Url 参数值不能是数组
Url parameters values can not be arrays
我正在使用 Moodle 版本 3.8.4+ 和 PHP 版本 7.2.33。今天我在尝试给学生发消息时发现一个奇怪的问题,消息是:
Coding error detected, it must be fixed by a programmer: Url parameters values can not be arrays! More information about this error
我清除了所有缓存,因为建议是在“更多信息”部分,但它没有用。
我在调试模式下 运行 相同的 Moodle 版本和 PHP 版本在非生产环境中,然后我收到此错误消息:
Coding error detected, it must be fixed by a programmer: Url parameters values can not be arrays!

```php
看起来启动此过程的请求中的 massagebody
参数使用的是数组语法,例如 ?messagebody[]=foo
而不是 ?messagebody=foo
,因此错误出现在请求的任何页面中来源于。您可以尝试找出原因并进行更改,或者更改此 messageselect.php 文件以展平参数。为此,您需要更改此设置:
<?php
if ($messagebody !== '') {
$url->param('messagebody', $messagebody);
}
对此:
<?php
if ($messagebody !== '') {
if(is_array($messagebody))
{
$messagebody = array_shift($messagebody);
}
$url->param('messagebody', $messagebody);
}
但是请注意,如果页面将此参数作为数组发送,则很可能其他页面也会以这种方式发送。通常您会使用数组语法发送参数,以便可以在一个请求中处理多个记录,这样 messagebody[1] 就会关联到 format[1],messagebody[2] 就会关联到 format[2],等等。 messageselect.php 中的代码显然没有预料到这一点。我很想知道发送请求的页面的故事是什么。
