Issue is when you create table / schema, you didn't set your title column can be nullable,
问题是当您创建表/架构时，您没有设置标题列可以为空，
You can solve it with two ways. you can either change your table schema and set the title column nullable,
您可以通过两种方式解决它。您可以更改表架构并将标题列设置为可为空，
Schema::create("yourtablename" , function($table){
........
$table->string("title")->nullable();
........
});
or instead of Input::get("title") you can try with default value so even it is empty or null it will have a default value.
或者代替 Input::get("title") 你可以尝试使用默认值，这样即使它是空的或 null 它也会有一个默认值。
Input::get("title" , "No title");
