php - Call to a member function fill() on null -


i want update keeping following information:

$radicado = \app\radicado::find($id);         $radicado->fill($request->all());         $radicado->codigoradicado = $request['codigoradicado'];         $radicado->dependencia_iddependencia = $request['dependencia_iddependencia'];         $radicado->serie_idserie = $request['serie_idserie'];         $radicado->subserie_idsubserie = $request['subserie_idsubserie'];         $radicado->save();         if($request->ajax())     {         return response()->json(['message' => 'actualizado correctamente']);     }      return redirect('/radicado');

and run following ajax

var token = document.getelementbyid('token').value;     $.ajax({         async: true,         headers: {'x-csrf-token': token},         url: $(formid).attr('action'),         type: $(formid).attr('method'),         data: $(formid).serialize(),         datatype: 'html',         success: function(result){             $(formid)[0].reset();             alert(result);             document.getelementbyid("preview").style.display = "none";         },         error: function(){             alert('no se ha actualizado el documento.');         }     });

but when error store: call member function fill() on null

the first 2 lines shown this:

$radicado = \app\radicado::find($id); $radicado->fill($request->all());

the error because find() statement did not find record $id. since did not find record, returns null. since returns null, $radicado null, , cannot call methods on null value.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
