Question

I’m currently using the following snippet for an improvised pagination system. Unfortunately, I’ve run into a bit of a roadblock. The variable $result->info['pages'] is returned by a remote API and is the number of pages available. The variable $result->info['page'] is the currently visible page. The links appear as expected an in the right place, but they act as if the page is ALWAYS 1 (The ‘1’ link always shows as plaintext, everything else always shows as a link). However, if I echo the $result->info['page'], it shows the correct page number, and the information displayed is correct. Thoughts as to what I might be doing wrong?

<?php if ($result->info['pages'] > '1') {
    if ($result->info['page'] != '1') {
        echo '<a onClick="location.replace(\'?page=' . --$result->info['page'] . '\');">Prev</a> ';
    } else {
        echo 'Prev ';
    }
    for ($i = 1; $i <= $result->info['pages']; $i++) {
        if ($i == $result->info['page']) {
            echo $i . ' ';
        } else {
            echo '<a onClick="location.replace(\'?page=' . $i .'\');">' . $i . '</a> ';
        }
    }
    if ($result->info['page'] != $result->info['pages']) {
        echo '<a onClick="location.replace(\'?page=' . ++$result->info['page'] . '\');">Next</a>';
    } else {
        echo 'Next';
    }
} ?>

You don’t need to modify --$result->info['page'], just replace it with ($result->info['page'] - 1) and everything will go well

<?php

$result = new stdClass();
$result->info = array(
    'pages' => 2,
    'page' => 2
);

if ($result->info['pages'] > '1') {
    if ($result->info['page'] != '1') {
        echo '<a onClick="location.replace(\'?page=' . ($result->info['page'] - 1) . '\');">Prev</a> ';
    } else {
        echo 'Prev ';
    }
    for ($i = 1; $i <= $result->info['pages']; $i++) {
        if ($i == $result->info['page']) {
            echo $i . ' ';
        } else {
            echo '<a onClick="location.replace(\'?page=' . $i .'\');">' . $i . '</a> ';
        }
    }
    if ($result->info['page'] != $result->info['pages']) {
        echo '<a onClick="location.replace(\'?page=' . ($result->info['page'] + 1) . '\');">Next</a>';
    } else {
        echo 'Next';
    }
}
