how to use a user input defined in one html page in another php page to fetch data from oracle database
Question
I have one php page which connects to the oracle database and fetches some data based on some user input. Here in this case Once the user will enter the user_id, and submit it, my code will fetch some more data (REQUEST_TIME,WORKFLOW_NAME,EVENT_MESSAGE) of that user. I am running below code and i am not sure if i am doing it correct. I am getting below error:
Warning: oci_execute(): ORA-00904: "USER_ID": invalid identifier in D:\\SVN\\TOOLBOX_WEB\\WEBContent\\admin\\V2\\public\\ssn\\index2.php on line 36
can someone please guide, how to proceed.
This is my php page:
<pre><?php
include('mypage.php');
class logAgent
{
const CONFIG_FILENAME = "data_config.ini";
private $_dbConn;
private $_config;
function __construct()
{
$this->_loadConfig();
$this->_dbConn = oci_connect($this->_config['db_usrnm'],
$this->_config['db_pwd'],
$this->_config['hostnm_sid']);
}
private function _loadConfig()
{
// Loads config
$path = dirname(__FILE__) . '/' . self::CONFIG_FILENAME;
$this->_config = parse_ini_file($path) ;
}
public function fetchLogs() {
$uid =$_POST["USER_ID"];
$sql = "SELECT REQUEST_TIME,WORKFLOW_NAME,EVENT_MESSAGE
FROM AUTH_LOGS WHERE USER_ID = '".$uid."'";
//Preparing an Oracle statement for execution
$statement = oci_parse($this->_dbConn, $sql);
//Executing statement
oci_execute($statement);
while (($row = oci_fetch_row($statement)) != false) {
foreach ($row as $item) {
echo $item . " ";
}
echo "\n";
}
}
}
?>
mypage.php
<!DOCTYPE html> <html> <head> <title>User_Logs</title> </head> <body> <?php if ($_SERVER["REQUEST_METHOD"] == "POST"){ $uid =$_POST["USER_ID"]; $logAgent = new logAgent(); $logAgent->fetchLogs(); } ?> <form method="POST" id="form-add" action="index2.php"> USER_ID: <input type="text" name="USER_ID"/><br> <input type="submit" name="submit" value="Get_Logs"/> </form> </body> </html>

According to your error, oracle is complaining that it can't find the field USER_ID. Looking at your SELECT statement in the php file, oracle expects that field to be in your AUTH_LOGS table. Check to ensure that you've spelt the name of the field correctly or that the field exists in the table.
