se me ocurre esto para el primer error, quedo atento

Código PHP:

<?php
$stock_sql="SELECT stock.stockID, stock.name, stock.topline, category.name AS catname FROM stock JOIN category ON stock.categoryID=category.categoryID Where stock.categoryID=".$_GET['categoryID'];
 
$stock_query = mysqli_query($id,$stock_sql)or 
die("error de conexion".mysqli_error($id));
 
$stock_query = mysqli_query($id,$stock_sql)
if(!$stock_query){
    die('Error de conexion'.mysqli_error($id));
}
 
 
$stock_rs=mysqli_fetch_assoc($stock_query);
?>
