多个文件到文件夹中

Question

Hello I have a view file and controller, what makes multiple inputs where I can upload files in to folder, but its uploading only one file in to folder. I know what is problem, but I dont know how to fix this or how to do this.

My Controller:

public function uploadFile() {
        $filename = '';
            if ($this->request->is('post')) { // checks for the post values
                $uploadData = $this->data['files'];
                //print_r($this->data['files']); die;
                if ( $uploadData['size'] == 0 || $uploadData['error'] !== 0) { // checks for the errors and size of the uploaded file
                    echo "Failide maht kokku ei tohi olla üle 5MB";
                    return false;
                }
                $filename = basename($uploadData['name']); // gets the base name of the uploaded file
                $uploadFolder = WWW_ROOT. 'files';  // path where the uploaded file has to be saved
                $filename = $filename; // adding time stamp for the uploaded image for uniqueness
                $uploadPath =  $uploadFolder . DS . $filename;
                if( !file_exists($uploadFolder) ){
                    mkdir($uploadFolder); // creates folder if  not found
                }
                if (!move_uploaded_file($uploadData['tmp_name'], $uploadPath)) {
                    return false;
                } 
                echo "Sa sisestasid faili(d): $filename";

            }           
    }

My View file:

<?php
    echo $this->Form->create('uploadFile', array( 'type' => 'file'));
?>

    <div class="input_fields_wrap">

        <label for="uploadFilefiles"></label>
        <input type="file" name="data[files]" id="uploadFilefiles">

    </div>

<button type="button" class="add_field_button">+</button> <br><br>

    <form name="frm1" method="post" onsubmit="return greeting()">
        <input type="submit" value="Submit">
    </form>

<?php
echo $this->Html->script('addFile');

And this script what Im using in View :

$(document).ready(function() {
    var max_fields      = 3;
    var wrapper         = $(".input_fields_wrap");
    var add_button      = $(".add_field_button");

    var x = 1;
    $(add_button).click(function(e){
        e.preventDefault();
        if(x < max_fields){
            x++;
            $(wrapper).append("<div><input type='file' name='data[files]' id='uploadFilefiles'/><a href='#' class='remove_field'>Kustuta</a></div>");
        }
     });

      $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
            e.preventDefault(); $(this).parent('div').remove(); x--;
        })
});

I think that, the problem is in input names. If Im doing more inputs, then the inputs names are same, and thanks to this its uploading only one file in to webroot/files folder, but I want these all.

Can anybody help me or give me some tips. Thanks !

Answer 1

Here is someone with almost exactly the same issue as you have: Create multiple Upload File dynamically

Try doing the same. I haven't programmed PHP for quite some time, but I guess you should replace data[files] to just data[], so it creates a new array item for each field. Now you are giving each field the same name.

Then you can loop over them in your controller by using:

foreach($_FILES['data'] as $file){
  //do stuff with $file
}

EDIT 2: As you are saying, you want to upload the files (not to a db). So I guess this should work:

public function uploadFile() {
        $filename = '';
            if ($this->request->is('post')) { // checks for the post values
                $uploadData = $this->data;
                foreach($uploadData as $file){

                if ( $file['size'] == 0 || $file['error'] !== 0) { // checks for the errors and size of the uploaded file
                    echo "Failide maht kokku ei tohi olla üle 5MB";
                    return false;
                }
                $filename = basename($file['name']); // gets the base name of the uploaded file
                $uploadFolder = WWW_ROOT. 'files';  // path where the uploaded file has to be saved
                $filename = $filename; // adding time stamp for the uploaded image for uniqueness
                $uploadPath =  $uploadFolder . DS . $filename;
                if( !file_exists($uploadFolder) ){
                    mkdir($uploadFolder); // creates folder if  not found
                }
                if (!move_uploaded_file($file['tmp_name'], $file)) {
                    return false;
                } 
                echo "Sa sisestasid faili(d): $filename";

            }       
         }    
    }
