php - concrete5 custom block not passing array to view -

-

I have a custom block made in Concrete 5, it gets an array of all workers from the database and pass it in the view Does it. This block also uses the parameter which is blocked when the block is added to a page (its a part of the WHERE sql statement, i.e. parent_id = 261) Here my task is in Block Controller: 

  public function view () {$ db = new mysqli (WP_SERVER, WP_USERNAME, WP_PASSWORD, WP_DATABASE); If ($ db-> connect_errno & gt; 0) {echo '& lt ;! - Unable to connect to database ['$ db- & gt; Connect_uper '] - & gt;'; } Other {$ SQL_ENTRIES = "SELECT * FROM` wp_posts`]" where post_type = 'page' and " Post by replacing $ query. "(Post_ title, 'pound', 'lz')" ACC "; If (! $ Entries_result = $ db- & gt; Query ($ SQL_ENTRIES)) {echo ' ft_sock ()) $ entries [] = $ line; $ SQL_META = "SELECT post_id, meta_key, meta_value fp wp_postmeta WHERE in post_ id (select` wp_posts` id where post_type = 'page' and '. $ Query.') "; If (! $ Meta_result = $ db-> Query ($ SQL_META)) {echo ' fetch_assoc ()) {ifet! ($! [$ Row ['post_id']])) $ Metas [$ row ['post_id']] = array (); $ Metas [$ row ['post_id']] [] = $ line; } $ Updated_entries = array (); ($ Meta [$ entry ['id']])) {foreach ($ meta [$ entry ['id']] $ {$ entry [$ meta] ['meta_key']] = $ meta as meta [ 'Meta_value'];}} $ Updated_entries [] = $ entry;} $ this-> set ('updated_entries', $ updated_entries);}}}}

and my views In the file: 

  $ get = $ updated_entries; echo json_encode ($ received);

It lists nothing, which is strange, because When the function is placed inside the view file, then it lists everything as usual My guess is that because of your code using a $ query

> Variable, but it is not defined anywhere in the function. If this code works in your view file, then I have a condition that the $ query variable is set in the view itself Or maybe it is WP_SERVER , WP_USERNAME , WP_PASSWORD , and WP_DATABASE constants that you are going through in a database connection ? Where are they coming from?

Side note: I actually expect that it has run properly to avoid the $ query SQL injection. If you are taking some arguments from $ _GET or $ _POST and feed them in $ query then you have a distance protection hole.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
