如何将 jquery ui 滑块添加到 PrestaShop 模块表单

Question

我想在我的 PrestaShop 模块的配置页面上添加一个范围滑块。我尝试使用 HelperForm class 来做到这一点，但我无法做到这一点，如果我写其他类型，例如 'textarea' 或 'checkbox'，它工作正常，即使不是真正的标准输入类型，例如 'color'，但 'range' 不起作用

<?php
if (!defined('_PS_VERSION_'))
    exit;

class icropper extends Module
{
    public function __construct()
    {
        $this->name = 'icropper';
        $this->tab = 'front_office_features';
        $this->version = '1.0';
        $this->author = 'AppDev';
        $this->need_instance = 1;
        $this->ps_versions_compliancy = array('min' => '1.5', 'max' => _PS_VERSION_);

        parent::__construct();

        $this->displayName = $this->l('icropper');
        $this->description = $this->l('Module for Cropping Images');

        $this->confirmUninstall = $this->l('Are you sure you want to uninstall?');

        if (!Configuration::get('MYMODULE_NAME'))
            $this->warning = $this->l('No name provided');
    }

    public function install()
    {
        $filename = _PS_ROOT_DIR_.'/override/cropp.php';
        $ext = get_loaded_extensions();
        foreach($ext as $i)
        {
            if($i == "imagick") {
                $imgck = $i;
                break;
            }
        }
        if (!parent::install()) {
            return false;
        } elseif (!$imgck) {
            $this->context->controller->errors[] = $this->l('In your server does not installed Imagick library');
            return false;
        } elseif(file_exists($filename)) {
            $this->context->controller->errors[] = $this->l('File that override cropping 
            already exist, please delete it and replace file by yourself');
            return false;
        }else {
            //copy(__DIR__ . '/override/list_footer.tpl', _PS_ROOT_DIR_ . '/override/helpers/admin/templates/list');
        return true;
        }

    }

    public function uninstall()
    {
        if (!parent::uninstall())
            return false;
        return true;
    }

    public function getContent()
    {
        return $this->DisplayForm();
    }

    public function displayForm(){
        $fields_formm[0] = array(
            'form' => array(
                'legend' => array(
                    'title' => $this->l('Header'),
                    'icon' => 'icon-file-text'
                ),
                'input' => array(
                    array(
                        'type' => '',
                        'name'=> 'vania',
                        'min'=>0,
                        'max'=>100,
                        'step'=>1
                    ),
                    'submit' => array(
                        'title' => $this->l('Generate')
                    )

                )
            )
        );

        $helper = new HelperForm();
        $helper->show_toolbar = false;
        $helper->table = $this->table;
        $lang = new Language((int)Configuration::get('PS_LANG_DEFAULT'));
        $helper->default_form_language = 1;


        $this->fields_formm = array();
        $helper->submit_action = 'submitform';
        return $helper->generateForm(array($fields_formm[0]));
    }
}
?>

Answer 1

您必须扩展辅助表单的视图。我会努力 guide 你 :).

首先，你的模块必须挂在这个钩子上 'displayBackOfficeHeader':

public function install(){
    [...]
    $this->registerHook('backOfficeHeader');
    [...]
}

因此编辑您的代码以添加这行代码。

第二步，为hook添加函数，为slider加载、查询和jqueryui

public function hookBackOfficeHeader($params){
    if ( Tools::getValue('module_name') == $this->name OR Tools::getValue('configure') == $this->name ) {
        $this->context->controller->addJquery();
        $this->context->controller->addJqueryUI('ui.slider');
    }
}

第三步，在 fields_form 数组中的输入中添加一个 'new' 类型，例如 rangeslider，我建议您使用以下更正的代码行：

public function displayForm(){
    $fields_form = array(
        'form' => array(
            'legend' => array(
                'title' => $this->l('Header'),
                'icon' => 'icon-file-text'
            ),
            'input' => array(
                array(
                    'type' => 'rangeslider',
                    'name'=> 'vania',
                    'label' => $this->l('Select range'),
                    'min'=>0,
                    'max'=>100,
                    'step'=>1
                ),
            ),
            'submit' => array(
                'title' => $this->l('Generate')
            )
        )
    );

    $helper = new HelperForm();
    $helper->show_toolbar = false;
    $lang = new Language((int)Configuration::get('PS_LANG_DEFAULT'));
    $helper->module                   = $this;
    $helper->default_form_language    = $this->context->language->id;

    $helper->currentIndex  = $this->context->link->getAdminLink('AdminModules', false)
                             . '&configure=' . $this->name . '&tab_module=' . $this->tab . '&module_name=' . $this->name;
    $helper->token         = Tools::getAdminTokenLite('AdminModules');

    $helper->submit_action = 'submitform';
    return $helper->generateForm(array($fields_form));
}

第四步，在此目录下添加文件名form.tpl： icropper/views/templates/admin/_configure/helpers/form/form.tpl

内容如下：

{extends file="helpers/form/form.tpl"}
{block name="field"}
    {if $input.type == 'rangeslider'}
        <div class="col-lg-9">
            <div id="slider-range"></div>
            <p>
                <label for="amount">Price range:</label>
                <input type="text" id="amount" readonly style="border:0; color:#f6931f; font-weight:bold;">
            </p>
        </div>
        <script type="text/javascript">
        {literal}
            $( function() {
                $( "#slider-range" ).slider({
                     range: true,
                     min: {/literal}{$input.min|intval}{literal},
                     max: {/literal}{$input.max|intval}{literal},
                     step: {/literal}{$input.step|intval}{literal},
                     slide: function( event, ui ) {
                         $( "#amount" ).val( "$" + ui.values[ 0 ] + " - $" + ui.values[ 1 ] );
                     }
                });
                $( "#amount" ).val( "$" + $( "#slider-range" ).slider( "values", 0 ) +
                    " - $" + $( "#slider-range" ).slider( "values", 1 ) );
            });
        {/literal}
        </script>
    {else}
        {$smarty.block.parent}
    {/if}
{/block}

给你，这是将范围滑块添加到表单（或其他输入类型）的方法，顺便说一下，在这种情况下，我合并了 smarty 和 javascript q[= 的代码40=]ckness，但如果我们想要尊重 prestashop mvc，我们必须制作一个带有滑块初始化的不同 js 文件，太长无法解释 XD。干杯 ;).

如果我遗漏了什么请告诉我:)。
