Display data from the database means php smarty mysql - php

Question

help me understand: There is a table in the database:
id f_gdpec w_gdpec url_gdpec p_gdspec
1 Москва Красноярск www.test.ru 450
2 Москва Красноярск www.test.ru 900
3 Москва Красноярск www.test.ru 600
Need to pull data from a database and display means php means smarty. that's what I did: module.php:
<?php
function mod_gdspec($module_id){
$inCore = cmsCore::getInstance();
$inDB = cmsDatabase::getInstance();
$cfg = $inCore->loadModuleConfig($module_id);
$sql = "SELECT f_gdpec,
w_gdpec,
url_gdpec,
p_gdspec
FROM cms_gdspec";
$result = $inDB->query($sql) ;
if ($inDB->num_rows($result)){
$items = array();
while ($item=$inDB->fetch_assoc($result)){
$items[]=$item;
}
}
$smarty = $inCore->initSmarty('modules', 'mod_gdspec.tpl');
$smarty->assign('items', $items);
$smarty->display('mod_gdspec.tpl');
return true;
}
?>
The template mod_gdspec.tpl:
{foreach item=item from=$items}
<div class="mod_latest_entry">
<div class="mod_latest_f_gdpec">
{$item.f_gdpec}
</div>
<div class="mod_latest_w_gdpec" >
{$item.w_gdpec}
</div>
</div>
{/foreach}
data from tabditsy not appear, I can not understand how much.
ask your might. Thank you for your attention.

Answer 1

You are returning the value before assigning the value, remove that unnecessary return value
<?php
function mod_gdspec($module_id){
$inCore = cmsCore::getInstance();
$inDB = cmsDatabase::getInstance();
$cfg = $inCore->loadModuleConfig($module_id);
$sql = "SELECT f_gdpec,
w_gdpec,
url_gdpec,
p_gdspec
FROM cms_gdspec";
$result = $inDB->query($sql) ;
if ($inDB->num_rows($result)){
$items = array();
while ($item=$inDB->fetch_assoc($result)){
$items[]=$item;
}
}
// return true;------------>remove this
$smarty = $inCore->initSmarty('modules', 'mod_gdspec.tpl');
$smarty->assign('items', $items);
$smarty->display('mod_tags.tpl');
return true;
}
?>
