Help with Descending sorting

angels · December 23, 2020

Hi! I am absolute noob in php, but need to create descending sorting by last modified/date. How I could achieve this? Many thanks for help!

echo '<table class="wp-list-table widefat fixed striped" style="max-height: 500px;overflow-y:scroll;">';

If the files data is coming from DB query, do the sort in the query, otherwise use a custom sort function.

uasort($files, function($a, $b) { return $b['time'] <=> $a['time]; } );

(For ascending sort, switch a and b in the return)

thanks for the answer, but as I am noob, I do not understand where to put this code.

Putting this right now anywhere - gives me critical error

angels · December 23, 2020

I will to pay for this, could not know where to ask for help. I am using edd s3 plugin for wordpress and every time I retrieve file from amazon it show me old files first, and I need to show me the latest files, in descending sorting. Please, help me to change this plugin!

Barand · December 23, 2020

You have a foreach () loop in your code which process the array $files

2 hours ago, angels said:

foreach ( $files as $key => $file ) {

You need to put that sort code before that loop

maxxd · December 23, 2020

Put it before the first line. If it's throwing errors, post them here.

Here is full code - and I need to sort by date here

You need to put that sort code before that loop

There is a syntax error in my code - there's a missing ' character

    uasort($files, function($a, $b) { return $b['time'] <=> $a['time']; } );
                                                                    ^
                                                                    Add

now have no error, but code did not work - nothing changes, the same last modified ascending sorting of files

Barand · December 25, 2020

The sort code worked for me

Array
(
    [0] => Array
        (
            [name] => DSCN0025.JPG
            [time] => 1399035071
        )

    [1] => Array
        (
            [name] => DSCN0055.JPG
            [time] => 1453121551
        )

    [2] => Array
        (
            [name] => DSCN0052.JPG
            [time] => 1575540845
        )

    [3] => Array
        (
            [name] => DSCN0043.JPG
            [time] => 1330013161
        )

    [4] => Array
        (
            [name] => DSCN0062.JPG
            [time] => 1527770426
        )

)
Original array of files

Sort the array

Code:

<?php
    $arr = glob('Pictures/Nikon Transfer 2/001/*.JPG');
    shuffle($arr);
    $files = [];
    foreach ($arr as $k => $f) {
        $files[$k]['name'] = basename($f);
        $files[$k]['time'] = filemtime($f) ;              
    }

    echo '<pre>', print_r($files, 1);  

    echo "Original array of files\n\n";

    foreach ($files as $f) {
        printf("%-15s %15s\n", $f['name'], date('Y-m-d', $f['time']));
    }

    echo "\n\nSort the array\n\n";

    uasort($files, function($a, $b) { return $b['time'] <=> $a['time']; });

    foreach ($files as $f) {
        printf("%-15s %15s\n", $f['name'], date('Y-m-d', $f['time']));
    }

    echo '</pre>';
?>
