我在PHP中工作并从foreach{}
循环内部调用以下函数。此函数需要接受$subTheme
作为选项参数,因为目的是避免不必要的代码重复(DRY,对吧?)。
所以,首先 - 这里的功能是:
/*
* CSS needed to apply the selected styles to text elements.
*/
function this_site_text_css( $subTheme = '' ) {
$GLOBALS['this_theme_mod']; // this is in global scope already
$themeVarSuffix = $subTheme['var_suffix'];
$themeClassName = $subTheme['class_name'];
$content_bg_color = $this_theme_mod['content_bg_color' . $themeVarSuffix ];
$page_bg_color = $this_theme_mod['page_bg_color' . $themeVarSuffix ];
$primary_color = $this_theme_mod['primary_theme_color' . $themeVarSuffix ];
$css = 'body' . $themeClassName . '{ /* special classes */ };'
return $css
}
还有更多的事情发生,但它相当乏味,只是将CSS连接起来作为返回的字符串。
这样被称为
$data = '';
$data .= this_site_text_css();
$subThemeArray = array(
'theme_a' => array(
'var_suffix' => '_theme_a',
'class_name' => '.theme-a',
),
'theme_b' => array(
'var_suffix' => '_theme_b',
'class_name' => '.theme-b',
),
);
foreach( $subThemeArray as $key => $theme ) {
$data .= this_site_text_css( $theme );
}
我收到了PHP警告Illegal string offset 'class_name'
,我猜这是因为PHP在{{1}声明它时不希望我联接$themeVarSuffix
内联}}。我非常确定这是一种方法,而且我已经搜遍过,也许我还没有找到合适的关键字,但任何帮助都会受到赞赏。

非法字符串偏移'class_name'
...表示$subTheme
实际上是string
而不是array
。发生这种情况是因为您在函数声明$subTheme = ''
中有一个默认值,并且在调用它时错过了传递值,此处:
$data .= this_site_text_css();
所以$subTheme
是一个空字符串,当然没有索引'class_name'。

在$subThemeArray
数组中,应将theme_class
索引称为class_name
