you need to have the database name among the parameters for connection, how else would the script know where to find the data you want to extract from the database? :)

apart for lacking database name I think you got it right, that is if you created a databse user with the name acellec through cpanel and connected that to the database with privileges needed :)

$username = "acellec_acellec"; // MySQL Username

I think there is a problem here. This looks like a database user name. When I do my mysql_connect statements, for $username I just my userid.

localhost is just that, localhost.

here is my connect statement that I used when I experimented with forms to enter the data. $id is just my hosting id that I use to log into cpanel, same for the password.

$id = $_POST["id"];
$pwd = $_POST["pwd"];
$server = "localhost";

$con = mysql_connect($server, $id, $pwd);


p.s. I hope your actual password is different from what it says in your error message.

p.s.s. Lady_Anna wirt your comment

you need to have the database name among the parameters for connection, how else would the script know where to find the data you want to extract from the database?

correct me if I am mistaken, but isn't your database name specified in the mysql_select_db statement and not the mysql_connect statement?

all scripts I've encountered has that as part of the setup and initial connect... but it is possible it could be done using mysql_select_db as well

ok cool, learn something every day!

fwiw, I learned from the php/MYSQL tutorial that is in the tutorials section of this forum, where database name is specified in the mysql_select_db as opposed to the connect.

i have this code

PHP: 
<?
    $DBConnect = mysqli_connect("localhost", "acellec", "francisco2");
    $DBConnect->select_db("acellec_AutomobileParts");
    
    $QueryResult = $DBConnect->query($SQLstring)
            Or die("<p>Unable to execute the query.</p>"."<p>Error code ". $DBConnect->errno . ": " . $DBConnect->error) . "</p>";
?>

is this the correct way? how come i still have this error

select_db("acellec_AutomobileParts"); $QueryResult = $DBConnect->query($SQLstring) Or die(" Unable to execute the query.
"." Error code ". $DBConnect->errno . ": " . $DBConnect->error) . "
"; ?>

The error is in your $SQLstring, probably. Could you post that?

hello this is the code..

this is called list.php

PHP: 
<body>

<?
$TableName = "automobileparts";
$SQLstring = "SELECT * acellec_automobileparts";

require_once("dbconnect.php");
        
echo "<table width='100%' border='1'>";
$Row = $QueryResult->fetch_row();
do {
        //echo "<tr><td>{$Row[0]}</td>";
        echo "<tr>";
        echo "<td align='right'>{$Row[1]}</td>";
        echo "<td align='right'>{$Row[2]}</td>";
        echo "<td align='right'>{$Row[3]}</td>";
        echo "<td align='right'>{$Row[4]}</td>";
        echo "<td align='right'>{$Row[5]}</td>";
        echo "</tr>";
        $Row = $QueryResult->fetch_row();
} while ($Row);
echo "</table>";



$DBConnect->close();


?>

</body>
and my code for the connection is this

PHP: 
<?
    $DBConnect = mysqli_connect("localhost", "acellec", "francisco2");
    $DBConnect->select_db("acellec_AutomobileParts");
    
    $QueryResult = $DBConnect->query($SQLstring)
            Or die("<p>Unable to execute the query.</p>"."<p>Error code ". $DBConnect->errno . ": " . $DBConnect->error) . "</p>";
?>
now my problem is displaying it how come i cannot

error is

fetch_row(); do { //echo "{$Row[0]}"; echo ""; echo "{$Row[1]}"; echo "{$Row[2]}"; echo "{$Row[3]}"; echo "{$Row[4]}"; echo "{$Row[5]}"; echo ""; $Row = $QueryResult->fetch_row(); } while ($Row); echo ""; $DBConnect->close(); ?>

Code: 
$SQLstring = "SELECT * acellec_automobileparts";

Needs to be

Code: 
$SQLstring = "SELECT * FROM acellec_automobileparts";

You can also simplify your while loop:

Code: 
while($row = $QueryResult->fetch_row()) {
....}

And it's also important to make sure you have a valid result before trying to use fetch_result:

Code: 
if (!$QueryResult) {
die("Query Failed!"); }

PHP: 
<body>
<h1>Address Book</h1>
<p><a href="insert.php">Insert Data</a></p>
<?
$TableName = "automobileparts";
$SQLstring = "SELECT * FROM automobileparts";

require_once("dbconnect.php");
        
echo "<table width='100%' border='1'>";
$Row = $QueryResult->fetch_row();
do {
        //echo "<tr><td>{$Row[0]}</td>";
        echo "<tr>";
        echo "<td align='right'>{$Row[1]}</td>";
        echo "<td align='right'>{$Row[2]}</td>";
        echo "<td align='right'>{$Row[3]}</td>";
        echo "<td align='right'>{$Row[4]}</td>";
        echo "<td align='right'>{$Row[5]}</td>";
        echo "<td align='right'><a href=\"edit.php?id={$Row[0]}\">Edit</a></td>";
        echo "<td align='right'><a href=\"delete.php?id={$Row[0]}\">Delete</a></td>";
        echo "</tr>";
        $Row = $QueryResult->fetch_row();
} while ($Row);
echo "</table>";



$DBConnect->close();


?>

That's a code fragment, not an error. What's the error message you're getting?

Double check your table name. You've listed two different ones now.

Check that your user has privileges on the table as well. Go to CPanel->Mysql Databases and at the bottom of the page it will show who can access what.
