在 OpenCart 2.0 中创建自定义字段

Question

我是 OpenCart 的新手，我想知道如何在 OpenCart 后端（在产品部分）添加自定义字段（启用 WYSIWYG 编辑器的文本区域），然后将其回显到前端（@ 987654323@).

我已关注此tutorial 并成功在后端管理面板中创建了自定义字段，但无法将其回显到前端。

Answer 1

您好，我发现这个教程与 Opencart 2.0 兼容：

http://www.php-dev-zone.com/2015/01/how-to-add-custom-product-field-in.html

请不要覆盖核心文件，而是使用 vqmod：

http://www.opencart.com/index.php?route=extension/extension/info&extension_id=19501

我建议您使用教程并将所有内容写入 实际的核心文件首先看看它是否有效（这似乎是正确的）和 然后以正确的方式进行操作并将其全部移至 vqmod。

在：/catalog/controller/product/product.php

您会发现如下内容：

$data['description'] = html_entity_decode($product_info['description'], ENT_QUOTES, 'UTF-8');

如果您在此处添加字段，例如：

$data['custom_desc'] = $product_info['custom_desc'];

然后在前端您将能够将其回显到

/catalog/view/theme/default/template/product/product.tpl

作为

$custom_desc;

open admin\model\catalog\product.php

Find addProducts($data) 
function and add below code just after 
`sort_order`
and before     
date_added = NOW()");
your_desc = '" . $this->db->escape($data['your_desc']) . "',

Now find 
editProduct($product_id, $data)` function and add below code just after sort_order and before date_modified = NOW()
your_desc = '" . $this->db->escape($data['your_desc']) . "',

Now open admin\controller\catalog\product.php
Find getForm() function and add below code:

$data['entry_your_desc'] = $this->language->get('entry_your_desc');

Find below code 
if (isset($this->request->post['isbn'])) {
        $data['isbn'] = $this->request->post['isbn'];
    } elseif (!empty($product_info)) {
        $data['isbn'] = $product_info['isbn'];
    } else {
        $data['isbn'] = '';
    }

and add your code just after it

if (isset($this->request->post['your_desc'])) {
 $data['your_desc'] = $this->request->post['your_desc'];
} elseif (isset($product_info)) {
$data['your_desc'] = $product_info['your_desc'];
} else {
$data['your_desc'] = '';
}

Open catalog\view\theme\default\template\product\product.tpl
and find the below code:

<li><?php echo $text_stock; ?> <?php echo $stock; ?></li>
Now add your code after it:
 <li><?php echo $text_your_desc; ?> <?php echo $your_desc; ?></li>
You can place wherever you want to.

Open catalog\language\english\product\product.php
and add your piece of code:

$_['text_your_desc']               = 'Your_description';

Open catalog\controller\product\product.php
Find:

$data['heading_title'] = $product_info['name'];
and add:

$data['text_your_desc'] = $this->language->get('text_your_desc');

Scroll down and find

$data['product_id'] = (int)$this->request->get['product_id'];

now add:

$data['your_desc'] = $product_info['your_desc'];

Open admin\view\template\catalog\product_form.tpl
Find:

<div class="tab-pane" id="tab-data">

Now add your code:

<div class="form-group">
<label class="col-sm-2 control-label" for="input-your_desc">
<?php echo $entry_your_desc; ?>
</label>
<div class="col-sm-10">
<input type="text" name="your_desc" value="<?php echo $your_desc; ?>"      placeholder="<?php echo $entry_your_desc; ?>" id="input-your_desc" class="form- control" />
</div>
</div>

Open catalog\model\catalog\product.php
Find:

if ($query->num_rows) {
and add your code:

'your_desc'            => $query->row['your_desc'],

Open admin\language\english\catalog\product.php
Find :

//Entry
and add :

$_['entry_your_desc']      = 'Your_description';
