Perch_content_custom 'page'

I have some [master pages] set up, and I want to use perch_content_custom to change the background of a section depending on it's folder.

Cattle Folder index.php - [course-category.php] (includes original perch_content which sets the background image for this category) cattle-course.php - [course.php] (uses perch_content_custom to get it's backgorund)

Sheep Folder exactly as above in cattle folder

However I have to refer to the 'page' starting at the root of the site. I have tried just putting in index.php as the page url which results in php not outputting anything. Is there a clever way to select index.php in the same folder as the current page?

Thanks

I don't really follow. Can you show us the code that isn't working, along with what result you're getting and what result you're hoping for?

Sure:

From course-category.php

<section class="courses" style="<?php perch_content('Course Navigation Background Image'); ?>">
    <?php 
    perch_pages_navigation(array(
        'from-path'=>'*',
        'from-level'=>2,
        'template' => 'course-grid.html'     
    )); ?>
</section>

And referring to that file is course-single.php

<section class="courses" style="<?php perch_content_custom('Course Navigation Background Image', array('page' => '*', 'template' => 'course-image.html') ); ?>">
    <?php 
    perch_pages_navigation(array(
        'from-path'=>'*',
        'from-level'=>2,
        'template' => 'course-grid.html'     
    )); ?>
</section>

Currently where the '*' is I would like to refer to the index.php in the same folder as the current page.

Probably the easiest way is to get the current page path, explode it on a forward slash, drop the last item from the array, then append index.php and implode it on a forward slash again.

After looking around the internet thanks to your explanation I have found:

To get the current page path i found here:

http://stackoverflow.com/questions/6768793/get-the-full-url-in-php

$current_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

Explode that:

http://board.phpbuilder.com/showthread.php?10380358-RESOLVED-explode-is-causing-problems

$link_array = explode("/", $current_link); 

Take a look at the output using var_dump:

http://www.php.net/manual/en/function.var-dump.php

var_dump ($link_array);

Pop the last item off, then append 'index.php':

http://www.php.net/manual/en/function.array-pop.php

http://stackoverflow.com/questions/6797641/php-how-to-add-to-end-of-array

$remove_last_item = array_pop($link_array);
$link_array []= 'index.php';

Implode the array:

$url = implode("/", $link_array );
echo $url;

outputs: /courses/cattle/index.php

However, I can't get this next part to work:

style="<?php perch_content_custom('Course Navigation Background Image', array('page' => $url, 'template' => 'course-image.html') ); ?>"

Thanks, Adam

The reason is probably that the variable $url outputs /courses/cattle/index.php

however what I need to output is:

'/courses/cattle/index.php'

Manage to wrap the variable in quotes but perch_content_custom still doesn't work:

<?php 
    $current_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
    $link_array = explode("/", $current_link); 
    array_pop($link_array); 
    $link_array []= 'index.php';
    $url = implode("/", $link_array );
    $quote = "'";
    $echourl = $quote . $url . $quote;
?>

which outputs '/courses/cattle/index.php'

style="<?php perch_content_custom('Course Navigation Background Image', 
                array(
                'page' => $echourl, 
                'template' => 'course-image.html'
                    ) ); ?>"

by the way course-image.html outputs a css background style. It works elsewhere in the site.

Perch doesn't care about the domain name - just the path from the root of the site. Don't use the domain or protocol.

That's what I am doing, aren't I?

'/courses/cattle/index.php'

It seems that giving perch_content_custom a straight url to the page works, however a variable with exactly the same content as the url will not work.

This works

<?php perch_content_custom('Course Navigation Background Image', 
                array(
                'page' => 'courses/cattle/index.php', 
                'template' => 'course-image.html'
                    ) ); ?>

This doesn't work

<?php perch_content_custom('Course Navigation Background Image', 
                array(
                'page' => $taggedurl, 
                'template' => 'course-image.html'
                    ) ); ?>

Make sure the path starts with a slash - the top instance shouldn't actually work!

Sorry, it actually does work - that was a typo.

$echourl = '/courses/cattle/index.php'

like I said, typing in the url in quotes works fine, putting in the $echourl variable doesn't.

Thanks for all your help so far.

I don't understand why you're adding the quotes to the string. The path doesn't contain quotes.

To clarify, when using perch_content_custom, if a url is referenced it is normally put in quotes as standard. When obtaining the url dynamically in a variable using this method, it outputs without quotes.

I still haven't managed to get this working.

Quotes are used to denote a string. If you have a string, you don't put quotes into it.
