I am trying to use yadcf plugin for multiselect plugin in my datatable since it is flexible to use.It generates dropdown multiselect filter with values available in perticular row. I want to customize this in such a way to pass my own list and values corresponding to same like (list)but not getting how can i do this. If anyone could guide me in this, I will be grateful for you.
{
column_number: 1,
filter_type: "multi_select",
select_type: 'select2',
filter_reset_button_text: false
}]);
You should use the data property
For example
{
column_number: 1,
filter_type: "multi_select",
select_type: 'select2',
filter_reset_button_text: false,
data: ["value1","value2"]
}
Here is small fragment from the docs (you better read more in order to know about yadcf feature)
* data
Required: false
Type: Array (of string or objects)
Description: When the need of predefined data for filter is needed just use an array of strings ["value1","value2"....] (supported in select / multi_select / auto_complete filters) or
array of objects [{value: 'Some Data 1', label: 'One'}, {value: 'Some Data 3', label: 'Three'}] (supported in select / multi_select filters)
Note: that when filter_type is custom_func / multi_select_custom_func this array will populate the custom filter select element

I have a DOM multi-select filter on a single column in a table. The filter is defined with:
yadcf.init(table, [{
column_number: 1,
filter_type: "multi_select",
select_type: 'select2',
select_type_options: {theme: 'bootstrap', width: '250px'},
}]);
When the select is rendered, then it is escaping characters which appear in the table, such as '>', which means that the filtering does not work.
Does anyone know how to fix this?
I want to know if its possible to get the rows with empty fields on this columns. I have a fiddle to explain this.
At first column (Status) I have three values (ON, OFF, (EMPTY)). My problem is to get the rows with empty values (Same row as PR00000003, PR00000005) selecting empty value on the filter.
Thanks in advance.
Since there seems to be some sort of issue with yadcf/select2 and empty string for filtering I can suggest the following solutions:
1) Use regex (see this jsfiddle) -
var oTable = $('#example').DataTable();
yadcf.init(oTable, [
{
column_number: 0,
filter_type: 'multi_select',
append_data_to_table_data: 'before',
data: [ {value:'^$', label:'Empty' }],
filter_match_mode: 'regex',
select_type: 'select2'
}]);
2) Use datatables HTML5 data-* attributes ,
3) Use Chosen plugin (IMO Select2 fits datatables/yadcf better) instead of select2
see jsfiddle sample
var oTable = $('#example').DataTable();
yadcf.init(oTable, [
{
column_number: 0,
filter_type: 'multi_select',
append_data_to_table_data: 'before',
data: [ {value:' ', label:'Empty' }],
filter_match_mode: 'exact',
select_type: 'chosen'
}]);
always bet on yadcf
I need to create a filter on a tipical columns created with images: each field is an image with this format:
<img src='http://lab.onclud.com/psm/blackcircle.png' class='notasg'>
I've created a fiddle example here: fiddle
An explication:
there are only 2 diferents status: [assigned/not assigned] although there are 4 diferents images (black, red, yellow and green).
Only black image correspond to not assigned status. The others three ones (red, yellow and green) correspond to assigned status.
As you could see, I've tried to differentiate those status by class HTML tag in img elements (notasg/asgn).
Thanks in advance.
PD:
I'm getting data from a json, so I can't put:
<td data-search="notassigned">
directly on HTML code. As a solution, I've used createdCell (columnDefs option) as you could see on the next updated to create data-search attribute on td element fiddle.
In this one, as you could test, your previously created filter doesn't work. I've tried some solutions, but no one has worked.
Please help me again on this one. Thanks in advance.
You can make use of the datatables HTML5 data-* attributes, and then tell yadcf to rely on this dt feature with the use of html5_data
So your td will look something like
<td data-search="assigned"><img src='http://lab.onclud.com/psm/redcircle.png' class='asgn'></td>
and yadcf init will look like
var oTable = $('#example').DataTable();
yadcf.init(oTable, [
{
column_number: 0,
html5_data: 'data-search',
filter_match_mode: 'exact',
data: [{
value: 'assigned',
label: 'Assigned'
}, {
value: 'notassigned',
label: 'Not assigned'
}]
}]);
Notice that I used filter_match_mode: 'exact', because I used data-search="notassigned" and data-search="assigned", and since the assigned word included inside notassigned I had to tell yadcf to perform an exact search, this can be avoided if you will use unique search term in your data-search= attribute,
See working jsfiddle
Another solution as introduced by kthorngren from datatables forum is to use the following dt init code
var oTable = $('#example').DataTable({
columnDefs: [{
targets: 0,
render: function(data, type, full, meta) {
if (type === 'filter') {
return full[0].search('asgn') >=1 ? "assigned" : full[0].search('notasg') >= 1 ? "notassigned" : data
} else {
return data
}
}
}],
});
and yadcf init (removed html5_data)
yadcf.init(oTable, [
{
column_number: 0,
filter_match_mode: 'exact',
data: [{
value: 'assigned',
label: 'Assigned'
}, {
value: 'notassigned',
label: 'Not assigned'
}]
}
]);

How can I add custom filter options AND all the other data to a custom function?
Below is my code. I would like to have Yes and No filters, but also filters for all the other values in the column.
{column_number: creator_index,
filter_type: 'custom_func',
custom_func: Creator_Filter_Function,
data: [
{value: 'yes', label: 'Yes'},
{value: 'no', label: 'No'},
],
filter_default_label: "All"
},
You should use the append_data_to_table_data option for your filter
From docs:
append_data_to_table_data
Required: false
Type: string
Default value: undefined
Possible values: before / sorted
Description: Use 'before' to place your data array before the values that yadcf grabs from the table
use 'sorted' to place the data array sorted along with the values that yadcf grabs from the table
Note: 'sorted' option will have affect only if you data is an array of primitives (not objects)
So eventually your code will look like this
{
append_data_to_table_data: 'before',
column_number: creator_index,
filter_type: 'custom_func',
custom_func: Creator_Filter_Function,
data: [
{value: 'yes', label: 'Yes'},
{value: 'no', label: 'No'},
],
filter_default_label: "All"
},
Is there a way to chain filters together where by filters applied in one column will pre-filter the available filters in other columns? Primarily I'm interested in this from a multi_select standpoint, but it could be universal to all filters types I guess.
For example:
Column 1's data contains:
Oklahoma
Missouri
Utah
Texas
Kansas
Column 2's data contains:
Obama
Romney
From the dataset I know that all Column 1 data that has 'Oklahoma' will always mean that Column 2 will equal 'Romney'. Thus, if I select 'Oklahoma' from a mutli_select, then the drop down for the multi_select for Column 2 should now only show 'Romney'.
Basically, can I pre-filter my filters based on other filters already put in place?
I think you are asking about the cumulative_filtering: true option of yadcf,
See the showcase page and here a code sample:
$(document).ready(function () {
'use strict';
var oTable;
oTable = $('#example').DataTable();
yadcf.init(oTable,
[
{
column_number : 0,
filter_type: "multi_select",
select_type: 'select2'
},
{
column_number: 3,
filter_type: "auto_complete",
text_data_delimiter: ","
},
{
column_number : 4,
filter_type: "multi_select",
select_type: 'select2',
column_data_type: "html",
html_data_type: "text",
filter_default_label: "Select tag"
}
],
{
cumulative_filtering: true
}
);
});
As you see the cumulative_filtering: true is an object property, an object that that is a third argument of the init function, when using the .yadcf([{...}]) api you should pass that object as a second arument to the .yadcf constractor, like this:
.yadcf([{...}], {cumulative_filtering: true})
