Thinking isset() Hates Me

[Ukoku]

I'm have a bit of trouble with the isset() code. The goal is to click a link (or a submit button) and have it travel to another page. The page is only viewable if the link has been clicked. However, my code doesn't seem to understand that I'm clicking the link....

From the main page:

<form action="view.php">
<input type="submit" value="submit" name="submit">
</form>

From the second page:

<?php

if(isset($_POST['submit'])) {

//database connection info is here
//table loop is here

} else {
echo "The reviews are currently unavailable.";
}

?>

I always receive the else.

Maybe there's another way to do this code?

Ahh... figured it out. If a variable is passed through the url it is a $GET variable, not a $POST. Of course. The working code is therefore:

if(isset($_GET['view'])) {

...etcetera.

you need a method="post" in your form-tag 🙂

i also tend to add the enctype="multipart/form-data" attribute to the form-tag.

your first code is correct, except your form is missing a parameter:

<form action="view.php" method="post">
<input type="submit" value="submit" name="submit">
</form>

then use if(isset($_POST['submit'])) {

Thanks, you two, but I ended up going with a link instead of a submit button anyway.

<a href="view.php?view=TITLE">

Because it sends it though the server, it counts as a GET, it seems.

Now I just have to make the second page print only those with the correct TITLE.... (Just did it. ;P )

yes, if you do not specify a method it defaults to GET.

but using this method isn't as secure as using post.
always keep security in mind when using GET. try using POST whenever possible.
