I am using laravel backpack for my site and i need to upload some images, i copy the code from their website and works fine, but i need the original name on the images, i tried some things, but is not working.
public function setImageAttribute($value)
{
$attribute_name = "image";
$disk = "uploads";
$destination_path = 'storage/services/' .date('FY').DIRECTORY_SEPARATOR;
if ($value==null) {
Storage::disk($disk)->delete($this->{$attribute_name});
// set null in the database column
$this->attributes[$attribute_name] = null;
}
if (str_starts_with($value, 'data:image'))
{
$file = $value;
$filename = $this->generateFileName($file, $destination_path);
$image = InterventionImage::make($file)->orientate();
$fullPath = $destination_path.$filename.'.'.$file->getClientOriginalExtension();
$this->attributes[$attribute_name] = $fullPath;
}
protected function generateFileName($file, $destination_path)
{
$filename = basename($file->getClientOriginalName(), '.'.$file->getClientOriginalExtension());
$filename = Str::random(20);
while (Storage::disk('uploads')->exists($destination_path.$filename.'.'.$file->getClientOriginalExtension())) {
$filename = Str::random(20);
}
return $filename;
}
why value alwys take image base64
is there any way to git image original name?
As far as I know, you won't be able to retrieve the filename, as it's always a base64 file. But maybe this work around helps you:
Image fields blade file can be found at:
\vendor\backpack\crud\src\resources\views\crud\fields\image.blade.php
You can overwrite it by making a file on the same name at:
\resources\views\vendor\backpack\crud\fields\image.blade.php
You can change anything there, maybe you can add a hidden input with the file name.
I'm trying to generate the pdf and download it using a lib based on mpdf.
But I'm trying to output-pdf and don't download it.
The script as standard displays the file in pdf on the page but I need that instead of showing on the page the file is downloaded.
Original file
public function output(string $name = null, string $dest = null)
{
$this->pdf->WriteHTML($this->render());
$this->pdf->Output($name, $dest);
}
Modified File
public function output(string $name = null, string $dest = null)
{
$pdf_data = $this->pdf->WriteHTML($this->render());
$path = '\opt\lampp\htdocs\site\public\comprovantes'.$name.'.pdf';
$this->pdf->Output('\opt\lampp\htdocs\site\public\comprovantes', $pdf_data);
}
Not Working with this modificated
WORKING With:
public function output(string $name = null, string $dest = null)
{
$content = $this->pdf->WriteHTML($this->render());
$this->pdf->Output('/opt/lampp/htdocs/site/public/comprovantes/filename.pdf', 'F');
}
I'm working with Lumen framework v5.8 (it's the same as Laravel)
I have a command for read a big XML (400Mo) and update datas in database from datas in this file, this is my code :
public function handle()
{
$reader = new XMLReader();
$reader->open(storage_path('app/mesh2019.xml'));
while ($reader->read()) {
switch ($reader->nodeType) {
case (XMLREADER::ELEMENT):
if ($reader->localName === 'DescriptorRecord') {
$node = new SimpleXMLElement($reader->readOuterXML());
$meshId = $node->DescriptorUI;
$name = (string) $node->DescriptorName->String;
$conditionId = Condition::where('mesh_id', $meshId)->first();
if ($conditionId) {
ConditionTranslation::where(['condition_id' => $conditionId->id, 'locale' => 'fr'])->update(['name' => $name]);
$this->info(memory_get_usage());
}
}
}
}
}
So, I have to find in the XML each DescriptorUI element, the value corresponds to the mesh_id attribute of my class Condition.
So, with $conditionId = Condition::where('mesh_id', $meshId)->first(); I get the Condition object.
After that, I need to update a child of Condition => ConditionTranslation. So I just get the element DescriptorName and update the name field of ConditionTranslation
At the end of the script, you can see $this->info(memory_get_usage());, and when I run the command the value increases each time until the script runs very very slowly...and never ends.
How can I optimize this script ?
Thanks !
Edit : Is there a way with Laravel for preupdate multiple object, and save just one time at the end all objects ? Like the flush() method of Symfony
There is a solution with ON DUPLICATE KEY UPDATE
public function handle()
{
$reader = new XMLReader();
$reader->open(storage_path('app/mesh2019.xml'));
$keyValues = [];
while ($reader->read()) {
switch ($reader->nodeType) {
case (XMLREADER::ELEMENT):
if ($reader->localName === 'DescriptorRecord') {
$node = new SimpleXMLElement($reader->readOuterXML());
$meshId = $node->DescriptorUI;
$name = (string) $node->DescriptorName->String;
$conditionId = Condition::where('mesh_id', $meshId)->value('id');
if ($conditionId) {
$keyValues[] = "($conditionId, '".str_replace("'","\'",$name)."')";
}
}
}
}
if (count($keyValues)) {
\DB::query('INSERT into `conditions` (id, name) VALUES '.implode(', ', $keyValues).' ON DUPLICATE KEY UPDATE name = VALUES(name)');
}
}
I want to create a slug. it should be a concatenation of title and subtitle.The following is my code and it's not working, i don't know where i went wrong?
public function setTitleAttribute($value)
{
$this->attributes['main_title'] = ucfirst($value);
$this->attributes['sub_title'] = $value;
if (! $this->exists) {
$this->attributes['slug'] = str_slug($this->attributes['main_title'].$this->attributes['sub_title']);
}
}
I need slug as a combination of main_title+sub_title
public function to_slug ($string) {
$table = array(
'Š'=>'S', 'ı'=>'i', 'ğ'=>'g', 'ü'=>'u', 'ş'=>'s', 'ö'=>'o', 'ç'=>'c', 'Ğ'=>'G', 'Ü'=>'U', 'Ş'=>'S',
'İ'=>'I', 'Ö'=>'O', 'Ç'=>'C',
'š'=>'s', 'Đ'=>'Dj', 'đ'=>'dj', 'Ž'=>'Z', 'ž'=>'z', 'Č'=>'C', 'č'=>'c', 'Ć'=>'C', 'ć'=>'c',
'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O',
'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U', 'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss',
'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c', 'è'=>'e', 'é'=>'e',
'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o',
'ô'=>'o', 'õ'=>'o', 'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'ý'=>'y', 'þ'=>'b',
'ÿ'=>'y', 'Ŕ'=>'R', 'ŕ'=>'r',
);
return preg_replace('/[^A-Za-z0-9-]+/', '-', strtr($string, $table) );
}
I'm using this code and its working for me.
It is also good for utf-8.
You can use a laravel package:
https://github.com/cviebrock/eloquent-sluggable
Or I use JavaScript when I sent the form:
https://github.com/madflow/jquery-slugify
I have replicated the exact condition like yours passing static data and its working perfectly in my machine.. try below solution.. do some dd and see whats the combination of the main_title and sub_title is resulting. Also check by removing that if condition once.
$this->attributes['main_title'] = ucfirst($value) . " ";
$this->attributes['sub_title'] = $value;
$slugToUse = $this->attributes['main_title'] . $this->attributes['sub_title'];
if (! $this->exists) {
$this->attributes['slug'] = str_slug($slugToUse);
}
}
I have tried http://docs.joomla.org/Creating_a_file_uploader_in_your_component but first it shows Error: 500 after some research I have removed code
"'.$session->getName().'" : "'.$session->getId().'",
"format" : "raw"
and error is gone. Now Image is not uploading anywhere (I have set path '/images/' folder) I am confuse in code for uploading image PART 5 where to use this code?
function storeImageFile()
{
jimport('joomla.filesystem.file');
jimport('joomla.filesystem.folder' );
$path = 'PATH_GOES_HERE'.'designs'.DS;
$folder_permissions = "0755";
$folder_permissions = octdec((int)$folder_permissions);
//create folder if not exists
if (!JFolder::exists($path)){
JFolder::create($path, $folder_permissions);
}
$file = JRequest::getVar('design_images', null, 'files',
$count = count($file['name']);
for($i=0;$i<$count;$i++)
{
//$i is the array position of the $_FILES array
if(empty($file['tmp_name'][$i]))
{
return false;
}
//Clean up filename to get rid of strange characters like spaces etc
$filename = JFile::makeSafe($file['name'][$i]);
//setting source and destination
$temporary_name = $file['tmp_name'][$i];
$filename = str_replace(' ', '_', $file['name'][$i]);
$dest = $path.$filename;
if(JFile::upload($temporary_name, $dest))
{
echo "File Upload Successful";
return true;
}
}
}
