For reference, please visit this page here. When trying to get a view display on one particular model, I am getting an undefined index error. Specifically, any data from my Coupon model. Here is my controller code:
public function seafood() {
$this->paginate['Restaurant']=array(
'limit'=>9,
'order' => 'RAND()',
'contain'=>array(
'User'=>array(
'id', 'user_name'),
'Coupon'=>array(
'id','description','expires','end_date','promo_code','restaurant_id')
),
'conditions'=>array(
'Restaurant.active'=>1,
'Restaurant.seafood'=>'Seafood'
)
);
$data = $this->paginate('Restaurant');
$this->set('seafood', $data);
when I debug($seafood) in my view, all data for Coupon shows, so I know it is correctly pulling data and associating it with my Restaurant model. However, when I create a foreach loop with my $seafood array, I get nothing but undefined index errors for anything Coupon-related. What's weird is that I also have my controller pulling from the User model and anything I call up from that model in the view gets rendered. Here is my view code:
<?php foreach ($seafood as $res) { ?>
.....irrelevant code.....
<p><?php if($res['Coupon']['description'] !=''){
echo $this->Text->truncate($res['Coupon']['description'], 200, array('ending'=>'...', 'exact'=>false) );
}
else echo 'Sorry, a description of this restaurant\'s promotion is not available. <br><br><br>';
?><em> (read more -->)</em></p>
<br />
<div>
<span style="margin-left:36px;">Promo Code: <span style="font-style:bold; color:#FF0000;"><?php echo $res['User']['user_name']; ?></span></span>
<span style="margin-left:24px;">Print</span>
<?php } ?>
......more irrelevant code.....
I have tried removing the containable behavior from the array but the results are the same. I should point out that when the debug array prints, it goes in order: Restaurant, User, Coupon. Is cake somehow losing the Coupon array because it is 3rd? Or is my view code just screwy?
Looks like Restaurant hasMany Coupon so Coupon is an indexed array. You'll need a nested for loop.
foreach ($seafood as $res) {
//irrelevant
foreach ($res['Coupon'] as $coupon) {
if($coupon['description'] !=''){
//do stuff
}
}
}

My Problem I can't get my dynamic checkboxes to save properly in from my edit.blade, they only work if the values are 1, if an unchecked checkbox is submitted via hidden field it will overwrite the next set of checkbox checked values.
My Code
I have a crud resource that takes orders, the form in the create.blade itself has a bunch of dynamic fields that add a new product to the order via 'add-new' button that clones the product fields.
Part of that form is a bunch of days checkboxes that work fine and are stored correcly.
Where I'm Getting Stuck
I've made an edit.blade to be used to correct any mistakes that would be made while creating an order.
To call back the section that refers to the dates checkboxes I've used the following blade syntax (I know its different from create, mainly due to me trying to fix the problem)
#foreach($orders as $orderkey => $order)
#foreach($days as $day)
{{ Form::hidden($day.'[]', 0, array('id'=> $day.'_hidden_'.$orderkey, 'class' => 'is-checkradio')) }}
{{ Form::checkbox($day.'[]', 1, $order->{$day}, array('id'=> $day.'_'.$orderkey, 'class' => 'is-checkradio')) }}
<label for="<?php echo $day.'_'.$orderkey; ?>"><?php echo $day; ?></label>
#endforeach
#endforeach
OrderController - Update
I've had to use the following in my controller to get the fields to update however whenever a checkbox is left unchecked it will overwrite the next checked value.
$customer = Customer::find($id);
foreach($customer->orders as $key => $order){
$Monday[] = $request->Monday[$key];
};
$updates = array(
'Monday' => $Monday,
);
foreach($updates['orders'] as $k => $update){
$update_order->Monday = $updates['Monday'][$k];
$update_order->save();
};
This part:
foreach($customer->orders as $key => $order){
$Monday[] = $request->Monday[$key];
};
Is creating an array where if the existing data is true and the new data is true, save it. Otherwise delete it. That means any checkboxes that have been deselected will be captured, but any newly checked checkboxes won't be. Is this your intention?
Why not just do:
$updates = array(
'Monday' => $request->Monday,
);
I may not have fully understood your question so please comment and/or amend the Q if you need to clarify further,
Found out how to fix it from Unchecked checkbox returning null value
I needed to add my $orderkey to the name []
So in the end this worked:
#foreach($days as $day)
{{ Form::hidden($day.'['.$orderkey.']', null, array('id'=> $day.'_hidden_'.$orderkey, 'class' => 'is-checkradio')) }}
{{ Form::checkbox($day.'['.$orderkey.']', 1, $order->{$day}, array('id'=> $day.'_'.$orderkey, 'class' => 'is-checkradio')) }}
<label for="<?php echo $day.'_'.$orderkey; ?>"><?php echo $day; ?></label>
#endforeach
what i wants to do is to show the replies that are given to that particular comment on the post.Right now i am able to show the comment to that specific post but the replies are displayed along each comment.
here is the controller part of the code:
public function show($id)
{
$blog = Blog::findOrFail($id);
$comments = Comment::where('blog_id', $id)->get()->all();
$test = Comment::all();
// $comments = Comment::whereIn('blog_id', $id)->get()->all();
$commentReplies = CommentReply::where('comment_id'== $test->id)-
>get();
// $commentReplies = CommentReply::where('comment_id',$blog-
>comment()->id)->get()->all();
return
view('admin/blog/front',compact('blog','comments','commentReplies'));
}
i am saving the refrence to that comment in database in 'comment_id' but when i try to reach the 'comment_id' via $commentReplies it gives me the error of "Property [id] does not exist on this collection instance."
The correct syntax is:
$commentReplies = CommentReply::whereIn('comment_id', $test->pluck('id')->toArray())->get();
You also could use relationships. Define this one in the Comment model:
public function replies()
{
return $this->hasMany(CommentReply::class);
}
Then load comments with replies:
$commentsWithReplies = Comment::with('replies')->get();
And to iterate over comments and replies:
#foreach ($commentsWithReplies as $comment)
{{ $comment->text }}
#foreach ($comment->replies as $reply)
{{ $reply->text }}
#endforeach
#endforeach
You also shouldn't chain ->get()->all(), just use ->get().
And finally, the correct syntax for returning a view is (thanks to #Nikola Gavric):
return view('admin.blog.front', compact('blog', 'comments', 'commentReplies'))
How can I display Organisation value in view, I tried this , but it does not work
Code in Model :
function getOrganisationName($organisation_id){
return $orgaName = $this->find('list',array('conditions' => array('Organisation.id' => $organisation_id), //array of conditions
'fields' => array('Organisation.name')));
}
Code in Controller :
$orgName = $this->Organisation->getOrganisationName($organisation_id);
$this->set(compact('indicators', 'organisations', 'rejections', 'projects', 'organisation_id','orgName'));
code in view :
echo $orgName['organisation']['name'];
Firstly, Code in your view should be
echo $orgName['Organisation']['name'];
Also you can use cakephp findById($id) or find(‘first’) to retrieve your data.
I've customized the edit profile view using template.php and user-profile-form.php
All shows up correctly but the Submit (and Delete) button..
I'm using Adaptive Theme and I've modified like this :
template.php
function adaptivetheme_theme(&$existing, $type, $theme, $path) {
return array(
'user_profile_form' => array(
'template' => 'templates/user-profile-form',
'render element' => 'form',
),
);
}
function adaptivetheme_preprocess_user_profile_form(&$vars) {
$vars['form']['account']['name']['#description'] = t('blabla');
$vars['form']['submit']['#value'] = t('Save profile');
$vars['form']['delete']['#value'] = t('Delete account');
$vars['account'] = drupal_render($vars['form']['account']);
$vars['theme_select'] = drupal_render($vars['form']['theme_select']);
$vars['picture'] = drupal_render($vars['form']['picture']);
$vars['signature_settings'] = drupal_render($vars['form']['signature_settings']);
$vars['contact'] = drupal_render($vars['form']['contact']);
$vars['timezone'] = drupal_render($vars['form']['timezone']);
$vars['submit'] = drupal_render($vars['form']['submit']);
$vars['delete'] = drupal_render($vars['form']['delete']);
}
then in the user-profile-form.tpl.php :
<div id="user-profile-form">
<?php echo $account; ?>
<?php echo $timezone; ?>
<?php echo $submit; ?>
<?php echo $delete; ?>
</div>
The edit form of the account shows correctly. I've tried adding/removing variables successfully (ie the $timezone) but the submit/delete are missing.
I don't know what's wrong..
I've tried to change the name of the variables 'submit' and 'delete' but still no button shows up. Of course I've cleared the cache every times needed (and not).
I have no JS hiding the buttons neither..
I render this form through a custom block in a Panel :
<?
module_load_include('inc', 'user', 'user.pages');
global $user;
print drupal_render(drupal_get_form('user_profile_form', $user));
?>
Maybe a problem with Panels ???
Any idea is appreciated :)
Thx for reading
Erwan
I forgot the "[action]".. :
$vars['submit'] = drupal_render($vars['form']['actions']['submit']);
$vars['cancel'] = drupal_render($vars['form']['actions']['cancel']);
And 'Delete' button didn't show up at first because it's called "cancel", and its #access param was sent to FALSE. Thx DPM ;)
Now, the problem is that when I trigger the submit button, the form is not sent, it justs reload he page. I will update if I manage to solve that too.
The page is only reloading because you forget to render the hidden form elements. To do so in your template preprocess you can use something like that :
function THEME_preprocess_user_profile_form(&$variables) {
$hidden = array();
foreach(element_children($variables['form']) as $key)
{
$type = $variables['form'][$key]['#type'];
if($type == "hidden" || $type == "token"){
$hidden[] = $variables['form'][$key];
}
}
$variables['hidden'] = $hidden;
//Dont forget to report your variables like you already did ...
}
Then when it s done render the $hidden variable in your template file
<?php print render($hidden);?>
And there you go !
I have an order form to purchse a voucher but for some reason now when I click phurcase it displays a blank screen. I cant see what has changed and why the view is not being passed the information from the controller.
Vourchers form
<h2>Vouchers</h2>

$total_price = 0.00;
if(isset($data['Voucher'])) { $this->data['Voucher'] = $data['Voucher']; }
if(isset($this->data['Voucher'])) {
// if we have posted a voucher purchase: add it to session array
if(isset($this->data['Voucher']['slug'])){
$slug = $this->data['Voucher']['slug'];
$voucher = $this->getVoucher($slug);
$voucher['Voucher']['price'] = $this->data['Voucher']['price'];
$vouchers = $this->Session->read('Res.Vouchers'); // read existing voucher orders
if(is_array($vouchers) && isset($voucher['Voucher'])){
$temp['id'] = $voucher['Voucher']['id'];
$temp['title'] = $voucher['Voucher']['title'];
$temp['description'] = $voucher['Voucher']['description'];
$temp['slug'] = $voucher['Voucher']['slug'];
$temp['price'] = $this->data['Voucher']['price'];
$vouchers[] = $temp;

$this->Session->write('Res.Vouchers',$vouchers);
} else {
$vouchers = $this->Session->read('Res.Vouchers'); // read existing voucher orders
}
$this->set('voucher_orders', $vouchers);

In the view, you have this around the whole HTML:
if (isset($voucher)) {
// ...
}
Meaning: display voucher information if there is a voucher, and do not display anything otherwise.
Now, in your controller, you don't seem to be passing a voucher variable to the view (which should be done with $this->set('varname', $var);
So, your view does not get any data, thus it does not display anything.
This could explain your issue. But if the screen is completely blank (not even the layout displays), then you must enable error logging to check what's going on.
You are setting 'voucher_orders' to your view not 'voucher' the name of the variable in the view is always the string passed in the set method. Also I don't quite understand what you are doing in the controller with the $data variable, where does it come from? Also it's redundant doing $this->data['Voucher'] = $data['Voucher'] and the checking $this->data isset if you already checked if $data is set. You might be overwriting your $this->data array, what you are doing is not necessary since the view already gives you a populated $this->data if its a form submission.
You should really try doing some tutorials and reading up a little before jumping in, you seem to not properly understand the CakePHP structure and workflow.
Thanks for all your help. By using the pr() or debug() in the controller I found the problem. It was in the function that was getting called on the line $voucher = $this->getVoucher($slug);. I now have a better understanding of cakephp.
