我在发布数据以更新已成功更新的所有内容时遇到 302 重定向问题，除了我收到 302 并且我的页面被重定向的图像。
这是我的表单 Blade 代码:
{!! Form::model($post, ['method' => 'PATCH','route' => ['posts.update', $post->id],'data-parsley-validate' => '','class' => 'form-horizontal','files'=>true,'name'=>'updateabout']) !!}

和我的 Controller :
public function update(Request $request, $id)
{
// Validate the data
$postdata = Post::find($id);
//print_r($post);
if ($request->input('slug') == $postdata->slug) {
//echo 'slug match';
//exit();
$this->validate($request, [
'title' => 'required|max:255',
'category_id' => 'required|integer',
'long_description' => 'required',
]);
} else {
//echo 'new slug matching';
//exit();
$this->validate($request, [
'title' => 'required|max:255',
'slug' => 'required|alpha_dash|min:5|max:255|unique:posts,slug',
'category_id' => 'required|integer',
'long_description' => 'required',
]);
}
if ($request->hasFile('imagemain')) {
//echo 'request has old file to unlink ';
// exit();
//unlink($request->get('image'));
// Get filename with the extension
$filenameWithExt = $request->file('imagemain')->getClientOriginalName();
// Get just filename
$filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
// Get just ext
$extension = $request->file('imagemain')->getClientOriginalExtension();
$fileNameToStore = $filename . '_' . time() . '.' . $extension;
// Upload Image
$path = $request->file('imagemain')->move('public/blogsimages', $fileNameToStore);
// Filename to store
echo $fileNameToStore = $path;
} else {
$fileNameToStore = $request->input('imageold');
// exit();
}
// Save the data to the database
$post = Post::find($id);
$post->title = $request->input('title');
$post->slug = $request->input('slug');
$post->category_id = $request->input('category_id');
$post->description = $request->input('description');
$post->short_description = $request->input('short_description');
$post->date = $request->input('date');
$post->image = $fileNameToStore;
$post->meta_title = $request->input('meta_title');
$post->meta_keywords = $request->input('meta_keywords');
$post->authorname = $request->input('authorname');
$post->save();
if (isset($request->tags)) {
$post->tags()->sync($request->tags);
} else {
$post->tags()->sync([]);
}
// set flash data with success message
Session::flash('success', 'This post was successfully saved.');
// redirect with flash data to posts.show
return redirect()->route('posts.show', $post->id);
}
当我发布数据时，除了显示 302 的图像和表格外，所有内容都根据要求进行了更新，这里是屏幕截图:
我的路线是:Route::resource('posts', 'PostController');
最佳答案
我认为验证脚本有错误 请尝试代码
public function update(Request $request, $id)
{
// Validate the data
$postdata = Post::find($id);
//WITHOUT VALIDATION
if ($request->hasFile('imagemain')) {
//echo 'request has old file to unlink ';
// exit();
//unlink($request->get('image'));
// Get filename with the extension
$filenameWithExt = $request->file('imagemain')->getClientOriginalName();
// Get just filename
$filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
// Get just ext
$extension = $request->file('imagemain')->getClientOriginalExtension();
$fileNameToStore = $filename . '_' . time() . '.' . $extension;
// Upload Image
$path = $request->file('imagemain')->move('public/blogsimages', $fileNameToStore);
// Filename to store
echo $fileNameToStore = $path;
} else {
$fileNameToStore = $request->input('imageold');
// exit();
}
// Save the data to the database
$post = Post::find($id);
$post->title = $request->input('title');
$post->slug = $request->input('slug');
$post->category_id = $request->input('category_id');
$post->description = $request->input('description');
$post->short_description = $request->input('short_description');
$post->date = $request->input('date');
$post->image = $fileNameToStore;
$post->meta_title = $request->input('meta_title');
$post->meta_keywords = $request->input('meta_keywords');
$post->authorname = $request->input('authorname');
$post->save();
if (isset($request->tags)) {
$post->tags()->sync($request->tags);
} else {
$post->tags()->sync([]);
}
// set flash data with success message
Session::flash('success', 'This post was successfully saved.');
// redirect with flash data to posts.show
return redirect()->route('posts.show', $post->id);
}
这将解决您的问题。
