If Then Echo Session

Hi,

I need help :-)

If there is no Validate entry show the session.

If
<?php echo(ValidatedField("bilderHinzufuegen","imageInfo")) ?>

is empty

show
<?php echo $_SESSION['name']; ?>

How do I write that in php, the shortest way?

This will do it for you:

<?php echo(ValidatedField("bilderHinzufuegen","imageInfo ")?ValidatedField("bilderHinzufuegen","imageInfo "):$_SESSION['name']) ?>

basically what this ternary operator is doing is printing the validated entry if it exists and if it doesn't it will print the session value

Hi dave,

this does not work, it stays the session variable, even if I change the entry.

by the way I tried to answer your question with that DFP upload size.

Denis,

I use this format all the time with VTK, especially with update forms where I need to show either the original value or the updated value if validation catches an error.

How are you using the code and for what purpose ?

Your answer worked for DFP upload size thanks.

Dave,

i am sorry, I didnt cahnge the name of the validate entrie variable :-(

I changed it and now its:

(ValidatedField("bilderHinzufuegen","photograher") not (ValidatedField("bilderHinzufuegen","imageInfo")?

It works great, THANKS

Good night,
