Hi there!
I'm facing troubles with my application. I need to create a dynamic set of
options (SELECT-OPTION) from a database table. When the user push the
submit button of a form I need to know what options were selected. I Would
like to know this from the controller, not from javascript
Part of code in my controller:
# Get the options from a table (field nombre)
tipos_de_asunto =
db2(db2.tipos_de_asunto).select(orderby=db2.tipos_de_asunto.nombre)
tipos_asuntos_list = [] # I use a list to save the options
# Looping the resulted set of query
for g in tipos_de_asunto:
# I Create checkbox
tipos_asuntos_list += [INPUT(_type="checkbox",
_name="lista_tipos_asunto", _class="checkbox", _value=g.id, )]
# I create the text of the checkbox
tipos_asuntos_list += [" " + g.nombre]
tipos_asuntos_list += [" (" + g.abreviatura + ")"]
tipos_asuntos_list += [BR()]
# I create the form (update form)
form = SQLFORM(db2.auth_user, administrador, submit_button="Aceptar",
deletable=True, showid=False, formstyle='divs', _id='form_administrador')
# I create an variable that contains form elements and the options of a
SELECT (tipos_asuntos_list)
checkboxes_tipos_asunto = DIV(
DIV(
LABEL("Tipos Asunto:",
_for="listado_tipos_asuntos_administradores"),
_class="w2p_fl"
),
DIV(
DIV(tipos_asuntos_list,
_id="listado_tipos_asuntos_administradores"),
_class ="w2p_fw"
),
DIV(_class ="w2p_fc")
)
# I insert the variable checkboxes_tipos_asunto and the content of list
tipos_asuntos_list
form[0].insert(6, checkboxes_tipos_asunto) # 6 is because I insert
other form elements, not shown in this code
if form.validate():
?????
The big question: How I know what options were selected?
I had thought in use the form.elements with the name of the options,
but I get all the options without knowing what were selected:
elementos=form.elements('[name=lista_tipos_asunto]')
for e in elementos:
print e
RESULT OF PRINT:
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="10" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="12" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="9"
/>
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="16" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="15" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="17" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="3"
/>
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="1"
/>
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="4"
/>
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="2"
/>
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="11" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="6"
/>
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="7"
/>
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="13" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="14" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox"
value="18" />
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="8"
/>
<input class="checkbox" name="lista_tipos_asunto" type="checkbox" value="5"
/>
Any help will be appreciated.
Regards.
