I want to convert all null with empty string I have used array_walk_recursive but I haven't got what I want please help me to figure it out what I have done wrong here.
protected function setData($key, $value)
{
$this->data[$key] = $value;
array_walk_recursive($this->data, function (&$item, $key) {
$item = null === $item ? '' : $item;
});
return $this->data;
}
well, that's just a lamp mistake in eloquent we always get result in eloquent object and here I'm passing eloquent object inside array_walk_recursive so before passing I need to convert into array from eloquent object using ->toArray() method in laravel like this.
inside User Controller
$this->setData("friendList", $loadFriends->friends->toArray());
then array_walk_recursive will work.
protected function setData($key, $value)
{
array_walk_recursive($value, function (&$item, $key) {
$item = null === $item ? '' : $item;
});
$this->data[$key] = $value;
return $this->data;
}
Your array_walk_recursive() method should be modified as follows.
array_walk_recursive($input, function($i) use (&$output) {
$output[] = is_null($i)? '': $i;
});
var_dump($output);
$output contains the result you wanted. You can return it or do whatever you want to do with it.
Note: you can instead use array_walk() if $input not an associative array.
class InputCleanup
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
$input = $request->input();
array_walk_recursive($input, function(&$value) {
if (is_string($value)) {
$value = StringHelper::trimNull($value);
}
});
$request->replace($input);
return $next($request);
}
}
$item = !is_null($item) ? $item : '';
