Template Variable Issue

Hey guys. Before proceeding, I have read https://vborg.vbsupport.ru/showthread.php?t=228078 and am still not sure what's up with my code.

First, I have this function which is based on a user profile field single select menu.

PHP Code:


		
			
function get_ccode ($countryname) {

    

    $json = file_get_contents('http://country.io/names.json');



    $countries = json_decode($json, true);



    while ($cname = current($countries)) {

        if ($cname == $countryname) {

            return key($countries);

        }

        next($countries);

    }

}

This and other functions are located in a folder on the server. I have added a plugin at the hook "global_bootstrap_init_start" with this code:

PHP Code:


		
			
require(DIR . '/custom/functions.php');

I am now trying to create a code to output a template variable in postbit_legacy. This is the code I have for my plugin which is at the hook "process_templates_complete".

PHP Code:


		
			
$country = $user['field58'];

$ccode = get_ccode($country);

    if ($ccode != null) {

        $imgoutput = "<img src='images/flags/$ccode.png' />&nbsp;&nbsp;";

    }



$templater = vB_Template::create('countrytemplate');

    $templater->register('cimg', $imgoutput);

$templatevalues['ccimg'] = $templater->render();

vB_Template::preRegister('postbit_legacy', $templatevalues);

Then I attempt t use {vb:raw ccimg} in the postbit_legacy template and nothing appears. Where am I going wrong? Thanks in advance.

I think the first thing I'd do is to make sure that $imgoutput is set to something even if get_ccode returns null, just for testing. Maybe something like:

Code:

    if ($ccode != null) { 

        $imgoutput = "<img src='images/flags/$ccode.png' />&nbsp;&nbsp;"; 

    } 

    else {

        $imgoutput = "get_ccode('$country') returned null";

    }

If it's still blank then at least you know that it's something to do with the templates.

I tried your suggestion kh99, still nothing displaying even with the null alert.

What is the content of the template countrytemplate? And have you turned on the option to view templates in the source code and verified it isn't being called?

PHP Code:


		
			
$templater->register('cimg', $imgoutput);

But you say you use {vb:raw ccimg}? Notice the extra c.

Edit: nvm you used

PHP Code:


		
			
$templatevalues['ccimg'] = $templater->render();

although I never used that before.

OK, maybe try

Code:

$templatevalues['ccimg'] = "ccimg";

(you can put it right after the existing line so you don't have to delete anything). And see if that shows anything.

Edit: two more good answers snuck in above mine, but I think we're all thinking along the same lines, which is to find out if your template is rendering like you expect.

It did display "ccimg" after inserting the line kh99 suggested. Also, I am not sure what the content of countrytemplate is. Is it unnecessary to define a new template to add a variable?

Oh, yeah, if you didn't create a template named 'countrytemplate' then that's the problem. You could do this:

PHP Code:


		
			
$country = $user['field58']; 
$ccode = get_ccode($country); 
    if ($ccode != null) { 
        $imgoutput = "<img src='images/flags/$ccode.png' />&nbsp;&nbsp;"; 
    } 

$templatevalues['ccimg'] = $imgoutput; 
vB_Template::preRegister('postbit_legacy', $templatevalues);

or if you want you could create a template called countrytemplate. Maybe it could contain this:

Code:

<img src='images/flags/{vb:raw ccode}.png' />  

and then the plugin would be

PHP Code:


		
			
$country = $user['field58']; 
$ccode = get_ccode($country); 

$templater = vB_Template::create('countrytemplate'); 
    $templater->register('cccode', $ccode); 
$templatevalues['ccimg'] = $templater->render(); 
vB_Template::preRegister('postbit_legacy', $templatevalues);

I don't think it matters much, but some people like to keep all html in templates.

Makes sense. I tried the way you suggested, and it does work. The issue is that country isn't being set. Do I need to do something else to get the field of the person who made the post?

Oh, yeah, I didn't even think about that. Probably what you should do is use hook location postbit_display_complete, and use $post['field58'] (the $post array has the userinfo of the post's author).

Also what you could do if you wanted, instead of preRegistering to postbit_legacy, is to set $post['ccode'], then just use {vb:raw post.ccode}. I guess that's kind of cheating but as long as nothing else is setting a ccode value then it will work.
