The following function shows you some “best practice” example 😉 It includes error handling, checking for emtpy array values, parsing input args with defaults, cares about if you want to echo the result, etc. You even got a filter for your child themes defaults. 🙂 The function in your functions.php file: function wpse15886_check_cat( $args = … Read more
I would build the input fields for terms as array of inputs. Like this (note the [] inthe name attribute: <input name=”input_name[]” type=”text” value=””> <input name=”input_name[]” type=”text” value=””> <input name=”input_name[]” type=”text” value=””> Then, in PHP: //Now $_POST[‘input_name’]; is an array //get the array and sanitize it $input_terms = array_map( ‘sanitize_text_field’, $_POST[‘input_name’] ); //Set the array … Read more
this should do it: $categories = get_categories(); foreach( $categories as $category ) { echo ‘<input type=”checkbox” name=” . $category->slug . “” value=”‘ . $category->term_id . ‘” /> ‘ . $category->name . ‘<br />’ . “\n”; } and you can change/order the list by feeding arguments to get_categories(): http://codex.wordpress.org/Function_Reference/get_categories
WP has a lot of nifty functions in the corners for such stuff. Try this: if ( !empty( $categories ) ) { $excluded_categories = wp_list_pluck( $categories, ‘term_id’); $excluded_categories = implode(‘,’, $excluded_categories); }
Try this: $posttags = get_the_tags(); $count=0; if ($posttags) { foreach($posttags as $tag) { $count++; echo ‘<a href=”‘.get_tag_link($tag->term_id).'”>’.$tag->name.'</a> ‘; if( $count >4 ) break; } }

No, this won’t work: <?php echo get_option(‘notice_data[Message]’); ?> Because get_option pulls whole option value by option_name, it doesn’t pull by pieces of the serialized array. What you are asking for is a key (option_name) called literally notice_data[Message]. Assuming you’ve saved the option as notice_data you aren’t going to get a match, and I am not … Read more
You’re saving every query object for each category to the same transient. Because this happens fast and time frame is one day, you’re always getting the query object for the first category back. Make your transient name variable with the category, e.g. like this: $query_category_posts = get_transient(‘cached_posts_’ . $category ); Of course you then need … Read more
Contact Form 7 has a lot of useful hooks you can use to tie custom code into it at various points of the form submission process. They are tragically not well documented at all but you can find them by googling around. You probably want wpcf7_before_send_mail. Something like this in functions.php: function do_stuff($wpcf7) { // … Read more
Based on your example at the bottom of your question, and your statement that you would like something like that for readability, I’d do something like this: function dropdown_option($atts) { $dropid = (isset($atts[‘dropid’])) ? $atts[‘dropid’] : ”; global $sco_array; if (!empty($atts[‘value’]) && !empty($atts[‘text’])) { $sco_array[$dropid][$atts[‘value’]] = $atts[‘text’]; } } add_shortcode(‘sco’,’dropdown_option’); function sc_dropdown($atts) { $id = … Read more
