 Posted: Tue Feb 24, 2004 1:05 pm Post subject: Refering to a PHP Function with Smarty - Newbie |
 |
|
Hi, I'm new to PHP and Smarty so I'm in need of a little help.
I've made a function with PHP that calls values from the MYSQL database. I have tested the PHP function and it works fine. The next step I've tried to do is integrate the function into one of my Smarty templates. To be honest I haven't got a clue what code I'm supposed to be entering and if I need to assign variables.
This is the PHP code I've written:
| Quote: | function category_desc($id) {
$result = mysql_query("SELECT categoryid, description FROM xcart_categories WHERE categoryid='$id'");
while($row = mysql_fetch_array($result, MYSQL_NUM)){
printf ("$row[1]");
}
mysql_free_result($result);} |
So how do i get this working in smarty templates???
Any help on this would be great |

How about somthing like this:
| Code: |
while($row = mysql_fetch_array($result, MYSQL_NUM)){
$var4smarty[]=$row[1]; // this will populate an array with values
}
$smarty->assign('var4smarty',$var4smarty);
//////////// then in ur template
{if $var4smarty}
<ul>
{foreach from=$var4smarty item=v4s}
<li>{$v4s}</li>
{/foreach}
</ul>
{/if}
|
You can find the functions and constructs i used (there really very simple) in the smarty docs...

| Thanks Nick, that has helped. But in my code the field that is selected in the MYSQL table is determined by the variable $id, how can I state that in smarty so that it displays the correct result? |

Change the code to this, then do some basic PHP learning over at php.net 
| Code: |
while($row = mysql_fetch_array($result, MYSQL_NUM)){
$var4smarty[$row[0]]=$row[1]; // Now u have the id and the val
}
$smarty->assign('var4smarty',$var4smarty);
|
You'll have to look at the foreach() function in the smarty docs on how to access the key as i cant remember off hand....
