I'm in a bit of a pickle with freshening up my PHP a bit, it's been about 3 years since I last coded in PHP. Any insights are welcomed! I'll give you as much information as I possibly can to resolve this error so here goes!
Files
- config.php
- database.php
- news.php
- BLnews.php
- index.php
Includes
- config.php -> news.php
- database.php -> news.php
- news.php -> BLnews.php
- BLnews.php -> index.php
Now the problem with my current code is that the database connection is being made but my database refuses to be selected. The query I have should work but due to my database not getting selected it's kind of annoying to get any data exchange going!
database.php
<?php
class Database {
//-------------------------------------------
// Connects to the database
//-------------------------------------------
function connect() {
if (isset($dbhost) && isset($dbuser) && isset($dbpass)) {
$con = mysql_connect($dbhost, $dbuser, $dbpass) or die("Could not connect: " . mysql_error());
}
}// end function connect
function selectDB() {
if (isset($dbname) && isset($con)) {
$selected_db = mysql_select_db($dbname, $con) or die("Could not select test DB");
}
}
} // end class Database
?>
News.php
<?php
// include the config file and database class
include 'config.php';
include 'database.php';
...
?>
BLnews.php
<?php
// include the news class
include 'news.php';
// create an instance of the Database class and call it $db
$db = new Database;
$db -> connect();
$db->selectDB();
class BLnews {
function getNews() {
$sql = "SELECT * FROM news";
if (isset($sql)) {
$result = mysql_query($sql) or die("Could not execute query. Reason: " .mysql_error());
}
return $result;
}
?>
index.php
<?php
...
include 'includes/BLnews.php';
$blNews = new BLnews();
$news = $blNews->getNews();
?>
...
<?php
while($row = mysql_fetch_array($news))
{
echo '<div class="post">';
echo '<h2><a href="#"> ' . $row["title"] .'</a></h2>';
echo '<p class="post-info">Posted by <a href="#"> </a> | <span class="date"> Posted on <a href="#">' . $row["date"] . '</a></span></p>';
echo $row["content"];
echo '</div>';
}
?>
Well this is pretty much everything that should get the information going however due to the mysql_error in $result = mysql_query($sql) or die("Could not execute query. Reason: " .mysql_error());
I can see the error and it says:
Could not execute query. Reason: No database selected
I honestly have no idea why it would not work and I've been fiddling with it for quite some time now. Help is most welcomed and I thank you in advance!
