splash or "please wait" until page load

[drumhrd]

Hello all,

 

I am building my own shopping cart, attempting to use paypals DoDirectPayment which seems to work fine.

 

What I need is a splash page or "please wait" status image.

 

I have my payment form on page A and my processing page on page B.  page B doesn't load until the response back from paypal is finished and the server sends the generated code.

 

I would like to be able to display a "processing please wait" or something of the sort on my page B until I get the response back from paypal.

 

I've tried sleep() funcitons or ob_start()...but couldn't get those to work so trashed the code.

how long does it take for you receive this response from paypal?  i've worked with paypal a ton, and IPN responses from their servers take milliseconds.  hardly enough time to shove a "please wait" message down the users throat.

 

anyways, you could just use javascript with a hidden div tag and onclick to display a message when the user clicks the payment button or whatever.  pretty simple.

Right now I am not worried about IPN.  I am using DoDirectPayment, which in my testing agaist the sandbox site, has taken up to 2 minutes for a response.  In the meantime, the page just sits on the form page..once the reponse is recieved, the response page loads.  I do not like that affect.  I would like to show a Please wait message with an animated status GIF to show the user the page is actually doing something.

[mrMarcus]

i would recommend getting that 2 minutes eliminated, 'cause no animated .gif in the world is going to keep me entertained for that long.  your users are going to close the page after 30-60 seconds, let alone 2 minutes.

 

why don't you ask Paypal why it takes so long for the processing.  see if that's normal first, then worry about entertaining your users with redundant animations.

 

just my opinion.

 

you can also take heed to what i already suggested with the following:

TCPDUMP confirmed paypal is taking 30+ seconds to fully respond

 

I see alot of initial info being passed, then a 30+ second pause before I get a final PUSH/ACK from paypal, then the connection closes.

 

I am using a some cURL functions to execute this..maybe I am doing something wrong?  Maybe I am not closing the connection properly or something.  unforturnately, the Paypal API is only available via SSL so I cannot cURL clear text so I can decode the packets with wireshark to see what's going on.
