通过编辑Avada子主题logo.php在WordPress网站上切换特定页面的logo

03-15 PHP 198

我正在尝试使特定页面在页眉中使用不同的徽标。我从Avada主题复制了logo.php文件到我的子主题文件夹(Avada-Child-Theme / templates / logo.php)。

我补充说：

    if (is_page(array (194, 248)))
{
  $standard_logo = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-binghamton-logo.png';
}

        if (is_page(array (194, 248)))
{
  $retina_logo = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-binghamton-logo.png';
}

这是完整的新logo.php文件：

我试过了：

$standard_logo[‘url’] = ‘/wp-content/uploads/2018/05/broadway-binghamton-logo.png’;

也一样当前文件仅适用于指定的页面, 但是我在这些页面的顶部看到此错误：

警告：第73行的/www/wp-content/themes/Avada-Child-Theme/templates/logo.php中的字符串偏移量’url’不合法

我不知道如何使它工作。网站是http://nac.flywheelsites.com/, 要查看, 联合国：flywheel PW：ideakraft

在主导航栏中的”城市”下, 我正在尝试更改宾厄姆顿的徽标。

图片网址正确。

我会将其放置在PHP文件中的错误位置吗？我尝试了几个不同的地方。请指教。非常感谢。

#1

不要将其设置为字符串-你在数组的正确位置上。

我认为你必须同时设置” url”和” srcset”：

// fetch logo normally
$standard_logo = Avada()->images->get_logo_image_srcset( 'logo', 'logo_retina' ); 

// see what that logo structure is like so you know what to override
// echo "<pre>"; print_r($standard_logo); echo "</pre>";


// if on these pages, override the srcset and url
        if (is_page(array (194, 248)))
        {
          $standard_logo['srcset'] = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-binghamton-logo.png';
          $standard_logo['url'] = $standard_logo['srcset'];
          $retina_logo['srcset'] = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-binghamton-logo.png';
          $retina_logo['url'] = $retinal_logo['srcset'];
        }

否则, 我不会立即看到任何问题。 。 。确保阵列中的ID是正确的。并确保在使用Avada函数正常提取徽标后放置IF条件, 否则Avada函数将覆盖新变量。

#2

答案是将每种徽标类型(标准, 移动等)的自定义徽标放置在图像源esc_url_raw()函数上方。

<?php $standard_logo = Avada()->images->get_logo_image_srcset( 'logo', 'logo_retina' ); ?>
        <!-- custom standard logos -->
        <?php
        //Binghamton
        if (is_page( 194 ))
        {
          $standard_logo['srcset'] = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-binghamton-logo.png';
          $standard_logo['url'] = $standard_logo['srcset'];
          $retina_logo['srcset'] = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-binghamton-logo-retina.png';
          $retina_logo['url'] = $standard_logo['srcset']; 
        } 
        //Erie
        if (is_page( 248 ))
        {
          $standard_logo['srcset'] = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-erie-logo.png';
          $standard_logo['url'] = $standard_logo['srcset'];
          $retina_logo['srcset'] = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-erie-logo.png';
          $retina_logo['url'] = $standard_logo['srcset']; 
        } 
        //Scranton
        if (is_page( 250 ))
        {
          $standard_logo['srcset'] = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-scranton-logo.png';
          $standard_logo['url'] = $standard_logo['srcset'];
          $retina_logo['srcset'] = 'http://nac.flywheelsites.com/wp-content/uploads/2018/05/broadway-scranton-logo.png';
          $retina_logo['url'] = $standard_logo['srcset']; 
        } 
        ?>
        <!-- standard logo -->
        <img src="<?php echo esc_url_raw( $standard_logo['url'] ); ?>" srcset="<?php echo esc_attr( $standard_logo['srcset'] ); ?>" width="<?php echo esc_attr( $standard_logo['width'] ); ?>" height="<?php echo esc_attr( $standard_logo['height'] ); ?>"<?php echo $standard_logo['style']; // WPCS: XSS ok. ?> alt="<?php echo esc_attr( $logo_alt_attribute ); ?>" retina_logo_url="<?php echo esc_url_raw( $standard_logo['is_retina'] ); ?>" class="fusion-standard-logo" />

页面条件运行良好, 通过回显进行了测试。刚需要在打印徽标图像之前执行自定义代码。
