search and pagination not work - php

hello I try to combine the two scripts from the book PHP 6 and MySQL 5 for Dynamic Web Sites. I did search and pagination, but when I go to the next page - did not work.
I posted two screenshots below.
if someone could show me how I make a mistake I will be grateful.

you are facing issues because in your second url, the query parameter is missing, you should have also have the query=car parameter in get as the data that is been searched is searched with that parameter according to the script...
Change code from around line 184-204 to the following
// If it's not the first page, make a Previous button:
if ($current_page != 1) {
echo 'Previous ';
}
// Make all the numbered pages:
for ($i = 1; $i <= $pages; $i++) {
if ($i != $current_page) {
$distance = $current_page - $i;
if (abs($distance) < 5){
echo '' . $i . ' ';
}
} else {
echo $i . ' ';
}
} // End of FOR loop
// If it's not the last page, make a Next button:
if ($current_page != $pages) {
echo 'Next';
}

hello kind sirs can you help me with this code. What i try to do is when i type something in the search box, ex. pending it will show the 5 pending reservation per page(5 rows of pending reservation). but when i try it, it shows all the pending reservation which is more than 10.
here is the image
i try something like this.. but it shows nothing
$query = "SELECT * FROM reservations WHERE CONCAT(firstname, lastname, reservationstatus)LIKE '%".$valueToSearch."%' LIMIT " . $this_page_first_result . ',' . $results_per_page";
Here is the whole code

... when i try it, it shows all the pending reservation which is more than 10.
That's because when you hit 2nd, 3rd, ... pages(after navigating from the 1st page), the $_POST array would be empty i.e. $_POST['search'] won't be set, and that's why else{...} part of the code will get executed every time you navigate to 2nd, 3rd, ... pages. Since you're not sending any sensitive data with the form, use GET instead of POST in the method attribute of the form, like this:
<form action="..." method="get">
and get the user inputted data like this:
if (isset($_GET['search'])) {
$valueToSearch = $_GET['valueToSearch'];
...
Subsequently, you need to attach that search query in each of your pagination links, so that the search query would be available when you hop from page to page.
// your code
<?php
for($page=1;$page<=$number_of_pages;$page++)
{
echo "<a id='pagingLink' href='adminControl.php?page=" . $page . "&valueToSearch=". urlencode($_GET['valueToSearch']) ."&search'>" . $page . "</a>";
}
?>
// your code

Solution for pagination and $_post meaning

Hello i just finish my pagination and face a problem with my filter system i use from to filter and $_POST to extract data but the thing is when i go to second page the post meaning get to nothing and i am missing some data then in my case i got more then i filter it , i mean if i filter by location (london) i get 32 of 36 but when i go to second page i will get all 36 because $_post loses his meaning hare is my code and live page : My website

i need a possible solution for that , to catch post data and keep there until u change hare with a post method again or some other solution because now $_POST will be equal to null if u pass the second page on pagination

For this case you can instead change from $_POST to $_GET as this will be easier so solve your problem as well as any problems you might encounter in future. I think the majority of websites with pagination use variables in URL because it's much easier to track. Moreover, you're not sending any private data, so I don't see a reason why not switch to other method. You will have an option to use something like $_POST['page'] and accordingly to that you can retrieve other rows.

Just for encase I gave full code. The problem is, that PAGINATION on it's own working fine... And ORDER function working fine separately as well. BUT TOGETHER they do not want to work. As result I have working pagination and if try to use sort it's just become empty page.
What I need..is somehow make sorting method working with pagination together, but i'm stuck how to do it.
I have this url when I'm using pagination:
http://example.net/view.php?pn=3
And this one when I'm using order:
http://example.net/view.php?order=NEW&vType=Film&vGenre=AnyGenre1&vGenre2=AnyGenre2&vGenre3=AnyGenre3&vYear=AnyYear&vCity=AnyCity
AND I need that URL will be like this:
http://example.net/view.php?pn=3&order=NEW&vType=Film&vGenre=AnyGenre1&vGenre2=AnyGenre2&vGenre3=AnyGenre3&vYear=AnyYear&vCity=AnyCity
That if you sort the page... it will remember how user was sort the list and open pages (pn=1, pn=2) will change.
May be some how save sort result and then use it in pagination..need to save it maybe when submit button pressed? But how can I save result from user???

PHP - MySQL query with Pagination

How would I go about making a pagination script for this MySQL & PHP query.
if (isset($_GET['c'])) {
$c = $_GET['c'];
}
$query = mysql_query("SELECT * FROM Categories WHERE category = '$c' ");
WHILE($datarows = mysql_fetch_array($query)):
$id = $datarows['id'];
$category = $datarows['category'];
$code = $datarows['code'];
endwhile;
$query2 = mysql_query("SELECT * FROM Games WHERE category = '$code' ");
WHILE($datarows_cat = mysql_fetch_array($query2)):
$title = $datarows_cat['title'];
$description = $datarows_cat['description'];
$imgurl = $datarows_cat['image_name'];
$category = $datarows_cat['category'];
$views = $datarows_cat['view_count'];
$pagename = $datarows_cat['pagename'];
$featured = $datarows_cat['featured'];
if ($featured =="1") {$f = "<img src='http://my-site.com/images/star.png' width='13px' title='Featured Game' /> Featured"; } else {$f = "";}
if(is_int($views/2)) {
$views = $views / 2;
} else { $views = $views / 2 + .5; }
if (strlen($description) > 95) {
$desc= substr($description,0,95);
$desmod = "$desc...<br/>- Read More";
}
else {$desmod = "$description";}
echo "$f - $title - $desmod<br/>";
endwhile;
And when I visit http://my-site.com/categories/Action for instance, The code looks up that category in my category table, then once it gets the unique code for that category, It runs another query to find all games in another table with that category code. Currently, however, I have 200+ games loading for a single category which causes a great amount of loading time.
Thanks for your help!

First of all find out how many games are there for a specific category
change the line
$query2 = mysql_query("SELECT * FROM Games WHERE category = '$code' ");
to
$sql="SELECT * FROM Games WHERE category = '$code' ";
$query_count=mysql_query($sql);
Add following after it
$per_page =30;//define how many games for a page
$count = mysql_num_rows($query_count);
$pages = ceil($count/$per_page);
if($_GET['page']==""){
$page="1";
}else{
$page=$_GET['page'];
}
$start = ($page - 1) * $per_page;
$sql = $sql." LIMIT $start,$per_page";
$query2=mysql_query($sql);
Then display the numbers of pages where you want
<ul id="pagination">
<?php
//Show page links
for ($i = 1; $i <= $pages; $i++)
{?>
<li id="<?php echo $i;?>"><?php echo $i;?></li>
<?php
}
?>
</ul>
Use CSS for pagination this will do the trick

//database connation
<?php
$conn = new mysqli("localhost", "root", "","database_name");
?>

echo $nex;
";

Get all data from database.
$limit = 1;
if (isset($_GET["page"]))

}
else

Using PHP to search a MySQL database and return paged results

I've come across a problem but any help would be appreciated.
When I query the database using the results posted from a form, the pagination works initially i.e. for the first 10 records but when I click on the 2 hyperlink of the pagination for the second page of results it loses the $_POST variable and returns to the full data set.
What is the best way of keeping these variables available for the second (and further) pages?
The below is my complete php file.
<html>
<head>
<link rel="stylesheet" type="text/css"
href="design.css">
</head>
<body>
<?php
include("header.php");

<?php
include("../config.inc");
$find=$_GET['find'];
// get page no and set it to page variable, if no page is selected so asign first page bydefualt
if (isset($_GET["page"])){
$page = $_GET["page"];
}
else {
$page=1;
}
// count all record in this table then divide it on 10 in order to find the last page----- every page has 10 record display
$sql = "SELECT COUNT(*) FROM tt where TTT='$find' ";
$rs_result = mysql_query($sql);
$row = mysql_fetch_row($rs_result);
$total_records = $row[0];
$total_pages = ceil($total_records / 2);
// this line check that page no must be in integer format
$page = (int)$page;
if ($page > $total_pages) {
$page = $total_pages;
} // if
if ($page < 1) {
$page= 1;
} // if
$start_from = ($page-1) * 2;
$q=mysql_query("select * from tt where TTT='$find' order by ID limit $start_from,2");
$c=mysql_query("select count(*) from tt where TTT='$find'");
echo "<center>".mysql_result($c,0)."Filtered</center>";
echo "<center>";
echo "<table border='2' bgcolor=#CCCCCC>

while($row=mysql_fetch_array($q))
{
echo "<tr>";
echo "<td>".$row['TTT']."</td>";
echo "<td>".$row['Enroll_Date']."</td>";
echo "<td>".$row['Graduation_Date']."</td>";
echo "<td>".$row['ID']."</td>";
}
echo "</table>";
echo "<center>";
// paginatio start here
if ($page== 1) {
echo " << < ";
} else {
echo " <a href='{$_SERVER['PHP_SELF']}?page=1'><<</a> ";
$prevpage = $page-1;

} // if
?>
</div>
</center>
<?php

</html>

You have to pass the filtering criteria along with links to next pages.
echo " <a href='{$_SERVER['PHP_SELF']}?page=1&find=$find'><<</a> ";
and so on with every other link.
