Can't get MySql query result as value of text input to post to next page

TerryS

Hello,

I'm trying to use data from a Mysql query as the default value for a text-input field in a html form. I've verified that my query is retrieving a data set and that $row['schName'] contains a value. Here is the code I'm using:

<input type="text" name="schName" value="<?php echo $row['schName']; ?>" class="txtInput" />

After submitting this form, on the next page I have the following:

<?php
session_start();
$SESSION['schName'] = $POST['schName'];
?>

However, when I check either the $POST or the $SESSION array, both of them show schName as NULL.

What am I doing wrong?

Thanks for any help.

But when I submit the form and then check the $POST array on the next page, or when I try to set a $SESSION array

I doubt that, only because POST'ed variables will never be NULL. An empty string, sure, but never NULL.

Can you show us the resulting HTML of the form that's generated?

Sorry, I still get confused about what I can call "Null".

At any rate, the html output of the line of code I showed you originally is this:

It appears to me like all the necessary ingredients are there. However, when the html form is submitted the next page doesn't give me the result I'm expecting. If I do

<?php
foreach ($_POST as $key => $value){
echo "$key: $value";} ?>

the only thing I get is a key and value that were set on the initial page (the page before the one where I'm having the problem).

That should just work. Can you please show the whole form html?

I seem to have solved my problem although I'm not sure quite how I did it. The code I was showing you was carried over into one of two pages, depending on another variable. What I didn't realize at first was that I was only testing the result on the second of the two pages (2-B for the sake of explanation). In creating that page, I had just cut and pasted some code from the the 2-A page including the foreach loop. Apparently the editor I was using must have added some non-printing characters or something because the 2-A page worked correctly. When I realized that, I retyped the foreach code on page 2-b and now it works correctly. Thanks for your help everyone.
