I've got this code in my prestashop template, there is no loop, only conditional, and I get 5 back buttons (elseif section, first li tag), why is it happen?
{if $node.children|#count > 0 && ($smarty.get.controller!='product' && $smarty.get.controller!='category')}
<li class = "li-parent">
<asset class="menu-arrow-left"></asset>
<p><span>{$node.name|escape:'htmlall':'UTF-8'}</span></p>
{elseif $node.children|#count > 0 && ($smarty.get.controller=='product' || $smarty.get.controller=='category')}
<li class="li-back"><asset class="menu-arrow-right"></asset><p class="class="border-bottom-grandiet-small"><span>Back</span></p></li>
<li class = "li-parent">
<p><span>{$node.children[0].name|escape:'htmlall':'UTF-8'}</span></p>
{/if}
I don't see anything in this code that could cause displaying 5 back buttons. I suspect this code is included in some kind of loop and that's why it's displayed 5 times.
You should change the whole above code with:
testonly
and then look at page or page source and check how many testonly texts will appear.
It's also possible if you really use loop that you should use some extra condition. For example instead of:
<li class="li-back"><asset class="menu-arrow-right"></asset><p class="class="border-bottom-grandiet-small"><span>Back</span></p></li>
you should use
{if $node.children|#iteration eq 1}
<li class="li-back"><asset class="menu-arrow-right"></asset><p class="class="border-bottom-grandiet-small"><span>Back</span></p></li>
{/if}
and probably the rest should be more similar to the first condition so instead of:
<li class = "li-parent">
<p><span>{$node.children[0].name|escape:'htmlall':'UTF-8'}</span></p>
you should use:
<li class = "li-parent">
<p><span>{$node.name|escape:'htmlall':'UTF-8'}</span></p>
but it's really hard to say if we don't know what's the data structure and what exactly you want to achieve. If it still doesn't work you should provide more details to your question, explain what you want to achieve, what data you have in your variables and so on.

I've got a foreach loop running on my site to display images. There are some images I do not wish to display however so I added an if statement to exclude these images. The problem though is that using the if statement within the loop means that I can't use $smarty.foreach.thumbnails.last to work out which image is last as it could be one of the hidden ones.
How would I go about filtering these images and still being able to use $smarty.foreach.thumbnails.last?
Here is my code as it stands:
{foreach from=$images item=image name=thumbnails}
{if $image.legend != "colorschemes"}
{assign var=imageIds value="`$product->id`-`$image.id_image`"}
<li data-imgtype="{$image.legend}" class="items{if $j == 1} main-pos{elseif $j == 2} right-pos{elseif $smarty.foreach.thumbnails.last} left-pos{else} back-pos{/if}" id="{$j}">
<img src="{$link->getImageLink($product->link_rewrite, $imageIds, 'tm_large_default')|escape:'html':'UTF-8'}" alt="Owl Image" style="width:100%; margin-top:-200px;" />
</li>
{$j = $j + 1}
{/if}
{/foreach}
One solution would be to filter the array in the back end before sending it to the template. This could potentially have better performance as the client won't be loading unnecessary images. The filtering could be done in php or sql.
I've been playing around with golang for a couple of weeks now, and recently started to look into the revel framework.
In other languages/frameworks that I've used, it's always been possible to check what the current route is from within the template. Something that made it easier for me to keep things like navigation in a separate template file, and just do this:
<!-- in header template -->
<ul class="nav">
{{ if eq .req.action "App.Index" }}
<li class="active"><a href="#">
{{ else }}
<li><a href="{{url "App.Index" }}">
{{end}}
Home</a></li>
<!-- other links here -->
</ul>
This isn't the actual code I'm writing, but I hope this makes it clear what the idea is: Have a template for the navigation handy, and set classes/links according to which action is the current one.
After some time going through the source code, and a number of golang template examples, I couldn't quite see any way in which the current action or anything else is exposed to the template.
To get around this, I'm currently using a func interceptor which automatically sets a render argument for me:
func prependRoute(c *revel.Controller) revel.Result {
c.RenderArgs["_current_route"] = c.Action
return nil
}
This is working fine, but it feels a bit hacky. I think I'm probably missing something really obvious that would allow me to reserve func interceptors for when I really need them.
The question, then, is simple: What is the correct, and most reliable way to find out what the current action is in a revel template?
I am building a site in Expression Engine with a hard-coded navigation. I need to hide one of the nav items until the client makes an entry under a certain category, here's what I have right now:
{exp:channel:entries category_name="name" limit="1"}
{if count > 0}
<li> • Link</li>
{if:else}
(don't show anything)
{/if}
{/exp:channel:entries}
Any thoughts? Thanks!
yeah, exactly. If there is nothing there, it just won't show anything. If you needed to add a placeholder or something, you could use the {if no_results} tag.
I have a problem with outputting categories in to a list.
It seems to create another ul(one for the channel:categories) within the my ul, and also creates empty lists before each list.
I used the exact same code for entries and it worked fine.
Is this a categories problem?
Here is the Code:
<ul>
<li><a {if segment_2 == ""} class="selected" {/if} href="">News & Events</a></li>
{exp:channel:categories
channel="news_events"
disable="pagination|member_data|trackbacks"
dynamic="no"}
<li>{category_name}</li>
{/exp:channel:categories}
<li><a {if segment_2 == "gallery"} class="selected"{/if} href="">Image Gallery</a></li>
Any help would be appreciated!
With regard to the code output, take a look at the style parameter for the channel categories tag: http://ellislab.com/expressionengine/user-guide/modules/channel/categories.html#channel-categories-style. You'll want to change it to style="linear" to use your own markup.
As for the blank output, it's going to be tough to diagnose without seeing your install but try getting rid of dynamic="no".

Ignore these DOM guys. They don’t know what they’re talking about, and even if they do, they haven’t answered your question, which is rude.
If that’s really all you’re trying to do, which I believe is strip tags and leave the rest, you can strip those particular tags up there that don’t contain fancy stuff with a simple:
s/<.*?>//g;
and you’ll have to convert the entities like
s/ //g
On arbitrary HTML, you have to be a lot more careful than this of course, because you have <script> tags and <style> tags and CDATA sections and alt=">" and all that jazz, but on the sample you presented, this will work just fine.
Don’t you have better ways of converting HTML to text than this, though?
Do not use regex for this kind of stuff (i think that you don't use hammer instead of the wrench when you need to screw a bolt?), use special tools that are used for this kind of operations : HTML DOM parser (http://simplehtmldom.sourceforge.net/) or something similar.
