Question

我在wordpress网站上收到以下错误。知道我们做错了什么吗？这是在我们升级到WP 4.1.5

时开始的

注意：未定义的变量：第332行的/custom_helpers.php中的arr警告：第332行的/custom_helpers.php中为foreach（）提供的参数无效注意：未定义的变量：第332行的/custom_helpers.php中的arr警告：在第332行的/custom_helpers.php中为foreach（）提供的参数无效注意：在第339行的/custom_helpers.php中，类stdClass的对象无法转换为int注意：类stdClass的对象无法在/ custom_helpers中转换为int第345行的.php

这是第332行

function filter_pr_review( $field, $content ) {
if( empty($content) ) 
{
    if($field == 'lens_shift') return 'No';
    return false;
}

if( is_array( $content ) )
{
    return $content->name;
}
else
{

    foreach ($arr as $key => $value) {
        if( $key === $field )
        {
            return $content->name;
        }
    }

    if ($content == 0) 
    {
        return $content;
        //return $content->name;
        //return '0';
    }

   elseif($content == 1)
    {
        //return '1';
        //return $value;
        return $content->name;
        //return $content[1];
    }

这是生成表格的代码

未定义的变量：arr在/ ...第332行警告：为foreach（）提供的参数无效
