Hello,

I was given this coding a long time ago from this website by a user and I have used it for years on one of my website. I have built another website and used the same coding. However, when I pull up the page that has the contact form on it, it says "Call to undefined function: html_entity_decode() on line 218. So, I can't figure out why it won't work on the new website. Line 218 has

$userName = html_entity_decode($userName);

But, here's the first half of the coding for the script:

<?php

And what version of PHP is this site running on?

[akin0505]

Not sure. How would I find out?

[eriksmoen]

create a test page and put <? php_info(); ?> in it

[akin0505]

It says "Fatal error: Call to undefined function: php_info() on line 7" which contained

<? php_info(); ?>

[laserlight]

The function to use is [man]phpinfo/man, or more specifically, you can print the return value of [man]phpversion/man.

[big_nerd]

You are using Short Tags, Try using Long Tags, on an outside chance the server has another system parsing the output of <? xxx ?>

Try using <?php phpinfo(); ?>

Regards,

Michael (big.nerd)

[akin0505]

Okay, it's using PHP Version 4.2.2

[Weedpacket]

And the manual entry for [man]html-entity-decode[/man] says that it was introduced in PHP 4.3. Read that page for information useful to you, and ask yourself why this host hasn't upgraded their PHP installation in more than four years.

[akin0505]

Haha, the host owns his own web business who doesn't do good work at all, so I'll have to get after him about that.

But thank you all!

[Houdini]

Change Hosts...it is much easier.
