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?

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
