Hello,
I want to use this snippet to make sure the fields in a form are ok before processing it.
Code: <FORM method="post">
To:
<input type="text" name="name" size="40" value="<?php if($name) { print $name; } else { print "Insert Name"; } ?>">
<input name="action" type="submit" value="Update Form">
</FORM>
It works, but I don't understand why.
The if statement is checking for the variable $name, but I haven't used the code that I would normally use.
What I see in all my tutorials would lead me to use...
$name= $_POST['name];
So, I'm confused as to where the $name variable is being found.
Thanks for your patience
$variable = $variable
