PHP Pagination (Adjacent)

[Rita_Ruah]

Hello, I have manually created a simple pagination function, but unfortunately, I am having trouble when it comes to limit the number of pages shown... 

At the present, If there are 10 pages, I show all the pages, but my goal was to only show 5 pages... 

Example:

If I am on page 1 I only see:
[1] 2 3 4 5

 

If I am on two:

 

[2] 3 4 5 6

 

If I am on three: 

 

[3] 4 5 6 7

 

What should I do? this is my current cycle:

 

if($number_pages > $num_pages_list /*5 in this case*/)

{

 

for($i=1; $i <= $number_pages; $i++)

{

if($i == $_GET['page'])

{

echo '<a href="'.$page.'?page='.$i.'&i='.($results_page*$i-$results_page).'"><b>'.$i.'</b></a>';

}else{

echo '<a href="'.$page.'?page='.$i.'&i='.($results_page*$i-$results_page).'">'.$i.'</a>';

}

}

 

}

 

In this example I still show every page...

for($i=1; $i <= $number_pages; $i++)

Fix that line. If you know what it does, it should be fairly easy to change it to what you've just said you want it to do.

Hi there, I know what it does, for i equals 1, while i is lower or equals number_pages, etc etc...

 

But I am not sure what to do here, can you give me a hint? Please, I am stuck here for hours... 

 

Thanks!

[Rita_Ruah]

for($i = $_GET['page']; $i <= $number_pages; $i++)

{

//Maybe this?

//Please help or explain the logic of what to do, the rest i will be capable to do.

//Sorry

}

Well, your complaint is that it's printing all the numbers up to $number_pages. You want it to print up to $num_pages_list.

 

You also are starting at 1 right now. You say you want to start at the current page.

 

There are two things to change.

Oh sorry, my bad, ok, I'm going to try to explain again:

 

Currently, my pagination works fine (next - previous - first page - last page), but the problem is that I need to only show 5 numbers (five pages at once, and currently I am showing every page).

 

What I want is showing every page buuuuut make sure that there are only 5 pages at once, thus the example (imagine that there is a total of 7 pages in the pagination:

 

If I am at page 1 I will see:

 

[1] 2 3 4 5

 

If I am at page 2 I will see:

 

[2] 3 4 5 6

 

If I am at page 3:

 

[3] 4 5 6 7

 

If I am at page 4:

 

3 [4] 5 6 7

 

Did you understand? (Sorry I am italian)

[Jessica]

Yes, I understand. I told you what your code is doing now. Change those parts to do what you want.

[Rita_Ruah]

Yes, I understand. I told you what your code is doing now. Change those parts to do what you want.

 

The first part I think that it's assigning the current page for $i, right?

Next I have no idea... Please help... I feel dizzy, pagiantion was fine and was my favorite project until this problem  

I only ask because I am desperate...

[Jessica]

You can't be that desperate, you didn't even try to change it.

[Rita_Ruah]

You can't be that desperate, you didn't even try to change it.

 

But I am on my tablet, is there any php editor/run for tablet (android)?

 

Only tomorrow I will be able to try to fix it... please Jessica, if you don't want to give the answer, atleast try to explain to me what to do... I am thinking about:

 

for($i = $_GET['page']; $i <= $num_pages_list+$_GET['page'];i++)

{

if($i <= $num_pages)

{

echo $i;

}

}

 

EDIT: This won't work because the pages aren't limited to 5 right? 

Damn...

This looks good thanks

Whenever I finish the function to paginate (it's a pagination without database), I will tell if it worked! Thank you Jessica!
