Call to a member function registerPlugin() on null

Hello. Has anyone got a step-by-step guide to creating a custom BLOCK function ? I am getting an error..

1) SMARTY 3:

2) in my libs/plugins/ directory, I have: block.rblanklines.php

Code:


<?php
/*
 * Smarty plugin
 * -------------------------------------------------------------
 * File:     block.rblanklines.php
 * Type:     block
 * Name:     rblanklines
 * Purpose:  remove blank lines from output
 * -------------------------------------------------------------
 */

function smarty_function_rblanklines($params, &$smarty)
{
 $out="";
 foreach($params as $Fab => $Fac)
 {
  $Fac=trim($Fac);
  if($preg_match("/\w+/",$Fac)){$out.="$Fac\n";}
 }
    return $out;
}


Fac = FUNCTION $ab / Function $ac etc..)

3) in my main PHP file - main2.php I have:-

$smarty->registerPlugin("function","rblanklines","smarty_function_rblanklines");


ERROR MESSAGE: Fatal error: Call to a member function registerPlugin() on null in (path to main2.php)

Choose one. Either registerPlugin, or a properly named file in the appropriate directory.

In regard to your specific issue, that means $smarty variable is not define in the current scope.

Fatal error: Call to undefined function smarty_block_rblanklines() in



https://www.smarty.net/docs/en/plugins.block.functions.tpl

Has anyone got a STEP BY STEP guide as to how to create a custom (block) function ?

1)
Ive got my PHP script & function in the /usr/smarty3/libs/plugins directory.

i assume that's correct ?


2) My tpl file has the opening & closing tags: {rblanklines}

3) My function file has:

Code:


 * File:     block.rblanklines.php
 * Type:     block
 * Name:     rblanklines
 * Purpose:  remove blank lines from output

function smarty_function_rblanklines($params, &$smarty)
{

....  Do stuff..

}





Does that seem OK ? (its not)

Thanks.. Fixed that error.. & discovered another error.. (fixed that myself...)

Though - Ive now got a new problem - I'll fix it after i end work.

Code:
 function smarty_block_rblanklines($params, $content, $smarty, &$repeat)
 


When i run my test script anything between the RBLANKLINES tags (capitals only for emphasis), the content between the tags is just BLANK - no results.

I have added these in my function - One print_r for each variable being received by the function.

Code:

$t=print_r($params);
echo "<pre>PARAMS
$params\n

T=
$t

==================
</pre>";


$params and $content both return a "1" as a result... not the HTML code I expect to be received by smarty...

I'll work on it after

EDIT - Added the 'true' part to the print_r - Getting results

Ive fixed the script.. (see below).

Basically, I create PHP scripts & end up with lots of "white space" between lines of HTML output.

The plugin below basically removes the excess white-space. (I do use the STRIP command for the select/option - But this makes it all one line).

You can see the difference in HTML code here:

http://sudoku.kwister.com/main2.php?file=2020041520 (using the plugin)
http://sudoku.kwister.com/main3.php?file=2020041520 (not using)

Note: the 'file' value is valid for 3 months & will be removed later).

Code:

<?php
/*
 * Smarty plugin
 * -------------------------------------------------------------
 * File:     block.rblanklines.php
 * Type:     block
 * Name:     rblanklines
 * Purpose:  remove blank lines from output
 * -------------------------------------------------------------
 */

function smarty_block_rblanklines($params, $content, $smarty, &$repeat)
{
 $out="";
if(preg_match("/\w+/",$content))
{
$test=explode(PHP_EOL, $content);
 foreach($test as $ab => $ac)
 {
  $ac=trim($ac);
  if(preg_match("/\w+/",$ac)){$out.="$ac\n";}
 }
}
echo $out;
}

?>

You can fix your HTML by passing it through tidy filter.
