Hello,

I'm trying to provide the ability to upload more than one file in the configuration of one of my custom blocks. I got the basics, but everytime I click on upload button, I get this:

*Notice*: Undefined index: uec_core_socials_block_image in * uec_core_socials_block_image_validate() **Notice*: Undefined index: files_fieldset in *uec_core_socials_block_image_validate()

*I don't know why I'm getting this because the index is there and works for other blocks I have created that way.* *I'm also following the ajax_examples module in the examples module.

*Below is the snippet I'm working with:

function uec_core_block_configure($delta = '') { $form = array(); switch($delta) {* *case 'uec_core_socials': $form['#tree'] = TRUE; $form['files_fieldset'] = array( '#type' => 'fieldset', '#title' => t('Upload social icons'), // Set up the wrapper so that AJAX will be able to replace the fieldset. '#prefix' => '<div id="names-fieldset-wrapper">', '#suffix' => '</div>', ); // Build the fieldset with the proper number of files. We'll use // $form_state['num_files'] to determine the number of managed_file fields to build. if (empty($form_state['num_files'])) { $form_state['num_files'] = 1; } // provide ability to add more files for ($i = 0; $i < $form_state['num_files']; $i++) {

$form['files_fieldset']['uec_core_socials_block_image'][$i] = array( '#type' => 'managed_file', '#title' => t('Image'), '#description' => t('Upload an image to represent social icons, allowed extensions: jpg, jpeg, png, gif'), '#default_value' => variable_get('uec_core_socials_block_image', ''), '#element_validate' => array('uec_core_socials_block_image_validate'), '#upload_location' => 'public://' //If this is not set, the file will be uploaded to temporary dir. Then use file_move to move it to drupal default file system location ); } $form['files_fieldset']['add_file'] = array( '#type' => 'submit', '#value' => t('Add one more'), '#submit' => array('uec_core_socials_add_more_add_one'), // See the examples in ajax_example.module for more details on the // properties of #ajax. '#ajax' => array( 'callback' => 'uec_core_socials_add_more_callback', 'wrapper' => 'names-fieldset-wrapper', ), ); break; } return $form; }

/**

• Callback for both ajax-enabled buttons.
• Selects and returns the fieldset with the names in it.

*/ function uec_core_socials_add_more_callback($form, $form_state) { return $form['files_fieldset']; }

/**

• Submit handler for the "add-one-more" button.
• Increments the max counter and causes a rebuild.

*/ function uec_core_socials_add_more_add_one($form, &$form_state) { $form_state['num_files']++; $form_state['rebuild'] = TRUE; }

function uec_core_socials_block_image_validate($form, &$form_state) { variable_set('uec_core_socials_block_image', $form_state['values']['files_fieldset']['uec_core_socials_block_image']); //variable_set('uec_core_socials_block_image', $form_state['values']['uec_core_socials_block_image']); }

I'll like to know what I'm doing wrong.

I was able to fix it with this:

variable_set('uec_core_socials_block_image', $form_state['values']['settings']['files_fieldset']['uec_core_socials_block_image']);
