我想为我在Prestashop中添加的每个CMS页面添加一个后端图像，就像我们在Wordpress中为帖子/页面添加精选图片一样。
我在prestashop中找不到任何支持此功能的代码/模块。
答案 0 :(得分：6)
这是可能的，但并不简单。以下是将图像上载到CMS页面模块所需执行的步骤。这种方法不是在PrestaShop中实现这一点的最优雅方式，但我希望它可以帮助您前进。
步骤1，更新模型，使其包含图像：
首先将'classes / CMS.php'覆盖为'override / classes / CMS.php'。
class CMS extends CMSCore
{
// add a public field to store the CMS image
public $CMS_IMG;
/**
* @see ObjectModel::$definition
*/
public static $definition = array(
'table' => 'cms',
'primary' => 'id_cms',
'multilang' => true,
'fields' => array(
'id_cms_category' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedInt'),
'position' => array('type' => self::TYPE_INT),
'active' => array('type' => self::TYPE_BOOL),
// Lang fields
'meta_description' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'size' => 255),
'meta_keywords' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'size' => 255),
'meta_title' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isGenericName', 'required' => true, 'size' => 128),
'content' => array('type' => self::TYPE_HTML, 'lang' => true, 'validate' => 'isString', 'size' => 3999999999999),
// add one image per page
'CMS_IMG' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isString', 'size' => 3999999999999), ),
);
}
第2步，实现在后台上传图片所需的代码：
覆盖'override / controllers / admin / AdminCmsController.php'中的'controllers / admin / AdminCmsController.php'
class AdminCmsController extends AdminCmsControllerCore
{
public function renderForm()
{
$this->display = 'edit';
$this->toolbar_btn['save-and-preview'] = array(
'href' => '#',
'desc' => $this->l('Save and preview')
);
$this->initToolbar();
if (!$this->loadObject(true))
return;
$categories = CMSCategory::getCategories($this->context->language->id, false);
$html_categories = CMSCategory::recurseCMSCategory($categories, $categories[0][1], 1, $this->getFieldValue($this->object, 'id_cms_category'), 1);
// Add code to get image url
$image_url = '';
$imgName = $this->getImageValue($this->object);
if($imgName) {
$image = _PS_IMG_DIR_ . 'cms/' . $imgName;
$image_url = ImageManager::thumbnail($image, $this->table.'_'.(int)$this->object->id.'.'.$this->imageType, 350,
$this->imageType, true, true);
}
$this->fields_form = array(
'tinymce' => true,
'legend' => array(
'title' => $this->l('CMS Page'),
'image' => '../img/admin/tab-categories.gif'
),
'input' => array(
// custom template
array(
'type' => 'select_category',
'label' => $this->l('CMS Category'),
'name' => 'id_cms_category',
'options' => array(
'html' => $html_categories,
),
),
array(
'type' => 'text',
'label' => $this->l('Meta title:'),
'name' => 'meta_title',
'id' => 'name', // for copy2friendlyUrl compatibility
'lang' => true,
'required' => true,
'class' => 'copy2friendlyUrl',
'hint' => $this->l('Invalid characters:').' <>;=#{}',
'size' => 50
),
array(
'type' => 'text',
'label' => $this->l('Meta description'),
'name' => 'meta_description',
'lang' => true,
'hint' => $this->l('Invalid characters:').' <>;=#{}',
'size' => 70
),
array(
'type' => 'tags',
'label' => $this->l('Meta keywords'),
'name' => 'meta_keywords',
'lang' => true,
'hint' => $this->l('Invalid characters:').' <>;=#{}',
'size' => 70,
'desc' => $this->l('To add "tags" click in the field, write something, then press "Enter"')
),
array(
'type' => 'text',
'label' => $this->l('Friendly URL'),
'name' => 'link_rewrite',
'required' => true,
'lang' => true,
'hint' => $this->l('Only letters and the minus (-) character are allowed')
),
array(
'type' => 'textarea',
'label' => $this->l('Page content'),
'name' => 'content',
'autoload_rte' => true,
'lang' => true,
'rows' => 5,
'cols' => 40,
'hint' => $this->l('Invalid characters:').' <>;=#{}'
),
/* Add an fileupload component to the form */
array(
'type' => 'file',
'label' => $this->l('Page image'),
'name' => 'CMS_IMG',
'desc' => $this->l('Upload an image for this page'),
'lang' => true,
'display_image' => true,
'image' => $image_url ? $image_url : false,
),
array(
'type' => 'radio',
'label' => $this->l('Displayed:'),
'name' => 'active',
'required' => false,
'class' => 't',
'is_bool' => true,
'values' => array(
array(
'id' => 'active_on',
'value' => 1,
'label' => $this->l('Enabled')
),
array(
'id' => 'active_off',
'value' => 0,
'label' => $this->l('Disabled')
)
),
),
),
'submit' => array(
'title' => $this->l(' Save '),
'class' => 'button'
)
);
if (Shop::isFeatureActive())
{
$this->fields_form['input'][] = array(
'type' => 'shop',
'label' => $this->l('Shop association:'),
'name' => 'checkBoxShopAsso',
);
}
$this->tpl_form_vars = array(
'active' => $this->object->active
);
return AdminControllerCore::renderForm();
}
public function postProcess()
{
$languages = Language::getLanguages(false);
$update_images_values = false;
foreach ($languages as $lang)
{
if (isset($_FILES['CMS_IMG'])
&& isset($_FILES['CMS_IMG']['tmp_name'])
&& !empty($_FILES['CMS_IMG']['tmp_name']))
{
if ($error = ImageManager::validateUpload($_FILES['CMS_IMG'], 4000000))
return $error;
else
{
$ext = substr($_FILES['CMS_IMG']['name'], strrpos($_FILES['CMS_IMG']['name'], '.') + 1);
$file_name = md5($_FILES['CMS_IMG']['name']).'.'.$ext;
if (!move_uploaded_file($_FILES['CMS_IMG']['tmp_name'],
_PS_IMG_DIR_ .'cms'.DIRECTORY_SEPARATOR.$file_name))
return Tools::displayError($this->l('An error occurred while attempting to upload the file.'));
else
{
$values['CMS_IMG'][$lang['id_lang']] = $file_name;
}
}
$update_images_values = true;
$cms = new CMS((int)Tools::getValue('id_cms'));
$cms->CMS_IMG = $file_name;
$cms->update();
}
}
parent::postProcess();
}
public function getImageValue()
{
$db = Db::getInstance();
$sql = 'SELECT CMS_IMG FROM '._DB_PREFIX_.'cms_lang WHERE id_cms = ' . $this->object->id;
return $db->getValue($sql);
}
}
第3步，实施前端代码
覆盖'override / controllers / front / CmsController.php'中的'controllers / front / CmsController.php'
class CmsController extends CmsControllerCore
{
/**
* Assign template vars related to page content
* @see CmsControllerCore::initContent()
*/
public function initContent()
{
if(!empty($this->cms->CMS_IMG)) {
$this->context->smarty->assign('cms_image', _PS_IMG_ . 'cms/' . $this->cms->CMS_IMG);
}
parent::initContent();
}
}
第4步，在模板中使用您的图片
现在你可以，例如在cms.tpl中使用以下代码：
{if $cms_image != ''}
<img src="{$cms_image}">
{/if}

将所有这些添加为单独的答案，因为一些主持人似乎拒绝最简单的修复/更改原始答案为＆＃34; 此编辑偏离帖子的原始意图＆＃34 ;或＆＃34; 此编辑旨在解决帖子的作者＆＃34; ..right。
<小时/>
步骤0，注意需要在SQL表中手动添加新字段（使用SQL或PhpMyAdmin结构编辑）：
ALTER TABLE `ps_cms_lang` ADD `CMS_IMG` TEXT NULL DEFAULT NULL;
步骤1.2，需要删除类缓存文件以使更改生效：
/cache/class_index.php
第4步，在模板中使用您的图片
..
或者更通用的表单（也可用于类别子页面 - 使用CMS_IMG属性（->或.取决于代码）：
{if isset($cms->CMS_IMG) && $cms->CMS_IMG}
<img src="{$img_ps_dir}/cms/{$cms->CMS_IMG}">
{/if}
ALTER TABLE `ps_cms` ADD `CMS_IMG` TEXT NULL DEFAULT NULL;
'CMS_IMG' => array('type' => self::TYPE_STRING, 'lang' => false, ..
'lang' => false,
$sql = 'SELECT CMS_IMG FROM '._DB_PREFIX_.'cms WHERE id_cms = ' . $this->object->id;
+删除postProcess()
postProcess() $cms->update();中使用postProcess()作为添加新页面的触发器异常，因为部分数据=仅设置$_POST['CMS_IMG']值.. 更新的代码：
public function postProcess()
{
if ( (Tools::isSubmit('submitAddcms') || Tools::isSubmit('viewcms'))
&& isset($_FILES['CMS_IMG'])
&& isset($_FILES['CMS_IMG']['tmp_name'])
&& !empty($_FILES['CMS_IMG']['tmp_name']))
{
$id = (int)Tools::getValue('id_cms');
if ($error = ImageManager::validateUpload($_FILES['CMS_IMG'], 4000000))
return $error;
else
{
$ext = substr($_FILES['CMS_IMG']['name'], strrpos($_FILES['CMS_IMG']['name'], '.') + 1);
$file_name = $id .'_cms_'. md5($_FILES['CMS_IMG']['name']).'.'.$ext;
if (!move_uploaded_file($_FILES['CMS_IMG']['tmp_name'],
_PS_IMG_DIR_.'cms'.DIRECTORY_SEPARATOR.$file_name))
return Tools::displayError($this->l('An error occurred while attempting to upload the file.'));
else {
$_POST['CMS_IMG'] = $file_name;
@chmod(_PS_IMG_DIR_.'cms'.DIRECTORY_SEPARATOR.$file_name, 0666);
}
}
}
parent::postProcess();
}
答案 2 :(得分：2)
上述解决方案不符合PrestaShop的理念。
为CMS页面添加特色图像应模仿现有的机制（请参阅类别或供应商徽标的创建/编辑）。
以下是我的解决方案，为PrestaShop 1.6.1.7工作。它将添加一个图像字段，将图像上传到img / cms文件夹并创建所有缩略图。
我还没弄清楚如何删除图片，非常欢迎您评论我的回答。 更新PrestaShop时要小心，可能会更新覆盖文件夹中的文件。
1 /将以下内容添加到 defines.inc.php （第137行之后）：
define('_PS_CMS_IMG_DIR_', _PS_IMG_DIR_.'cms/');
2 /将以下内容添加到 defines_uri.inc.php （第61行之后）：
define('_THEME_CMS_DIR_', _PS_IMG_.'cms/');
3 /将规则添加到 .htaccess 文件：
RewriteRule ^cms/([0-9]+)(\-[\.*_a-zA-Z0-9-]*)(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/cms/$1$2$3.jpg [L]
RewriteRule ^cms/([a-zA-Z_-]+)(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/cms/$1$2.jpg [L]
4 /将 classes / CMS.php 覆盖为覆盖/ classes / CMS.php ：
<?php
class CMS extends CMSCore
{
// Add an id_image attribute to allow further tests in cms.tpl
public $id_image = 'default';
public function __construct($id = null, $id_lang = null, $id_shop = null)
{
parent::__construct($id, $id_lang, $id_shop);
$this->id_image = ($this->id && file_exists(_PS_CMS_IMG_DIR_.(int)$this->id.'.jpg')) ? (int)$this->id : false;
$this->image_dir = _PS_CMS_IMG_DIR_;
}
}
?>
5 /覆盖 classes / ImageType.php 到覆盖/ classes / ImageType.php
向班级添加公共属性：public $cms
附加到$definition=>fields：'cms' => array('type' => self::TYPE_BOOL, 'validate' => 'isBool')
在getByNameNType中，追加到$types var：'cms'
6 /将 classes / Link.php 覆盖为覆盖/ classes / Link.php ：
class Link extends LinkCore
{
public function getCmsImageLink($name, $id_cms, $type = null)
{
if ($this->allow == 1 && $type) {
$uri_path = __PS_BASE_URI__.'cms/'.$id_cms.'-'.$type.'/'.$name.'.jpg';
} else {
$uri_path = _THEME_CAT_DIR_.$id_cms.($type ? '-'.$type : '').'.jpg';
}
return $this->protocol_content.Tools::getMediaServer($uri_path).$uri_path;
}
}
7 /覆盖 controllers / AdminCmsController.php 到覆盖/ controllers / AdminCmsController.php ：
将以下内容附加到__contruct方法，就在parent :: __ construct（）之前：
$this->fieldImageSettings = array(
'name' => 'banner_img',
'dir' => 'cms',
);
将以下内容追加到postProcess方法，紧接在第351行之后（在其中一个elseif块中，查找submitAddcms和submitAddcmsAndPreview上的条件）：
$object = $this->loadObject();
$image_is_posted = $this->postImage($object->id);
if (! $image_is_posted) {
throw new PrestaShopException("image not posted...");
}
在renderForm方法中，以：
开头if (!($obj = $this->loadObject(true))) {
return;
}
$image = _PS_CMS_IMG_DIR_.$obj->id.'.jpg';
$image_url = ImageManager::thumbnail($image, $this->table.'_'.$obj->id.'.'.$this->imageType, 350,
$this->imageType, true, true);
$image_size = file_exists($image) ? filesize($image) / 1000 : false;
if (Validate::isLoadedObject($this->object)) {
$this->display = 'edit';
} else {
$this->display = 'add';
}
并将以下内容附加到属性$this->fields_form，例如在内容字段之后：
array(
'type' => 'file',
'label' => $this->l('Banner image'),
'name' => 'banner_img',
'display_image' => true,
'image' => $image_url ? $image_url : false,
'size' => $image_size,
'hint' => $this->l('Upload a banner image from your computer.')
)
添加和afterImageUpload方法：
afterImageUpload（）后的受保护函数 { $ return = true; $ generate_hight_dpi_images =（bool）Configuration :: get（＆＃39; PS_HIGHT_DPI＆＃39;）;
$object = $this->loadObject(true);
/* Generate image with differents size */
if (($object->id = (int)Tools::getValue('id_cms')) &&
isset($_FILES) && count($_FILES) && file_exists(_PS_CMS_IMG_DIR_.$object->id.'.jpg')) {
$images_types = ImageType::getImagesTypes('cms');
foreach ($images_types as $k => $image_type) {
$file = _PS_CMS_IMG_DIR_.$object->id.'.jpg';
if (!ImageManager::resize($file, _PS_CMS_IMG_DIR_.$object->id.'-'.stripslashes($image_type['name']).'.jpg', (int)$image_type['width'], (int)$image_type['height'])) {
$return = false;
}
if ($generate_hight_dpi_images) {
if (!ImageManager::resize($file, _PS_CMS_IMG_DIR_.$object->id.'-'.stripslashes($image_type['name']).'2x.jpg', (int)$image_type['width']*2, (int)$image_type['height']*2)) {
$return = false;
}
}
}
$current_logo_file = _PS_CMS_IMG_DIR_.'cms_mini_'.$object->id.'_'.$this->context->shop->id.'.jpg';
if (file_exists($current_logo_file)) {
unlink($current_logo_file);
}
}
return $return;
}
8 /覆盖 controllers / admin / AdminImagesController.php 到覆盖/ controllers / admin / AdminImagesController.php
在__construct方法中，附加到$ this-＆gt; fields_list：'cms' => array('title' => $this->l('CMS'), 'align' => 'center', 'type' => 'bool', 'callback' => 'printEntityActiveIcon', 'orderby' => false)
在__contruct方法中，附加到$this->fields_form=>input：
array(
'type' => 'switch',
'label' => $this->l('Pages CMS'),
'name' => 'cms',
'required' => false,
'is_bool' => true,
'hint' => $this->l('This type will be used for CMS banner images.'),
'values' => array(
array(
'id' => 'cms_on',
'value' => 1,
'label' => $this->l('Enabled')
),
array(
'id' => 'cms_off',
'value' => 0,
'label' => $this->l('Disabled')
),
)
),
在initRegenerate方法中，附加到$types var：'cms' => $this->l('CMS pages')
在_regenerateThumbnails方法中，附加到$process数组：array('type' => 'cms', 'dir' => _PS_CMS_IMG_DIR_)
9 /使用以下内容更新您的CMS页面模板 cms.tpl ：
<!-- Check out the default theme's category_header.tpl for original PrestaShop code -->
<div class="cms_banner"{if $cms->id_image} style="background:url({$link->getCmsImageLink($cms->link_rewrite, $cms->id_image, 'large')|escape:'html':'UTF-8'}) right center no-repeat; background-size:cover; "{/if}>
<div class="container">
<!-- Your content here -->
</div>
</div>

为防止在更新数据时图像松动。 （这是1.7的补充），我建议对postProcess方法进行以下改进：
public function postProcess()
{
$languages = Language::getLanguages(false);
$update_images_values = false;
$cms = new CMS((int)Tools::getValue('id_cms'));
foreach ($languages as $lang)
{
if (isset($_FILES['CMS_IMG'])
&& isset($_FILES['CMS_IMG']['tmp_name'])
&& !empty($_FILES['CMS_IMG']['tmp_name']))
{
if ($error = ImageManager::validateUpload($_FILES['CMS_IMG'], 4000000))
return $error;
else
{
$ext = substr($_FILES['CMS_IMG']['name'], strrpos($_FILES['CMS_IMG']['name'], '.') + 1);
$file_name = md5($_FILES['CMS_IMG']['name']).'.'.$ext;
if (!move_uploaded_file($_FILES['CMS_IMG']['tmp_name'],
_PS_IMG_DIR_ .'cms'.DIRECTORY_SEPARATOR.$file_name))
return Tools::displayError($this->l('An error occurred while attempting to upload the file.'));
else
{
$values['CMS_IMG'][$lang['id_lang']] = $file_name;
}
}
$update_images_values = true;
$cms->CMS_IMG = $file_name;
$cms->update();
}
else
{
$_POST['CMS_IMG'] = $cms->CMS_IMG;
}
}
self::saveProducts();
parent::postProcess();
}
这会在原始条件上增加一个条件
答案 4 :(得分：0)
// add one image per page
'CMS_IMG' => array('type' => self::TYPE_STRING, 'lang' => true, 'validate' => 'isString', 'size' => 3999999999999), ),
Above argument can not create a field on cms_lang table.
So system can gives the following error
Unknown column 'cms_image' in 'field list'
if ($webservice_call && $errno) {
$dbg = debug_backtrace();
WebserviceRequest::getInstance()->setError(500, '[SQL Error] '.$this->getMsgError().'. From '.(isset($dbg[3]['class']) ? $dbg[3]['class'] : '').'->'.$dbg[3]['function'].'() Query was : '.$sql, 97);
} elseif (_PS_DEBUG_SQL_ && $errno && !defined('PS_INSTALLATION_IN_PROGRESS')) {
if ($sql) {
throw new PrestaShopDatabaseException($this->getMsgError().'<br /><br /><pre>'.$sql.'</pre>');
}
throw new PrestaShopDatabaseException($this->getMsgError());
}
}
