[SOLVED] $_POST question

[mjurmann]

Hello. I have a hidden input field on a form that obtains its value by using the $_GET['prevID'] function and grabbing the value for 'id' from the previous URL pagename.php?id=123. 

 

I echoed out $_GET['id']; in the body and it echos out the correct number. This tells me that the get variable is intact as the data is transmitted between this page and the last.

 

When I submit the form with the hidden input field, the $_POST['newID'] from the hidden input field does not echo out on the next page. Instead, the $_POST['newID'] 's value is NULL or "". Can someone help me as to why the value is getting lost like this?

 

This is very strange because when I $_POST['Username'] and $_POST['Password'] on the next page, these two echo out fine. It's only $_POST['newID'] that seems to be empty, even though it clearly is being populated by $_GET['id]; from the previous URL.

 

Thanks so much...

 

<?php if ($_GET['prevID'] != NULL) { echo "AHHHH";?>
<input type="hidden" name="newID" value="<?php $_GET['prevID'];?>" />

<?php if ($_GET['prevID'] != NULL) { echo "AHHHH";?>
<input type="hidden" name="newID" value="<?php echo $_GET['prevID'];?>" />

OR:

 

<?php if ($_GET['prevID'] != NULL) { echo "AHHHH";?>
<input type="hidden" name="newID" value="<?=$_GET['prevID']?>" />

Metro - I have been trying to figure this out for hours upon hours.

 

Thank you so much. You're my hero of the day!

I think you missed a ? from the start of the php code starter.
