General error:1364 :Field 'dis' does not have a default value - php

Question

I am getting error 1364. Field 'dis' does not have a default value. I am going well with form and CRUD operation. In saving data in the database through form I got this error. Create form redirects to show view. I got this error when I click on the submit button of my form. I check my database data is not stored there.
Error:
Illuminate\Database\QueryException
SQLSTATE[HY000]: General error: 1364 Field 'dis' doesn't have a default value (SQL: insert into

Answer 1

You are not saving any data to dis field in your database, instead dis input field is saving data to gender field in your database. Do it like this
$student->dis=$request->dis;
or assign some default value to dis field in your database.

Answer 2

Here in your table dis column is not nullable. so when you save any row this column need to fill. To solve this problem you need to nullable this column or set a default value for this. add a new migration file & make this column nullable or set default value.
$table->text('dis')->nullable();
or
$table->text('dis')->default('your_disere_value');
Or save dis column value from blade to controller.
$student->dis=$request->dis;

Answer 3

You have to modify your primary key to NOT NULL like this:
ALTER TABLE employee_details MODIFY emp_id int NOT NULL AUTO_INCREMENT;
