If you want to upload in a custom folder you can use the following function. Add the function in functions.php
function upload_user_file( $file = array(),$path ) {
if(!empty($file))
{
$upload_dir=$path;
$uploaded=move_uploaded_file($file['tmp_name'], $upload_dir.$file['name']);
if($uploaded)
{
echo "uploaded successfully ";
}else
{
echo "some error in upload " ;print_r($file['error']);
}
}
}
Make a form in your template file like this:
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" name="upload">
</form>
Call the upload function in template file like before get_header() function:
if(isset($_POST['upload']))
{
if( ! empty( $_FILES ) )
{
$file=$_FILES['file']; // file array
$upload_dir=wp_upload_dir();
$path=$upload_dir['basedir'].'/myuploads/'; //upload dir.
if(!is_dir($path)) { mkdir($path); }
$attachment_id = upload_user_file( $file ,$path);
}
}
