[SOLVED] Paging

[newbtophp]

Im having trouble with paging, when im on the first page, the Previous displays, when im on the last page it still says Next when its meant to be Last.

 

Any other way of structuring?

 

This is how its structured:

 

<?php

$rss = new lastRSS; 
$searchx = $_GET["search"];
$search = $_GET["search"];
$start = $_GET["page"];
$replace = " "; $with = "+";
$search = str_replace($replace, $with, $search);
$title = "+"; $title2 = " ";
$titlefinal = str_replace($title, $title2, $s);
$perpage =  "1";	
$next = $start + $perpage;
$past = $start - $perpage;

?>

 

This is how I'd call it:

 

<a href="search.php?search=<? echo $search ?>&page=<? echo $past ?>" class="style2">
		Previous</a> | 
<a href="search.php?search=<? echo $search ?>&page=<? echo $next ?>" class="style2">
			Next</a>

Figure out how many pages there are. If the current page number equals the last page number, then the "Next" link shouldn't be shown. The first page is 1, so if that is the current page number the "Previous" link shouldn't be shown.

Can you provide some code to do this?, I dont get how I can define if the page numbers are the same.

[Daniel0]

Of course I could, but I'll leave it to you as an exercise. It's quite simple logic. I'm sure you can work it out if you try, and you'll benefit more by doing it yourself than having people feed you the answers

Well i got a rough idea:

 

$past and $next are always numbers, so before the $past and $next are echo'd I could use regex to check the if the $past and $next numbers are the same, then do an str_replace to remove.

 

But im new at regex, so I'll do some studying.

 

[Daniel0]

No, it's much simpler. Suppose we have a variable $numPages and a variable $currentPage. To determine if we should show the "Next" link we'll do:

if ($currentPage < $numPages) {
// display next
}

 

Almost similarly with the "previous" link:

if ($currentPage > 1) { // because 1 is the first page
// show previous
}

[newbtophp]

So it would be like:

 

<?php

$rss = new lastRSS; 
$searchx = $_GET["search"];
$search = $_GET["search"];
$start = $_GET["page"];
$replace = " "; $with = "+";
$search = str_replace($replace, $with, $search);
$title = "+"; $title2 = " ";
$titlefinal = str_replace($title, $title2, $s);
$perpage =  "1";   
$next = $start + $perpage;
$past = $start - $perpage;

if ($currentPage < $numPages) {
echo "<a href=\"search.php?search=$search&page=$next\">Next</a>\n";

}

if ($currentPage > 1) { // because 1 is the first page
echo "<a href=\"search.php?search=$search&page=$previous\">Previous</a>\n";
}

?>

 

But what would the $currenPage variable equal too...

[Daniel0]

Read my post... I said "suppose we have [...]". I didn't say that it was defined in your specific scenario. The variable $currentPage would obviously be a variable holding an integer value corresponding to whatever page the user is currently at.

[newbtophp]

I see, I've tried this but it dont work:

 

<?php

$rss = new lastRSS; 
$searchx = $_GET["search"];
$search = $_GET["search"];
$start = $_GET["page"];
$replace = " "; $with = "+";
$search = str_replace($replace, $with, $search);
$title = "+"; $title2 = " ";
$titlefinal = str_replace($title, $title2, $s);
$perpage =  "1";   
$next = $start + $perpage;
$past = $start - $perpage;

if ($start < $perpage) {
echo "<a href=\"search.php?search=$search&page=$next\">Next</a>\n";

}

if ($start > 1) { // because 1 is the first page
echo "<a href=\"search.php?search=$search&page=$previous\">Previous</a>\n";
}

?>

Try learning from this =)

 

<?php

//if the page is not set, set it to 1
if(!$_GET['page'])
$_GET['page']=1;

//ser the variable start to the current page.
$start = $_GET['page'];

$perpage = 1;   
$next = $start + $perpage;
$past = $start - $perpage;

//If the current page is less than or equal to 1 ($perpage) 
if ($start <= $perpage) {
//Echo the current page, and add a "next" button.
echo "Page #$start <br/>";
echo "<a href=\"?page=$next\">Next</a>";
}
//If the current page is bigger than one
if ($start > 1) { // because 1 is the first page
//Echo the current page, and add a "next" and "previous" button.
echo "Page #$start <br/>";
echo "<a href=\"?page=$past\">Previous</a> |";
echo " <a href=\"?page=$next\">Next</a> ";
}

?>

@ AngelicS

 

Thanks, that works great, but it can't determine the Last. It carries on and on, even though the search results dont have that many pages (they just repeat the same page)

 

And a minor change:

 

replace: ?page=

 

with: search.php?search=$search&page=

[AngelicS]

You'll have to find a way to find out how many pages there are, and then do the following.

 

Create a variable that contains the maximum number of pages.

 

For example:

$max_pages=10 //In this case, but you might want to check by looking in a database or something.

 

Then change the following code:

if ($start > 1 && <= $max_pages) { // because 1 is the first page
//Echo the current page, and add a "next" and "previous" button.
echo "Page #$start <br/>";
echo "<a href=\"?page=$past\">Previous</a> |";
echo " <a href=\"?page=$next\">Next</a> ";
}

 

And add the following code:

if ($start <= $max_pages)
{
echo "<a href=\"?page=$past\">Previous</a>";
}

 

 

And about the search thing, you just have to add it =)

I've added the modifications, except havent figured out a way to make it complete. I can't get the paging to say Last when its last page.

Anyone, can help please

Did you even try to read my last post?

Because the code you need is there.

Yes, I did, it worked great, but I can't figure out how I'd identify how many pages their is, since the data is coming externally from yahoo, and not a database. Theirfore each search result has a different number of pages. If you could point me to the right direction I'd really apreciate it.

 

If you save the above code as search.php and then access it you'll see the how it looks.

This is the first sentence in the chapter on counting in my discrete mathematics book:

Techniques for counting are important in mathematics and in computer science, especially in the analysis of algorithms.

 

Now I'll guess what you're supposed to do in order to figure out how many pages there are.

Mind sharing how you'd do it, so I can learn from it and mind telling me whats the book called?

[Daniel0]

The book is called Discrete Mathematical Structures by Kolman, Busby and Ross, but that's beside the point. My point was that you figure out the number of pages by counting the number of items. You then just divide by the number of items you want per page and ceil that number.

Im trying to get 10 items per page. Im counting the items by $i++;.

 

So 10 divided by $i++ then ciel?

Thanks, but it goes to 100, some searches only need to 2 pages, not all have 100 pages, the ones that dont have 100 pages just loop continuously until they get to 100.

Your stuffed with a total

 

Thanks, but it goes to 100, some searches only need to 2 pages, not all have 100 pages, the ones that dont have 100 pages just loop continuously until they get to 100.

 

 

Yeah what i meant to say was - Your stuffed without a total .

 

You need to be getting $content_count = ????????; which is the total amount of items from somewhere

Danny mentioned to get the total, divide the number of items per page by the number of items in total

 

The following snippet, is for when the items/results get parsed:

 

          // Parse ITEMS
            preg_match_all("'<item(| .*?)>(.*?)</item>'si", $rss_content, $items);
            $rss_items = $items[2];
            $i = 0;
            $result['items'] = array(); // create array even if there are no items
            foreach($rss_items as $rss_item) {
                // If number of items is lower then limit: Parse one item
                if ($i < $this->items_limit || $this->items_limit == 0) {
                    foreach($this->itemtags as $itemtag) {
                        $temp = $this->my_preg_match("'<$itemtag.*?>(.*?)</$itemtag>'si", $rss_item);
                        if ($temp != '') $result['items'][$i][$itemtag] = $temp; // Set only if not empty
                    }
                    // Strip HTML tags and other bullshit from DESCRIPTION
                    if ($this->stripHTML && $result['items'][$i]['description'])
                        $result['items'][$i]['description'] = strip_tags($this->unhtmlentities(strip_tags($result['items'][$i]['description'])));
                    // Strip HTML tags and other bullshit from TITLE
                    if ($this->stripHTML && $result['items'][$i]['title'])
                        $result['items'][$i]['title'] = strip_tags($this->unhtmlentities(strip_tags($result['items'][$i]['title'])));
                    // If date_format is specified and pubDate is valid
                    if ($this->date_format != '' && ($timestamp = strtotime($result['items'][$i]['pubDate'])) !==-1) {
                        // convert pubDate to specified date format
                        $result['items'][$i]['pubDate'] = date($this->date_format, $timestamp);
                    }
                    // Item counter
                    $i++;
                }
            }

            $result['items_count'] = $i;
            return $result;
        }

 

So the trouble is trying to get the total, because their is no default total or a way of getting a number, is their some way i can define the total from the above snippet? so i can get the pagination to work.

[Daniel0]

You know, there is this nifty function called count that counts the number of elements in an array (or an object implementing the Countable interface). Now, who would have thought that?

 

Of course there is no default total.
