Smarty 3.1.8 in the registration function Registerplugin use problem

Have encountered such a problem in learning Smarty
In the php file I wrote this

Function Demo ($params) {        extract ($params);        echo $a. $b;    }    $tpl->registerplugin (' Block ', ' demo ', ' demo ');

Then write this in the template file:

        <{demo a=1 b=text}>        <{/demo}>    

How to Output two x 1text 1text


To solve!

Reply to discussion (solution)

Remove this "<{/demo}>"?

If you get rid of it, there will be an error.

Wood has written plugins, is this example helpful?

I saw that.
That's exactly what I wrote.

Oh, I'll try.

Smarty 3.1.7 Example No problem

$smarty = new Smarty; $smarty->registerplugin ("function", "Demo", "Demotest");; /development type, here is the function call, specify the template function name and PHP function name function demotest ($params) {extract ($params);//Get the parameters A and B echo $a. $b;//Output}

{Demo a= "2" b= "Test"}

$smarty->registerplugin ("function", "Demo", "Demotest")

Yes, no problem.

I'm talking about it.

$smarty->registerplugin ("Block", "demo", "Demotest")

Try again.

The problem is still unresolved.

You look at the example in the manual

function Declarationfunction do_translation ($params, $content, $smarty, & $repeat, $template) {  if (isset ($ Content) {    $lang = $params ["Lang"];    Do some translation with $content    return $translation;  }} Register with Smarty$smarty->registerplugin ("block", "translate", "do_translation");

{Translate lang= "BR"} Hello, world!. {/translate}

The problem is still unresolved.

The block's plug-in is estimated to be called two times

Example I saw an example or an error occurred

Example I saw an example or an error occurred

Block mode will be executed two times. Through if (Isset ($content)) {, made a judgment so only once.

3q problem solved!!

Block will appear two times, the Smarty is a bug it. But does not affect the use.

function Test2 ($arr, $content) {print_r ($arr);//$html = "". $content. ""; /return $html;} $smarty->registerplugin ("block", "Test2", "test2");

<{test2 size= "color=" #ff0000 "}>hello world<{/test2}>

Output:
Array ([size] = [color] + #ff0000) array ([size] = [color] = + #ff0000)
