[Solved] show slideshow only on home page

sixthmind · February 22, 2012

I have hardcoded jquery slideshow into header.tpl and now I am having some problems with displaying it where I want it to be displayed.

I put this code before the slider:

{if $page_name = 'index'}

and after slider

{/if}

The results of this are mixed. The slider is displayed on home page but it's also displayed on inner pages (categories pages and cms pages) only that is broken (no jquery called).

What code could I use to display slider only on home page? Your help would be really appreciated.

sixthmind · February 23, 2012

I have now found free Slideshow module and the slideshow shows only on home page: http://www.custommodule.com/prestashop/prestashop-module/prestashop-slideshow-module

But I still need to know what is the correct code for checking if we are on home page. Anybody?

sixthmind · February 24, 2012

it seems that {if $page_name = 'index'} should be {if $page_name == 'index'}.

dhada · February 24, 2012

{if $page_name == 'index'} yes this is the correct

radhouaneraafet, the reason why your slider is appearing only on home page is because it's hooked on home hook, which is of course only for home page. you need to hook it to other relevant hook, which is on all other pages. you may need to create your own.

Prince Raafet · May 15, 2012

thank you, i solved my problem before you answer me , but thank you again, i created as you told me a new hook and installed it there, but how had was that to do, first hack/change the code of the module, second insert the hook name in the database ,third insert the hook command in "FrontController.php" that was in /controllers/ folder... .

here is the final site link : http://ares-reseau.net/boutique/shope/fr/ .

thank u again, happy to meet you

Hello,

Thank you for your posts, very useful!

I have a similar problem now:

I would like to show a module only on a category page: do you know I can I do?

Thank you!

Thank you!

go to modules > positions click on edit button near this module (in each of list)

then define exceptions, select all pages instead "category"

Grafeco · October 30, 2013

Easier:

modules/homeslider/homeslider.tpl

include:

{if $page_name == 'index'}

and:

{/if}

result:

{if $page_name == 'index'}

    {if isset($homeslider_slides)}
    <ul id="homeslider">
    {foreach from=$homeslider_slides item=slide}
        {if $slide.active}
            <li>
                <a href="{$slide.url|escape:'htmlall':'UTF-8'}" title="{$slide.description|escape:'htmlall':'UTF-8'}">
                <img src="{$smarty.const._MODULE_DIR_}homeslider/images/{$slide.image|escape:'htmlall':'UTF-8'}" alt="{$slide.legend|escape:'htmlall':'UTF-8'}" height="{$homeslider.height|intval}" width="{$homeslider.width|intval}" />
                </a>
            </li>
        {/if}
    {/foreach}
    </ul>
    {/if}


{/if}

Vekia: I do not have exactly that problem...

I mean: I would like to show a module only on a particular category page, not on all the categories pages.

Can you help?

Tanks!

vekia · October 31, 2013

you can do it with if conditions but in this case you will need to modify module files.

{if isset($smarty.get.id_cat)}

{if $smarty.get.id_cat==6}

SLIDER CONTENTS HERE

{/if}

this code will show slider only on category id = 6

Hi all,

I want to achieve a similar thing with the blockcategories module - I want the module to only display on certain category pages (I'm using layered navigation for other categories).

I tried using the above code on blockcategories.tpl but it doesn't work, the module doesn't appear on any categories.

Any ideas?

PS 1.5.6.2

vekia · February 12, 2014

have you defined correct id of category (id_cat) where you want to display this block?

pel024 · February 12, 2014

I found the solution:

{if $smarty.get.id_category == 15 OR $smarty.get.id_category == 17 OR $smarty.get.id_category == 20}

//Module code//

{/if}

Obviously changing the category id's to the ones you want the module to appear.
