[SOLVED] Outputting from $_POST

[Omzy]

I have a form which captures customer's details, such as Name, Address, Date of Birth, etc, and then displays them back to the user (and sends me an email with the details) upon submission, as follows:

 

foreach($_POST as $key => $value)
{
echo "$key : $value";
}

 

This works fine for me, but I have now split up the Date of Birth field into 3 seperate fields - Day, Month, Year. But I still want it to be output as one field (Date of Birth) at the end.

 

Because I'm outputting $_POST this is proving to be difficult. Can anyone help?

Just combine them into a single index before looping and remove the other ones. For cleanliness, create a copy of $_POST for this purpose so you don't pollute it.

Cheers Daniel0, I've tried using array_push to add the combined value to the end of the array, but it doesn't seem to work:

 

array_push($_POST['DOB'],"".$_POST['Day']."-".$_POST['Month']."-".$_POST['Year']."");

[Daniel0]

Well, that's not how array_push() works.

 

What you're looking for is:

$_POST['DOB'] = $_POST['Day']."-".$_POST['Month']."-".$_POST['Year'];

Ah wicked, that's worked! So now can you tell me how I can remove those redundant keys/values from $_POST?
