how can i check for empty array inside request variable in laravel?

Question

Code:

public function specificationsave(Request $request) {   
    if (!empty($request->product_id)) {
        if (empty($request->specificationkeys) && empty($request->specificationvalues)) {
            return response()->json(["message" => 'Empty form submitted'], 202);
        } else {
            // something code 
        }
    } else {
        return response()->json(["message" => 'something went wrong with product'], 403);
    }
}

Form code:

<input type="text" name="specificationkeys[]"/>
<input type="text" name="specificationvalues[]"/>

Problem:

When I am putting empty condition on my specificationkeys array it is not working, because my key has a empty array so I can i check that the key has array or not or as I want empty check without validator because fields are not mandatory.

show us dd($request->specificationkeys) and dd($request->specificationvalues) — Sohel0415

for example product_id is return as array check condition like this

if($request->product_id && is_array($request->product_id) && count($request->product_id) > 0) {
     //success validation
}else {
    //failed validation 
}

use simple count function for this.

 if (count($request->specificationkeys) == 0 && count($request->specificationvalues) == 0){
     //your logic for empty
  }else{
    //Your logic for not empty  
 }

Try this:

public function specificationsave(Request $request) {   
    if (isset($request->product_id) && !empty($request->product_id)) {
        if (is_array($request->specificationkeys) && 
            count($request->specificationkeys) !== 0 && 
            is_array($request->specificationvalues) && 
            count($request->specificationvalues) !== 0) {
            return response()->json(["message" => 'Empty form submitted'], 202);
        } else {
            // something code 
        }
    } else {
        return response()->json(["message" => 'something went wrong with product'], 403);
    }
}
