问题
I have php file called testfun.php. Which is getting values from the databse
<?php
$conn=mysql_connect("localhost","root","") or die("unabke to connect");
$db=mysql_select_db("smartyform",$conn) or die("databse error");
require 'Smarty/libs/Smarty.class.php';
$smarty = new Smarty;
$sel=mysql_query("select * from form");
while($row=mysql_fetch_array($sel))
{
$id=$row[0];
$name=$row[1];
}
$smarty->assign('id',$id);
$smarty->assign('name',$name);
$smarty->display('testfunction.tpl');
?>
I have tpl file called testfunction.tpl. I am getting output in this file
<body>
<ul>
{$id}
:
{$name}
</ul>
</body>
</html>
When I run the testfun.php I got this output:
16 : dg
But I want output like:
1:d
d:g
What should I do ?
回答1:
Store your data in an array. So you have to do a for loop in your tpl.
It would be like this in your tpl:
<ul>
{foreach from=$your_data item=item_value key=key}
<li> { $key } : {$item_value}</li>
{/foreach}
</ul>
In your php make it this way:
require 'Smarty/libs/Smarty.class.php';
$smarty = new Smarty;
$your_row= array();
$sel=mysql_query("select * from form");
while($row=mysql_fetch_array($sel))
{
$your_row[]= $row;
}
$smarty->assign('your_data',$your_row);
$smarty->display('testfunction.tpl');
?>

Hope that helps you.
