Fatal error: Call to undefined function: filter_input()

[keaauBoy]

I am attempting to write PHP to send form data to email. I completed a Lynda.com tutorial "Introducing PHP" by David Powers

When I test the Pges on my machine with xampp installed, everything works. I have no mail function on my msachine so I uploaded to a folder on my website to test.

I get the above error 'Fatal error: Call to undefined function: filter_input()' and the email format validation does not function. Can someone help me?formTest.phpmail_process.php

What version of PHP are you running on the site (echo PHP_VERSION;)? What does phpinfo output?

[keaauBoy]

PHP 5.5.28

I'm not sure how to access phpinfo output

[hansford]

What requinix is referring to is one of these 2 functions as either one will return the php version you are using.

echo phpversion();
echo phpinfo();

[keaauBoy]

Used  <?php echo phpinfo();?>  got a very large document with all kinds of info

[requinix]

Yeah, there's a lot.

 

1. Near the top is probably a "Configure Command". What is it?

2. Is there a section named "filter"? If so, what does it include?

[keaauBoy]

Yes, see attached JPGs

Who is your webhost? You're probably going to have to bring this up in a support request.

According to this post, for what appears to be the same issue, the OP found that his host supported PHP5 but parsed php files using PHP4 by default. He solved the issue by naming his files with a .php5 extension. I know some hosts also allow you to set the default parsing method.

I would hope to hell there is not still webhosts running PHP4. But I know I'm probably wrong...

[mac_gyver]

the OP's phpinfo() output lists a Windows 7 Pro operating system, which is probably his development system, not the web host where he is having the error at.

 

so, what that output from a phpinfo() statement on your web hosting or was that on your localhost xampp system?

[keaauBoy]

The info I gave is the output from my xampp on my machine. He is the test from my ISP

Looks like you are right Siteserver is running PHP 4.4.8. What know?

[scootstah]

Who is your web host?

 

Refer to the post that Psycho referenced to see if that applies to you as well.

My web host is Siteserver. I have contacted them about the fact that PHP 5 was released in 2004 and they are still using PHP4. I might be looking for a new ISP

I was abble to upload my php pages to an associates server who supports php 5. Everything worked perfectly including the email format validation. However when I clicked the submit button the page returned to the intitial format with blank fields in the form. When I test the pages on my xampp server on my machine and hit submit it brings up the thanks page. I know I don't have server side 'mail' capabilities but the page has code that should at least give me an error message 'Sorry your mail could not be sent.' I am not sure of the code to authenticate...... authenticate = '-fwalterhughes@hawaii.rr.com';. All who helped with the last problem with my web host, thank you. Could you help me with this final problem?formTest.phpmail_process.phpthanks.php
