Question

While I am running this code it showing me a following error:-

Column ‘virtuemart_product_id’ in where clause is ambiguous
Can anyone tell me how to resolve it.
Thank you.

<?php
    mysql_connect('localhost','root','');
    mysql_select_db('joom');
    $get=$_GET['virtuemart_product_id'];
    $get1=$_GET['virtuemart_category_id'];
    $sql="SELECT 
            btn9c_virtuemart_products_en_gb.virtuemart_product_id,
            btn9c_virtuemart_products_en_gb.product_s_desc, 
            btn9c_virtuemart_products_en_gb.product_desc, 
            btn9c_virtuemart_products_en_gb.product_name, 
            btn9c_virtuemart_product_prices.product_price 
          FROM btn9c_virtuemart_products_en_gb 
          JOIN btn9c_virtuemart_product_prices ON
            btn9c_virtuemart_products_en_gb.virtuemart_product_id=btn9c_virtuemart_product_prices.virtuemart_product_id 
          WHERE virtuemart_product_id='$get' ";
    if($result=mysql_query($sql))
    {
        while($row=mysql_fetch_assoc($result))
        {
            echo $row['product_price'];
        }
    }
    else 
    {
        echo (mysql_error());
    }       
?>

Put table name (or alias) with column names in where clause which are common between tables you are joining.

Try below:

$sql="SELECT 
        btn9c_virtuemart_products_en_gb.virtuemart_product_id,
        btn9c_virtuemart_products_en_gb.product_s_desc, 
        btn9c_virtuemart_products_en_gb.product_desc, 
        btn9c_virtuemart_products_en_gb.product_name, 
        btn9c_virtuemart_product_prices.product_price 
      FROM btn9c_virtuemart_products_en_gb 
      JOIN btn9c_virtuemart_product_prices ON
        btn9c_virtuemart_products_en_gb.virtuemart_product_id=btn9c_virtuemart_product_prices.virtuemart_product_id 
      WHERE  btn9c_virtuemart_products_en_gb.virtuemart_product_id='$get' ";
