Download the PHP package arkschools/data-input-sheets without Composer

Data Input Sheets

Library that abstracts a custom data origin as the spine of a table, and builds a data sheet using columns defined through a yml configuration file. The library handle the logic of displaying the table and storing the user input values. Each row can be accessed into a new page that will display a table with one row per object column

Instructions

Download using composer

Enable the bundle in the kernel

Create the yml configuration

• extra_column_types is an optional section that allows to extend the library with new column types
• Create one sheet per custom data origin
• Create as many views as required, columns can belong to several views
• Create all the needed columns for the sheet and set the appropriate type of each one

Advanced yml configuration

Sometimes a view has too many columns to be displayed as a table for each spine value, in that case the view can be declared like this

All the columns will be displayed when accessed an individual spine element

It is possible to lock down a column to prevent modifications via configuration, this is useful if there are periods of time when you don't want users to modify some of the columns

Create the spine and its service

This is the most important file and where the spine column data is queried from, we need to create a class that extends from Arkschools\DataInputSheets\Spine and add our logic to load and __construct

Next step is to create a tagged service with our spine, to do so add the tag data_input_sheets.spine that marks the service as a data input sheet spine and the sheet attribute links it with the configured sheet

Update your database schema

Create\reuse controller and views

A basic controller and template are provided but we do recommend to build your own one tailored to your project needs

If you want to use the default one just add the following route configuration

Available column types

integer

• Uses an input html element to capture the data
• Casts the input value into an integer and stores it in the database as an integer

float

• Uses an input html element to capture the data
• Casts the input value into a float and stores it in the database as a float

string

• Uses an input html element to capture the data
• Stores the input value in the database as a string casting empty strings into null values

text

• Uses a textarea html element to capture the data
• Stores the input value in the database as a string casting empty strings into null values

date

• Uses an input html element to capture the data
• Stores the input value in the database as a datetime object casting empty strings or malformed dates into null values
• By default it uses PHP DateTime format d/m/Y H:i and shows to the user the hint DD/MM/YYYY these values can be changed through configuration like this

yes/no

• Uses a select element with options '' => '', Y' => yes and 'N' => no
• Uses '', 'Y' or 'N' values casting them into null or boolean and stores them in the database as empty or boolean

gender

• Uses a select element with options '' => '', 'M' => M and 'F' => F
• Uses '', M' or 'F' values and stores them in the database as a string or null

serviceList

• Requires the usage of the attribute option that contains an array with as first element a service name and as a second element a method name from that service

• A service with the name app.data_input_sheets.car_lists should exists with a method named getCarDesigns that will return and array with the list of allowed values

• Uses a select element with the options from the list adding at the start an empty option
• Stores the selected value in the database as a string casting empty strings as null

->methodName

• methodName can be any string that can be used as a PHP object method name

• Requires that the Spine in the load method stores in the spineObjects property and array of spine objects indexed by the spineId

• Spine objects should have a method named methodName and arguments can be optionally passed to that method through the option attribute

• It is used just to display values, nothing will be stored in the database

Advanced use cases

Out of the box this library allow user to store the data in a table created by the library, but this behaviour can be changed

Data not stored in the default entity manager

A different Entity Manager can be set by adding a parameter to the parameters.yml file

Data stored in library user controlled table

A custom table can be set to store the data input of an specific sheet

Create a table with the same structure as data_input_sheets_cell, in this example is called 'cars', and modify the spine accordingly

From now on that sheet data will be stored in the custom table

Data stored in library user controlled entity

More control can be obtained setting an entity class that will store the data of an specific sheet

Create the desired entity class with as many properties as columns needs the sheet, for this example it would require id, brand, model and description, please take into account the column types when setting the entity property types

Then modify accordingly the spine class

For the previous example this should be the new configuration file content

Create a custom column type

As explained above new column can be added through the configuration parameter extra_column_types

• Extend Column abstract class and implement the abstract methods
• Extend the other methods if required for your implementation
• Add the newly created class using the extra_column_types configuration

Create a custom column type as a service

• The tag data_input_sheets.column marks the service as a data input sheet extra column and the type attribute links it with the newly added column type
• The column class has to extend Arkschools\DataInputSheets\ColumnType\AbstractColumn and add at least the logic for __construct

Filter a spine at view level

A filter can be added on each view to limit the spine elements displayed in that view

In the previous example "Classics" view will just display cars older than 25 years, to make this possible we need to modify the spine class to have a default filter and to use it during load

Filter a spine via user selection

Apart of the filters that can be added at the view level of the configuration file, a custom selector can be added after choosing a view and before showing its content. This selector can be used to narrow further down the spine elements displayed in the view.

As we saw previously a Spine can extend the methods defaultFilter to add a configuration level filter and the load method to make use of it, the idea behind this new filter is to add the user selection filter to this very same place.

To make it possible we need to create a new class that extends Arkschools\DataInputSheets\Selector\AbstractSelector

Then add the selector as a service tagged with data_input_sheets.selector and a type that will be used in the configuration

Next step is to create the Twig template that will display the selector, it should be something like this

And finally modify the sheet configuration file to make use of the new selector
