RE: [PHP] $_SESSION as $key=$value
Daniel,
Rather than sending them to a new page to validate the form and then
sending them back if a field is invalid, do the error checking from the
same script.
Here's an example, a bit simple but just to give you an idea.
For a better explanation, you should read this article which elaborates
on this method:
http://www.zend.com/zend/spotlight/form-pro-php4.php
?php
if($HTTP_POST_VARS){
// check for required fields
if(!HTTP_POST_VARS['name'] || !HTTP_POST_VARS['email'])
$error_message = 'You did not provide all required fields'
}
// any other error checking you want to do
?
?php
// if error, print out error message
if($error_message){
echo $error_message;
}
?
FORM METHOD=post ACTION=?php echo $PHP_SELF ?
INPUT TYPE=text NAME=name SIZE=20 VALUE=?php echo
$HTTP_POST_VARS['name'] ?
INPUT TYPE=text NAME=email SIZE=20 VALUE=?php echo
$HTTP_POST_VARS['email'] ?
and so on
INPUT TYPE=submit NAME=process_form VALUE=Submit

Im really struggling with $_SESSION. Im trying to program smarter and

Ive submitted several emails dealing with this function and I apologize
for beating a dead horse, so to speak.
I have a form with a few form fields. Im working on an error function
that will take the data that was entered and pass it back to the form so
that the user will not have to input the data again. If an error is
found I use the header function to go back to the form. Im having

I think this may be because you did not include echo in:

so try this:
input name =fname type=text value= ?php echo

Re: [PHP] $_SESSION as $key=$value
Change error reporting in the php.ini to NOT include notices.
Echo out the variable
echo ( $_POST['fname'] );
All the notice is telling you is that $HTTP_POST_VARS['fname'] doesn't
exist, which it isn't if you haven't posted it to this page.

and when running, I recieve
Notice: Undefined index: fname
This is because when the form is first submitted, nothing has been
submitted, and thus $HTTP_POST_VARS['fname'] has no value. PHP is
simply warning you that you're trying to use an unitialized value.
Check the value first and you'll not have a problem with it:
?php
$output_fname = isset($_POST['fname']) ? $_POST['fname'] : '';
?
input name =fname type=text value=?php echo $output_fname ? /
If the first line looks odd, check out:
http://ca2.php.net/manual/en/language.expressions.php
You could just turn down your error reporting, but all that does is
hide from you the fact that you're using code with problems in it. You
should make sure the code executes in a development environment with
full error reporting on without warnings or notices, before you turn off
error display on the production box.
