[thelist] How do I delete uploaded files in PHP?

[Nan Harbison]

Anthony,

I tried this ftp method as a stupid wild stab at something that might work,
I found it on a website explaining how to delete files. Resumes are uploaded
using PHP file upload functions, mainly using this function, written by
Marcos Thiago <fabismt at yahoo.com.br>:

  function moveFileToDestination(){

    if(is_uploaded_file($this->tmp_name) && $this->dst_dir){
      if($this->checkUploadConditions()){
        $dst_file_name = ($this->randon_name) ? $this->generateFileName() :
$this->fixFileName($this->name);
        $full_destination_path = $this->dst_dir."/".$dst_file_name;
        if(file_exists($full_destination_path) && !$this->replace) {
          $this->error_type = 7;
        } else {
          if(@move_uploaded_file($this->tmp_name,$full_destination_path)){
            @chmod ($this->dst_dir."/".$dst_file_name,$this->file_perm);
            $this->error_type = 0; 
          } else {
            $this->error_type = 5; 
          }
        }
      }
    } else {
      $this->error_type = 6; 
    }

    if($this->error_type != 0){
      $this->fail_files_track[$this->succeed_track_index]["file_name"]
= $this->name;
      $this->fail_files_track[$this->succeed_track_index]["new_file_name"]
= $dst_file_name;
 
$this->fail_files_track[$this->succeed_track_index]["destination_directory"]
= $this->dst_dir;
      $this->fail_files_track[$this->succeed_track_index]["field_name"]
= $this->fld_name;
      $this->fail_files_track[$this->succeed_track_index]["file_size"]
= $this->size;
      $this->fail_files_track[$this->succeed_track_index]["file_type"]
= $this->type;
      $this->fail_files_track[$this->succeed_track_index]["error_type"]
= $this->error_type;
      $this->fail_files_track[$this->succeed_track_index++]["msg"]
= $this->msg[$this->error_type];
      return FALSE;
    } else {
      $this->succeed_files_track[$this->fail_track_index]["file_name"]
= $this->name;
      $this->succeed_files_track[$this->fail_track_index]["new_file_name"]
= $dst_file_name;
 
$this->succeed_files_track[$this->fail_track_index]["destination_directory"]
= $this->dst_dir;
      $this->succeed_files_track[$this->fail_track_index]["field_name"]
= $this->fld_name;
      $this->succeed_files_track[$this->fail_track_index]["file_size"]
= $this->size;
      $this->succeed_files_track[$this->fail_track_index]["file_type"]
= $this->type;
      $this->succeed_files_track[$this->fail_track_index]["error_type"]
= $this->error_type;
      $this->succeed_files_track[$this->fail_track_index++]["msg"]
= $this->msg[$this->error_type];
      return TRUE;
    }
  }

The unlink function didn't work for me. I will reread the php.net page you
sent me. 
Thanks
Nan

How are your resumes being posted to the site?? Are you using the built-in
PHP File Upload functions?

http://us.php.net/manual/en/features.file-upload.php

I'm curious as to why you are using FTP at all. Are you receiving them via
the web service and the transporting them via FTP to a specific location?
Are the files local to the web server?

If you login manually with your FTP credentials can you see the files you
expect? Can you delete them manually?

If the files are local to the web sever, make sure that the web server has
the proper permissions on the files. You should be using this PHP function
on files that are local:

http://us.php.net/manual/en/function.unlink.php
