Re: Implementing a search functionality

I didn't search there. I used another little know search engine called Joogle (or something like that): http://cakedc.com/downloads/view/cakephp_search_plugin

I looked in the book on cakephp.org and didn't find the search behavior.  Do you mean some other book?  Did I miss what you're describing?

The answer (again) is in the error message. 'set' is a controller function and you are using it in a behaviour. set 'sets' a variable in the controller and passes it to the view. Here's the chain of events:

- user clicks a link or submits a form to a specified url
- that url is routed to a controller action (/controller/action/[parameters])
- the controller action does the stuff you tell it to
- this usually means calling some model functions, in your case the search method of the Provider model
- the model can use a behaviour method, in your case the search method of the Searchable behaviour (when a behaviour is attached to a model its methods are available as if they were native to the model)
- the model/behaviour performs database activity/business logic and returns variables to the calling controller function (note: 'return')
- the controller function receives those variables and 'sets' them ready for the view
- the controller then renders the view (generally of the same name as the controller action)
- the view renders html and can refer to the variables set and passed by the controller

Your code is not doing this.

Yves - can I recommend that you read the Cookbook? Amongst other things there is a really good Searchable behaviour out there that will do what you need.

Fatal error: Call to undefined method SearchableBehavior::set() in D:\Inetpub\wwwroot-clinical\pythia-admit-lookup\app\models\behaviors\searchable.php on line 4

I find this confusing.  I'm already setting the last_name in my view... so shouldn't it be grabbing that info?

Jeremy, thanks for your help.  I'll take the time to go through the blog tutorial at the moment.  I was kind of forced into this development process with little prep work or understanding of what's going on (the same would be to have you write a project in APL :-] ).

I'll get back to this thread after learning more about how Cake works and what it is capable of.

Your controller function sets variables and passes them to a view of the same name as the function. In your case, your function is called search_admit_lookup, so it will try to render a view called search_admit_lookup. That view will contain the logic to present whatever variables are set in the function and passed to the view. You can use whatever html you want in the view.

Gonna look into that now.

Yup - looks better now, and you are right you are setting the provider variable - I was looking at the wrong function. ^^

So are you all in the clear now?

OK - but you still haven't applied all of the changes I outlined.

This line in your controller:
  1.     function view_admit_lookup() {
  2.         $this->set('provider', $this->paginate());

...is setting a variable called $provider with a value. That will be available in the view (view_admit_lookup) as $providers.

In your view you are looping through a variable called $Providers.

 <?php foreach ($Providers as $i => $prov): ?>

$providers does not equal $Providers.

I'd change the controller to:

  1.     function view_admit_lookup() {
  2.         $this->set('providers', $this->paginate());

... and the view to

 <?php foreach ($providers as $i => $prov): ?>

Also see my comment about your form name in the view (and the use of $form). To save you the tiresome task of actually reading anything and carrying out the instructions, let me correct it for you:

  1.     echo $this->Form->create("Provider", array('action' => 'search'));
  2.     echo $this->Form->input("doc_last_name", array('label' => 'Doctor Last Name'));
  3.     echo $this->Form->submit('Search');
  4.     echo $this->Form->end();

Also, the form is specifying that it posts to an action 'search' - does this exist in your providers controller? I can't see it.

Why. Not. Read. My. Post? And the guide? With the link I sent you?

From this tree I can tell you that the model file should be lower case and that view is not named correctly. Lower case, with underscores, to match the controller function name (as I mention in my post(s)).

Once you have read the answers to your questions, applied the advice and adhered to conventions, please come back with any other errors.

Your conventions are all over the place. Its best to stick to them.

Did you change the code inside the controller as suggested in my first post?

  1. class ProvidersController extends AppController {
  2.     var $name = 'Providers';

The filename is view_admit_lookup, yet the controller function is viewAdmitLookup - they should match. Change the function name to view_admit_lookup

In the view, you have this:

echo $form->create("Providers", array('action' => 'search'));

It'll create a form that tries to find the Providers model, not the Provider model. Change it to:

echo $form->create("Provider", array('action' => 'search'));

Change Providers to Provider throughout the view code.

In your controller function you have $this->set('providers'... which sends a variable $providers into the view, yet in the view you are iterating through a variable called $Providers. Change the variable in the view to $providers.

Your are using $form-> when you should be using $this->Form (that's the syntax for helpers in general, so $this->Html etc).

See this section of the book on conventions:


You can deviate from them with additional work, but it is not worth the effort else you'll run into issues like this.

Now, I don't have Providers, I have Provider (singular only), so where is it getting the plural from?

my apologies, I saw where you said you wanted to make the tutorial simpler and i assumed that you already knew how to make calls etc. 

The tutorial is using a search behavior (which probably does the calls - i haven't looked to verify)

but to answer your question from above, I would recommend doing the tutorial OUTSIDE of your current project just to familiarize yourself with what it is asking you to do. 

Once you get that up and running you would have a much better understanding of what direction you would rather go in as a developer. 

so...yes...follow all steps in the tut. 

Now, if you are going away from the tutorial, you can just the data that comes back in the $this->data collection from your search box in the view and use that model call I used above.  If you dont understand this last bit, it is best you try the tutorial out first with a fresh install etc...so as not to disrupt your project or in the very least back it up.
