AndyB Posted June 10, 2007 Share Posted June 10, 2007 Why do I get the error? Like the post title says .. the function is never defined.

christofurr Posted June 10, 2007 Author Share Posted June 10, 2007 Explain, please. Link to comment https://forums.phpfreaks.com/topic/54919-solved-call-to-undefined-function-filter_input/#findComment-271642 Share on other sites More sharing options...
AndyB Posted June 10, 2007 Share Posted June 10, 2007 Explain, please. Nowhere in the code you posted is there anything that is the actual function you're invoking ... i.e., it's undefined.

christofurr Posted June 10, 2007 Author Share Posted June 10, 2007 I'm still confused. What must I do in order for the code to work?

AndyB Posted June 10, 2007 Share Posted June 10, 2007 I'm still confused. What must I do in order for the code to work? Read any simple tutorial on functions. How can your function call possibly work when there is absolutely no code anywhere to explain what filter_input is supposed to do?

christofurr Posted June 11, 2007 Author Share Posted June 11, 2007 W3Schools tells me that it's a predefined function. Or did I misread? They use the function the same way I do in my code. Is this site unreliable? Link to comment https://forums.phpfreaks.com/topic/54919-solved-call-to-undefined-function-filter_input/#findComment-272690 Share on other sites More sharing options...
AndyB Posted June 11, 2007 Share Posted June 11, 2007 http://ca.php.net/manual/en/function.filter-input.php I learn something new every day!! Note that it's only available as part of php5. Is that what you have on your server?

christofurr Posted June 12, 2007 Author Share Posted June 12, 2007 Yeah, my server supports PHP5, but I think it uses PHP4 to parse all scripts by default. I'll try naming the script with the .php5 extension.
