data['Article']['modified_dt'] = $this->dateFormatBeforeSave($this->data['Article']['modified_dt']);
}
return true;
}
I try to search example but don't found.
I need many example
somebody can help me to find big resource
thank for suggest
beforeSave is called automatically by Cake before it saves data. In it, you can do whatever you want to do before each save. Typically this means altering $this->data, which is the data that is about to be saved.
The method is passed one parameter: an array of the form array('validate' => true/false, ('fieldList' => array(...)). This corresponds to the two extra parameters you can supply to save():
$this->Model->save($this->data, false, array('foo', 'bar'));
In this case the array would look like
array('validate' => false, 'fieldList' => array('foo', 'bar')).
You can accept this array by specifying an argument:
public function beforeSave($options) { ... }
$options will look like described above. You can use this information any way you want.
If you don't return true from beforeSave, the save operation will be canceled altogether.
That's all.
try using created and modified magic fields with datetime type in table cake would automatically handle them
i want to mention, that beforeSave() should be used carefully, because it is used on every time when data is saved with this model.
if you forget that it is used, you will get unexpected results.
Happens to me several times... ;)
I am using cakephp. I have a form with an element array.
For ex:-
<textarea name="data[User][0][description]>
<textarea name="data[User][1][description]>
From the controller, I need to invalidate (manually) the array field if it is empty and need to show errors to the respective field.
What is the correct syntax for invalidating the field if it an element array ?
I know, the following will work for single element . How it will be for an element array ?
$this->User->invalidate("description");
Unfortunately you cannot invalidate the field with that function.
But what invalidate() does?
function invalidate($field, $value = true) {
if (!is_array($this->validationErrors)) {
$this->validationErrors = array();
}
$this->validationErrors[$field] = $value;
}
It just set validationErrors of the model.
So, you can do following in your Controller (but I also appeal you to move that validation in the Model):
$this->User->validationErrors[1]['description'] = 'Your error message';
The following code will invalidate the second description in the list.
HTH
You can type in view:
<?php
echo $this->Form->error("User.1.description");
?>
Thanks Nik,
your answer helped me, but halfway, because my problem was with a compound field by other subfields.
account_number {
bank_code,
bank_office,
check_digit,
account
}
In this case if we need put in validation error in one subfield, this is the solution:
$this->Model->validationErrors['account_number']['bank_code'][0] = 'Your message error';
I hope this help someone.
Regards.
I had similar problem, since it was for admin panel I showed error message on the first level of field i.e. for this portion only.
If you are validation on controller, just create an array of error with field name and error message, set it in controller and display message if in_array($field, $withErrorArray) in view.
