Arguments in PHP function declaration

Parksy · 07-02-2004, 10:01 PM

I'm not very good with php but I'm trying to modify a cpgnuke module. I'm writing a new function that looks like this:

Code:

function drawbox($title, $content, $boxid, $btn[0], $btn[1] ) { code in here }

However, because of the array stuff, I get this error:

Code:

Parse error: parse error, expecting `')'' in file.php on line xxx

When I call the function, I want to put each array element in as an argument (there will be more than just the two elements of the array). I need to use arrays because of what I do inside the function.

I've tried looking at the online php manuals, but I don't really know what I'm looking for.

If that's the decelaration, i think that's the problem.
You should change it in:

Code:

function drawbox($title, $content, $boxid, $btn1, $btn2 ) { code in here }

Is there no way to put an array in the declaration? What I plan to do is put constants (numbers/strings) in when I call the function, but then have the function use those as parts of an array. I guess I could do this:

PHP Code:



$btn[0] = $btn1 
$btn[1] = $btn2

for all the elements I want to put into the array, then manipulate the $btn[] array. I will try it to see if it works. It that the only way to do it?

What the function is doing is making up to three javascript anchors in a box. I want to do a 2d array where one column is the anchor text (<a>textthatgoeshere</a>)and the other column is an argument for the javascript function. I'm going to do a while loop so that anchors are created while the anchor text is not 0. That way I can use the function to make 1, 2 or 3 anchors (or more if I make a bigger array and have more function arguments). I figure the easiest way to do this is with an array.

Here's what I ended up doing. It works fine, but it still seems a little ugly.

PHP Code:



function drawbox($title, $content, $boxid, $btn1, $btn2, $btn3, $btn4, $btn5, $btn6) { 
$btn[1][0] = $btn1; 
$btn[1][1] = $btn2; 
$btn[2][0] = $btn3; 
$btn[2][1] = $btn4; 
$btn[3][0] = $btn5; 
$btn[3][1] = $btn6; 
//rest of function 
}

Why do younot call your function with an array like :

PHP Code:



function drawbox( $title, $content, $boxid, $btn ) { 
//rest of function 
} 
 
$btn = Array(); 
$title = "something"; 
$content = "something"; 
$boxid = "something"; 
 
/* code to fill $btn array with values ... */ 
 
//call to drawbox function... 
drawbox( $title, $content, $boxid, $btn );

Yeah that should work the same. I guess it's just a decision of whether to have the extra lines in the drawbox() function or the main function.

Thanks for the idea.
