PHP - Return Resource Location But Don't Follow With Same Method
I have a class ServerBridge which is used to proxy browser ajax requests received by a web server to another API server. To update a record (or create a record is similar): Browser client makes PUT request to web server. Web server modifies the uri path and passes the body plus headers connection, accept, accept-encoding, accept-language, content-type, content-length only to the API server. The API server does work and returns the location of the resource on itself to the web server. The web server modifies the location header to point to the resource location on itself, and returns all received headers except Date, Server, X-Powered-By, Access-Control-Allow-Origin, Access-Control-Allow-Methods, Access-Control-Allow-Headers to the browser client. Browser client makes another undesired PUT request to web server.Why is step 5 occurring and how do I prevent it? I don't really mind the browser client making another request to the resource, but it would need to be GET and not PUT. Also, is my white-list headers to forward to api server and black-list headers to return to browser client appropriate? I haven't posted the ServerBridge script (but can if needed), but did include the requests and headers related to the browser client, web server, and api server below. Browser client JavaScript

Can you please give me a push in the right direct here? Edited January 30, 2020 by JonnyDrillerHi I have a problem with the following: Code: [Select] <?php class ClassA { public $propertyClassName = "ClassB"; public function methodClassName() { return "ClassB"; } } class ClassB { public function bmethod() { echo "great!"; } } //works $a = new ClassA(); $b = new $a->propertyClassName(); $b->bmethod(); //doesn't work $a = new ClassA(); $b = new $a->methodClassName(); $b->bmethod(); ?> Of course I could do Code: [Select] <?php $a = new ClassA(); $className = $a->methodClassName(); $b = new $className; $b->bmethod(); ?>but isn't there a way to do this without saving the method's return to a variable?

I am trying to do the following. Except I know that 'return' is not the right method to use, as it stops the script, so what ends up happening is only one row is returned, instead of the three that are there. With return, the data is being passed without being immediately printed, and I end up with the data (but not all of it, because the script stops) in correct place in the page. If I replace return () with echo(), it works fine, in terms of returning the correct data. However, with the way things are setup, if I use echo, the results print at the head of my page. I am using function CreateSideMenu to establish the values for content, and then another function, later on the index.php page, actually creates the page. So what I need is to have something, similar to return (), that passes the information on, but does not immediately print it. Do I make sense? see code below: function CreateSideMenu () { // open CreateSideMenu function include ('/Users/max/Sites/rdbase-llc/hidden/defin/kinnect01.php'); $query = "SELECT content_element_title, content_element_short_text FROM content_main"; $result = mysql_query ($query, $dbc); while ($row = mysql_fetch_array ($result, MYSQL_ASSOC)) { return ("<p>" . $row[content_element_title] . "</h2>\n<p>" . $row[content_element_short_text] . "</p>"); } Thanks ahead of time.
My script has 3 classes (that are relevant to this discussion): DB, User and Validate. They are all in independent files and loaded automatically, when required, by an autoloader.
The error messages I am getting a Any pointers as to what I am doing wrong, or what I should be doing, would be most welcome. This piece of code works perfect if the user has a $id listed in DB and is returned from the SQL Query that collects the need values, which first follws this piece of code. However, if the user does not have a $id in that table, it should do the else if, but it goes straight to the last else. What should the else if($id == ' ') or else if(empty($id == ' '))??
