Searching multiple columns through traits in Laravel - php

Question

By checking out this tutorial I'm implementing a search url in my Laravel 5.4 application. I've implemented a trait in my model for example if I'm having Company model so in model I'm including my trait something like this:
class Company extends Model
{
use SoftDeletes, DataViewer;
protected $fillable = [
'name', 'address', 'city', 'state', 'country', 'type', 'sub_type',
];
public static $columns = [
'name', 'address', 'city', 'type', 'sub_type'
];
}
Now I'm having this DataViewer trait something like this:
trait DataViewer {
protected $operators = [
'equal' => '=',
'not_equal' => '<>',
'less_than' => '<',
'greater_than' => '>',
'less_than_or_equal_to' => '<=',
'greater_than_or_equal_to' => '>=',
'in' => 'IN',
'like' => 'LIKE'
];
public function scopeSearchPaginateAndOrder($query)
{
$request = app()->make('request');
return $query
->orderBy($request->column, $request->direction)
->where(function($query) use ($request) {
if($request->has('search_input')) {
if($request->search_operator == 'in') {
$query->whereIn($request->search_column, explode(',', $request->search_input));
} else if($request->search_operator == 'like') {
$query->where($request->search_column, 'LIKE', '%'.$request->search_input.'%');
}
else {
$query->where($request->search_column, $this->operators[$request->search_operator], $request->search_input);
}
}
})
->paginate($request->per_page);
}
}
And I'm calling this in controller something like this:
public function getData()
{
$models = Company::searchPaginateAndOrder();
return response()->json([
'model' => $models
]);
}
And to achieve this I'm calling url something like this:
http://stellar.dev/api/companies?column=name&direction=asc&page=1&per_page=50&search_column=name&search_operator=like&search_input=icici
The problem which I'm facing here is that it can search can only through one column, I want to have search with multiple columns in one query. Suggest me what can be done.
Thanks.

Answer 1

You should make your query string as an array for multiple columns like this.
http://stellar.dev/api/companies?column=name&direction=asc&page=1&per_page=50&search_column[]=name&search_operator[]=like&search_input[]=icici&search_column[]=lastname&search_operator[]=like&search_input[]=asd
Then read and use them as an array. Also you need to check their length to prevent unexpected errors. Then you can simple use a simple loop to concatenate your conditions like the following code block.
trait DataViewer {
protected $operators = [
'equal' => '=',
'not_equal' => '<>',
'less_than' => '<',
'greater_than' => '>',
'less_than_or_equal_to' => '<=',
'greater_than_or_equal_to' => '>=',
'in' => 'IN',
'like' => 'LIKE'
];
public function scopeSearchPaginateAndOrder($query)
{
$request = app()->make('request');
$searchInputs = $request->get('search_input', []);
$searchOperators = $request->get('search_operator', []);
$searchColumns = $request->get('search_column', []);
$query->orderBy($request->column, $request->direction);
if(count($searchInputs) == count($searchOperators) && count($searchOperators) == count($searchColumns)) {
$query->where(function($query) use ($searchInputs, $searchOperators, $searchColumns) {
for($x = 0, $l = count($searchColumns); $x < $l; $x++){
if($searchOperators[$x] == 'in') {
$query->whereIn($searchColumns[$x], explode(',', $searchInputs[$x]));
} else if($searchOperators[$x] == 'like') {
$query->where($searchColumns[$x], 'LIKE', "%{$searchInputs[$x]}%");
}
else {
$query->where($searchColumns[$x], $searchColumns, $searchInputs[$x]);
}
}
});
}
return $query->paginate($request->per_page);
}
}
Note: I strongly recommend use post verb for this search page or your data will be html encoded and your url is absolutely not user friendly.
Edited Answer
I have changed the code for multiple columns, single operator and single field.
public function scopeSearchPaginateAndOrder($query)
{
$request = app()->make('request');
$searchInput = $request->get('search_input');
$searchOperator = $request->get('search_operator');
$searchColumns = $request->get('search_column', []);
$query->orderBy($request->column, $request->direction);
if(count($searchColumns) > 0) {
$query->where(function($query) use ($searchInput, $searchOperator, $searchColumns) {
for($x = 0, $l = count($searchColumns); $x < $l; $x++){
if($searchOperator == 'in') {
$query->whereIn($searchColumns[$x], explode(',', $searchInput));
} else if($searchOperator == 'like') {
$query->where($searchColumns[$x], 'LIKE', "%{$searchInput}%");
}
else {
$query->where($searchColumns[$x], $searchOperator, $searchInput);
}
}
});
}
return $query->paginate($request->per_page);
}
