從Php函數檢索數據

Question

如何從PHP函數獲取數據？ 我想通過以下方式調用圖標：

<i class="<?php $this->Html->_($value['icon']);?>"></i>

不行。

如果有效的話就是這樣

<i class="fa fa-cloud"></i>

但是，如果調用另一個函數，例如：

<a href="#"><?php $this->Html->_($value['name']); ?></a>

做得好

主要的PHP功能：

/**
 * Retrieves the primary navigation for the client interface
 *
 * @param string $base_uri The base_uri for the currently logged in user
 * @return array An array of main navigation elements in key/value pairs
 *  where each key is the URI and each value is an array representing that element including:
 *     - name The name of the link
 *     - active True if the element is active
 *     - sub An array of subnav elements (optional) following the same indexes as above

public function getPrimaryClient($base_uri)
{
    $nav = [
        $base_uri => [
            'name' => $this->_('Navigation.getprimaryclient.nav_dashboard'),
            'active' => false
        ],
        $base_uri . 'accounts/' => [
            'name' => $this->_('Navigation.getprimaryclient.nav_paymentaccounts'),
            'active' => false,
            'secondary' => [
                $base_uri . 'accounts/' => [
                    'name' => $this->_('Navigation.getprimaryclient.nav_paymentaccounts'),
                    'active' => false,
                    'icon' => 'fa fa-list'
                ],
                $base_uri . 'accounts/add/' => [
                    'name' => $this->_('Navigation.getprimaryclient.nav_paymentaccounts_add'),
                    'active' => false,
                    'icon' => 'fa fa-plus-square'
                ],
                $base_uri => [

            ]
        ]
    ];

    // Include the primary client's plugin navigation
    return $this->getPluginNavPrimaryClient($nav, $base_uri);

我想在這里調用圖標，因為我標記為//獲取圖標

                        <?php
                        $active_nav = null;
                        ?>
                        <ul class="nav navbar-nav">
                            <?php
                            foreach ($this->Html->ifSet($nav, array()) as $link => $value) {
                                $attributes = array();
                                $link_attributes = array();
                                $dropdown = !empty($value['sub']);
                                $active = false;

                                if ($value['active']) {
                                    $active = true;
                                    $attributes['class'][] = "active";
                                    $active_nav = $value;
                                }
                                if ($dropdown) {
                                    $attributes['class'][] = "dropdown";

                                    // Set parent to active if child is

                                            if ($sub_value['active']) {

                            ?>

                                <a href="<?php $this->Html->_($link);?>"<?php echo $this->Html->buildAttributes($link_attributes);?>>

            // Get Icon

                            ?>
                        </ul>

有人對此有任何想法嗎？

我真的很感謝所有幫助。

Answer 1

好吧，這是可行的b

<i class="<?php $this->Html->_($value['name']);?>"></i>

因為有name屬性是第一個基本URI

$base_uri => [
        'name' => $this->_('Navigation.getprimaryclient.nav_dashboard'),
        'active' => false
    ],

如果您還添加圖標，它將起作用

$base_uri => [
        'name' => $this->_('Navigation.getprimaryclient.nav_dashboard'),
        'active' => false,
        'icon' => 'fa fa-cloud' 
    ],

希望這可以幫助。
