Master Zend Framework:
Howto Handle External Form Element Dependencies with FormElementManager
April 22, 2014 @ 11:58:07

The Master Zend Framework site has posted a tutorial wanting to help you understand external form element dependencies with help from FormElementManager.

Zend Framework 2, like all great PHP frameworks, provides thorough infrastructure for creating forms in your application. Whether that's form objects, form elements, fieldsets, validation groups or that they interact with so many other components in the Zend Framework 2 default libraries. But how do you handle external dependencies? [...] So what if you need a custom form element in your application, one which will render a list of articles from a database table? [...] In today's post, we're going to look at how to create such a custom element, extending the existing select element.

He walks you through the steps you'll need to make the custom element and hook it into the FormElementManager for correct use:

  • Create a New Form Element
  • Implement the getFormElementConfig Method
  • Create a New Form Object
  • Instantiate the Form Via the FormElementManager

Code is included for each step of the way so you can ensure you end up with a working example.

Joshua Thijssen:
Dynamic form modification in Symfony2
March 20, 2014 @ 09:42:16

Joshua Thijssen has a new post to his site looking at a way to dynamically modify forms in a Symfony2-based application. Form handling can be a bit tricky (especially with more complex elements), and modifying them on the fly can be even more difficult.

Sometimes (or actually, a lot of the time), handling forms will go beyond the basics. And even though symfony2 gives you out-of-the-box a really clean way of creating forms, it sometimes just isn't enough. Fortunately, you are not alone in writing forms, and many posts exists with information on how to handle complex forms. In this post, I will try and demonstrate how to create a dynamic form where you can select a city based on the chosen province.

His example lets the user pick their province and then populates the other select with cities in that area. He includes the code for the form to create these two selects and how to pull out the list of provinces to populate the first. He goes through each part of the example code explaining the methods, what they're doing and how a pre-submit event can be used to populate the second list.

Zend Framework 2 - The New HTML5 Form Fields - Part 2
July 12, 2013 @ 13:41:56

Matthew Setter has posted the second part of his look at the HTML5 form support that comes with Zend Framework 2. In this new post, he focuses on a few different fields - month, range, color, week and number.

Owing to the overwhelming popularity of the first post on the new HTML5 fields in Zend Framework 2 here on Malt Blue, it's only right to have a follow up, covering the other available elements. [...] To really show just how effective using these new elements is, each code snippet had an accompanying screenshot of the element, rendered in iOS on iPhone.

He includes examples for each of the element types including a small screenshot and the code needed to create it. They show how to create the elements and define the custom attributes (like the range for a "Number" field or the date range for a "Week").

Zend Framework 2 Forms - Simple and Available Everywhere
April 04, 2013 @ 11:29:49

Matt Setter has a new post to his site today about forms in Zend Framework 2 including a full example on how to use them to create a form for user information (first name, last name).

I think it goes without saying, forms are one of the central elements of any web-based application. They're used for everything from logging in, to searching content and managing information. Given that, they should be first-class citizens, able to be developed and reused with relative ease. [...] However, given the amount of options, configurability and flexibility required, this isn't always easy. [...] In today's post, I'm going to assume you have a basic understanding of how forms work now. [...] I'm going to show you how to create flexible, reusable forms in one module and by the power of the ServiceManager reuse them throughout your application.

He starts with the inclusion of a dependency needed for his example - the ZfcUser component (installed via Composer). He then moves on to the actual code for the form creating a reusable module, an entity class for the User and the Fieldset/Form classes for the contents of the form. He also includes the code for the controller action and the view that outputs the form itself and handles the repopulation automagically (and includes a CSRF token).

PHPWomen.org:
Add values to a symfony form in between save() and serialization to the database
October 05, 2012 @ 08:55:12

Kim Rowan has recently posted this helpful hint to the PHPWomen.org site concerning the addition of values between save/serialization in Symfony (1.4) forms.

OK, I have a Comment model and I want to relate Comment objects to several other different model types. So, I need to be able to persist Comment objects in my database that relate to the author of the comment and one of a handful of other tables, for example, a blog post or a licence record, etc.

She includes the contents of her "schema.yml" definition and the code to create and display a basic form. Inside of her "executeCreate", the form's submission is handled and a "processForm" method is called and the overridden "updateObject " is used to inject the new data (a user ID) into the submission.

Symfony Blog:
Form Goodness in Symfony 2.1
July 30, 2012 @ 13:41:26

On the Symfony blog there's a new post from Bernhard Schussek about some of the changes that have happened in the Forms component of the Symfony 2 framework (in version 2.1).

Those of you who already upgraded to Symfony 2.1 Beta probably noticed that the new version comes with many backwards compatibility breaks in the Form component. Many of you probably ask yourselves: Why? The simple answer is that the Form component is one of the most complex components in Symfony at all.

They list out some of the improvements (plus code showing then at work) for changes like:

  • No more bindRequest()
  • Custom field constraints
  • Error mapping fu
  • Collection improvements

Matt Cockayne:
Bootstrapping ZF2 Forms
July 23, 2012 @ 11:07:00

In this recent post to his site, Matt Cockayne shows you how to bootstrap your forms in a Zend Framework 2 application (as defined in a class).

A brand spanking new Forms component has been rolled out with ZF2. The long and the short of this new component meant that I had the opportunity to hand roll a new way of making my forms work with Twitter Bootstrap. So, a little tinkering, a quick pull request to ZF2 to allow the definition of arbitrary options and I came up with some useful View Helpers that can be dropped into a project and used.

He includes the code for the sample class ("MyForm") and highlights the "bootstrap" portions of each element's configuration and walks you through some other handy features of his helpers: auto-rendering forms, a "row" helper and a "collection" helper to help organize the form structure.

Matthew Weier O'Phinney's Blog:
ZF2 Forms in Beta5
July 09, 2012 @ 09:34:05

In this new post to his blog, Matthew Weier O'Phinney about some of the recent updates in the latest beta (beta5) of the Zend Framework 2's "Forms" component.

Forms are a nightmare for web development. They break the concept of separation of concerns: they have a display aspect (the actual HTML form), they have a validation aspect and the two mix, as you need to display validation error messages. On top of that, the submitted data is often directly related to your domain models, causing more issues. [...] Add to this that the validation logic may be re-usable outside of a forms context, and you've got a rather complex problem.

He talks about the newly-rewritten form component along with the new InputFilter to accompany it. He includes an example of using this new component - making a User form that, based off of some annotation rules, does some validation on the property values and things like "required" and custom types. He also talks about some of the other features included in the new package like hydration, complex annotation support and tools to work with collections.

You can download this latest beta release from the packages.zendframework.com site.

Rob Allen's Blog:
Zend Framework 2 beta 4 released
May 28, 2012 @ 19:42:51

As Rob Allen mentions in his latest post, the latest revision of the Zend Framework v2 has been released and is ready for testing - Zend Framework 2 beta4.

Earlier this week, we got beta 4 of Zend Framework 2 out of the door. This version has some very significant improvements in it which mean that if you're following along at home with the betas, then you're going to be doing a bit of updating! Most of the B/C breaks are noted in this thread.

He's also made updates to his Zend Framework 2 tutorial to match these most recent changes. He points out three key new features - the ZendServiceManager, ZendForm and ZendInputFilter updates and the introduction of Composer support to pull packages.

Easy Form Generation Using FuelPHP
March 14, 2012 @ 10:05:17

On the NetTuts.com site today there's a new tutorial from Sahan Lakshitha about creating forms in FuelPHP, the PHP 5.3-centric framework.

Thanks to FuelPHP's fieldset class, working with forms couldn't be easier. With a few lines of code, you can easily generate and validate a form. Today, we're going to learn how to do just that!

He starts with guiding you through a simple install of the FuelPHP framework and configuring it to connect to a MySQL database. He shows how to set up a model, specify its properties and creating a controller to handle the user interaction. Using the definitions in the model, FuelPHP can automatically generate a form, complete with default options and some validation on the field (things like "required", "valid_url" and "max_length"). There's also code included showing how to edit current posts and listing out the complete post list.
