Displaying Information based on entered value in PHP with Oracle Database 11g R2
Question
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

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.

$row don't have the record so you can't access $row["ID"] so first, check if records are there then only access the data.
Second problem is with your query, cust_id field is in two tables so use it with aliases while writing queries.
try with below code:-
<!DOCTYPE HTML>
<html>
<body> Details of:<?php echo htmlentities($_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);
$row = oci_num_rows($stid);
$cust_id ='';
if($row>0)
{
$rows = oci_fetch_array($stid, OCI_ASSOC);
$cust_id = $rows["ID"];
oci_free_statement($stid);
exit("Person Not Found");
}
?>
<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 c.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>
