Self-adjusting credit card expiration year

August 13th, 2010 · · CakePHP 8 comments - Tags: , ,

Once in a while, it happens, that you need to build a payment form with credit card expiration year as a select input.

With CakePHP’s form helper it’s pretty easy, but what’s even nicer is that you don’t have to hard-code any values for the actual years (and then have to remember to update them as the time goes on).

With the little snippet below we build a select input which starts and defaults to the current year and goes up to seven years ahead.

(So at the time of writing the select input range is: 2010 – 2017)

$this->Form->input('card_expiration_year', array(
                           'type' => 'date',
                           'maxYear' => date('Y', strtotime('+ 7 years')),
                           'minYear' => date('Y'),
                           'dateFormat' => 'Y',
                           'default' => date('Y')));

p.s. Why seven years? (Not sure, just like the number).

A little something about the Form Helper…

Just a quick pointer about the form helper usage…

If you don’t like the default output of $form->input();

echo $form->input('SomeModel.some_field');

//which produces:
<div class="input text">
   <label for="SomeModelSomeField">Some Field</label>
   <input name="data[SomeModel][some_field]" type="text" value="" id="SomeModelSomeField" />
</div>

Mainly the div’s, it produces, you can of course turn them off by using:

echo $form->input('SomeModel.some_field', array('div'=>false));

//which produces:
<label for="SomeModelSomeField">Some Field</label>
<input name="data[SomeModel][some_field]" type="text" value="" id="SomeModelSomeField" />

But you can also specify an alternative wrapper tag:

echo $form->input('SomeModel.some_field', array('div'=>array('tag'=>'li')));

//which produces:
<li class="input text">
   <label for="SomeModelSomeField">Some Field</label>
   <input name="data[SomeModel][some_field]" type="text" value="" id="SomeModelSomeField" />
</li>

P.S I believe it was Mark Story, who’ve pointed this trick out to me. So thank him! ;)
