Retrieve the value of a PHP variable and dynamically add it to a query

There is a way to achieve this using the Laravel framework. Below is a snippet of code that demonstrates how to dynamically create where clauses:

$keywords = ProductKeyword::orderBy('name', 'asc')->pluck('name')->toArray();
if (!empty($keywords)) {
    $str = '';
    foreach ($keywords as $key => $keyword) {
        if ($key == 0) {
            $str .= "Where('description', 'like', '%' . $keyword . '%')";                    
        } else {
            $str .= "->orWhere('description', 'like', '%' . $keyword . '%')";
        }
    }
}
$str .= "->all()";

$items = Item::$str;
dd($items);

In order for the value of $str to be appended to the Item model, you can modify the code as follows:

$items = Item::Where('description', 'like', '%' . 'laptop' . '%')->orWhere('description', 'like', '%' . 'pc' . '%')->all();

This will provide you with the ability to dynamically create where-clauses in your application.

Don't overthink it too much. Simply gather all the keywords, loop through them, and use orWhere() on the keyword name. That's it! Start by creating a query for your items using the query() method, then add orWhere() inside a loop for each keyword. Laravel will take care of everything else. Finally, just call get() to retrieve your data!

$keywords = ProductKeyword::orderBy('name', 'asc')->get();

$items = Item::query();
foreach ($keywords as $key => $keyword) {
    $items->orWhere('description', 'like', '%'.$keyword->name.'%');
}

$items = $items->get();
dd($items);

Keep in mind that if there are no keywords, the code will essentially be equivalent to Item::all(), as no where-clauses are applied.

You're taking a more intricate approach to solve this problem. My solution is very similar to what @Qirel suggested

//set up your query
$query = Item::query();
foreach ($keywords as $keyword) {
   //loop through the keywords in the description column of the Item Table to find matching records and add them to the $query
   $query->orWhere('description', 'like', '%'.$keyword.'%');
}
// retrieve the matched records and store them in the $result variable
$result=$query->get();`enter code here`
