The error message you get means that a function has been hooked without a valid callback. In other words it means that somewhere in your theme or in a plugin a function has been set but it’s not “hooked” properly. See the example : function add_post_content() //<- the callback { // blabla } add_action( ‘hook_name’, … Read more
Are you sure editor use <i> for italics? I’m almost sure it uses <em>. However, if you want to be absolutely sure there are no <i> in your post content, let editor do what it want and then replace <i> with <em> before creating/updating posts, hooking wp_insert_post_data filter, just like: add_filter(‘wp_insert_post_data’,’replace_em’, 20, 1); function replace_em( … Read more
“best” greatly depends on context. guid is probably (with some debate about it) the best way to uniquely identify a post, but not all import/export plugins leave it alone without changes. ID is a good identifier if you do not care about import and export. Slug is problematic because they might be changed by the … Read more
I don’t think this is possible. Watermarking the audio with an audio editing software takes a process that ‘WordPress’ cannot simulate. It’s advisable you do the watermarking before the audio file is uploaded.
You can insert the quicktag <!–nextpage–> into a post. Using wp_link_pages() you can generate the pagination links.
the_content() does not grab the PHP file content.php, it simply displays a Post’s content. Likewise, the_excerpt() grabs the excerpt of a post. get_template_part simply finds a file within your theme named whatever you put in, with an optional suffix. get_template_part( ‘content’ ); // content.php get_template_part( ‘content’, ‘my_page’ ); // content-my_page.php in order for make different … Read more
The alternative way. Problem with @david.binda solution is that: you have to hardcoding a lot of things, (manually write db credientials, table prefix..) You cannot use content filter (so if you have shortcode in your page, you will see some [something] instead of desired content..) sure you can load wordpress environment, but… Just yesterday I … Read more
You are under a fundamentally wrong assumption: The content you input via the administrative back-end does not live in a file, but in the database, specifically in the wp_posts table. Do not be misguided by the table’s name, a “page” is technically a post of type page. If you attempted to find the content you … Read more
The variable $count is accessible in the scope of the current function only. So whatever happens inside get_template_part() cannot know that variable. You could use a global variable, which is accessible everywhere as $GLOBALS[‘count’]. But then you risk collisions with plugins and maybe other code. I recommend a helper function for the functions.php: /** * … Read more
Stewart, there is a simple way to make the admin area present more simply with two plugins. You can certainly optimize the output of what these plugins will give you, but they can at least get you started. First, you want to create a new custom post type. Custom Post Types UI is a simple … Read more
