Errors as soon as I install

Everything is ok on your side Trishah,
Your php configuration is configured by defaut to show notice errors
in your php.ini file i think you will have the error_reporting set to:
Default Value: E_ALL & ~E_NOTICE

there’s other values it can take
Development Value: E_ALL | E_STRICT
Production Value: E_ALL & ~E_DEPRECATED

More details can be found here
http://php.net/manual/en/function.error-reporting.php

but anyway, the developper of the plugin should verify if the variable exist first before using it, it’s only natural

in line 466
if($_POST[‘which’]==’new_portfolio_item’){

it should be
if(isset($_POST[‘which’]) && $_POST[‘which’]==’new_portfolio_item’){

You can do the same for the rest,

There’s another way to solve this but i don’t recommend it,
put this
error_reporting(E_ERROR | E_WARNING | E_PARSE);
right after <?php at the beginning of the file

it will omit the notice errors but as i said i don’t recommend it, it’s better to fix them

Hope it helps.

Sure of course,
I’m using XAMPP on windows,
in the C:\xampp\php\php.ini file
i have the error reporting set by default to :
error_reporting = E_ALL & ~E_NOTICE & ~E_DEPRECATED

This will show all errors, except for notices and coding standards warnings (Code that will not work in future versions of PHP)

The show the notices use this:
error_reporting = E_ALL | E_STRICT

create a file on your www ( htdocs ) folder and write

<?php
if($_GET[‘t’])
echo “Hello World!”;
?>

you should get this
Notice: Undefined index: t in C:\xampp\htdocs\post.php on line 2

when visiting
http://localhost/post.php

Hope this helps,
And sorry for my language 😀

Best Regards.
