Php 如何在Prestashop中获取所有附件列表

我正在使用自定义模块，该模块应显示最新（已定义的计数）添加的附件。 我在class/Attachment.php中看到这段代码

public static function getAttachments($id_lang, $id_product, $include = true)
{
    return Db::getInstance()->executeS('
        SELECT *
        FROM '._DB_PREFIX_.'attachment a
        LEFT JOIN '._DB_PREFIX_.'attachment_lang al
            ON (a.id_attachment = al.id_attachment AND al.id_lang = '.(int)$id_lang.')
        WHERE a.id_attachment '.($include ? 'IN' : 'NOT IN').' (
            SELECT pa.id_attachment
            FROM '._DB_PREFIX_.'product_attachment pa
            WHERE id_product = '.(int)$id_product.'
        )'
    );
}

到目前为止，我知道我不需要这个$include检查，所以我需要定制静态函数，比如getAllattachments或new class？非常感谢您的任何想法

在模块中，我有这个

public function hookLeftColumn($params)
{
    if (!$this->isCached('blockattachment.tpl', $this->getCacheId()))
    {
        $attachments = Attachment::getAttachments();
        foreach ($attachments as &$attachment)
        {
            $attachment['image'] = $this->context->language->iso_code.'-default';
            if (file_exists(_PS_MANU_IMG_DIR_.$attachment['id_manufacturer'].'-'.ImageType::getFormatedName('medium').'.jpg'))
                $attachment['image'] = $attachment['id_manufacturer'];
        }

        $this->smarty->assign(array(
            'attachments' => $attachments,
            'text_list' => Configuration::get('ATTACHMENT_DISPLAY_TEXT'),
            'text_list_nb' => Configuration::get('ATTACHMENT_DISPLAY_TEXT_NB'),
            'form_list' => Configuration::get('ATTACHMENT_DISPLAY_FORM'),
            'display_link_manufacturer' => Configuration::get('PS_DISPLAY_SUPPLIERS'),
        ));
    }
    return $this->display(__FILE__, 'blockattachment.tpl', $this->getCacheId());
}

而在第三方物流这一个

{if $attachments}
        {if $text_list}
            <ul class="bullet">
                {foreach from=$attachments item=attachment name=attachment_list}
                    {if $smarty.foreach.attachment_list.iteration <= $text_list_nb}
                    <li><a href="{$link->getAttachmentLink($attachment.id_attachment, $attachment.link_rewrite)|escape:'html'}" title="{l s='More about %s' sprintf=[$attachment.name] mod='blockattachment'}">{$attachment.name|escape:'html':'UTF-8'}</a></li>
                    {/if}
                {/foreach}
            </ul>
        {/if}
    {else}
        <p>{l s='No new attachments' mod='blockattachment'}</p>
    {/if}

{if$attachments}
{if$text_list}

{foreach from=$attachments item=附件名称=附件列表}
{if$smarty.foreach.attachment_list.iteration取决于语言，但请尝试以下操作：

public static function getLatestAttachments($id_lang, $n = 5)
{
    return Db::getInstance()->executeS('
        SELECT DISTINCT (a.`id_attachment`), a.`file`,  a.`file_name`, a.`file_size`, al.`name`
        FROM '._DB_PREFIX_.'attachment a
        LEFT JOIN '._DB_PREFIX_.'attachment_lang al
            ON (a.id_attachment = al.id_attachment AND al.id_lang = '.(int)$id_lang.')
        ORDER BY a.`id_attachment` DESC'.
        ($n > 0 ? ' LIMIT '.$n : '')
    );
}

然后，在您的模块中，您不需要获取所有附件：

public function hookLeftColumn($params)
{
    if (!$this->isCached('blockattachment.tpl', $this->getCacheId()))
    {
        $attachments = Attachment::getLatestAttachments($this->context->language->id, Configuration::get('ATTACHMENT_DISPLAY_TEXT_NB'));
        foreach ($attachments as &$attachment)
        {
            $attachment['image'] = $this->context->language->iso_code.'-default';
            if (file_exists(_PS_MANU_IMG_DIR_.$attachment['id_manufacturer'].'-'.ImageType::getFormatedName('medium').'.jpg'))
                $attachment['image'] = $attachment['id_manufacturer'];
        }

        $this->smarty->assign(array(
            'attachments' => $attachments,
            'text_list' => Configuration::get('ATTACHMENT_DISPLAY_TEXT'),
            'form_list' => Configuration::get('ATTACHMENT_DISPLAY_FORM'),
            'display_link_manufacturer' => Configuration::get('PS_DISPLAY_SUPPLIERS'),
        ));
    }
    return $this->display(__FILE__, 'blockattachment.tpl', $this->getCacheId());
}

您的第三方物流：

{if $attachments}
        {if $text_list}
            <ul class="bullet">
                {foreach from=$attachments item=attachment name=attachment_list}
                    <li><a href="{$link->getAttachmentLink($attachment.id_attachment, $attachment.name)|escape:'html'}" title="{l s='More about %s' sprintf=[$attachment.name] mod='blockattachment'}">{$attachment.name|escape:'html':'UTF-8'}</a></li>
                {/foreach}
            </ul>
        {/if}
    {else}
        <p>{l s='No new attachments' mod='blockattachment'}</p>
    {/if}

{if$attachments}
{if$text_list}

{foreach from=$attachments item=附件名称=附件列表}

{/foreach}

{/if}
{else}
{l s='无新附件'mod='blockattachment'}

{/if}

顺便说一句，我认为附件中没有“重写”链接。
您想要最新附件中的多少个附件？并且只需要用户语言或所有语言的附件？嗨！在tpl foreach循环中，模块配置中的变量设置了一个限值（查看确切的block Manufactor）{if$smarty.foreach.attachment_list.iteration谢谢，但出现错误500。公共静态函数getlatestaAttachments（$id_lang，$n=5）转到attachment.php类。其余在模块php和tpl上。我认为查询有问题。我还没有测试。我没有任何附件。你能打开调试模式吗？在你的条件下，if/defines.inc.php更改定义（'PS_MODE_DEV'，false）；定义（'PS_MODE_DEV'，true）；然后发布错误？您还应该将函数放入附件覆盖中。使用类Attachment extends AttachmentCore创建文件/override/classes/Attachment.php，然后粘贴该函数。然后删除/重命名文件cache/class_index.php。最糟糕的是，开发模式不起作用，我看不出问题出在哪里：（如果您检查模块并给我看一些演示，我可以在PP上给您寄几美元。谢谢！！！：）一些调整，几乎完成了！（$n>0？'LIMIT'.$n:''）；应该是（$n>0？'LIMIT'.$n:''）没有结束“；”。到目前为止还不错。现在的主要问题是获取附件链接，因为getAttachmentLink函数在任何地方都不存在
