Opencart sayfasındaki bir butona tıklayarak dosyaları indirmek için ajax metodunu kullanabilirsiniz. Bunun için controller ve view dosyalarına ekleyeceğiniz kodlar aşağıdadır.
Controller:
public function downloadAllFiles() {
$json = array();
$zip_files = array(
"file-1.jpg",
"file-2.jpg",
"file-3.jpg",
);
if ( count($zip_files) > 0 ) {
$zipname = "indir.zip";
$zip = new ZipArchive;
$zip->open($_SERVER['DOCUMENT_ROOT']."/store/image/download/".$zipname, ZipArchive::CREATE);
foreach ($zip_files as $file) {
$zip->addFile($_SERVER['DOCUMENT_ROOT']."/store/image/download/".$file, $file);
}
$zip->close();
//success and send zip file path
$json['success'] = 'https://example.com/store/image/download/'.$zipname;
$this->response->addHeader('Content-Type: application/json');
$this->response->setOutput(json_encode($json));
}
else {
$json['error'] = "İndirilecek dosya bulunamadı! Lütfen kontrol ediniz.";
$this->response->addHeader('Content-Type: application/json');
$this->response->setOutput(json_encode($json));
}
}
View:
<!-- Add Download Button -->
<button id="btn-download-zip" data-loading-text="<?php echo $text_downloading; ?>" class="btn btn-info"><?php echo $text_download; ?> <i class="fa fa-download"></i></button>
<!-- Add Ajax Script -->
<script type="text/javascript">
$(document).delegate('#btn-download-zip', 'click', function() {
$.ajax({
url: 'index.php?route=sale/order/downloadallfiles',
type: 'post',
dataType: 'json',
beforeSend: function() {
$('#btn-download-zip').button('loading');
},
complete: function() {
$('#btn-download-zip').button('reset');
},
success: function(json) {
$('.alert').remove();
if (json['error']) {
$('#content > .container-fluid').prepend('<div class="alert alert-danger"><i class="fa fa-exclamation-circle"></i> ' + json['error'] + '</div>');
}
else {
//download zip file
window.location.href = json['success'];
}
},
error: function(xhr, ajaxOptions, thrownError) {
alert(thrownError + "\r\n" + xhr.statusText + "\r\n" + xhr.responseText);
}
});
});
</script>
