Paging

[seularts]

i want to make this code:

 

<?php

if(file_exists('wr/events.php')){

$file = array_reverse( file( 'wr/events.php' ) );

foreach ( $file as $line ){

echo "$line\n";

}

}else{

echo "File doesn't exist";

}

?>

 

read from the events.php 10 items and then count the bext 10 items in a new page(same page) by pressing next!

the keyword you are looking for is "pagination"

It seems that pagination is for interacting with data bases.. and i`m reading from a simple file.. so can anyone give me some code to patch my own in order to get some pagination on the page?

Ok i managed to do this:

 

<?php

if(file_exists('wr/bands.php')){

$file = array_reverse( file( 'wr/bands.php' ) );

foreach ( $file as $line ){

 

}

}else{

echo '<p class="form"> No content can be displayed yet!</o>';

}

 

$page = (int)$_GET['page_number'];

$lines_per_page = 10;

 

$start = $page * $lines_per_page;

$end = $start + $lines_per_page;

 

for ($i = $start; $i < $end; $i++) echo $file[$i];

 

echo '<br /><a href="bands.php?page_number=' . ($page + 1) . '">Next page</a>';

 

?>

 

the problem is that the pages won't stop where the lines stop, so if i have 20 items and i show 10 pe page, there won't just be 2 pages.. i just keeps going pagining, can anyone give me a hint!?

If I'm hearing you right, your saying it won't stop saying Next Page when it reaches the last page. But that's because you haven't added anything to tell it to stop.

 

<?php
if ( $end < count($file) )
{
      echo "<a href=\"bands.php?page_number=" . ($page + 1) . "\">Next page</a>";
}
?>

pagination is the act of breaking down a list into separate pages.  Yes, it is most commonly used with databases, but it doesn't matter where the data comes from.  Glad you got it all sorted out.

One last thing.. how can i make the prevoius link work proprealy?

 

<?php

if(file_exists('wr/bands.php')){

$file = array_reverse( file( 'wr/bands.php' ) );

foreach ( $file as $line ){

 

}

}else{

echo '<p class="form"> No content can be displayed yet!</o>';

}

 

$page = (int)$_GET['page_number'];

$lines_per_page = 10;

 

$start = $page * $lines_per_page;

$end = $start + $lines_per_page;

 

for ($i = $start; $i < $end; $i++) echo $file[$i];

 

 

 

if ( $end < count($file) )

{

      echo "<a href=\"bands.php?page_number=" . ($page + 1) . "\">Next page</a>";

}

 

if ( $end > count($file) && $start < count($file))

{

      echo "<a href=\"bands.php?page_number=" . ($page - 1) . "\">Previous page</a>";

}

 

?>

 

it just shows only on the last page of products, how can i make it go back from page x to page 1, ofcourse in page not beeing displayed this link?

change line

if ( $end > count($file) && $start < count($file))

to

if ( $page > 0)
