Question

I am having a problem with my php code, it is not pulling my table row from mysql database. Does this code look correct.

<?php

$host="localhost"; // Host name 
$username="username"; // Mysql username 
$password="password"; // Mysql password 
$db_name="database"; // Database name 
$tbl_name="marquee"; // Table name

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// Retrieve data from database 
$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);
?>

    <?php
// Start looping rows in mysql database.
$rows=mysql_fetch_array($result);
?>
test
<? echo $rows['scroll']; 
   echo $rows['id'];
?>

Answer 1

Change your code to this, and try again.

$host="localhost"; // Host name 
$username="username"; // Mysql username 
$password="password"; // Mysql password 
$db_name="database"; // Database name 
$tbl_name="marquee"; // Table name

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die (mysql_error()); 
mysql_select_db("$db_name")or die(mysql_error());

// Retrieve data from database 
$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);

while($rows=mysql_fetch_array($result)) { echo "$rows[scroll] $rows[id]";} ?>

For updating row through html form

Below, is the code to update but, you must post $new_value and $id first so, sql know which one to update.

$result = mysql_query("UPDATE marquee SET scroll='$new_value' WHERE id='$id'")
or die(mysql_error());

For the above code, you should use html form to send values like:

<form method="" post="">
<input type="text" name="new_value" />
<input type="text" name="id" />
<input type="submit" name="submit" />

The above to code + the passing of variables are all you need to update that table
