Dynamically Insert a Custom Field into a Shortcode

  • Hi there,

    I am trying to dynamically insert a custom field (course ID) into a shortcode.

    The shortcode is as follows

    [learndash_payment_buttons course_id=”INSERT”]

    I am using a custom field to insert course ID for each page and the usual way to call the custom field is:

    <?php getCustomField(‘Course ID’); ?>

    Does anyone know if it is possible to combine the two so I can dynamically call the course ID within the shortcode?

    I have tried a few approaches but nothing seems to work.

    Thanks in advance.

    James

  • getCustomField() is not a native WordPress function and I don’t know how it behaves. If I were using the in-built function get_post_meta() (function reference), I would most likely use it with do_shortcode() (function reference) as follows:

    <?php
       $value_cid = get_post_meta( get_the_ID(), 'the_custom_field_key', true );
       $shortcode_cid = '[learndash_payment_buttons course_id="' . $value_cid . '"]';
       echo do_shortcode( $shortcode_cid );
    ?>

    Where the_custom_field_key is the meta key whose value you want to retrieve.

    This getCustomField() function may produce analogous output to get_post_meta() or it may not. I don’t know. To see if it does, you could start by trying to replace that first line with:

    $value_cid = getCustomField( 'Course ID' );

    Hi there, many thanks for your response! Much appreciated.

    I have tried what you suggested and the output is just the Course ID and it is not including the shortcode.

    Any suggestions?

    CRACKED IT! Thank you very much for your help!! 🙂

    <?php
    $courseID = get_post_meta($post->ID, "Course ID", true);
    $shortcode_cid = '[learndash_payment_buttons course_id="' . $courseID . '"]';
    if($shortcode_cid) echo do_shortcode( $shortcode_cid );
    ?>
