witchy478 Posted August 14, 2012 Share Posted August 14, 2012 Hi I was busy doing a tutorial called How to Upload Files with CodeIgniter and AJAX, I did everything like it said but it's not uploading or saving the content. this is the upload controller <?php class Upload extends CI_Controller { public function __construct() { parent::__construct(); $this->load->model('files_model'); $this->load->database(); $this->load->helper('url'); } public function index() { $this->load->view('upload'); } public function upload_file() { $status = ""; $msg = ""; $file_element_name = 'userfile'; if (empty($_POST['title'])) { $status = "error"; $msg = "Please enter a title"; } if ($status != "error") { $config['upload_path'] = './files/'; $config['allowed_types'] = 'gif|jpg|png|doc|txt'; $config['max_size'] = 1024 * 8; $config['encrypt_name'] = TRUE; $this->load->library('upload', $config); if (!$this->upload->do_upload($file_element_name)) { $status = 'error'; $msg = $this->upload->display_errors('', ''); } else { $data = $this->upload->data(); $file_id = $this->files_model->insert_file($data['file_name'], $_POST['title']); if($file_id) { $status = "success"; $msg = "File successfully uploaded"; } else { unlink($data['full_path']); $status = "error"; $msg = "Something went wrong when saving the file, please try again."; } } @unlink($_FILES[$file_element_name]); } echo json_encode(array('status' => $status, 'msg' => $msg)); } public function files() { $files = $this->files_model->get_files(); $this->load->view('files', array('files' => $files)); } public function delete_file($file_id) { if ($this->files_model->delete_file($file_id)) { $status = 'success'; $msg = 'File successfully deleted'; } else { $status = 'error'; $msg = 'Something went wrong when deleteing the file, please try again'; } echo json_encode(array('status' => $status, 'msg' => $msg)); } } This is my files_model <?php class Files_Model extends CI_Model { public function insert_file($filename, $title) { $data = array( 'filename' => $filename, 'title' => $title ); $this->db->insert('files', $data); return $this->db->insert_id(); } public function delete_file($file_id) { $file = $this->get_file($file_id); if (!$this->db->where('id', $file_id)->delete('files')) { return FALSE; } unlink('./files/' . $file->filename); return TRUE; } public function get_files() { return $this->db->select() ->from('files') ->get() ->result(); } public function get_file($file_id) { return $this->db->select() ->from('files') ->where('id', $file_id) ->get() ->row(); } } This is my upload view <!doctype html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> <script src="<?php echo base_url()?>js/site.js"></script> <script src="<?php echo base_url()?>js/ajaxfileupload.js"></script> <link href="<?php echo base_url()?>css/style.css" rel="stylesheet" /> </head> <body> <h1>Upload File</h1> <p class="error"></p> <form method="post" action="<?php echo site_url('/upload/upload')?>" id="upload_file"> <label for="title">Title</label> <br /> <input type="text" name="title" id="title" value="" /> <br /> <label for="userfile">File</label> <br /> <input type="file" name="userfile" id="userfile" size="20" /> <br /> <input type="submit" name="submit" id="submit" /> </form> <h2>Files</h2> <div id="files"></div> </body> </html> This is my files view <?php if (isset($files) && count($files)) { ?> <ul> <?php foreach ($files as $file) { ?> <li class="image_wrap"> <a href="#" class="delete_file_link" data-file_id="<?php echo $file->id?>">Delete</a> <strong><?php echo $file->title?></strong> <br /> <?php echo $file->filename?> </li> <?php } ?> </ul> </form> <?php } else { ?> <p>No Files Uploaded</p> <?php } ?> Link to comment https://forums.phpfreaks.com/topic/267079-uploadinginserting-images-problem/ Share on other sites More sharing options...
witchy478 Posted August 14, 2012 Author Share Posted August 14, 2012 I forgot to add my js files this is site.js $(function() { $('#upload_file').submit(function(e) { e.preventDefault(); $.ajaxFileUpload({ url :'./upload/upload_file/', secureuri :false, fileElementId :'userfile', dataType : 'json', data : { 'title' : $('#title').val() }, success : function (data, status) { if(data.status != 'error') { $('#files').html('<p>Reloading files...</p>'); refresh_files(); $('#title').val(''); } alert(data.msg); } }); return false; }); refresh_files(); $('.delete_file_link').live('click', function(e) { e.preventDefault(); if (confirm('Are you sure you want to delete this file?')) { var link = $(this); $.ajax({ url : './upload/delete_file/' + link.data('file_id'), dataType : 'json', success : function (data) { if (data.status == "success") { link.parents('li').fadeOut('fast', function() { $(this).remove(); if ($('#files li').length == 0) { $('#files').html('<p>No Files Uploaded</p>'); } }); } else { alert(data.msg); } } }); } }); }); function refresh_files() { $.get('./upload/files/') .success(function (data){ $('#files').html(data); }); } and this is ajaxfileupload.js jQuery.extend({ createUploadIframe: function(id, uri) { //create frame var frameId = 'jUploadFrame' + id; var iframeHtml = '<iframe id="' + frameId + '" name="' + frameId + '" style="position:absolute; top:-9999px; left:-9999px"'; if(window.ActiveXObject) { if(typeof uri== 'boolean'){ iframeHtml += ' src="' + 'javascript:false' + '"'; } else if(typeof uri== 'string'){ iframeHtml += ' src="' + uri + '"'; } } iframeHtml += ' />'; jQuery(iframeHtml).appendTo(document.body); return jQuery('#' + frameId).get(0); }, createUploadForm: function(id, fileElementId, data) { //create form var formId = 'jUploadForm' + id; var fileId = 'jUploadFile' + id; var form = jQuery('<form action="" method="POST" name="' + formId + '" id="' + formId + '" enctype="multipart/form-data"></form>'); if(data) { for(var i in data) { jQuery('<input type="hidden" name="' + i + '" value="' + data[i] + '" />').appendTo(form); } } var oldElement = jQuery('#' + fileElementId); var newElement = jQuery(oldElement).clone(); jQuery(oldElement).attr('id', fileId); jQuery(oldElement).before(newElement); jQuery(oldElement).appendTo(form); //set attributes jQuery(form).css('position', 'absolute'); jQuery(form).css('top', '-1200px'); jQuery(form).css('left', '-1200px'); jQuery(form).appendTo('body'); return form; }, ajaxFileUpload: function(s) { // TODO introduce global settings, allowing the client to modify them for all requests, not only timeout s = jQuery.extend({}, jQuery.ajaxSettings, s); var id = new Date().getTime() var form = jQuery.createUploadForm(id, s.fileElementId, (typeof(s.data)=='undefined'?false:s.data)); var io = jQuery.createUploadIframe(id, s.secureuri); var frameId = 'jUploadFrame' + id; var formId = 'jUploadForm' + id; // Watch for a new set of requests if ( s.global && ! jQuery.active++ ) { jQuery.event.trigger( "ajaxStart" ); } var requestDone = false; // Create the request object var xml = {} if ( s.global ) jQuery.event.trigger("ajaxSend", [xml, s]); // Wait for a response to come back var uploadCallback = function(isTimeout) { var io = document.getElementById(frameId); try { if(io.contentWindow) { xml.responseText = io.contentWindow.document.body?io.contentWindow.document.body.innerHTML:null; xml.responseXML = io.contentWindow.document.XMLDocument?io.contentWindow.document.XMLDocument:io.contentWindow.document; }else if(io.contentDocument) { xml.responseText = io.contentDocument.document.body?io.contentDocument.document.body.innerHTML:null; xml.responseXML = io.contentDocument.document.XMLDocument?io.contentDocument.document.XMLDocument:io.contentDocument.document; } }catch(e) { //jQuery.handleError(s, xml, null, e); console.log('ERROR', s, xml, null, e); } if ( xml || isTimeout == "timeout") { requestDone = true; var status; try { status = isTimeout != "timeout" ?
