ok iget the following error:

invalid arguement for foreach on line 71

my code is:

<?php
// This will warn the user if there are html vars in his data
foreach ($_POST as $PostVar1) { //line  71
    $PostVar2 = htmlspecialchars($PostVar1);
    if ($PostVar1 != $PostVar2) {
        $g++; }
//This will make it so it only shows the error one time...
     
} ?>

It means there is no data to iterate over in $_POST.

darkfreaks · March 9, 2008

yeah i tried making sure if the variables were set first i get

"please enter a title and description"

invalid arguement for foreach on line 71

why wouldnt post data set into the post?

Daniel0 · March 9, 2008

Try to add var_dump($_POST); before the loop and see what it outputs.

darkfreaks · March 9, 2008

still outputs the error

Daniel0 · March 9, 2008

Yes, but the output of that should tell you what the contents of $_POST is. So what's the output?

darkfreaks · March 9, 2008

Checking for errors...

Warning: Invalid argument supplied for foreach() in /home/.vermin/epicso/epicso.com/test/mk-quiz3.php on line 71

Error: You must have a title.

Error: You must have a description.
