  • 0

What I am hoping to do is display the first 5 items (Stage1 – Stage5) from the array when the page is loaded. To the side I will have two images one arrow pointing up and one arrow down. If the down arrow is clicked the array is incremented to display (Stage2 – Stage6). Another click on the down arrow the screen would display (Stage3 – Stage7). Then the up arrow does the same but the opposite direction.

With the code I have below I can manually add “1” to $var1 and $var2 or subtract 1 when needed, save and refresh the browser to get the effect I am looking for. I just can’t seem to figure out how to do the increments of $var1 and $var2 and then refresh the page, all automatically when the arrow images are clicked.

I am new so I could be completely off with what I have but hopefully it at least helps show what I want to do.

<?php

$stage_name=array
("Stage1","Stage2","Stage3","Stage4",
"Stage5","Stage6","Stage7","Stage8",
"Stage9","Stage10","Stage11","Stage12",
"Stage13","Stage14","Stage15","Stage16");

?>
<html>
<body>
<?php
$var1=0; $var2=5;
for($list=$var1; $list<$var2; $list++)
{
    foreach($stage_name as $stage_index => $stage_item)
    {
        if ($stage_index==$list)
            print("$stage_item<br />");
    }
}
?>
</body>
</html>

Thanks

    $stageNames = array("Stage1", "Stage2", "Stage3", "Stage4",
                    "Stage5", "Stage6", "Stage7", "Stage8",
                    "Stage9", "Stage10", "Stage11", "Stage12",
                    "Stage13", "Stage14", "Stage15", "Stage16");

$offset  = isset($_GET['offset']) ? $_GET['offset'] : 0;
$perPage = 5;

if ($offset > 0) {
    printf('<a href="here.php?offset=%d">Up</a>', $offset - 1);
}

foreach (array_slice($stageNames, $offset, $perPage) as $stageName) {
    echo $stageName . '<br>';
}

if ($offset + $perPage < count($stageNames)) {
    printf('<a href="here.php?offset=%d">Down</a>', $offset + 1);
}
