I need to read json data inside an array. Please help correct my code.. i am trying to do an API.

Yes, definitely needs to be cleaned up.

  • Do not directly insert user provided values in the DB but use prepared statements.
  • You don't want to use else if for all your validation but just an if since you are adding the errors to an array.
  • You could shorten the script which assigns values by using $CONTACT_ID=$request['CONTACT_ID']??null;
  • Break your code into several small functions.

i also have another issue in inserting multiple arrays at the same call.

This is how my json data will look like,

Below is my code.But it is only storing array value at position [0] since i have hard coded here, How to loop and store all the values. Please guide me, Thank you in advance.

	$SHIP_SERIAL_NO=isset($request['shipment_data'][0]['SHIP_SERIAL_NO'])??null; 
	$MASTER_NO=isset($request['shipment_data'][0]['MASTER_NO'])??null; 
	$HOUSE_NO=isset($request['shipment_data'][0]['HOUSE_NO'])??null; 
	$shipment_data=isset($request['shipment_data'])?$request['shipment_data']:""; // this is ab array

Run the following script and spend time to understand it.  If you don't understand <<<EOL, see https://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc.  If you don't understand how the functions work, look them up on php.net.

<?php
ini_set('display_errors', 1);

$json = <<<EOL
{
    "CONCACT_ID": 123,
    "shipping_data": [{
            "SER_NO": 312,
            "BLA": 123
        }, {
            "SER_NO": 112,
            "BLA": 223
        }
    ]
}
EOL;
echo($json.PHP_EOL);

// Turn the JSON string into either an array or object (I use an array)
$arr = json_decode($json, true);
print_r($arr);
$obj = json_decode($json, false);
print_r($obj);

printf('array: %s object: %s'.PHP_EOL, $arr['CONCACT_ID'], $obj->CONCACT_ID);

foreach($arr['shipping_data'] as $item) {
    print_r($item);    
}

foreach($obj->shipping_data as $item) {
    print_r($item);    
}

Thank you so much @NotionCommotion!

That was a helpful document.

 

Resolved with the below query

						foreach($request['shipment_data'] as $item) {
						$SHIP_SERIAL_NO= ($item['SHIP_SERIAL_NO']);    
						$MASTER_NO= ($item['MASTER_NO']);    
						$HOUSE_NO= ($item['HOUSE_NO']);   

			$stid_2 = oci_parse($conn, "Insert into FL_SHIPMENT_DATA (CONTACT_ID,INV_SERIAL_NO,SHIP_SERIAL_NO,MASTER_NO,HOUSE_NO) Values ('$CONTACT_ID','$INV_SERIAL_NO','$SHIP_SERIAL_NO','$MASTER_NO','$HOUSE_NO')");
			oci_execute($stid_2);
																	}

foreach() is good.

Have you considered PDO (an OCI driver is available)?

$curl_data = '{
       "CONTACT_ID": "1793",
       "INV_SERIAL_NO": "345",
       "shipment_data": [
           {
            "SHIP_SERIAL_NO": "11",
            "MASTER_NO": "11",
            "HOUSE_NO": "11"
           },
           {
            "SHIP_SERIAL_NO": "22",
            "MASTER_NO": "22"
           },
           {
            "SHIP_SERIAL_NO": "33",
            "HOUSE_NO": "33"
           }
       ]
}';

$request = json_decode($curl_data, 1);
$base = [     "CONTACT_ID" => $request['CONTACT_ID'],
              "INV_SERIAL_NO" => $request['INV_SERIAL_NO'],
              "SHIP_SERIAL_NO" => null,
              "MASTER_NO" => null,
              "HOUSE_NO" => null
            ];

$stmt = $db->prepare("INSERT INTO fl_shipment_data (contact_id, inv_serial_no, ship_serial_no, master_no, house_no)
                      VALUES (:CONTACT_ID, :INV_SERIAL_NO, :SHIP_SERIAL_NO, :MASTER_NO, :HOUSE_NO)
                     ");

foreach ($request['shipment_data'] as $ship) {
    $data = array_merge($base, $ship);
    $stmt->execute($data);
}

results

fl_shipment_data
+----------------+------------+---------------+----------------+-----------+----------+
| fl_shipment_id | contact_id | inv_serial_no | ship_serial_no | master_no | house_no |
+----------------+------------+---------------+----------------+-----------+----------+
|              1 |       1793 |           345 |             11 |        11 |       11 |
|              2 |       1793 |           345 |             22 |        22 |     NULL |
|              3 |       1793 |           345 |             33 |      NULL |       33 |
+----------------+------------+---------------+----------------+-----------+----------+

@Abrar  If only your friends are using your application and they will not mind if their identity gets stolen and their bank accounts emptied, I guess it is okay to do it as you are, but if you developing your application for others, please do what Barand suggested and use PDO and prepared statements.

Thank you so much for the suggestions. I am preparing this application for others so we need to consider the security parameters. i will follow Barand suggestion and will use PDO and prepared statements.

 

Thank you once again for your support..
