quickie: setting symfony datetime default

Wednesday, January 6th, 2010

Setting the default value for a symfony form field is one of those tasks so simple that it’s impossible to find out how to do it without a good bit of trial and error.  So without further ado, here is how to set a DateTime field’s default value:

$this->widgetSchema['start_time']->setDefault(date("m/d/Y", now()));

updating symfony form values after submitting

Friday, January 1st, 2010

One thing that’s made programming on symfony very aggravating has been dealing with the forms.  Some sections of the forms are not well documented.  The main issue that I have with this at work is that we deal with GPS coordinates and the users enter their coordinates in degree-minute-seconds format but the database saves them in degree-decimal format.

I had googled for a solution to this problem before, but had not found anything to guide me to the answer.  The couple answers I had found were not very clear on getting it to work.  Till I found this.  Following these guidelines I got it to work on a test deployment of symfony.  Code below:

class Blog extends BaseBlog {
 
	/**
	 * Initializes internal state of Blog object.
	 * @see        parent::__construct()
	 */
	public function __construct()
	{
		// Make sure that parent constructor is always invoked, since that
		// is where any default values for this object are set.
		parent::__construct();
	}
	/*
	 * this function overrides the BaseBlog::save function to allow
	 * changes to be made to the object before saving to the database
	 */
	public function save(PropelPDO $con = null)
	{
		$this->setCommentCount('11');
		return parent::save($con);
	}
 
}

Till Next Time

Adding javascript to symfony form field

Tuesday, November 17th, 2009

In the users table at my company’s website there are fields for company, division, region, and location. Since each level of the company organization affects all the lower categories I have to filter out the invalid choices when a higher level choice is selected.

I’ve implemented this on some forms that I’ve created manually on the site but not in any forms that I haven’t heavily modified from the stock symfony creation.  I started googling around to find a solution but could not find a simple explanation of how to do it.  I expected to find at least some information in one of symfony’s otherwise excellent tutorials, but alas, no.

I had a minor epiphany and went digging through the forms API that symfony provides and realized that I should easily be able to do this through the sfWidgetFormPropelChoice method.  The second parameter passed is the html attributes for the form field.  I thought I had seen a form post here that said that I could add javascript code to the html attributes and not have it get converted into html entities.

I tried throwing a simple alert() inside the onchange attribute for my company box and wham! it worked!  So simple.  Code below:

new sfWidgetFormPropelChoice(
	array(
		'model' => 'Company',
		'add_empty' => true
	),
	array(
		'onchange' => "filterBy('company', 'division', this.value, 'sf_guard_user_user_division_id');" .
			"filterBy('company', 'region', this.value, 'sf_guard_user_user_region_id');" .
			"filterBy('company', 'location', this.value, 'sf_guard_user_user_location_id');"
	)
)
