eval template + fetch_template

Hi guys,,

Trying to figure out how precisely vb4 works compared to vb3.
cause not many syntaxes i used to use in *.php appear to be
working on vb4, when fetching and sending data between
teplates and db..

as a exsample, to experiment and learn a little
ive setup a small test product..

Goal : list userid's, username's, emails
Going through each step and makeing my notes ofcourse.

templates and php all set to go, except
im getting a error when i try to eval the data and fetch a template..

Error is fetch_template('$dbtestrow') . '");

PHP Code:


		
			
if ($_REQUEST['do'] == 'main')

{



$emailresult =$vbulletin->db->query_read("SELECT userid, username, email FROM " . TABLE_PREFIX . "user ORDER BY userid");

while ($row = $vbulletin->db->fetch_array($emailresult))

  {

      $userid = htmlspecialchars_uni($row['userid']);

    $username = htmlspecialchars_uni($row['username']);

    $usermail = htmlspecialchars_uni($row['email']);

    

    eval('$dbtestdata("' . fetch_template('$dbtestrow') . '");');

  }



// original print : 

// eval('print_output("' . fetch_template('dbtesttemplate) . '");');



// vb4 template ; may need to be changed.. 

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

 $templater->register_page_templates();

 $templater->register('navbar', $navbar);

 $templater->register('pagetitle', $pagetitle);

 print_output($templater->render());

}

so when i try to run it, i get the error that eval needs to be replaced with vb:template

Error :
Warning: fetch_template() calls should be replaced by the vB_Template class in [path]/includes/functions.php on line

cant find info on vb_template()..

help..

question on vbcom How to upgrade vb3 code

You just need to change it to be like what you did for the template dbtesttemplate - you create it, register variables for it, then render it. Only difference is, you won't do print_output, you'll just assign it to a varialbe:

PHP Code:


		
			
$dbtestdata .= $templater->render();

since im creating an array, would i then need to put the variable register inside the
while loop, or just outside just before it render.. ?

im creating the table rows with the template dbtestrow
template dbtestrow :

Code:

        <tr align="center">

           <td>$userid </td><td>$username</td> <td>$usermail</td>

        </tr>

and i call the eval function from the main template

part of dbtesttemplate :

Code:

<br /><table align="center" border="1">

<tr class="blockhead"><td>Welcome to test database page</td></tr>

<tr></tr><tr></tr>



<!-- get rows -->

$dbtestdata



<!-- close table -->

</table><br />

so my new php would be something like

PHP Code:


		
			
while ($row = $vbulletin->db->fetch_array($emailresult))

  {

      $userid = htmlspecialchars_uni($row['userid']);

    $username = htmlspecialchars_uni($row['username']);

    $usermail = htmlspecialchars_uni($row['email']);

    

  // vb3 :  eval('$dbtestdata("' . fetch_template('$dbtestrow') . '");');

  $dbtestdata = vb_template::create($dbtestrow);



  }

  $dbtestdata->register('userid', $userid);  

  $dbtestdata->register('username', $username);  

  $dbtestdata->register('usermail', $usermail);  

 

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

 $templater->register_page_templates();

 $templater->register('navbar', $navbar);

 $templater->register('pagetitle', $pagetitle);

 print_output($templater->render());

or did i (excuse my expression) fall of the wagon in the last cornor. :rolleyes:

You cannot register multiple variables like that. You need to do it like you did for the other template at the bottom. And,you still forgot the line I told you to add. Oh, and if you are then using that template in your bottom template, you need to register the variable there also.
