Code Runs Properly, Receive a 500 Error Message

mjanosko · March 4, 2015

I have been working on a custom form for our office to use, and I am rounding the final corner (checkboxes!) and am stuck.

I have finally gotten the code to actually function the way I want, but am greeted with a 500 error instead of the confirmation page. Maybe I'm just tired and missing something...

Of note, when I comment out the assignment and email-print for the "$features" variable, it runs without emailing the checkboxes, and gives the proper "confirmation" page.

Thanks!

but am greeted with a 500 error instead of the confirmation page.

Check you servers error logs for why you are getting that error. Or add the following two lines at the top of your script (after the <?php)

ini_set('display_errors', 1);
error_reporting(E_ALL);

There is nothing for today in any of my Event Viewer logs, and adding that code results in the same error page.

As in Windows Event Viewer? It wont be logged in there. The servers error log will be text file. For example the Apache http server writes it errors to a file called error.log in a directory called logs. The logs folder will be where you installed Apache to (eg C:/Apache/logs).

You will not be able to solve 500 Internal Server without knowing the actual error that is triggering it.

I am using IIS 7.5. I have the error_log directory in PHP.ini set to C:\ and its not creating a file.

This is what's in \inetpub\logs

Umm.. Nope does not seem to be any errors logged there, more of an access log really. I'm not an IIS user so not sure where it logs its errors to.

Have you tried setting these lines in the php.ini

error_reporting = E_ALL
display_errors = On

Make sure you restart IIS after making any changes in the php.ini. This should force errors to be displayed during run time.

Enabled both of these, restarted IIS, loaded page from a browser I don't use (to avoid completely closing my browser and clearing cache), same thing. Generic 500 error. Nothing more.

Remove the error suppression (@) in front of the mail() call and see if that throws any errors for you. Maybe?

No luck.

$features .= implode(', ', $_POST['features']);

Did you mean if you comment out that line, it works?

Try without the dot.

Also, for security, make sure you html escape the strings - the inputs may contain malicious JavaScript. Use htmlspecialchars() for this.

Couldn't care any less about security, it's internal only, and to be honest I imagine most users will tell me to get f##ked before they actually use it, but thanks!

Yeah, when I comment out that line and "

$email_message .= "Features Requested: ".clean_string($features)."\n";

it runs fine. It runs fine NOW, just returns a 500 error, but the email stills come through perfectly.

Removing the "." did not change anything. Same exact results.

I am using IIS 7.5. I have the error_log directory in PHP.ini set to C:\ and its not creating a file.

error_log needs to point to a file, not a directory. Set it to something like C:\php_errors.txt. Make sure the file is writable by IIS as well.

It is, to both, just couldn't remember the name of the file in the ini when I posted.
