reading a web form for input variables

sde · 08-11-2003, 01:56 AM

i want to read in all the field names of a form to an array in php.

example of page i want to read:

Code:

<form method=post action="somepage.html">

Name <input type=text name="realname"> <br>
Email <input type=text name="email"> <br>
Comments <text area name="comments"></textarea>
</form>

i would like to read this page and read the field names into an array

PHP Code:


			
<?

$field[0]="name";

$field[1]="email";

$field[2]="comments";

?>

i will read the entire page into a variable, then i think this is the pattern i need to match

input=["]?[a-zA-Z_]+["]?\s

but i am not sure how i would bring all those matches into an array.

what about the _POST[] array, they are all there, if you use method=post

_POST['name'] will be the input in the name field.

I could be wrong on this one, but I destinctly remember somethign about that.

the target page i am reading is on another web server.

can someone help me with a regular expression? i can move on with this project if i can just extract the url that the form submits to.

i need to match:

action=somepage.html
action="somepage.html"

theoretically, .. will this match it?\

Code:

\saction=[\"]?(.*)[\"][\s>]

it would have to match:
<space>action=(quotes or no quotes)(any url)(quotes or no quotes)(space or bracket)

i just made that expression as i was typing this post, so i'll go try it now.

Code:

preg_match("!\s+action=\"?(.*)\"?\s*.*>!iU",$contents,$matches)
