I’m following the turtorial [here](https://make.wordpress.org/core/2020/07/30/recommended-usage-of-the-updates-api-to-support-the-auto-updates-ui-for-plugins-and-themes-in-wordpress-5-5/), but I saw others articles has this line of code `if (empty($transient->checked)){ return $transient; }` which I’m not sure what it does and if I need it.

But do you mean the function `handle_data ()` will not be include/require on the form page? If it’s true, then my question is solved. * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [Sequence of admin_post and admin_menu](https://wordpress.org/support/topic/sequence-of-admin_post-and-admin_menu/) * Thread Starter [ace0930](https://wordpress.org/support/users/ace0930/) * (@ace0930) * [3 years, 8 months ago](https://wordpress.org/support/topic/sequence-of-admin_post-and-admin_menu/#post-16205297) * [@threadi](https://wordpress.org/support/users/threadi/) From the [doc](https://www.php.net/manual/en/function.header.php) * > Remember that header() must be called before any actual output is sent, either > by normal HTML tags, blank lines in a file, or from PHP. * Normally, we will have another file/script to handle the form like, right? Assume` index.php` has a form and it looks like this: * ```
``` * Then in the `process.php` file, we use `$_POST` to get the data like this ( call this “example-1” for later reference ): * ``` $name = $_POST['name']; header ( "Location: https://example.com" ); // Redirect user to https://example.com after processing the data. ``` * But if we put the processing code above on the same file ( `index.php` ) and it looks like this ( call this “example-2” for later reference ): * ```
``` * It would cause an error because there is already an output ( the form ) before the `header ()`. * Now let’s get back to the “WordPress” way of handling form, we will use the hook` admin_post_{$action}` with a function like: * ``` add_action( admin_post_handle_data, handle_data ); ``` * Then we write the processing code inside `handle_data` like the below: * ``` function handle_data () { $name = $_POST['name']; header ( "Location: https://example.com" ); } ``` * The form page is created by `add_menu_page` with the `admin_menu` hook. * My question is: 1) Will this function `handle_data ()` be include/require on the form page? If it does, it will look like the “example-2”. * 2) If the question “1)” is a yes, then the sequence matter, whether it’s `admin_post` first or `admin_menu` first. If it’s `admin_post` first, then the function `handle_data()` is before the form; If it’s the `admin_menu` first, then the function `handle_data()` is after the form. * Or am I complicating it, WordPress will just do the traditional way like “example- 1” where the processing code is in another script/file? - This reply was modified 3 years, 8 months ago by [ace0930](https://wordpress.org/support/users/ace0930/). * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [Sequence of admin_post and admin_menu](https://wordpress.org/support/topic/sequence-of-admin_post-and-admin_menu/) * Thread Starter [ace0930](https://wordpress.org/support/users/ace0930/) * (@ace0930) * [3 years, 8 months ago](https://wordpress.org/support/topic/sequence-of-admin_post-and-admin_menu/#post-16205190) * [@threadi](https://wordpress.org/support/users/threadi/) Hi, sorry but I don’t think you understand the question… * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [SQL – Single quotes and backticks for query](https://wordpress.org/support/topic/sql-single-quotes-and-backticks-for-query/) * Thread Starter [ace0930](https://wordpress.org/support/users/ace0930/) * (@ace0930) * [3 years, 8 months ago](https://wordpress.org/support/topic/sql-single-quotes-and-backticks-for-query/#post-16203000) * [@bcworkz](https://wordpress.org/support/users/bcworkz/) It returns `NULL` when I echo `prepare ()` if I `%s` the table name. * And I found this line in the source code: `$query = preg_replace( '/(?
``` * Instead, it’s in a function that would be called once the form is submitted to the `admin-post.php` with this [hook](https://developer.wordpress.org/reference/hooks/admin_post_action/). And it looks like this: * ```
``` * Which mean the `wp_safe_redirect ( $example )` will not trigger until the function is called. * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [SQL – Single quotes and backticks for query](https://wordpress.org/support/topic/sql-single-quotes-and-backticks-for-query/) * Thread Starter [ace0930](https://wordpress.org/support/users/ace0930/) * (@ace0930) * [3 years, 8 months ago](https://wordpress.org/support/topic/sql-single-quotes-and-backticks-for-query/#post-16198609) * [@bcworkz](https://wordpress.org/support/users/bcworkz/) Is that mean the `$table_name` shouldn’t be replace by `%s`like the below: `$wpdb -> prepare ( "SELECT !value! FROM !$table_name! WHERE !name! = %s", $name )` * Instead and although the below matches the principle of `sprintf` but it won’t work with `$wpdb -> prepare`: `$wpdb -> prepare ( "SELECT !value!

It’s my fault not to mention that the redirect code is in a function that will be triggered after the form is submitted using this [method](https://developer.wordpress.org/reference/hooks/admin_post_action/). So the redirect code is not on the page itself… * Thank you so much for your advice! * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [Passing function into wp_safe_redirect](https://wordpress.org/support/topic/passing-function-into-wp_safe_redirect/) * Thread Starter [ace0930](https://wordpress.org/support/users/ace0930/) * (@ace0930) * [3 years, 8 months ago](https://wordpress.org/support/topic/passing-function-into-wp_safe_redirect/#post-16196049) * [@bcworkz](https://wordpress.org/support/users/bcworkz/) Okay, cannot believe this mistake took me two days, I think I know why. * Because the action of the form is set to `admin-post.php`, of course, the current URL would always be that…LOL * But you may still explain why `$_SERVER['REQUEST_URI']` may cause so many redirect error. * Forum: [Developing with WordPress](https://wordpress.org/support/forum/wp-advanced/) In reply to: [SQL – Single quotes and backticks for query](https://wordpress.org/support/topic/sql-single-quotes-and-backticks-for-query/) * Thread Starter [ace0930](https://wordpress.org/support/users/ace0930/) * (@ace0930) * [3 years, 8 months ago](https://wordpress.org/support/topic/sql-single-quotes-and-backticks-for-query/#post-16195363) * [@bcworkz](https://wordpress.org/support/users/bcworkz/) I found a relevant question although I don’t understand what the answer is talking about: [https://wordpress.stackexchange.com/questions/25764/cant-pass-table-to-wpdb-prepare](https://wordpress.stackexchange.com/questions/25764/cant-pass-table-to-wpdb-prepare) * > quotation marks are added to the table name * So `$table_name = $wpdb -> prefix . testing;` will become `"wp_testing"` according to the answer?
