simple question

I have a form with a combo box, what Im trying to do is add a hidden input field so I can store the primary key (CatID) in it, any ideas, here's what I have to start with

<? echo "<input type=\"text\" name=\"CatID\" value=\"".$result["CatID"]."\">";  ?>

<? print "<input type=\"hidden\" name=\"CatID\" value=\"{$result['CatID']}\">";  ?>

You may or may not need the braces around the $result so maybe this will work if the above doesn't...

<? print "<input type=\"hidden\" name=\"CatID\" value=\"$result['CatID']\">";  ?>

I tried the 1st one and I got value="" for the hidden field, let me try the second

How about this... this is how I would do it.. lol

<? print ("<input type='hidden' name='CatID' value='$result['CatID']'>");  ?>

or if that doesnt work, try splitting it onto a couple lines.. messier, but tends to work..

<?
   print ("<input type='hidden' name='CatID' value='");
   print ($result['CatID']);
   print ("'>");
?>

The reason you got the parse error on the previous reply was the parenthesis were left off.. the format for a print is

print ("hello");

or for a variable

print ($myvariable);

Hope this helps!

I did your method, but the value of CatID, when I press submit, the variable is empty

print ("hello");

That is false! You don't need the () with print as it is not a function but a language construct. So there is nothing wrong with the statement...

print "hello";

And what's more the statement...

$cat_id = $result['cat_id'];
print"<input type=\"hidden\" name=\"CatId\" value=\"$cat_id\">";

Will work fine too.

What is sounds like to me...is that the $result['cat_id'] or whatever isn't getting returned properly.

On your form do an echo $result['variablename'] to see if there is a value for it cause it sounds to me like you have an empty variable.

Ok..didnt know.. I was always taught you had to have the () on there... and never had reason to doubt it or look it up...
