PHP - Improving Website

Hi, I'm trying to improve my search so that it searches all words that i write in the search box and matches keywords

my code right now is
Code: [Select]

<?php
$sub = $_GET['article'];

echo "<h2>search results for: $sub</h2><br><br>";


$sub = str_replace(" ", "%", $sub);

$alb =  mysql_connect("localhost", "", "") or die(mysql_error());  
mysql_select_db("articles") or die(mysql_error()); 

mysql_set_charset('utf8', $alb); 

$query2 = "SELECT * FROM `blog` WHERE `title` like '%$sub%'";
$result2 = mysql_query($query2) or die(mysql_error());


while ($postede2 = mysql_fetch_assoc($result2))
{
$title = "{$postede2['title']}";
$author = "{$postede2['author']}";
$section = "{$postede2['section']}";
$description = "{$postede2['description']}";
$url = "{$postede2['url']}";

echo "<a href='$url'><h3><b>$title</b></h3></a><br>";
echo "By $author, Category: $section<br>";
echo "$description ...<br><br>";

}
?>
How do i break down the search even further?

I'm trying to figure out how I can reduce as much functionality as possible and still keep it doing what it needs to do. What I mean by functionality is the number of queries being performed or any of the other code for that matter. I do show at the bottom of my post what I have so far, however that doesn't cover all the queries.

Hello,

My upload script is working for the most part and while I know that I need a couple of little fixes and will need help with those I also wouldn't mind some tips on how I could have written it better in the first place.

The 2 problems I am having.
1. If the copy image fails the script doesn't and still creates a database entry. I would like to stop it from doing that but can't seem to work it out.
2. My mate is getting file type errors even though he is trying to upload small .jpg files. I can't seem to recreate the problem. Maybe someone can see something that might be problematic??

I am using this a modal window(jBox) - with a web Form in it, that requires the Form (just Name & Email) to be completed and Submitted in order to close the modal window - allowing access to the main page.

The Form uses this corresponding ../submit.php which this:

if (empty($_POST['name'])|| empty($_POST['email'])){
$response['success'] = false;
} else {
$response['success'] = true;
}

echo json_encode($response);

where, upon Form > submit, successfully shows 'error' if the Form fields are not populated, and 'success' when the Form fields are populated/submitted.

I'd like the Form to require a proper/valid email address and avoid spam and header injection
(maybe honeypot protection and implement a form of rate limiting (a single ip may not send more than x messages per day)).

Any assistance/guidance is appreciated
