Posted: Mon Oct 04, 2010 3:52 pm Post subject: Modified plugin: html_table -> html_assoctable

I improved the html_table function to my needs to obtain html_assoctable in which it is possible to use arrays of arrays, and provide the structure of the content of a cell...

to make myself clear:

$DATA = array(
array("id"=>2, "file"=>"two.jpg"),
array("id"=>4, "file"=>"four.jpg")
);

if I assign this table to my smarty element I can then use the following:

{html_assoctable loop=$DATA cols=2 table_attr='border="0" width=70%' structure="file:%file%, id:%id%"}

this will create:
<table ...>
<tr>
<td>file:two.jpg, id:2</td>
<td>file:four.jpg, id:4</td>
</tr>
</table>

I hope I'm clear in my explanations! And I hope this might serve! don't hesitate to give me some comments!

Code:

<?php
/**
* Smarty plugin
* @package Smarty
* @subpackage plugins
*/

/**
* Smarty {html_assoctable} function plugin
*
* Type: function<br>
* Name: html_assoctable<br>
* Date: Oct 04, 2010<br>
* Purpose: make an html table from an array of arrays<br>
* Input:<br>
* - loop = array to loop through
* - cols = number of columns, comma separated list of column names
* or array of column names
* - rows = number of rows
* - table_attr = table attributes
* - th_attr = table heading attributes (arrays are cycled)
* - tr_attr = table row attributes (arrays are cycled)
* - td_attr = table cell attributes (arrays are cycled)
* - trailpad = value to pad trailing cells with
* - caption = text for caption element
* - vdir = vertical direction (default: "down", means top-to-bottom)
* - hdir = horizontal direction (default: "right", means left-to-right)
* - inner = inner loop (default "cols": print $loop line by line,
* $loop will be printed column by column otherwise)
* - structure = structure of cell contents (ex: <img src=%filename%>%title%</img>,
* will use the filename entry and title entry of the array provided)
*
*
* Examples:
* <pre>
* {table loop=$data}
* {table loop=$data cols=4 tr_attr='"bgcolor=red"'}
* {table loop=$data cols="first,second,third" tr_attr=$colors}
* </pre>
