Is there an easy way to update CSV with an API data?

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 $amazon_access_key;
var $amazon_secret_key;
var $url_params;
var $itemID;
var $xml;
var $operation;
var $signature;
var $response_groups = "Small,Images,OfferSummary";
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;
}
$url_params .= "&Operation=" . $this->operation;
$url_params .= "&ResponseGroup=" . $this->response_groups;
$url_params .= "&Service=AWSECommerceService";
$url_params .= "&Timestamp=" . rawurlencode(gmdate("Y-m-d\TH:i:s\Z"));
$url_params .= "&Version=2013-08-01";
$this->url_params = $url_params;
$url .= $url_params;
$url .= "&Signature=" . $this->generate_signature();
return $url;
}
public function generate_signature()
{
$this->signature = base64_encode(hash_hmac("sha256",
"GET\nwebservices.amazon.com\n/onca/xml\n" . $this->url_params,
$this->amazon_secret_key, True));
$this->signature = str_replace("+", "%2B", $this->signature);
$this->signature = str_replace("=", "%3D", $this->signature);
return $this->signature;
}
public function item_lookup($id)
{
$this->operation = "ItemLookup";
$this->itemID = $id;
$url = $this->build_url();
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$output = curl_exec($ch);
curl_close($ch);
$this->xml = simplexml_load_string($output);
return $this;
}
public function check_for_errors()
{
if(isset($this->xml->Error)) {
$this->error_message = $this->xml->Error->Message;
$this->error = 1;
}
if(isset($this->xml->Items->Request->Errors)) {
$this->error_message = $this->xml->Items->Request->Errors->Error->Message;
$this->error = 1;
}
return $this->error;
}
public function get_item_price($product)
{
$price = 0;
if(isset($product->LowestNewPrice)) {
$price = $product->LowestNewPrice->Amount;
} elseif(isset($product->LowestUsedPrice)) {
$price = $product->LowestUsedPrice->Amount;
} elseif(isset($product->LowestCollectiblePrice)) {
$price = $product->LowestCollectiblePrice->Amount;
} elseif(isset($product->LowestRefurbishedPrice)) {
$price = $product->LowestRefurbishedPrice->Amount;
}
return $price;
}
public function get_item_data()
{
if($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

Input type file not working in CodeIgniter

This is the controller. I update the image but I think input type file not accept file or not send the file to the controller so my code was not working well. I think controller code is true.
class OurTeam extends CI_Controller {
public function UpdateTeam()
{
$config['image_library'] = 'gd2';
$config['upload_path'] = '../employeephoto/';
$config['source_image'] ='employeephoto/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 12024;
$config['width'] = 300;
$config['height'] = 150;
$this->load->library('upload', $config);
$img = $_FILES['fileupdate']['name'];
if($img)
{
if (!$this->upload->do_upload('fileupdate'))
{
$error = array('error' => $this->upload->display_errors());
}
else
{
$data = array('upload_data' => $this->upload->data());
$file_name=($this->upload->data('file_name'));
$this->load->model('OurTeamModel');
$id= $_POST['id'];
$removeimg = $this->OurTeamModel->SelectById($id);
echo $imgpath = 'employeephoto/'.$removeimg[0]->img;
if(file_exists($imgpath))
{
unlink($imgpath);
}
else
{
echo "no";
}
$this->OurTeamModel->UpdateOurTeam($file_name);
$config['image_library'] = 'gd2';
$config['upload_path'] = '../employeephoto/'.$file_name;
$config['source_image'] = '../employeephoto/'.$file_name;
$config['maintain_ratio'] = false;
$config['allowed_types'] = 'gif|jpg|png';
$config['width'] = 660;
$config['height'] = 300;
$this->load->library('image_lib', $config);
$this->image_lib->clear();
$this->image_lib->initialize($config);
$ok = $this->image_lib->resize();
}
}
else
{
$this->load->model('OurTeamModel');
$this->OurTeamModel->UpdateOurTeamRecord();
}
redirect('admin/OurTeam');
}
}
This is view page
<?php echo form_open_multipart('admin/OurTeam/UpdateTeam');?>
<input type="file" name="fileupdate" size="20" id="fileupdate">
<input type="submit" value="Save" >
</form>

Please change to
From:

$config['upload_path'] = '../employeephoto/';
$config['source_image'] ='employeephoto/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 12024;
$config['width'] = 300;
$config['height'] = 150;
TO:
$config['upload_path'] = './employeephoto/';
$config['allowed_types'] = 'gif|jpg|png|doc|txt';
$config['max_size'] = 1024 * 8;
$config['encrypt_name'] = TRUE;
I have checked your code. Please do one thing this article and follow step by step. Hope this will make sense.
https://www.tutorialspoint.com/codeigniter/codeigniter_file_uploading.htm
Here is the step by step explanation how to upload a file in CodeIgniter.

Try this and let me know what is outputting (maybe take a printsrc and upload to imgur):

how to create zip from images base64 php

var imgAlums = window.document.getElementsByClassName("imgAlu");
var photos= [];
for (var i = 0; i < imgAlums.length; i++) {
photos.push(imgAlums[i].currentSrc);
}
//the photos array is filled //photos[0]=
data:image/;base64,/9j/4AAQSkZJRgABAQAAAQA...;
//photos[1]=data:image/;base64,/9j/4AAFWEJDKWMDCIWUEIOD...;
$.ajax({
type: 'POST',
url: '<?= URL_PROYECTO_SEGURO ?>/panel/assets/php/generateZipPhotos.php',
data: {"photos": JSON.stringify(photos)},
success: function (data) {
console.log(data);
alert("Operacion realizada con exito");
}
});
PHP code:
$nameZip = "test.zip";
$zip = new ZipArchive();
$zip->open($nameZip, ZipArchive::OVERWRITE);
$zip->addEmptyDir("Photos");
$photos= json_decode($_POST["photos"], true);
for ($i = 0; $i < count($photos); $i++) {
$data = $photos[$i];
$data = str_replace('data:image/png;base64,', '', $data);
$data = str_replace(' ', '+', $data);
$data = base64_decode($data);
$zip->addFromString("Photos/Photo" . $i . ".png", $data);
}
$zip->close();
header("Content-type: application/zip");
header("Content-Disposition: attachment; filename=$nameZip");
header("Content-Transfer-Encoding: binary");
readfile($nameZip);
unlink($nameZip);
But does not generate the zip file correctly.
[edit]The zip file is generated but this has nothing inside. The problem is when you write in the zip file. The photo is misspelled

PHP Image Upload Not Resizing When Sent Via JS

I am running into issues when uploading an image sent to PHP via JS. I can upload the image fine, but I would to resize the image before moving it to it's new destination. I can also rename the image without any issues. It's really just the resizing that is the issue here.
After a lot of searching I have seen a lot of questions regarding this on SO, which is how I got to where I am now, but not one that answers this 100%. If you know of a question/answer already on SO please link me to the correct article.
Any help is much appreciated, thanks.
Here is the JS
var test = document.querySelector('#afile');
test.addEventListener('change', function() {
var file = this.files[0];
var fd = new FormData();
fd.append('afile', file);
// These extra params aren't necessary but show that you can include other data.
fd.append('id', burgerId);
var xhr = new XMLHttpRequest();
// why wont this work in the actions directory?
xhr.open('POST', 'actions/upload.php', true);
xhr.upload.onprogress = function(e) {
if (e.lengthComputable) {
var percentComplete = (e.loaded / e.total) * 100;
var uploadProcess = document.getElementById('uploadProcess');
uploadProcess.setAttribute('style', 'width: ' + percentComplete + '%;');
// uploadProcess.innerHTML = parseInt(percentComplete) + '% uploaded';
}
};
xhr.onload = function() {
if (this.status == 200) {
var resp = JSON.parse(this.response);
image = 'img/' + resp.newFileName;
sessionStorage.setItem('burgerLoc', image);
var image = document.createElement('img');
image.src = resp.dataUrl;
document.body.appendChild(image);
};
};
xhr.send(fd);
// upImage(id)
}, false);
Here is the markup
<input type="file" name="afile" id="afile" accept="image/*"/>
Here is the PHP
$image = $_FILES['afile']['name'];
$image_tmp = $_FILES['afile']['tmp_name'];
$image_type = $_FILES['afile']['type'];
function getName($str) {
$parts = explode('.',$str);
$imgName = str_replace(' ', '_',$parts[0]);
return $imgName;
}
function getExtension($str) {
$parts = explode('.',$str);
$ext = $parts[1];
return $ext;
}
$image_name = stripslashes($image);
$name = getName($image_name);
$image_ext = getExtension($image_name);
$ext = strtolower($image_ext);
if($ext == 'jpg' || $ext == 'jpeg' ) {
$ext = 'jpg';
$src = imagecreatefromjpeg($image_tmp);
} else if($ext == 'png') {
$src = imagecreatefrompng($image_tmp);
} else {
$src = imagecreatefromgif($image_tmp);
}
$file_content = file_get_contents($image_tmp);
$data_url = 'data:' . $image_type . ';base64,' . base64_encode($file_content);
list($width,$height) = getimagesize($image_tmp);
// width of the main image
$new_width = 748;
$new_height = ($height / $width) * $new_width;
$img_dest = imagecreatetruecolor($new_width,$new_height);
imagecopyresampled($img_dest,$src,0,0,0,0,$new_width,$new_height,$width,$height);
// rename the file
$new_file_name = strtolower($_REQUEST['id'] . '.' . $ext);
$new_file_location = '../img/' . $new_file_name;
imagejpeg($img_dest,$new_file_name,100);
move_uploaded_file($image_tmp, $new_file_location);
imagedestroy($src);
imagedestroy($img_dest);
$json = json_encode(array(
'dataUrl' => $data_url,
'extension' => $ext,
'id' => $_REQUEST['id'],
'name' => $image,
'newFileName' => $new_file_name,
'type' => $image_type
));
echo $json;

I would maybe try installing ImageMagick in your linux distribution and try to use this function to resize the image
http://php.net/manual/en/imagick.resizeimage.php
I have reproduced your script on my webserver... I have made modifications and came up with this.
The most significant modification is that I am using exact paths in the file locations, and that I am moving the tmp file to a real file, load that real file, resize that real file instead of trying it to do with the tmp uploaded file.
PHP:
<?php
$image = $_FILES['afile']['name'];
$image_tmp = $_FILES['afile']['tmp_name'];
$image_type = $_FILES['afile']['type'];
function getName($str) {
$parts = explode('.',$str);
$imgName = str_replace(' ', '_',$parts[0]);
return $imgName;
}
function getExtension($str) {
$parts = explode('.',$str);
$ext = $parts[1];
return $ext;
}
$image_name = stripslashes($image);
$name = getName($image_name);
$image_ext = getExtension($image_name);
$ext = strtolower($image_ext);
$outputfolder = "/var/www/html/wp-content/";
$new_file_name = strtolower($_REQUEST['id'] . '.' . $ext);
$new_file_location = $outputfolder.$new_file_name;
move_uploaded_file($image_tmp, $new_file_location);
if($ext == 'jpg' || $ext == 'jpeg' ) {
$ext = 'jpg';
$src = imagecreatefromjpeg($new_file_location);
} else if($ext == 'png') {
$src = imagecreatefrompng($new_file_location);
} else {
$src = imagecreatefromgif($new_file_location);
}
list($width,$height) = getimagesize($new_file_location);
// width of the main image
$new_width = 748;
$new_height = ($height / $width) * $new_width;
$img_dest = imagecreatetruecolor($new_width,$new_height);
imagecopyresampled($img_dest,$src,0,0,0,0,$new_width,$new_height,$width,$height);
$resizedLocation = $outputfolder."resized_".$new_file_name;
imagejpeg($img_dest,$resizedLocation,100);
imagedestroy($src);
imagedestroy($img_dest);
$file_content = file_get_contents($resizedLocation);
$data_url = 'data:image/jpeg;base64,' . base64_encode($file_content);
$json = json_encode(array(
'dataUrl' => $data_url,
'extension' => $ext,
'id' => $_REQUEST['id'],
'name' => $image,
'newFileName' => $new_file_name,
'type' => $image_type
));
echo $json;
?>
Your HTML/JS stays untouched.
Now this works for me flawlessly, the only thing you have to make sure
the $outputfolder is writeable by the linux user under which the webeserver executing the php script is runnging (typically web-data...)
My web server:
CentOS Linux release 7.0.1406 (Core)
php.x86_64 5.4.16-23.el7_0.3
apache x86_64 2.4.6
