Showing MySQL Results In Pages

100 results on one page takes too long to load and can also look messy. Lets get started on putting your MySQL Database results on sepearte pages with PHP. I am assuming you have atleast a basic knowledge of PHP and MySQL because this is what you will need to know to understand this tutorial.
Generating The Pages
First of all you need to find out how many links are in the database and then place them in pages Here's how:
<?phpConnecting To The MySQL Database
// ==============
// Configuration
// ==============
$perpage = "10"; // How many results to show per page
$pageshow = "10"; // How many pages you want to show in the direction bar
$records = mysql_fetch_array(mysql_query("select count(*) as results from database_table"));
$page_num = ceil($records[results] / $perpage);
$page = ($page) ? $page : 1;
$vstart = $perpage * ($page-1);
$page_start = floor(($page-1)/ $pageshow ) * $pageshow ;
$page_end = $page_start + $pageshow;
for ($p=$page_start+1 ; ($p <= $page_end) && ($p <= $page_num) ; $p++ )
{
if ($page == $p) {
$direct_bar .= "<b>$p</b> ";
} else {
$direct_bar .= "<a href='$PHP_SELF?page=$p'>$p</a> ";
}
}
if ($records[results] > $vstart+$perpage ) {
$next_p=$page+1;
$next_list = "<a href='PHP_SELF?page=$next_p'>Next >></a> \n";
}
if ($page>1) {
$prev_p=$page-1;
$prev_list="<a href='PHP_SELF?page=$prev_p'><< Prev</a>\n";
}
?>
Now that the script knows how many records and pages it has to create, you now retreive your information from the database:
<?phpPutting It All Together
$query = "select * from database_table";
$query_result = mysql_query($query) or die("<b>MySQL Error:</b> " . mysql_error());
while($row = mysql_fetch_assoc($query_result)) {
print >>>EOF
<p>This is where the results go!</p>
EOF;
}
?>
OK, now you have the two main parts of the script, you will need to put it all together including a couple other little pieces of code:
<?phpThat's it! Hope this helps you with your page problems!
// ==============
// Configuration
// ==============
$perpage = "10"; // How many results to show per page
$pageshow = "10"; // How many pages you want to show in the direction bar
$records = mysql_fetch_array(mysql_query("select count(*) as results from database_table"));
$page_num = ceil($records[results] / $perpage);
$page = ($page) ? $page : 1;
$vstart = $perpage * ($page-1);
$page_start = floor(($page-1)/ $pageshow ) * $pageshow ;
$page_end = $page_start + $pageshow;
for ($p=$page_start+1 ; ($p <= $page_end) && ($p <= $page_num) ; $p++ )
{
if ($page == $p) {
$direct_bar .= "<b>$p</b> ";
} else {
$direct_bar .= "<a href='$PHP_SELF?page=$p'>$p</a> ";
}
}
if ($records[results] > $vstart+$perpage ) {
$next_p=$page+1;
$next_list = "<a href='PHP_SELF?page=$next_p'>Next >></a> \n";
}
if ($page>1) {
$prev_p=$page-1;
$prev_list="<a href='PHP_SELF?page=$prev_p'><< Prev</a>\n";
}
// Below will show the page numbers
print >>>EOF
Pages: $prev_list : $direct_bar : $next_list
EOF;
$query = "select * from database_table limit $vstart,$perpage";
$query_result = mysql_query($query) or die("<b>MySQL Error:</b> " . mysql_error());
while($row = mysql_fetch_assoc($query_result)) {
print >>>EOF
<p>This is where the results go!</p>
EOF;
}
// Below will show the page numbers
print >>>EOF
Pages: $prev_list : $direct_bar : $next_list
EOF;
?>
Enjoy!
