I have created a custom "Meta title" field in Magento for CMS pages. The field displays on the admin and saves to the db, but I'm having trouble retrieving this information. I'm using the model/observer method.
Observer class
public function cmsField($observer)
{
// $model = Mage::registry('cms_page');
$form = $observer->getEvent()->getForm();
$fieldset = $form->addFieldset('example_metainfo_fieldset', array('legend'=>Mage::helper('cms')->__('Meta Info'),'class'=>'fieldset-wide'));
//add new field
$fieldset->addField('metatitle', 'text', array(
'name' => 'metatitle',
'label' => Mage::helper('cms')->__('Metatitle'),
'title' => Mage::helper('cms')->__('Metatitle'),
'disabled' => false,
//set field value
// 'value' => $model->getMetatitle()
));
$form->setValues(Mage::registry('cms_page')->getData());
}
do I need to add some other method to retrieve this value then? Or what is the best/most efficient way to display this information on the frontend? I've tried various approaches, but none have worked so far.

I created a custom content element with a custom field.
I added the custom field like this in the overrides of tt_content.php
$elements = [
'myCustomField' => [
'exclude' => true,
'label' => 'The label of my field',
'config' => [
'type' => 'select',
'renderType' => 'selectSingle',
'foreign_table' => 'tx_vendor_domain_model_myfavoritepictures,
],
],
],
];
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns('tt_content', $elements);
This field is included in the TCA of my custom content element, it stores the relations to chosen records which contain pictures.
The fluidtemplate of my custom content elements contains only a debug-viewhelper.
What I am trying to achieve is to fetch the pictures of the records, which are chosen in myCustomField. For that, I tried to use the "DatabaseQueryProcessor" as described in the official TYPO3 documentation: https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/ContentObjects/Fluidtemplate/DataProcessing/DatabaseQueryProcessor.html
ce_mycustomcontentelement < lib.customContentElement
ce_mycustomcontentelement {
templateName = CeMyCustomContentElement
dataProcessing.10 = TYPO3\CMS\Frontend\DataProcessing\DatabaseQueryProcessor
dataProcessing.10 {
if.isTrue.field = myCustomField
table = tx_vendor_domain_model_myfavoritepictures
as = myFavoritePictures
// recursively process the files in the records with the FilesProcessor
dataProcessing {
10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
10 {
references.fieldName = picture
}
}
}
}
However, for the field "myFavoritePictures" which is defined in the dataProcessing Property, I am getting an empty array from the debug-viewhelper in my fluidtemplate of my custom content element. I am guessing, that i didn't cofigured the dataProcessing porperty correctly but unfortunately I don't know what might me wrong.
I'm developing a prestashop module and I'm trying to show a category tree in my backoffice configuration page.
I'm trying to follow this instructions below but I don't know exactly where to add this code.
It should be inside main module's php? or inside a separate .php file and call it from the main one (don't know how to do it either).
As much time I'm spending trying to figure out, how to implement the code in the link above, the more I think I'm losing my time.
I see that "use" files, and this JS, " /admin-dev/themes/new-theme/js/components/form/choice-tree.js " are not in any prestashop folders.
Well, you should invest some time and learn Symfony since this is what you need to build backend modules for Prestashop 1.7.
As a pointer, you need to create a form class extending the CommonAbstractType, add a build form method. e.g. :
public function buildForm(FormBuilderInterface $builder, array $options)
{
$this->context = Context::getContext();
$parents = [
['id_category' => 2, 'name' => 'Home', 'children' => $this->getSubCategories(1, true, 2)]
];
$builder->add('category', CategoryChoiceTreeType::class, [
'choices_tree' => $parents,
'choice_value' => 'id_category',
'choice_children' => 'children',
'choice_label' => 'name',
'disabled_values' => $disabledCategories,
'label' => 'Choose a category'
])
then add methods for retrieving the data to populate the form fields.
Then use this class in your controller and display the form:
$form = $this->createForm(YourFormForm::class);
Also add a processForm to process data.
As mentioned, this is not a copy/paste situation you need to understand the Symfony workflow.
The only way that I found to "paint" the categorytree in my configuration page is adding this code to the inputs form array:
Can anyone tell me how to retrieve users selection data to my database?
It does not work as any other form field.
array(
'type' => 'categories',
'label' => $this->l('Destination Category'),
'desc' => $this->l('Select ONE Category'),
'name' => 'CATEGORY_CATEGORY_TO',
'tree' => [
// 'selected_categories' => [],
'disabled_categories' => null,
'use_search' => false,
'use_checkbox' => false,
'id' => 'id_category_tree',
],
'required' => true
),
Well, it is SOLVED!!!! Finally it was very simple, but you must get the correct info for you particular case.
#Robertino's answer might be the best implementation, I don't know, but it became impossible to solve for me,
I uses this code below, and called $categoryTree from the form input. This input must be type=> categories_select
Thanks for your time, and for the help of another post from this forum.
$root = Category::getRootCategory();
//Generating the tree
$tree = new HelperTreeCategories('categories_1'); //The string in param is the ID used by the generated tree
$tree->setUseCheckBox(false)
->setAttribute('is_category_filter', $root->id)
->setRootCategory($root->id)
->setSelectedCategories(array((int)Configuration::get('CATEGORY_1'))) //if you wanted to be pre-carged
->setInputName('CATEGORY_1'); //Set the name of input. The option "name" of $fields_form doesn't seem to work with "categories_select" type
$categoryTree = $tree->render();
And the Form:
array(
'type' => 'categories_select',
'label' => $this->l('Category'),
'desc' => $this->l('Select Category '),
'name' => 'CATEGORY_1', //No ho podem treure si no, no passa la variable al configuration
'category_tree' => $categoryTree, //This is the category_tree called in form.tpl
'required' => true
I'm new to symfony. I have a drop down in a form with data fetched from DB.
$builder->add('category', 'entity', array(
'label' => 'category',
'class' => 'MyBundle:category',
'expanded' => false,
'multiple' => false,
'mapped' => false,
'empty_value' => 'category'
));
$builder->add('other_category', 'text', array(
'label' => 'category',
'required' => false,
'invalid_message' => 'Please enter a valid category',
'mapped' => false,
));
the user can also add new category to the table. when other is selected from drop down, the 'other_category' input field is shown, else its hidden.
'Other' was added to drop down with the help of this code.
public function finishView(FormView $view, FormInterface $form, array $options)
{
$new_choice = new ChoiceView(array(), 'other', 'Other');
$view->children['category']->vars['choices'][] = $new_choice;
}
If a option is selected from drop down the form works fine. Data gets stored without any error. But if user selects 'other' and enters a new category the page reloads with 'This value is no valid' under the category options and there is no form validation for the 'other_category' entered by user.
Can someone help me with the form validation and also entering of a new category or suggest a better way to implement the above functionality.
The validation error is happening because the form field type is Entity, but there is no "MyBundle:category" entity with the identifying value "other".
You've not specified the "choice_label" property in your Entity form type so I'll assume your "MyBundle:category" entity has a __toString() function. This would mean none of the "MyBundle:category" entities return "other" in their __toString() function.
I can think of two options to work around this right now:
1) Add a "MyBundle:category" entity with value "other". This is the easiest way, but it's fairly assumed you don't want such a category to exist in your database.
2) Load the list of "MyBundle:category" entities in advance from your controller, build them into an associative array, append your "other" option to the array, then pass that array to the form. You'd need to swap the Entity form type for a Choice type and use the categories array as the choices.
If your form is a FormType class you'll need to pass the array in with the class constructor.
If you don't mind having a new category with an "other" value in your category table, just add it. Otherwise go for option 2, which won't make much difference to what you do after receiving the submitted form as this form field isn't mapped to an entity property anyway.
I have added a new field to my database. I also have managed to add necessary codes and functions in catalog section. This new field is related to the customer. The data related to this new field gets added successfully to the database.
This new field belongs to Customer table.
Now, I want to know, when viewing customer's details in the admin section, how this new field should be retrieved from database? I mean which file should be edited for this purpose?
getCustomer($customer_id) and getCustomers($data = array()) are the functions used to get customer data.
Since they are SELECT * querys your field is being processed automatically.
Afterwards you need to go in the Controller section in the controller\sale folder and there you have customer.php, custom_field.php and and edit the ones that you need. For example:
$this->data['customers'][] = array(
'customer_id' => $result['customer_id'],
'name' => $result['name'],
'email' => $result['email'],
'customer_group' => $result['customer_group'],
'status' => ($result['status'] ? $this->language->get('text_enabled') : $this->language->get('text_disabled')),
'approved' => ($result['approved'] ? $this->language->get('text_yes') : $this->language->get('text_no')),
'ip' => $result['ip'],
'date_added' => date($this->language->get('date_format_short'), strtotime($result['date_added'])),
'selected' => isset($this->request->post['selected']) && in_array($result['customer_id'], $this->request->post['selected']),
'action' => $action
);
add your field in this array (this is from customer.php).
And finally edit the .tpl files that are called from the view\template\sale folder so they appear where they want them to.
Hope i was clear enough.
I am slowly building up my Zend skills by building some utility websites for my own use. I have been using Zend Forms and Form validation and so far have been happy that I have been understanding the Zend way of doing things. However I am a bit confused with how to use Zend_Validate_Db_NoRecordExists() in the context of an edit form and a field that maps to database column that has to be unique.
For example using this simple table
TABLE Test
(
ID INT AUTO_INCREMENT,
Data INT UNIQUE
);
If I was simply adding a new row to the Table Test, I could add a validator to the Zend Form element for the Data field as such:
$data = new Zend_Form_Element_Text('Data');
$data->addValidator( new Zend_Validate_Db_NoRecordExists('Test', 'Data') )
At form validation this validator will check that the contents of the Data element does not already exist in the table. Thus the insert into Test can go ahead without violating the Data fields UNIQUE qualifier.
However the situation is different when editing an existing row of the Test table. In that case the validator needs to check that the element value meets one of two mutually exclusive conditions conditions:
The user has changed the element value, and the new value does not currently
exist in the table.
The user has Not changed the element value. Thus the value does currently exist in the table (and this is OK).
The Zend Validation Docs talk about adding a parameter to the NoRecordExists() validator for the purpose of excluding records from the validation process. The idea being to "validate the table looking for any matching rows, but ignore any hits where the a field has this specific value". Such a use case is what is needed for the validating the element when editing a table. The pseudo code to do this in 1.9 is like so (actually I got this from the 1.9 source code - I think the current docs may be wrong):
$data = new Zend_Form_Element_Text('Data');
$data->addValidator( new Zend_Validate_Db_NoRecordExists('Test', 'Data',
array ('field'=>'Data', 'Value'=> $Value) );
The problem is that the value that is to be excluded ($Value) is bound to the validator at the time it is instantiated (also when the form is instantiated). But when the form is editing a record, that value needs to be bound to the contents of the $data field when the form was initially populated with data - IE the Data value initially read from the Test table row. But in typical Zend patterns a form is instantiated and populated in two separate steps which precludes binding the exclude value to the desired element value.
The following Zend psuedo code marks where I would like the binding of $Value to the NoRecordExists() validator to occur (and note that this is a common Zend controller pattern):
$form = new Form()
if (is Post) {
$formData = GetPostData()
if ($form->isValid($formData)) {
Update Table with $formData
Redirect out of here
} else {
$form->populate($formData)
}
} else {
$RowData = Get Data from Table
$form->populate($RowData) <=== This is where I want ('value' => $Value) bound
}
I could sub-class Zend_Form and override the populate() method to do a one-shot insertion of the NoRecordExists() validator on initial form population, but that seems like a huge hack to me. So I wanted to know what other people think and is there some pattern already written down that solves this problem?
Edit 2009-02-04
I've been thinking that the only decent solution to this problem is to write a custom validator and forget about the Zend version. My form has the record ID as hidden field, so that given the table and column names I could craft some SQL to test for uniqueness and exclude the row with an ID of such an such. Of course this started me thinking about how I would be tying the form to the dB layer that the Model is supposed to hide!
This is how it's done:
I your FORM, you add this validator (for example email field):
$email->addValidator('Db_NoRecordExists', true, array('table' => 'user', 'field' => 'email'));
Don't add custom error message for this since after that it didn't work for me, e.g.:
$email->getValidator('Db_NoRecordExists')->setMessage('This email is already registered.');
In your Controller add this:
/* Don't check for Db_NoRecordExists if editing the same field */
$form->getElement('email')
->addValidator('Db_NoRecordExists',
false,
array('table' => 'user',
'field' => 'email',
'exclude' => array ('field' => 'id', 'value' => $this->request->get('id'))));
And after this you do verifications, e.g.:
if ($this->getRequest()->isPost())
{
if($form->isValid($this->getRequest()->getPost()))
{
....
That's it!
This will also work :
$this->addElement('text', 'email', array(
'label' => 'Your email address:',
'required' => true,
'filters' => array('StringTrim'),
'validators' => array(
'EmailAddress',
array('Db_NoRecordExists', true, array(
'table' => 'guestbook',
'field' => 'email',
'messages' => array(
'recordFound' => 'Email already taken'
)
)
)
)
));
After reviewing the overwhelming response I've decided that I'm going with a custom validator
Look at this one:
Answer raised by me and well-solved by Dickie
private $_id;
public function setId($id=null)
{
$this->_id=$id;
}
public function init()
{
.....
if(isset($this->_id)){
$email->addValidator('Db_NoRecordExists', false, array('table' => 'user', 'field' => 'email','exclude' => array ('field' => 'id', 'value' => $this->_id) ));
$email->getValidator('Db_NoRecordExists')->setMessage('This email is already registered.');
}
Now u can use:
$form = new Form_Test(array('id'=>$id));
You could just call $form->getElement('input')->removeValidator('Zend_Validator_Db_NoRecordExists'); instead of supplying the exclusion.
I have just tried this example for email address uniqueness and it works perfectly with below stuffs :
1] In my form:
// Add an email element
$this->addElement('text', 'email', array(
'label' => 'Email :',
'required' => true,
'filters' => array('StringTrim'),
'validators' => array(
'EmailAddress',
)
));
Here's something special that I needed to add for unique email address to work:
$email = new Zend_Form_Element_Text('email');
$email->addValidator('Db_NoRecordExists', true, array('table' => 'guestbook', 'field' => 'email'));
2] In my controller:
$form->getElement('email')
->addValidator('Db_NoRecordExists',
false,
array('table' => 'guestbook',
'field' => 'email',
'exclude' => array ('field' => 'id', 'value' => $request->get('id'))));
if ($this->getRequest()->isPost()) {
if ($form->isValid($request->getPost())) {
Hope it helps you people !
Thanks
