I am trying to use GridField to allow CMS users to add information (Mailing Lists) to an article of the same page type (Shows) but every new page that's created is already populated with information from previous articles.
I think it may have something to do with the way I've set up the relationships between the Shows page type and the Mailing List DataObject but I can't figure out what I need to do for every new show page to have it's own blank GridField as the mailing list isn't the same for every show...
I've tried many combinations of $has_one, $has_many & $many_many on the two files but nothing gets it working the way I need it to which is for every Show page to have it's own GridField (Mailing List)...
The code I have at the moment is:
Shows.php
private static $has_many = array(
'MailingLists' => 'MailingList'
);
...
$config = GridFieldConfig_RelationEditor::create();
$gridField = new GridField('MailingList',
'Shows Mailing List',
new DataList('MailingList'),
$config
);
$fields->addFieldsToTab('Root.Content.MailingList', array(
$gridField
));
MailingList.php
class MailingList extends DataObject {
private static $db = array(
'Title' => 'Varchar(25)',
'Description' => 'Varchar(55)'
);
private static $has_one = array(
'Shows' => 'Shows'
);
}
With this code
$gridField = new GridField('MailingList',
'Shows Mailing List',
new DataList('MailingList'),
$config
);
you select all records in the MailingList table with new DataList('MailingList'), but you should use related list of records with $this->MailingLists()
$gridField = new GridField('MailingList',
'Shows Mailing List',
$this->MailingLists(),
$config
);

I would like to implement a layout in which a column is repeated several times and can be specified as dynamic content in the CMS. However, I cannot find an object type that would fit for this.
Do I have to specify the input fields individually for each column?
private static $db = [
'Intro_Headline' => 'Varchar',
'Intro_Subheadline' => 'Varchar',
'Intro_Text' => 'HTMLText',
'Intro_Headline2' => 'Varchar',
'Intro_Subheadline2' => 'Varchar',
'Intro_Text2' => 'HTMLText',
...
];
--
$fields = parent::getCMSFields();
//Intro Field 1
$fields->addFieldToTab('Root.Intro', TextField::create('Intro_Headline', 'Headline'), 'Content');
$fields->addFieldtoTab('Root.Intro', TextField::create('Intro_Subheadline', 'Subheadline'), 'Content');
$fields->addFieldToTab('Root.Intro', HTMLEditorField::create('Intro_Text', 'Text'), 'Content');
//Intro Field 2
$fields->addFieldToTab('Root.Intro', TextField::create('Intro_Headline2', 'Headline'), 'Content');
$fields->addFieldtoTab('Root.Intro', TextField::create('Intro_Subheadline2', 'Subheadline'), 'Content');
$fields->addFieldToTab('Root.Intro', HTMLEditorField::create('Intro_Text2', 'Text'), 'Content');
...
Or can someone tell me which field type I can't find?
Update:
Now I have a $has_many variable in addition to my $db variable in my page-model:
private static $has_many = [
'Intro_Columns' => IntroColumn::class,
];
In the getCMSFields() function I add them like this:
$fields->addFieldToTab('Root.Columns', GridField::create('Intro_Columns', 'Columns', IntroColumn::get()), 'Content');
And my data object looks like this:
class IntroColumn extends DataObject
{
private static $db = [
'img_url' => 'Text',
'headline' => 'Varchar',
'subheadline' => 'Varchar',
'text' => 'Text',
'link' => 'Text'
];
}
But the fields are not yet displayed in the CMS. How do I output the data fields from a data object?
For things to be repeatable, you will have to put them into a different object, and then link multiple of those objects to your current object/page.
GridFIeld
The default way of doing this in SilverStripe 4 is using the built in Database Relation ($has_many or $many_many instead of $db) and GridField` as the form field.
I'd recommend you go through this tutorial: https://docs.silverstripe.org/en/4/developer_guides/model/relations/
In paticular the section about $has_many will apply to your usecase. (Example where 1 Team has multiple Players or 1 Company multiple People)
$has_many/$many_many is a very generic option and can be used for any number of possible database relation (linking Categories, Images, Pages, ...)
elemental module
Another option is an officially supported module called elemental. This is very specifically built for repeatable content.
https://github.com/silverstripe/silverstripe-elemental
serialized-dataobject module
Probably not ideal for your usecase, but I maintain a module that provides an alternative to GridField, but it's more suitable for small form fields. The HTMLEditor is to large to be useful in this module.
https://github.com/Zauberfisch/silverstripe-serialized-dataobject
PS: regardless of what way you go, I highly recommend you go through the tutorial from (1.). It's a pretty important fundamental functionality of SilverStripe.
EDIT: response to your updated question:
If you are using GridField, I'd recommend the following:
class Page extends SiteTree {
private static $has_many = [
'Intro_Columns' => IntroColumn::class,
];
public function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab('Root.Columns', new GridField(
'Intro_Columns',
'My Columns',
$this->Intro_Columns(),
new GridFieldConfig_RecordEditor()
), 'Content');
return $fields;
}
}
class IntroColumn extends DataObject {
private static $db = [
'headline' => 'Varchar',
'subheadline' => 'Varchar',
'text' => 'Text',
'link' => 'Text'
];
private static $has_one = [
'Image' => 'Image',
]
public function getCMSFields() {
$fields = new FieldList();
$fields->push(new TextField('headline', 'My Headline'));
$fields->push(new TextField('subheadline', 'My Subheadline'));
// ... and so on
$fields->push(new UploadField('Image', 'Upload an image'));
return $fields;
}
}
Note that I am using $this->Intro_Columns() as the Value for the GridField and not IntroColumn::get(). Because $this->Intro_Columns() is a automatically generated Method that returns all IntroColumn objects linked to the current page. But $this->Intro_Columns() would return all IntroColumns from all Pages
In the template, you cal also access this automatically generated method:
<!-- Page.ss -->
<h1>Page Title: $Title</h1>
<div class="intro-columns">
<% loop $Intro_Columns %>
<div class="intro-column">
<!-- here we are scoped into a single IntroColumn, so you can use all DB fields and methods of that object -->
<h2>$headline <br> $subheadline</h2>
$Image.URL <br>
...
</div>
<% end_loop %>
</div>
In Drupal 7, is it possible to show a result of a DB query on each users' respective profile page, in some table? I need to do this programmatically within my existing module. So the input to the query would be the ID of a user whose profile is currently being viewed.
Only to show the queried data - no administration, no edits, nothing else.
something along the lines of.. (image)
Also the block or field or whatever would make this possible needs to be configurable through the _permission() hook as to who can or cannot view it.
I thought since this is basically just a query with no extra custom stuff there would be an easy way via the Drupal API.
you can create custom block for that and view it in current user profile
/**
* Implements hook_block_info().
*/
function custom_block_block_info() {
$blocks = array();
$blocks['my_block'] = array(
'info' => t('My Custom Block'),
'status' => TRUE,
'region' => 'Content',
'visibility' => BLOCK_VISIBILITY_LISTED,
'pages' => 'user/*',
);
return $blocks;
}
/**
* Implements hook_block_view().
*/
function custom_block_view($delta = '')
{
// The $delta parameter tells us which block is being requested.
switch ($delta)
{
case 'my_block':
// Create your block content here
$block['subject'] = t('This is just a test block created programatically');
$block['content'] = _user_detail_list();
break;
}
return $block;
}
/**
* Implements costome code we want to print().
*/
function _user_detail_list(){
//enter your query and output in some variable
$value = "<p>User Detail</p>"
return $value;
}
Note :- Here profile is extended with new block
There will be some coding to get what you want, but if you just want style/show the data that's already available with the "user" object then #1 below will do it.
Easy way(#1):
1. Create a view and choose the "user" info that you need shown and give it a path. Then in your sub-theme use the correct template -see the code snippets.
https://www.drupal.org/forum/support/post-installation/2011-04-04/modify-the-default-profile-pagelayout
other ways:
use the user-profile.tpl.php see
https://api.drupal.org/api/drupal/modules%21user%21user-profile.tpl.php/7.x
in your module, you need to call and reach out to the hook_user_view.
https://api.drupal.org/api/drupal/modules%21user%21user.api.php/function/hook_user_view/7.x
Here you fetch user profile data from database then follow it
function modulename_menu() {
$items['user-data'] = array(
'title' => 'User data',
'page callback' => 'user_data',
'access callback' => ('user_is_logged_in'),
'#type' => MENU_NORMAL_ITEM,
);
return $items;
}
function user_data(){
global $user;
$user_fields = user_load($user->uid);
$output = "" //return those $user_fields values into table using theme('table',header,rows)
return $output;
}
https://www.drupal.org/node/156863 (for create table view)
i.e
global $user;
$user_fields = user_load($user->uid);
$firstname = $user_fields->field_firstname['und']['0']['value'];
$lastname = $user_fields->field_lastname['und']['0']['value'];
I've run into a very bizarre issue while creating 2 TreeDropdownFields for a DataObject. For some reason, only 1 of the 2 TreeDropdownFields render correctly in the SilverStripe admin. The other doesn't render as a TreeDropdownField at all but just as a label:
Here is the code:
class HomeBanner extends DataObject {
public static $db = array(
'SortOrder' => 'Int',
'Title' => 'Varchar'
);
public static $has_one = array(
'Image' => 'Image',
'SecondaryImage' => 'Image',
'FirstLink' => 'SiteTree',
'SecondLink' => 'SiteTree'
);
public function getCMSFields() {
$fields = parent::getCMSFields();
$fields->removeFieldFromTab('Root.Main', 'PageID');
$fields->removeFieldFromTab('Root.Main', 'SortOrder');
$fields->addFieldToTab('Root.Main', new TreeDropdownField('FirstLinkID', 'First Link', 'SiteTree'));
$fields->addFieldToTab('Root.Main', new TreeDropdownField('SecondLinkID', 'Second Link', 'SiteTree'));
return $fields;
}
public static $summary_fields = array(
'ID' => 'ID',
'Title' => 'Title',
'Thumbnail' => 'Thumbnail'
);
public function getThumbnail() {
return $this->Image()->CMSThumbnail();
}
}
Here is what I have tried so far:
running dev/build/?flush=true
running ?flush=all and ?flush=1
logging out and logging back in after the dev/build + flushes
logging into the admin in another browser (I typically use Chrome but
logged into the site's admin on FireFox and saw the same problem)
The error logs report nothing -- they're clear
There are no errors in the console for Chrome's dev tools
Adding a third TreeDropdownField will allow the first 2 to render
properly but the third one will just show a label instead of a
TreeDropdownField
This format works, but doesn't save whatever is selected--it clears your choice as soon as you leave the page. Also, it deletes all that was saved already in the admin unless I remove it. I can't make changes or else the items saved get removed.):
$fields->addFieldToTab('Root.Main', new TreeDropdownField('SecondLink', 'Second Link', 'SiteTree', 'ID'));
Does anyone have any ideas as to why this could be happening? It doesn't seem to make sense that you can't have multiple TreeDropdownFields.
Reposting as this turned out to be the answer:
The name “HomeBanner” suggests to me that there should also be a has_one pointing back to HomePage or similar? The cause of this is probably that SilverStripe is automatically trying to set one of the has_one relations to point back to the page that the banner belongs to.
Similar conflicts can also happen when using code like this:
class Page extends SiteTree {
private static $has_many = [
'Banners' => 'Banner'
];
}
class Banner extends DataObject {
private static $has_one = [
'Page' => 'Page',
'LinkedPage' => 'Page'
];
}
As SilverStripe doesn't know whether it should use PageID or LinkedPageID to auto-populate that side of the has_many relation (GridField will try to automatically assign the correct has_one ID).
In these cases, you can use dot-notation to distinguish between them - you’d change it to $has_many = ['Banners' => 'Banner.Page'];. See https://docs.silverstripe.org/en/3/developer_guides/model/relations/#has-many for more info.
Does silverstripe have recursive data relationships? I tried to implement it and it gives no errors but the page is blank on modeladmin.
Example has_one recursive relation on Product to itself:
class Product extends DataObject {
private static $db = array(
'Name' => 'Varchar',
'ProductCode' => 'Varchar',
'Price' => 'Currency'
);
private static $has_one = array(
'Product' => 'Product'
);
}
Yes, this is possible.
There can be problems when doing this with Many_Many relationships, though.
My answer would be "no" for this done in this way. Where I've need this in the past I've created the "has one" as an "int" in the db array...
class Product extends DataObject {
private static $db = array(
'Name' => 'Varchar',
'MyProductID' => 'Int',
);
}
this means I've had to add casting for the summary field, custom scaffolding for the search fields and in the getCMSFields to replaceField the int field for a DropdownField to select a product.
I want to know how to correctly save values selected with a ListboxField.
new ListboxField(
$name = "Categorie",
$title = "Catégorie(s)",
Categories::get()->map('ID','Title'),
$value = 1,
$size = 4,
$multiple = true
);
In my example, I can save more than one category to a $db field. I am using:
private static $db = array(
'Categorie' => 'Varchar'
);
It works, but when I'm trying to get back categories names into a template it dosen't work at all. The data stored for example is "1,4,9".
Is there a better way to store variables from ListboxField?
3dgoo is correct that you're probably best using a has_many or many_many relationship here. If for some reason you need to use a single text field, you would just need to manually add a method to your model to look up those related records:
public function getCategories() {
if (empty($this->Categorie)) return null;
return Categories::get()->filter('ID', explode(',', $this->Categorie));
}
You can then do something like the following in your template:
<% loop $Categories %><li>$Title</li><% end_loop %>
Use a $many_many relationship instead of a $db variable to manage your relationship between your object and Categories.
private static $many_many = array(
'Categories' => 'Categories'
);
public function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab('Root.Main', ListboxField::create(
'Categories',
'Catégories',
Categories::get()->map('ID', 'Title')->toArray(),
1,
4,
true
));
return $fields;
}
