[RESOLVED] ereg_replace using array keys and value

[scrupul0us]

Lil background:

I have a form that is stored in mysql... each of the fields a user can fill are by default filled like this:

[name]

so if theres an input box called "Employee" by default in the db it's value is [employee], now, based on the query string my form will ereg those out if ?mode=new and then they are just blank lines that the user can work with...

ok, now for my question

i need to process this form and a bunch other by submitting the form back to itself using ?mode=process... when this happens I get the $_POST array which is keyed to each of those form "element" values... since there are to be lots of forms I cant hard code any of the eregs by a particular "element name"... sow hat i need todo is this:

take the post array, search the form for each key(which is in the same [name] format) and when it finds that, replace it with that keys value

example:

Array
(
    [to] => John Smith
    [employee] => Brian Ellwood
    [fax] => 123-456-7890
    [pages] => 10
    [phone] => 098-765-4321
    [longdate] => April 27, 2006
    [re] => Testing
    [cc] => N/A
    [comment] => on
    [message] => Sample Message
)

is a $_POST dump after I array_pop the submit button value out... now im left with just the form values

so, as u can see each key is formatted EXACTLY how the default form values are... just need to ereg_replace for each array key and its value

hope ive provided enough info... any help its greatly appreciated!

and just for simplicity, the string that I'm working with is:

$data = $row['data'];

THANKS!

i do not understand your question at all. you have a form with field names that correspond to the field names in your database? when the form is submitted you want to collect the data and insert a new row into the database? what do you need to replace? you have all of the data in the POST array that you can use to contruct your INSERT query.

example of one of MANY forms stored in MySQL:

<textarea id="message" name="message" style="width:645px; height:680px;">[message]</textarea>

NOTE the default value for the textarea "[message]"

now ill call that from the db:

//GET FORM
$data = $row["data"];

then when ?mode=new, replace all those bracket defaults with nothing

//MAKE REPLACEMENTS
$data = ereg_replace("(\[[A-Za-z0-9]*\])","", $data);

so then the user has a blank area to work with...

now we process the form with ?mode=process, get the form from the db again and instead of ereg-ing the defaults out, I need to process the $_POST array and ereg the posted vars back into the form

since the there a a bunch of forms with varying default values i cant hard code this, so somehow i'd have to loop through the keyed array and ereg_replace where the pattern is the key, the replacement is the key's value and the string is $data

hope that clears things up!

heh... answered my own question...

$data = $row["data"];
array_pop($_POST);
foreach ($_POST as $k => $v) 
{
$data = ereg_replace("(\[$k\])",$v, $data);
}
echo $data;
