In my controller, I am passing data to the model using the following code:
$data = array(
'gid' => $this->input->post('gid'),
'name' => $this->input->post('name'),
'pic' => $this->input->post('pic'),
'link' => $this->input->post('link')
);
var_dump($data);
$this->Login_model->insert_entry($data);
In my model, what I want to do is use the gid value as part of an SQL statement, like so:
$get_gid = $this->db->query('SELECT * FROM users WHERE gid = $gid');
Obviously this doesn't work, so I'm just wondering how I get the gid from $data and use it in my SQL statement?
Tested using
$get_gid = $this->db->where('gid', $data['gid'])->get('users');
print_r($get_gid);
However output is:
CI_DB_mysql_result Object ( [conn_id] => Resource id #30 [result_id]
=> Resource id #33 [result_array] => Array ( ) [result_object] => Array ( ) [custom_result_object] => Array ( ) [current_row] => 0
[num_rows] => 0 [row_data] => )
Did you try gid = $data['gid']
I assume that yours model method looks like this:
insert_entry($data)
{
here active record or query...
}
If yes try to display query to see if $data['gid'] is visible there
You can try it by
$this->db->get_compiled_select();
Or after query runs
$this->db->last_query();
Try this way:
$data = array(
'gid' => $this->input->post('gid'),
'name' => $this->input->post('name'),
'pic' => $this->input->post('pic'),
'link' => $this->input->post('link')
);
$gid = $data['gid'];
$this->db->where('gid',$gid);
$this->db->from('users');
$query = $this->db->get();
if($query)
{
//you can return query or you can do other operations here like insert the array data
//$this->db->insert('yourtable',$data);
return $query;
}
else
{
return FALSE;
}
You can try:
$get_gid = $this->db->query('SELECT * FROM users WHERE gid = '.$data['gid'].');
You just Forget after query $query->result().

This should be like this
ID|access1|access2|access3|
and values:
1|1|0|1
//myController
$basic_data = array();
$select_access1 = $_POST("select_access1");
$select_access2 = $_POST("select_access2");
$select_access3 = $_POST("select_access3");
$select_access4 = $_POST("select_access4");
$select_access5 = $_POST("select_access5");
$basic_data[] = array('accs_trans_sec'=>$select_access1,'accs_acctng_sec'=>$select_access2, 'accs_admin_sec'=>$select_access3,'accs_dashboard_sec'=> $select_access4, 'accs_reports_sec'=>$select_access5);
$this->RoleModel->saveRole($basic_data);
//myModel
public function saveRole($basic_data)
{
foreach($basic_data as $value) {
$this->db->insert('roles_global_access', $basic_data);
}}
You can set that data to array just like this:
$data = array(
'column1' => 'My Value 1',
'column2' => 'My Value 2',
'column3' => 'My Value 3'
);
$this->db->insert("table_name", $data);
Let's assume that you are getting the values of your checkbox based on your $_POST variables.
Since you've declared $basic_data as array() no need to cast it as $basic_data[].
So on your controller it should be like this:
$basic_data = array(
'accs_trans_sec'=>$select_access1,
'accs_acctng_sec'=>$select_access2,
'accs_admin_sec'=>$select_access3,
'accs_dashboard_sec'=> $select_access4,
'accs_reports_sec'=>$select_access5
);
And your model there's no need to use loop since you are inserting Object data it should look like this:
public function saveRole($basic_data)
{
$this->db->insert('roles_global_access', $basic_data);
return ($this->db->affected_rows() != 1) ? false : true;
}
so basically, if the model returns true then it successfully inserted the data.
To check if data is inserted successfully:
$result = $this->RoleModel->saveRole($basic_data);
if($result == true){
echo ("Successfully inserted!");
}else{
echo ("Problem!");
}
First, you are not getting post data in the correct way. With $_POST have to use square brackets [].
Second, Don't use foreach loop in the model
Get data in the controller like this
$basic_data = array(
'accs_trans_sec' => $_POST['select_access1'],
'accs_acctng_sec' => $_POST['select_access2'],
'accs_admin_sec' => $_POST['select_access3'],
'accs_dashboard_sec' => $_POST['select_access4'],
'accs_reports_sec' => $_POST['select_access5']
);
$this->RoleModel->saveRole($basic_data);
Model
public function saveRole($basic_data){
return $this->db->insert('roles_global_access', $basic_data);
}
You should try this.
Controller:
$this->RoleModel->saveRole($_POST);
Model:
public function saveRole($basic_data){
extract($basic_data);
$dataset = array(
'accs_trans_sec' => $basic_data['select_access1'],
'accs_acctng_sec' => $basic_data['select_access2'],
'accs_admin_sec' => $basic_data['select_access3'],
'accs_dashboard_sec' => $basic_data['select_access4'],
'accs_reports_sec' => $basic_data['select_access5']
);
$this->db->insert('roles_global_access', $dataset);
}
Im new in laravel, and im trying to update my navigation tree.
So i want to update my whole tree in one query without foreach.
array(
array('id'=>1, 'name'=>'some navigation point', 'parent'='0'),
array('id'=>2, 'name'=>'some navigation point', 'parent'='1'),
array('id'=>3, 'name'=>'some navigation point', 'parent'='1')
);
I just want to ask - is there posibility in laravel to insert(if new in array) or update my current rows in database?
I want to update all, because i have fields _lft, _right, parent_id in my tree and im using some dragable js plugin to set my navigation structure - and now i want to save it.
I tried to use
Navigation::updateOrCreate(array(array('id' => '3'), array('id'=>'4')), array(array('name' => 'test11'), array('name' => 'test22')));
But it works just for single row, not multiple like i tried to do.
Maybe there is another way to do it?
It's now available in Laravel >= 8.x
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 columns that should be updated if a matching record already exists in the database:
Flight::upsert([
['departure' => 'Oakland', 'destination' => 'San Diego', 'price' => 99],
['departure' => 'Chicago', 'destination' => 'New York', 'price' => 150]
], ['departure', 'destination'], ['price']);
I wonder why this kind of feature is not yet available in Laravel core (till today). Check out this gist The result of the query string would look like this: here
I am putting the code here just in case the link breaks in the future, I am not the author:
/**
* Mass (bulk) insert or update on duplicate for Laravel 4/5
*
* insertOrUpdate([
* ['id'=>1,'value'=>10],
* ['id'=>2,'value'=>60]
* ]);
*
*
* #param array $rows
*/
function insertOrUpdate(array $rows){
$table = \DB::getTablePrefix().with(new self)->getTable();
$first = reset($rows);
$columns = implode( ',',
array_map( function( $value ) { return "$value"; } , array_keys($first) )
);
$values = implode( ',', array_map( function( $row ) {
return '('.implode( ',',
array_map( function( $value ) { return '"'.str_replace('"', '""', $value).'"'; } , $row )
).')';
} , $rows )
);
$updates = implode( ',',
array_map( function( $value ) { return "$value = VALUES($value)"; } , array_keys($first) )
);
$sql = "INSERT INTO {$table}({$columns}) VALUES {$values} ON DUPLICATE KEY UPDATE {$updates}";
return \DB::statement( $sql );
}
So you can safely have your arrays inserted or updated as:
insertOrUpdate(
array(
array('id'=>1, 'name'=>'some navigation point', 'parent'='0'),
array('id'=>2, 'name'=>'some navigation point', 'parent'='1'),
array('id'=>3, 'name'=>'some navigation point', 'parent'='1')
)
);
Just in case any trouble with the first line in the function you can simply add a table name as a second argument, then comment out the line i.e:
function insertOrUpdate(array $rows, $table){
.....
}
insertOrUpdate(myarrays,'MyTableName');
NB: Be careful though to sanitise your input! and remember the timestamp fields are not touched. you can do that by adding manually to each arrays in the main array.
I've created an UPSERT package for all databases: https://github.com/staudenmeir/laravel-upsert
DB::table('navigation')->upsert(
[
['id' => 1, 'name' => 'some navigation point', 'parent' => '0'],
['id' => 2, 'name' => 'some navigation point', 'parent' => '1'],
['id' => 3, 'name' => 'some navigation point', 'parent' => '1'],
],
'id'
);
Eloquent Style
public function meta(){ // in parent models.
return $this->hasMany('App\Models\DB_CHILD', 'fk_id','local_fk_id');
}
.
.
.
$parent= PARENT_DB::findOrFail($id);
$metaData= [];
foreach ($meta['meta'] as $metaKey => $metaValue) {
if ($parent->meta()->where([['meta_key', '=',$metaKey]] )->exists()) {
$parent->meta()->where([['meta_key', '=',$metaKey]])->update(['meta_value' => $metaValue]);
}else{
$metaData[] = [
'FK_ID'=>$fkId,
'meta_key'=>$metaKey,
'meta_value'=> $metaValue
];
}
}
$Member->meta()->insert($metaData);
No, you can't do this. You can insert() multiple rows at once and you can update() multiple rows using same where() condition, but if you want to use updateOrCreate(), you'll need to use foreach() loop.
I didn't find a way to bulk insert or update in one query. But I have managed with only 3 queries. I have one table name shipping_costs. Here I want to update the shipping cost against the shipping area. I have only 5 columns in this table id, area_id, cost, created_at, updated_at.
// first get ids from table
$exist_ids = DB::table('shipping_costs')->pluck('area_id')->toArray();
// get requested ids
$requested_ids = $request->get('area_ids');
// get updatable ids
$updatable_ids = array_values(array_intersect($exist_ids, $requested_ids));
// get insertable ids
$insertable_ids = array_values(array_diff($requested_ids, $exist_ids));
// prepare data for insert
$data = collect();
foreach ($insertable_ids as $id) {
$data->push([
'area_id' => $id,
'cost' => $request->get('cost'),
'created_at' => now(),
'updated_at' => now()
]);
}
DB::table('shipping_costs')->insert($data->toArray());
// prepare for update
DB::table('shipping_costs')
->whereIn('area_id', $updatable_ids)
->update([
'cost' => $request->get('cost'),
'updated_at' => now()
]);
in your controller
use DB;
public function arrDta(){
$up_or_create_data=array(
array('id'=>2, 'name'=>'test11'),
array('id'=>4, 'name'=>'test22')
);
var_dump($up_or_create_data);
echo "fjsdhg";
foreach ($up_or_create_data as $key => $value) {
echo "key ".$key;
echo "<br>";
echo " id: ".$up_or_create_data[$key]["id"];
echo "<br>";
echo " Name: ".$up_or_create_data[$key]["name"];
if (Navigation::where('id', '=',$up_or_create_data[$key]["id"])->exists()) {
DB::table('your_table_ name')->where('id',$up_or_create_data[$key]["id"])->update(['name' => $up_or_create_data[$key]["name"]]);
}else{
DB::insert('insert into your_table_name (id, name) values (?, ?)', [$up_or_create_data[$key]["id"], $up_or_create_data[$key]["name"]]);
}
}
I am attempting to access the result set from a model query in the view. I have the following:
Controller:
$courseId = $this->session->userdata('courseId');
//echo "Course: ".$courseId;
if(isset($courseId) && $courseId != '')
{
$result = $this->Course_model->loadBasicDetailsEdit($courseId);
$data['basicCourseDetails'] = $result;
$this->load->view('course/basicDetails', $data);
}
Model:
function loadBasicDetailsEdit($courseId)
{
$this->db->select('*');
$this->db->where('course_id', $courseId);
$this->db->from('course');
$query = $this->db->get();
if ( $query->num_rows() > 0 )
{
return $query->result();
} else {
return FALSE;
}
}
and in the view I tried to print_r() and got this:
Array ( [0] => stdClass Object ( [course_id] => 8 [title] => Photography [summary] => [description] => [price] => [member_id] => 12 [category] => [audience] => [goals] => [date] => 2013-09-26 [production] => 0 ) )
I tried to access this using $basicCourseDetails->title or $basicCourseDetails['title']
but neither are working. Any hint as to why this is happening?
Regards,
try this:
foreach($basicCourseDetails as $basic){
echo($basic->title);
}
or something like this:
echo($basicCourseDetails[0]->title);
This is an array of objects
Array ( [0] => stdClass Object ( [course_id] => 8 [title] => Photography [summary] => [description] => [price] => [member_id] => 12 [category] => [audience] => [goals] => [date] => 2013-09-26 [production] => 0 ) )
Contains one stdObject in the array, so, first objects is 0, if there were more, then second item could have index 1 and so on. To retrieve data from the first (here is only one) stdobject you may use
echo $basicCourseDetails[0]->title; // title will be printed
You can send data to the view page by this line of code which is mentioned in above question.
$result = $this->Course_model->loadBasicDetailsEdit($courseId);
$data['basicCourseDetails'] = $result;
$this->load->view('course/basicDetails', $data);
But when you will access these data in view then you need to access all data one by one by using foreachloop in the view page.
For example if you have a view page like basic_details.php inside course folder then you need to write code like this to access these data.
foreach ($basicCourseDetails as $key => $value) {
$name = $value->name;
}
The above foreachloop can be written in view page where you want to access data.
I have the following query
public static function createConversation( $toUserId )
{
$now = date('Y-m-d H:i:s');
$currentId = Auth::user()->id;
$results = DB::table('pm_conversations')->insert(
array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now )
);
return $results;
}
How would i return the id of the row just inserted?
Cheers,
Instead of doing a raw query, why not create a model...
Call it Conversation, or whatever...
And then you can just do....
$result = Conversation::create(array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now ))->id;
Which will return an id...
Or if you're using Laravel 4, you can use the insertGetId method...In Laravel 3 its insert_get_id() I believe
$results = DB::table('pm_conversations')->insertGetId(
array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now )
);
This method requires that the id of the table be auto-incrementing, so watch out for that...
The last method, is that you can just return the last inserted mysql object....
Like so...
$result = DB::connection('mysql')->pdo->lastInsertId();
So if you choose that last road...
It'll go...
public static function createConversation( $toUserId )
{
$now = date('Y-m-d H:i:s');
$currentId = Auth::user()->id;
$results = DB::table('pm_conversations')->insert(
array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now )
);
$theid= DB::connection('mysql')->pdo->lastInsertId();
return $theid;
}
I would personally choose the first method of creating an actual model. That way you can actually have objects of the item in question.
Then instead of creating a model and just save()....you calll YourModel::create() and that will return the id of the latest model creation
You can use DB::getPdo()->lastInsertId().
Using Eloquent you can do:
$new = Conversation();
$new->currentId = $currentId;
$new->toUserId = $toUserId;
$new->ip = Request::getClientIp();
$new->time = $now;
$new->save();
$the_id = $new->id; //the id of created row
The way I made it work was I ran an insert statement, then I returned the inserted row ID (This is from a self-learning project to for invoicing):
WorkOrder::create(array(
'cust_id' => $c_id,
'date' => Input::get('date'),
'invoice' => Input::get('invoice'),
'qty' => Input::get('qty'),
'description' => Input::get('description'),
'unit_price' => Input::get('unit_price'),
'line_total' => Input::get('line_total'),
'notes' => Input::get('notes'),
'total' => Input::get('total')
));
$w_id = WorkOrder::where('cust_id', '=', $c_id)->pluck('w_order_id');
return $w_id;
I am using form_dropdown() and have a a problem below:
The form code is:
echo form_dropdown($level,$level_options,'1');
It works when I use
$level_options = array(
'1' => 'Grade 6',
'2' => 'Grade 7'
);
but not when I send a $data['levels'] from controller to view
For reference, the model database retrieve code is:
public function getAllLevelNames() {
$query = $this->db->query("SELECT level_description from levels ORDER BY level_description");
return $query->result_array();
}
The Problem
The problem is I get a dropdown pick list with:
0
Grade 6
1
Grade 7
The indexes are greyed out.
How do I get rid of the indexes?
Thanks in advance!
P.S.
I seem to have the form working now with a data['levels'] sent to the view. Now, the following code in my view seems to return "null" to my controller. Any ideas why please?
$level = array(
'name' => 'level',
'id' => 'level',
'value' => '1',
'maxlength' => '50',
'size' => '50',
'style' => 'width:50%',
);
$level_options = $levels;
echo "<p>Level: ";
echo form_dropdown($level,$level_options,'1');
Thanks!
You'll need to loop through your results_array and create a new array which is formatted correctly.
$query = $this->db->query("SELECT level_description from levels ORDER BY level_description");
$for_dropdown = array();
foreach ($query->result_array() as $row) {
$for_dropdown[$row->level_description] = $row->level_description;
}
return $for_dropdown;
Also I'm not sure how your levels table is structured, but usually you'll have an ID of some sort, which will be the primary key. If you do have that, you can include it in your query and have something like this instead:
$query = $this->db->query("SELECT id, level_description from levels ORDER BY level_description");
... // other code
$for_dropdown[$row->id] = $row->level_description;
