Question

我设置此表单的目的是在将详细信息添加到时；标题，描述和情感文本字段，然后按Submit，此数据将以xml格式存储在php文件中。

我正在努力设置控制器，以便在提交表单时它实际上存储了该数据。当我将其存储在数据库中时，下面将提供的示例可以正常工作，但是现在我想将其存储为xml。

项目负责人

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Orchestra\Parser\Xml\Facade as XmlParser;

interface OutputType
{
public function generate();
}

//project class has been imported
use App\Project;

class ProjectsController extends Controller
{
public function index()
{
    //because the class has been imported we can reference it like this rather than '\App\Project::all();'
    $projects = Project::all();



//passing the JSON to the view

    return view ('projects.index', ['projects'=> $projects]); //can also use 'compact('projects') instead of the ['projects'=> $projects]
 }



//new method called create

public function create()
{

    return view ('projects.create');

}

//new method called store


public function store()
 {

  if (isset($_POST['submit'])) {
    $xmlType = new XMLType();
    $xmlType->createParent('programme', ['id' => 1])
            ->addElement('name', $_POST['name'], ['type' => 'string'])
            ->addElement('description', $_POST['description'])
            ->addElement('mood', $_POST['mood'])
            ->groupParentAndElements()
            ->createParent('others', ['id' => 2, 'attr' => 'ex'])
            ->addElement('example', 'A value here')
            ->groupParentAndElements();

    //whenever you wish to output
    $xmlType->generate();
 }



return view('projects.upload');
}


//changed this from upload to show
public function upload()
{


return view('projects.upload');
}

//changed this from upload to show
public function show()
{


return view ('projects.upload', compact('user'));
}

public function slider()
{


return view ('projects.upload', compact('user'));
}


}

Answer 1

我会考虑使用SQLite将数据存储为第二个数据库连接

https://www.sqlite.org

或者，您需要使用诸如SimpleXML之类的方法来获取文件的内容，添加或修改内容，然后将其保存回文件中。

http://php.net/manual/en/book.simplexml.php

这一切都需要使用您的store方法，并且不允许您使用Projects模型

希望这会有所帮助

XMLFile类

        interface OutputType
        {
            public function generate();
        }

您希望在哪里使用XML类

            //import the interface above

        class XMLType implements OutputType
        {
            protected $xml;

            protected $parentElement;
            protected $elementGroup;


            protected $parentList = [];
            protected $elementList = [];

            public function __construct()
            {
                $this->xml= new \DOMDocument('1.0', 'ISO-8859-15');
            }

            public function createParent($type, $attributes = [])
            {
                $this->parentElement = $this->xml->createElement($type);
                $this->addAttributes($this->parentElement, $attributes);

                return $this;
            }

            private function addAttributes(&$element, $attributes)
            {
                if (sizeof($attributes) > 0) {
                    foreach($attributes as $type => $value) {
                        $element->setAttribute($type, $value);
                    }
                }
            }

            public function addElement($type, $element, $attributes = [])
            {
                 $this->elementGroup  = $this->xml->createElement($type, $element);
                 $this->addAttributes($this->elementGroup, $attributes);
                 $this->elementList[] = $this->elementGroup;
                 return $this;
            }

            /**
             *  We wish to trigger this every time you want to ad d a new parent to
             *  hold new elements! So the program knows to close
             *  the previous one before starting a new and mesh all into one single
             *  element, which we do not want to!
            **/
            public function groupParentAndElements()
            {
                foreach($this->elementList as $prevElements) {
                    $this->parentElement->appendChild($prevElements);
                }

                $this->parentList[] = $this->parentElement;
                $this->elementList = [];

                return $this;
            }

            public function generate()
            {
                //Uses filled parentList where each parent contains its child elements to generate the XML
                foreach ($this->parentList as $prevParent) {
                    $this->xml->appendChild($prevParent);    
                }

                //here I am saving and printing but you can change to suit your needs.
                //It is at this point it is ready to generate the XML
                print $this->xml->saveXML(); 
            } 

        }

输出

            if (isset($_POST['submit'])) {
                $xmlType = new XMLType();
                $xmlType->createParent('programme', ['id' => 1])
                        ->addElement('name', $_POST['name'], ['type' => 'string'])
                        ->addElement('description', $_POST['description'])
                        ->addElement('mood', $_POST['mood'])
                        ->groupParentAndElements()
                        ->createParent('others', ['id' => 2, 'attr' => 'ex'])
                        ->addElement('example', 'A value here')
                        ->groupParentAndElements();

                //whenever you wish to output
                $xmlType->generate();
            }

您可以始终在类中添加额外的元素，例如注释，类型等，这将取决于您的XML需求。只需遵循结构，甚至进一步：）

working code example

将XML内容存储到文件中

            <programme id="1">
                <name type="string">
                    //your post name
                </name>
                <description>
                    //your post description
                </description>
                <mood>
                    //your post mood
                </mood>
            </programme>
            <others id="2" attr="ex">
               <example>
                   A value here
               </example>
            </others>

在构建XML内容之后，在您的控制器上

interface FileCreationContract
{
    public function create($content);
}


class XMLFile implements FileCreationContract
{

    const REGEX_EXTENTION_LOOKOUT = '/\.[^.]+$/';
    const EXTENTION = '.xml';

    protected $path;
    protected $filename;

    public function __construct ($filename, $path = '')
    {
        $this->filename = $filename;
        $this->parseFilename();

        if (empty($this->path)) {
            $this->path = realpath(__DIR__);
        }
    }

    /**
     * If programmer mistakes and adds extention, removes it to make sure the wrong extention was not added;
     */
    private function parseFilename()
    {
        if ( strpos($this->filename, self::EXTENTION) === FALSE ) {
            $this->filename = preg_replace(self::REGEX_EXTENTION_LOOKOUT, '', $this->filename) . self::EXTENTION;
        }

        if (empty($this->filename)) {
            $this->filename = 'default-name'.self::EXTENTION;
        }
    }

    /**
     * @return mixed
     */
    public function getPath ()
    {
        return $this->path;
    }

    /**
     * @param mixed $path
     *
     * @return XMLFile
     */
    public function setPath ($path)
    {
        $this->path = $path;
        return $this;
    }

    /**
     * @return mixed
     */
    public function getFilename ()
    {
        return $this->filename;
    }

    /**
     * @param mixed $filename
     *
     * @return XMLFile
     */
    public function setFilename ($filename)
    {
        $this->filename = $filename;
        $this->parseFilename();
        return $this;
    }

    public function create ($content)
    {
        $file = fopen($this->path.$this->filename, 'w') or die("Unable too open file!"); //I recommend throwing an exception here!
        fwrite($file, $content);
        fclose($file);
    }

}

注意：在... $xmlFile = new XMLFile('database.php', 'path/to/your/public/folder/'); $xmlFile->create($xmlType->generate()); ...类的print方法中将return替换为generate()

该新类将确保您的文件名遵循预期的XMLType格式进行保存。在调用.xml之前，您始终可以覆盖路径以在构造器级别保存文件，或调用->setPath('new/path/');来替换它。
