不断出错:implode():更新数据时传递了无效的参数 [英] Keep getting error: implode(): Invalid arguments passed when updating data
问题描述
每当我尝试将某些内容更新到我的数据时，我都会不断收到此错误.上次并没有发生很多，但是在放置了新的更新功能之后，错误不断弹出，由于某种原因，即使我是在旧功能上进行更新，它也会指向我输入的新功能.
控制器:
//update for user
public function edit($id){
$object = user::find($id);
return view('edit', compact('object'));
}
public function update(Request $request, $id){
$object = user::find($id);
$object->Name = $request->input('Name');
$object->update();
return redirect('/home');
}
//update for Schools table
public function edit1($id){
$object2 = school::find($id);
return view('edit1', compact('object2'));
}
public function update1(Request $request, $id){
$object2 = school::find($id);
$test = array();
$test['School'] = implode(' , ', $request->School);
$test['SDate'] = implode(' , ', $request->SDate);
$test['EDate'] = implode(' , ', $request->EDate);
$object2->update($test);
return redirect('/home');
}
//error start here after putting this whole thing in. (I tried putting it into another separate controller but the error still continues)
public function edit2($id){
$object3 = hobby::find($id);
return view('edit2', compact('object3'));
}
public function update2(Request $request, $id){
$object3 = hobby::find($id);
$test2 = array();
$test2['computer_game'] = implode(' , ', $request->computer_game);
$test2['reading_book'] = implode(' , ', $request->reading_book);
$object3->update($test2);
return redirect('/home');
}
即使我尝试更新用户或学校数据，错误也会突出显示此部分
$test2['computer_game'] = implode(' , ', $request->computer_game);
它说
:implode():传递了无效的参数
我没有任何兴趣更新兴趣爱好数据，但是错误始终将其指向兴趣爱好内爆部分.
有可能我只能在一次爆破功能上使用一次更新吗?预先感谢
edit2.blade.php(爱好的编辑页面，如图所示，它是一个数组)
<form class="form-horizontal" method="post" action="{{ url('/user/show/'.$object3->id) }}">
{{ method_field('PUT') }}
{{ csrf_field() }}
<table class="table table-bordered table-hover" id="tab_logic">
<thead>

简单尝试以下操作:
$test2['computer_game'] = implode(' , ', (array)$request->computer_game);
如果尚未将$request->computer_game转换为数组，则会将其转换为数组.
I keep on getting this error whenever I try to update something into my data. It didn't happen a lot the last time but after putting the new update function, the error keep popping out and for some reason it points back to the new function that I had entered even though I am updating at the old function.
Controller:
//update for user
public function edit($id){
$object = user::find($id);
return view('edit', compact('object'));
}
public function update(Request $request, $id){
$object = user::find($id);
$object->Name = $request->input('Name');
$object->update();
return redirect('/home');
}
//update for Schools table
public function edit1($id){
$object2 = school::find($id);
return view('edit1', compact('object2'));
}
public function update1(Request $request, $id){
$object2 = school::find($id);
$test = array();
$test['School'] = implode(' , ', $request->School);
$test['SDate'] = implode(' , ', $request->SDate);
$test['EDate'] = implode(' , ', $request->EDate);
$object2->update($test);
return redirect('/home');
}
//error start here after putting this whole thing in. (I tried putting it into another separate controller but the error still continues)
public function edit2($id){
$object3 = hobby::find($id);
return view('edit2', compact('object3'));
}
public function update2(Request $request, $id){
$object3 = hobby::find($id);
$test2 = array();
$test2['computer_game'] = implode(' , ', $request->computer_game);
$test2['reading_book'] = implode(' , ', $request->reading_book);
$object3->update($test2);
return redirect('/home');
}
Error is highlighting this part even though when I try to update user or school data
$test2['computer_game'] = implode(' , ', $request->computer_game);
And it says
:implode(): Invalid arguments passed
I have no issue updating the hobby data but it the error keep pointing it back to the hobby implode part.
Is it possible I could only use update once on an implode function? Thanks in advance
edit2.blade.php (edit page for hobby, as shown it is an array)
<form class="form-horizontal" method="post" action="{{ url('/user/show/'.$object3->id) }}">
{{ method_field('PUT') }}
{{ csrf_field() }}
<table class="table table-bordered table-hover" id="tab_logic">
<thead>
<tr >
<th class="text-center">

<th class="text-center">

<tr id='addr0'>

</td>
<td>
<input type="text" name='computer_game[]' class="form-control"/>

<td>
<input type="text" name='reading_book[]' class="form-control"/>

<tr id='addr1'></tr>
</tbody>
</table>
<input type="submit" class="btn btn-primary" value="Save">
Just simple try the following:
$test2['computer_game'] = implode(' , ', (array)$request->computer_game);
This will convert $request->computer_game in to an array if it is not already.
