Question

我在cakephp中遇到多个文件上传问题。

我尝试上传多个文件，需要在表格中插入多个条目，但我无法做到这一点。

对于Ex - 如果我从表单上传3张照片，则需要在表格中插入3行文件名。

    public function add() {
            $this->Driver->create();
            if ($this->request->is('post')) {
                    for($i=1;$i<4;$i++)
                    {
                        if(empty($this->data['Driver']['document'.$i]['name'])){
                            unset($this->request->data['Driver']['document'.$i]);
                        }

                        if(!empty($this->data['Driver']['document'.$i]['name']))
                        {
                            $file=$this->data['Driver']['document'.$i];
                            $ary_ext=array('jpg','jpeg','xls','docx'); //array of allowed extensions
                            $ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
                            if(in_array($ext, $ary_ext))
                            {
                                move_uploaded_file($file['tmp_name'], APP . 'outsidefiles' .DS. time().$file['name']); 
                                $this->request->data['Driver']['document'.$i] = time().$file['name'];
                            }
                        }

                    }

                if ($this->Driver->save($this->request->data)) 
                {
                    //echo "<pre>";print_r($this->request->data); exit();
                    $this->Session->setFlash('Your post has been saved.');
                    $this->redirect(array('action' => 'add'));
                }
                else 
                {
                    $this->Session->setFlash('Unable to add your post.');
                }
            }
        }

Plz试试这个

public function add() {
    $this->Driver->create();
    if ($this->request->is('post')) {
            for($i=1;$i<4;$i++)
            {
                if(empty($this->data['Driver']['document'][$i]['name'])){
                    unset($this->request->data['Driver']['document'.$i]);
                }

                if(!empty($this->data['Driver']['document'][$i]['name']))
                {
                    $file=$this->data['Driver']['document'][$i];
                    $ary_ext=array('jpg','jpeg','xls','docx'); //array of allowed extensions
                    $ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
                    if(in_array($ext, $ary_ext))
                    {
                        move_uploaded_file($file['tmp_name'], APP . 'outsidefiles' .DS. time().$file['name']); 
                        $this->request->data['Driver']['document'][$i] = time().$file['name'];
                    }
                }

            }

        if ($this->Driver->save($this->request->data)){
            $this->Session->setFlash('Your post has been saved.');
            $this->redirect(array('action' => 'add'));
        }else{
            $this->Session->setFlash('Unable to add your post.');
        }
    }
}

CakePHP 2 Field naming conventions

echo $this->Form->input('Modelname.0.fieldname');
echo $this->Form->input('Modelname.1.fieldname');

视图文件中的

//for($i=1; $i<4; $i++)..
echo $this->Form->input('Driver.'.$i.'.document', array('type' => 'file'));

您的控制器中的

$this->request->data['Driver'][$i]['document']['name']  // where name is uploaded document filename

使用Model::saveMany(array $data = null, array $options = array())

用于一次保存同一模型的多行的方法......

if ($this->Driver->saveMany($this->request->data))...

更新您的代码

<?php

public function add()
{
    if ($this->request->is('post')) {
        for($i=1;$i<4;$i++)
        {
            if(empty($this->request->data['Driver'][$i]['document']['name'])){
                unset($this->request->data['Driver'][$i]['document']);
            }

            if(!empty($this->request->data['Driver'][$i]['document']['name']))
            {
                $time = time(); // <-------------
                $file=$this->request->data['Driver'][$i]['document'];
                $ary_ext=array('jpg','jpeg','xls','docx'); //array of allowed extensions
                $ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
                if(in_array($ext, $ary_ext))
                {
                    move_uploaded_file($file['tmp_name'], APP . 'outsidefiles' .DS. $time.$file['name']); 
                    $this->request->data['Driver'][$i]['document'] = $time.$file['name'];
                }
            }

        }
        $this->Driver->create();
        if ($this->Driver->saveMany($this->request->data)) 
        {
            //echo "<pre>";print_r($this->request->data); exit();
            $this->Session->setFlash('Your post has been saved.');
