note 76208 added to function.move-uploaded-file

Uploading a file using PHP is not a single step function. To make this easier, I have created a function that will upload a file with just one function call. Just upload('image'); and the file is uploaded! upload() is a function that makes uploading files very easy. <?php /** * A function for easily uploading files. This function will automatically generate a new * file name so that files are not overwritten. * Arguments: $file_id- The name of the input field contianing the file. * $folder - The folder to which the file should be uploaded to - it must be writable. OPTIONAL * $types - A list of comma(,) seperated extensions that can be uploaded. If it is empty, anything goes OPTIONAL * Returns : This is somewhat complicated - this function returns an array with two values... * The first element is randomly generated filename to which the file was uploaded to. * The second element is the status - if the upload failed, it will be 'Error : Cannot upload the file 'name.txt'.' or something like that */ function upload($file_id, $folder="", $types="") { if(!$_FILES[$file_id]['name']) return array('','No file specified'); $file_title = $_FILES[$file_id]['name']; //Get file extension $ext_arr = split("\.",basename($file_title)); $ext = strtolower($ext_arr[count($ext_arr)-1]); //Get the last extension //Not really uniqe - but for all practical reasons, it is $uniqer = substr(md5(uniqid(rand(),1)),0,5); $file_name = $uniqer . '_' . $file_title;//Get Unique Name $all_types = explode(",",strtolower($types)); if($types) { if(in_array($ext,$all_types)); else { $result = "'".$_FILES[$file_id]['name']."' is not a valid file."; //Show error if any. return array('',$result); } } //Where the file must be uploaded to if($folder) $folder .= '/';//Add a '/' at the end of the folder $uploadfile = $folder . $file_name; $result = ''; //Move the file from the stored location to the new location if (!move_uploaded_file($_FILES[$file_id]['tmp_name'], $uploadfile)) { $result = "Cannot upload the file '".$_FILES[$file_id]['name']."'"; //Show error if any. if(!file_exists($folder)) { $result .= " : Folder don't exist."; } elseif(!is_writable($folder)) { $result .= " : Folder not writable."; } elseif(!is_writable($uploadfile)) { $result .= " : File not writable."; } $file_name = ''; } else { if(!$_FILES[$file_id]['size']) { //Check if the file is made @unlink($uploadfile);//Delete the Empty file $file_name = ''; $result = "Empty file found - please use a valid file."; //Show the error message } else { chmod($uploadfile,0777);//Make it universally writable. } } return array($file_name,$result); } ?> Documentation : http://www.bin-co.com/php/scripts/upload_function/ ---- Server IP: 203.199.69.133 Probable Submitter: 61.17.222.185 ---- Manual Page -- http://www.php.net/manual/en/function.move-uploaded-file.php Edit -- https://master.php.net/note/edit/76208 Del: integrated -- https://master.php.net/note/delete/76208/integrated Del: useless -- https://master.php.net/note/delete/76208/useless Del: bad code -- https://master.php.net/note/delete/76208/bad+code Del: spam -- https://master.php.net/note/delete/76208/spam Del: non-english -- https://master.php.net/note/delete/76208/non-english Del: in docs -- https://master.php.net/note/delete/76208/in+docs Del: other reasons-- https://master.php.net/note/delete/76208 Reject -- https://master.php.net/note/reject/76208 Search -- https://master.php.net/manage/user-notes.php
