I am trying to get a multiple upload library working for my Codeigniter based website. I have it working almost but I have a slight problem if I upload more than one image, the file extentions get screwed up; for example, if I upload three JPEGS, I get this in my uploads folder, <pre><code>image1.jpg image2.jpg.jpg image3.jpg.jpg.jpg </code></pre> I cannot see what is causing it, this is the library in question and I am pretty sure that it is in there that the problem is, <pre><code><?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); /** * This library assumes that you have already loaded the default CI Upload Library seperately * * Functions is based upon CI_Upload, Feel free to modify this * library to function as an extension to CI_Upload * * Library modified by: Alvin Mites * http://www.mitesdesign.com * */ class Multi_upload { function Multi_upload () { // $CI =& get_instance(); } /** * Perform multiple file uploads * Based upon JQuery Multiple Upload Class * see http://www.fyneworks.com/jquery/multiple-file-upload/ */ function go_upload($field = 'userfile') { $CI =& get_instance(); // Is $_FILES[$field] set? If not, no reason to continue. if ( ! isset($_FILES[$field]['name'][0])) { $CI->upload->set_error('upload_no_file_selected'); return FALSE; } else { $num_files = count($_FILES[$field]['name']) -1; $file_list = array(); $error_hold = array(); $error_upload = FALSE; } // Is the upload path valid? if ( ! $CI->upload->validate_upload_path()) { // errors will already be set by validate_upload_path() so just return FALSE return FALSE; } for ($i=0; $i < $num_files; $i++) { // $fname = $_FILES[$field]['name'][$i]; // echo "$fname\n\n \n\n"; $error_hold[$i] = FALSE; // Was the file able to be uploaded? If not, determine the reason why. if ( ! is_uploaded_file($_FILES[$field]['tmp_name'][$i])) { $error = ( ! isset($_FILES[$field]['error'][$i])) ? 4 : $_FILES[$field]['error'][$i]; switch($error) { case 1: // UPLOAD_ERR_INI_SIZE $error_hold[$i] = 'upload_file_exceeds_limit'; break; case 2: // UPLOAD_ERR_FORM_SIZE $error_hold[$i] = 'upload_file_exceeds_form_limit'; break; case 3: // UPLOAD_ERR_PARTIAL $error_hold[$i] = 'upload_file_partial'; break; case 4: // UPLOAD_ERR_NO_FILE $error_hold[$i] = 'upload_no_file_selected'; break; case 6: // UPLOAD_ERR_NO_TMP_DIR $error_hold[$i] = 'upload_no_temp_directory'; break; case 7: // UPLOAD_ERR_CANT_WRITE $error_hold[$i] = 'upload_unable_to_write_file'; break; case 8: // UPLOAD_ERR_EXTENSION $error_hold[$i] = 'upload_stopped_by_extension'; break; default : $error_hold[$i] = 'upload_no_file_selected'; break; } return FALSE; } // Set the uploaded data as class variables $CI->upload->file_temp = $_FILES[$field]['tmp_name'][$i]; $CI->upload->file_name = $CI->upload->_prep_filename($_FILES[$field]['name'][$i]); $CI->upload->file_size = $_FILES[$field]['size'][$i]; $CI->upload->file_type = preg_replace("/^(.+?);.*$/", "\\1", $_FILES[$field]['type'][$i]); $CI->upload->file_type = strtolower($CI->upload->file_type); $CI->upload->file_ext = $CI->upload->get_extension($_FILES[$field]['name'][$i]); // Convert the file size to kilobytes if ($CI->upload->file_size > 0) { $CI->upload->file_size = round($CI->upload->file_size/1024, 2); } // Is the file type allowed to be uploaded? if ( ! $CI->upload->is_allowed_filetype()) { $error_hold[$i] = 'upload_invalid_filetype'; } // Is the file size within the allowed maximum? if ( ! $CI->upload->is_allowed_filesize()) { $error_hold[$i] = 'upload_invalid_filesize'; } // Are the image dimensions within the allowed size? // Note: This can fail if the server has an open_basdir restriction. if ( ! $CI->upload->is_allowed_dimensions()) { $error_hold[$i] = 'upload_invalid_dimensions'; } // Sanitize the file name for security $CI->upload->file_name = $CI->upload->clean_file_name($CI->upload->file_name); // Remove white spaces in the name if ($CI->upload->remove_spaces == TRUE) { $CI->upload->file_name = preg_replace("/\s+/", "_", $CI->upload->file_name); } /* * Validate the file name * This function appends an number onto the end of * the file if one with the same name already exists. * If it returns false there was a problem. */ $CI->upload->orig_name = $CI->upload->file_name; if ($CI->upload->overwrite == FALSE) { $CI->upload->file_name = $CI->upload->set_filename($CI->upload->upload_path, $CI->upload->file_name); if ($CI->upload->file_name === FALSE) { $error_hold[$i] = TRUE; } } /* * Move the file to the final destination * To deal with different server configurations * we'll attempt to use copy() first.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
