警告：SQLite3 :: query（）[sqlite3.query]：2列的1个值

Question

I am using an sqlite3 db in php wich i want to fill, i need to fill in a foreign key and the name of the subcategory, here's the code that i use.

var_dump('"'.$categoryRow.','.$subcategory.'"');
            $db->query('INSERT INTO Subcategories (fk_cat, subcat) VALUES ("'.$categoryRow.','.$subcategory.'")');
            $subCategoryRow = $db->lastInsertRowID();
            die();

But when i run this code, it returns:

string(11) ""1,subcategory"" 
Warning: SQLite3::query() [sqlite3.query]: 1 values for 2 columns in /mysite/product.php on line 94

but when i log them i get 1 and ''subcategory' back.

Does anyone know what i am doing wrong?

Answer 1

your variables should be both surrounded by double quotes sql should be insert into (field1, field2) values ("value1","value2")

var_dump('"'.$categoryRow.','.$subcategory.'"');
            $db->query('INSERT INTO Subcategories (fk_cat, subcat) VALUES ("'.$categoryRow.'","'.$subcategory.'")');
            $subCategoryRow = $db->lastInsertRowID();
            die();
