Ok, so this is how I did it, and it’s not an awful hack. So my problem was passing values (in this case, query args) to a callback function from a instance of a class that was created BEFORE the query args existed. The transient approach worked but can break anytime. So when the function … Read more
If you look at the documentation for get_term_by(), you’ll see that it: Will return false if $taxonomy does not exist or $term was not found. You need to account for this possibility in your code by checking the value of $term. You’ll also note from the documentation that get_term_by() does not return a WP_Error, so … Read more
You’re not doing anything unusual or unsafe. You are just defining functions, which is a perfectly normal and reasonable thing to do with JavaScript. If there’s a malicious script running on your page then sure, it could redefine those methods, but it could also do other things that much worse. This is why you need … Read more
If you use the WordPress API to retrieve the metadata, then it should be cached for you. If you do other complex stuff, there is the Transients API for caching data yourself, which will take advantage of whatever object cache you use with WordPress. EDIT – I should clarify, it’ll be loaded for each request … Read more
I’m not 100% sure, but this problem seems related to the unfiltered_html capability restriction. unfiltered_html Since 2.0 Allows user to post HTML markup or even JavaScript code in pages, posts, and comments. Note: Enabling this option for untrusted users may result in their posting malicious or poorly formatted code. An easy fix (and probably a … Read more
The primary loop query post ID is stored in $current. This variable is equivalent to $post->ID. The secondary loop query post ID is available within the loop as $post->ID. Thus, you just need a simple if statement in side your secondary loop: <?php if ( $current == $post->ID ) { // This post is the … Read more
I don´t know any sequence diagram for WordPress but if you decide to built them yourself (which would be appreciated 🙂 ) you may get some inspiration from these sequence diagrams created for Drupal
It looks like the $args passed to the function is not an object for some reason. I can’t see the origin of this problem but for a quick solution, you can add $args = (object) $args; before the first time you use $args, here on line 44 Also, as commented by toscho, dropdown_menu() is not … Read more
The init action… is one of many WordPress core action hooks. Hence it does not require, i.e. should not be accompanied by, a manual do_action call. You only need to manually run do_action for custom, previously non-existent, action hooks. Further, init is not the action which you want to hook the script enqueuing with. There … Read more
If you call BAR the e-mail address is set to [email protected]. But when you call FOO_SEND_EMAIL, the e-mail address is set to [email protected] because it is overwritten by FOO‘s constructor. You run $sendEmail = new FOO_SEND_EMAIL, when you do this the constructor of FOO is called. It has nothing to do with whatever $BAR currently … Read more
