fwrite($handle, $graph);
the problem is that i have more than one document and in my json file shows only the last document
please can any one helps
Before line:
foreach ($documents as $document)
you should add:
$arraydoc = array();
and then change line:
$arraydoc= array('name' =>$document->nomdoc,'image'=>$imagedo,'group'=>3);
into:
$arraydoc[] = array('name' =>$document->nomdoc,'image'=>$imagedo,'group'=>3);

I'm having a problem with a soap response in laravel...
I'm calling the soap in the controller like this :
public function users()
{
$user = Auth::user();
$users = User::all();
// webservice X3
$soapclient = new SoapClient($this->WSDL, $this->params);
// method x3
$wsname = 'ZWSUSR01';
$xml='<?xml version="1.0" encoding="utf-8"?>';
$xml.='<PARAM>';
$xml.='</PARAM>';
$result = $soapclient->run($this->CContext, $wsname, $xml);
$status = $result->status;
$i=0;
if ($status == 1) {
$xml = simplexml_load_string($result->resultXml);
foreach ($xml->TAB->LIN as $line) {
$x3users[$i]= array();
foreach ($line->FLD as $name) {
$x3users[$i]["".$name['NAME'].""] = (string)$name;
}
$i++;
}
$x3users= json_encode($x3users, JSON_UNESCAPED_UNICODE );
} else {
$message = $result->resultXml;
$vars = array(
'xwebservice' => $wsname,
'xident' => $id,
'xmessage' => $message
);
$this->erroRotinas($vars);
$xml='';
}
return view('configs.users', compact(['users', 'x3users']));
}
When i call in the view the response using {{ $x3users }} it gives me the result in json and it looks fine [{...},{...},{...}]
But if I do #foreach($x3users as $x3user) it returns Invalid argument supplied for foreach() (View:
What can it be?
I am doing a project with Laravel 7. I have to read a csv file and through a controller passing the data in json format to a view.
Unfortunately I don't know how to do that.
These are my controller methods:
public function index($source)
{
$source = strtolower($source);
switch ($source) {
case "csv":
$file_csv = base_path('transactions.csv');
$transactions = $this->csvToJson($file_csv);
dd(gettype($transactions));
return view('transactions', ['source' => $source, 'transactions' => $transactions]);
break;
case "db":
$transactions = Transaction::all();
dd(gettype($transactions));
return view('transactions', ['source' => $source, 'transactions' => $transactions]);
break;
default:
abort(400, 'Bad sintax error.');
}
}
function csvToJson($filename = '', $delimiter = ',')
{
if (!file_exists($filename) || !is_readable($filename)) {
return false;
}
$header = null;
$data = array();
if (($handle = fopen($filename, 'r')) !== false)
{
while (($row = fgetcsv($handle, 1000, $delimiter)) !== false)
{
if (!$header)
$header = $row;
else
$data[] = array_combine($header, $row);
}
fclose($handle);
}
return $data;
}
As you can see, under the two cases I put a dd with a gettype function inside. In the first case I receive uncorrectly the response array, in the second one I receive correctly the response object.
The converted csv file should have this format:
[{"id":1,"code":"T_218_ljydmgebx","amount":"8617.19","user_id":375,"created_at":"2020-01-19T16:08:59.000000Z","updated_at":"2020-01-19T16:08:59.000000Z"},
{"id":2,"code":"T_335_wmhrbjxld","amount":"6502.72","user_id":1847,"created_at":"2020-01-19T16:08:59.000000Z","updated_at":"2020-01-19T16:08:59.000000Z"}]
Do you know how to convert the array transactions into a json object in the first case?
I don't know if there is any build-in solution on Laravel, but it can be done by PHP.
I didn't test my code. So it might not work, or contain some typos, but I'm sure it will give you some directions.
$cols = ["id","code","amount","user_id","created_at","updated_at"];
$csv = file('folder/name.csv');
$output = [];
foreach ($csv as $line_index => $line) {
if ($line_index > 0) { // I assume the the first line contains the column names.
$newLine = [];
$values = explode(',', $line);
foreach ($values as $col_index => $value) {
$newLine[$cols[$col_index]] = $value;
}
$output[] = $newLine;
}
}
$json_output = json_encode($output);
You can just do this :
$csv= file_get_contents($file);
$array = array_map('str_getcsv', explode(PHP_EOL, $csv));
$json json_encode($array);
If you want to return json object
return $json;
If you want to create a .json file
// Pure PHP
$file = fopen('results.json', 'w');
fwrite($file, $json);
fclose($file);
// Laravel using Storage
Storage::disk('local')->put('public/result.json', $json);
I hope this helps somone.
I have an email marketing application where I made bulk importers. So here is their CSV TO JSON code.
function convert_csv_to_json($csv_data){
// CSV to JSON process 1
$context = array(
'http'=>array(
'follow_location' => false,
'max_redirects' => 1000000
)
);
$context = stream_context_create($context);
if (($handle = fopen($csv_data, "r", false, $context)) !== FALSE) {
$csvs = [];
while(! feof($handle)) {
$csvs[] = fgetcsv($handle);
}
$datas = [];
$column_names = [];
foreach ($csvs[0] as $single_csv) {
$column_names[] = $single_csv;
}
foreach ($csvs as $key => $csv) {
if ($key === 0) {
continue;
}
foreach ($column_names as $column_key => $column_name) {
$datas[$key-1][$column_name] = $csv[$column_key];
}
}
return $json = json_encode($datas);
}
// OR
// CSV to JSON process 1
$cols = ['id',
'owner_id',
'name',
'email',
'country_code',
'phone',
'favourites',
'blocked',
'trashed',
'is_subscribed',
'deleted_at',
'created_at',
'updated_at.'];
$csv = file($csv_data);
$output = [];
foreach ($csv as $line_index => $line) {
if ($line_index > 0) { // I assume the the first line contains the column names.
$newLine = [];
$values = explode(',', $line);
foreach ($values as $col_index => $value) {
$newLine[$cols[$col_index]] = $value;
}
$output[] = $newLine;
}
}
return $json_output = json_encode($output);

I am creating Laravel 7 project and I want to add/browse images into/from MySQL database.
The images column names are icon_lg and icon_sm
This is my create function in the Controller I tried it in two ways as I saw in some tutorials:
public function create(Request $request)
{
$object = $this->objectModel::create([
'name' => $request->name,
'icon_sm' => $request->icon_sm
]);
if($request->hasFile('icon_lg')) {
$images = explode(',', $request->hasFile('icon_lg'));
foreach($images as $image)
$filename = rand().'.'.$image->getClientOriginalExtension();
$filePath = public_path("images");
$image->move($filePath, $filename);
return Image::create([
'icon_lg' => $filename,
//'item_id' => $created->id,
]);
}
if ($request->save == 'browse')
return redirect()->route("{$this->objectName}");
elseif ($request->save == 'edit')
return redirect()->route("{$this->objectName}.edit", ['id' => $object]);
elseif ($request->save == 'add')
return redirect()->route("{$this->objectName}.add");
else
return redirect($request->previous_url);
}
It does nothing with icon_lg it inserts null value to it.
And it deals with icon_sm as String.
i think you must set the hasfile validation inside foreach loop like
$images = explode(',', $request->hasFile('icon_lg'));
foreach($images as $image)
if($request->hasFile('icon_lg')) {
$filename = rand().'.'.$image->getClientOriginalExtension();
$filePath = public_path("images");
$image->move($filePath, $filename);
return Image::create([
'icon_lg' => $filename,
//'item_id' => $created->id,
]);
}
just test it without validation first
it should work
I have this function in Laravel 5.1
public function calcolaKilometri()
{
$partenza = Input::get('partenza');
$destinazione = Input::get('destinazione');
$distanceMatrix = new DistanceMatrix(new Client(), new GuzzleMessageFactory());
$response = $distanceMatrix->process(new DistanceMatrixRequest(
[$partenza],
[$destinazione]
));
foreach ($response->getRows() as $row) {
foreach ($row->getElements() as $element) {
$distance = $element->getDistance();
$text = $distance->text;
$value = $distance->value;
$data = ['text' => $text, 'value' => $value];
return \Response::json($data);
}
}
}
need to return to Ajax JSON data but this function return plain HTML response, because we are in a forech loop. How i can do the trick?
I'm not sure I fully understand what you're saying but I assume you want to return all of the data found when looping through your result set in a single JSON response.
Try something like this:
// Your previous code...
// Initialise a $data array here, that we're going to fill with data
$data = [];
foreach ($response->getRows() as $row) {
foreach ($row->getElements() as $element) {
$distance = $element->getDistance();
$text = $distance->text;
$value = $distance->value;
// Append the new set of data to your array
$data[] = ['text' => $text, 'value' => $value];
}
}
// Return the data as JSON only when we've filled it with everything
return response()->json($data);
Try This...
$json = json_encode($data);
return \Response::json($json);
Solved using sessions. If someone have the same issue:
public function calcolaKilometri()
{
$partenza = Input::get('partenza');
$destinazione = Input::get('destinazione');
$distanceMatrix = new DistanceMatrix(new Client(), new GuzzleMessageFactory());
$response = $distanceMatrix->process(new DistanceMatrixRequest(
[$partenza],
[$destinazione]
));
foreach ($response->getRows() as $row) {
foreach ($row->getElements() as $element) {
$text = $element->getDistance()->getText();
$value = $element->getDistance()->getValue();
\Session::put('testo', $text);
\Session::put('valore', $value);
}
}
// Return the data as JSON only when we've filled it with everything
$testo = \Session::get('testo');
$valore = \Session::get('valore');
$result = ['text' => $testo, 'value' => $valore];
return \Response::json($result);
}
i would like to output dynamic generated html content instead of the translatable message but i can't make it work:
function custom_logo_module_block_view($delta = '') {
// don't worry about switch($delta) logic
// perform some operations and then display some generated html
// (maybe use the template(...) function)
// works fine but i'd like to print html
$block['content'] = t('No content available.');
return $block;
}
how can i print out generated html into a block?
i can't find any solutions or code examples. i think i might be pointing towards the wrong direction so best practice suggestions are welcome.
function custom_logo_module_block_view($delta = '') {
$block = array();
if ($delta == 'example') {
$block = array(
'subject' => t('Active users list'),
'content' => example_block_content()
);
}
return $block;
}
function example_block_content() {
// Query for active users from database
$users = db_select('users', 'u')
->fields('u', array('uid', 'name'))
->condition('u.status', 1)
->execute()
->fetchAll();
// Prepare items for item list
$items = array();
foreach ($users as $user) {
$items[] = l($user->name, "user/{$user->uid}");
}
$output = t('No active users available.');
if (!empty($items)) {
$output = theme('item_list', array('items' => $items));
}
return $output;
}
Update regarding your comments...
As far as I understand by some result you mean generated data from database. In this case you can try something like this:
function example_block_content() {
// Query for active users from database
$users = db_select('users', 'u')
->fields('u', array('uid', 'name'))
->condition('u.status', 1)
->execute()
->fetchAll();
$output = '';
foreach ($users as $user) {
$output.= '<div>'. $user->name .'</div>';
}
$output = "<div>Hello World". $output ."</div>";
return $output;
}
This will give you the following output:
<div>Hello World
<div>admin</div>
<div>ndrizza</div>
<div>Vlad Stratulat</div>
...
</div>
Or you can try:
function custom_logo_module_block_view($delta = '') {
$block = array();
if ($delta == 'example') {
$block = array(
'subject' => t('Active users list'),
// this will return "Hello World + some result" text inside <div>
'content' => "<div>Hello World + some result</div>"
);
}
return $block;
}
Both of this ways are working but they are not the right ways. The right way to generate content is in my first answer. Read more about theming in Drupal.
