PHP short-hand IF/Else statement

admin — Tue, 12 May 2009 16:30:00 +0000

Let’s keep it simple:

Regular way:

if (statement) {
  $variable = "return this if true";
}
else {
  $variable = "return this if false";
}

Short way:

$variable = (statement) ? "return if true" : "return if false";

And this is how it works: statement ? if-true : if-false

Apache – display server errors on screen

Let’s say that you are developing in PHP and something goes wrong and you end with a blank page instead of the expecting php page… great! what happened, where is the error?

Well, now you have to open the error log and check for the last lines to have a clue of where did you place your fat finger. Wouldn’t be nice if that error was display on your screen, of course it would.

Here is the piece of code that you need to add to your httpd.conf file:

Get the top parent page in WordPress

admin — Wed, 21 Mar 2007 04:38:18 +0000

A couple of days ago I found myself with the issue of getting the top parent of any page (that one which doesn’t have any father), so after look in WordPress documentation I found a nice function called get_page_hierarchy() and also no documentation about it. Without documentation about the function it was going to be a little bit tricky to know wheter or not this was what I was looking for, so I decided create my own function to receive the post_name of the top parent page. As soon I started I realized that my knowledges about recursivity were a little bit rusty, but I got it …

Here is the code:

post_parent == 0){
		return $mypage->post_name;
	}
	else{
		return getTopParentPostName($mypage->post_parent);
	}
