echo Array question

[listenmirndt]

so if I have a POST,

which is like,

<textarea name="somename">text text text</textarea>
<textarea name="someothername">text text text</textarea>

and i want to echo what the name of the field is, how would i do that?

say i just want to echo the "somename" part is so that the script knows what the name of the field is, as well as the value...

I would assume that you know your form field names - how are you processing the submission otherwise? You should never use user input blindly. but anyway,

foreach($_POST as $k=>$v){
   print "Form Field Name: $k ... Value: $v<br>";
}

thanks for the reply!
what if there was only going to be one text field,

would i still need the foreach?

traq's code loops through all submitted fields, including the submit button. That's being done because you don't know the name of the field.

[traq]

right - if you don't know the field name, you just have to loop through all of them.

but if there is "only one field," I would think you would know its name.

you can output data from the field as the following

echo $_POST['field_name'];

var_dump($_POST);

is also pretty useful if you're just doing this all for debugging purposes. If you've got the xdebug module installed (I believe that's the one) then you'll have nicely HTML formatted output as well.
