For Every $_POST

[tarun]

Basically Ive Got Lots Of POSTs For A Multi-File Uploader

 

It Needs To Run Through All The POST Variables

eg

file_1

file_2

file_3

etc.

 

I Would Think It Could Be Done With for Or foreach

But Im Not Sure How So If Anyone Does Or Can Point Me In The Write Direction Please Post A Message Here

K Thnx

Try this:

 

<?php

foreach ($_POST as $key => $val){
   echo $key.'-'.$val.'<br>';
}

?>

If you know what the last number will be, it's easy.

 

This is just one way that comes to mind:

for ($index = 1; $index < 30; $index++) {
echo $_POST['file_' . $index];
}

 

If you don't know the last number, use while($_POST['file_' . $index]), and increment $index.

Unfortunatley None Of These Methods Worked

The First Two Provided No Output And This:

<?php
$index=1;
while($_POST["file_".$index]<=10){
echo "File $index Uploaded<BR>\n";
$index++;
}
?>

 

Just Listed An Everlasting List Of Numbers. eg.

File 1 Uploaded

File 2 Uploaded

File 3 Uploaded

File 4 Uploaded

File 5 Uploaded

etc.

<?php

foreach($_POST as $key => $value) {
// $key contains the POST field name from the form
// $value contains the file name input (may want to filter here..)

// After filtering, upload file...
}

?>

Yeah, you actually have to submit the information for it to show up. The code I provide should be on the file where the form action is directed at.

Yes I Know 

 

However I Shall Try Again

This Works As Mentioned By "chigley" And "pocobueno1388 "

 

<?php
foreach($_POST as $key => $value) {
}
?>

 

Is There A Way How I Can Make It More Advanced Since At The Moment It Uses All The $_POST Variables

How Do I Do It So It Only Uploads Fields With file_1 , file_2, file_3 etc. Up To An Unlimited Amount

[trq]

<?php
foreach($_POST as $key => $value) {
  if (substr($key,0,4) == 'file') {
    echo "$key => $value";
  }
}
?>
