@schrotty, the escaping will be fixed in the next version.

Hi @morantivo,

You cannot use multiple taxonomies with the short-code. This will require the PHP method in an appropriate template in your theme. You will want to use the_a_z_listing() function and a parameter array the same as WP_Query accepts:

the_a_z_query( array(
    'post_type' => 'growing',
    'tax_query' => array(
        array(
            'taxonomy' => 'flower',
            'field' => 'slug',
            'terms' => 'yellow',
        ),
        array(
            'taxonomy' => 'season',
            'field' => 'slug',
            'terms' => 'autumn',
        ),
    ),
) );

Your PHP code looks correct. I’m not sure what would be going wrong with it.

It is possible to modify the SQL for a posts listing by hooking the available WP_Query injection points, as this plugin uses WP_Query for posts listings. For Taxonomy term listings we use the function from core called get_terms() so if there are any SQL hooks in that then you can inject there, but I don’t know about them.

If the page is blank, or half-completed then there is likely a fatal error somewhere. Your server logs should reveal a message of what and where the error is.

Do you want the full listing in the header of every page or just the letters? If you want the letters only then you could either use the Widget in an appropriate sidebar, or you can use the_a_z_letters() function.

Your query in the example you posted which isn’t working is not a valid WP_Query. The post_type item needs to be at the same level as the tax_query item:

<?php
the_a_z_listing( array(
    'post_type' => 'post',
    'tax_query' => array(
        'taxonomy' => 'category',
        'terms'    => array( 'my-boat' ),
    ),
) );

This function as above will show the complete listing, which might be correct, or you might want the letters only in which case replace it with a call to the_a_z_letters() instead of the_a_z_listing(). Both functions use the same argument, so the array can remain the same:

<?php
the_a_z_letters( array(
    'post_type' => 'post',
    'tax_query' => array(
        'taxonomy' => 'category',
        'terms'    => array( 'my-boat' ),
    ),
) );

OK,

Sorry about the long delay in replying. I’ve put together an updated version, which might solve this problem for you. It is available at https://github.com/diddledan/wp-a-z-listing/archive/2.0.zip as a pre-release, and includes some caching strategies. When the cache is cold, though, it will still take a lot of memory and time to build the page.

It looks from your error above that the memory exhaustion occurred in meta.php from WordPress core. That would indicate that perhaps the problem is related to a large amount of metadata on your posts. It would be interesting to see if you could isolate whether the plugin fails on your posts in isolation or whether it is a combination of plugins which is causing the issues.

For reference, I’ve just tested the 2.0 preview on a local system with a memory limit of 128M and 10,000 posts without hitting the limit.

If you can, make a complete backup of your site in case the next steps go awry, and then:

1. Download the wp-content/uploads folder to your local PC – check there are no PHP scripts inside that folder once you have it. If there are any PHP files delete them unless you specifically know about them and why they’re there
2. Make a list of all the plugins you have on your site and download them from their original sources (updating if you can to the latest versions released)
3. If your theme is not customised or home-made try to download the latest version from the original source – If you’ve customised it then make sure you can duplicate the customisations in the newly downloaded theme
4. Save wp-config.php to your home PC and check to make sure there are no nasty injected things inside it – compare with a clean version and try to make a judgement as to whether the differences are each required for your site – this file tells WordPress how to connect to your database and some other configurations via define() calls and ends in a require() to load WordPress itself
5. Now delete all the files on your site (this is the scary part) and upload a new WordPress extracted from the zip file you can download from WordPress.org
6. Upload your new copies of all the plugins
7. Upload your new copy of your theme with any customisations re-applied
8. Upload your wp-content/uploads folder once you’ve removed the PHP files within – see above
9. Upload your wp-config.php file once you’ve verified there are no backdoors inside
10. If all went well your site should be operational again. If not, delete all the files and restore from the backup you made before you started these steps and you’ll be where you started – see the very first statement 🙂 – The database should still be OK so you don’t necessarily need to restore that too

Don’t worry about it. Mistakes happen. I’m glad that my plugin hadn’t caused your site to be hacked. I was concerned that I had a vulnerability which you were highlighting. If that were the case I would work tirelessly to fix for everyone. I hope you can get your site cleaned up, and that it isn’t too painful a process. Fixing a hacked site is a painful task and I don’t wish the job on anyone. Good luck.

If there’s ever anything I can help with in the future, please come back and ask away 🙂

This is not due to my plugin. The forum moderators and the plugins team have both confirmed that this is not caused by the A-Z Listing plugin. It is likely that your site has been hacked via another route.
