Get html form values and convert to Json array Laravel

Question

I have a form like this in my view:

<form action="http://localhost/RenderForm/public/handle-form" method="POST">
    <input type="hidden" name="_token" value="BOwsdSS3Zc4oI08wDutUQbvtQhGvGZXBgxaOoOFD">                                                                    
    <div class="links">
        <div>
	        First Name:<br>
	        <input name="firstName" type="text">
        </div>        
        <br>
    </div>
                                                
    <div class="links">
        <div>
	        Last Name:<br>
	        <input name="lastName" type="text">
        </div>        
        <br>
    </div>
                                                
    <div class="links">
        <div>
	        Location:<br>
	        <select name="location">
				<option value="0">HN</option>
				<option value="1">HCM</option>
			</select>
        </div>        
        <br>
    </div>
                                            
    <div>
        <button type="submit">Reset Form</button>
        <button type="submit">Complete Task</button>
    </div>
</form>

In my controller, I use $request->all() to get all form values and store into a variable. After that, I use json_encode to convert it become a Json object.
When I debug that variable, it have values:

"{"firstName":"hao","lastName":"nguyen","location":"0"}"

But what I really need is:

[ { "id" : "firstName", "value" : "hao" }, { "id" : "lastName", "value" : "nguyen" }, { "id" : "location", "value" : "0" } ]

Can you tell me how to fix this? Thank you very much!

Try $arr = [json_decode(json_encode($request->all()), true)]; — Dev

Use foreach loop and customised all inputs like this :

$collect = []; // empty array for collect customised inputs

foreach($request->all() as $input_key => $input_value){ // split input one by one

     $collect[] = array( //customised inputs
            "id" => $input_key,
            "value" => $input_value

     );
} 

$result = json_encode($collect); //convert to json
