Insert Data From a Form Into a Database - not working???


Recommended Posts

I have a piece of code that creates the database named stu_db and a table named student with the fields name, idNumber and mark.

 

Ive already got a form to retrieve the data but when i try to put the code below it wont put the data into the database.

 

any advice?

 

CODE TO SEND THE DATA TO THE DATABASE:

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

$sql="INSERT INTO Persons (FirstName, LastName, Age)
VALUES
('$_POST[firstname]','$_POST[lastname]','$_POST[age]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "1 record added";

mysql_close($con)
?>

 

THIIS IS THE CODE WITH THE FORM AND CREATE DATABASE:

Shouldn't you be inserting NAME, ID_NUMBER, and MARK from these fields:

 

            

 

AND NOT:

 

('$_POST[firstname]','$_POST[lastname]','$_POST[age]')";

 

I don't even see these input fields anywhere...

sorry, i didn't have the time to change the code i copied. i did try and type the name of the tables in the database and not the form fields. ill see if this works.

 

do i put this code below the create database php code??? like this?

 

<?php
$con = mysql_connect("localhost","root","20247640");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

// Create database
if (mysql_query("CREATE DATABASE stu_db",$con))
  {
  echo "Database created";
  }
else
  {
  echo "Error creating database: " . mysql_error();
  }

// Create table
mysql_select_db("stu_db", $con);
$sql = "CREATE TABLE student
(
name varchar(30),
idNumber int( NOT NULL,
mark int
)";

// Execute query
mysql_query($sql,$con);

mysql_close($con);


mysql_select_db("my_db", $con);

$sql="INSERT INTO Persons (FirstName, LastName, Age)
VALUES
('$_POST[firstname]','$_POST[lastname]','$_POST[age]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "1 record added";

mysql_close($con)
?>

I'm confused, your form tells me that you want to insert Student data, not Person data.  Here is your table structure that YOU created (and assume you want to use):

 

$sql = "CREATE TABLE student
(
name varchar(30),
idNumber int( NOT NULL,
mark int
)";

 

So your query has the wrong names (I have no clue where the table Persons came from, along with its fields  ???).

 

The INSERT query should be this:

 

$sql="INSERT INTO student (name, idNumber, mark)
VALUES
('{$_POST['NAME']}','{$_POST['ID_NUMBER']}','{$_POST['MARK']}')";

im still getting that error - Error: Incorrect integer value: '' for column 'idNumber' at row 1

 

<?php
$con = mysql_connect("localhost","root","20247640");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

// Create database
if (mysql_query("CREATE DATABASE stu_db",$con))
  {
  echo "Database created";
  }
else
  {
  echo "Error creating database: " . mysql_error();
  }

// Create table
mysql_select_db("stu_db", $con);
$sql = "CREATE TABLE student
(
name varchar(30),
idNumber int( NOT NULL,
mark int
)";

mysql_select_db("stu_db", $con);

[b]$sql="INSERT INTO student (name, idNumber, mark)
VALUES
('{$_POST['NAME']}','{$_POST['ID_NUMBER']}','{$_POST['MARK']}')";[/b]

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "1 RECORD ADDED";

// Execute query
mysql_query($sql,$con);

mysql_close($con);
?>

$sql="INSERT INTO student (name, idNumber, mark)
VALUES
('{$_POST['NAME']}','{$_POST['ID_NUMBER']}','{$_POST['MARK']}')";

echo $sql; // add this line and post it

 

The error is saying that the $_POST['ID_NUMBER'] is blank, not sure why...
