If-Else loops Help Please

basil

Ok, I am trying to use the nested if-else statements, but still not getting it to work just right. Lets take an example. I have an IF statement and some code to be executed IF the condition is met. But, if the condition is NOT met, I don't want to do the code that follows (i.e., CODE BLOCK A or 😎, rather I want to skip past all the PhP Code and execute some Java script that follows. If I use a exit; statement, it exits the php file completely and the Jave does not execute.

if(condition)
{

....Do this code

}

ELSE (I want to skip past CODE BLOCKs 1 nd 2 and go to the end of the PHP code (Point A) and do the JAVA Script that follows)

{
CODE BLOCK 1

}

{

CODE BLOCK 2

{
POINT A
?>

SOME HTML CODE AFTER MY PHP CODE

thats cuz js executes on the client and php on the server...all php will execute on the server first and then the js on the client when the page is loaded...

if you want the js to fire

add some kind of hidden field on the page and set it to a value, then in the
<body onLoad="somefuntion();"> call the function and make it run...

Ok, but what if , on the IF condition being false, I want to execute CODE block 2, but NOT code block 1? What I need to do begs for a goto, but I know that's a PHP no no, I am trying to learn how to use if-else to do branching as I wnt it to, but so far I am not having any luck. I know how to make the ELSE cause code that immediately follows the IF code, but I need to do conditional branching somehow.

Why not put CODE BLOCK 1 and 2 before the else?

if(condition)
{

....Do this code

CODE BLOCK 1
CODE BLOCK 2

}

ELSE
{
POINT A
}

SOME JS CODE

Whenever you have 3 blocks of code, It might help to use an if / else if statement. This is assuming that you want to check 3 different conditions.

This is also useful for writing good error handling. You can put error handling in the else statement for when something goes wrong.

<pre>

if(condition1)
{
doSomething();
}
else if(condition2)
{
doSomethingElse();
}
else
{
runIfOtherConditionsFail();
}

</pre>

This will

Thanks for all the help. I finally did get it working the way I wanted used If-else statements...the trick is getting the brackets { } in the right place!
