php mysql script not working - php

Question

I got my script working for one column of data but I am trying to send it other data to a second column in mysql table. Here's my php code:
<?php
function db_connect()
{
$hostname = '127.0.0.1';
$db_user = 'root';
$db_password = '';
$db_name = 'hit';
mysql_connect ($hostname, $db_user, $db_password) or die (mysql_error());
echo "Success.. Connected to MySQL...<br />";
mysql_select_db($db_name) or die(mysql_error());
echo "Success.. Connected to Database...<br /> ";
}
function insertData($DATA)
{
function insterData($DATA2)
{
db_connect();
$requete = "INSERT INTO data SET col_Data='".$DATA."'";
if(!mysql_query($requete))
echo mysql_error();
else
echo 'data accepted.';
$requete2 = "INSERT INTO data SET col_Data2='".$DATA2."'";
if(!mysql_query($requete2))
echo mysql_error();
else
echo 'data accepted.';
}
if(isset($_GET['DATA']))
if(isset($_GET['DATA2']))
}
insertData($_GET['DATA']);
insertData($_GET['DATA2']);
}
else
{
echo 'Nop';
}
?>
This is how I send the post data
http://localhost/hit.php?DATA=iamwicked&DATA2=iamcool
This then suppose to send DATA=iamwicked goes into database hit table data column col_data
This then suppose to send DATA2=iamcool goes into database hit table data column col_data2
But I get this error,
but there are errors can someone help me debug.
Here is a working script:
<?php
function db_connect()
{
$hostname = '127.0.0.1';
$db_user = 'root';
$db_password = '';
$db_name = 'hit';
mysql_connect ($hostname, $db_user, $db_password) or die (mysql_error());
echo "Success.. Connected to MySQL...<br />";
mysql_select_db($db_name) or die(mysql_error());
echo "Success.. Connected to Database...<br /> ";
}
function insertData($DATA)
{
db_connect();
$requete = "INSERT INTO data SET col_Data='".$DATA."'";
if(!mysql_query($requete))
echo mysql_error();
else
echo 'data accepted.';
}
if(isset($_GET['DATA']))
{
insertData($_GET['DATA']);
}
else
{
echo 'Nop';
}
?>
this is a working script when I use this url to post data
localhost/hit.php?DATA=iamwicked
When I use this it save iamwicked in database hit table data column col_data
so how do I fix my script to send more data to col_data2 and so forth

Answer 1

Return $conn connection resource #id from function
<?php
function db_connect()
{
$hostname = '127.0.0.1';
$db_user = 'root';
$db_password = '';
$db_name = 'hit';
$conn = mysql_connect ($hostname, $db_user, $db_password) or
die (mysql_error());
echo "Success.. Connected to MySQL...<br />";
mysql_select_db($db_name) or die(mysql_error());
echo "Success.. Connected to Database...<br /> ";
return $conn;
}
$conn = db_connect();
To insert single field
function insertData($DATA)
{
$requete = "INSERT INTO data SET col_Data='".$DATA."'";
mysql_query($requete) or die(mysql_error());
}
if(isset($_GET['DATA'])) {
insertData($_GET['DATA']);
}
if(isset($_GET['DATA2'])) {
insertData($_GET['DATA2']);
}
UPDATE
To insert multiple fields
function insertData($DATA, $DATA2)
{
$requete = "INSERT INTO data SET col_Data='".$DATA."', col_Data2='".$DATA2."'";
mysql_query($requete) or die(mysql_error());
}
if(isset($_GET['DATA']) && isset($_GET['DATA2'])) {
insertData($_GET['DATA'], $_GET['DATA2']);
}
?>

I think you have an wrong spelling here:
function insertData($DATA2) instead of function insterData($DATA2);

Answer 3

There are indeed two problems here.
function insertData($DATA)
{
function insterData($DATA2)
{
What are you trying to achieve here? Declaring a function inside another function is totally useless (and generates errors since it's not allowed). If you want to call a function inside another one you must declare them separately and then call them, f.e.
function insertData($DATA)
{
insterData($somevariable);
//Rest of the operations
}
This should be clear enough. There is another error though.
if(isset($_GET['DATA']))
if(isset($_GET['DATA2']))
}
insertData($_GET['DATA']);
insertData($_GET['DATA2']);
}
else
{
echo 'Nop';
}
I suppose there is a typo here, and you meant
if(isset($_GET['DATA2']))
{
