PHP code to upload multiple files with database - php

Question

I have issue with multiple file upload in cakephp.
I try to upload multiple files and need to insert multiple entries in table, but I am unable to do this.
For Ex - if I upload 3 photos from form then need to be inserted 3 rows in table with their file name.
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.');
}
}
}
add.ctp
<h1>Add Post</h1><?php
echo $this->Form->create('Driver', array('url' => array('action' => 'add'), 'enctype' => 'multipart/form-data'));
echo $this->Form->input('address',array('div' => false, 'class' => 'form-control user-name'));
for($i=1; $i<4; $i++)
{
?>
<div id="attachment<?php echo $i;?>" <?php if($i !=1) echo "style='display:none;'";?> >
<div>
<?php echo $this->Form->input('document'.$i,array('type'=>'file','label' => false,'div' => false));?>
</div>
<div id="attachmentlink<?php echo $i;?>" <?php if($i==3) echo "style='display:none;'";?>>Add Another Attachment</div>
</div>
<?php } ?>
<?php
echo $this->Form->end('Save');
?>

Plz try this
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 $this->Form->input('Modelname.1.fieldname');
in your view file
//for($i=1; $i<4; $i++)..
echo $this->Form->input('Driver.'.$i.'.document', array('type' => 'file'));
in your controller like
$this->request->data['Driver'][$i]['document']['name'] // where name is uploaded document filename
Use Model::saveMany(array $data = null, array $options = array())
Method used to save multiple rows of the same model at once...
if ($this->Driver->saveMany($this->request->data))...
UPDATE your code
<?php
public function add()
{
if ($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.');
$this->redirect(array('action' => 'index'));
}
else
{
$this->Session->setFlash('Unable to add your post.');
}
}
}
