string inside a function?

[ryanhellyer]

I'm trying to manipulate WordPress's wp_list_pages function for my dropdown menu plugin.

The following code, will generate a complete list of pages in your WordPress install, minus page number 262

PHP Code:

<ul>
    <?php wp_list_pages('exclude=262' ); ?>
</ul>

I want to allow users of my plugin to remove pages from their list via the admin panel. To do this, I first considered creating a string which contains the page number they want to exclude (eg: 262) and inserting that into the function like so:

PHP Code:

<ul>
    <?php
    wp_list_pages('exclude=$whatever' ); ?>
</ul>

However when I tried this, it simply ignored the string.

Any ideas on how to get around this problem? It is a feature many of my plugins users would like but I haven't yet figured out how to implement it.

Thanks

Well I had a look at the WP documentation here, and you seem to be doing it right. Are you sure the variable contains just a number, and that it corresponds to a page?

[ryanhellyer]

The documentation doesn't say anything about using strings within the function though.

In case you are confused about which part of the code I'm talking about, I'll highlight it below:

<ul>
<?php
wp_list_pages('exclude=$whatever' ); ?>
</ul>

Ah, well that would be a variable not a string
I think the problem is that you're using single quotes instead of double quotes - with singles, variables inside are not replaced with their value. You can either change to double quotes, or if this isn't convenient in the cotext of the surrounding code, just use concatenation like below:

wp_list_pages('exclude=' . $whatever);

BINGO!

That did the trick A new version of my dropdown plugin will be released shortly with the option to exclude certain pages and categories from the dropdown

BigAlReturns - I'd like to add a credit to you in my plugin. What URL should I link to? And would you prefer your real name or just "BigAlReturns"?

[ryanhellyer]

And my code is done

BigAl, I've added a credit to you in the plugin itself and on the beta page of my plugin ... WordPress Dropdown Menu Plugin Version 1.9.0 Beta | Ryan Hellyer’s Website

Once it comes out of beta, you get a link on the main plugin page and in the WordPress plugins repository.

I've used your blog for the link and your internet handle as your name at this stage, but I can change that later if you prefer.
