PHP search suggestions - php

Question

I have a PHP script which works with jQuery to provide search suggestions. It pulls results from a MySQL database. However, I only want 5 results to display at once for the letter the user has typed but it seems all of the results appear. Why could this be?
My code is:
<p id="searchresults"><?php
$db=new mysqli('localhost','username','password','database');
if(isset($_POST['queryString'])){
$queryString=$db->real_escape_string($_POST['queryString']);
if(strlen($queryString)>0){
$query = $db->query("SELECT * FROM search s WHERE name LIKE '%" . $queryString . "%'");
if($query){
while ($result = $query ->fetch_object()){
echo '<a href="/search/'.$result->name.'/1/">';
$name=$result->name;
echo ''.$name.'';
}
}
}
}
?></p>
I hope you can understand what I am trying to describe.

Answer 1

Change "SELECT * FROM search s WHERE name LIKE '%" . $queryString . "%'"
to "SELECT * FROM search s WHERE name LIKE '%" . $queryString . "%' LIMIT 5"
if you want to limit it to 5 results.

Answer 2

You need to add pagination code to your page:
There is the sample code:
<?php
// Connects to your Database
mysql_connect("your.hostaddress.com", "username", "password") or die(mysql_error());
mysql_select_db("address") or die(mysql_error());
//This checks to see if there is a page number. If not, it will set it to page 1
if (!(isset($pagenum)))
{
$pagenum = 1;
}
//Here we count the number of results
//Edit $data to be your query
$data = mysql_query("SELECT * FROM topsites") or die(mysql_error());
$rows = mysql_num_rows($data);
//This is the number of results displayed per page
$page_rows = 4;
//This tells us the page number of our last page
$last = ceil($rows/$page_rows);
//this makes sure the page number isn't below one, or more than our maximum pages
if ($pagenum < 1)
{
$pagenum = 1;
}
elseif ($pagenum > $last)
{
$pagenum = $last;
}
//This sets the range to display in our query
$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows;
//This is your query again, the same one... the only difference is we add $max into it
$data_p = mysql_query("SELECT * FROM topsites $max") or die(mysql_error());
//This is where you display your query results
while($info = mysql_fetch_array( $data_p ))
{
Print $info['Name'];
echo "<br>";
}
echo "<p>";
// This shows the user what page they are on, and the total number of pages
echo " --Page $pagenum of $last-- <p>";
// First we check if we are on page one. If we are then we don't need a link to the previous page or the first page so we do nothing. If we aren't then we generate links to the first page, and to the previous page.
if ($pagenum == 1)
{
}
else
{
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=1'> <<-First</a> ";
echo " ";
$previous = $pagenum-1;
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$previous'> <-Previous</a> ";
}
//just a space
echo " -- ";
//This does the same as above, only checking if we are on the last page, and then generating the Next and Last links
if ($pagenum == $last)
{
}
else {
$next = $pagenum+1;
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$next'>Next -></a> ";
echo " ";
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$last'>Last ->></a> ";
}
?>
