Follow the tutorial. You need to require Composer's autoloader.
If you check your PHP error log, you'll see the errors.

Pagination is not working when i get call history in twilio using laravel rest api. when i use page parameter with this then pagination is not working it give me save output as given me 1st page.
Postman parameters - Page:2
Thanks
I think Twilio's page() function will help you. Like read(), it accepts an array of options to narrow your search along with a pageSize parameter defaulting to 50 calls per page. (I believe the maximum value is 1000.)
Here is an example.
//Get all call logs. 20 per page
$calls = $twilio->calls->page( [], 20 );
$data = [];
foreach($calls as $call){
$data[] = $call->sid;
}
//You can access the previous and next page urls using the resource functions in the calls object return from twilio.
return response()->json(["prev" => $calls->getPreviousPageUrl(), "next" => $calls->getNextPageUrl(), "calls" => $data]);
I'm trying to do something really simple: just send a string to a server and save it as a txt file. I'm getting nothing at the moment - no txt file - nothing. I'm looking for really simple solutions. Here is what I have:
<script>
function submit()
{
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST", "test.php?d=Hey", true);
xmlhttp.setRequestHeader("Content-Type: text/plain");
xmlhttp.send();
}
</script>
<?php
$d = $_POST["d"];
$file = fopen("test.txt", "a");
fwrite($file, $d + "\n");
fclose($file);
?>
I need to save all rendered content (layout + view) in a variable to save it with Zend_Cache, I can't use Varnish, nginx or other software to do so. Currently I'm doing it like that:
$view->setTemplate('application/index/index');
$viewContent = $renderer->render($view);
$view = $this->getEvent()->getViewModel();
$view->content = $viewContent;
$content = $renderer->render($view);
Can anyone suggest me more elegant solution? Mb catching native render event with EventManager or some tricks with Response object or dispatch event? Would like to hear all suggestions.
Thanks!
Add two listeners to your Module class. one listener checks early, just after route if the match is one that's cached. The second listener waits for render and grabs the output to store it in cache:
namespace MyModule;
use Zend\Mvc\MvcEvent;
class Module
{
public function onBootstrap(MvcEvent $e)
{
// A list of routes to be cached
$routes = array('foo/bar', 'foo/baz');
$app = $e->getApplication();
$em = $app->getEventManager();
$sm = $app->getServiceManager();
$em->attach(MvcEvent::EVENT_ROUTE, function($e) use ($sm) {
$route = $e->getRouteMatch()->getMatchedRouteName();
$cache = $sm->get('cache-service');
$key = 'route-cache-' . $route;
if ($cache->hasItem($key)) {
// Handle response
$content = $cache->getItem($key);
$response = $e->getResponse();
$response->setContent($content);
return $response;
}
}, -1000); // Low, then routing has happened
$em->attach(MvcEvent::EVENT_RENDER, function($e) use ($sm, $routes) {
$route = $e->getRouteMatch()->getMatchedRouteName();
if (!in_array($route, $routes)) {
return;
}
$response = $e->getResponse();
$content = $response->getContent();
$cache = $sm->get('cache-service');
$key = 'route-cache-' . $route;
$cache->setItem($key, $content);
}, -1000); // Late, then rendering has happened
}
}
Just make sure you register a cache instance under cache-service in the service manager. You can update above example to check during the render event if the route is in the $routes array. Now you just check if the cache has the key, which might be slower than doing in_array($route, $routes) like during the render event.
I show a lot of thumbs on my homepage from youtube videos. I was using this function below to grab the thumb from a youtube url which works fast but it doesn't work for url's in the shortned form like youtu.be/JSHDLSKL.
function get_youtube_screen_link( $url = '', $type = 'default', $echo = true ) {
if( empty( $url ) )
return false;
if( !isset( $type ) )
$type = '';
$url = esc_url( $url );
preg_match("|[\\?&]v=([^&#]*)|",$url,$vid_id);
if( !isset( $vid_id[1] ) )
return false;
$img_server_num = 'i'. rand(1,4);
switch( $type ) {
case 'large':
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/0.jpg";
break;
case 'first':
// Thumbnail of the first frame
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/1.jpg";
break;
case 'small':
// Thumbnail of a later frame(i'm not sure how they determine this)
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/2.jpg";
break;
case 'default':
case '':
default:
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/default.jpg";
break;
}
if( $echo )
echo $img_link;
else
return $img_link;
}
So I tried to use Oembed to get the thumbs instead which works for all variations of the youtube url but it retrieves the 480px/360px thumb which causes a lot of cropping to get it down to the 120px/90px size I use to display them. The other issue was it caused my page speed to increase by 4 seconds which Im guessing is a problem with the way I'm implementing it. Here's how I call the thumb inside a loop.
<?php
require_once(ABSPATH.'wp-includes/class-oembed.php');
$oembed= new WP_oEmbed;
$name = get_post_meta($post->ID,'video_code',true);
$url = $name;
//As noted in the comments below, you can auto-detect the video provider with the following
$provider = $oembed->discover($name);
//$provider = 'http://www.youtube.com/oembed';
$video = $oembed->fetch($provider, $url, array('width' => 300, 'height' => 175));
$thumb = $video->thumbnail_url; if ($thumb) { ?>
<img src="<?php echo $thumb; ?>" width="120px" height="90px" />
<?php } ?>
So how should I be doing this to maximize efficiency?
I came across this page from youtube explaining their oembed support, They mentioned that they output to json format so I made a function that gets the json data and then enables you to use it.
Feel free to ask if you need more help.
<?php
$youtube_url = 'http://youtu.be/oHg5SJYRHA0'; // url to youtube video
function getJson($youtube_url){
$baseurl = 'http://www.youtube.com/oembed?url='; // youtube oembed base url
$url = $baseurl . $youtube_url . '&format=json'; // combines the url with format json
$json = json_decode(file_get_contents($url)); // gets url and decodes the json
return $json;
}
$json = getJson($youtube_url);
// from this point on you have all your data placed in variables.
$provider_url = $json->{'provider_url'};
$thumbnail_url = $json->{'thumbnail_url'};
$title = $json->{'title'};
$html = $json->{'html'};
$author_name = $json->{'author_name'};
$height = $json->{'height'};
$thumbnail_width = $json->{'thumbnail_width'};
$thumbnail_height = $json->{'thumbnail_height'};
$width = $json->{'width'};
$version = $json->{'version'};
$author_url = $json->{'author_url'};
$provider_name = $json->{'provider_name'};
$type = $json->{'type'};
echo '<img src="'.$thumbnail_url.'" />'; // echo'ing out the thumbnail image
Ok I came up with a solution from pieces of other questions. First we need to get the id from any type of url youtube has using this function.
function getVideoId($url)
{
$parsedUrl = parse_url($url);
if ($parsedUrl === false)
return false;
if (!empty($parsedUrl['query']))
{
$query = array();
parse_str($parsedUrl['query'], $query);
if (!empty($query['v']))
return $query['v'];
}
if (strtolower($parsedUrl['host']) == 'youtu.be')
return trim($parsedUrl['path'], '/');
return false;
}
Now we can get use YouTube Data API to get the thumbnail from the video id. Looks like this.
<?php
$vid_id = getVideoId($video_code);
$json = json_decode(file_get_contents("http://gdata.youtube.com/feeds/api/videos/$vid_id?v=2&alt=jsonc"));
echo '<img src="' . $json->data->thumbnail->sqDefault . '" width="176" height="126">';
?>
The problem is that is causing an extra 2 seconds load time so I simply use the $vid_id and place it inside http://i3.ytimg.com/vi/<?php echo $vid_id; ?>/default.jpg which gets rid of the 2 seconds added by accessing the youtube api.
I am using tmhOAuth.php / class to login into twitter. I have been successful in logging in and sending a tweet.
When I go to use the friends.php script, I am having some problems inserting into my database. I do believe that my problem lies some where with the $paging variable in the code. Because it is looping only seven times. I am following 626 people so my $ids is 626 and then $paging is 7.
When I run the php in a web browser, I am only able to extract 7 of the followers (ie following user #626,following user 526,following user 426...) It seem to be echoing the last user on each page request. This due in part to requesting 100 user ids at a time, via the PAGESIZE constant. When I adjust the $paging with different number such as the number 626 I get {"errors":[{"code":17,"message":"No user matches for specified terms"}]}
Unfortunately, I suspect this is fairly simple php looping problem, but after the amount of time I have spent trying to crack this I can no longer think straight.
Thanks in advance.
define('PAGESIZE', 100);
require 'tmhOAuth.php';
require 'tmhUtilities.php';
if ($tmhOAuth->response['code'] == 200) {
$data = json_decode($tmhOAuth->response['response'], true);
$ids += $data['ids'];
$cursor = $data['next_cursor_str'];
} else {
echo $tmhOAuth->response['response'];
break;
}
endwhile;
// lookup users
$paging = ceil(count($ids) / PAGESIZE);
$users = array();
for ($i=0; $i < $paging ; $i++) {
$set = array_slice($ids, $i*PAGESIZE, PAGESIZE);
$tmhOAuth->request('GET', $tmhOAuth->url('1/users/lookup'), array(
'user_id' => implode(',', $set)
));
// check the rate limit
check_rate_limit($tmhOAuth->response);
if ($tmhOAuth->response['code'] == 200) {
$data = json_decode($tmhOAuth->response['response'], true);
if ($tmhOAuth->response['code'] == 200) {
$data = json_decode($tmhOAuth->response['response'], true);
$name = array();
foreach ($data as $val)
{
$name = $data[0]['screen_name'];
}
echo "this is the screen name " .$name. "\n";
$users += $data;
} else {
echo $tmhOAuth->response['response'];
break;
}
}
var_dump($users);
?>
The data I am trying to echo, then parse and insert into database is the standard twitter JSON data, so I won't include this in the message. Any help would be
Problem solved:
foreach ($data as $val)
{
$name = $val['screen_name'];
echo "this is the screen name " .$name. "\n";
$users[] = $name;
}
