Now i have every thing working, the pagination is a bit fine, only when i click next to go to page 2 or 3, nothing is being shown on the page, the browser shows that i am on the page2 but no data is beeing shown, now when i force the page to be 2 or 3 i see the rest of the data, what am i doing wrong?

I have been researching this for a while and still didn't figure this out, i was told that the &_POST is not being passed, but i don't know what is going on and how to fix that, i am a bit nw to php and i'm stitching together code as i go along, on other thing that i have to do is secure the data from injection i may need help with that aswell, can anyone help me with this please thanks!

<?php    

if(isset($_POST['submit'])){
if(isset($_GET['go'])){
if(preg_match("/[A-Z | a-z]+/", $_POST['name'])){
$name=$_POST['name'];

include "connect/connect.php";

//-query the database table
$sql=mysql_query("SELECT userId, Attribute, Name FROM government  WHERE Name LIKE '%" . $name . "%' OR Attribute LIKE '%" . $name . "%' ORDER BY userid ASC");

///////////////-PAGINATION LOGIC./////////////
$nr=mysql_num_rows($sql); // Get total of Num rows from the database query
if (isset($_GET['pn'])) { // Get pn from URL vars if it is present
$pn = preg_replace('#[^0-9]#i', '', $_GET['pn']); // filter everything but numbers for security(new)
} else { // If the pn URL variable is not present force it to be value of page number 1
$pn = 1;
}

//This is where we set how many database items to show on each page 
$itemsPerPage = 7; 

// Get the value of the last page in the pagination result set
$lastPage = ceil($nr / $itemsPerPage);

// Be sure URL variable $pn(page number) is no lower than page 1 and no higher than $lastpage
if ($pn < 1) { // If it is less than 1
$pn = 1; // force it to be 1
} else if ($pn > $lastPage) { // if it is greater than $lastpage
$pn = $lastPage; // force it to be $lastpage's value
}

Whne it comes to pagintion - there are about 2 new threads per week on it. Have you searched the forum? I'm a little confused - how are you passing info - form or link? If by link, no POST data will be sent. However forms can send via POST or GET.

I am not get the data to be passed, i am using form to pass the data eg:

<form method="post" action="search_govern.php?go" id="searchform">
  <input type="text" name="name">
  <input type="submit" name="submit" value="go">
</form>

this code is at the start of mp php block, every thing is working, i can search my data base the info comes up but when time to click page 2, i go to page 2, but no data comes up, this is very frustrating!

Shouldn't the action have a 'pn' parameter too?

<form method="post" action="search_govern.php?go=1&pn=<?php echo $pageno;?>" id="searchform">

Or something similar?

I would think so, but here's the thing the form is actually at the very top of the php blaock of codes, so putting

<form method="post" action="search_govern.php?go=1&pn=<?php echo $pageno;?>" id="searchform">

is causing an error Notice: Undefined variable: pageno in search_govern.php on line 73 Call Stack #TimeMemoryFunctionLocation 10.0012753432{main}( )..\search_govern.php:0 " id="searchform">

I'd advise placing all the php processing at the top of the page, then if there's any html - place it below. You need php/html separation.

Ok thanks i'll try it and get back to you, i appreciate your help!
