PHP3 and the HTML Form

Is there an array in PHP that keeps all the variables that the user entered in the form, like $name, $email, etc?

The purpose is: send an email to the webmaster saying:

$name: John Richard
$email: john@richard.com

So, if I chance the name of the variables, or if I add another variable in the form.. it works..


Thanks

I don't know what your problem is, but form data allready gets passed to the result page in subsequent variables.

So if you build a form like this

<form method="POST" action="result.php" name="mailform">
Name:<input type="text" size="30" name="frm_name"><br>
Email:<input type="text" size="30" name="frm_email"><br>
<input type="submit">
</form>

And you would submit this form with John Richard as Name and john@richard.com as email, the variables $frm_name and $frm_email contain the data entered in the form, in this case:

$frm_name="John Richard" $frm_email="john@richard.com"

I need an array that keeps all the names and values of the form.

So, I don't need to know all the variable names to send the e-mail, because I'll have all the form field values in this array..

In perl, I would get the string "?name=value&name2=value", split and put it in an array..

How can I do it in PHP??

Thanks

Check the manual for $PHP_POST_VARS

Actually, it's $HTTP_POST_VARS if your form uses the POST method, $HTTP_GET_VARS for the GET method.

Thanks, Alan. Can blame my memory on all the cough medicine URL

Hey, I knew what I /meant/ to write....

So..

I put the command

<? print "$HTTP_POST_VARS - $HTTP_GET_VARS"; ?>

and it prints

Array - Array


So.. I think these stuff is not available in my ISP... or am I doing something wrong?

No, that's what you should get :0

$HTTP_POST_VARS (and GET) are arrays. They contain in data passed by POST and GET methods respectively, with the name/value pairs as the index and data respectively.

For example, if you pass the query string ?this=that&those=these
then $HTTP_GET_VARS[this] would contain the value "that" and $HTTP_GET_VARS[those] would contain the value "these"

Alternately, if you use a form you would use $HTTP_POST_VARS instead. In your application, all you would need to do is to use EACH across the $HTTP_POST_VARS array to get the keys (since you say you want to be able to change the form.)

$HTTP_POST_VARS and $HTTP_GET_VARS are associative arrays (see the documentation for a description), containing the field names and values passed from your form. Use the each() construct to walk through them:

while(list($var, $val) = each($HTTP_POST_VARS)) {
[do stuff]
}

On each iteration of the loop, $var and $val will have the name and value, respectively, of a field in your form.

Isn't that what I said URL

But what if you get another array inside the form from, for example, multiple checkboxes/selects within a group?
That gets a bit more complicated when only using HTTP_POST_VARS.
Why not just catch all the variables (by name) on a reload (after submit) of the page on which you then also perform a mail() function and clear up the form again.
I have good experience with that. Anyone any other ideas?

PAV,

You make good points. In fact, that is exactly what I do.

However, go back and read the original question. He wants to be able to add a field to the form without modifying the action script. To do that you have to have your form in an array, either one he creates or $HTTP_POST_VARS.

I don't mean this as a flame, but I've read many posts from you recently, and you give good advice except that your responses seem to not take into account special needs as defined by the person posting the question.

The way you have solved a problem is not always the BEST way for everyone.

I'm sorry if that's the impression I made, it was surely not my intention to do so...

But isn't this still a discussion forum? URL

Thanks guys!

Now.. that worked.. you're the best. Now, I don't know if I dedicate myself to ASP or to PHP.

But.. it's subject for another discussion..

Thanks
Luís

Maybe this won't work with what you want to do, but you could NAME all your input fields something like FIELD[], which will store all the form fields into the array FIELD, and can be accessed with a for loop like:

for($x=0;$x<$count($FIELD);$x++)
{
do stuff for each $FIELD[$x]
}

You wouldn't know what each value was for though, is the only problem.
