Programmatically uploading files and overwrite them (not use filename_0.txt)

Posted by carlovdb on November 6, 2012 at 1:33pm

Hello,

I have created a new module based on example 10. Now, this works all fine, but I just want to overwrite the file, not renaming it with filename_[digit].extension

I thought this was possible with FILE_EXISTS_REPLACE, but this doesn't do the job..

This is the code that I use.

<?php
function form_example_tutorial_10_validate($form, &$form_state) {
  $file = file_save_upload('file', array(
    'file_validate_extensions' => array('csv'), // Validate extensions.
    FILE_EXISTS_REPLACE
  ));
  // If the file passed validation:
  if ($file) {
    // Move the file, into the Drupal file system
    if ($file = file_move($file, 'public://')) {
      // Save the file for use in the submit handler.
      $form_state['storage']['file'] = $file;
    }
    else {
      form_set_error('file', t('Failed to write the uploaded file the site\'s file folder.'));
    }
  }
  else {
    form_set_error('file', t('No file was uploaded.'));
  }
}
?>

Can someone help me?

If what I asks is not possible, is it possible to first do a check if the file exists and then delete the older file and then save the new one with the correct filename?

FILE_EXISTS_REPLACE is the

FILE_EXISTS_REPLACE is the correct value to use, you're just using it in the wrong place. Change the file_move call:

<?php
if ($file = file_move($file, 'public://', FILE_EXISTS_REPLACE)) {
?>

If you don't add the FILE_EXISTS_REPLACE to the file_move, this can't work :)

<?php
function form_example_tutorial_10_validate($form, &$form_state) {
  $file = file_save_upload('file', array(
    'file_validate_extensions' => array('csv'), // Validate extensions.
    'public://',FILE_EXISTS_REPLACE
  ));
  // If the file passed validation:
  if ($file) {
    // Move the file, into the Drupal file system
    if ($file = file_move($file, 'public://', FILE_EXISTS_REPLACE)) {
      // Save the file for use in the submit handler.
      $form_state['storage']['file'] = $file;
    }
    else {
      form_set_error('file', t('Failed to write the uploaded file the site\'s file folder.'));
    }
  }
  else {
    form_set_error('file', t('No file was uploaded.'));
  }
}
?>
