I'm trying to add a new column to the database with dbforge of Codeigniter but it returns only error messages doesn't get into else column
My Error :
Duplicate column name 'github'
ALTER TABLE social-settings ADD github VARCHAR(255)
I know there is a column name github but it doesn't get into else column, it inserts two tables in database if column adding fails, I need to delete from other tables
$last_id=$this->Forms_model->newArea($this->input->post());
if ($last_id!=false) {
$this->load->dbforge();
$fields = array(
$this->input->post("element_name") => array(
'type' => 'VARCHAR',
'constraint' => '255',
),
);
$table = $this->input->post("element_form_id") == 2 ? "contact-settings" : "social-settings";
if ($this->dbforge->add_column($table, $fields)) {
echo json_encode(returnJson(1, "Yeni form alanı ekleme işlemi başarılı."));
} else {
echo $this->Forms_model->turnToOld($last_id) == true ? json_encode(returnJson(0, "Yeni form alanı ekleme işlemi bir sebepten dolayı başarısız oldu.")) : json_encode(returnJson(0, "İşlemler yapılırken bazı hatalar oluştu, lütfen geliştiricinizle iletişime geçin."));
}
}
There must be a column with that name that already exists in the table.
You should use $this->db->field_exists() to check if the column exists before issuing the add_column statement.
$el = $this->input->post("element_name");
if (is_null($el)) {
show_error('element is null');
}
if (!$this->db->field_exists($el, 'table_name')) {
// dbforge
}
