You need to specify a list of allowed mime types. You could make it easy by just getting the allowed mime types like: $file = $_FILES[‘the-file’]; $upload_file = wp_handle_upload($file, array( ‘test_form’ => false, ‘mimes’ => get_allowed_mime_types() )); If you look at the codex for Default allowed mime types, you could manually specify which ever mime … Read more
I normalize the output of these functions using this logic: Cast the value to an array. If it is not an array already, it will be converted to an array with one element, which is the value it was, e.g. (array) false becomes array (false). Use array_filter, which, when not passed a callable, simply filters … Read more
This happens, because WP checks the value with empty(): if ( ! empty( $value ) ) … and empty() is TRUE for values like 0 or “0”. You have two options now: Filter walker_nav_menu_start_el and replace <a with <a tabindex=0. Pass $atts[‘tabindex’] = “0 “; in your original function. Note the extra space. It circumvents … Read more
This is not really a WordPress question but more PHP. To solve this problem, you need to use $value as your key as well plus _id You can do something like this $options[$value . ‘_id’] = ot_get_option($value); EDIT If you need $key to be the value of id, you can also try something like this … Read more
Your data is being serialize properly. Your code saves an array of integers. Integers are not strings and so a string length is not saved. Run the following code and it should illustrate the point: $str=”a:4:{i:0;s:4:”7613″;i:1;s:4:”7615″;i:2;s:4:”7616″;i:3;s:4:”7618″;}”; $str = maybe_unserialize($str); var_dump($str); echo ‘<br/>’; var_dump(maybe_serialize($str)); echo ‘<br/>’; $str = array( 1234,4567,8910,1112 ); var_dump(maybe_serialize($str)); echo ‘<br/>’; $str = … Read more
You need to pass author__in as an array but that isn’t what you doing with this: ( array( ‘author__in’ => array( $followed ) ) ). You are creating an odd set of nested arrays. WP_Query isn’t going to know what to do with it. A much simplified version should work: $followed = $wpdb->get_col(” SELECT user_id1 … Read more
It is all fine. You just need to declare variable global first then you can set the value of this and access globally. function my_free_shipping( $is_available ) { global $woocommerce, $product_notfree_ship; // set the product ids that are $product_notfree_ship $product_notfree_ship = array( ‘1’, ‘2’, ‘3’, ‘4’, ‘5’ ); Then again declare it globally when using … Read more
After some more testing it became apparent that the results weren’t in fact doing natural sorting. I made a few changes. It’s ugly… but it works. Okidokes, so I wasn’t able to get this to sort the way I wanted using WordPress’ sorting functions so I did go the usort route, and I think it … Read more
Here’s the relevant part of your code that should work: // This will make a URL like http://yoursite.com/path/to/fallback.png $fallback_image = site_url( ‘/path/to/fallback.png’ ); $fallback_image = “<img src=”https://wordpress.stackexchange.com/questions/224740/{$fallback_image}” />”; foreach( $recent_posts as $recent ){ echo ‘<div class=”sidebar-entries”>’; $featured_image = get_the_post_thumbnail( $recent[‘ID’], ‘sidebar-thumb’, array( ‘class’ => ‘sidebar-image’ ) ); if ( ! strlen( $featured_image ) ) { … Read more
Answering my own question again. 😛 I finally found this Gist that lets me get and set array variables via dot notation: https://gist.github.com/elfet/4713488 So I included the DotNotation class and now my code looks like this (skipping all sorts of error checking here) : $fieldmap_string = ‘key1.key2.key3.etc’; $current_page_content = get_field(‘page_content’, $source_post_id); $parsed_current_content = new DotNotation($current_page_content); … Read more
