zencart的modules下数据库操作templates排版和common首页引用

把这个学会，zencart的数据库操作，以及各种函数的调用基本会了

这个东西非常有用，你需要认真看一下，不要闲代码多。

 

 

如何在数据库中调出自己想要的产品，让它显示在首页。

 

据我本人不科学的理解，在includes/modules/里面见一个  模块文件，该文件是功能文件，也就是含有sql语句，以及执行sql语句的常用函数，这个是“功能文件”

我在这取名叫做  show_products.php

 

<?php

$show_product = 'SELECT p.products_id,p.products_model,p.products_price, p.products_image, ps.specials_new_products_price,pd.products_name,pd.products_description,cd.categories_description,cd.categories_id FROM products p
     LEFT JOIN specials ps ON ps.products_id = p.products_id
     LEFT JOIN products_description pd ON pd.products_id = p.products_id
     LEFT JOIN products_to_categories pc ON pc.products_id = p.products_id
        LEFT JOIN categories_description cd ON cd.categories_id = pc.categories_id order by rand()';
$show_product_handle = $db->Execute($show_product,18);

while (!$show_product_handle->EOF)
{
 $show_product_content[] = array(
       'id'=>$show_product_handle->fields['products_id'],
       'product_name'=>$show_product_handle->fields['products_name'],
    'products_description'=>$show_product_handle->fields['products_description'],
       'product_module'=>$show_product_handle->fields['products_model'],
       'product_price'=>$currencies->display_price(zen_get_products_base_price($show_product_handle->fields['products_id'])),
       'special_price'=>$currencies->display_price(zen_get_products_special_price($show_product_handle->fields['products_id'])),
       'description'=>$show_product_handle->fields['categories_description'],
       'product_image'=>zen_image(DIR_WS_IMAGES . $show_product_handle->fields['products_image'], $show_product_handle->fields['products_name'], IMAGE_PRODUCT_NEW_WIDTH, IMAGE_PRODUCT_NEW_HEIGHT),
       'product_url'=>zen_href_link(FILENAME_PRODUCT_INFO,'cPath='. $show_product_handle->fields['categories_id'] . '&products_id='.$show_product_handle->fields['products_id'])
 );
 $show_product_handle->MoveNext();
 //print_r($show_product_handle);
}
//print_r($show_product_content);

?>

 

 

 

 

东西取出来了，得要按照我们需要的格式排列啊，就需要模板文件，在includes/templates/template_default/templates/建一个tpl_show_products.php的模板文件

 

<?php
include(DIR_WS_MODULES . zen_get_module_directory('show_product.php'));

if(is_array($show_product_content) && !empty($show_product_content))
{
 $outPutHtml .= '<div id="product">';
 $i=0;
 $j=0;
 foreach ($show_product_content as $key => $value)
 {
    $str=$value['products_description'];
    $val=substr($str,0,170)."...";
    $outPutHtml .= '<div id="Box'. $value['id'] .'">';
    $outPutHtml .=     '<div id="BoxT'. $value['id'] .'">';
    $outPutHtml .=         '<h2><a href="' . $value['product_url'] . '">' . $value['product_name'] . '</a></h2>';
    $outPutHtml .=     '</div>';
    $outPutHtml .=     '<div class="desc"><a href="' . $value['product_url'] . '" class="kuang" alt=" '. $value['product_name'] .' "></a></div>';
    $outPutHtml .=     '<div id="BoxD' . $value['id'] . '">';
    $outPutHtml .=     '<h3><span>RRP: ' . $value['product_price'] . '</span> - OUR PRICE:  ' . $value['special_price'] . '</h3>';
    $outPutHtml .=     $val;
    $outPutHtml .=     '</div>';
    $outPutHtml .=     '<div id="BoxB' . $value['id'] . '">';
    $outPutHtml .=        '<a href="' . $value['product_url'] . '"><img src="includes/templates/2/images2/'. $value['id'] .'.gif"></a>';
    $outPutHtml .=     '</div>';
    $outPutHtml .= '</div>';
      // print_r($value);
     
 }
 $outPutHtml .= '</div>';
}

echo $outPutHtml;
//print_r($show_product_content);
?>
<!--
<div id="p_1">
  <div id="p_li">
   <h2><a href="ghd-red-lust-styler-p-252.html">GHD Pink Limited Edition</a></h2>
  </div>
        <a href="ghd-pink-limited-edition-p-255.html" class="kuang" alt="GHD Red Lust Styler"></a>
<div id="text">
<h3><span>RRP: $299.00 AUD</span> - OUR PRICE: $145.99 AUD</h3>

<div id="an">
<a href="ghd-pink-limited-edition-p-255.html"><img src="includes/templates/2/images2/p_an_4.jpg"></a>
</div>

-->

 

 

最后是引用这一块，比如我想在首页的一个DIV里显示这些内容

 

<div class="products">

 

<?php
//display product module
require($template->get_template_dir('tpl_module_show_product.php', DIR_WS_TEMPLATE, $current_page_base, 'templates').'/tpl_module_show_product.php');

?>

 

 

</div>
