check for 'continue shopping' button pressed

how do i check for 'continue shopping' being pressed on the cart page.

I have a results page, on which i want to check for continue shopping being posted.

i have tried if(isset($_POST["cscart_Contiune_100"]))

that if statement should work unless it is an image button, then the code should be:
if(isset($_POST["cscart_Contiune_100_x"]))

Hi Jason, no its not an image.

then this:
if(isset($_POST["cscart_Contiune_100"]))

is the correct code.

if this is not working i need more details to go on.

a copy of the page would help and an explanation of what you are trying to accomplish

OK, here is the attached file

the client does not want the results page to be displayed on page load, so i am checking for the form to be posted before the results are displayed. (around line 1104)

However there are 2 other instances when I want the results displayed.

1, if items have been added to the cart and continue shopping has been pressed, when this page reloads, I want the results (and the existing search criteria) to be displayed.

2. if the customer forgets to check a row and clicks add to cart, the server validation reloads the page , highlighting the error, and the results are still displayed

OK, well, the continue shopping button on the cart page does not post to the results page.

when the add to cart button is pressed, the page that contains the add to cart button is stored in a session

On the cart page, the continue shopping button triggers a behavior to go back to the last page that an add to cart button was used on.

there is no way ion the results page to know if the continue shopping was pressed. you can check for the cart not being empty, but you cannot check for the continue shopping button pressed on the results page.

OK, thanks for looking, I'll try and think of a workaround.

This prompts my second question.

Before I added the server validation, I checked for the add to cart 'submit' being pressesed, and this allowed me to display the results.

After adding the server validation, if the validation fails, and the page is reloaded, however, in this instance, the 'submit' has not just been posted, so the results are not displayed.

set the server validation failure redirect to pass a querstring back to the results page:
results.php?failed=true


and use the failed querystring to trigger showing the results.

Great, that works.

The only thing is, if i persist in clicking the add to cart without selecting anything, the querystring builds up, am i doing it right ?

eg

results.php?failed=true

can become

results.php?failed=true&failed=true&failed=true&failed=true

that's because the forms action is set to pass any existing QS varaible on submit.

add the following code just before the form tag to clear it from the QS:

php:
<?php

if(isset($_SERVER["QUERY_STRING"])) {
    
$arrQS explode("&"$_SERVER["QUERY_STRING"]);
    foreach(
$arrQS as $k => $v) {
        if(
$v == "failed=true ") unset($arrQS[$k]);
    }
    
$_SERVER["QUERY_STRING"] = implode("&"$arrQS);
}
?>
