Let me show you where I'm at now...
My form:
When I click submit it adds to the database (the last entry shown here):
There does seem to be something in the image field... does this mean the image upload worked?
If so, how on earth do I display this image in my blog post as intended? The blog updates perfectly (http://stephengreig.co.uk/newjack/blog.php) but how do I include the image that was uploaded in the blog post?
My PHP code is:
<?php
/* user config variables */
$max_items = 5; /* max number of news items to show */
/* make database connection */
require_once('config.php');
$db = mysql_connect (DB_HOST,DB_USER,DB_PASSWORD);
if(!$db) {
die('Failed to connect to server: ' . mysql_error());
}
mysql_select_db (DB_DATABASE,$db);
function displayNews($all = 0) {
/* bring in two variables
* $db is our database connection
* $max_items is the maximum number
* of news items we want to display */
global $db, $max_items;
/* query for news items */
if ($all == 0) {
/* this query is for up to $max_items */
$query = "SELECT id,title,newstext," .
"DATE_FORMAT(postdate, '%H:%i, %D %M %Y') as date " .
"FROM news ORDER BY postdate DESC LIMIT $max_items";
} else {
/* this query will get all news */
$query = "SELECT id,title,newstext," .
"DATE_FORMAT(postdate, '%H:%i, %D %M %Y') as date " .
"FROM news ORDER BY postdate DESC";
}
$result = mysql_query ($query);
while ($row = mysql_fetch_assoc ($result)) {
/* display news in a simple table */
echo "<div class='newspost'>\n";
/* place table row data in
* easier to use variables.
* Here we also make sure no
* HTML tags, other than the
* ones we want are displayed */
$date = $row['date'];
$title = htmlentities ($row['title']);
$news = nl2br (strip_tags ($row['newstext'], '<a><b><i><u>'));
/* display the data */

/* get number of comments */
