我已经把范围缩小到了额外的数组代码,它似乎没有被读取(也许?)。以下是我的创建函数:
public function create()
{
// They are trying to put this live
if ($this->input->post('status') == 'live')

$extra
数组似乎未被读取。这些错误与数组到字符串错误同时发生。我本来希望这两个问题都能解决,但到目前为止还没有好结果。错误也来自两个方面。我在想,可能是因为没有人读那句话?或者它可能与文件开头的$validation\u规则有关
这一位代码是第一个失败的代码(对于$type
),也是唯一一个通过实际controller.php文件失败的代码,其余代码(关键字、标题、slug等)在form.php文件下失败
$post->type或$post->type='wysiwyg advanced'代码>
任何建议或帮助都将不胜感激。我对PHP和CodeIgniter还是相当陌生的,但是看起来要彻底检查这个网站需要做很多工作
多谢各位

替换
$post->type或$post->type='wysiwyg advanced'代码>
与
希望它能在您的代码中工作。:
$post->type or $post->type = 'wysiwyg-advanced';
PHP将首先计算$post->type
,如果返回false,将运行或
语句的第二部分。由于PHP必须对其求值,它将尝试访问该属性,并且由于未设置该属性,解释器将抛出一个通知并假定它为false
正确的方法是:
if (!isset($post->type)) {
$post->type = 'wysiwyg-advanced';
}
// Or in PHP 7:
$post->type = $post->type ?? 'nobody';
问题具体在哪一行?在这段代码中,有一个错误指向“$post->type或$post->type=”wysiwyg advanced“;”行,特别是:'遇到PHP错误严重性:注意消息:未定义属性:stdClass::$type'编码器试图聪明,但代码不正确。请看下面我的答案。这修复了一个错误,但没有修复其余的错误。其他错误指向form.php。每一行都类似于将其放在主帖子的编辑中。感谢您为消除这个特定错误所做的努力,但我并不完全确定这是解决这个问题的最佳方式。但它肯定没有修复任何其他错误。
if (!isset($post->type)) {
$post->type = 'wysiwyg-advanced';
}
// Or in PHP 7:
$post->type = $post->type ?? 'nobody';
