I am developing a form in a Symfony application where a user must indicate a country, a region and an optional island using HTML select elements.
I have three models: Country, Region and Island; and Symfony has auto-generated three widgets in the form using the sfWidgetFormDoctrineChoice widget:
...
'country_id' => new sfWidgetFormDoctrineChoice(array('model' => $this->getRelatedModelName('Country'), 'add_empty' => false)),
'region_id' => new sfWidgetFormDoctrineChoice(array('model' => $this->getRelatedModelName('Region'), 'add_empty' => false)),
'island_id' => new sfWidgetFormDoctrineChoice(array('model' => $this->getRelatedModelName('Island'), 'add_empty' => true)),
...
Since the country list is large, and so the region list, I've been thinking on filtering the options available in Region and Island according to the value selected in Country.
Doing this after the HTML document is ready is easy with jQuery's change method and a simple AJAX request. But I wonder if there's a way of doing this directly from Symfony, perhaps in form configuration, to have a default combined selection.
Any suggestions?
Thanks!
After playing around with sfDependentSelectPlugin, I ended up assigning custom queries to initialize the HTML select elements:
$countryId = $this->getObject()->getCountry()->getTable()->getDefaultCountryId();
$regionId = $this->getObject()->getRegion()->getTable()->getDefaultRegionId($countryId);
$islandId = $this->getObject()->getIsland()->getTable()->getDefaultIslandId($regionId);
$this->widgetSchema->setDefault('country_id', $countryId);
$this->setWidget('region_id', new sfWidgetFormDoctrineChoice(array(
'model' => $this->getRelatedModelName('Region'),
'query' => $this->getObject()->getRegion()->getTable()->getRegionsQuery($countryId),
'default' => $regionId,
)));
$this->setWidget('island_id', new sfWidgetFormDoctrineChoice(array(
'model' => $this->getRelatedModelName('Island'),
'query' => $this->getObject()->getIsland()->getTable()->getIslandsQuery($regionId),
'add_empty' => '---',
'default' => $islandId,
)));
And then updating the options available with AJAX requests using jQuery. The good thing is that the actions that handle the AJAX requests use the same query methods above to return a new set of results.

In a custom drupal 9 module I define a new field for a view within hook_views_data_alter(&$data).
$data['node']['node_views_mydata'] = array(
'title' => t('Node Views Mydata'),
'field' => array(
'title' => t('Node views mydata'),
'help' => t('Shows some data in views'),
'id' => 'node_views_mydata',
'sort' => [
'node_views_mydata' => 'default',
],
)
);
I have also defined a field plugin processing text data for this field, and can insert and output the field in views.
Now I would like to make the field sortable. But I can't do that. I always get the error "unknown column". In fact, node_views_data is not a "real" node field, but only created on the fly via the hook.
Is there nevertheless a way to sort by this column?
I have a form field, when I select a car, I want to get the type of car or the result of the model.
$this->crud->addField([
'name' => 'car_id',
'label' => 'Car',
'type' => 'select2_from_ajax',
'attribute' => 'name',
'model' => Car::class,
'data_source' => url('admin/api/cars'),
'placeholder' => 'Search and select a car',
'minimum_input_length' => 2,
]);
And how do I use the result to determine which other fields to show in the form?
You can do that in Backpack v5 using the included CrudField JS Library. To hide/show other fields depending on card_id, you should:
Step 1. In your setupCreateOperation() and/or setupUpdateOperation() load a new JS file:
Widget::add()->type('script')->content('assets/js/admin/forms/product.js');
Step 2. Create that JS file. Inside it, you can now easily select and get the value of Backpack fields. To show/hide other fields depending on car_id:
crud.field('car_id').onChange(function(field) {
// eg. show "car_model" if "car_id" is 1
crud.field('car_model').show(field.value == 1);
}).change();
For more things you can do with the CrudField JS Library, check out its docs.
I am trying to make a custom filter based on another module in sugarCRM 8.0.1.
I have a module Ev_Registrations that has one Ev_Event and one Contact, the tables are:
ev_registrations
ev_registrations_contacts_c
ev_registrations_ev_events_c
How do I make a dropdown for event or contact on the list page as highlighted below?
I've tried making a custom filter, and managed to get it showing up in the list, however, it doesn't seem to be actually filtering by the event name.
$viewdefs['EV_Registrations']['base']['filter']['basic']['filters'][] = array(
'id' => 'filterRegistrationByEvent',
'name' => 'LBL_FILTER_REGISTRATION_BY_EVENT',
'filter_definition' => array(
array(
'ev_registrations_ev_events_c.ev_events.name' => '2019 Foo Bar Event',
),
),
'editable' => false,
'is_template' => false,
);
How can users add products to a simple plugin config using an autocomplete field?
I tried to use Config Entity but it looks the same as Form API (and I can't use entity fields there).
I was able to do this in Drupal 8 using the form API and the entity_autocomplete type.
$form['stories'] = [
'#type' => 'entity_autocomplete',
'#target_type' => 'node',
'#title' => $this->t('Stories'),
'#description' => $this->t('Select some stories.'),
'#default_value' => $default_entities,
'#tags' => TRUE,
'#selection_settings' => array(
'target_bundles' => array('page', 'article'),
),
'#weight' => '0',
];
Use webform - there is an entity reference field.
This won't be useable for your purpose .. but you can check the source for sake.
I have a form I created in a custom module using the Form API. It is a fairly basic form with only 4 fields. It basically signs a user up for a job alert system. We are basing it only by email address with a few search parameters. We want people to be able to setup a search agent quickly and anonymously meaning they will NOT be creating a Drupal user account as we don't want them to have to deal with a password etc. They will just put in their email address, check off a few preferences and we will save the data.
Now the issue I need to deal with is allowing the user to edit their preferences later on and/or unsubscribe. Again this is not high security and it doesn't need to be. What I would like to do is initially ask ONLY for their email address in the form and allow them to submit it. I would then check the database to see if we already have an entry for that email address and if so, display the pre-filled form for them to edit or unsubsribe, other wise just show them the blank form. So I am just trying to figure out the best way to go about this. I'm thinking I just have one form with all of the fields including email address, but somehow only display the other fields besides the email address after a successful call to the database. I'm just tripping up on how to accomplish this.
EDIT:
I'm wondering if I can use Drupal's AJAX functionality to accomplish this? I tried this, but I couldn't get it to work. I put an Ajax attribute on my submit button with a wrapper ID and a callback function. I created a form element in my form with blank markup and used a prefix and suffix that created a wrapper div with the ID I used in my AJAX parameter. Then I am thinking in my callback function I can do the database lookup and then return the form elements I need either pre-filled or not into the wrapper div that was created, but when I do this, the form does submit via AJAX and I get the spinning wheel, but no matter what I return in my callback, it does not appear in my output wrapper div. Am I going about this the right way? I also made sure I have $form_state['rebuild'] = TRUE; on my original form.
Here is what I tried and it didn't work.
/**
* Implements hook_form().
*/
function _vista_form($form, &$form_state) {
$form = array();
$form_state['rebuild'] = TRUE;
$form['email'] = array(
'#type' => 'textfield',
'#title' => 'Email',
'#required' => TRUE,
);
$form['render_area'] = array(
'#type' => 'markup',
'#markup' => '',
'#prefix' => '<div id="job-agent-form">',
'#suffix' => '</div>',
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Submit'),
'#attributes' => array('class' => array('submit')),
'#ajax' => array(
'callback' => '_display_form',
'wrapper' => 'job-agent-form',
'method' => 'replace',
'effect' => 'fade',
),
return $form;
}
function _display_form($form, &$form_state) {
// there are other form elements that would go here also, I just added two for example
$type_options = array(
'VISTA-HealthCare-Partners-Government' => 'Vista Healthcare Partners',
'International' => 'International Locum Tenens',
'Permanent' => 'Permanent Physician',
'US-Locum-Tenens' => 'US Locum Tenens',
);
$form['job_type'] = array(
'#type' => 'checkboxes',
'#multiple' => TRUE,
'#title' => 'Type of Job',
'#options' => $type_options,
'#empty_option' => 'Choose a placement type',
'#empty_value' => 'all',
//'#default_value' => $type_selected,
);
$form['active'] = array(
'#type' => 'checkbox',
'#title' => 'Subscribe/Unsubscribe',
'#default_value' => 1,
);
return $form;
}
I would go for creating all fields in the form than use hook_form_alter() to hide the unneeded ones with ['#access'] = FALSE.
