You can alter your foreach loop as following to get concert date and city pair in single multidimentional array as following. $concert_query = array(); $i = 0; foreach($c_query as $post) : setup_postdata($post); $concert_query[$i][‘concert_date’] = get_post_meta(get_the_ID(), ‘concert_date’, true); $concert_query[$i][‘concert_city’] = get_post_meta(get_the_ID(), ‘concert_city’, true); $i ++; endforeach; print_r($concert_query);
I’m assuming your $selected variable contains an array of values for the currently selected items? You can’t use selected in this case (with multi select boxes) because it only compares two strings. It won’t test to see if the value is in an array. Instead, use a ternary statement and in_array() <?php foreach ($cats as … Read more
You can build a stack of unique tags, then loop over them again to output. Couple of extra things though – never use query_posts. Secondly, you can be way more efficient in your querying and save a lot of memory in the process: $post_ids = get_posts( array( ‘posts_per_page’ => -1, ‘category_name’ => ‘testing’, ‘fields’ => … Read more
I found a way to build a custom query that goes through the checkboxes the user selected and then adds an array for that value to the query dynamically. That way it checks to see if each value selected is in the serialized array, and then moves onto the next one. Runs a lot smoother … Read more
Array is how PHP represents an array when it is converted to a string: echo array( /* anything in here */ ); // output: Array Fortunately for you, PHP doesn’t really like converting arrays to strings, so it will give an error like this: PHP Notice: Array to string conversion in /somefile.php on line 345 … Read more
Fields in database tables can not contain other types of data than text strings and numbers, and variations of them like dates and times. The field meta_value of wp_postmeta is a text field. So, when you store an array as meta_value you are really storing a string containing the serialized data that represents the original … Read more
Looking at your code – $lastarray will not be an array of ID’s (as you might be expecting), but an array with a single element containing a string of comma separated IDs. $output is already an array of the $attr[‘id’] – try commenting (add // to the start) to the lines starting with $testarray and … Read more
Two things need to be changed 1 – wishlistPost.metadata.wishlist_array which is the metadata returns an object with a string inside, not an array. var wishlist_array = wishlistPost.metadata.wishlist_array[0]; //Get current string wishlist_array += postID + “,”; //Concat new ID to the current string 2 – JSON.stringify(wishlist_array) is not needed as stated above wishlist_array is a string … Read more
Good news! I think you’re making things harder for yourself than they need to be. If I understand your question, you’re looking for rewind_posts(). The always useful Digging Into WordPress has a nice summary of it. Because both tasks involve looping through the same query, you don’t need get_posts() at all. Instead, you’ll want to … Read more
From codex: $meta_value (mixed) (required) The value of the custom field you will add. An array will be serialized into a string. Default: None So <?php add_post_meta(7, ‘fruit’, ‘banana’, ‘apple’, ‘tornado’, ‘bob saget’) To grab them you can also use http://codex.wordpress.org/Function_Reference/get_post_custom_values besides just get_post_meta.
