Upload a file to a selectable folder

[neo71]

I need to upload a file to a folder based on one of three possible categories

$folder1= “uploads/categoryA/”;
$folder2 = “uploads/categoryB/”;
$folder3 = “uploads/categoryC/”;

with a select I set the categories to the variable

then I upload

if (isset($_POST[‘btn-upload’])) {
if (isset($_FILES[‘file’]))
{ move_uploaded_file($file_loc,$folder1.$final_file); }

this works but I would like the file to be uploaded via $category in the corresponding $folder

How does the User tell your code which "category" a file belongs to? 

Presumably, that would be another Form field, passed at the same time as the uploaded file itself. 
[Validate and then] Use that value to construct the target path for the file and pass that value to move_uploaded_file(). 

// pseudo-code
if ( isset( $_POST[ 'btn-upload' ] ) ) {
   if ( validatePostArguments( $_POST ) ) {
      $targetFile  = buildTargetPath( $_POST[ 'category' ], $_FILES[ 'file' ] ); 
      move_uploaded_file( $file_loc, $targetFile ); 
   }
}

Thak u!. users choose a category by a select:

 

 

<fieldset>
Sellct category:<br>
<select name="siti" onchange="this.form.nome_mulino.disabled=(this.options[this.selectedIndex].value=='MOLINI')?false:true" >
<option value="MOLINI" selected="selected">ACQUA, FORZA MOTRICE. I MOLINI, RISORSA DI IERI E DI DOMANI</option>
<option value="VITA">LA VITA NEL FIUME</option>
<option value="FIUMI">I NOSTRI FIUMI VISTI DALL’ALTO</option>
		
Nome mulino<input type="text" name="nome_mulino" disabled="disabled" />
</select>
</fieldset>

$category = $_POST[‘siti’];

$category = $_POST[‘siti’];

 

Or, perhaps better (i.e. safer) ... 

switch( $_POST[ 'siti' ] ) 
{
   case: 'FIUMI' : 
   case: 'MOLINI' : 
   case: 'VITA' : 
      $category = $_POST[ 'siti' ] ; 
      break; 
   default: 
      throw new \Exception( 'Invalid category!' ); 
}

Why? 
Just because you send the User an HTML SELECT list to use does not guarantee that the value you receive comes from that list!

This should help.

$category = $_POST['category'];

    $folder1 = "uploads/categoryA/";
    $folder2 = "uploads/categoryB/";
    $folder3 = "uploads/categoryC/";

     switch ($category) {
        case 'categoryA':
            $uploadFolder = $folder1;
            break;
        case 'categoryB':
            $uploadFolder = $folder2;
            break;
        case 'categoryC':
            $uploadFolder = $folder3;
            break;
        default:
            die("Invalid category");
    }

    // it check if the folder exists, if not, it create it
    if (!file_exists($uploadFolder)) {
        mkdir($uploadFolder, 0777, true);
    }

    $uploadedFile = $_FILES['file']['tmp_name'];
    $destination = $uploadFolder . $_FILES['file']['name'];

    if (move_uploaded_file($uploadedFile, $destination)) {
        echo "File successfully uploaded to $uploadFolder";
    } else {
        echo "Error uploading file";
    }
