Populating an input type text field, according to previous dropdown selection in form using php & ajax

As the title says, I am trying to populate a text input according to a dynamic drop down list, but I can not get it to work. Below is my form:

<div class="form-group">
    <label for="mealcategorytype"" class="col-12 col-form-label">Meal Category </label>
        <div class="col-12">
           <select class="form-control " name="categ_type" id="mealcategorytype">
            <option  value='' disabled selected>Select Meal Category...</option>
             <?php
               require_once '_db.php';                                         
               $stmt= $db->prepare("SELECT * FROM `rate_type_categories`");                                        
               $stmt->execute();
               $values=$stmt->fetchAll();  
                                                                                               
               foreach($values as $value)
               {                                                
                if($value['rate_type_category_id']==$rowCatRatePlan['rate_type_category_id'])
                {
                 echo 
                '<option selected value="'.$value['rate_type_category_id'].'">'.$value['rate_type_category_name'].'</option>';
                }
                else
                {
                 echo '<option value="'.$value['rate_type_category_id'].'">'.$value['rate_type_category_name'].'</option>';
                }
              }  ?>                 
          </select>
        </div>
   </div>


   <div class="form-group ">
     <label for="example-date-input" class="col-12 col-form-label">Rate Plan Charge Percentage</label>
    <div class="col-12">
     <input class="form-control"  id="ratepercent" name='rate_percentage' type="text" value=''>
    </div>
   </div>

By selecting the required rate type category (you will see it as meal category also in my code ), I want to populate the the next field ( Rate Plan Charge Percentage ) with the selected category's Rate Plan Charge Percentage from the database.

rate type category table in link:

enter image description here

this is the script that I tried using :

$(document).ready(function(){  
      $('#mealcategorytype').change(function(){  
           var mealCategory_id = $(this).val();  
           alert($this);
           $.ajax({  
                url:"match_meal_category_to_rate_plan.php",  
                method:"POST",  
                data:{mealCategoryID:mealCategory_id},  
                success:function(data){  
                     $('#ratepercent').val(data);  
                     //$('#ratedocdesc').html(data);  
                     
                }  
           });  
      });  
 });

and the code in the page where the ajax request will be sent :

$output='';
$getMealCategContent="SELECT * FROM rate_type_categories WHERE rate_type_category_id  = '".$_POST['mealCategoryID']."'  ";
echo $getMealCategContent;
$resultMealCategContent=mysqli_query($conn,$getMealCategContent);

while($rowCategContent=mysqli_fetch_array($resultMealCategContent))
{
  $output.='        
  <input class="form-control"  id="ratepercent" name="rate_percentage" type="text" value="'.$rowCategContent["rate_category_charge_percentage"].'"> ';
}                                 
echo $output;

What am I doing wrong?

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
