Hi,

How we can add the file upload field in Drupal 7 custom form.Once uploaded and submitted, the file is to be saved in /sites/all/default/file.

Thanks

Can I recommend looking at the examples module. If you look at the last tutorial on forms, it shows how to upload a file, validate, and save.

form_example_tutorial_10

Hi I tried the code in form_example_tutorial_10

the file was uploaded in the "files" folder inside default.But this error is showing up:

Notice: Undefined property: stdClass::$uri in file_save() (line 575 of includes\file.inc).

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '' for key 'uri': INSERT INTO {file_managed} (filesize, status, timestamp) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2); Array ( [:db_insert_placeholder_0] => 0 [:db_insert_placeholder_1] => 1 [:db_insert_placeholder_2] => 1334752869 ) in drupal_write_record() (line 6776 of includes\common.inc).

Can you please advice?

Can you show your code?

From the error message it seems you are putting the uri into file_save(), but you should be using the file object instead.

Here it is:

under hook_menu:

$form['file'] = array(
'#type' => 'file',
'#title' => t('Image'),
'#description' => t('Upload a file, allowed extensions: jpg, jpeg, png, gif'),
);

under hook_validation:

$file = file_save_upload('file', array(
'file_validate_is_image' => array(),
'file_validate_extensions' => array('png gif jpg jpeg'),
));
if ($file) {
if ($file = file_move($file, 'public://')) {
$form_state['values']['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.'));
}
}

under hook_submit:

$file=$form_state['values']['file'];
unset($form_state['values']['file']);
$file->status = FILE_STATUS_PERMANENT;
file_save($file);
drupal_set_message(t('The form has been submitted and the image has been saved, filename: @filename.', array('@filename' => $file->filename)));

Works fine for me.

 

<?php
function test_menu() {
  $items = array();
 
  $items['test'] = array(
    'title' => 'test',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('testform'),
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );

  return $items;
}

function testform($form, &$form_state) {
  $form = array();
  $form['file'] = array(
        '#type' => 'file',
        '#title' => t('Image'),
        '#description' => t('Upload a file, allowed extensions: jpg, jpeg, png, gif'),
  );
  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('Submit'),
  );

  return $form;
}

function testform_validate($form, &$form_state) {
  $file = file_save_upload('file', array(
      'file_validate_is_image' => array(),
      'file_validate_extensions' => array('png gif jpg jpeg'),
  ));
  if ($file) {
    if ($file = file_move($file, 'public://')) {
      $form_state['values']['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.'));
  }
}

function testform_submit($form, &$form_state) {
  $file=$form_state['values']['file'];
  unset($form_state['values']['file']);
  $file->status = FILE_STATUS_PERMANENT;
  file_save($file);
  drupal_set_message(t('The form has been submitted and the image has been saved, filename: @filename.', array('@filename' => $file->filename)));
}
