新！

好吧我删除了bg选项，但现在我从font-family中得到错误..

Warning: Illegal string offset 'font-family' in .../wp-content/themes/curves/includes/custom-css.php on line 20

Warning: Illegal string offset 'font-family' in ..../wp-content/themes/curves/includes/custom-css.php on line 56

我认为这不好写

$h1_font = ot_get_option( 'h1_font', 'lato' );

$custom_css = "
h1 { 
    font-family: ". $h1_font['font-family'] .";
    font-size: ". ot_get_option( 'h1_size', '24' ). "px;
    font-weight: 300;
}

任何帮助？ THX

PHP 5.4有一些问题..我有一个为我编写代码的朋友，因为我只是设计，现在这个人无法访问...我在这里：）

所以我有customcss.php为Wordpress主题创建dynamic.css。我已经在主机gator上安装了主题为PHP 5.4并且我得到了这个警告：

等。

if($body_bg['background-image'] != ""){

$custom_css .= "}";

此代码将在admin（选项树）中选择的选项应用于内联css。

在PHP 5.3中它可以工作，但在PHP 5.4中它会显示警告。

此外，我发现发生这种情况是因为，当我第一次安装主题时，在选项树中没有选择font-family这样的选项，尽管您可以看到我设置了默认值。

Answer 1

在使用数组成员之前，首先应检查是否通过例如：

进行设置

if(isset($body_bg['background-image'])) {
    // do something with it
}

中的答案

例如，您可以执行以下操作：

$h1_font = ot_get_option( 'h1_font', 'lato' );

$h1_font_family = "sans-serif";
if(isset($h1_font['font-family']))
    $h1_font_family = $h1_font['font-family'];

$custom_css = "
h1 { 
    font-family: ". $h1_font_family .";
    font-size: ". ot_get_option( 'h1_size', '24' ). "px;
    font-weight: 300;
}

等等，您想要定义的所有样式。您提供的是默认值（"sans-serif"），如果您的选项中的设置'font-family'可用，则会替换默认值。
