Push file to download after AJAX post

Recommended Posts

Hi folks,

 

On the website I am working on I do have a form which needs to be filled in (duh) and when the user clicks on download, the data is send with ajax and processed in the same file by using the ProcessWire API with $config->ajax;

The data which is provided by the user will be checked with data in my database. If the data is correct I want to push a file download. But this is not working at the moment. It seems like the content of the (.exe) file is pasted in the console instead of pushing the file. My code looks like this:

if ($config->ajax){  
    $serial = $input->post('serial');
    $DB = DB();
    $query = $DB->prepare("/*My query here*/");
    $query->bindParam("comparision", $serial, PDO::PARAM_STR);
    $query->execute();

    $reply = '';

    $SN_rows = $query->rowCount();
    if (!$SN_rows > 0) {
        $reply = 'error';
    } else {
        $reply = 'success';
    $installer = $page->attachments->eq(1);
    $filename = "Filename";
    $filepath = $installer->filename;

    $options = array(
        'forceDownload' => true,
        'exit' => true,
        'downloadFilename' => $filename
    );

    wireSendFile($filepath, $options);
    }

    echo $reply;
    exit();
}

What am I doing wrong here or is it a bug? Is there another way to do this with the processwire API?

 

Thanks in advance,

@Robin S, thanks for the links. I fixed or cheated it in a bit different way. In the success function of the AJAX Post, I check for the reply if it is success or not. If it is equal to success I redirect to the same page with a query behind the normal URL. In the file I check if the query is in the URL and if so I push the file as a download. The only thing insecure to this method is that if you know the query you can still get the file without a serialnumber. Anyway, it works for the time being, hopefully this helps someone else

      I have a page with a table. Each table row has a page-reference field and a checkbox.
      The Page sends emails to all users (page-refrence->email-field) and change the value of the checkbox in a row to 1.
      It works with this:
      <?php // event ID fron url query $eventID = $input->get('eventID','int'); // get event-page $event = $pages->get($eventID); // config $fromEmail = $event->event_mail_from; $fromName = $event->event_mail_from_name; $emailSubject = $event->event_subject; // email html body ob_start(); include('./_inc/emailbody.inc'); $emailBody = ob_get_clean(); // make event-page editable $event->of(false); // loop through table and send out emails foreach($event->event_clients_list as $event_table_row) { // get client page $clientPage = $event_table_row->client_name; // get client email $clientEmail = $clientPage->email; // if client isn't invited yet (checkbox not checked) if($event_table_row->client_invited == '') { // send email $m = new WireMail(); $m->to($clientEmail); $m->from($fromEmail, $fromName); $m->subject($emailSubject); $m->bodyHTML($emailBody); $m->send(); // mark client as invited $event_table_row->client_invited = 1; $event->save('event_clients_list'); } } ?> But i have to use a variable in my emailbody.inc which i'm able to get in the table-loop.
      So i do the including of the body inside my loop. But this doesn't work anymore. Page sends out the emails but is unable to change the value of the checkbox.
      I get no errors!
      I'm using ProTable
      <?php // event ID fron url query $eventID = $input->get('eventID','int'); // get event-page $event = $pages->get($eventID); // config $fromEmail = $event->event_mail_from; $fromName = $event->event_mail_from_name; $emailSubject = $event->event_subject; // loop through table and send out emails foreach($event->event_clients_list as $event_table_row) { // get client page $clientPage = $event_table_row->client_name; // get client email $clientEmail = $clientPage->email; // email html body ob_start(); include('./_inc/emailbody.inc'); $emailBody = ob_get_clean(); // make event-page editable $event->of(false); // if client isn't invited yet (checkbox not checked) if($event_table_row->client_invited == '') { // send email $m = new WireMail(); $m->to($clientEmail); $m->from($fromEmail, $fromName); $m->subject($emailSubject); $m->bodyHTML($emailBody); $m->send(); // mark client as invited $event_table_row->client_invited = 1; $event->save('event_clients_list'); } } ?>

      In general, is there an easy way to know which method should be used to access the API?
      For example, when _ini.php is used in the theme, it would seem you have to use wire()->addHookBefore(...). But on other sites where they used ready.php, I've seen it go straight to just doing $this->addHookAfter() even though there is no class or namespace set up in the ready.php file.
      So how do I know when I can do $this, or $wire, or wire() to access things? And any other variables I'm not aware of.
      Thanks!

      Hello there,
      I am building my website, which has a dozen projects with 10 images each. Basically, I need a filtering system but built in the most efficient and user-friendly way. You can see below that the images flow sideways so being hidden, JS lazy loading was a good tool, but I just wanted to try AJAX. Is it fit for this purpose or it's more for dynamic content?

      Hello forum,
      This is really a weird one, because front end editing works in a earlier website we did to a customer. 
      When I check the source code for current website it does initiate front end edit: 
      <span id=pw-edit-1 class='pw-edit pw-edit-InputfieldPageTitle' data-name=title data-page=1021 data-lang='1017' style='position:relative'><span class=pw-edit-orig>Tekijät</span><span class=pw-edit-copy id=pw-editor-title-1021 style='display:none;-webkit-user-select:text;user- select:text;' contenteditable>Tekijät</span></span>  But when I double click nothing happens (yes I'm 100% sure I'm superuser and logged in)
      I also tried to apply the front end with other methods than:
      $page->edit('title'); But didn't work either.
      We are using jquery 2.2.4, so it should not be a problem.
      Is this a bug related to current master or something else?
      Someone else having this problem as well?

      Hi everyone
      It seems that I don't fully understand the wireTempPath() function and I need some help.
      I use wireTempPath() to create a new location in assets/cache/WireTempDir and than copy a pdf from the assets/files/page folder to the new folder. I want the file to be accessible only for a limited time, that's why I use wireTempPath.
      The file seems to be copied to the right location, but gets deleted right afterwards, according to 
      As mentioned in the topic above, 
      $wireTempDir->setRemove(false); prevents the file to be deleted. But I like the file to be automatically deleted after a few days. So, how can I do that?
      My code so far (everything works, but the automatic removal of the tempDir folder):
      //generate and show download link $folder = time(); // timestamp as temporary folder $maxAge = (int) $settings->options_downloadlink_valid_hours * 3600; //tempDir wants maxAge as seconds $options = array( 'maxAge' => $maxAge ); $wireTempDir = wireTempDir($folder, $options); $wireTempDir->setRemove(false); $src_file = $page->ebook_download->filename; // Create a new directory in ProcessWire's cache dir if(wire('files')->mkdir($wireTempDir, $recursive = true)) { if(wire('files')->copy($src_file, $wireTempDir)){ //get subdirs from tempDir: $pos = strpos($wireTempDir, "WireTempDir"); $subdir = substr($wireTempDir, $pos, 100); $out .= "<p><a href='" . wire('pages')->get('template=passthrough')->httpUrl . "?file=" . $subdir . $page->ebook_download->basename . "' target='_blank'>$page->title</a></p>"; } } I appreciate any ideas - thanks!
      Oliver
