Display the content of a custom field in the LCP template [closed]

by

Excellent plugin, my only problem is that I can’t get the value of a custom field displayed where I want to.

I have a custom field: imgx
It’s value is an HTML code, specifically for an image, like:

<img src="https://wordpress.stackexchange.com/questions/55563/mydomain.com/xxx.jpg">

I want to place this left of the post title in the template. How do this?
Please post a code sample for the template file.
I tried with ‘echo’, but nothing happens.

Thanks in advance for your help!

Sorry about this, I thought that people would know that if I’m using this tag, it woulf be obvious, that I’m referring to the WordPress plugin List Category Posts. It’s my First time
here guys 🙂

Anyway, here’s the template that I want to get working.
My comments start like this:

 //zzz
        /**
         * The format for templates changed since version 0.17.
         * Since this code is included inside CatListDisplayer, $this refers to
         * the instance of CatListDisplayer that called this file.
         */

        /* This is the string which will gather all the information.*/
        $lcp_display_output="";

        // Show category link:
        $lcp_display_output .= $this->get_category_link('strong');

        //Add 'starting' tag. Here, I'm using an unordered list (ul) as an example:
        $lcp_display_output .= '<ul class="lcp_catlist">';

        /**
         * Posts loop.
         * The code here will be executed for every post in the category.
         * As you can see, the different options are being called from functions on the
         * $this variable which is a CatListDisplayer.
         *
         * The CatListDisplayer has a function for each field we want to show.
         * So you'll see get_excerpt, get_thumbnail, etc.
         * You can now pass an html tag as a parameter. This tag will sorround the info
         * you want to display. You can also assign a specific CSS class to each field.
         */
        foreach ($this->catlist->get_categories_posts() as $single):
            //Start a List Item for each post:
            $lcp_display_output .= "<li>";

            //zzz This is where I look for the custom field (displays nothing):
            $lcp_display_output .= get_post_meta($post->ID, 'imgx', true);

            //zzz This is where I try to display stuff:
            //zzz this works: $lcp_display_output .= 'hello world';
            //zzz this doesn't: echo "hello world"

            //Show the title and link to the post:
            $lcp_display_output .= $this->get_post_title($single);

            //Show comments:
            $lcp_display_output .= $this->get_comments($single);

            //Show date:
            $lcp_display_output .= ' ' . $this->get_date($single);

            //Show author
            $lcp_display_output .= $this->get_author($single);

            //Custom fields:
            $lcp_display_output .= $this->get_custom_fields($this- >params['customfield_display'], $single->ID);

            //Post Thumbnail
            $lcp_display_output .= $this->get_thumbnail($single);

            /**
             * Post content - Example of how to use tag and class parameters:
             * This will produce:<p class="lcp_content">The content</p>
             */
            $lcp_display_output .= $this->get_content($single, 'p', 'lcp_content');

            /**
             * Post content - Example of how to use tag and class parameters:
             * This will produce:<div class="lcp_excerpt">The content</div>
             */
            $lcp_display_output .= $this->get_excerpt($single, 'div', 'lcp_excerpt');

            //Close li tag
            $lcp_display_output .= '</li>';
        endforeach;

        $lcp_display_output .= '</ul>';
        $this->lcp_output = $lcp_display_output;

Add a line like this for each custom field you’d like to display in your template code. You can display multiple custom fields. You may have to comment out the default custom_field_display line. 

$lcp_display_output .= $this->get_custom_fields('custom_field_name', $single->ID, 'span', 'class_name');
    // you can copy and paste this line, changing custom_field_name for each custom field you'd like to display    

    //    $lcp_display_output .= $this->get_custom_fields($this->params['customfield_display'], $single->ID);
    // may have to comment out default custom display to call one specifically

Then you can use the shortcode to call your custom fields from within your page content area in your WP admin. 

[catlist customfield_display="custom_field1,custom_field2" customfield_display_name="no"]

Info on shortcodes and creating a custom PHP template for the a specific cat-list are here:

Hope that helps.
