Hi all i am trying to attempt to create my own pagination system i am trying to figuring out how to do a pagination system for my gallery
this is my code
Doesnt seem to work how i want it to do i want it to have a pagination system of what is in the cid so cid is the category number so doesnt matter how many images there are in the gallery system i want it so its 3 pictures per pagePHP Code:<form method="post" action="">
<input name="cid" type="hidden" value="<? echo $cid?>">
</form>
<?php
$cid=($_GET['cid']);
$imagethumbnail=$_POST['imagethumbnail'];
if($_GET['cid'])
{
$cid=($_GET['cid']);
$imagethumbnail=$_POST['imagethumbnail'];
$cid=$_GET['cid'];
//$pid=$_GET['pid'];
//echo $pid;
include("dbconnect.php");
$gQuery="SELECT * FROM gallery WHERE cid='$cid'";
//excute the query
//echo $gQuery;

How-To Paginate w/PHP/MySQL
First, I have to point out that your technique of querying the database with a GET variable is very dangerous. You can research "sql injections" to find out why. I recommend you change your code:
Change
$cid=$_GET['cid'];
$gQuery="SELECT * FROM gallery WHERE cid='$cid'";
To
$cid=(int)($_GET['cid']);
$gQuery="SELECT * FROM gallery WHERE cid='$cid'";
This makes sure that "cid" is only a number or will be set to 0 (which is safe).
Now, how to paginate. In general, you have several things to do:
1. Figure out how many pages there are
2. Figure out what records you need to retrieve
3. Build your First, Previous, Next and Last links
4. Display your data
To figure out how many pages there are you can either run your complete query and then get the record count with mysql_num_rows($result) or you can write a separate query to retrieve the record count in a more efficient way "SELECT count(*) AS count FROM gallery...".
Either way, you only have to do this once because you can then store the number of records with each navigation link. This means that if any additional records are added, they won't get picked up so you have to decide to either run the query to find the record count with every page load or pass it along with the nav links.
When your page is loaded you need to check to see if there is a $_GET["page"] variable set. This is the variable you pass to determine what page you are on. If it is not set then you are obviously on page 1.
When you build your navigation links include the page number variable and the total number of records variable in the links. You can build the variables to use with the example below:
if ($totalRecords < 1){
$totalRecords = 0;
$startRecord = 0;
$endRecord = 0;
$firstPage = 0;
$lastPage = 0;
$pageNum = 0;
}
else{
$pageNum = 1;
if (isset($_REQUEST["page"]))
$pageNum = $_REQUEST["page"];
$startLimit = ($pageNum - 1) * $maxRows; // 0 offset to the record to start from
$endLimit = $startLimit + $maxRows;
$startRecord = $startLimit + 1;
$firstPage = 1;
$lastPage = (int)ceil($totalRecords / $maxRows);
$prevPage = $pageNum - 1;
if ($prevPage < 1)
$prevPage = 1;
$nextPage = $pageNum + 1;
if ($nextPage > $lastPage)
$nextPage = $lastPage;
$endRecord = $startRecord + $maxRows - 1;
if ($endRecord > $totalRecords)
$endRecord = $totalRecords;
If you are on page 3 ($maxitems = 3 items per page):
previous page link = gallery.php?cid=1&page=$prevPage&reccount=$totalRecords;
next page link = gallery.php?cid=1&page=$nextPage&reccount=$totalRecords;
first page link = gallery.php?cid=1&page=$firstPage&reccount=$totalRecords;
last page link = gallery.php?cid=1&page=$lastPage&reccount=$totalRecords;
Now, when you display your data, only query the database for the actual records you need:
"SELECT * FROM gallery WHERE cid='$cid' LIMIT $startlimit, $maxrows".
Loop through all records returned.
Things to note:
You'll need to put logic around your navigation links because you don't want to display them if they are irrelavent (i.e. don't display the "first page" link if you are on the first page).

here is a function that i made for myself:
And i used like this:PHP Code:function PaginateData($start,$perPage,$total,$page){
if($total >= 1){
echo "<b>";
//for previous
$previous = $start - $perPage;
if($start > 0 and $start < ($total - $perPage))
echo " <a href=\"$page&start=$previous\" class=\"A2\" title=\"Previous\">« Previous</a> ";
else if($start > 0 and $start >= ($total - $perPage))
echo " <a href=\"$page&start=$previous\" class=\"A2\" title=\"Previous\">« Previous</a> ";
//complete previous
echo "Page : | ";
$l = 1;
for($i = 0; $i < $total; $i = $i + $perPage){
if($i != $start)
$a[$l] = "<a class=\"A2\" href=\"$page&start=$i\">$l</a> ";
else
$a[$l] = "$l ";
$l++;
}
foreach($a as $p=>$pp)
echo $pp;
//for next
echo " | ";
$next = $start + $perPage;
if(($start == 0) and $total > $perPage)
echo " <a class=\"A2\" href=\"$page&start=$next\" title=\"Next\">Next »</a>";
else if($start > 0 and $start < ($total - $perPage))
echo " <a class=\"A2\" href=\"$page&start=$next\" title=\"Next\">Next »</a>";
//complete next
}
echo "</b>";
}
And finnaly i called the function like this:PHP Code://paging
$perPage = 40;
$total = 0;
if(isset($_REQUEST['start'])){$start = $_REQUEST['start'];}
else{$start = 0;}
This may help you.PHP Code:$url = "show_visitinfo.php?ProjectID=$prjid&fdate=$FDate&tdate=$TDate";
PaginateData_($start,$perPage,$total,$url)
I have not studied your code.

Try this.
You may have to change the code to suit your database, etc...
Near to the top of the page place this there:
Place this code at the very end of your mysql_query for your results:PHP Code:// category id
$cid = (int)($_GET['cid']);
// category id form the pagination back
$backpage = (int)($_GET['back']);
// get page number
if(!isset($_GET['page']))
{
$page = 1;
}
else
{
$page = $_GET['page'];
}
// Define the number of results per page
$max_results = 20;
// Figure out the limit for the query based
// on the current page number.
$from = (($page * $max_results) - $max_results);
Place this after your list of results:PHP Code:ORDER BY whatever DESC LIMIT $from, $max_results
// so it would look something like this
$result = mysql_query("SELECT blah, blah FROM my_table WHERE blah=blah ORDER BY whatever DESC LIMIT $from, $max_results");
I hope this helps morePHP Code:if($max_results)
{
$result_final .= "<div>
<p align='left'>";
// Figure out the total number of results in DB:
$total_results = mysql_result(mysql_query("SELECT COUNT(*) as Num FROM my_table WHERE blah=".addslashes($cid)." "),0);
// Figure out the total number of pages. Always round up using ceil()
$total_pages = ceil($total_results / $max_results);
if ($total_pages >= 1)
{ // build links if more than one page
// Build Page Number Hyperlinks
$result_final .= "page: ".$page.' of '.$total_pages.";
// Build first page link
if(($page) > $max_results)
{
// check if the page sent
// does it equal the amount of total_pages?
if($page == $total_pages)
{
$start = ($page - $max_resultsl);
$end = ($page * 1);
$result_final .= "<a href=\"".$_SERVER['PHP_SELF']."?cid=$cid&back=$backpage&page=1\" title='First Page'>« first</a>";
} else {
$start = ($page - $max_resultsl);
$end = ($page + 1);
$result_final .= "<a href=\"".$_SERVER['PHP_SELF']."?cid=$cid&back=$backpage&page=1\" title='First Page'>« first</a>";
}
} else {
if($total_pages < $max_results){
$start = 1;
$end = $total_pages;
} else {
$start = 1;
$end = $max_results;
}
}
// Build Previous Link
if($page > 1){
$prev = ($page - 1);
$result_final .= "<a href=\"".$_SERVER['PHP_SELF']."?cid=$cid&back=$backpage&page=$prev\" title='Previous Page'>‹</a>";
}
// start from / end to number of pages
for($i = $start; $i <= $end; $i++)
{
// Build the number of pages as numbers
if(($page) == $i){
$result_final .= "$i";
} else {
$result_final .= "<a href=\"".$_SERVER['PHP_SELF']."?cid=$cid&back=$backpage&page=$i\" title='Page ".$i."'>$i</a>";
}
}
// Build Next Link
if($page < $total_pages)
{
$next = ($page + 1);
$result_final .= "<a href=\"".$_SERVER['PHP_SELF']."?cid=$cid&back=$backpage&page=$next\" title='Next Page'>›</a>";
}
// Build last page link
if($total_pages > $max_results)
{
$result_final .= "<a href=\"".$_SERVER['PHP_SELF']."?cid=$cid&back=$backpage&page=$total_pages\" title='Last Page'>last »</a>";
}
$result_final .= "</p>
</div>
<br />";
}
else
{
$result_final .= "\n";
}

Here is what i have you may need to change it but this is what i got and feel free to change it the way you want it to work aswell.
Here is what i have
PHP Code:$cid=($_GET['cid']);
if($_GET['cid'])
{
$cQuery="SELECT * FROM gallery WHERE cid='$cid'";
$result=mysqli_query($con,$cQuery);
if(!$result)
{
echo "Error:".mysqli_error($con);
}
else
{
$count=$result->num_rows;
if($count>0)
{
while($data=$result->fetch_assoc())
{
$cid=$data['cid'];
$alt=$data['alt'];
$description=$data['description'];
$imagethumbnail=$data['imagethumbnail'];
}
}
else
{
echo "<br/>There is no Gallery Informartion Found<br/>";
}
}
}?><form method="post" action="">
<input type="hidden" name="cid" value="<?php $cid ?>"></form>
<?php
$num = $_GET['num'];//Get the numeration of the page
if(empty($num)){//if the numeration is empty
$num = 1;//the numeration is 1
};
$limit = 3;//Sets the limit of results to display in each page, change if you want.
/*
The query will start selecting the numeration, for example 2, less 1, that would be 1
* the limits of results to show per page, 2 in this case so it would be 1*2 = 2, it will
start from 2 ;) if the limit would be 5 and the numeration would be 3 if would be (3-1)*5 = 10
*/
$start = ($num-1)*$limit;
$start = round($start,0);//rounds the result
/*
This query will select the contrene FROM the start and with a limit of 2, in this case,
because the variable $limit is 2
You can add a WHERE something= '$something' for example, or delete the ORDER by `id`, or change it,
etc
*/
$query = "SELECT * FROM gallery where cid='$cid' ORDER by `id` LIMIT $start, $limit";
$result = mysqli_query($con,$query);//now it makes the query and names it as result
/*
While will repeat this query and mysql_fect_array allow me array the content
*/
echo "<table>";
while ($data = mysqli_fetch_array($result)){
echo "<tr><td><a href=\"showart.php?id=".$data['id']."\"><img src=gallery/".$data['imagethumbnail']." width=\"100px\" height=\"100px\" alt=".$data['alt']."></a></td><td>".$data['description']."</td></tr><br/>";//Echoes the content
};
echo "</table>";
$totalpages = mysqli_num_rows(mysqli_query($con,"SELECT * from gallery where cid='$cid'"));//Get the total number of results
/*
Total resutls/ the limit, in this example is 2, so if there are 10 total result and the limit is 2
there will be 5 pages.
*/
$totalpages = $totalpages / $limit;
$totalpages = round($totalpages,0);
$c = 0;//The variable c is 0
echo "<br>";//make a <br> to separate the results from the [1][2]...
while($c<$totalpages){//while c is < than the total pages
$page = $c + 1;//sets the variable $page as 0 + 1 = 1
if($_GET['num']==$page){//Gets the number of the page and if its the same that the page
echo "[$page] ";//its only echoes the page, not the url to this page
}else{//else
echo "<a href=?cid=".$cid."&num=$page>[$page] </a>";//it echoes the url to the page
}
$c = $c+1;
}
echo "<br>".$totalpages." Pages in total.";//echoes the total pages
