Not sure I understand your specifics, add details if I am off. I assume: Your shortcode inside post’s content. You have custom field in that post with value you want. In this case declare in your shortcode function global $post; and use $post->ID to retrieve custom field.
I’d suggest using Syntax Highlighter Evolved. It’s by Viper007Bond. You can use it like this: [sourcecode lang=”php”] <?php echo ‘Hello World!’; ?> [/sourcecode] Or even like this: [php] <?php echo ‘Hello World!’; ?> [/php] A screenshot: EDIT An example of how you could do the backticks method that SE uses: function wpse13653_content( $content ){ return … Read more
<?php function modified_post_gallery( $blank = NULL, $attr ) { echo ‘<pre>’; print_r( $attr ); echo ‘</pre>’; } add_filter( ‘post_gallery’, ‘modified_post_gallery’, 10, 2); ?> In media.php it shows the filter like this: // Allow plugins/themes to override the default gallery template. $output = apply_filters(‘post_gallery’, ”, $attr); Its passing two variables not one and $attr is on … Read more
$current_user isn’t declared in the scope of that function. You’d want to modify the code to be more like this: function get_form($atts) { $current_user = wp_get_current_user(); return ‘<form method=”post” action=””> <input type=”input” name=”myinput” value=””></input> <input type=”hidden” name=”myvar” value=”‘ . $current_user->ID . ‘”> </form>’; } add_shortcode(‘myshortcode’, ‘get_form’);
It looks like twenty ten displays the excerpt on category archives. If you’re using manual excerpts, this is an easy fix. Just add this line of code to your theme’s functions.php file. It tells wordpress to run the excerpt through the do_shortcode function/filter. add_filter( ‘the_excerpt’, ‘do_shortcode’ ); If you’re not using manual excerpts, we have … Read more
Try: $atts = shortcode_atts( array( ‘title’ => ‘My Default’, ‘year’ => ‘1900’ ), $atts );
WP Issuu plugin doesn’t use the shortcode API. So you can’t use it like a regular shortcode. The plugin is a filter for the_content, that’s why your solution did work. If you want to solve this (use do_shortcode) you have to rewrite the plugin so it uses the shortcode API.
Simply don’t call return more than once. Just add your output to a variable: $some_variable_name=”mention the = at the beginning of this line”; $some_variable_name .= ‘Take a look at the .Period before the = in this line’; $some_variable_name .= ‘then add more lines always with the period’; // at the end of your shortcode function: … Read more
do_shortcode should do the trick. I don’t think you need the ‘echo’ before it though, I have never done so myself and never had any problems.
The global $post object is from the current query, so what you’re seeing is the expected behavior. If you always want the shortcode to return the post_meta from ID = 1, then you should just hardcode that into the shortcode like in @Chris_O’s answer where you just save a variable that equals 1 and pass … Read more
