如何在smarty中使用{section}打印关联数组？

Question

I want to print an associative array using section but I'm not able to do so.Following is the PHP and Smarty code :

PHP Code :

  $smarty->assign('$all_latest_news',       $grid_data);

In the above code $grid_data is an associative array which is assigned to the smarty template. For your information the array looks like this after printing using print_r($grid_data) :

Array ( [0] => Array ( [news_id] => 1 [news_title] => News Channel URL [news_link] => http://indiatoday.intoday.in/ [news_added_date] => 2013-02-26 ) [1] => Array ( [news_id] => 2 [news_title] => News Paper Web Address [news_link] => http://www.bhaskar.com/ [news_added_date] => 2013-02-25 ) )

Now I want to print this array in smarty template the code snippet for this is as follows :

<table width="100%" align="center" cellpadding="6" cellspacing="1" bgcolor="#FFFFFF">
                <tr align="center" id="tableHeader">
                    <td width="20%" align="left"><b>News Title</b></td>
                    <td width="55%" align="left"><b>News Link</b></td>
                    <td width="15%" align="center"><b>Option</b></td>
                </tr>
                {section name=news loop=$all_latest_news}
                <tr align="center" id="tabledata" bgcolor="{cycle values="#d0e8f4,#96c0d5"}">
                    <td align="left" valign="top">{$all_latest_news[news].news_title}</td>
                    <td align="left" valign="top">{$all_latest_news[news].news_link|truncate:350:" ...":true}</td>

                    <td align="center" valign="top"><a href="manage_latest_news.php?op=edit&news_id={$all_latest_news[news].news_id}">Edit</a>
                    &nbsp;&nbsp;<a href="manage_latest_news.php?op=delete&news_id={$all_latest_news[news].news_id}" onClick="return ConfirmDelete()">Delete</a></td>
                </tr>
                {sectionelse}
                <tr>
                    <td colspan="5" align="center"><b>No News Available</b></td>
                </tr>
                {/section}
</table>

Using this code I'm not able to print the array values to the respective columns. The column headings getting printed properly. After that the {sectionelse} part is executed and the message "No News Available" gets printed.

Actually I want to print the values in array. Can anyone help me out to resolve this issue? Thanks in advance.

Answer 1

When you assign the values to variables in Smarty, you don't want to put '$' symbol. Change your code to,

$smarty->assign('all_latest_news', $grid_data);

Answer 2

Change $smarty->assign('$all_latest_news', $grid_data);

to :

$smarty->assign('all_latest_news', $grid_data);

Use this :

{foreach from=$all_latest_news item=news name=news}
   {$news.news_title}
{/foreach}
