i'm recovering images from an xml file.
I save them correctly in the directory but I would like to compress them in order to reduce their weight.
How can I do?
I enclose the code
$uno = 1; //
if (!file_exists(__DIR__ .'/../web/media/imm/imm'.$idImmobile.'')) {
mkdir(__DIR__ .'/../web/media/imm/imm'.$idImmobile.'', 0777, true);
}
foreach ($empl->images->image as $images){
$urlimg{$num} = $images->url;enter code here
#$rawImage = file_get_contents($urlimg{$num});
if($rawImage){
file_put_contents(__DIR__ ."/../web/media/imm/imm".$idImmobile."/photo_".$uno++.".jpg",$rawImage);
echo 'Image Saved';
}
else
{
echo 'Error Occured';
}
}

I have a webform with a file upload field. I need do one of two things. Either upload files into a subfolder inside the private area, OR, add a prefix to the filename that the user is uploading. The user can upload several files. The webform editor allows you to 'Rename' the file and use tokens for this, but I don't see any way of preserving the original file name. I can hack getFileDestinationUri() in WebformManagedFileBase.php to do what I want, but obviously I would rather not do that. Am I missing something?
It turns out that you can use the drupal form alter hook to alter the destination. I had thought of this but felt if was unlikely to work. It does.
Below is MY code solution: (I may be missing container types)
function _mymodule_fix_elements(&$elements) {
foreach ($elements as $key => &$element) {
if (strpos($key, '#') !== 0) {
if (is_array($element)) {
if (isset($element['#type'])) {
if (($element['#type'] == 'fieldset') ||
($element['#type'] == 'webform_flexbox') ||
($element['#type'] == 'container')) {
_mymodule_fix_elements($element);
} else if ($element['#type'] == 'managed_file') {
$pattern = $element['#upload_location'];
if (strpos($pattern, 'private:') === 0) {
$element['#upload_location'] = $pattern . '/' . $key;
}
}
}
}
}
}
}
function mymodule_form_alter(&$form, &$form_state, $id) {
if (strpos($id, 'webform_') === 0) {
_mymodule_fix_elements($form['elements']);
}
}
I have installed latest version of magento in my localhost.
After login to admin panel dashboard keeps loading.
Here is the image-
Please help to solve this error.
First Go to magento root directory then :
vendor/magento/framework/view/element/tempalate/file/validator.php (dont exactly copy this url just follow this path)
open this file using any editor and change this line
$realPath = $this->fileDriver->getRealPath($path); //you can comment this out
with this one
$realPath = str_replace('\\','/',$this->fileDriver->getRealPath($path));
then goto to
app/etc/di.xml
and search for view_preprocessed
you will find a whole line like this :
Magento\Framework\App\View\Asset\MaterializationStrategy\Symlink
and change the Symlink with Copy
Magento 2.3
go to \lib\internal\Magento\Framework\View\Element\Template\File
go to the function isPathInDirectories and replace the function with following
protected function isPathInDirectories($path, $directories)
{
if (!is_array($directories)) {
$directories = (array)$directories;
}
//$realPath = $this->fileDriver->getRealPath($path);
$realPath = str_replace('\\','/',$this->fileDriver->getRealPath($path));
foreach ($directories as $directory) {
//$realDirectory = $this->fileDriver->getRealPath($directory);
$realDirectory = str_replace('\\','/',$this->fileDriver->getRealPath($directory));
if ($realDirectory && 0 === strpos($realPath, $realDirectory)) {
return true;
}
}
return false;
}
go to app/etc/di.xml then search for view_preprocessed
you will find a whole line like this :
Magento\Framework\App\View\Asset\MaterializationStrategy\Symlink and change to Magento\Framework\App\View\Asset\MaterializationStrategy\Copy
#1. go to vendor/magento/framework/View/Element/Template/File/Validator.php#

I need to create a system that will be able to output a template (a zip with an index.html with all js, css, img etc files as required) based on a set of options (include menu 1, use small footer etc).
So I can put code blocks in so it would not be hard to actually output to the browser the required look, but what if I want to save the rendered html (and this means we would need to change the locations of files like js etc) to a zip instead?
Any ideas? At the moment I'm thinking it would all need to be processed in PHP anyhow (the controller) and TWIG may not be too helpful, but that would make it more complicated.
So I worked this one out, here is the controller to output the required twig zipped:
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class DefaultController extends Controller
{
/**
* #Route("/{variableName}", name="homepage"})
*/
public function indexAction($variableName = "Default")
{
//do whatever you need to get the template correct
//send rendered TWIG to a variable
$renderedhtml = $this->render('default/index.html.twig', [
'variableName' => $variableName
])->getContent();
$zipName = "template.zip";
$main = $this->get('kernel')->getRootDir() . '/../web/workingdir/';
$vername = time(); //we use the exact time to get a unique dir name
//remove any projects older than a few minutes (5 in this case)
$dirHandle = opendir($main);
while($item = readdir($dirHandle)){
if(is_dir($main . $item) && $item != '.' && $item != '..') {
if ( ( ( $item + ( 60 * 5 ) ) < $vername ) ) {
system('/bin/rm -rf ' . escapeshellarg($main . $item));
}
}
}
//make the project dir and populate it with files (in this case just the template as index.html, you would want to copy all other files here though)
mkdir($main.$vername);
file_put_contents($main.$vername."/index.html", $renderedhtml);
//create the zip
$zip = new \ZipArchive();
$zip->open($zipName, \ZipArchive::CREATE);
$zip = $this->createZip($zip, $main.$vername);
$zip->close();
//get the zip ready to return
header('Content-Type', 'application/zip');
header('Content-disposition: attachment; filename="' . $zipName . '"');
header('Content-Length: ' . filesize($zipName));
readfile($zipName);
}
// Create a zip with zip object and root dir params (find and include sub-dirs with content)
private function createZip($zip, $source) {
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true) {
$files = new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($source), \RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {
$file = str_replace('\\', '/', $file);
if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
continue;
$file = realpath($file);
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
return $zip;
}
}
Once you get it to this stage, you will just have to add any other required files into the working dir, but I think that could be done under a different issue, this one is about getting the website into a html in a zip.
Hope this helps someone.
I want to put the allowed extensions for an image upload in the web.config for easy modification later. what I have here currently works but is hard-coded.
if (!img.RawFormat.Equals(ImageFormat.Png)
&& !img.RawFormat.Equals(ImageFormat.Gif)
&& !img.RawFormat.Equals(ImageFormat.Jpeg)
&& !img.RawFormat.Equals(ImageFormat.Bmp))
{
ViewBag.Message = "Wrong Image Type. Please use an image one with the following extenstions:<br /><b>.jpeg, .gif, .png, or .bmp</b>";
return View(location);
}
This is what I was trying, but I need to pass in an ImageFormat not a string... How do I accomplish this?
bool isAcceptedType = false;
List<string> AcceptedImageTypes = System.Configuration.ConfigurationManager.AppSettings["AcceptedImageTypes"].Split('|').ToList();
foreach (string s in AcceptedImageTypes)
{
if (img.RawFormat.Equals(s))
{
isAcceptedType = true;
}
}
if (!isAcceptedType)
{
ViewBag.Message = "Wrong Image Type. Please use an image one with the following extenstions:<br /><b>.jpeg, .gif, .png, or .bmp</b>";
return View(location);
}
I have found the answer here on this page..
How can I hide product description when the description is long in Opencart (product page) to reduce the load product page, but after clicking on the detail link then came out a full description.
In image you can see Example, Sorry for my bad english, Thanks!
Here is a link to example image example
Why not just truncate it? It will force it to be the right length for you every time!
Go to catalog/controller/product/category.php and when you see
foreach ($results as $result) {
if ($result['image']) {
$image = $this->model_tool_image->resize($result['image'], $this->config->get('config_image_product_width'), $this->config->get('config_image_product_height'));
} else {
$image = false;
}
Add this next:
function truncate($description, $tLimit="20", $break=" ", $pad="...")
{
if(strlen($string) <= $tlimit) return $string;
if(false !== ($breakpoint = strpos($string, $break, $tlimit))) {
if($breakpoint < strlen($string) - 1) {
$string = substr($string, 0, $breakpoint) . $pad;
}
}
return $description;
}
Feel free to change the variables:
$tLimit is how many letters you want to allow it.
$break is where you want it to cut off, right now it is set to cut off at the next space. You can have it interrupt words if you like by putting $break=""
$pad is what you want it to show after it cuts off the text.
If you really want no description to show at all Then I recommend still doing something similar to the original script.
function getDescriptionLength($description, $tLimit="20")
{
if(strlen($string) <= $tlimit) return $string;
else {
$description = NULL;
}
return $description;
}
