[How-To]Use conditionals in vBulletin

Ziki · February 7th, 2007, 12:49 AM

One of the most basic tutorials but I haven't seen it here

So let's start off.Let's say you have an option called Enable hack that is an yesno code.So yes equals 1 and no equals 0.Then you have many options like free,textarea and many more.But this is just basic

Now to the ifs.The if syntax looks like this:

Code:

if ($condition == $somthing)
{
//execute
}

So $condition is something we want to check for.In our case the vbulletin options condition is

Code:

$vbulletin->options['youroptionname']

where youroptionname is the var name you specified for your option.Now we want to check if the hack is enabled and if yes it will execute the code.Yes equals 1 remember?So the hack is set to yes.

Code:

if ($vbulletin->options['optionname'] == '1')
{
//execute
}

The == is to compare.You can also use other comparing signs like > or <.

Now to the else

Lemme say we got one if conditions

Code:

if ($vbulletin->options['optionname'] == '1')
{
code 1
}
else
{
code 2
}

So if the option equals 1, code 1 will be executed but if the option is everything else than 1, code 2 will be executed.

Elseif is the a hybrid.It combines the else and if statements:

So it starts with an if then follows an elseif statement that allows you to use an condition:

Code:

if ($vbulletin->options['optionname'] == '1')
{
code 1
}
elseif ($vbulletin->options['optionname'] == '2')
{
code 2
}
else
{
code 3
}

So if option is 1,code 1 will be executed,if option is 2 then code 2 will be executed and if it is everything else than that, code 3 will be executed.

Now IMPORTANT:

This has to start with an if condition and end with an else or elseif.It can't end with else and after elseif.

Hope you understood that.

If can I ask..
Wich is the best way..

Code:

if ($vbulletin->options['optionname'] == '1') 
{ 
code 1 
} 
elseif ($vbulletin->options['optionname'] == '2') 
{ 
code 2 
}

Or..

Code:

if ($vbulletin->options['optionname'] == '1') 
{ 
code 1 
} 
if ($vbulletin->options['optionname'] == '2') 
{ 
code 2 
}

?

It's the same?

It's the same but it's better to use elseif.Or use the switch function
