I'm using containable to pull associated records into the view action and am getting an error message when looping through results.
Also, I'm using a 'sluggable' behaviour, so the find operation has a condition to search by this variable.
When I debug the find variable in the view, I do see the correct records. But when I try and loop through them in the view I get the 'Notice (8): Undefined index: error.' Ideally I liked to understand how to trouble shoot this error since it happens occasionally.
The model setup is:
tournaments have many tournamentDetails
tournamentDetails have many updates
The records I'm trying to display are:
tournament->tournamentDetails->updates
The tournament controller looks like this:
$tournament = $this->Tournament->find('first', array(
'conditions' => array( 'slug' => $slug),
'contain' => array(
'TournamentDetail' => array(
'Update' => array('order' => 'Update.id DESC'),
))));
The tournament view action looks like this:
<?php foreach ($tournament ['Update'] as $update): ?>
<h3>Update: <?php echo $update ['Update']['date']; ?></h3>
<h4><?php echo $update['Update']['title']; ?></h4>
<p><?php echo $update ['Update']['body']; ?></p>
<hr/>
<?php endforeach; ?>
The 'update' data in the view when in debug looks like:
[Update] => Array
(
[0] => Array
(
[id] => 2
[title] => Indoor Challenge
[date] => 2010-03-19
[body] => Congratulations 2010 Champion
[tournament_detail_id] => 4
[homeStatus] => no
)
[1] => Array
(
[id] => 1
[title] => first round matches start today
[date] => 2010-03-19
[body] => this tournament's first round matches start today.
[tournament_detail_id] => 4
[homeStatus] => no
)
Is there something really obvious that I'm overlooking when looping through the 'updates' ?
Thanks, Paul

Thanks everyone for the input. After taking a few steps back it occured to me what was happening with the 'undefined index' and comments about how to loop.
The problem was that the foreach loop wasn't nested, it only looped on the first level of association. The forearch loop deal with 'tournaments' which have many 'tournamentDetails'.
The loop needed to go one level deeper to 'tournamentDetails that have many 'updates'.
Here's the code that resolved this in the view.
<?php foreach ($tournament['TournamentDetail'] as $tournamentDetail): ?>
<?php foreach ($tournamentDetail ['Update'] as $update): ?>
<h3>Update: <?php echo $update['date']; ?></h3>
<h4><?php echo $update['title']; ?></h4>
<p><?php echo $update['body']; ?></p>
<hr/>
<?php endforeach; ?>
<?php endforeach; ?>
If others are looking to understand how to use the containable behavior with more than one level of association, just remember that you may have to have nested foreach loops in the view to display the results you're after.
Cheers, Paul
Paul,
given that the other things are right, could it be that you are mixing singular, plural, uppercase and lowercase? In particular the update/updates in various combinations.
Edit 0:
Quick shot?:
There simply is no such index defined, notice that you are working with an array consisting of arrays. It seems you have to use another loop nested in the first.
Edit 1:
Unfortunately, I can only provide quite generic help, as I do not sit infront of your code.
From your post and comments, I would guess that some variable names got mixed up. Just going over the whole dataflow normally does it. What is the exact variable name in the controller which delivers the correct data? If there is one, is it properly set from the controller to the view? Does the view address it correctly.
You are thinking great, this is what I did the last week, but I am quite sure that should do it. Clean out all the view code which currently makes use of any variables from the controller, proceed as described above keeping the dataflow in mind (but do not spend more than one hour on this).
If it does not work:
Something is foobared. Before you spend another week in despair, I would
try it without the containable behavior, see if it works
try to set up exactly the
same scenario in a completely new
CakePHP environment (in your case
1.2.5), see if it works
If you achieve your goals, try to see what went wrong in the original (often a face slapping moment).
If not:
try to see if there is a known bug
consider upgrading (or try to achieve your goals in 1.3.7 first)
Good luck, Benjamin
I think i understand you problem and please Try looping in this way
<?php foreach ($tournament ['Update'] as $update): ?>
<h3>Update: <?php echo $update['date']; ?></h3>
<h4><?php echo $update['title']; ?></h4>
<p><?php echo $update['body']; ?></p>
<hr/>
<?php endforeach; ?>
RSK's answer should be right, so since it's still not working you're probably not giving all the information needed. What does this output:
debug($tournament); ?
This all assumes your debug information is debug( $tournament ) and not debug( $update )
/* your old code */
<?php foreach ($tournament ['Update'] as $update): ?>
<h3>Update: <?php echo $update ['Update']['date']; ?></h3>
<h4><?php echo $update['Update']['title']; ?></h4>
<p><?php echo $update ['Update']['body']; ?></p>
<hr/>
<?php endforeach; ?>
If the debug value you provided was a debug of the $tournament variable then the first part of your loop simply assigns the numerically keyed arrays inside of the tournaments variable to the $update value.
So, when you send $tournament[ 'Update' ] through the loop you are getting a structure in the $update array like the following.
array(
[id] => 2
[title] => Indoor Challenge
[date] => 2010-03-19
[body] => Congratulations 2010 Champion
[tournament_detail_id] => 4
[homeStatus] => no
)
But in your loop you are trying to access the keyed values as if they exist under an additional layer keyed with 'Update'. That key does not exist in your interior array.
So if my assumption is right - your loop should look like:
/* your old code with edits removing the additional interior Update key */
<?php foreach ($tournament ['Update'] as $update): ?>
<h3>Update: <?php echo $update['date']; ?></h3>
<h4><?php echo $update['title']; ?></h4>
<p><?php echo $update['body']; ?></p>
<hr/>
<?php endforeach; ?>
There also seemed to be some spacing in your brackets in the original code - I don't know if this is an issue or not but it looked odd to me.

I am using CakePHP 2.4. I have a blog where I can add and edit posts. When I implemented my edit.ctp, I recognized, that I have the same code in the view add.ctp:
<?php
echo $this->Form->create();
echo $this->Form->input('headline');
echo $this->Form->input('text', array('type' => 'textarea');
echo $this->Form->end('Save');
?>
(simplified code)
Regarding CakePHP´s recommendation, I want to keep my code DRY. What is the best way to define the form only one time and use it in both views?
Create a view in the folder Element with the form code
// app/View/Elements/postForm.ctp
<?php
echo $this->Form->create();
echo $this->Form->input('headline');
echo $this->Form->input('text', array('type' => 'textarea');
echo $this->Form->end('Save');
?>
Then include it in your desired views
echo $this->element('postForm');
I am new to cakephp framework and i am using cakephp3.0 now i used baking concept instead of using scaffolding. After baking it automatically generated all pages based on my tables in database and it generated code in models,controllers and views.Now my question is "if it is possible to change the code in views to change field types (from text box to radio button) according to my requirements."
Please help me.
Thanks in advance
Yes, after you bake your project you can change the fields types. Navigate to the folder where all your views are located, for example: app\View\MyViewName. Baking is a great tool to get something up and running fast. If you have a fairly structured website mostly used for data entry this is a great tool. I used it for simple data entry websites and it has saved me so much typing! Just add some data validation/constraints in the model and you're good to go!
A freshly baked view will look a little something like this:
<div class="MyForm Form">
<?php echo $this->Form->create('MyForm'); ?>
<fieldset>
<legend><?php echo __('Add My Form'); ?></legend>
<?php
echo $this->Form->input('field1');
echo $this->Form->input('field2');
?>
</fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>
<div class="actions">
<h3><?php echo __('Actions'); ?></h3>
<ul>
<li><?php echo $this->Html->link(__('List My Forms'), array('action' => 'index')); ?></li>
</ul>
</div>
Change the input methods to look something like this:
$options = array('Y' => 'Yes', 'N' => 'No');
echo $this->Form->radio('myFields', $options);
created a view function and any time i click the link to view a template, the url at the top of the page is correct but it spits out the same list of fields in the database.
the fields are
accounts - id, company name, abn
template - id, name, description, account_id
field - id, name, field type, template_id
function view(){
$accounts=$this->User->AccountsUser->find('list',
array('fields'=>array('id', 'account_id'),
'conditions' =>array('user_id' =>
$this->Auth->user('id'))));
$templates=$this->Template->find('first',
array('conditions' => array(
'Template.account_id' => $accounts)));
$fields=$this->Field->find('all',
array('conditions' => array(
'Field.template_id' => Set::extract('/Template/id', $templates))));
$this->set('template', $templates);
$this->set('account', $accounts);
$this->set('field', $fields);
}
here is the view
<div class = "conlinks">
</br></br></br></br></br><h2>Here is your template fields</h2></br>
<?php foreach($field as $fields): ?>
<tr>
<td align='center'><?php echo $fields['Field']['name']; ?>
</tr></br>
<?php endforeach; ?>
</div>
so the problem is its grabbing the exact same list of fields, not the correct template_id when it prints out the fields
You should be able to debug this for yourself. Just narrow the bug down step by step.
For starters, in your view function, do a print_r on the following variables, and make sure each one contains a logical result:
$accounts
$templates
$fields
If you find unexpected results there, I'd be looking at the parameters you pass into each of your finds, and making sure they're OK. You're passing in $accounts as an array to your find condition - make sure it matches the format that cake expects. Do the same for Set::extract('/Template/id', $templates).
Also look at the SQL that Cake is producing.
If you're not already using it, I'd highly recommend installing Cake's Debug Kit Toolbar - https://github.com/cakephp/debug_kit/ because it makes debugging variables and SQL much easier.
If you do the above steps and can't solve your problem, you should at least be able to narrow it down to a line or two of code. Update your answer to show what line or two is causing the problem, and include print_r's of some of the variables you're working with. That should help others on StackOverflow to give you a specific answer.
Hope that helps!
the issue was I wasn't getting the parameters when click the link
function view($name){
$fields = $this->Template->Field->find('list',array(
'fields'=> array('name'),
'conditions' => array(
'template_id'=> $name)));
$this->set('field', $fields);
}
and the view
<div class = "conlinks">
</br><h2>Here is your template fields</h2>
<?php foreach($field as $name): ?>
<tr>
<td align='center'>
<?php echo $name; ?>
</tr></br>
<?php endforeach; ?>
</br>
<?php
echo $this->Html->link('Back', '/templates/view', array('class' => 'button'));?>
</div>
On my Magento product page; when a product has multiple values for one custom attribute; instead of displaying the values it displays the text "array". It works fine with one value.
Thanks,
-Sam
You can do something like:
<?php
foreach($_product->getMetal() as $name => $value): ?>
<?php echo $name;?> = <?php echo $value;?>
<?php
endforeach; ?>
Magento takes advantage of PHP's magic getter/setter functionality (http://www.php.net/manual/en/language.oop5.overloading.php#object.get).
You can do a vardump($_product) to see the available attributes (they are stored in the _data array in the product). Then to retrieve one of them, you just remove the underscores and change the first letter of each word to uppercase.
EDIT:
If the above code doesn't output values, you can do this (which will tell you how to get to the value):
<?php
foreach($_product->getMetal() as $attribute): ?>
<?php var_dump($attribute); ?>
<?php
endforeach; ?>
I found this on Magento forums and it seems to work:
` getData('attribute_name')): ?>
getResource()->getAttribute('attribute_name')->getFrontend()->getValue($_product)) ?>
`
I have a problem with the Form Helper that returned $this->data keeps being empty. In my Forms before there was no problems and I cant figure out what's different here.
For this Form there's not a model containing the data, its just user input for doing a search.
This is my View:
<?php
echo $this->Form->create();
echo $this->Form->input('Postleitzahl');
$options=array('10'=>10,'20'=>20);
echo $this->Form->input('Entfernung',array('type'=> 'select' , 'options'=>array(($options))));
echo $this->Form->end('Suchen');
?>
<?php
echo $this->Form->create(null, array('type' => 'post')); # not sure if that's needed
echo $this->Form->input('Search.Postleitzahl');
$options=array('10'=>10,'20'=>20);
echo $this->Form->input('Search.Entfernung',array('options'=> $options)); # seems shorter and should work
echo $this->Form->end('Suchen');
?>
The above should result into a $this->data array containing something similar to this:
['Search']
['Postleitzahl']: 102929
['Enfernung']: 'foobar'
Just don't double array your array:
'options'=>$options
Not necessarily related to Cake, but the answer to the problem when I had it: if you're including a file upload in your POST, double-check that the file you're uploading isn't larger than the limit specified in your php.ini file.
