Comment on Converting hexadecimal RGB code to decimal with a bookmarklet by T.J. Crowder

T.J. Crowder — Fri, 23 Mar 2012 10:47:28 +0000

Neat! Maybe handle three-character versions as well, and allow repeated use, e.g. (live copy | source):

var hexa, rgb;

hexa = prompt('Enter a hexadecimal RGB code (# optional):');
while (hexa) {
  if (hexa.charAt(0) === '#') {
    hexa = hexa.substring(1);
  }
  if (hexa.length === 3) {
    hexa = hexa.charAt(0) + hexa.charAt(0) +
           hexa.charAt(1) + hexa.charAt(1) +
           hexa.charAt(2) + hexa.charAt(2);
  }
  if (hexa.length !== 6) {
    rgb = "(Invalid, must be 3 or 6 characters.)";
  }
  else {
    rgb = [
      parseInt(hexa.substring(0,2), 16),
      parseInt(hexa.substring(2,4), 16),
      parseInt(hexa.substring(4,6), 16)
    ].join(' ');
  }
      
  hexa = prompt(hexa + ' converts to the RGB below.\n' +
                'Enter another or Cancel to stop',
                rgb);
}

Thanks! I really wish this stuff was in the documentation.

A note for everyone: Please don’t suggest that I add it to the docs myself. These guys have their own funny rules for what should be included and what shouldn’t.

Comment on Absolute positioning in HTML e-mails for Outlook 2007 by Greg Bulmash

Dude, thanks. This worked great. One bit to note for people needing to do this for multiple table cells… use different names AND different z-indexes for each cell’s shapes. I needed to fill 2 cells and did the backgrounds both at -1 with the foregrounds both at 1, the background wouldn’t show on the second cell. When I changed the background to 2 and the foreground to 3 on the second cell, both displayed nicely.

var $parent; ?? You can always call $this->getParent() in components, or even better, you can call $this->getPresenter().

And the whole foreach thing and name composition is unnecessary. You can filter components by type http://pastebin.com/TYr9nUjB

Comment on Testing for unique value during form validation by Petr 'PePa' Pavel

Petr 'PePa' Pavel — Tue, 08 Nov 2011 11:43:47 +0000

True. It can be in any model/class. In my case, I used this validation for more than one model (not visible in the code above) so I placed it in a shared BaseModel.

Thanks for the example of using callback with an instance of some class. If you happen to need an instance anyway, in your component/form factory then you can use it for the callback and get rid of instantiating the object in the method itself ($me = new self).

Why is the `uniqueEmail` method in class BaseModel? I’d like more

->addRule(callback($usersModel, ‘uniqueEmail’), ‘This e-mail is already registered.’);

Comment on Populating a SELECT box with distinct values by philthathril

philthathril — Wed, 25 Aug 2010 20:46:38 +0000

If you don’t care about the ids, just the value, then you can do something like this…

$list = $this->Item->find(‘list’, array(‘fields’=>array(‘Model.field’)));
foreach ($list as $item) {
$items[$item] = true;
}
$this->set(‘something’, array_keys ($items));

This may not be ideal, but it’ll get the job done. Hope this helps!

Comment on Strong random password with a bookmarklet by T.J. Crowder

T.J. Crowder — Tue, 24 Aug 2010 07:13:53 +0000

Works in Chrome, Opera, and Safari (all on Windows). Works in IE7 if you allow the “scripted window”.

Cool! I’m really starting to enjoy bookmarklets.

And Firefox isn’t the only browser. There’s also Chrome. ;-) And Safari, for our iOS friends…
