PHP and Javascript question

Anon

Here's a short function I wrote to implement my own "Back" button. Note that you could also add more buttons using the same scheme. The table allows me to nicely center them on screen.

/* ---------------------------------------------------------

Format and return table with one Back button

------------------------------------------------------- */

function btn_GoBack($Caption = "<< Go Back", $Color="goldenrod")
{

$table_button = "
<TABLE ALIGN = CENTER BORDER=3 CELLPADDING=5 CELLSPACING=5 WIDTH=\"25%\">
<TR>

<TD ALIGN=LEFT BGCOLOR=\"$Color\"><A href=\"javascript: history.go(-1);\"><b>$Caption</b></A></TD>

</TR>
</TABLE>
";

return $table_button;

}

You can easily implement this function and put this button anywhere you want on a form, e.g.,

echo btn_GoBack();

The issue is, the button will do nothing if the user has JS turned off. (Hey, it's a chance we all take, right?) But HTML supports the NOSCRIPT tag for just such an occasion. This allows you to alternately inform the user that they have JS turned off and that the button won't work.

The question is, where do I put the NOSCRIPT tag? I tried placing it inside the function, but it didn't work -- generated an error.

i don't know much at all about javascript but could you put the function and the noscript tag in an include file and then just use <?php include("goback.inc"); ?> for where you wanted the button?

Anon

I don't know. I'll give it a try. I didn't know you could just include a file and get its functionality without actually calling the function. What if you have more than one function in that file?

Anon

Yes u can, I dont include(); but I require(); a file that has over 25 functions of PHP in them, just because you include(); / require(); a file, does not mean the functions will be used / ran by doing that.

It just lets them be used at anytime.

Sorry, never understood that thingy. The manual is as clear as mud on "Require."

As an old C programmer, I just plod along with my includes. What did you mean by saying "does not mean the functions will be used" ?

I like to stick all similar functions in the same file and then just include it when I need it in another module. Is this what you were refering to?
