Hi ppl, :)


I've stack in a part where I need to define the requirements to send email.

I have fields in my form like this:

<span class="parts"><input type="text" name="amount1" value="0" class="amount_parts" /></span>

<span class="parts"><input type="text" name="amount2" value="0" class="amount_parts" /></span>

<span class="parts"><input type="text" name="amount3" value="0" class="amount_parts" /></span>

<span class="parts"><input type="text" name="amount4" value="0" class="amount_parts" /></span>

<span class="parts"><input type="text" name="amount5" value="0" class="amount_parts" /></span>

<span class="parts"><input type="text" name="amount6" value="0" class="amount_parts" /></span>

I would define, when this input field have a value of 0, that this value is not sent with the mail function.

A part of my mail.php:

$message ="Part1 - " . $_POST["amount1"] . " parts/a\r\nPart2 - ". $_POST["amount2"] . " parts/a\r\nPart3 - " . $_POST["amount3"] . " parts/a\r\nPart4 - " . $_POST["amount4] . " parts/a\r\nPart5 - " . $_POST["amount5"] . "parts/a\r\n\nPart6:\r\n" . $_POST["amount6"]; 

.....

So, if a user fill the 3th, 4th 5th field with some number that are not 0, and leaves the 1st, 2nd and 6th field with the default value (value of 0), I would like that the mail function send only fields with numbers that are not 0.

Thx in advance! :)

Ty johnny for your answer, but, Im not so familiar with PHP, can you show just in short how to do that? :) ty in advance!

This should work:

$out = "";
for($i=1;$i<=6;$i++) {
     if(!isset($_POST["amount$i"])) {
         $_POST["amount$i"] = 0; //default value
     } else {
         $out .= "Part$i - {$_POST['amount$i']}\r\n"; //Slug here
     }
}

//out will only contain forms that were filled out

I will try it, ty Nullw0rm :)

Tried that, but I get only:

Part1 -

Part2 - 

Part3 - 

Part4 - 

Part5 - 

Part6 - 

Don't get the amounts :S

change

$out .= "Part$i - {$_POST['amount$i']}\r\n"; //Slug here

to

$out .= "Part$i - ".$_POST["amount$i"]."\r\n"; //Slug here

{}-evaluation can be good at time, but at many times it's just not the best option,
as in this case, the string inside the post brackets also needed an evaluation
I think the code is more easily read this way too.

[bukymast3r]

Worked now, ty Orjan,

but, I get also fields that have default value of 0

Part1 - 2

Part2 - 0

Part3 - 3

Part4 - 0

Part5 - 1

Part6 - 0

[Orjan]

Then it's even easier code, just do this....

$out = "";
for($i=1;$i<=6;$i++) {
    $out .= "Part$i - ".$_POST["amount$i"]."\r\n";
}
