In the index action of my UsersController I want to pass strings and arrays to view, so that my View is render correctly. I don't know what am I doing wrong but my view file is not getting one of my array to view.
$users = $this->User->getUsers();
//Setting all variable that are present in layout
$this->set('title_for_layout','Users - Admin');
$page_headings = array("text" => "Users", "clss" => "icon-head");
$this->set('page_heading', $page_headings);
//Ends here
//This is actually going to action view file
$this->set(compact('users'));
My View file Code is like this
<div><?php echo $page_heading[0]['text']; ?></div>
<?php foreach($users as $user){ ?>
I am able to get $users variable here but noting getting $page_heading.
I am getting this error Undefined variable: page_heading.
I have tried everything like these:
$this->set($page_headings);
$this->set(compact('page_headings');
and yes I have change my variable name in view file also to page_headings after doing above code. I am not able to get it working. Can Please anybody help.
Thanks in advance.
This was happened because I was editing my live server file directly from filezilla's edit option and when I was saving it after editing file, it was somehow becoming the one line code and because of the comment tag all code that I had edited became comments.
I rectified this problem when i took fresh copy from server.
So what I learned today: After say working about half an hour on file, take updated file from server if you editing from filezilla because you don't know how it gonna save the file.
Thanks ndm for your help.

I'm new in CakePhp but experienced in CodeIgniter. I created a controller in "WelcomeController.php" in controller directory and run the page. I got two errors
1. Error: The view for WelcomeController::index() was not found.
2. Error: Confirm you have created the file: C:\xampp\htdocs\myc\app\View\Welcome\index.ctp.
My question
Why I am getting this error even though I have supplied index() function?
In codeigniter we may not create a directory for a view. I don't want to create a directory "Welcome" in view. I there any provision provided?
In Cakephp you have to create view for function or here it called action. In your case, Create index.ctp on App->View->Welcome folder. This Getting Start
will give you a basic idea.
1) You're getting that error because your missing the view, not the controller function. To fix, do what the error suggested:
Confirm you have created the file: C:\xampp\htdocs\myc\app\View\Welcome\index.ctp.
2) "I don't want to create a directory "Welcome" in view. I there any provision provided?".
Not really... I mean, no if you want that action to have a correspondent view to put the content. Otherwise you can use $this->autoRender = false to not show anything... But that'll mean the url localhost/welcomes/index will be blank.
I recommend you read the basics as Fazal said. I know every framework can give us "quirks" and we end up expecting every other framework to work the same way we are used to, but try to adapt to the cake-way.
Btw, should be "WelcomesController", according to cake conventions
Be sure that you have all the files and directories necessary for the modal, controller and view to link up correctly i.e.: Create the folder called welcome(s) in your views directory with an index.ctp file. This should get rid of that error.

I dont understand why I am not able to update a field on the database based on the following code:
$this->User->id = 1;
$this->User->saveField('image','img/default_pic.png');
Basically, I want to change the current image in the Db with a new one.
The code above just clears the value that is currently in the image field, but does not add anything.
As an example, this is what happens:
id username image
=============================
1 admin mypic.jpg
2 john johnPic.jpg
After the code above is executed I get the following result
id username image
=============================
1 admin
2 john johnPic.jpg
I am confused at what is actually happening
SOLVED!
I decided to go back and check on my user.php model class and realized that I had attempted to use MeioUpload before and gave up, but I never removed the var actsAs entry.
As soon as I commented it out, I am now able to upload pictures.
For anyone else that might come across this issue, beforeSave might also caused these kind of problems, according to the following blog: http://blog.phplabs.net/2011/11/cakephp-savefield-not-working.html
Thanks,
What does the sql log say is happening?
My guess is you are actually doing something like
$this->User->saveField('image', $variable)
and $variable is either misspelled or is empty.
For some reason my cakephp application is not showing any of the queries made to the database. It prints the table fine, but there are not records. What could cause this?
Check to make sure you are pulling the records correctly.
$models = $this->Model->find('all');
// or
$this->Model->recursive = 0;
$this->set('models', $this->paginate());
Then when you add them in the view, be sure you are looping through them correctly:
foreach ($models as $model) {
echo $model['Model']['field_name'];
}
UPDATE
To show the SQL statements, be sure you have the following set in core.php
Configure::write('debug', 2);
Also, in the Layout, besure you have this included someone between the <body> and </body> tags:
<?php echo $this->element('sql_dump'); ?>
I assume that you are getting an empty table with just the "Nr","Query","Error", etc. column headers?
You are getting the empty table because you have "Configure::write('debug',0);" set somewhere before you have "Configure::write('debug',2);" set. Find the first instance of it and delete it or change it to "2".
I know that you have long since fixed this problem but hopefully it helps somebody else in the future.
The CakePHP debug kit can help you. After you install it, you will notice a small (pie-chart) icon on the top right of your CakePHP pages. Clicking on that will allow you to see various useful information, and most importantly for this issue, all the SQL queries that occurred in the back-end upon the page loading.
I faced a similar problem in cakephp. I found that debug($variable) has limitation to the content size. Since you are fetching huge sized content from database, it is not able to print. Try doing print_r($variable) instead. To format it properly, you can do like this
echo "<pre>".print_r($variable)."</pre>";
I am using cake php now. I have two file example1.ctp and example2.ctp. I want to include example2.ctp in example1.ctp just like how we add php page using "include". I am new to this please suggest me how to do it.
According to me , You have to create Elements..
CakePHP can help you repeat parts of your website that need to be reused. These reusable parts are called Elements.
<?php echo $this->element('ur elements ctp file name'); ?>
I am using cakePHP v1.26.
In the default.ctp file,
I got a single of this code in it:
$session->flash();
I came a corss a web site in which the author suggested using this instead:
if($session->check('Message.flash')){
$session->flash();
}
I do not understand what this line of code is doing:
if($session->check('Message.flash')){...}
what is "Message.flash" in this case?
Is "Message.flash" a custom variable or
a built-in varibale which has been predefined in cakePHP?
Message.flash is the session variable name. It will be defined by cakephp, when you use $this->Session->setFlash('Your message'); from your controller.
if($session->check('Message.flash')){...} checks, if session Message.flash, which contains the flash message, exists.
Note also that contrary to the current manual description, $session->flash() does not echo the result, it just returns it, so you will need to have
echo $session->flash();
in your view.
For latest cakephp version
if(!($this->Session->check('Message.flash')));
// your code
In view section for show messages.
$this->Session->flash();
