php - File upload form does not work with large files -
i have pretty standard upload form. few text inputs, file upload input, recaptcha, , submit button.
under normal use, can upload small file fine. form data redirected page in action attribute, , while bunch of things done in php , sql handles uploads.
however, when trying upload 40 mb file, not work. @ first, thought captcha, since gave me errors failing type in correct words. after disabling captcha, found variables defined $_post['input'] not being passed through. php errors such as:
notice: undefined index: name in /var/www/upload.php on line 18 where line 18 $name=$_post['name'];
i 1 of these every input in form.
this telling me post not being set because form not working when sending large files, question simply...why? , of course, what's solution?
edit: relevant code:
submit form:
<form action="/upload.php" method="post" enctype="multipart/form-data"> <ul> <li> <input class="text" type="text" name="name"> </li> <li> <input class="text" type="email" name="email" placeholder="<?php echo $content['submitformemailplaceholder'];?>"> </li> <li> <input type="file" name="file"> <input class="text" type="text" name="url" placeholder="http://"> </li> <li> <textarea class="text" name="notes" rows="5"></textarea> </li> <li> <?php require_once($_server['document_root'].'/resources/recaptchalib.php'); $publickey = "key"; echo recaptcha_get_html($publickey); ?> </li> <li> <input type="submit"> </li> </ul> </form> upload code:
<?php date_default_timezone_set('utc'); //echo $_files['file']['error']; require_once($_server['document_root'].'/resources/recaptchalib.php'); $privatekey="key"; $resp=recaptcha_check_answer($privatekey,$_server["remote_addr"],$_post["recaptcha_challenge_field"],$_post["recaptcha_response_field"]); if(!$resp->is_valid){ echo "<h1>".$content['uploaderror']."</h1>".$content['uploadcaptcha']."<br><br>".$content['uploadreturn']; }else{ $name=$_post['name']; $email=$_post['email']; if(empty($name)){ echo "<h1>".$content['uploaderror']."</h1>".$content['uploadname']."<br><br>".$content['uploadreturn']; }elseif(empty($email)){ echo "<h1>".$content['uploaderror']."</h1>".$content['uploademail']."<br><br>".$content['uploadreturn']; }else{ $url=$_post['url']; $notes=$_post['notes']; $timedate=date('ymdhis'); $dbhandle=new pdo("mysql:host=localhost;dbname=upload;","user","password",array(pdo::attr_emulate_prepares => false)); $dbhandle->setattribute(pdo::attr_errmode, pdo::errmode_exception); $query=$dbhandle->prepare("insert `data` (approved,name,email,fileid,url,notes,timedate,viewcount) values(?,?,?,?,?,?,?,?)"); $types=array( 'jpg','jpeg','gif','png', 'mp3','wma','wav','ogg','aac','flac', 'avi','wmv','mov','ogg','webm','mpg','mpeg','mp4' ); $filechk=(isset($_files['file']) && !empty($_files['file']['name'])); $urlchk=(isset($url) && !empty($url)); if(!$filechk ^ $urlchk){ echo "<h1>".$content['uploaderror']."</h1>".$content['uploadfileurl']."<br><br>".$content['uploadreturn']; }elseif($filechk){ $filesize=(75*1024*1024); $up_path=$_server['document_root'].'/resources/uploads/'; $filename=$timedate.$_files['file']['name']; $ex=explode(".",$filename); $ext=strtolower(end($ex)); if(file_exists($up_path.$filename)) { $filename=$timedate.'duplicate.'.$ext; } if(!in_array($ext,$types)){ echo "<h1>".$content['uploaderror']."</h1>".$content['uploadfiletype']."<br><br>".$content['uploadreturn']; }elseif(filesize($_files['file']['tmp_name'])>$filesize){ echo "<h1>".$content['uploaderror']."</h1>".$content['uploadfilesize'].($filesize/1024/1024)." mb<br><br>".$content['uploadreturn']; }elseif(!is_writable($up_path)){ echo "<h1>".$content['uploaderror']."</h1>".$content['uploadwriteerror']."<br><br>".$content['uploadreturn']; }elseif(move_uploaded_file($_files['file']['tmp_name'],$up_path.$filename)){ $fileid=$filename; $url=null; $query->execute(array('n',$name,$email,$fileid,$url,$notes,$timedate,'0')); echo "<h1>".$content['uploadsuccess']."</h1>".$content['uploadhomepage']; }else{ echo "<h1>".$content['uploadunknownerror']."</h1>".$content['uploadreturn']; } }else{ $fileid=null; $query->execute(array('n',$name,$email,$fileid,$url,$notes,$timedate,'0')); echo "<h1>".$content['uploadsuccess']."</h1>".$content['uploadhomepage']; } } } ?>
try , increase upload_max_filesize , post_max_size in php.ini file. set them both 50m sure.
you should restart apache after changing this, too. depends on setup, replace pathtoapache path apache on server;
sudo /etc/pathtoapache/apache2 restart
