Hello,
I want to make a database to collect the data from the rfid reader.
My problem: i want to use the $_POST so all the data to be hide from the url.
I have make from the html (for check ) if working and it is working fine when you press the Submit button, now the arduino it self how to press the submit button it self ?
here is the code from the send html
<html>
<title>Manual add rfid card</title>
<head>
<H3><center>Manual add a new rfid card to database.</center></h3>
<hr>
<a href="rfidmain.html" >Return to main page</a>
<form method="POST" action="Ard_Temp_Insert.php">
Card number: <input type="text" name="Card_Number" />
Reader ID: <input type="text" name="Reader_ID"/>
Press button for save data to the database. <input type="submit" name="Save" />
</form>
</head>
</html>
And the code from receive PHP
<?php
function get_val ( $val )
{
return $_POST[$val];
}
$Card_Number = get_val('Card_Number');
if ( $Card_Number == '' )
{
echo "<font color=red><b>Wrong Card_Number !!!</b></font>";
exit;
}
$Reader_ID = get_val ('Reader_ID');
if ( $Reader_ID == '' )
{
echo "<font color=red><b>Wrong Reader_ID !!!</b></font>";
exit;
}
echo(date_default_timezone_set("Europe/Athens"));
$time = date ("H:i:s");
$date = date ("j-n-Y");
$con = mysql_connect("localhost","user","password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("arduino_database", $con);
mysql_query("INSERT INTO rfid_card_log (Card_Number, Reader_ID, Date, Time)
VALUES ('$Card_Number', '$Reader_ID','$date','$time')");
mysql_close($con);
?>
<html>
<center><h3>New record added!</h3></center>
<meta http-equiv="Refresh" content="2;url=http://localhost/rfid_add.html" />
</html>
The piece of code that i want to send from the Arduino is:
Card number:
** Reader ID: **
** Press button for save data to the database. **
But how can i do submit automatically ?
Thank you in advance.
