cum fac sa mi afiseze fotografiile in tabel in ordinea cronologica cum au fost uplodate?

[Theboy22]

am urmatorul script:

<?php
$path = "upload";

if(isset($_POST['file']) && is_array($_POST['file']))
{
	foreach($_POST['file'] as $file)
	{	
		unlink($path . "/" . $file) or die("Failed to <strong class='highlight'>delete</strong> file");
	}
	header("location: " . $_SERVER['REQUEST_URI']); //redirect after deleting files so the user can refresh without that resending post info message
}
?>
<form name="form1" method="post">
<?php

$path = "upload";
$dir_handle = @opendir($path) or die("Unable to open folder");

while (false !== ($file = readdir($dir_handle))) 
{

if($file == "index.php")
continue;
if($file == ".")
continue;
if($file == "..")
continue;
echo "<input type='CHECKBOX' name='file[]' value='$file'>";

echo "<a href='upload/$file' target='_blank'>";
echo "<img src='upload/$file' alt='$file' style='height: 100px; width: 100px;'/></a>&nbsp;&nbsp;";

	


}
closedir($dir_handle);

?>
<br>
<input type="submit" name="Delete" value="Delete">
</form>

 

scriptul imi afiseaza fotografiile din folderul UPLOAD, dar as vrea sa le afiseze in ordine cronologica cum au fost upldate .

Mentionez fotograriile cand sunt uplodate in folderul UPLOAD au numele la data si ora de upload

Exemplu: 2022-03-30-14-33-33_62444e1d7cf18.jpg.

 

Imi cer scuze ca primul meu topic a inceput cu o cerere de ajutor.

Va multumesc anticipat

Parcurgi lista de fisiere (acel while al tau), extragi data din fiecare nume (explode dupa _), o convertesti in timestamp (strtotime) si formezi un array cu fisierele.

Ex.: $FILES_LIST[$file_timestamp] = $file;

Apoi sortezi $FILES_LIST, apoi parcurgi array-ul si-l afisezi. In loc de $file, cand formezi array-ul de fisiere, poti sa-l faci un pic mai "complex", adica de forma:

<?php
$FILES_LIST[$file_timestamp] = array(
  "name"=>$file_name, // aici trebuie sa extragi numele din path banuiesc
  "path"=>$file,
  "size"=>$file_size, // aici iei filesize-ul dupa $file
  // etc
);
?>

Ai putea inlocui 

$dir_handle = @opendir($path) or die("Unable to open folder");
while (false !== ($file = readdir($dir_handle))) 
{
if($file == "index.php")
continue;
if($file == ".")
continue;
if($file == "..")
continue;
echo "<input type='CHECKBOX' name='file[]' value='$file'>";
echo "<a href='upload/$file' target='_blank'>";
echo "<img src='upload/$file' alt='$file' style='height: 100px; width: 100px;'/></a>&nbsp;&nbsp;";
}
closedir($dir_handle);

Cu

function sortByTime($a, $b) {
    $datePuzzleA = explode("-", explode("_", $a)[0]);
    $dateA = strtotime(implode("-", array_slice($datePuzzleA, 0, 3))." ".implode(":", array_slice($datePuzzleA, 3, 3)));
    $datePuzzleB = explode("-", explode("_", $b)[0]);
    $dateB = strtotime(implode("-", array_slice($datePuzzleB, 0, 3))." ".implode(":", array_slice($datePuzzleB, 3, 3)));
    if ($a === $b) {
        return 0;
    }
    return $b > $a ? -1 : 1;
}

$files = array_diff(scandir($path), array('.', '..', 'index.php'));
usort($files, "sortByTime");
foreach($files as $file) {
    echo "<input type='CHECKBOX' name='file[]' value='$file'>";
    echo "<a href='upload/$file' target='_blank'>";
    echo "<img src='upload/$file' alt='$file' style='height: 100px; width: 100px;'/></a>&nbsp;&nbsp;";
}

Desi nu cred ca e cea mai eleganta solutie.
