Hi ,All
I am a novice of smarty, i`ve a problem about using foreach to fetch data from database, can anyone help ~~thanks a lot!!
This is a example :

Database Name:eio
Table Name:customer

cust_id user phone
1 user1 22552211
2 user2 22334455
3 user3 11223344

config.php(define how i connect to database):

//start
$DSN="mssql://root:hi@localhost/eio";
include_once "DB.php";
$mydb=new DB;
$myobj=$mydb->connect($DSN,false);
if($mydb->isError($myobj))
{ echo $myobj;
return;
}
define(SMARTY_DIR,"/web/smarty/");
define(TEMPLATES_DIR,"/web/templates/");
include(SMARTY_DIR."Smarty.class.php");
$smarty = new Smarty;
$smarty->template_dir =SMARTY_DIR."templates/";
$smarty->compile_dir = SMARTY_DIR."templates_c/";
$smarty->config_dir = SMARTY_DIR."configs/";
$smarty->cache_dir = SMARTY_DIR."cache/";
//end

showfile.php:

//start
include_once("config.php");
$sql="select * from customer";
$myres=$myobj->query($sql);
if($myobj->isError($myres))
{ die ($myres->getMessage());
return;
}
while($row=$myres->fetchRow())
{$arr[$i]=array('id'=>$row[0],'name'=>$row[1],'phone=>'$row[2]');
$i++;
}
$smarty->assign('tmp',$arr);
$smarty->display("data.tpl");
//end

data.tpl

//start
{foreach item=content from=$arr}
{$content}
{/foreach}
//end


Question1:why is the result always "Array Array Array" ?
*How can i show the data using Foreach function?

Question2:if i want to show data in table , how can i design my data.tpl file
in correct code?

because my english is pool , so when i study the document of Smarty, a lot of things isn`t understand for me.
so Can anyone help me with a sample code?
thanks a lot!!

$content is the sql result array for each iteration
to access data, you have to do
{$content.index}
i.e. something like
{$content.name}
but this wouldn't work anyway, as your array is named "tmp" (you give it a name when you assign it)
I would suggest this:
Code:

// ...
while ($row = $myres->fetchRow())
{
 $arr[] = $row;
}
$smarty->assign('arr',$arr);
$smarty->display("data.tpl");

and
Code:

{foreach from=$arr item="row"}
 {$row.name}
{/foreach}


displaying your data in a table is easy
consider some approach like the following:
Code:

<table ...>
{foreach from=$arr item="row"}
 <tr>
  <td>{$row.id}</td><td>{$row.name}</td>
 </tr>
{/foreach}
</table>

HI,
I`ve tried those code with approach changes, but it shows the word "Array" only one time if i used {$row}.
if i set "$arr[]=$row" , whether it means $arr[0]=array,$arr[1]=array
or not.....because $row is an object ,not data of array......
and why i use $row.id?i`ve tried it, and it only show one character ,like A or r......(just like seperate with five characters:A,r,r,a,y)
I am so stupid , so can you explain it for me with above example again.
Thanks a lot!!!
