How to get user ID’s from multiple usernames?
Your call to get_user_by() has a small hiccup in it. It needs to be login rather than user_login // Search these Usernames $usernames = array(‘user1’, ‘user2’); // Fetch the User IDs $prof_ids = array(); foreach ($usernames as $prof_id) { $user = get_user_by(‘login’, $prof_id); $prof_ids[] = $user->ID; } // WP_User_Query arguments $args = array( ‘include’ => … Read more
WordPress loop by meta key that is an array? and how loop multiple arrays
You can’t order by values inside serialised arrays in post meta. When you store an array like this: $value = [ [ ‘plan_name’ => ‘name 1’, ‘plan_price’ => ‘1’, ‘theType’ => ‘yesPaid’, ‘plan_space’ => ‘Unlimited’, ], [ ‘plan_name’ => ‘name 2’, ‘plan_price’ => ‘3’, ‘theType’ => ‘yesFree’, ‘plan_space’ => ‘5000’, ], [ ‘plan_name’ => ‘name2’, … Read more
Remove empty terms from array, sort alphabetically, update back to repeating field
$boat_safety_terms_cleaned_sorted = sort( $boat_safety_terms_cleaned ); error_log( print_r( $boat_safety_terms_cleaned_sorted, TRUE ) ); PHP’s sort accepts an array reference and sorts in-place, and returns success or failure – hence the 1 you’re getting. You want: sort( $boat_safety_terms_cleaned ); error_log( print_r( $boat_safety_terms_cleaned, TRUE ) ); Also, I’m assuming I’ll want to use update_post_meta to save the array back … Read more
List a maximum of ‘x’ product categories with qty of ‘y’ in each column
So this is different from your code (and the one in the accepted answer to the other question), but it worked well for me: You can remove the “\t” . and . “\n” which I added for pretty formatting purposes so that you could better inspect the generated HTML markup. And let me know if … Read more
If Array Values Match Another Array’s Values, Then
Here’s one way to solve this: sort both arrays loop through them and compare them item by item (they should be equal, because arrays are sorted) . sort( $evaltypesReq ); sort( $evaltypesSch ); $containsAllValues = true; foreach ( $evaltypesReq as $k => $v ) { if ( $evaltypesSch[$k] !== $v ) $containsAllValues = false; }
How to access or parse key/values that have “string”
In it’s current state you would directly get the value from the associative PHP array by directly referencing the key like so: var_dump( $form_data[‘key’] ); It’s wise to note that when you dump variables using var_dump you get information on the value type, and length. So in this case you get string(33) which indicates the … Read more
Link To Child Category For A Post
You can use get_category_link() for that: $allCat = get_the_category(); if( ! empty( $allCat ) ){ $lastCat = array_reverse( $allCat ); $last_cat_link = get_category_link( $lastCat[0] ); if( ! is_wp_error( $last_cat_link ) ){ echo ‘<a href=”‘ . $last_cat_link . ‘”>’ . $lastCat[0]->name . ‘</a>’; } } https://developer.wordpress.org/reference/functions/get_category_link/
Obtaining array item from WordPress revisions output

Loop over Array and get the distinct ids
No, that’s because you are treating an array as an object and PHP doesn’t convert those types automatically. To get an individual element from an object you use: $my_object->Element1; To get an individual element from an array you use: $my_array[Element1]; You can even nest arrays. So if you have $my_array, where each element is another … Read more
