for 1. Have you also set the ones in /wire/ also to 444?

Thanks for the suggestion. I have tried that. I still get the same errors.

I cannot say what is causing your first issue, since if those files really are 0444, then you shouldn't see those warnings. The second one: check your parent page template settings: children -> Required Template for Children. You should have "Any" set there, now you might have some template (other than "page") set there, which only allows that template.

PS: I'm not sure but it might be good to have another setting for default template for children? I know that pw is pretty good guessing what template you want (based on the other children pages), but it's not always right.

That setting is what I missed. Thanks again.

Hi,

I'm getting a few errors and I'm not sure what might be causing it.

First, I get:

Security Warning: /site/config.php is writable and ideally should not be.
Security Warning: /site/index.php is writable and ideally should not be.

Both files are set to 444.

The second is when I try to change the template used by a page.

 Template 'page' is not allowed

'page' being my template name. The page has no content.

Sir, you are a gentleman. Thank you. I would not have worked that out.

Thanks for you help and time. It's nearly there except for when I'm on the main Advertising 'list' page. I'm a php ubernoob and I don't understand that code enough. In EE or textpattern this kind of navigation highlighting would take me 2 seconds (with sections and url_segments). I think I'll just hard code it and write a load of CSS. Thanks again.

Thanks for the replies. I think I should illustrate more clearly what I'm trying to do.

Here's the development site: http://otoshpw.clientsite.net.au/

My pages are structured thusly:

Home

-Illustration

--Advertising

---client_work_item

---client_work_item

---client_work_item

---client_work_item

-Art

--Limited Edition Prints

etc, etc

I'm not including Home in the navigation I'm generating. What I'd like to do, for example, is whenever I'm in a section/page like Advertising or any page under that, have class='current' apply to that LI.

Regards

Martin

I spoke too soon. That won't highlight if I go down another level.

Ahhhh. Thank you!

Hi,

I'm using the code below to generate a basic navigation:

<?php 
foreach($pages->find("parent=/illustration, sort=sort") as $p)
{
echo "<li><a href='{$p->url}'>{$p->title}</a></li>";
}

Works great but I'm trying to work out how to add a class="current" to the LI if that page matches that nav item - and at any level. I've had a go at trying to work out the code in the sitemap template but without any luck.

<?php
$nav = $pages->get("/illustration"); 
$children = $nav->children;

foreach($children as $child) {
	$current = $child === $page->rootParent ? " class='current'" : '';
	echo "<li$current><a href='{$child->url}'>{$child->title}</a></li>";
}

Any thoughts?

Regards

Martin

Hi Ryan,

It's in a template called artist_list. My pages are:

Portfolio - uses template artist_list.php

- artwork - child page uses template 'artist_work' with two fields - artist_image & artist_thumbnail

- artwork - etc

- artwork - etc

All I'd like to do is generate a thumbnail from the larger image if the thumbnail image isn't present. The child pages won't be viewed as such as I'm calling the larger image into Fancybox.

Hi Ryan,

I have both fields set to 1 as each will hold a single image.

'artist_image' holds the full size image

'artist_thumbnail' holds the thumbnail

...both are set to 1. Perhaps I'm doing something else wrong.

No problems. I really appreciate all the help you've given me.

Thank you again. Your explanation goes some way in helping me learn PW better and I appreciated it.

If I don't upload a thumbnail and get PW to generate a thumb I get the below error.

Call to a member function size() on a non-object 

<?php
foreach($page->children as $artist_item) {
    $image = $artist_item->artist_image;
    $thumb = $artist_item->artist_thumbnail; 
    if(!$thumb) $thumb = $image;
    $thumb = $thumb->eq(0)->size(100,100);
    echo "<li><a rel='lightbox' title='{$artist_item->title}' href='{$image->url}'><img src='{$thumb->url}' alt='{$artist_item->title}'></a></li>";
}

That's done it! Thank you!

If I remove this line:

$thumb = $thumb->size(100, 100);

the page renders with the link to the full size image - which is what I'm after.

Yes I have. http://awesomescreenshot.com/0a6ar6qac

Hi,

Thanks for your help. I've started from scratch. I have two fields, artist_image & artist_thumbnail. I get the same errors.

<?php
foreach($page->children as $artist_item) {
    $image = $artist_item->artist_image;
    $thumb = $artist_item->artist_thumbnail; 
    if(!$thumb) $thumb = $image;
    $thumb = $thumb->size(100, 100);
    echo "<li><a rel='lightbox' title='{$artist_item->title}' href='{$image->url}'><img src='{$thumb->url}' alt='{$artist_item->title}'></a></li>";
}

Thanks Ryan,

I get all sorts of errors if I try that code.

Hi,

I'm trying to get my head around something I know should be simple. I'm working on an a site for an artist who'd like to upload a custom thumbnail for each of his images. I've added a second field called 'artist_thumbnail'. In my template I want to test to see if there's a custom thumbnail and if not get processwire to generate one automatically.

PHP isn't my strong point. Am I even close with this code?

foreach($page->children("limit=32") as $folio_item) {

if($folio_item->artist_thumbnail) {
        $img = "<li><a rel='lightbox' title='{$folio_item->title}' href='{$image->url}'><img title='{$folio_item->title}' src='{$thumb->url}' alt='{$folio_item->title}'></a></li>";
} else if($folio_item->artist_image) {
        $thumb = $folio_item->artist_image->size(100, 100);
        $image = $folio_item->artist_image;
        $img = "<li><a rel='lightbox' title='{$folio_item->title}' href='{$image->url}'><img title='{$folio_item->title}' src='{$thumb->url}' alt='{$folio_item->title}'></a></li>";
    } 
// Output the image
echo "$img";
}

I think I have it sorted.

if($page->prev->id) {echo "<p class='next'><a href='{$page->prev->url}'>prev</a></p>";}
if($page->next->id) {echo "<p class='prev'><a href='{$page->next->url}'>next</a></p>";}

Hi Ryan,

This would be a great feature to have. If only to keep duplicate images to a minimum.

Regards

Martin

Thanks again Ryan.

Another noob PHP question. Can I use a conditional to check whether I'm on a first or last page? That way it only outputs 'next page' or 'previous page' if there actually is one.

Regards

Martin

Hi,

Am I right is assuming that an uploaded image is only available to that specific page and not any other pages via the admin?

Regards

Martin

Hi everyone,

Ryan, that's exactly what I meant.

Jim, actually I'm thinking Martin's talking about the next/previous sibling, rather than pagination. Though reading it again, now I'm not sure. Martin, can you confirm? Either way, I do need to add those next/prev sibling API functions.

Hi,

This is my first post here and I'm a bit of a php noob - but willing to learn nonetheless. I really like approach of this CMS. I think it'd be a fantastic offering to a lot of my clients.

My first question (probably of many) is regarding next/previous page linking. I'm picking through the demo site code and say, for example I'm on the About Us > Child page example 1. How would I go about adding a next / previous page link that works only on that level?

Thanks & regards

Martin
