[Forum] How can I use a raw variable in an if statement?

[Andy]

I preregistered a variable and I would like to use it in an if statement in a template. For example:

<vb:if condition="{vb:raw $my_preregistered_variable}">

content

</vb:if>

What is the correct way of doing this?

[Mark.B]

<vb:if condition="$my_preregistered_variable">

content

</vb:if>

[reefland]

If it's properly registered why not just output the contents in the template? I guess my question is, why the conditional?

[Andy]

<vb:if condition="$my_preregistered_variable">

content

</vb:if>

Hi Mark,

That doesn't work. Preregistered variable have to be in the form of: {vb:raw $my_preregistered_variable}

If it's properly registered why not just output the contents in the template? I guess my question is, why the conditional?

When a member has is on another members Ignore List, currently threads are show when viewing the forums. I would like to put a conditional around the threadbit template so that it's not displayed if the thread is started by a member that is on another members Ignore List.

{vb:raw $variable} is correct. If you use it in a conditional, then it needs to meet some condition even if it is != "".

Mark.B is correct, if you use it in a conditional it would be $my_preregistered_variable. You can use it without and comparison operator because it will be converted to a boolean based on a set of rules (see the php docs, http://us2.php.net/manual/en/languag...oolean.casting).

To insert the value other places in the template it would be {vb:raw my_preregistered_variable} (no $).

[reefland]

You are right, it is {vb:raw variable}.

[Andy]

The preregistered variable in my case is equal to the following:

$thread['postuserid'] <> '7460'

This works just fine to exclude threadid 7460 when viewing the forum it is in.

<vb:if condition="$thread['postuserid'] <> '7460'">

threadbit template

</vb:if>

However none of the following work.

<vb:if condition="{vb:raw $my_preregistered_variable}">

threadbit template

</vb:if>

<vb:if condition="$my_preregistered_variable">

threadbit template

</vb:if>

Hi KLH,

If I try it without the $ sign, I get the following error:

Warning: Invalid argument supplied for foreach() in [path]/includes/functions.php on line 3459

What does the code look like where you registered it?

What does the code look like where you registered it?

I preregister the variable using a plugin which calls a php script.

I can insert the preregistered variable in the first line of the threadbit template like this:

{vb:raw $my_preregistered_variable}
threabit template

This will echo the following many times as that threadbit is called many times when displaying a forum.

$thread['postuserid'] <> '7460'

I don't understand - are you just telling me it works with the '$'? OK, can't argue with the fact that it works for you. I just wondered what your preRegister line looks like because I've always seen it work without the dollar sign.

[Andy]

My plugin PHP code looks like this

ob_start();
include('/path/to/my/script.php');
$my_preregistered_variable = ob_get_contents();
ob_end_clean();

vB_Template::preRegister('threadbit',array('my_preregistered_variable' => $my_preregistered_variable));

It appears there's no way to use a preregistered variable in an if statement.
