I have a simple form (main.php) which takes input as a Phone no. of the customer:
    <!DOCTYPE HTML>
   <html>
      <div style=margin:0 auto align=center >
       <form action = "options.php" method = "get" />
          <p> <h3>Enter Phone Number:</h3> <input type = "text" name = 
                                    "cust_phone" />
          <p> <input type = "submit" value = "Submit" />
       </form>
      </div>
   </html>
The no. entered is checked in the Oracle DB and if a customer is present with the no. then information regarding that customer is displayed else a new customer is added with the phone no. (options.php)
     <!DOCTYPE HTML>
    <html>
      <body> Details of:<?php echo htmlentities($_GET["cust_phone"])."<br>";

     $link = oci_connect('hd', 'hd', 'localhost/mydb');
     if(!$link)
        {       
            $e = oci_error();
            exit('Connection Error' . $e['message']);
        }
    $query = "select cust_id from customer where cust_phone = :ph_bv";
    $stid = oci_parse($link,$query);
    $ph = htmlentities($_GET["cust_phone"]);
    oci_bind_by_name($stid, ':ph_bv', $ph);
    oci_execute($stid);
    $row = oci_fetch_array($stid, OCI_ASSOC);
    if(!$row)
    {
        exit("Person Not Found");
    }
    $cust_id = $row["ID"];
    oci_free_statement($stid);
?>
    <table border = "black" />
        <tr> 
            <th> ADDRESS </th>
            <th> AREA </th>
        </tr>
    <?php
        $query1 = "select a.address, a.area from customer c 
              join customer_address ca on c.cust_id = ca.cust_id
              join address a on a.address_id = ca.address_id where cust_id = :id_bv";
        $stid1 = oci_parse($link, $query1);
        oci_bind_by_name($stid1, ":id_bv", $cust_id);
        oci_execute($stid1);
            while($row = oci_fetch_array($stid1))
            {
              echo "<tr><td>" . htmlentities($row["ADRESS"]) . "</td>";
              echo "<td>" . htmlentities($row["AREA"]) . "</td></tr>";
            }
             oci_free_statement($stid1);
             oci_close($link);
         ?>
         </table>
          </body>
        </html>
The first part of the code works fine and it displays the message "Person Not Found". However the second part gives error:
Details of: 9711210000

      ( ! ) Notice: Undefined index: ID in 
            E:\xampp\htdocs\myfiles\options.php on line 24

I have two questions:
1. Instead of "person not found", I want to add a new customer in my DB?

2. How to resolve these errors? I am new to PHP and this is just my first code. Any help appreciated.

>where cust_id = :id_bv";
line above needs table alias so Oracle knows from which table the column (cust_id) should taken.

BTW, you should always test every SQL statement using sqlplus to validate that it produces the desired result set.

Yeah this was the only one statement which I did not check. BTW I am still getting the "Undefined INDEX: ID" error.

Do not tell, copy and paste what you do and get.
And number your lines so we can see which one/s is/are involved.

>$cust_id = $row["ID"];
I suspect that error comes from line above

How do I resolve it? I want to store the result of a query in a variable and use it to find the details of that cust_id. In this case ther will only be one value returned, but what if there are more than one value? How do I store the value in a variable? What is "ID" in $rows["ID"]? Is it a column name from my database?

Think a little bit, where does $row come from? How is it set?
