Displaying information to user after each loop

tcsnguy08

I am still trying to create my upload page and currently have a loop running to analyze uploaded files for correct format size ,etc. My problem is I want a way to display after each file in the loop has been analyzed something like this.

We are currently analyzing your upload file.........Then display DONE when it skips to the next file. The problem lies however that when I upload the files, the status message isn't displayed until all the loops are done, after the php has analyzed all the files. It doesn't really make sense for me to include this status message after the entire set has been analyzed, since the user will already know the analyzing has been done. I have my upload code here, can anyone give me a suggestion as to output the status message after each file in the loop has been analyzed. Thanks in advance for any help.

$limit_size="1000000";
$numtracks = $_SESSION['numtracks'];
$r = 1;
if (4 >=$numtracks){
$q = $numtracks;
}
if (4 < $numtracks){
$q = 4;
}
while ($r <= $q){
$songname[$r] = $_FILES['upload']['name'][$r];
$check_imagename[$r] = explode(".", $songname[$r]);
$verify_imagename[$r] = count($check_imagename[$r]);
$extimagename[$r] = @strrchr($songname[$r], ".");
$tmpName[$r] = basename($_FILES['upload']['tmp_name'][$r]);
$file_size[$r] = $_FILES['upload']['size'][$r];
$tmpdelete = $workdir . "/" . $tmpName[$r];
if ($file_size[$r] == ""){
$errorempty = true;
}
if ($errorempty[$r] !==true){
if ($verify_imagename[$r] > "2"){
$errorsongname = true;
}
}
if ($errorsongname !==true and $errorempty !==true){
if ($extimagename[$r] !== ".jpg"){
$errorsong = true;
}
}
if ($errorsongname !==true and $errorsong !==true and $errorempty !==true){
if($file_size[$r] > $limit_size) {
$errorsize =true;
}
}
echo "We are currently analyzing the upload"." ".$_FILES['upload']['name'][$r] . " ";
flush();
$r++;
echo "Done<br><br>";
flush();
}

here is the form that submits it:

<form action=\"".$_SERVER['PHP_SELF']."\" method=\"POST\" input enctype=\"multipart/form-data\">
<table width=\"600\" bgcolor=\"#EEEEEE\">
";
if (!isset($_SESSION['uploadcount'])){
$k = 1;
if (4 >= $numtracks){
$i = $numtracks;
}
if (4 < $numtracks){
$i = 4;
}
while ($k <= $i){
echo"<tr><td align=\"left\" valign=\"top\">".$k."</td><td align=\"center\">".$_SESSION['title'][$k]."<input name=\"upload[$k]\" size=\"40\" type=\"file\"><br><br></td></tr>";
$k++;
}
echo"<tr><td></td><td align=\"center\"><input type=\"image\" src=\"images/submitbutton.jpg\" name=\"uploadsongs1\"></td></tr></table></form>";

It outputs everything fine, but all four loops at the end, not after each successive loop like I would like. Thanks Again

You will need an ajax / javascript kinda upload for that to work. PHP will run on the server, and has no interaction with the user untill the script is done.

Actually, you'll need a lot more than just Javascript for that. The problem is that your browser doesn't receive data from the server until it has finished transmitting all data for the POST operation. In other words, all files will be uploaded before the server sends back a response.

As Javascript can't touch file upload fields (security considerations, of course), you'll probably need some sort of Flash/Javascript/etc. application to handle the file uploads if you wish to add this functionality.

Yeah, like I meant: It is not straighforward 😃

there are some prebuild packages out there though! Not sure whether they are free or $$

Yeah I will probably go the route of a premade progress bar using ajax or perl. It's just that my users may upload up to 10MB of data per post and I really want something that will let them know how the progress is going, and I figured flushing text to the screen would be easier and require less coding, but I will suck it up and get a premade progress bar or other indicator. Thanks for all your help guys!!!!!!
