<if> tags

[McBlack]

hello everybody...

I'm trying to make a log in system - and I don't know how to parse if tags correctly.. I've done something temporary but it brings up a lot of bugs.

I want to be able to do something like this

<if="arg">
true
<else>
false
</else>
</if>

anyone know how to do this?

McBlack,

Your If/Else Condition not look like php if/else. Look at the below one.

if(Some Condition){

// If the Condition true execute this block of code
}

else{
//if condition is false execute this block of code
}

Other wise you can do the below one

if(condition){
// Some Code
}
else if(condition){
// Some Code
}
else if(condition){
// Some Code
}
else{
// Some COde
}

for More Information please look at PHP Manual.

Thanks

yes - I know. I guess I should have explained more...

Since I'm making a templating system, I want it to parse the if tags in HTML <if> tags

Sort of like this -

replace <if="(.+?)"> with if( $1 ) {
replace <else /> with } else {
replace </if> with }

Instead of doing that literally, I wanted to make it more like this.

if the argument provided is true, replace the whole if statement with the content provided for if it's true.

if it isn't true, just remove the whole thing altogether - unless there is an else statement. If there is, replace it with the content for else.

THere is no such parsing in HTML. The 'IF' stuff has to be done by JS in the browser or by PHP (or somesuch) on the server.

Unless you are on about this type of PHP parsing:

[b]<?php[/b]
IF ($expression)
 [b]{[/b] 
 [b]?>[/b]
 <strong>This is true.</strong>
 [b]<?php[/b] 
[b]}[/b]
 ELSE
 [b]{[/b] 
 [b]?>[/b]
 <strong>This is false.</strong>
 [b]<?php[/b] 
[b]}[/b]
[b]?>[/b]

Personally, I prefer the alternative syntax for control structures [uk2.php.net] if jumping in/out of PHP/HTML...

<?php if ($expression): ?> 
<strong>This is true.</strong> 
<?php else: ?> 
<strong>This is false.</strong> 
<?php endif; ?>

This is really the same as g1smd's code, just an alternative syntax.

... you guys aren't getting what I'm saying. I know how PHP works, I'm just trying to make it so that I can use that in templates and for it to parse.
