[RESOLVED] File contents of $_POST disappearing?

larsr

Hi all,

I have the following script:

index.php:

if( isset( $_POST[ "submitAddItem" ] ) ) {
  foreach( $_POST as $tag => $val ) {
    print( "tag: " . $tag . "<br>val: " . $val . "<br><br>" );
  }

  print( var_dump($_POST) );
  print( "<br>" );
  print( "file error: " . $_FILES["picture"]["error"] );

}
include( "form.php" );

and the form file it is calling looks like this

form.php

<html>
 <head><title>problem</head>
 <body>

  <form name="TheForm" action="<?= $_SERVER[ "PHP_SELF" ] ?>" method="post" enctype="multipart/form-data">
   <input type="text" name="random" />
   <input type="file" name="picture" value="photo" />
   <input type="submit" name="submitAddItem" value="Preview" />
  </form>

 </body>
</html>

The problem is that the file portion is disappearing somewhere in $_POST.

The results for submitting the form and inputting ex. blahblah to the text form looks like this:

tag: random
val: blahblah

tag: submitAddItem
val: Preview

array(2) { ["random"]=> string(6) "blahblah" ["submitAddItem"]=> string(7) "Preview" }
file error: 0

So as you can see the file is not generating any errors, but the contents of "picture" are not getting into the $_POST array.

I am really really confused. This problem is part of my bigger project, but I isolated it this far and just don't get what in these lines is going wrong.

The file should be in $FILES not $POST, I think.

You're right, it can be found there.

But -- how come then this following script DOES show the filename in the POST array (all in one file):


<?php

if( isset( $_POST[ "doit" ] ) ) {

 foreach( $_POST as $key => $val ) {
 print( "key: " . $key . ", val: " . $val . "<br>" );
 }

} else {
 print( "i wasn't submitted" );
}

?>

<html>
<head></head>

<body>

 <form name="theform" method="post" action="<?= $_SERVER["PHP_SELF" ]?>">
 <input type="file" name="picture" />

 <input type="submit" name="doit" value="push me">
 </form>

</body>
</html>

That form isn't set up as multipart/form-data so I'd suggest it probably isn't actually getting the file data or not getting it in any usable form.
