The Error: This file contains HTML or script code that may be erroneously interpreted by a web browser

This is a common error when uploading files that the MediaWiki system does not allow.  By making some minor changes to the MediaWiki LocalSettings.php file, we can fix this.

For demo purposes, I'm going to make our system recognize SWF files (by default these are disallowed):


The Issue

If you've ever made PHP scripts to process data within a LAMP environment (Linux, Apache, MySQL, PHP) then this happens a lot.  In the following example, our HTML form will allow the user to specify a date (so excludes hours, minutes and seconds).  For demonstration purposes, I'm going to be using the European date format so DD/MM/YYYY.

The Solution

The Issue

Basically you have a HTML form with an input field type of 'FILE' (ie. <input type="file" name="file_to_upload" />) and want a PHP file to process this.  This example applies to a Linux Apache MySQL PHP (LAMP) environment.

 

The Solution
1.  The first thing to do is check that your HTML form is setup to do this:

The Issue

You have a PHP page which generates a HTML form.  When the user submits the form, you want the same PHP page to process the data.

Solution

I've seen a lot of people write CGI requests but if you left the action attribute blank, this would do the same thing:

 

copyraw
<form method="post" action="">
...
  1.  <form method="post" action=""> 
  2.  ...
