unifiedac Posted March 29, 2011 Share Posted March 29, 2011 Hello, I am new to PHP and have come to a grinding halt in my project. I am attempting to dynamically generate values for Wordpress shortcodes ( [example] ). I have successfully created the shortcodes and am having trouble setting their value. When I call the function that is supposed to return the value for the shortcode, it returns empty. I can however hard code a string and have it returned to the function, thereby manually creating a value for the shortcode. However, because the shortcodes are being generated and filled dynamically, I need this function to work without specific values. I know this may sound like a Wordpress specific question, but I have a feeling it's just my lack of understanding of PHP operations. So, here is the basic layout: The name of the shortcode is generated from within a foreach loop that retrieves the name of custom fields on the post ($keyName). $custom_field_keys = get_post_custom_keys(); foreach ( $custom_field_keys as $key => $keyName ) { $valuet = trim($keyName); if ( '_' == $valuet{0} ) continue; if ( get_post_meta($thePostID, $keyName, true) ) : $fieldName = get_post_meta($thePostID, $keyName, true); endif; $fieldValue = $_GET["$keyName"]; add_shortcode((string)$keyName, 'myFields'); } The add_shortcode function has two parameters ('name_of_shortcode', 'function_name'): add_shortcode((string)$keyName, 'myFields'); I need the myFields function to return the value of $fieldValue from within the foreach loop. That's where the problem lies. This doesn't work: function myFields() { $myString = preg_replace('/[^a-zA-Z\s]/', '', $fieldValue); return $myString; } This does work: function myFields() { return 'Content to replace the shortcode'; } This code will replace [shortcode] with "Content to replace the shortcode" in the post. The ultimate goal is: when [$keyName] appears anywhere within the post, it will display the content returned by the myFields function ($fieldValue). However, it's not working. :'( I can't seem to pass the value of $fieldValue to the myFields function and thereby return it to add_shortcode. Any help is appreciated and I am awaiting anxiously to answer any questions. Here's all the code together: function myFields() { $myString = preg_replace('/[^a-zA-Z\s]/', '', $fieldValue); return $myString; } $custom_field_keys = get_post_custom_keys(); foreach ( $custom_field_keys as $key => $keyName ) { $valuet = trim($keyName); if ( '_' == $valuet{0} ) continue; if ( get_post_meta($thePostID, $keyName, true) ) : $fieldName = get_post_meta($thePostID, $keyName, true); endif; $fieldValue = $_GET["$keyName"]; add_shortcode((string)$keyName, 'yourFunction'); } Quote Link to comment Share on other sites More sharing options...
unifiedac Posted March 29, 2011 Author Share Posted March 29, 2011 I had already tried this, it returns no value. When myFields is called, there is no way to send a parameter. I have also tried this: add_shortcode((string)$keyName, 'myFields($fieldValue)'); Thanks for the interest. Let me know if anything else comes to mind.
