如何使用Laravel中的Summernote更新图像的文章

Question

我已经在Laravel实施了Summernote，并在预期的图像上上传了一篇文章。在更新文章时，它可以在文章没有图像时起作用。但是对于带有图像的文章，它会引发和错误，未定义的数组键。

这是浏览器上有错误的突出显示行，list（$ type，$ data）= Explode（';'，$ data）;。该行是loop中的第二行（update（）方法。

我的商店方法

 public function store(Request $request)
    {
        $this->validate($request, [
            'title' => 'required',
            'body' => 'required'
        ]);

        $content = $request->body;
        $dom = new \DomDocument();
        $dom->loadHtml($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
        $imageFile = $dom->getElementsByTagName('img');

        foreach ($imageFile as $item => $image) {
            $data = $image->getAttribute('src');
            list($type, $data) = explode(';', $data);
            list(, $data)      = explode(',', $data);
            $imgeData = base64_decode($data);
            $image_name = "/upload/" . time() . $item . '.png';
            $path = public_path() . $image_name;
            file_put_contents($path, $imgeData);

            $image->removeAttribute('src');
            $image->setAttribute('src', $image_name);
        }

        $content = $dom->saveHTML();
        $post = Post::create([
            'title' => $request->title,
            'body' => $content
        ]);

        // dd($post->toArray());
        return redirect(route('posts.index'));
    }

我的更新方法

 public function update(Request $request, Post $post)
    {

        $this->validate($request, [
            'title' => 'required',
            'body' => 'required'
        ]);

        $content = $request->body;
        libxml_use_internal_errors(true);
        $dom = new \DomDocument();
        $dom->loadHtml($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD | libxml_use_internal_errors(true));
        $imageFile = $dom->getElementsByTagName('img');

        foreach ($imageFile as $item => $image) {
            $data = $image->getAttribute('src');
            list($type, $data) = explode(';', $data);
            list(, $data)      = explode(',', $data);
            $imgeData = base64_decode($data);
            $image_name = "/upload/" . time() . $item . '.png';
            $path = public_path() . $image_name;
            file_put_contents($path, $imgeData);

            $image->removeAttribute('src');
            $image->setAttribute('src', $image_name);
        }

        $content = $dom->saveHTML();
        $post->title = $request->title;
        $post->body = $content;
        $post->save();
        return redirect()->back();
    }

更新文章时，您不必转换已经转换的图像（从blob到链接到文件）

public function update(Request $request, Post $post)
{

    $this->validate($request, [
        'title' => 'required',
        'body' => 'required'
    ]);

    $content = $request->body;
    libxml_use_internal_errors(true);
    $dom = new \DomDocument();
    $dom->loadHtml($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD | libxml_use_internal_errors(true));
    $imageFile = $dom->getElementsByTagName('img');

    foreach ($imageFile as $item => $image) {
        $data = $image->getAttribute('src');
        if (strpos($data, ';') === false) {
            continue;
        }
        list($type, $data) = explode(';', $data);
        list(, $data)      = explode(',', $data);
        $imgeData = base64_decode($data);
        $image_name = "/upload/" . time() . $item . '.png';
        $path = public_path() . $image_name;
        file_put_contents($path, $imgeData);

        $image->removeAttribute('src');
        $image->setAttribute('src', $image_name);
    }

    $content = $dom->saveHTML();
    $post->title = $request->title;
    $post->body = $content;
    $post->save();
    return redirect()->back();
}
