add hidden strings to $_posts

rpx

I have on my website a form, with the following text fields,

Name, Address ,etc.

I want to be able to add text, along with the post variable, but keep it hidden.

So if they type, "103-33 77 St" in the address text field, I want to secretly add a city "New York" to the $_POST variable, without they being able to see it, or them having to type it.

<input type="address" name="address" maxlength="30" value="<?php echo $_POST['address']; ?>" />

I hope this make senses to someone :queasy:

Instead, why don't you have a hidden field and then concatenate them when processing the form:

<input type="text" name="address" maxlength="30" value="<?php echo $_POST['address']; ?>" />
<input type="hidden" name="city" value="New York" />

Edit: Unless of course you don't know the city, in which case you'd have to do some ajax to guess which one it is. But if you're doing that, you'd might as well just take care of it server side anyway. But it would probably help if you explained what you're trying to do.

Yep, I do know the city, its just one.

Question about concatenating,

Would I do something like,

$city = "New York";

$_POST['address' . $city]

$_POST['address'] [$city]

dagon

neither

either

$_POST['address'] .=$city

//or 

$_POST['address'] = $_POST['address'].$city

although at a guess you are going to want to add space in there

$_POST['address'].=' '.$city;

Yeah, $_POST['address' . $city] would mean that your form field was the address concatenated with the value of $city. ie <input type="text" name="'123 Some St.New York" />

$_POST['address'] [$city] is a multidimensional array. Neither of which is what you want.

Actually, it would be more like:

 <input type="text" name="addressNew York" />

Whoops, yeah.
