Functions within includes/required files

Anon

Hello,

I mus say that hte help that I have been able to get towards my previous questions has been quick and of excellent quality.

My latest question/problem is in relation to functions that reside within my require/include files.

Test.php is below

<?php

require("./SSI/Common.php"); // Header and footer functions.

html_header(); //Load the html header information.
?>

Common.php is below

<?php

// Test to see if this file has been included already.
//
//

// This function has been designed to output the header of an html document.
//
// $title has been designed to be the title of the page that is being created
// and as such is set within the calling php application.
//
//
function html_header($title)
{
echo "";
echo "<head>";
echo "<title>$title</title>";
echo "</head>";
echo "<body>";
}

// This function has been designed to output the footer of an html document.
//
//
function html_footer()
{
echo "</body>";
echo "";
}
?>

When the test.php is loaded via my web browser the following error is displayed?

Fatal error: Call to undefined function: html_header() in /var/www/html/form.php on line 5

Can anyone explain to me why I am receiving this error? Is this an ID10T error? Are my functions legal? Are the calls to them legal? Can I maintain functions within the require/include statements?

As always thank you in advance for your help

Us there some kind of call to "form.php" in any of the above files?

Then again the html_header() part looks like it requires a parameter to be passed when calling it ($title):

<?php

require("./SSI/Common.php"); // Header and footer functions.

html_header(); //Load the html header information.
?>

..
function html_header($title)
{
echo "";
echo "<head>";
echo "<title>$title</title>";
echo "</head>";
echo "<body>";
}

$title?

The code:

<?php

require("./SSI/Common.php"); // Header and footer functions.

html_header(); //Load the html header information.
?>

is form.php. It is the page that I am trying to load/generate. Even at this dumbed down state the error still exists. My limited understanding leads me to believe taht the error is not being generated by the lack of a parameter when the form is being called because PHP will just "fill" this (for lack of a better term)

I copied your code and I got a missing argument error when trying to view the form.php page. This worked:

//form.php
<?php

require("Common.php"); // Header and footer functions.

html_header("Form Page"); //Load the html header information.
?>

//common.php
<?php

// Test to see if this file has been included already.
//
//

// This function has been designed to output the footer of an html document.
//
//
function html_footer()
{
echo "</body>";
echo "";
}
?>

And if I am not mistaken php does NOT just fill in a missing argument when making a call to a function. If you want to leave it blank you need to put empty quotes.

html_header('');
