How to call a variable from within the Threadbit template?

[Tamtams]

I'm trying to convert over a vb3 product to vb4, and am running into an issue with the template system. Specifically, I am having trouble passing a variable to be outputted from within the template.

I am using the following code in a plugin which has the hook location of threadbit_display:

PHP Code:

$templater = vB_Template::create('custom_template');
$templater->register('my_var', $my_var);
$templatevalues['custom_template'] = $templater->render();
vB_Template::preRegister('threadbit', $templatevalues); 


Then in the style manager for threadbit, I added the following :
{vb:raw custom_template}

Unfortunately, it didn't work. Also tried {vb:raw custom_template.my_var} and it didn't work.

I've turned on dev mode, and custom_template appears under the list of template usage. It is highlighted in red though - I don't know what that means.

Anyone have any ideas?

PHP Code:

$templater = vB_Template::create('custom_template'); 
$templater->register('my_var', $my_var); 
$custom_template = $templater->render(); 
vB_Template::preRegister('threadbit', array('custom_template' => $custom_template)); 


Now you can use {vb:raw custom_template}

Thanks Lynne - I copied and pasted that code exactly though, and it still didn't work... I changed $my_var to "Test123" just to make sure it was a variable assignment error or anything, but still a no go.

It is ok to be including this code in a plugin which uses hook location threadbit_display, correct?

Do you know if it is your template that isn't rendering or the preregistering that isn't working? Do some debugging in that area to find out (just assign xxx to a variable and preregister is and see if it shows up).

Hi Lynne - That is exactly what I did - I assigned the value "Test123" to the variable, so it looks like it is the pre-registering which isn't working...

For example -

$templater = vB_Template::create('custom_template'); 
$templater->register('my_var', 'Test123'); 
$custom_template = $templater->render(); 
vB_Template::preRegister('threadbit', array('custom_template' => $custom_template));

{vb:raw custom_template} does not display "Test123"

[Lynne]

This works just fine for me, so preregistering is working:

PHP Code:

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

I'm a little mixed up - can I just use these two lines then, and insert whatever variable I want for $custom_template? I.e. is the 4 line version redundant, or do they both versions do the same thing?

[Lynne]

You could just do it with two lines. I thought you had a template you were wanting to use though.

[Tamtams]

Well, I think I should be using templates in order to use the cache system, correct? I.e. if I just use pre-register no caching will occur, right?

--------------- Added [DATE]1262298647[/DATE] at [TIME]1262298647[/TIME] ---------------

Also - just to clarify - i am able to access the variable using the 2 line version, but when I register as a template I am unable to access the variable.

When I turn on debug mode I can confirm the template is being loaded though. There is a (20) beside it, and its name is highlighted in red (which I assume means its not cached?)

[Lynne]

I would guess something is wrong with your template then. Try just putting "hello" in the template and see if you get that to print out.
