Actually a function that i have written called print_r_html that does the necessary replacements of spaces with nbsp's and /n with <br>.

I'm a smarty newb (born just a few days ago) so please take it easy!

I'd just like a nice way to get smarty to print out an array structure. I spent quite some time searching and found lots of threads showing sections and foreach's which work for displaying the table in html tables.

I was about to see how to just call the php function (and found the {php} tags) but then read this is really unadvised. I'm not sure why exactly as long as you restrict your php use to DISPLAY FUNCTIONS only...?

Anyway, could someone give me some advice on how to achieve what I am looking for? I am liking smarty overall!

Much thanks,
Daniel

There are several ways to do this. One way is to just {$var|@print_r} although that might not be the best formatting for HTML.

Here is how I do it. Put this in your plugin directory (modifier.dump.php)

[php:1:484d65147b]<?php

/*
* Smarty plugin
* -------------------------------------------------------------
* Type: modifier
* Name: dump
* Version: 1.0
* Date: July 28, 2004
* Author: Monte Ohrt <monte@ispi.net>
* Purpose: dump the contents of a var
* Input: var to dump
* Example: {$var|@dump}
* -------------------------------------------------------------
*/
function smarty_modifier_dump($var)
{
$_ret = "<PRE>\n";
$_ret .= print_r($var,true);
$_ret .= "</PRE>\n";
return $_ret;
}

/* vim: set expandtab: */

?>[/php:1:484d65147b]

Usage: {$var|@dump}

Be careful to include the "@" symbol so the modifier acts on the array.

Either {debug} (which opens a separate debug console) or the undocumented debug_print_var modifier are useful:

{$foo|@debug_print_var}

But I often prefer:

{$foo|@var_export:true|nl2br}

Hi guys,

What a fantastic board - a reply within about 10 mins!

Just thought I'd give a summary:

I tried them all and ended up using:

<pre>{$var|@print_r}</pre>

This seems a bit easier to understand than some of the other ones:

{$var|@dump}
Here dump is a modifier which just saves you having to add the <pre> tags - a good idea if you are going to be doing a lot of array dumps.

{$var|@debug_print_var}
This gives a different format - the key's are all bolded. Quite a nice effect although the spacing isn't as nice.

{$var|@var_export:true|nl2br}
Actually prefer:
<pre>{$var|@var_export:true}</pre> as it gives slightly better formatting. Not quite as good as print_r though. The ":true" didn't actually seem to do anything...?

I didn't get the {debug} tag to work to pop up a window. The debug modifier file doesn't have an example of use but TFM probably has it documented.

Thanks guys!
Dan

Just to further Monte's comment, it is actually necessary to use "true" if you want to continue the modifier chain, eg:

{$var|@var_export:true|nl2br} would work

but if you do this:
{$var|@var_export|nl2br}

nl2br will not be applied since it will not have recieved any input from var_export.
