Using Regular Expressions to find and replace tokens

[rkdiekhoff]

Hi,

I'm using tokens in HTML form fields as placeholders that get swapped for data derived from a database. For example:

<input type='text' name='txtAddress' value='[txtAddress]'>

For any field that does not get filled in with content from the database, I would like to create a function that replaces all remaining tokens with a blank --- considering the format of the token would always be: [TokenName] with TokenName being variable.

Is there a way this can be accomplished using regular expressions and str_replace()?

Thanks,

here is an example of where it would work. say you have a table called test, with fields, field1, field2, field3, field4.

$q = "SELECT * FROM test WHERE something";
$r = mysql_query($q);

$data = mysql_fetch_array($r);

extract($data);
//now $data['field1'] is $field1 etc...

preg_replace("/value='[(\w+)]'/e", "value='$\\1'", $html);

where $html is the source of the html page.

something like that should work, i didnt test it but i think its right. see how it goes.
