Hi Does anyone know how I can connect a thermal printer from my Samsung tab to print to the printer? The printer is not a Bluetooth printer. It is connected to the system via a cable. I have checked and it seems the printer does not have an ip address either. Was thinking I could connect via the system ip address when shared. I have tried many android app including printshare and mobiprint rawbt but I wasn't able to connect the printer to the tab. I don't know if I was doing something wrong though. If any has done something like that, please I'd like to know. Thanks

I have php code that uses mp3 audio files stored in a database for the user to listen to. The page loads and the audio controls work and the files play on a desktop and laptop just fine. When trying to play a file on an android or IPhone, when you press the play (or any other control) nothing happens. It acts like the page is static. There is a home button on the webpage and it works so I know the page is interactive. Below is the code. I would appreciate any help. Thank you. <?php $sermons = $database->select("sermon","*");; foreach( $sermons as $sermon ) { $audio_file = 'http://xxxxxxx.com/sermons/'.$sermon['file_name']; $player = "<audio id='sermon_'$sermon[id] controls> <source src='$audio_file' type='audio/mpeg'> <source src='$audio_file' type='audio/mp3'> Your browser does not support the audio element. </audio>"; echo "<tr> <td>$sermon[sermon_date]</td> <td>$sermon[title]</td> <td>$sermon[speaker]</td> <td>$player</td> </tr>"; } ?>

Hi everyone, I'm new here and i'm also new with coding in PHP. I have written one Restful Api based on one tutorial and i need Restful Api for connecting my Android application to server. I need some help with making this to work. I need to update user details. This is the code i'm using: class DbHandler { public function updateUser($id, $name) { $stmt = $this->conn->prepare("UPDATE users SET name = ? WHERE id = ?"); $stmt->bind_param("is", $id, $name); $stmt->execute(); $num_affected_rows = $stmt->affected_rows; $stmt->close(); return $num_affected_rows > 0; } } This is preparation statement for updating a existing user. Now here is a fragment of code from index.php where i'm calling all methods: $app->put('/user/:id', 'authenticate', function($id) use($app) { verifyRequiredParams(array('name')); global $id; $name = $app->request->put('name'); $db = new DbHandler(); $response = array(); $result = $db->updateUser($id, $name); if ($result) { $response["error"] = false; $response["message"] = "User updated successfully"; } else { $response["error"] = true; $resopnse["message"] = "User failed to update. Please try again"; } echoRespnse(200, $response); }); When i try to send request, i'm getting only this: { "error": true } Any help would be appreciated. Thanks.

I have a php application that serves pdf downloads. It works fine on all devices and browsers with one small but really annoying side-effect (edge-case for sure) When I look at my download logs anytime the download is triggered from Chrome on Android it is called twice! Bizarre behavior and I can't figure it out. Some background: The download is a pdf that get's created on the fly. All requests get processed through my index.php controller. I was serving the request with javascript via: window.open('export?file=something_to_inform_the_controller'); Works great in all browsers and devices but android chrome triggers this twice. So I got wise and though maybe a direct link would work better: <a target="_blank" href="http://mysite.com/export?file=abc123" download="file.pdf">DL link</a> or <a target="_blank" href="http://mysite.com/export?file=abc123">DL link</a> or <a target="_self" href="http://mysite.com/export?file=abc123" download="file.pdf">DL link</a> or <a target="_self" href="http://mysite.com/export?file=abc123">DL link</a> Nope, none of these flavors prevents android/chrome from double downloading. Then I researched my php header settings and tried: content-disposition: inline vs. content-disposition: attachment with no success Note, the download is logged when the controller processes the request for the download. I have duplicated download events for all downloads on android/chrome. It's strange that I have not found a solution online for this or maybe I'm overlooking something silly. Any ideas?
