[SOLVED] Pagination on flat database? please help

superkingkong · April 2, 2009

Hi guys,

I have a flat text database file with about 200 over records. How can i paginate them?

Appreciate if you can help me out, thanks.

Below is the script to get the records from the file

<?php
// Open log file
$logfile = "log.db";

if (file_exists($logfile)) {

$handle = fopen($logfile, "r");
$log = fread($handle, filesize($logfile));
fclose($handle);
} else {
die ("The log file doesn't exist!");
}

// Seperate each logline
$log = explode("\n", trim($log));
// After that it may be useful to get each part of each logline in a separate variable.
// This can be done by looping through each logline, and using explode again:

// Seperate each part in each logline
for ($i = 0; $i < count($log); $i++) {
$log[$i] = trim($log[$i]);
$log[$i] = explode('|', $log[$i]);
}

echo "<p>Total Entries : " . count($log) . "</p>";

// Show a table of the logfile
echo '<style type="text/css">
body {
background-color: #000;
color: #ffff80;
text-align: center;
font-family: "Trebuchet MS", "Times New Roman", Arial, Times, serif;
font-size: 13px
}

.wrapper {
width: 90%;
text-align: center;
margin: 0 auto;
}

a {
color: #33ccff;
text-decoration: underline;
}

a:hover {
text-decoration: none;
}

img {
border: 0;
}

.italic {
font-style:italic;
}

table {
width: 100%;
border-collapse: separate;
text-align: center;
margin: 0 auto;
font-size: 13px
}

td {
background-color: #0f0f4f;
padding: 3px;
border: 1px ridge #ccc
}

td.a {
width: 12%;
}

td.b {
width: 32%;
}

td.c {
width: 56%;
}

td.d {
background-color: #000;
}

</style>';
echo '<div class="wrapper"><table>';
foreach ($log as $logline) {
if ($logline['1'] == '') {
	echo '<tr>';
	echo '<td colspan="2"><b>' . $logline['2'] . '</b></td>';
	echo '<td class="c"><span class="italic">' . htmlspecialchars(urldecode($logline['5'])) . '</span></td>';
	echo '</tr>';
	echo '<tr>';
	echo '<td class="a"><b>IP Address</b><br /><span class="italic">' . $logline['0'] . '</span></td>';
	echo '<td class="b"><b>Hostname</b><br /><span class="italic">' . $logline['4'] . '</span></td>';
	echo '<td class="c"><b>Browser/OS</b><br /><span class="italic">' . $logline['3'] . '</span></td>';
	echo '</tr>';
	echo '<tr><td class="d" colspan="3"></td></tr>';
} else {
	echo '<tr>';
	echo '<td class="a"><a href="' . htmlspecialchars(urldecode($logline['1'])) . '"><b>Referer</b></a>';
	echo '<td><b>' . $logline['2'] . '</b></td>';
	echo '<td class="c"><span class="italic">' . htmlspecialchars(urldecode($logline['5'])) . '</span></td>';
	echo '</tr>';
	echo '<tr>';
	echo '<td class="a"><b>IP Address</b><br /><span class="italic">' . $logline['0'] . '</span></td>';
	echo '<td class="b"><b>Hostname</b><br /><span class="italic">' . $logline['4'] . '</span></td>';

	echo '</tr>';
	echo '<tr><td class="d" colspan="3"></td></tr>';
}
}
echo '</table></div>';

your do it something like this

<?php
$Page = 1;
$Entries = 30;

// Open log file
$logfile = "log.db";

if (file_exists($logfile))
{
#$handle = fopen($logfile, "r");
#$log = fread($handle, filesize($logfile));
#fclose($handle);
$fulllog = file($logfile);
} else {
die ("The log file doesn't exist!");
}

// Seperate each logline
#$log = explode("\n", trim($log));
// After that it may be useful to get each part of each logline in a separate variable.
// This can be done by looping through each logline, and using explode again:



$totalPages = ceil(count($log)/$Entries);
$end = $Entries*$Page;
$start = $end-$Entries;

// Seperate each part in each logline
$log = array();
for ($i = $start; $i < ($end); $i++)
{
$log[$i] = trim($fulllog[$i]);
$log[$i] = explode('|', $fulllog[$i]);
}

echo "<p>Total Entries : " . count($fulllog) . "</p>";

// Show a table of the logfile
//rest of your code

hi,

thanks for the reply.

it is displaying according to the $Entries.

Where can i get the link to the following page?

thanks.

MadTechie · April 2, 2009

if your using $_GET then just do a help like for "?Page=".($Page-1) and "?Page=".($Page+1) for previous and next

if you want a full page number list then just create loop from 1 to $totalPages with a simple echo "<a href='?page=".$n."' >$n</a>";

Hi,

i did something like this

for ($n = 1; $n <= $totalPages; $n++)
{
echo "<a href='?page=".$n."' >$n</a>";
}

i think it's wrong, because it's not displaying anything

Sorry, i'm not good at programming.

superkingkong · April 2, 2009

somehow, when i type the url?page=2 ..., it is still showing the same page.

MadTechie · April 2, 2009

did you update the code for the page ?

ie

$Page = (int)(!empty($_GET['page']))?$_GET['page']:1;

superkingkong · April 2, 2009

did you update the code for the page ?

ie
$Page = (int)(!empty($_GET['page']))?$_GET['page']:1;

no, I just used the same code on post#2 as you posted.

where do i need to update this code?

$Page = (int)(!empty($_GET['page']))?$_GET['page']:1;

?

pardon me for my lack of knowledge in php.

update:

i managed to get the link (page number) to display after i change one of the variable:

$totalPages = ceil(count($fulllog)/$Entries);

is it correct?

Replace the first $Page with the code above

pardon me for my lack of knowledge in php.

No worries your doing great,

$totalPages = ceil(count($fulllog)/$Entries);

Yep very correct.. i missed that (was untested),

superkingkong · April 2, 2009

thanks, the pagination is working, but there is a slight problem.

for eg, i have 55 records, so, it displays 6 pages (10 records/page)

on the 6th page (last page), after the last 5 records, the script continues to display the "title of the column" until it reaches "10" (the count of $Entries), without the value, since the record ends at 55, if u know what i mean.

example is here:

http://premium.sfdns.net/~superkin/logv.php?page=6

anyway to prevent that?

MadTechie · April 2, 2009

try this update

change

$totalPages = ceil(count($fulllog)/$Entries);
$end = $Entries*$Page;
$start = $end-$Entries;

to

$NumRecords = count($fulllog);
$totalPages = ceil($NumRecords/$Entries);
$end = $Entries*$Page;
$end = ($end > $NumRecords)?$NumRecords:$end;
$start = $end-$Entries;

superkingkong · April 2, 2009

try this update

change

$totalPages = ceil(count($fulllog)/$Entries);
$end = $Entries*$Page;
$start = $end-$Entries;

to

$NumRecords = count($fulllog);
$totalPages = ceil($NumRecords/$Entries);
$end = $Entries*$Page;
$end = ($end > $NumRecords)?$NumRecords:$end;
$start = $end-$Entries;

thanks.

it is still displaying 10 records on the last page. but right now, it is getting last five values from page 5th, and repeat it in page 6 as first five values, then follow by the real five values of page 6th as the last five values.

MadTechie · April 2, 2009

oops

change

$end = ($end > $NumRecords)?$NumRecords:$end;
$start = $end-$Entries;

to

$start = $end-$Entries;
$end = ($end > $NumRecords)?$NumRecords:$end;

aka just swap them

superkingkong · April 2, 2009

thanks a lot

it is displaying the right thing

about the page link,

instead of 1 2 3

do u know how can i display something like

1 2 3 ... Next > Last Page >>

or the < Previous and << first page?

and if i'm on page 3, page 3 will not be hyperlinked.

thank you very much

superkingkong · April 3, 2009

i can't edit my previous post.

i have managed to figured out the previous/next link.

but i'm stuck with the.. when i'm on page 3, page 3 will not be hyperlinked.

would you be able to help, please?

thank you.

redarrow · April 3, 2009

can you post your current code then we can not see it can we?
