I am getting a issue while fetching array data in Laravel 7 here is my code
https://i.stack.imgur.com/IZbg6.png
and the result is : https://i.stack.imgur.com/ByKaV.png
It is fetching only one array data. I don't know where i am missing.
If anybody know the error, please help me to solve this issue.
Below is my code ======================================
$cat_id = $category->id;
$location = null;
$sites = \DB::select( 'SELECT id FROM sites WHERE category_id = ?', [ $category->id ]);
$all = [ ];
foreach( $sites as $s ) {
$all[ ] = $s->id;
}
$sites = $all;
$all_cat_id = implode(',', array_map('intval', $sites));
// echo "<pre>";
// print($all_cat_id);
// die();
$sites = Sites::withCount('reviews')->orderBy('reviews_count', 'desc')->where('id', [$all_cat_id])->paginate(10);
return view('browse-category', [ 'activeNav' => 'home',
'reviews' => $reviews,
'sites' => $sites,
'category' => $category,
'all_categories' => $all_categories,
'location' => $location
]);
$sites = Sites::withCount('reviews')->orderBy('reviews_count', 'desc')->whereIn('id', [$all_cat_id])->paginate(10);
You need to use whereIn() instead of where()
whereIn() checks column against array.
I have created a dropdown which contains Job Positions. I want to disable the dropdown item which user has previously applied. Here to reduce my code i have created options_selected static to get selected job profile lists.
Here $job_positions contains all job profiles and $options_selected contains all the items which he previously selected from job_positions. Now he can't select these options again these should be disabled.
$job_positions =array('0' => 'Select', '1' => 'IT Staff', '2' => 'Customer Care', '3' => 'Sales', '4' => 'Doctor');
$options_selected =array('1' => 'IT Staff','2' => 'Doctor');
$opt_array=array();
// extract the job position
for ($i=0; $i < count($job_positions); $i++) {
$disabled = '';
// extract the options_selected and compare with the job position and if match overwrite the variable disabled
for ($x=1; $x <= count($options_selected); $x++) {
if ($options_selected[$x]==$job_positions[$i]) {
$disabled = 'disabled';
}
}
$opt_array[]= '<option '.$disabled.' value="'.$job_positions[$i].'">'.$job_positions[$i].'</option>';
}
echo form_dropdown('category', $opt_array);
You can use the array_diff() function which compare the values of two arrays and returns the differences.
$job_positions =array('0' => 'Select', '1' => 'IT Staff', '2' => 'Customer Care', '3' => 'Sales', '4' => 'Doctor');
$options_selected =array('1' => 'IT Staff','2' => 'Doctor');
$position = array_diff($job_positions,$options_selected);
echo form_dropdown('category', $position);
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 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;
