Taxonomies in WordPress don’t work like in biology or similar fields. They are not mutually exclusive. There are some ways to simulate such a behavior (see post formats for an example), but in general you have to expect cases where on post object belongs to more than one taxon (term). And there is no really … Read more
If you are implementing your car and models as custom taxonomies, then this plugin will probably help you out. http://wordpress.org/extend/plugins/query-multiple-taxonomies/
So checked is fairly simple to understand. It compares the first two values. If they’re equal, it spits out checked=”checked” if they aren’t equal nothing happens. <?php $saved = ‘on’; $compare=”on” // spits out checked=”checked” checked($saved, $compare); $saved = ‘off’; // does nothing checked($saved, $compare); How you save check boxes it up to you. Because … Read more
The options are saved as an array under a single key, what you see in the db is serialized data. WordPress takes care of unserializing the data when the option is loaded, so you can reference each individual option the same way you’d reference an element in any php array: $my_options = get_option(‘RWWA’); echo $my_options[‘colour’];
When you save an array of data in an option, WordPress serializes it to save, then when you use get_option, it gets unserialized back into the original array, so it can be accessed as you’d access any indexed array without keys in php: original option added: $hsv = array(‘hval’,’sval’,’vval’); add_option(‘hsv’, $hsv); then, to access this … Read more
I can’t comment on your code, but you might find this link useful: Options Framework Theme: http://wptheming.com/options-framework-theme/ This is something you have to edit carefully, but it has pretty much every type of control you can think of in there. It also had the only working MCE Editor that I could find. I wanted that … Read more
When you redirect via wp_safe_redirect, this is done by sending a header to the browser containing the URL to redirect to. If any content has been sent to the browser before trying to send this header, you get the headers already sent error. Once content goes to the browser, happy header time is over, no … Read more
In the following code, $i is not going to be your category ID. foreach($slidercats_array AS $i => $value) { $cat = get_category($i); // cat_ID if ( empty( $cat ) ) unset($slidercats_array[$i]); } At least I don’t see how it could be. If you explode a string the keys in the resulting array are numerical and … Read more
I don’t know if there is really a right answer to this question, and I don’t know what you find cumbersome about wp_localize_script, but you should be able to do it either way. The difference is that with wp_localize_script the data is printed to the source of the page, which you wouldn’t want if the … Read more
I believe you should be able to use the update_option_{$option} hook: do_action( “update_option_{$option}”, $oldvalue, $_newvalue ); Something like: add_action( “update_option_youroptionname”, function ($oldvalue, $_newvalue) { // process your option value and update/insert options as needed // var_dump($oldvalue, $_newvalue); // debug // wp_die(); // debug }, 1,2 ); Be sure to replace “youroptionname” with the appropriate value.
