Save linebreaks in textarea to tpl file with php I want to edit html code in a textarea and then save it to a tpl-file. When opening the template file with my desktop editor the linebreaks should just look like in the textarea, so no n or br-tag (if not actually wanted for the code) in it. Thanks for any help!

php check if gravatar exists header error I'm trying to check if a gravatar exists. When I try the approach recommended in earlier questions, I get an error " Warning: get_headers() [function.get-headers]: This function may only be used against URLs" Anyone seen this or see the error in my code? PS I do not want to specify a default image for gravatar to serve as there could be more than one default possibilities if no gravatar exits. Also, I found a reference to error possibly being related to my ini file which I don't think my host gives me access to. If so, is there an alternative to getheaders? Many thanks. $email = $_SESSION['email']; $email= "person@gmail.com"; //for testing $gravemail = md5( strtolower( trim( $email ) ) ); $gravsrc = "http://www.gravatar.com/avatar/".$gravemail; $gravcheck = "http://www.gravatar.com/avatar/".$gravemail."?d=404"; $response = get_headers('$gravcheck'); echo $response; e...

How can we include php files without specifying the subfolder path Normally we use the following code to include php files inside each other: <?php include_once 'include/config.php'; // OR include 'include/config.php'; // OR include_once $_SERVER['DOCUMENT_ROOT'].'include/config.php'; // ect... ?> But the above codes only apply if the php files are in the root file. I mean, if we move our files into a subfolder. We need to make a change to the code we included in the php files. For example like this: <?php include_once 'subfolder/include/config.php'; // OR include 'subfolder/include/config.php'; // OR include_once $_SERVER['DOCUMENT_ROOT'].'/subfolder/include/config.php'; // ect... ?> What I'm saying is that when we move our php files into the subfolder, then include_once want to see subfolder name like ( include_once 'subfolder/include/config.php'; ). This is a challenging s...

WooCommerce woocommerce_admin_settings_sanitize_option use I'm currently using the action woocommerce_update_option_X to save the settings of my plugin settings page.

Traversal tree - repair please, do you have any tips, where to find code or solution, how to repair traversal tree? I have table with cols lft, rgt, parent_ID and lvl and when I was moving nodes in this tree, I had fail in code so it broke lft and rgt indexes and I need to recount it. One solution, which I think is applicable is getting all nodes from table, store in array for example, clear table and recreate it, but this solution is not so efficient I think. Do you have any tips, how to solve it better?

Can't receive PHP object by using AJAX I can't fetch the php file from the ajax. Firstly an object is created in the PHP file, then it is converted into JSON by using json_encode() function.

REVOKE SELECT ON contacts FROM '*'@'localhost'; Where is the code and what do you want to achieve? – Nico Haase Jul 1 at 7:51 this makes very little sense – smith Jul 1 at 8:03 You have to restrict this feature on application level, not on database level, since I doubt that you create a separate mysql user acvount for each of your users. – Shadow Jul 1 at 8:23 ...
