'-'.$request->mobile_no.'.'.$file->getclientoriginalextension();               echo $name."<br>";              //tried didn't work             //$request->imagepath = $name;              $file->move(public_path().'/images/collectors', $name);              $request->merge(array('imagepath' => $name));              echo $request->imagepath."<br>";      }

please help

i believe merge() correct method, merge provided array existing array in parameterbag.

however, you're accessing input variables incorrectly. try using $request->input('parameter_name') instead...

therefore, code should this:

if ($request->hasfile('imagepath')) {     $file = input::file('imagepath');     $name = "{$request->input('name')}-{$request->input('mobile_no')}.{$file->getclientoriginalextension()}";      $file->move(public_path('/images/collectors'), $name);     $request->merge(['imagepath' => $name]);      echo $request->input('imagepath')."<br>"; } 

note: can pass path public_path() , concatenate you.
