i have many class in model directory that those are extend of Zend_Db_Table_Abstract.
but i need use of zend_paginator and this need to result of Zend_Db_Select !!
so when i use of this code (productCat is a model class)
$productCat = new ProductCat();
$rows = $productCat->FetchOrderByPriority();
// Get a Paginator object using Zend_Paginator's built-in factory.
$paginator = Zend_Paginator::factory($rows);
$this->view->paginator = $paginator;
it don`t work!
it show me this error :
Catchable fatal error: Object of class Zend_Db_Table_Row could not be converted to string in
this is my view code :
<ul><?php foreach ($this->paginator as $item): ?>
<li><?php echo $item; ?></li><?php endforeach; ?></ul>
is there any idea?
Pagination definitely works. The problem is in your view where you're trying to echo $item.
And it obviously doesn't work since Zend_Paginator::factory($rows) has returned a rowset; so when you're iterating over $paginator object, you're getting objects of Zend_Db_Table_Row type, and you simply cannot echo them.
What you're trying to do, I believe, is to echo a particular property of the item object, something like:
echo $item->name;

I have got an error in zf3:
Error
C:\xampp\htdocs\zf3\module\Application\view\application\index\contact.phtml:21
Message:

You did not post the controller action code but it is possible to say for sure that you are assigning the form property in the view model with a string instead of a Zend\Form instance.
Just check the "form" property within the returned view model.
I'm still trying to get as "hierarchical" view the recordssets of a second tableadapter collection.
In my controlleraction I passed a second argument to the view:
return new ViewModel([
'projects' => $this->projectTable->fetchAll(),
'dcls' => $this->table->fetchAll()
]);
In my view I thought I could grab the second collection as I did with the first:
foreach ($projects as $project) :
?>
<tr>
<td><?= $project['Projectname']?></td>
<td><?= $project['ProjectShortcut']?></td>
<td><?= $project['ProjectCiNumber']?></td>
<td><?= $project['Unitname']?></td>
<td><?= $project['UnitShortcut']?></td>
<td><?= $project['UnitCiNumber']?></td>
<td>
Edit
Delete
</td>
<?php foreach ($dcls->getImportunit($project['UnitID']) as $dcl) : ?>
<td><?= $dcl['Importdate']?></td>
<?php endforeach; ?>
<?php endforeach; ?>
But that doesn't work, I have some understanding issues.
if I try $dcls->getImportunit($project['UnitID']) as $dcl
then I get an error
Call to undefined method Zend\Db\ResultSet\ResultSet::getImportunit()
The method is placed in my model and it is public.
If I call just to try: <?php foreach ($dcls as $dcl) :
<td><?= $dcl['Importdate']?></td>
<?php endforeach; ?>
I get an error
Cannot use object of type Import\Model\Import as array
Interesting I used the same syntax like for projects?
If I use as an object attribut :
<?php foreach ($dcls as $dcl) :
<td><?= $dcl->Importdate?></td>
<?php endforeach; ?>
I get an error
This result is a forward only result set, calling rewind() after moving forward is not supported
This one makes sense for, I just tried different possibilies to get a clue if my dcl Records are usable in my view.
So I have two questions. why can't I grad the columns as an error like I have done with projects.
And why can't I use my method? It seems like the collection dcls is not properly passed.
So besides the little understanding issues my target shall be to scroll through the second collection (dcl) while using a parameter of the first collection (project)
EDIT1: following the suggestions from jobaer
Here first my new code:
Controller/indexAction
$dcls = $this->table->fetchAll();
// make an array for dcl
$secondCollection = array($dcls);
foreach ($dcls as $dcl) {
// if this is a resultset pass into view as you need
$importUnits = $dcl->getImportunit($project['UnitID']);
$secondCollection['importdate'] = $dcl->importdate;
$secondCollection['DCL_Path'] = $dcl->DCL_Path;
}
// pass $secondCollection via model
return new ViewModel([
'projects' => $this->projectTable->fetchAll(),
'dcls' => $secondCollection,
]);
Question: How could this work as how I understand the view gets every recordset of projects and if I here try to get the secondCollection related to UnitID, how can it work in the view? For my understanding the passing to the view is executed only once if I call the route, isn't it? or am I wrong in this case?
This one $importUnits = $dcl->getImportunit($project['UnitID']); in this snipped might have no effect?
Call to undefined method Zend\Db\ResultSet\ResultSet::getImportunit()
This is you are getting because you are not calling that method in a way that should not be.
Cannot use object of type Import\Model\Import as array
You cant call an object as array unless it is implicitly defined to be called as an array inside that class you are calling on.
This result is a forward only result set, calling rewind() after moving forward is not supported
You are getting this because, generally you cant loop over over again for the result set you are returning if you do not rewind the internal pointer to the beginning, this result set uses SPL Iterator.
So to meet this issue you can use buffer() method with the result set before returning it.
public function fetchAll()
{
$resultSet = $this->tableGateway->select();
$resultSet->buffer(); // This is the point here
return $resultSet ;
}
Buffering is a feature of Zend\Db\ResultSet\ResultSet, which you can use to wrap a driver result.
Edit:
Whatever is related to model, you must do that in the model. As you are coming across loop problem with the result sets, you do the trick with the help of the model. What this means is to create an array from the result set in your controller method and then pass it to the view.
For example, you are doing so as the following in the view to fulfill your needs.
foreach ($projects as $project) :
// here you are looping for project
foreach ($dcls as $dcl) :
// Here you want to loop for dcl
endforeach;
endforeach;
But for the above described reason you cant use loop inside another loop.
'projects' => $this->projectTable->fetchAll(),
'dcls' => $this->table->fetchAll()
As you know $projects and $dcls return resultsets. That's why I told you to make arrays from those resultsets in the controller methods.
You already know what to display from $projects and $dcls. So make arrays from resultsets as below
$secondCollection = array();
foreach ($dcls as $dcl) {
$secondCollection['importdate'] = $dcl->importdate;
$secondCollection['DCL_Path'] = $dcl->DCL_Path;
}
Do the same technic for others if you need.
Now if you need any resultset by specific ID or NAME then you should process the thing in your controller method using model's method help. For example
$projects = $this->projectTable->getProjectByUnitId($unitId);
Now you know $projects is also a resultset, so you can make it an array as above.
Then pass all of the arrays made from different resultsets in the view...
return new ViewModel([
'array_name1' => $array_name1,
'array_name_2' => $array_name_2,
]);
Hope this would help you!
I'm trying to get started with Zend Framework , followed the quickstart project and am trying to start a new module of my own.
Am trying to implement view helpers and I keep getting the following message:
Message: Method formDate does not exist
Last entry at the stack trace:
0 D:\work\quickstart_zend\application\views\scripts\users\register.phtml(38): Zend_Form_Element->__call('formDate', Array)
I have the following file structure:
quickstart_zend
+ application
+ configs
+ controllers
[...]
+ views
+ helpers
+ scripts
[...]
+ library
+ Application
+ Form
+ Element
Date.php
+ View
+ Helper
FormDate.php
+ public
I have added in my public/Bootstrap.php this method:
protected function _initActionHelpers()
{
Zend_Controller_Action_HelperBroker::addPath(APPLICATION_PATH.'/../library/Application/View/Helper', 'Application_View_Helper');
Zend_Controller_Action_HelperBroker::addPrefix('Application_View_Helper');
}
I have also added in my application.ini:
autoloaderNamespaces[] = "Application"
resources.view.helperPath.Application_View_Helper = APPLICATION_PATH "/../library/Application/View/Helper/"
And i have seen a version and also have tried with resources.view.helperPath.Application_View_Helper_, nothing seems to get it to work.
Of course, i have a Users.php form where i create a 'date' element:
// Add a dateOfBirth element
$element = new Application_Form_Element_Date('dateOfBirth');
$this->addElement($element);
Of course, i have a Users.php form where i create a 'date' element:
// Add a dateOfBirth element
$element = new Application_Form_Element_Date('dateOfBirth');
$this->addElement($element);
And in my view script, where the errors shows up:
<? echo $form->dateOfBirth->formDate() ?>
What am i missing to get it to work? :-( i've spent a day so far looking for solutions
You are receiving this error because there is no such method in Zend_Form_Element. I think you are trying to use your view helper to display in some way this form element, but if this is the case it is better to use form decorators. You can use the standard decorators or you can create a custom one. Check the documentation for more info - http://framework.zend.com/manual/en/zend.form.decorators.html
to properly use your view helper on that data you would use it like:
In your view (.phtml)
//a view helper should act on a piece of data and return something
//so I assume your formDate() helper takes a date value and reformats it.
<?php echo $this->formDate($this->form->dateOfBirth) ?>
assuming you assigned your form to the view in your controller using the standard:
$this->view->form = $form;
I want to echo the name of the variable object i'm calling, in this case controller_01.
I'm using get_class, but it wont print the variable name, only the object type :(
<?php
class remoteControl{
private $chip = "Intel64<br />";
public function openCase(){
echo "The controler has a " .get_class($this);
return $this->chip;
}
}
$control_01 = new remoteControl();
echo $control_01-> openCase();
?>
You can't do that just like that. An object can have multiple references, but the object isn't itself aware of those references.
The only thing you could do, is to enumerate through every variable you can find and check if it points to the object. But those references could exists also in arrays, or in properties of other objects.
And your design is really flawed if you need the object to find its reference variables this way.
I am quite confused how to use partialLoop
Currently I use
foreach ($childrenTodos as $childTodo) {
echo $this->partial('todos/_row.phtml', array('todo' => $childTodo));
}
$childrenTodos is a Doctrine\ORM\PersistantCollection, $childTodo is a Application\Models\Todo
I tried doing
echo $this->partialLoop('todos/_row.phtml', $childrenTodos)
->setObjectKey('Application\Models\Todo');
But in the partial when I try to access properties/functions of my Todo class, I cant seem to get them always ending up with either call to undefined method Zend_View::myFunction() when I use $this->myFunction() in the partial or if I try $this->todo->getName() I get "Call to a member function getName() on a non-object". How do I use partialLoops?
Try this
echo $this->partialLoop('todos/_row.phtml', $childrenTodos)
->setObjectKey('object');
Then in your partial you can access the object like this
$this->object
object is the name of the variable that an object will be assigned to
You can also do this once in your Bootstrap or other initialization class if you have access to the view object like so
protected function initPartialLoopObject()
{
$this->_view->partialLoop()->setObjectKey('object');
$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer');
$viewRenderer->setView($this->_view);
}
I also had "Call to function on non object" error when trying suggested syntax, seems like they've changed something on later versions of Zend Framework. The following works for me on ZF1.12:
echo $this->partialLoop()
->setObjectKey('object')
->partialLoop('todos/_row.phtml', $childrenTodos);
