Show 5 Results from foreach loop in html

Question

Hi I want to do some pagination with my array with my foreach loop so I did this:

$page = 0;
$i = 0;
foreach($time as $indTime){
    if($i % 5 == 0){
        $page++;
    }
    $i++;
}

So basically the first 5 result page = 1 the next 5 page=2 the next 5 page = 3 and so on. Now Im using twitter bootstrap and I want to use the pagination component which is basically links with << 1 2 3 4 5 >> to click on your page. What I need is when you click on 1, it shows every result from the foreach loop where $page = 1 when I click 2, $page = 2 etc. Anyone know how I could do this?

Answer 1

Route for the resource

You have to create routes for the pagination like: example.com/times/2 where 2 will be the page number, so you can use them in your links <a href="example.com/times/2">. Then get the number from the URL. Alternatively you can just pass the number as a GET or POST parameter.

Validate the number

You cannot trust user input, so check if the given number is valid.

Print the page

Finally just compare the page with the given/selected page number and print the items.

$time = Array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12);

$page_selected = 2;
$page = 1;
$i = 1;
foreach ($time as $indTime) {
    if ($page == $page_selected) {
      echo $indTime;
      echo ' ';
    }
    if ($i % 5 == 0) {
        $page++;
    }
    $i++;
}

This will print the items of the second page: 6 7 8 9 10.
