Right, Jon, you've lost me now...

(By the way, after I implemented your suggestions, I noticed that if I clicked on the ALL option, I simply received a blank page in my browser (change_ppp.php). Clicking on the other options worked fine.)

Re: Let Customer choose number of products displayed on page

Pretty slick! I've been thinking about adding "Products Per Page" to the category modify template so the cart can be configured at the category level for page length. Don't suppose anybody's already done that?

Re: Let Customer choose number of products displayed on page

I don't want to hijack this thread as it's a good mod... and not my mod... but I've had to assist several store owners who have had the misfortune of having their sites hacked due to varying exploits, so please excuse my paranoia and hesitation to rely on x-cart's data sanitizing :)

Here's the code I would use in change_ppp.php:

Code:

<?php

if ( !defined('XCART_SESSION_START') && ($_SERVER['REQUEST_METHOD'] != "POST")) { header("Location: home.php");}

require_once "auth.php";

x_session_register("products_per_page");

if ($_SERVER['REQUEST_METHOD'] == "POST") {

 if ($ppp) {

  $back = $_SERVER['HTTP_REFERER'];

  if (!$back)

   $back = "/home.php";

  if ($ppp == "all") {

   $ppp = 32767;

  } else {

   $products_per_page = (int)$ppp;

  }

  x_session_save("products_per_page");

  func_header_location($back);

 }

}

if ((int)$products_per_page > 0) {

 $config["Appearance"]["products_per_page"] = $products_per_page;

 $objects_per_page = $config["Appearance"]["products_per_page"];

}

$smarty -> assign("products_per_page",$config["Appearance"]["products_per_page"]);

?>

Re: Let Customer choose number of products displayed on page

I appreciate that thanks Jon that code seems to work fine, including the show ALL...

Re: Let Customer choose number of products displayed on page

Thank you, Jon, for this corrections. Of course, somebody could read this thread and use opened code to find a security hole. Anyway thanks Jon.

Re: Let Customer choose number of products displayed on page

Has anyone encountered problems with this working in HTML Catalog mode? Can't seem to make it work there, only in dynamic mode

Re: Let Customer choose number of products displayed on page

Excellent post and exactly something I needed...except for one thing -> the onchange in the form provided in post #2 gave this error: "document.product_per_page_form has no properties"

So instead of
onchange="javascript: document.product_per_page_form.submit();"
I used
onchange="this.form.submit()"
which fixes the problem

I then stripped out the unnecessary name attribute in the form tag and the all option (since that would have been overkill for me), and added an id so I could apply styles:

Code:

<form method="POST" action="/change_ppp.php" id="pppForm">

    Show products per page

    <select name="ppp" onchange="this.form.submit()">

    <option value="12" {if $products_per_page eq 10}selected{/if}>12</option>

    <option value="20" {if $products_per_page eq 20}selected{/if}>20</option>

    <option value="30" {if $products_per_page eq 30}selected{/if}>30</option>

    <option value="50" {if $products_per_page eq 50}selected{/if}>50</option>

    <option value="75" {if $products_per_page eq 75}selected{/if}>75</option>

    <option value="100" {if $products_per_page eq 100}selected{/if}>100</option>

    </select>

</form>

I successfully tested it in PC Firefox & IE7, Mac Firefox & Safari. You can see it in action here: http://www.shopbettylin.com/home.php?cat=249

Re: Let Customer choose number of products displayed on page

Yes, you right about this modification.

Re: Let Customer choose number of products displayed on page

Works great...thanks for the great contribution Antony and I appreciate the concern for security Jon.

Re: Let Customer choose number of products displayed on page

Very useful mod, but I guess it's only for 4.1.x and not for 4.0.x?
Because changing the number of products brings me straight away to home.php...

Anybody a idea what to change so it will also work with 4.0.x?
I really could use this mod in our store...

Thanks! :-):-):-)
