[Resolved] RTF radio str_replace function

mikotondria

Hey folks,
I am currently developing a series of RTF templates with php/MySQL..
The replacement of text and textareas is straightforward, but when I have an answer from radio button, then I want to populate either the 'yes' or 'no' box on the real form with an X..
Eg:

Do you like eggs:
X YES ___ NO

I have done this by putting a holder in for ech box in the RTF template like so:

Do you like eggs:
%eggs_y% YES %eggs_n% NO

and doing a simple:

if ($eggs == "yes"){
$output = str_replace( '%eggs_y%', 'X', $output );
$output = str_replace( '%eggs_n%', '__', $output );
} else if ($other_cases == "no"){
$output = str_replace( '%eggs_n%', 'X', $output );
$output = str_replace( '%eggs_y%', '__', $output );
}

There are literally hundreds of these in my project, so obviously I want to write a function where I can just pass the field name to it, and it spits the right '$output' back..like:

do_radio(eggs);

I am thinking something like...

but this is unsuccessful...

Im sure its just a syntactical problem, if anyone has any pointers or advice, Id be very glad to hear it 🙂.

Many thanks in advance.

<?
$rtf = '
Do you like eggs?
%eggs_Y% YES %eggs_N% NO

Do you like bacon?
%bacon_Y% YES %bacon_N% N

Do you like pancakes?
%pancakes_Y% YES %pancakes_N% N
';

function do_radio($field, $boolean)
{
	global $rtf;

$boolean_swap = array('Y' => 'N', 'N' => 'Y');
$rtf = str_replace('%' . $field . '_' . $boolean . '%', '_X_', $rtf);
$rtf = str_replace('%' . $field . '_' . $boolean_swap[$boolean] . '%', '___', $rtf);

return $rtf;	
}

echo '<pre>' . do_radio('bacon', 'Y') . '</pre>';
?>

Hey Mike..
That looks splendid, mate - many thanks..
Couple of questions..

My version of the 'rtf' string is the document.rtf template that I am opening with fopen, replacing the tags and then outputting with the appropriate headers..
I am calling this '$output'.
So, can I just subsitute like..

function do_radio($field, $boolean)
{
global $output;

$boolean_swap = array('Y' => 'N', 'N' => 'Y'); 
$output = str_replace('%' . $field . '_' . $boolean . '%', '_X_', $output); 
$output = str_replace('%' . $field . '_' . $boolean_swap[$boolean] . '%', '___', $output); 

return $output;

}

Also, I see where you cite a 'bacon' example, we need to pass 2 variables to the function - the field name another..in the example, Y.

Would I still need an 'if' statement to read the value of that field, then pass that to the function, like so :

if ($bacon == "yes"){
do_radio(bacon, Y);}
else {
do_radio(bacon, N);}
}

Sorry if this seems a daft question, I got a little 'lost' in the boolean array thing. 🙂

Thanks again for your help, I really appreciate it !!

Cheers,

Mike.

In the do_radio() function you originally wrote there are four problems:

1) You never tell it what $output is.
2) You never do anything with the altered $output.
3) Variables aren't interpolated in single-quoted strings
4) If the strings were double-quoted, PHP would find what look like variables named $field_n and $field_y instead of $field.

function do_radio($field, $output){
if ($field == "yes"){
    $output = str_replace( '%{$field}_y%', '__X__', $output );
    $output = str_replace( '%{$field}_n%', '_____', $output );
} else if ($field == "no"){
    $output = str_replace( '%{$field}_n%', '__X__', $output );
    $output = str_replace( '%{$field}_y%', '_____', $output );
}
return $output;
}

its ok, I sorted it...
simply:

($bacon == "yes") ? do_the_radio(bacon, 'Y') : do_the_radio(bacon, 'N');

Hit me up if you've found this thread from an RTF replace type search and I'll help 🙂

Thanks again, each.

$bacon = do_the_radio($bacon, ($bacon=='yes') ? 'Y' : 'N');
