[PHP] Shopping with variables

2001-05-16 Thread Tarrant Costelloe 

I am currently just messing around with a basic shopping cart, but have
stumbled onto a problem.
Bascially there is three input boxes all name DVD, VIDEO, CD and these are
also variables. Once the user has said they wanted 15 cd's for example,
the form then takes them onto the shop.php. Which say's something along the
lines of:

?php print( You have asked to purchase $dvd $video $cd 's - Thank you) ?

This prints out, You have bought 16 - Thank you for example, see the
problem? How do I get it to print the variable name not just it's value?

Try with replacing your print with the following one:

print( You have asked to purchase DVD: $dvd VIDEO: $video CD: $cd 's - ...

it should work.

TC This prints out, You have bought 16 - Thank you for example, see the
TC problem? How do I get it to print the variable name not just it's value?

Use

?php print( You have asked to purchase .
  ($dvd ? DVD: $dvd :'').
  ($video ? Video: $video :'').
  ($cd ? CD's: $cd :'').
   - Thank you) ?

 Thanks Gabriele :) Whilst waiting for your e-mail I figured out another
 way...Thought I would show you it just in case you ever find the 
 need to use
 this alternative:
 
 ?php print( You have asked to purchase .
   ($dvd ? DVD: $dvd :'').
   ($video ? Video: $video :'').
   ($cd ? CD's: $cd :'').
- Thank you) ?
 
 Best Regards
 
 Taz


This should work even better.

Ciao

Gabriele

Might want to reconsider the way you are doing this, since this may not be
the most efficient way. An alternative might be to do this as follows:

In your web form set a field for Quantity and another for Item Name, so for
example:

FORM ACTION=script_name.php METHOD=post

...

Quantity: INPUT TYPE=text NAME=item_qty SIZE=2

SELECT NAME=item_type
OPTION VALUE=DVDDVD/OPTION
OPTION VALUE=VIDEOVIDEO/OPTION
OPTION VALUE=CDCD/OPTION
/SELECT

...

/FORM

then when you process the form all you would have to do to display your
thank you message:

print You have asked to purchase $item_qty $item_type. Thank You;

Nevertheless, if for some reason you must do things like you are doing them
now, try something like this:

if(isset($dvd)){
   $item_type = DVD(s);
   $item_qty = $dvd;
}

if(isset($video)){
   $item_type = VIDEO(s);
   $item_qty = $video;
}

if(isset($cd)){
   $item_type = CD(s);
   $item_qty = $cd;
}

print You have asked to purchase $item_qty $item_name;

Keep in mind that this is not the most efficient method since it will
require that you continue adding if(isset($variable)) statements, if you
ever decide to add more item types.

 That will work, assuming the user is not allowed to purchase multiple
items...

RE: [PHP] Shopping with variables

2001-05-16 Thread scott [gts] 

why not use serialized arrays stored in cookies to 
store a growing list of things that the user is purchasing?

then, it'd be as easy as having this array
stored as a single cookie... ;)

$items = array(
#indexed by item ID
'1003045' = array(
'name'  ='The best movie',
'type'='DVD',
'quan'=1,
),

);


then you could loop thru the array and have
all the information right at your fingertips

print You ordered $items[$current]['quan'] of $items[$current]['type'];
