You shouldn't put more than two lines in URL address. Check you URL.
您不应该在 URL 地址中放置超过两行。检查你的网址。
Good URL - "http://mail.google.com" - 1 line
Bad URL - "http://mail. - 2 lines
google.com/"

Trouble could be in your phpMyAdmin, table wp_options, option_value.
问题可能出在您的 phpMyAdmin、表 wp_options、option_value 中。
If there is a spacebefore the URL it will generate the ERROR: warning: header may not contain more than a single header, new line detected in...
如果URL 前有空格，它将生成错误：警告：标头可能不包含多个标头，在...中检测到新行

This warning occurs to indicate that you might have a new line [/n] in the string content of your variables. Example
出现此警告表明您的变量的字符串内容中可能有一个新行 [/n]。例子
header("Location: ../control.php?post='$title1'&sample='$val'");
here there are 2 variables
这里有2个变量
$title1 and & $val
$title1 和 & $val
so while running if This warning occurs warning
所以在运行时如果出现此警告警告
“Header may not contain more than a single header, new line detected”
“标题不能包含多个标题，检测到新行”
The solution isTo strip out the passable new line contents of the variable Like this
解决办法是去掉变量的可通过的新行内容像这样
$val=str_replace(PHP_EOL, '', $val);
$title1=str_replace(PHP_EOL, '', $title1);
Then you can include the variables in the header
然后你可以在标题中包含变量
The ideal way of solving it is like this
理想的解决方法是这样的
$url="../control.php?post='$title1'&sample='$val'";
$url=str_replace(PHP_EOL, '', $url);
header("Location: $url");
** This will work 100%;**
** 这将 100% 有效；**

Seems like the variables you are using to create the Location attribute has a new line character in them. Pass them through urlencode()
似乎您用来创建 Location 属性的变量中有一个换行符。通过urlencode()传递它们

Try encoding your URL and it should work : http://php.net/manual/en/function.urlencode.php
尝试对您的 URL 进行编码，它应该可以工作：http: //php.net/manual/en/function.urlencode.php

You should put the URL "http://example.comlike this , please avoid "http://example.com/" "/" does give URL Mismatch , so avoid , Same problem will comes wordpress also. So try to use like this.
您应该像这样输入“ http://example.com” ，请避免“ http://example.com/”“/”确实会导致 URL 不匹配，因此请避免，wordpress 也会出现同样的问题。所以尝试使用像这样。
