来自深字符串的奇怪的未定义索引错误

Question

我知道还有一个类似的问题，但我的问题看起来很奇怪。深层位置的字符串（如果我错了，我很抱歉，我是新手。）。我是运行一个 PHP 脚本，并且不断收到如下错误：

Notice: Undefined index: default in D:\SERVER-MYWEB\InstantWP_4.3.1\iwpserver\htdocs\wordpress\wp-content\themes\MYTHEME\admin\library\options\options.php on line 843

第 843 行如下所示：

$value['default']['font-family']);

这里是代码：

$family = isset($option['font']) && $option['font'] ? $option['font'] :
(isset($value['default']['font-family'])?$value['default']['font-family']:
$value['default']['font-family']);

编辑完整代码：

  <?php
 }

 function upfw_typography($value,$attr){
global $up_options,$up_fonts,$wpdb;

  $option = (isset($up_options->$value['id'])?$up_options->$value['id']:'');
if(!$option):
    global $default_options;
    $option = isset($value['value'])?$value['value']:array();
endif;

 $family = isset($option['font']) && $option['font'] ? $option['font'] : (isset($value['default']['font-family'])?$value['default']['font-family']:$value['default']['font-family']);
$fontsize = isset($option['fontsize']) && $option['fontsize'] ? $option['fontsize']: (isset($value['default']['font-size']) ? $value['default']['font-size'] : '');
$fontstyle = isset($option['fontstyle']) && $option['fontstyle'] ? $option['fontstyle']: (isset($value['default']['font-style']) ? $value['default']['font-style'] : '');   

    $lineheight = isset($option['lineheight']) && $option['lineheight'] ? $option['lineheight'] : (isset($value['default']['line-height']) ? $value['default']['line-height'] : '');
    $texttransform = isset($option['texttransform']) && $option['texttransform'] ? $option['texttransform'] : (isset($value['default']['text-transform']) ? $value['default']['text-transform'] : '');
    $fontweight = isset($option['fontweight']) && $option['fontweight'] ? $option['fontweight'] : (isset($value['default']['font-weight']) ? $value['default']['font-weight'] : '');
   $textdecoration = isset($option['textdecoration']) && $option['textdecoration'] ? $option['textdecoration'] : (isset($value['default']['text-decoration']) ? $value['default']['text-decoration'] : '');
    $textshadow = isset($option['textshadow']) && $option['textshadow'] ? $option['textshadow'] : (isset($value['default']['text-shadow']) ? $value['default']['text-shadow'] : '');
    $letterspacing = isset($option['letterspacing']) && $option['letterspacing'] ? $option['letterspacing'] : (isset($value['default']['letter-spacing']) ? $value['default']['letter-spacing'] : '');   
    $show_selector = (isset($value['show_selector']) ? $value['show_selector'] : '');
    $selector = isset($option['selector']) && $option['selector'] ? $option['selector'] : (isset($value['selector']) ? $value['selector'] : '');
    $fonts = $up_fonts; ?>

是否有解决这些错误的快速修复方法？非常感谢您的帮助

谢谢

Answer 1

您应该在使用前检查 default 索引：

if(isset($value['default'])) { 
//your code here
$family = isset($option['font']) && $option['font'] ? $option['font'] :
(isset($value['default']['font-family'])?$value['default']['font-family']:
$value['default']['font-family']);
}

Answer 2

那

呢

$family = (isset($option['font']) && $option['font'])? $option['font'] :((isset($value['default']))?((isset($value['default']['font-family']))?$value['default']['font-family']:"Arial"):"Arial");
