So, why does this work: <?php if (condition): ?> <!--html code here--> <?php endif; ?> But not simply this: <?php if (condition) { ?> <!--html code here--> <? } I figured it was just style preference, but I actually can't seem to get it to work the second way. Am I just doing something completely wrong? I can't see the ...

Hi, I am stuck in a Clojure loop and need help to get out. I first want to define a vector (def lawl [1 2 3 4 5]) I do (get lawl 0) And get "1" in return. Now, I want a loop that get each number in the vector, so I do: (loop [i 0] (if (< i (count lawl)) (get lawl i) (recur (inc i)))) In my mind this is supposed...
I am writing some jQuery code that involves jumping from several functions. In one function, an 'if'-statement is used to select where the code will go next. The condition for the if statement is the value of a variable that was passed from the previous function. So, to clarify, a function passes a variable to another function, which the...

Anyways, I've started with this simple php which is suppose to return a number less than 86400 if $temprow1 or 2 are less than 8640...
Ever since reading Clean Code I have been trying to keep my code descriptive and easy to understand. I have a condition where either A or B must be filled in. But not both. And not neither. Currently the if statement to check for this condition is hard to follow at a glance. How would you write the following to make it clear at a gl...
I wish to do something like this: DECLARE @IgnoreNulls = 1; SELECT Col1, Col2 FROM tblSimpleTable IF @IgnoreNulls BEGIN WHERE Col2 IS NOT NULL END ORDER BY Col1 DESC; The idea is to, in a very PHP/ASP.NET-ish kinda way, only filter NULLs if the user wishes to. Is this possible in T-SQL? Or do we need one large IF block like so: IF...
What I want to accomplish is simple. I want a button's text to change depending on what page your on. I start this by using the following: var loc_array = document.location.href.split('/'); Now that I have the url and split it in an array I can grab certain directories depending on the position, like so: if (loc_array[loc_array.leng...
I'm having a very hard time trying to do something very simple. Here's the code: if(data == 'success') { alert('foo'); } else { alert(data); } I've simplified it, but that's all that's necessary to understand what's going on. the variable 'data' is a result of an AJAX call, if that m...
I saw this in code. It blew my mind. <% if (false) { %> <script type="text/javascript" src="~/Scripts/jquery-1.3.2.js"></script> <% } %> This seems so patently illogical that it must be intentional. I can only assume that somehow this "came up", and somebody inserted this as a work-around. There are, of course, no comments. Why ...
I'm stumped on this and my searches aren't turning up anything relevant.. I need to do a while loop that will continue if either of 2 variables are true... as far as I can tell you can't do a "while ($var = '' and $var2 = ''); so I tried this, basically I figured I could just set 2 different if statements so that it would change the vari...

I have statements such as @user = User.find(current_user.id) throughout my app. Sometimes a user might enter with a nil variable (such as a new user for whom current_user is nil). I'm sure the dumb way to do this would be to scatter if statements everywhere like... if current_user.exists? @user = User.find(current_user.id) else re...
Hi whenever i run the code below it occurs to me I have made a mistake using the if exist lines, as no matter whether the directory exists or not, it acts as if the line was never there... either that or its not reading the else line. echo off echo echo (c) Ryan Leach 2010 echo Stockmaster Backup System for exclusive use of Rive...
