我们可以使用类似于注册默认标题的过程向WordPress中的主题添加自定义背景图像支持。这是你的捷径!
$defaults = array(
\'default-color\' => \'\',
\'default-image\' => \'%1$s/images/background.jpg\',
\'default-repeat\' => \'repeat\',
\'default-position-x\' => \'left\',
\'default-position-y\' => \'top\',
\'default-size\' => \'auto\',
\'default-attachment\' => \'scroll\',
\'wp-head-callback\' => \'_custom_background_cb\',
\'admin-head-callback\' => \'\',
\'admin-preview-callback\' => \'\'
);
add_theme_support( \'custom-background\', $defaults );
还有两种方法可以实现它:
1-我们可以通过玩一些把戏和加载预设图像来实现这一点。
添加过滤器(\'body\\u class\',\'random\\u background\\u images\');函数random\\u background\\u image($类){
// Generate Random number from 1 to 10.
$background_class = \'background_\' . rand(1,10);
$classes[] = $background_class;
return $classes;
}
将上述代码添加到wordpress主题函数中。php文件。它将从background\\u 1到background\\u 10添加一个随机的body类
现在,您可以根据需要为它们添加css。
身体background\\u 1{背景图片:url(“images/home-bg/website-background1.jpg”);}身体background\\u 2{背景图片:url(“images/home-bg/website-background2.jpg”);}身体background\\u 3{背景图片:url(“images/home-bg/website-background3.jpg”);}

var imgCount = images.length;
var randNumber=Math.floor((Math.random() * imgCount) + 1);
imgURL = "url(\'" + images[randNumber-1] + "\')";
var body=document.getElementById(\'collection-542ba4a1e4b032a0dde82b31\');
body.style.backgroundImage=imgURL;
body.style.backgroundSize="100% auto";
body.style.backgroundRepeat="no-repeat";
}());
