Workflow Select field

Basic select example

• Type is equal to simple.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE workflow-forms PUBLIC "-//OpenKM//DTD Workflow Forms 2.13//EN"
                                "http://www.openkm.com/dtd/workflow-forms-2.13.dtd">
<workflow-forms>
  <workflow-form task="select test">
    <select label="select label" name="select" type="simple">
      <option label="one" value="001" />
      <option label="two" value="002" />
      <option label="three" value="003" />
    </select>
  </workflow-form>
</workflow-forms>

Allow multiple choice

• Type is equal to multiple.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE workflow-forms PUBLIC "-//OpenKM//DTD Workflow Forms 2.13//EN"
                                "http://www.openkm.com/dtd/workflow-forms-2.13.dtd">
<workflow-forms>
  <workflow-form task="select test">
    <select label="select label"  name="select" type="multiple" >
      <option label="one" value="001"  />
      <option label="two" value="002"  />
      <option label="three" value="003"  />
    </select>
  </workflow-form>
</workflow-forms>

Based on SQL query

We can also get these option values using a SQL query. This SQL sentence should be put on the optionsQuery attribute, but the table attribute should be empty (otherwise, this query is a metadata query). Note that the first element returned in every row is the option value, and the second is the option label. 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE workflow-forms PUBLIC "-//OpenKM//DTD Workflow Forms 2.6//EN"
                                "http://www.openkm.com/dtd/workflow-forms-2.6.dtd">
<workflow-forms>
  <workflow-form task="select test">
    <select label="country" name="country" type="simple"
            optionsQuery="select CT_ID, CT_NAME from COUNTRY order by CT_NAME"/>
  </workflow-form>
</workflow-forms>

The table used in this sample is defined as follows:

create table COUNTRY (
  CT_ID varchar(2),
  CT_NAME varchar(32),
  primary key(CT_ID)
);

insert into COUNTRY (CT_ID, CT_NAME) values ('es', 'Spain');
insert into COUNTRY (CT_ID, CT_NAME) values ('pt', 'Portugal');
insert into COUNTRY (CT_ID, CT_NAME) values ('it', 'Italy');

Based on className

To help get a list from external applications or other purposes, you can build your class to retrieve from these systems the option values.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE workflow-forms PUBLIC "-//OpenKM//DTD Workflow Forms 2.6//EN"
                                "http://www.openkm.com/dtd/workflow-forms-2.6.dtd">
<workflow-forms>
  <workflow-form task="select test">
    <select label="select label" name="select" type="simple"
            className="com.openkm.plugin.form.values.OptionSelectUserList" />
  </workflow-form>
</workflow-forms>

Hierarchical relationship

• The field option value of "childrenSelect" has a parent relation with "parentSelect." It's defined by parentElement="parentSelect."
• The option value "benefits" of the field "childrenSelect" has a parent value "directives" from the area "parentSelect".

Tree relationships:

• directives
  • benefits
  • eligibility
  • services
• handbook
  • basic
  • normal
  • advanced

  <workflow-form task="select test">
    <select label="Parent" name="parentSelect" type="simple">
      <option value="directives" label="Directives" />
      <option value="handbook" label="Handbook Paragraphs" />
    </select> 
    <select label="Children" name="childrenSelect" type="simple" parentElement="parentSelect">
      <option value="benefits" label="Benefits" parentValue="directives" />
      <option value="elegibility" label="Eligibility" parentValue="directives" />
      <option value="services" label="Services" parentValue="directives" />
      <option value="basic" label="Basic" parentValue="handbook" />
      <option value="normal" label="Advanced" parentValue="handbook" />
      <option value="advanced" label="Normal" parentValue="handbook" />
    </select>
  </workflow-form>
</workflow-forms>

Hierarchical relationship with SQL

We use a couple of tables to get the information in this case.

create table LOCALIDAD (
  LOC_ID varchar(8),
  LOC_NAME varchar(32),
  primary key (LOC_ID)
);

create table UBICACION (
  UBI_ID varchar(8),
  UBI_LOC varchar(8),
  UBI_NAME varchar(32),
  primary key (UBI_ID)
);

insert into LOCALIDAD (LOC_ID, LOC_NAME) values ('l0', 'Localidad 0');
insert into LOCALIDAD (LOC_ID, LOC_NAME) values ('l1', 'Localidad 1');
insert into LOCALIDAD (LOC_ID, LOC_NAME) values ('l2', 'Localidad 2');


insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u0', 'l0', 'Ubicación 0');
insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u1', 'l0', 'Ubicación 1');
insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u2', 'l0', 'Ubicación 2');
insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u3', 'l1', 'Ubicación 4');
insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u4', 'l1', 'Ubicación 5');
insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u5', 'l1', 'Ubicación 6');
insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u6', 'l2', 'Ubicación 7');
insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u7', 'l2', 'Ubicación 8');
insert into UBICACION (UBI_ID, UBI_LOC, UBI_NAME) values ('u8', 'l2', 'Ubicación 9');

 This is the form definition:
