note 58621 added to features.file-upload

I had problems when uploading files using Internet Explorer and Firefox. I checked for extension and mime-type to make sure it was a jpeg-file my users uploaded. Firefox did it well, only Internet Explorer failed to accept the file saying it wasn't the correct mime-type. After some testing, I discovered that Firefox reads the mime-type of a Jpeg-image as: image/jpeg While Internet Explorer reads it as: image/pjpeg I hope this helps somebody to avoid an evening debugging. To contribute to php.net, I enclosed my secure upload script for Jpeg files: <?php function storefile($var, $location, $filename=NULL, $maxfilesize=NULL) { $ok = false; // Check file $mime = $_FILES[$var]["type"]; if($mime=="image/jpeg" || $mime=="image/pjpeg") { // Mime type is correct // Check extension $name = $_FILES[$var]["name"]; $array = explode(".", $name); $nr = count($array); $ext = $array[$nr-1]; if($ext=="jpg" || $ext=="jpeg") { $ok = true; } } if(isset($maxfilesize)) { if($_FILES[$var]["size"] > $maxfilesize) { $ok = false; } } if($ok==true) { $tempname = $_FILES[$var]['tmp_name']; if(isset($filename)) { $uploadpath = $location.$filename; } else { $uploadpath = $location.$_FILES[$var]['name']; } if(is_uploaded_file($_FILES[$var]['tmp_name'])) { while(move_uploaded_file($tempname, $uploadpath)) { // Wait for the script to finish its upload } } return true; } else { return false; } } ?> You can use this script as follow: <? if(isset($_FILES['name'])) { if(storefile("name", $_SERVER['DOCUMENT_ROOT']."test/img")) { echo("Upload succeeded!"); } else { echo("Upload failed..."); } } ?> The last 2 parameters 'filename' and 'maxfilesize' are optional. Offcourse, you can change this script with other mime types and extensions to fit your needs. ---- Manual Page -- http://www.php.net/manual/en/features.file-upload.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58621 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58621&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58621&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58621&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58621&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58621&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58621&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58621&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58621&report=yes Search -- http://master.php.net/manage/user-notes.php
