Updating records
|
||||
================
|
||||
|
||||
Form
|
||||
----
|
||||
For everything we have done so far, you do not need a plugin at all. Custom records
|
||||
only need :file:`ext_tables.sql` the TCA and TypoScript for rendering.
|
||||
|
||||
Extbase is needed if you provide interaction to the user, e.g. updating or adding
|
||||
records.
|
||||
|
||||
Even that can nowadays achieved using the system extension "Form". Still we will
|
||||
cover how to update a record next.
|
||||
|
||||
We need a form where we can adjust the values of the record, e.g. change the
|
||||
companies name.
|
||||
|
||||
Therefore we will add a new ``editAction()``. This will receive a single ``Address``
|
||||
for editing and provides the form. We also will add an ``updateAction()`` which
|
||||
receives a single ``Address``. This action is the target of the submit form and will
|
||||
update the database record.
|
||||
|
||||
To start editing an address, we will add an link from :file:`index.html` to
|
||||
``editAction()``.
|
||||
|
||||
Link to another action
|
||||
----------------------
|
||||
|
||||
.. admonition:: Task
|
||||
|
||||
Create a link to the ``editAction()`` providing the "current" Address record.
|
||||
|
||||
TYPO3 provides ViewHelpers to create links to different actions. To insert a Link to
|
||||
edit a record, you could use the following:
|
||||
|
||||
.. literalinclude:: ../../CodeExamples/localPackages/example_extension/Resources/Private/Templates/Address/Index.html
|
||||
:language: html
|
||||
:linenos:
|
||||
:dedent: 4
|
||||
:lines: 9
|
||||
|
||||
The ViewHelper generates a link, thanks to the current plugin context, all arguments
|
||||
are prefixed with the plugin namespace.
|
||||
|
||||
Creating Forms
|
||||
--------------
|
||||
|
||||
.. admonition:: Task
|
||||
|
||||
Create a form which will show the current values of a single ``Address`` to the
|
||||
user.
|
||||
|
||||
TYPO3 also provides ViewHelpers to create forms. Of course you could create form with
|
||||
pure HTML, but TYPO3 / Fluid adds some security aspects and makes things easier.
|
||||
|
||||
E.g. a proper validation that forms were not manipulated are added out of the box.
|
||||
Also you do not need to take care of proper names of the inputs to allow Extbase to
|
||||
map incoming inputs.
|
||||
|
||||
A basic form looks like:
|
||||
|
||||
.. code-block:: html
|
||||
:linenos:
|
||||
|
||||
<f:form action="update" object="{address}" name="address">
|
||||
<f:form.textfield property="companyName" />
|
||||
<f:form.submit value="Update" />
|
||||
</f:form>
|
||||
|
||||
Persistence
|
||||
-----------
|
||||
|
||||
.. admonition:: Task
|
||||
|
||||
Save changes to database.
|
||||
|
||||
Once the user submits the form, the ``updateAction()`` method within our controller is
|
||||
called. We therefore have to implement this method and to persist the changes that
|
||||
were submitted.
|
||||
|
||||
We already have an instance of the accordingly repository within our controller. We
|
||||
also receive the modified object as an argument within our action. All we have to do
|
||||
is to update the record within the repository::
|
||||
|
||||
public function updateAction(Address $address)
|
||||
{
|
||||
$this->addressRepository->update($address);
|
||||
}
|
||||
|
||||
At the end of the "request", Extbase will cleanup everything and persist the updates
|
||||
to the backend, which in our case is MySQL.
|
||||
|
||||
Redirect
|
||||
--------
|
||||
|
||||
.. admonition:: Task
|
||||
|
||||
Redirect back to index.
|
||||
|
||||
All our changes are already saved to database, but the user receives an error that no
|
||||
template could be found. We actually do not need any template for our
|
||||
``updateAction()``. Instead we will redirect the user back to the ``indexAction()``.
|
||||
This way he can check whether the change has effected the output and works as
|
||||
expected.
|
||||
|
||||
.. note::
|
||||
|
||||
Following REST, an update returns the updated resource, which is the uri to the
|
||||
resource, in our case the redirect.
|
||||
|
||||
As Browsers do not support ``PATCH``, which would be the request method, we use
|
||||
``POST``, see: https://en.wikipedia.org/wiki/Representational_state_transfer#Relationship_between_URL_and_HTTP_methods
|
||||
|
||||
As we extend ``ActionController`` we can use the following line to redirect to
|
||||
another action::
|
||||
|
||||
$this->redirect('index');
|
||||
|
||||
Cache clearing
|
||||
--------------
|
||||
|
||||
Even if the user is redirected, he does not see any difference. That's due to TYPO3
|
||||
caching.
|
||||
|
||||
.. admonition:: Task
|
||||
|
||||
Make changes visible in index action.
|
||||
|
||||
Extbase, by default, clears the cache for all updated records. Therefore the page
|
||||
cache for the pages holding the records is cleared. As our plugin resists on a
|
||||
different page, we have to configure TYPO3.
|
||||
|
||||
Same is true for plain TYPO3 Backend. As soon as a record is edited, the page cache
|
||||
is cleared. If this record is displayed on another page, the caching has to be
|
||||
configured, so this is not Extbase specific.
|
||||
|
||||
The caching can be configured using Page TS Config:
|
||||
|
||||
.. code-block:: typoscript
|
||||
|
||||
TCEMAIN {
|
||||
clearCacheCmd = 1
|
||||
}
|
||||
|
||||
See: https://docs.typo3.org/typo3cms/TSconfigReference/PageTsconfig/TceMain.html#clearcachecmd
|
||||
|
||||
Flash message
|
||||
-------------
|
||||
|
||||
.. admonition:: Task
|
||||
|
||||
Inform user about what happened.
|
||||
|
||||
We now have a fully working process. Still in a long list of records, the user might
|
||||
not notice a difference. Also if he leaves the computer and comes back, he will not
|
||||
know what was done before.
|
||||
|
||||
Extbase has a feature called "Flashmessages" which are also used within TYPO3
|
||||
Backend. They inform a user on next page about some thing that happened during
|
||||
the last request. We could use that to add a message about which record was updated.
|
||||
This is also just one line within a controller::
|
||||
|
||||
$this->addFlashMessage(
|
||||
$address->getCompanyName() . ' was updated.',
|
||||
'Update successfully'
|
||||
);
|
||||

||||

||||

||||
