OMG Please help me im going insane!!!

I have posted about this before but the more i think im understanding the more im getting confused

I think im going to put my head through the wall soon

What i want to do seems so simple but i just dont have the php knowledge to do it

I have an enquiry form on my rentals website .... the customer ticks what they are interested in i.e tv’s or fridges
then clicks submit enquiry and i call them on the phone number they supply this is easy for me to do.

What i would prefer ... and what i have been trying to do is have a button on each of my product pages such as
the Television Page that says [ADD TO ENQUIRY] which they click and then continue to browse on to another page
and repeat the process ...

its kind of like a cart but without actual products what i was hopeing to do was use the
[*page_title*] placeholder as the product name as the pages are already called Televisions, Fridges, ECT ....

So when they click the [ADD TO ENQUIRY] button it just remembers the page name "somewhere" (not in the database! but maybe in this mystical php session that i just dont understand ... ) and then once they are ready they could click [PLACE YOUR ENQUIRY] and they would be sent to a form which already knows what items they wish to enquire about and then they only need to put in name and phone number and hit [SUBMIT]

Now some helpful people have given me some one line answers like just store it in a php session but i dont understand
if anyone would be kind enough to give me a simple but more detailed explanation:

Including how do i add to the session variable? do i use a form? php snippet? HELLLLPPPPPPP

i would be VERY VERY Greatfull for any help

Okay i think ive figured it out but just a nother little quick question

when i place this code into a snippet:



it returns the following error:

« MODx Parse Error »
MODx encountered the following error while attempting to parse the requested resource:
« PHP Parse Error »

Is the session variable an array? It needs to be to do it that way.

Is it set? you can check with:



You should always check to make sure there’s something to process before working with it:

BTW, here’s another way to go. You could make the $_SESSION variable a comma-delimited string (e.g. ’tvs,vcrs,toasters’). I think it might be easier to understand than updating an array:

On submit, you’d do this (assuming that $pt is set to the pagetitle):
