Most times when working with MySQL, it is possible that a blank row is Inserted before new data row in MySQL database, as seen in the image below.
If you receive an error message while trying to insert a blank row into a MySQL table, it may be because the table has one or more columns that do not allow null values. In this case, you’ll need to specify a valid default value for each column in the table, or update the table’s schema to allow null values.
Learning software development is a very interesting process as you can experience errors like this often
First, you need to verify that you are in fact not calling mysql_query() twice!
If you’re now certain that you are indeed not actually inserting twice into the MySQL table, then you need to stop the code from executing twice by specifying the REQUEST METHOD.
You specify that by adding the following code:
if($_SERVER['REQUEST_METHOD'] == 'POST'){
// your code here ...
}
This should solve the blank row insertion problem.
Also, you need to be sure you correctly inserting the right values into the right column.
To insert a row with default values, you can use the following syntax:
INSERT INTO your_table_name (column1, column2, column3) VALUES ('default_value1', 'default_value2', 'default_value3');
Replace your_table_name
, column1
, column2
, and column3
with the actual table and column names you’re working with, and default_value1
, default_value2
, and default_value3
with the default values you want to use for each column.
