wordpress-plugin

问题 I'm curious how plugins work, I just know that instead of changing the code we use plugins, but how do they do their job without changing the code ? and what should a coder consider when coding a new project so it can have plugins ? and thank you very much :D 回答1: There are multiple variations on how to implement a plugin system. Wordpress uses a quite common scheme often described as "hooks." I don't know the exact implementation but it basically works like this: // plugin.php script

问题 I have a form with some fields, and a wpdb table which corresponds to the fields. I want the data from the form to be submitted into the table when the submit button is clicked on the form. Here is the form: function display_form(){ echo ' <form action="insertrow.php" method="post"> <p>Ticket id: <br /> User id: <br /> Description: <textarea class="widget" rows="4" cols="1" name="ticket_description"></textarea> Priority: <select name="ticket_priority" placeholder="Select"> <option value=

问题 I am using the ACF plugin (2.1.4 - latest version) for WordPress (3.2.1 - latest version). Everything seems to work fine, except for when I use a WYSIWYG field. Any paragraph tags used are not saved to the database. TinyMCE is inserting them when I go to the HTML view, but as soon as I save and look in the DB tables, no paragraph tags are found. This does not seem to affect other HTML like 'strong' tags etc however, interestingly enough, it does seem to affect 'br' tags as well. When I save a
