Having a Zend_Form with a Zend_Form_Element_Select on it, i can set ONE option selected with setDefault. But how can i select multiple items on that element, like
$this->setDefaults(array('groups' => 5, 'groups', 7));
But this will only select the option with value 7, option with value 5 is still NOT selected :(
($this is zend_form)
a Zend_Form_Element_Select element can only have one value. If you want a multiselect element, you can use Zend_Form_Element_Multiselect. To set the defaults, you can use either:
$this->setDefaults(array('elementName' => array(5, 7)));
or
$this->setDefault('elementName', array(5, 7));

I have data stored in a state that is shown in flatlist, I want to sort the data based on ratings. So if I click on sort button they should be sorted in ascending order and when I click again, they should be sorted in descending order.
I have an array of objects stored in state, below is just a piece of data that is important.
show_data_list = [{ ratings : { overall : 4, ...other stuff } } ]
Is there a way I could do it, I tried using the map function which sorts array
list.map((a,b) => a-b)
But how can I use this to sort my array of objects, I cant pass in 2 item.rating.overall as the parameter.
Thanks in advance for the help :)
You can use javascript's built in sort function. You can provide a custom comparer function for it, which should return a negative value if the first item takes precedence, 0 if they are the same and a positive value if the second value should take precedence.
show_data_list.sort((a, b) => { return a.ratings.overall - b.ratings.overall; }). This will sort the data in the ascending order.
show_data_list.sort((a, b) => { return b.ratings.overall - a.ratings.overall; }). This will sort it in the descending order.
This is how I solved it stored the data in a variable and then sorted it based on condition
let rating = this.state.show_data_list;
rating.sort(function(a,b) {
return a.ratings.Overall < b.ratings.Overall
Try This
Sort your List Ascending/ Descending order with name or other string value in list
const [productSortList, setProductSortList] = useState(productarray);
where productarray is your main array
Ascending
productarray.sort((a, b) => a.products_name < b.products_name)
Descending
productarray.sort((a, b) => b.products_name < a.products_name),
You can reset the state of array you have passed as data in Flatlist
ascending ->
setProductSortList(
productarray.sort((a, b) => a.products_name < b.products_name),
);
do same for descending
How can we filter an ArrayList in Silverstripe 3?
where getVideosfromCategories() returns a merged ArrayList
I need something Like:
$this->getVideosfromCategories()->filter('ID:LessThan', $id)->sort(array('ID' => 'DESC'))->first()
these Filters (filter('ID:LessThan', $id)) only work with DataList ?
How can i filter my ArrayList?
these Filters (filter('ID:LessThan', $id)) only work with DataList ?
Yep, that's correct, search filter modifiers only work on DataList instances.
(https://docs.silverstripe.org/en/3/developer_guides/model/searchfilters/) It's interesting that the documentation does not mention that, I think it should be updated.
(I opened a PR for it https://github.com/silverstripe/silverstripe-framework/pull/9363)
But you can modify your current code to filter by an array of IDs instead, something like this:
$idsWeWant = [];
if ($id > 0) {
$idsWeWant = range(0, $id - 1); // "$id - 1" because you had "LessThan" modifier.
}
$this->getVideosfromCategories()
->filter('ID', $idsWeWant)
->sort(array('ID' => 'DESC'))
->first();
I am looping the rows within $.fn.dataTable.ext.search.push function to select some rows based on many criteria. I am setting some values on the TD of the tables known as orthogonal data. I am trying to get the value of the 'data-sort' but I don't know how. I am able to get the cell's inner data via data[2] (for column 2), but not the 'data-sort' or 'data-filter'. Any ideas?
$.fn.dataTable.ext.search.push(
function (settings, data, dataIndex) {
var iRating = parseFloat(data[2]) || 0; // this works
var datasort = //somehow get the data-sort from the TD
);
HTML
<td data-sort="57000" class=" seqNum">.....</td>
Looks like this way I can get the value. If there are any other better ways please advice:
$(settings.aoData[dataIndex].anCells[2]).data('sort')
Yes there is an easier way.
The data parameter is the "search data" for the row. i.e. the values for "filter" data for each col - not your "sort" data / anything else.
But you also have access to the full data object for the row i.e. the 4th parameter - rowData.
So you need to use rowData at the index of the column you want (you say 'for column 2', zero based so - 2 would be for the 3rd column).
Then you should find a property called 'sort' :
function(settings, searchData, index, rowData, counter){
var dataSort = rowData[1]['sort'];
console.log(`This should be the value you want : ${dataSort}`);
}
As per the documentation here
can i just have listdata by itself? The list doesn't list anything, all I keep getting is "Array" as the return.
I have:
$awards= $model->findAll('uid='.$uid);
return CHtml::listData($awards, 'award_id', '$data->award->name');
try this code:
$awards= $model->findAll(array('condition'=>'uid ='.$uid)); // get records from table
return CHtml::listData($awards, 'award_id', 'award_name'); // third parameter should the array value. Most of the case we use to display in combo box option text.
If you are getting from another table, then declare a variable in your award model.
public $awrd_name;
Then you have to get records using relation in criteria.
Output will be :
array("1" => "award1", "2" => "award2", "3" => "award3");

I need certain pagination variables in my controller action.
such as:
1.Current Page Number
2.Current Page offset
3.total records displayed
i.e. 31 to 40 of 2005 records displayed
I tried the following:
$dataProvider = NodesTerms::getNodesDataFromTerms($nodeId) ;
$pagination = $dataProvider->getPagination();
var_dump($pagination->getPageCount());
//var_dump($pagination->currentPage);
I can get the Pagination Object, but zero (0) in $pagination->currentPage or $pagination->offset etc....
I need this information to dynamically generate meta page title and description on actions with page listings such as pagetitle: page 3 of 10 for American Recipes...
Appreciate any help with this.
Try setting the itemCount explicitly in your dataProvider:
'pagination'=>array(
'pageSize'=>10,
'itemCount'=>$count
)
Or use a new CPagination object:
$pagination = new CPagination($count);
$dataProvider = new CSqlDataProvider($sql, array(
// ... other config
'pagination' => $pagination
));
How this works:
The pagination's itemCount is set during creation of the data-provider and again in CSqlDataProvider's fetchData function:
$pagination->setItemCount($this->getTotalItemCount());
During creation of data-provider only the values passed to the pagination property are used, and if we don't pass itemCount value, then the default of 0 is used.
So if we want to access offset or pageCount or currentPage or itemCount before the call to fetchData we have to set the itemCount explicitly.
However if we want those values after the call to fetchData then the values are already correctly populated due to the call to setItemCount within fetchData.
An example for clarity (without passing itemCount during data-provider creation):
$dataProvider = NodesTerms::getNodesDataFromTerms($nodeId);
$pagination = $dataProvider->getPagination();
var_dump($pagination->getPageCount()); // this will be zero
$data=$dataProvider->getData(); // getData calls fetchData()
var_dump($pagination->getPageCount()); // now this will be correct value
getCurrentPage returns "the zero-based index of the current page"
http://www.yiiframework.com/doc/api/1.1/CPagination#getCurrentPage-detail
so if you're on the first page, it should be returning 0.
And as you know the page size and the total number of records that will be enough for you to generate your page title.
