Form UDR

The Form UDR is used to create a form that includes other components where you can enter data to be sent to workflow.

Example of a simple form with one TextField and one Button

You can use the following APL code to create a form as shown above:

//Create the Form UDR
Form searchform = udrCreate(Form);
searchform.method = searchform.METHOD_POST;

//Create the textfield to be included in the form.
TextField searchText = udrCreate(TextField);
searchText.id = "search";
//Must include name otherwise the data can not be sent to workflow
searchText.name = "search";
searchText.placeholder = "Filter Results";

//Create the send button
Button searchButton = udrCreate(Button);
searchButton.buttonType = searchButton.SUBMIT;
searchButton.text = "Search";

//Add the components to the form
searchform.components = listCreate(ComponentUDR, searchText, searchButton);

Another example of a form that uses a grid to place the components.

Example of a form using grid

The APL code to produce the above example is this:

// Create text fields
TextField userTextField = udrCreate(TextField);
userTextField.name = "username";
userTextField.label = "Create a username";
TextField aliasTextField = udrCreate(TextField);
aliasTextField.name = "alias";
aliasTextField.label = "Create an alias";

// Create a radio button group
RadioButtonGroup radioButton = udrCreate(RadioButtonGroup);
radioButton.name = "radioButton";
radioButton.label = "Select a color";
// Create a ordered map to control the order of the radio button
radioButton.buttons = mapCreateOrdered(string, string);
mapSet(radioButton.buttons, "Red", "red");
mapSet(radioButton.buttons, "Blue", "blue");
mapSet(radioButton.buttons, "Green", "green");

// Create integer fields
IntegerField portIntegerField = udrCreate(IntegerField);
portIntegerField.label = "Port";
portIntegerField.name = "port";
IntegerField timeoutIntegerField = udrCreate(IntegerField);
timeoutIntegerField.label = "Timeout";
timeoutIntegerField.name = "timeout";

// Create a dropdown
DropDown dropdown = udrCreate(DropDown);
dropdown.name = "dropdown";
dropdown.label = "Dropdown";
dropdown.items = mapCreateOrdered(string, string);
mapSet(dropdown.items, "Select an item", "");
mapSet(dropdown.items, "First Value", "first");
mapSet(dropdown.items, "Second Value", "second");

// Create a button to be used as the submit button in the form
Button formSubmitButton = udrCreate(Button);
formSubmitButton.text = "Submit";
formSubmitButton.buttonType = formSubmitButton.SUBMIT;

// Create a grid to be used in the form
Grid formGrid = udrCreate(Grid);
formGrid.rows = listCreate(GridRow);

// Add the columns to a row, and then insert that row into the formGrid's rows.
// To simplify the creation of columns and rows, they have been moved to helper functions.
listAdd(formGrid.rows, getRow([getColumn(userTextField, 6), getColumn(aliasTextField, 6)]));
listAdd(formGrid.rows, getRow([getColumn(radioButton, 0)]));
listAdd(formGrid.rows, getRow([getColumn(portIntegerField, 6), getColumn(timeoutIntegerField, 6)]));
listAdd(formGrid.rows, getRow([getColumn(dropdown, 0)]));
listAdd(formGrid.rows, getRow([getColumn(formSubmitButton, 0)]));

// Create the form UDR
Form form = udrCreate(Form);
form.method = form.METHOD_POST;
// Add the grid, which was created for the form and holds the components, as a component of the form.
form.components = listCreate(ComponentUDR, formGrid);

// Helper functions for column and row
GridColumn getColumn(ComponentUDR comp, int width){
    GridColumn col = udrCreate(GridColumn);
    if(width > 0){
        col.width = width;
    }
    col.components = listCreate(ComponentUDR, comp);
    return col;
}
GridRow getRow(list<GridColumn> columns){
    GridRow row = udrCreate(GridRow);
    row.columns = listCreate(GridColumn);
    for (GridColumn column: columns) {
        listAdd(row.columns, column);
    }
    return row;
}

The following fields are included in the Form UDR:

Field	Description

Field	Description
action (string)	This field may contain a string that specifies where to send the form data when a form is submitted. Possible values: An absolute URL - points to another web site (like "http://www.example.com/example.htm") A relative URL - points to a url within the web site (like "example")
attributes (map<string,string>)	This field may contain extra attributes to be added.
components (list<ComponentUDR>)	This field may contain a list of child components, the components that will produce the form data. They can be added direct in the list or inside a Grid UDR and then the Grid UDR is added here.
cssClasses (list<string>)	This field may contain a list of extra values added to class attribute. This is typically used to style the component. Please read more on Bootstrap.
encoding (string)	This field may contain may a string for encoding. Some constants is added to help: `URL_ENCODED`, `TEXT_PLAIN`, `MULTIPART` Default is URL_ENCODED.
id (string)	This field may contain the id of the component
method (int)	This field may contain method used to submit the form. Possible values are: `METHOD_GET`, `METHOD_POST`. Default is METHOD_GET.
