• How can I change the `invalid` message of doctrine?

  - by roddik

  Hi. I'm using symfony with doctrine and I make a registration form. Email field is declared unique and if I set it to already existing one, I get the message An object with the same "email" already exist.. I use the following validator: $this->validatorSchema['email'] = new sfValidatorEmail(array('required' => true), array('invalid' => 'Does not seem to be a proper email')); How can I change the "already exists" message? Thanks

• Mipmapping issue with textures rendered on to a flat quad (OpenGL)

  - by Mike2012

  I am having what seems to be a mipmapping problem when rendering textures on to a flat quad. At some camera positions the object looks fine, but then at others it gets very fuzzy. Unfortunately I don't really have any good leads on this problem but I thought if I posted some pictures other who have experiences other issue might be able to give me some insight. Normal: Zoomed Out: Rotated: Could anyone give me any clues about what could be going on here?

• Removing "duplicate objects"

  - by keruilin

  Let's say I have an array of objects from the same class, with two attributes of concern here: name and created_at. How do I find objects with the same name (considered dups) in the array, and then delete the duplicate record in the database. The object with the most-recent created_at date, however, is the one that must be deleted.

• How to check for redirects on ajax calls?

  - by acidzombie24

  I was looking at this answer and some other answers http://stackoverflow.com/questions/199099/how-to-manage-a-redirect-request-after-a-jquery-ajax-call/199156#199156 I can not get this to work. i check the XMLHttpRequest object in both success and complete. In both cases when there is a redirect instead of getting a 302 i get a 200 and the html for that page. How do i make it actually report the 3xx redirect instead of skipping ahead and giving me a 200?

  - by stelmate

  I need to get some children elements and loop over them using inline javascript for a onmouseover event. When I try to use this.getElementsByName I'm getting an error that the object does not support this property.

How can I do it?

• Initiatives to namespace PHP core and libraries

  - by James Maroney

  With the introduction of Object-Oriented and Namespacing capabilities in PHP, I am loving the new found cleanliness of PHP code that can be produced.

Are there any initiatives to organize the PHP core and "common" libraries into namespaces and classes?
