PHP 5 file upload with register_global off |
File upload part 1
In PHP 5 and above as the global variable is kept as off we can't access the uploaded file and related information by the way we handled in PHP 4. All uploaded file and its connected information will be available in an array.
$_FILES[file_up];
So to get the file size we have to use
$_FILES[file_up][size]
Note that in the form we have used the input filed name as file_up. Same way all other information can be collected.
$_FILES[file_up][type]
$_FILES[file_up][tmp_name]
$_FILES[file_up][error]
By using this way here is the code for displaying the form.
<FORM ENCTYPE="multipart/form-data" ACTION="uploadck.php" METHOD=POST>
Upload this file: <INPUT NAME="file_up" TYPE="file">
<INPUT TYPE="submit" VALUE="Send File"></FORM>
Here is the code to handle file upload.
<?
$file_upload="true";
$file_up_size=$_FILES['file_up'][size];
echo $_FILES[file_up][name];
if ($_FILES[file_up][size]>250000){$msg=$msg."Your uploaded file size is more than 250KB so please reduce the file size and then upload. Visit the help page to know how to reduce the file size.<BR>";
$file_upload="false";}
if (!($_FILES[file_up][type] =="image/jpeg" OR $_FILES[file_up][type] =="image/gif")){$msg=$msg."Your uploaded file must be of JPG or GIF. Other file types are not allowed<BR>";
$file_upload="false";}
$file_name=$_FILES[file_up][name];
$add="upload/$file_name"; // the path with the file name where the file will be stored, upload is the directory name.
if($file_upload=="true"){
if(move_uploaded_file ($_FILES[file_up][tmp_name], $add)){
// do your coding here to give a thanks message or any other thing.
}else{echo "Failed to upload file Contact Site admin to fix the problem";}
}else{echo $msg;}
?>
