i want to update a single column (tuple) within attribute in table. i have the array shown below in controller.
$promotion_info = array(
'category' => $this->input->post('category'),
'rank' => $this->input->post('rank'),
'date_of_start' => $date_of_promotion
);
i passed it to model as shown below:-
$this->insert_model->form_promotion($fno, $promotion_info);
on model i want to update column with date_of_promotion. Then inserting a new row (attribute) with the value contained in array.
how can i update that column with the single value in array
Following docs:
$this->db->set('field', 'field+1', FALSE);
$this->db->where('id', 2);
$this->db->update('mytable'); // gives UPDATE mytable SET field = field+1 WHERE id = 2
$this->db->set('field', 'field+1');
$this->db->where('id', 2);
$this->db->update('mytable'); // gives UPDATE `mytable` SET `field` = 'field+1' WHERE `id` = 2
In your case it could be something like:
$array = array(
'category' => $name,
'rank' => $title,
'date_of_start' => $status
);
$this->insert_model->form_promotion($fno, $data);
In model:
$this->db->set($data);// this is case if you need to update all 3 values
//if you need to update only one value from the array than
//$this->db->set('date_of_start', $data['date_of_start']);
$this->db->where('date_of_start', "SOME_EXISTING_DATE_FROM_TABLE");
$this->db->insert('mytable');//

I want to retrieve the row data from table course where program_vss has null and 2 value.
return $this->db->get_where('course', array('is_top_course' => 1, 'status' => 'active', 'program_vss'=> null , ));
any suggestions on how to retrieve data with two conditions
you can use an array and pass the array:-
Associative array method:-
$array = array('name' => $name, 'title' => $title, 'status' => $status);
$this->db->where($array);
// Produces: WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
When I insert a new record into a database table, I need to take an existing previous value of a column called el_order, add +1, and use that new el_order+1 to insert the new record with that value in the column.
I can't use autoincrement because I need to do some things with that column (reorder, move, etc) and have to use it as an integer.
Table
ID name el_order
1 1 1
21 bla 2
2 2 3
--NEW-- --NEW-- 3+1 (NEW)
I add a new record, and need to insert it with 3+1 in it's el_order column...
I have tried this, but no luck:
$this->db->select_max('el_order');
$res = $this->db->get('elem_diccio');
$eldi_key = url_title($this->input->post('id'), 'underscore', TRUE);
$el_order = $res+1;
$datos = array(
'ID' => $id,
'el_order' => $el_order,
'name' => $this->input->post('name'),
);
$this->db->insert('elem_diccio', $datos);
Just like this
$this->db->select_max('el_order');
$res = $this->db->get('elem_diccio')->row()->el_order;
$eldi_key = url_title($this->input->post('id'), 'underscore', TRUE);
$el_order = $res+1;
$datos = array(
'ID' => $id,
'el_order' => $el_order,
'name' => $this->input->post('name'),
);
$this->db->insert('elem_diccio', $datos);
$res is a CI_DB_mysqli_result Object. To get the column, you need
$this->db->select_max('el_order');
$res = $this->db->get('elem_diccio')->row();
$el_order = $res->el_order+1;
$datos = array(
'ID' => $id,
'el_order' => $el_order,
'name' => $this->input->post('name'),
);
Laravel provides a great help for developers to save all input fields of a form which is one record with one line of code.
like if I want to save a form which has multiple input fields and one record to database like:
then I can save it with below code and it works great:
SaveOrder:: create($request->all());
Now I have a question. If I have multiple records (multiple rows) in a form and I can add new rows with a button pressed. Then how can I save all records with above code?
Like:
It's easy to do that using Eloquent :
$data = array(
array('field1'=>'value1', 'field2'=> value2),
array('field1'=>'value1', 'field2'=> value1),
//...
);
Model::insert($data);
Assuming your input names look something like name[], since you can add rows on the fly, you can retrieve the input as an array, and insert them using something like this:
$data = [];
$names = request('name');
$product_names = request('product_name');
$product_colour = request('product_colour');
$product_size = request('product_size');
for ($i = 0; $i < count($names); $i++) {
// Add checks to make sure indices actually exist, probably using preprocessing in JS
$data[] = [
'name' => $names[$i],
'product_name' => $product_names[$i],
'product_colour' => $product_colour[$i],
'product_size' => $product_size[$i],
];
}
Model::insert($data);
The best answer for this question is using foreach statement. Like:
$CustomerName= $request -> input('CustomerName');
$ProductId= $request -> input('ProductId');
$ProductName= $request -> input('ProductName');
$ProductColor= $request -> input('ProductColor');
foreach( $ProductId as $key => $n ) {
SaveOrder::insert(
array(
'CustomerName' => $CustomerName[$key],
'ProductId' => $ProductId[$key],
'ProductName' => $ProductPrice[$key],
'ProductColor' => $ProductQuantity[$key],
)
);}
Use upsert
If you use Laravel 8 or above, you can make use of upsert. Such an useful function to insert or update matching records at the same time.
SaveOrder::upsert($request->all(), ['id'], ['CustomerName', 'ProductName', 'ProductColor', 'ProductID']);
The method's first argument consists of the values to insert or update, while the second argument lists the column(s) that uniquely identify records within the associated table. The method's third and final argument is an array of the columns that should be updated if a matching record already exists in the database. The upsert method will automatically set the created_at and updated_at timestamps if timestamps are enabled on the model:
Flight::upsert([
['departure' => 'Oakland', 'destination' => 'San Diego', 'price' => 99],
['departure' => 'Chicago', 'destination' => 'New York', 'price' => 150]
], ['departure', 'destination'], ['price']);
Read the documentation on Laravel Upsert
Is it possible to update a timestamp (besides updated_at) and increment a column in one query? I obviously can
->increment('count')
and separately
->update(['last_count_increased_at' => Carbon::now()])
but is there an easy way to do both together.
Product::where('product_id', $product->id)
->update(['count'=> $count + 1, 'last_count_increased_at' => Carbon::now()];
Without having to query and get the count first?
You can specify additional columns to update during the increment or decrement operation:
Product::where('id',$id)
->increment('count', 1, ['increased_at' => Carbon::now()]);
It is more eloquent solution.
You can use the DB::raw method:
Product::where('product_id', $product->id)
->update([
'count'=> DB::raw('count+1'),
'last_count_increased_at' => Carbon::now()
]);
With Laravel 8 you can now achieve this in a single query to create or update on duplicate key.
$values = [
'name' => 'Something',
'count' => 1,
];
$uniqueBy = ['name'];
$update = ['count' => DB::raw('count+1')];
Model::upsert($values, $uniqueBy, $update);
If the model exists count will be incremented, if it is inserted count will equal 1. This is done on the DB level, so only one query involved.

Im trying to insert the following array into my table to no avail. I tried several examples but none worked.
Each POST array contains two strings from an input form (each string from an input row) and the $data keys are of the same name of the columns in the table.
How do I insert this data into two rows with a single query?
$data = array(
'user_id' => $_POST['user_id'],
'order' => $_POST['order'],
'type' => $_POST['type'],
'series' => $_POST['series'],
'repetition' => $_POST['repetition'],
'load' => $_POST['load'],
'pause' => $_POST['pause']
);
EDIT.: Could swear I had copied the query.
$columns = implode(',',array_keys($data));
$values = implode(',',array_values($data));
$query = " INSERT INTO userdata ($columns) VALUES ($values)";
You can insert this type of array like this
$fields=" ".implode(",",array_keys($data))." ";
$data="'".implode ("','",$data)."'";
$query ="INSERT INTO table_name ($fields) VALUES ($data)";
if($query){
mysql_query($query);
}
