Make array usable in template

I need an array of userids in template "conversation_userinfo". This array is written in a html or php file.

HTML-File: 1,2,3,4....
PHP-File:echo array(1,2,3,4...);

It should be used like:

Code:

<vb:if condition="in_array($conversation['userid'], $arrayofuserids)">...</vb:if>

How can I get and set that array as $arrayofuserids in template "conversation_userinfo" ?

Try this:

Code:

{vb:set arrayofuserids, {vb:php array, 1, 2, 3, 4}}

Hey noypiscripter,

thanks, but this is not, what I ask for. I ask for an example, how to get the array from file into a variable in template. I set a hook:

Code:

ob_start();

include('path/arrayofuserids.php');

$arrayofuserids=ob_get_contents();

ob_end_clean();

Normally, I would expect variable $arrayofuserids is available in template, but is not. Don't know why. May I use the wrong hook (conversation_before_display_controls) ?

You have to register your variable for your template (or register global)

In vB4 you can

PHP Code:


		
			
ob_start();

include('path/arrayofuserids.php');

$arrayofuserids=ob_get_contents();

ob_end_clean();



vB_Template::preRegister('templateUsingYourArray',array('arrayofuserids' => $arrayofuserids));

Is vB5 the same syntax?

Here: https://www.vbulletin.com/docs/html/..._externalfiles they say it is needed on 4+. Logic, 5>4.

I'll try.

EDIT: I get no result. Neither for {vb:raw $arrayofuserids} nor {vb:raw arrayofuserids}

Try {vb:debugvardump $arrayofuserids}

Ok, my mistake. It seems that vB5 doesn't have a plugin/hook system like vB4. The hooks you see are template hooks, you need php hooks.

For my addons I use only api extensions
Simple example:
- create in /forum/core/packages a subdir /testimportarray/api
- create a file arr.php

PHP Code:


		
			
<?php

if (!defined('VB_ENTRY')) {
    die('Access denied.');
}

class TestImportArray_Api_Arr extends vB_Api_Extensions
{
    public $product = 'testimportarray';
    public $developer = 'testdev';
    public $minver = '5.0.0';
    public $maxver = '6.0.0 Alpha 1';
    public $infourl = '';
    public $checkurl = '';
    public $AutoInstall = 1;
    public $title = 'TestImportArray';
    public $version = '1.0.0';

    public $extensionOrder = 5;

    public static function getArray($prevResult)
    {
        return [1,2,3,4];
    }
}

The subdir name /testimportarray has to be the same as in class TestImportArray_Api_Arr and public $product = 'testimportarray';
The subsubdir name /api is repeated in class TestImportArray_Api_Arr
The filename arr.php has to be the same like in class TestImportArray_Api_Arr

Then check in AdminCP/Add-ons & Hooks/Api Extensions and PHP Hooks if your Api is listed without error

Code:

Add-on: testimportarray

TestImportArray  (1.0.0)         TestImportArray_Api_Arr         Ja         5.0.0         6.0.0 Alpha 1         Ja         5

Then you can use the api function getArray in each template

PHP Code:


		
			
{vb:data userIds, arr, getArray}
{vb:debugvardump $userIds}

I'll try that tomorrow. Thank you.

vB4 mod system != vB5 mod system, so that isn't logically always true.

Anyway, follow what @shka suggested which is using API extensions. An alternative is to use frontend controller. Frontend controller functions are also accessible from the template. But using API extensions is cleaner and more elegant.

If you use a new API like ARR, make it your own API and don't extend it.
You could extend API like Page, Node, User... but why your own?!

PHP Code:


		
			
 <?php



if (!defined('VB_ENTRY')) {

    die('Access denied.');

}



class TestImportArray_Api_Arr extends vB_Api

{



    public static function getArray($prevResult)

    {

        return [1,2,3,4];

    }

}

HTML Code:

{vb:data userIds, testimportarray:arr, getArray}

{vb:debugvardump $userIds}

There is a working example-mod here: https://vbulletin.org/forum/showthre...light=skeleton

It works like a charm. Thank you shka! Thank to all!

One problem left. Why I cannot use that array in a condition?

Code:

{vb:data arrayofuserids, arr, getArray}

{vb:debugvardump $arrayofuserids}

Result:

HTML Code:

var_dump: $arrayofuserids



array(4) {

  [0]=>

  string(2) "1

"

  [1]=>

  string(4) "2

"

  [2]=>

  string(2) "3

"

  [3]=>

  string(1) "4"

}

But...

Code:

{vb:data arrayofuserids, arr, getArray}

<vb:if condition="in_array($conversation['userid'], $arrayofuserids)">...</vb:if>

...works not.

Solved. My solution:

PHP Code:


		
			
return "1,2,3,4";

Code:

{vb:data arrayofuserids, arr, getArray}

{vb:set userIds, {vb:php explode, ',', {vb:raw arrayofuserids.0}}}

<vb:if condition="in_array($conversation['userid'], $userIds)">...</vb:if>

Works, but isn't quite elegant. If there is a better way, I would be interested in. I want that array of userids also global. No need, to load on every post.

Ja, voll. Die vB-Templates nerven ganz sch?n. Das dauert noch, bis ich das kann.

Dein Array-Inhalt sind strings. Du ben?tigst aber int.

PHP Code:


		
			
return array(1,2,3,4);

liefert mir

HTML Code:

var_dump: $array



array(3) {

  [0]=>

  int(2)

  [1]=>

  int(3)

  [2]=>

  int(4)

}

und dann funktioniert es.

HTML Code:

<vb:if condition="in_array($user['userid'], $array)">

Yes

<vb:else />

No

</vb:if>

Deine Funktion sollte public function und nicht public static function sein.

Die Vermutung hatte ich auch. Ich lade das Array aber aus einer Datei. Will nicht jedesmal neu aus der DB laden. Bei mir lautet die Zeile also return file('path/file'); wo vorher die userids untereinander standen und jetzt als eine Zeile, durch Kommas getrennt. Diesen ganzen Aufwand k?nnte ich mir sparen, wenn ich die Tabelle in der Foren-DB anlegen w?rde. Da ?berlege ich noch, weil ich Sicherheitsbedenken habe.

shka	12-07-2018 07:00 AM

I think the problem with his first try is - his strings are two chars (with \n ?)

He wrotes

PHP Code:


		
			
array(4) {
  [0]=>
  string(2) "1
"
  [1]=>
  string(4) "2
"
  [2]=>
  string(2) "3
"
  [3]=>
  string(1) "4"
}

String 0..2 are incorrect so in_array results false, only last strinf is of correct length string(1)

Ich glaube nicht, das es sicherer ist die IDs in einer Datei zu "generieren" (woher auch immer) und diese Datei dann in die API einzubinden. Warum sollte ein Datenbankzugriff unsicher sein? Wenn dieser korrekt eingerichtet ist, sollte das definitiv die bessere L?sung sein.
