使用Smarty在tpl中调用的php查询

Question

Im n00b, so basically i want to call my query which is located in my index.php file from my .tpl file using smarty:

Index.php

<?php

//Database connection
$db = mysqli_connect('xx','xx','','xx')
or die('Error connecting to MySQL server.');

//access Smarty template engine
require_once('Smarty-3.1.30/libs/Smarty.class.php');

$smarty = new Smarty();
$smarty->template_dir = 'views';
$smarty->compile_dir = 'tmp';


//query product page
$query = "SELECT * FROM cs_shop";
mysqli_query($db, $query) or die('Error querying database.');

$result = mysqli_query($db, $query);
$row = mysqli_fetch_array($result);


//query
while ($row = mysqli_fetch_array($result)) {
$row['product_category'] . ' ' . $row['product_price'] . ': ' . 
$row['product_quantity'] . ' ' . $row['product_about'] .' ' 
.$row['product_color'] .'<br />';
    }

//db collect data
$smarty->assign('row', $row); 
//template
$smarty->display('index.tpl');

mysqli_close($db);
?>

The while loop i use in the index.php is what i want to call in my .tpl file, im new to smarty and cant get it to work , test database connection and it worked, my , Smarty gets called no errors.

Its a basic static page im just doing experiment, using Smarty, So i just want to display the query as list no td's or anything like that.

So can someone give me a example how my .tpl file would look located in my 'views' directory if i want to display the query?

Thanks in advance

Answer 1

A short example how to display a few words from an array as options within a <p> tag:

index.php

$rows = ['hello', 'there', 'this', 'is', 'me'];
$smarty->assign('rows', $rows);
$smarty->display('index.tpl');

index.tpl

// head, css etc, doesn't matter here

<p>
  {foreach from=$rows item="item"}
    {$item}<br>
  {/foreach}
</p>

This will produce some code which evaluates to:

<p>
  hello<br>
  there<br>
  this<br>
  is<br>
  me<br>
</p>

And as interpreted HTML:

hello
there
this
is
me

As the content of the variables you can pass (almost) whatever you want.

Got this to work, here is what i did.

In my index.php (showing only what i know is not-correct and correct now)

<?php
$new = ['product_category','product_price','product_quantity','product_about','product_color'];

//added an array - rows
$rows = array();

//while loop calling array adding products columns to it
while ($row = mysqli_fetch_array($result)) {
 $rows[] = array(
    'product_category' => $row['product_category'],
    'product_price' => $row['product_price'],
    'product_quantity' => $row['product_quantity'],
    'product_about' => $row['product_about'],
    'product_color' => $row['product_color']
);
}

//db collect data - calls rows
$smarty->assign('row', $rows); 
//template
$smarty->display('index.tpl');

index.tpl

 <p>
  {foreach from=$row item="item"} 

     {$item['product_category'] }<br />

  {/foreach}
 </p>

like i said im totally noob in this, but got it to display. Thanks @Tobias .F
