Function Calling

[nctfleetlist]

I am using simple machines forum, and by placing a link to ssi.php in the top of my php page

<?php require_once('/forum/SSI.php');?>

I am able to use some ssi functions. My problem is calling another function from within a function. My first function is this:

<?php

	$allowed_groups = array(1,5);
	$can_see = FALSE;
	foreach ($allowed_groups as $allowed)
		if (in_array($allowed, $user_info['groups']))
		{
			$can_see = TRUE;
			break;
		}

	if ($can_see)
	{
		echo '
			<div>
				this is text that i want certain groups to see
			</div>';
	}
	else
	{
		//message or section to show if they are not allowed.
		echo 'this is text that i dont want certain groups to see';



	}
	?>

 

This is my second function:

<?php ssi_welcome(); ?>

 

I want to put the second function inside the first function, like so:

if ($can_see)
	{
		echo '
			<div>
				<?php ssi_welcome(); ?>
			</div>'; 

 

this just gives me the "<?php ssi_welcome(); ?>" displayed on the actual site, it is not calling the separate function.

 

I have tried different approaches, e.g. $function ssi_welcome;  but all it does is display this as text as well..

 

Please can some one point me in the right direction. Thank you

the first code you posted is not a function. a function starts like this:

 

function someFunctionName() {
     // Function contents

}

 

 

[BlueSkyIS]

but perhaps the solution is as simple as this?

 

echo '<div>' . ssi_welcome() . '</div>';

thanks for your quick reply, I am still learning php so got confused with what is and what is not a function lol.

 

doing what you suggested I either get "

Parse error: syntax error, unexpected '>' in [full path to my file name]

 

If I use a backslash (\) to quit the apostrophe's (') it simply prints the text as is:

(' . ssi_welcome() . '

'; )

[Mr Hyde]

What kind of output are you expecting from ssi_welcome()? Does it print something to the screen? Does it return a variable? Do you know?

[nctfleetlist]

As far as I am aware it prints something to the screen.

 

In normal circumstances

<?php ssi_welcome(); ?>

 

displays as

 

"Wecome Guest"

or if user is logged in

 

"welcome member_name"

[BlueSkyIS]

can you post the updated code and the line number referenced in the parse error?

[nctfleetlist]

Parse error: syntax error, unexpected '>' in /home/nctflee1/public_html/account/test.php on line 24

<?php

	$allowed_groups = array(1,5);
	$can_see = FALSE;
	foreach ($allowed_groups as $allowed)
		if (in_array($allowed, $user_info['groups']))
		{
			$can_see = TRUE;
			break;
		}

	if ($can_see)
	{
		echo '
			<div>
				<font class="font">'<div>' . ssi_welcome() . '</div>';
</div></font>



			</div>';
	}
	else
	{
		//message or section to show if they are not allowed.
		echo '';



	}
	?>

 

thanks for your help so far

<?php

      $allowed_groups = array(1,5);
      $can_see = FALSE;
      foreach ($allowed_groups as $allowed)
         if (in_array($allowed, $user_info['groups']))
         {
            $can_see = TRUE;
            break;
         }
         
      if ($can_see)
      {
         echo '
            <div>
               <font class="font"><div>' . ssi_welcome() . '</div>
</div></font>



            </div>';
      }
      else
      {
         //message or section to show if they are not allowed.
         echo '';

         
         
      }
      ?>

 

That should work...

[nctfleetlist]

It worked a treat!!

 

Thank you ever so much for your time and help Mr Hyde, it is most appreciated!!!
