small php question

TeviH · 12-02-2007, 03:41 PM

Hello,

I am not exactly a php expert, and this is probably a very simple thing to do. I am using http://formtoemail.com for a simple php form script on my website. I am using it to submit an order form. (not secure; no payment transaction)

The question is, how can I prevent items with a value of "val0" from being sent in the form? Basically, that just means the customer doesn't want it, so, there's no need to have that sent in the email. Since there's a pretty long list of products (about 25), it can be tiresome to look for the items with values of "val2" "val3" etc. (I need to use the "val" prefix, rather than a number).

post the code that sorts the values and sends it, thats be helpful

but im sure a simple if statement would suffice

Sure! Here:

PHP Code:

else

{

 
foreach($element_value as $value){if($set){break;} recursive_array_check_header($value);}

 
}

 
}

I have not read your script, but i think the solution is

PHP Code:

  $message='';

 
$message='hello dear customer';

????: NamePros.com http://www.namepros.com/showthread.php?t=402479
 
if (checkbox_1_is_checked) {

   $message.=' - '.append_your_item_1_here;

}

 
if (checkbox_2_is_checked) {

   $message.=' - '.append_your_item_2_here;

}

 
send_the_mail();

TeviH · 12-02-2007, 09:43 PM

I'm not sure Iknow what you mean, but it sounds like you would have me write out a special snippet of code for each form field... I would rather have a universal line of code that basically says, "if any form field has a value of "val0" do not bother writing out that information. We really don't care."

Any other ideas?

xrvel · 12-02-2007, 10:28 PM

First, name your first checkbox with cb01, 2nd checkbox with cb02, ...
(your checkboxes do not have name)

now modify the build_message() section

PHP Code:

  <?php

function build_message($request_input){

????: NamePros.com http://www.namepros.com/showthread.php?t=402479
    if(!isset($message_output)){

        $message_output ="";

    }

    if(!is_array($request_input)) {

        $message_output = $request_input;

    } else { 

        foreach($request_input as $key => $value){

            if(!empty($value)){

                if(!is_numeric($key)) {

                    $add=true;

                    if (preg_match('/^cb([\d]+)/i',$key,$match)) {

                        // if is our special checkbox

                        if ($value!='on') {

                            // if it is not checked, do not add

                            $add=false;

                        }

                    }

                    if ($add) {

                        $message_output .= str_replace("_"," ",ucfirst($key)).": ".build_message($value).PHP_EOL.PHP_EOL;

????: NamePros.com http://www.namepros.com/showthread.php?t=402479
                    }

                }else{

                    $message_output .= build_message($value).", ";

                }

            }

        }

    }

    return rtrim($message_output,", ");

}

?>

the checkboxes are not being sent as part of the data, and are really only used to make the form easier to use, from the user's perspective. Checking a checkbox just sets the quantity to "1" in the select box, but the information that is emailed is only from the select box; not the checkbox.

I don't know if any of this is making sense, so I will try to explain what I need, again: I would like to make some sort of declaration in the php that for any field with a value of "val0" do not email any information about that field. Not the name, and not the value.

Thanks!

TeviH · 12-03-2007, 11:52 AM

solved!

simple solution (isn't it always?):

instead of having the "0" value be "val0", I just left it blank... (thought I needed it there)

You're right. If the select box has "0" value, it does not need to be appended in the mail
