I have a code that can get the Amazon product price if you gave it's "ASIN" (It's Amazon product identification number)... below you can find the code (I don't think there is a need to read the code anyway).
<?php
class AmazonAPI {
var $amazon_aff_id;

var $error_message;
var $error=0;
public function __construct($affid, $access, $secret)
{
$this->amazon_aff_id = $affid;
$this->amazon_access_key = $access;
$this->amazon_secret_key = $secret;
}
public function build_url()
{
$url = "http://webservices.amazon.com/onca/xml?";
$this->response_groups = str_replace(",", "%2C", $this->response_groups);
$url_params = "AWSAccessKeyId=" . $this->amazon_access_key;
$url_params .= "&AssociateTag=" . $this->amazon_aff_id;
if(!empty($this->itemID)) {
$url_params .= "&ItemId=" . $this->itemID;

public function get_item_price($product)
{
$price = 0;
if(isset($product->LowestNewPrice)) {
$price = $product->LowestNewPrice->Amount;
} elseif(isset($product->LowestUsedPrice)) {
$price = $product->LowestUsedPrice->Amount;
} elseif(isset($product->LowestCollectiblePrice)) {
$price = $product->LowestCollectiblePrice->Amount;

public function get_item_data()
{
if($this->check_for_errors()) return null;
$product = $this->xml->Items->Item;
$item = new STDclass;
$item->detailedPageURL = $product->DetailPageURL;
$item->link = "https://www.amazon.com/gp/product/".$this->itemID."/?tag=" . $this->amazon_aff_id;
$item->title = $product->ItemAttributes->Title;
$item->smallImage = $product->SmallImage->URL;
$item->mediumImage = $product->MediumImage->URL;
$item->largeImage = $product->LargeImage->URL;
$item->price = $this->get_item_price($product->OfferSummary);
return $item;
}
}
?>
Then i echo the price with this code
$amazon = new AmazonAPI("associate-id", "access-key", "secret-key");
$item = $amazon->item_lookup("ASIN")->get_item_data();
echo $item->price;
Now if i have a csv sheet like this
https://ibb.co/dHS4EK
can i update the prices on column D and E given the asin found on column B and C,
so for example the value of cell D2 will get it using the following code
$amazon = new AmazonAPI("associate-id", "access-key", "secret-key");
$item = $amazon->item_lookup(Value on cell D2)->get_item_data();
echo $item->price;
then save the csv file after updating it's prices, is there a simple easy way to do that in maybe php especially that i'm very new to coding?
Edit 1: I need the csv file to import it using WooCommerce import tool which only accept csv files
Thanks in advance
What you have to do is:
Parse the CSV file into an array. You can use PHP functions for that like str-getcsv
Find the correct line inside the array with either array_filter or a simple foreach loop.
Update the respective value with the new price
Create a CSV file from the array with fputcsv

i am trying to make my small websocket php class in which i wanted to make functions like onopen onmessage etc like node js [i know there are other libraries out there but i wanted to learn it myself].so far i am able to successfully recieve message from js websocket to php with this code below
<?php
$host = "localhost";
$port = 8001;
$sockets=array();
function sendAll($connections,$msg){
foreach ($connections as $each) {
send($each,$msg);
}
}
function send($client,$msg){
$msg = chr(129) . chr(strlen($msg)) . $msg;
socket_write($client,$msg,strlen($msg));
}
function handshake($client){
$request = socket_read($client, 5000);
preg_match('#Sec-WebSocket-Key: (.*)\r\n#', $request, $matches);
$key = base64_encode(pack(
'H*',
sha1($matches[1] . '258EAFA5-E914-47DA-95CA-C5AB0DC85B11')
));

if($client != false){
usleep(100);

array_push($sockets,$client);
print_r($sockets);
}
else{
if(count($sockets) > 0){
foreach ($sockets as $each) {
$msg = socket_read($each,5000);
if($msg != false){
filter($msg);
// send($each,"testing");
}
}
}
}
}
function filter($msg){
$msg = unpack("c*",$msg);
foreach ($msg as $value) {
echo chr($value);
}
// print_r($msg);
}
?>
after some research i found that websocket sends message in binary. i cant convert that message into plain text. i dont know which language or format that data is sent into.tell me please which format is it and how to read it as plain text sample picture below
finally i find the way to decode from this website
its actually masked which needed to be unmasked . here i found a function from a website all i have to do is to read that scarmled text is unmask with below custom function
function unmask($text) {
$length = ord($text[1]) & 127;
if($length == 126) {
$masks = substr($text, 4, 4);
$data = substr($text, 8);
}
elseif($length == 127) {
$masks = substr($text, 10, 4);
$data = substr($text, 14);
}
else {
$masks = substr($text, 2, 4);
$data = substr($text, 6);
}
$text = "";
for ($i = 0; $i < strlen($data); ++$i) {
$text .= $data[$i] ^ $masks[$i%4];
}
return $text;
}
I am trying to pass a php array to a javascript variable as an object to use in google maps on the same page/file. I am not able to send out an alert when testing the array in javascript.
PHP
while( $row = $query->fetch_assoc() ){
$street_address = $row['street_address'];
$zip = $row['zip'];
$state = $row['state'];
$lat = $row['lat'];
$lng = $row['lng'];
$test = $row['sellerDB_test'];
$firstName = $row['first_name'];
$lastName = $row['last_name'];
$email = $row['email'];
$phone = $row['phone'];
/* Each row is added as a new array */
$locations = array( 'streetAddress'=>$street_address, 'state'=>$state, 'zip'=>$zip, 'lat'=>$lat, 'lng'=>$lng, 'test'=>$test, 'first name'=>$firstName, 'last name'=>$lastName, 'email'=>$email, 'phone'=>$phone);
JS
var map;
var Markers = {};
var infowindow;
var locations = '<?php echo json_encode($locations); ?>';
var location = JSON.parse(loactions);
alert(locations[0]);
I am getting this error
Uncaught ReferenceError: loactions is not defined
at account:299
#Ghost is right. I did not notice that the $locations is inside while loop. So You should define $locations = []; before while loop.
And then keep adding multiple records from while loop. So the updated code should be like:
$locations = [];
while( $row = $query->fetch_assoc() ){
$street_address = $row['street_address'];
$zip = $row['zip'];
$state = $row['state'];
$lat = $row['lat'];
$lng = $row['lng'];
$test = $row['sellerDB_test'];
$firstName = $row['first_name'];
$lastName = $row['last_name'];
$email = $row['email'];
$phone = $row['phone'];
/* Each row is added as a new array [] */
$locations[] = array( 'streetAddress'=>$street_address, 'state'=>$state, 'zip'=>$zip, 'lat'=>$lat, 'lng'=>$lng, 'test'=>$test, 'first name'=>$firstName, 'last name'=>$lastName, 'email'=>$email, 'phone'=>$phone);
}
And after this, you should put the JS code snippet.
And use it like this:
JS cpde:
var map;
var Markers = {};
var infowindow;
var locations = <?php echo json_encode($locations); ?>;
var location = JSON.parse(loactions);
alert(location.streetAddress);
I am working on Japanese language web site, and using this code for words limit, it is working when I paste English sentence but not working with Japanese words .
function content($num) {
$theContent = get_the_content();
$output = preg_replace('/<img[^>]+./','', $theContent);
$output = preg_replace( '/<blockquote>.*<\/blockquote>/', '', $output );
$output = preg_replace( '|\[(.+?)\](.+?\[/\\1\])?|s', '', $output );
$limit = $num+1;
$content = explode(' ', $output, $limit);
array_pop($content);
$content = implode(" ",$content)."...";
echo $content;
}
<?php content('15'); ?>
Can any body help me, and one thing is that I am using xeory_extension theme.
The problem is that Japanese characters are multibyte (Hiragana and Katakana characters are stored on 3 bytes in UTF-8), so you'll have to use special php multibytes string functions to manipulate strings that contains Japanese characters.
Sadly PHP doesn't provide a mb_explode function out of the box. Though some people worked on that, using mb_strlen and mb_substr to build up that missing function.
The following code is note mine, it comes from the fetus-hina mb_explode gist:
function mb_explode($delimiter, $string, $limit = -1, $encoding = 'auto') {
if(!is_array($delimiter)) {
$delimiter = array($delimiter);
}
if(strtolower($encoding) === 'auto') {
$encoding = mb_internal_encoding();
}
if(is_array($string) || $string instanceof Traversable) {
$result = array();
foreach($string as $key => $val) {
$result[$key] = mb_explode($delimiter, $val, $limit, $encoding);
}
return $result;
}
$result = array();
$currentpos = 0;
$string_length = mb_strlen($string, $encoding);
while($limit < 0 || count($result) < $limit) {
$minpos = $string_length;
$delim_index = null;
foreach($delimiter as $index => $delim) {
if(($findpos = mb_strpos($string, $delim, $currentpos, $encoding)) !== false) {
if($findpos < $minpos) {
$minpos = $findpos;
$delim_index = $index;
}
}
}
$result[] = mb_substr($string, $currentpos, $minpos - $currentpos, $encoding);
if($delim_index === null) {
break;
}
$currentpos = $minpos + mb_strlen($delimiter[$delim_index], $encoding);
}
return $result;
}
Then just use it the same way you use explode:
$content = mb_explode(' ', $output, $limit);
And for implode, you shouldn't have any issue.
This worked for me
function custom_short_excerpt($excerpt){
$limit = 200;
if (strlen($excerpt) > $limit) {
return substr($excerpt, 0, strpos($excerpt, ' ', $limit));
}
return $excerpt;
}
add_filter('the_excerpt', 'custom_short_excerpt');
When I pass data into my file upload controller, it is giving an error of undefined offset: 1.
function TestFileUpload() {
$i=0;
if(!isset($_FILES[$i]) ) {
echo "No file is being uploaded";
}
else {
$x = $_FILES[$i]['name'];
$xx = explode('.', $x);
$config['upload_path'] = 'MRS-files\Upload_files';
$config['allowed_types'] = 'xls|doc|jpg|png|gif|pdf';
$this->load->library('upload',$config);
$count = count($_FILES[$i]['name']). ' ';
while ($i <= 4 )
{
echo $count;
$x = $_FILES[$i]['name'];
$xx=explode(".", $x);
echo $_FILES[$i]['name'].' '.$_FILES[$i]['type'].' '.$_FILES[$i]['size'] ;
$this->upload->initialize($config);
$_FILES['up']['name'] = $_FILES[$i]['name'];
$_FILES['up']['tmp_name'] = $_FILES[$i]['tmp_name'];
$_FILES['up']['type'] = $_FILES[$i]['type'];
$_FILES['up']['size'] = $_FILES[$i]['size'];
if ( ! $this->upload->do_upload('up')) {
//error on uploading
echo str_replace('','',$this->upload->display_errors()); //temporary commented no use cause of redirect to homepage
//$this->cancelREC();
exit();
}
else{
$data = array('upload_data' => $this->upload->data());
$this->new_development_model->insertonAttachments($data['upload_data']);
$i++;
}
}
}
}
It's probably related cause you need to check in your loop if $_FILES[$i] is defined.
You do this but only one time, when $i = 0.
I even think that if you check in the loop, you wont need to do
if(!isset($_FILES[$i]) ) {
echo "No file is being uploaded";
}
else { /*...*/ }
before the loop
I'm trying to create a gameserver query for my website, and I want it to load the content, save it, and echo it later. However, it doesn't seem to be echoing. It selects the element by ID and is supposed to echo the content of the VAR.
Here's my HTML code:
<center><div id="cstrike-map"><i class="fa fa-refresh fa-spin"></i> <b>Please wait ...</b><br /></div>
JavaScript:
<script type="text/javascript">
var map = "";
var hostname = "";
var game = "";
var players = "";
$.post( "serverstats-cstrike/cstrike.php", { func: "getStats" }, function( data ) {
map = ( data.map );
hostname = ( data.hostname );
game = ( data.game );
players = ( data.players );
}, "json");
function echoMap(){
document.getElementByID("cstrike-map");
document.write("<h5>Map: " + map + "</h5>");
}
</script>
PHP files:
query.php
/* SOURCE ENGINE QUERY FUNCTION, requires the server ip:port */
function source_query($ip)
{
$cut = explode(":", $ip);
$HL2_address = $cut[0];
$HL2_port = $cut[1];
$HL2_command = "\377\377\377\377TSource Engine Query\0";
$HL2_socket = fsockopen("udp://".$HL2_address, $HL2_port, $errno, $errstr,3);
fwrite($HL2_socket, $HL2_command); $JunkHead = fread($HL2_socket,4);
$CheckStatus = socket_get_status($HL2_socket);
if($CheckStatus["unread_bytes"] == 0)
{
return 0;
}

{
$x++;
$result.= substr($HL2_stats, $x, 1);
}

return $result;

$sinfo = urldecode($string);
$sinfo = explode('|||',$sinfo);
$info['hostname'] = $sinfo[0];

cstrike.php
include('query.php');
$ip = 'play1.darkvoidsclan.com:27015';
$query = source_query($ip); // $ip MUST contain IP:PORT
$q = format_source_query($query);
$host = "<h5>Hostname: ".$q['hostname']."</h5>";
$map = "<h5>Map: ".$q['map']."</h5>";
$game = "<h5>Game: ".$q['game']."</h5>";
$players = "Unknown";
$stats = json_encode(array(
"map" => $map,
"game" => $game,

You need to display the response in the $.post callback:
$.post( "serverstats-cstrike/cstrike.php", { func: "getStats" }, function( data ) {
$("#map").html(data.map);
$("#hostname").html(data.hostname);
$("#game").html(data.game);
$("#players").html(data.players);
}, "json");
You haven't shown your HTML, so I'm just making up IDs for the places where you want each of these things to show.
There are some things that I can't understand from your code, and echoMap() is a bit messed up... but assuming that your php is ok it seems you are not calling the echomap function when the post request is completed.
Add echoMap() right after players = ( data.players );
If the div id you want to modify is 'cstrike-map' you could use jQuery:
Change the JS echoMap to this
function echoMap(){
$("#cstrike-map").html("<h5>Map: " + map + "</h5>");
}
So what I did was I had to echo the content that I needed into the PHP file, then grab the HTML content and use it.
That seemed to be the most powerful and easiest way to do what I wanted to do in the OP.
<script type="text/javascript">
$(document).ready(function(){
$.post("stats/query.cstrike.php", {},
function (data) {
$('#serverstats-wrapper-cstrike').html (data);
$('#serverstats-loading-cstrike').hide();
$('#serverstats-wrapper-cstrike').show ("slow");
});
});
