Hiding a when custom field is empty

Hi Guys,

Video site questions continued... I need to hide the video embed <div> when there is no video url to embed...

I am using CustomPress custom fields...

    Hi there @aircooled76

    I hope you are well today and thank you for your question.

    You want to completely hide the div and all content, if there is no content to be inserted? In that case your going to want to add a else statement to that above code.

    Some possibly handy links for you to take a look over:

    Ok. I don't know CustomPress off the top of my head but you should be able to test for a variable value using:

        if (isset($variable)) {
           echo "Variable is set";

    So if your variable is "$ct_Video_URL_text_a90a" (wow, that's complex) then...

        if(isset($ct_Video_URL_text_a90a)) {
            // Do Stuff Here
        } else {
            // Do something else

    isset() in PHP is the equivalent of not null (!null).

  • aircooled76

    OK... I added in the test code and it does not echo the "Variable is set"...

    I also did the following code and got the response "Do something else" (same as variable not set)

        if(isset($ct_Video_URL_text_a90a)) {
            echo "Do Stuff Here";
        } else {
            echo "Do something else";

    So the ct_Video_URL_text_a90a must not be the correct reference.... It is however working in the embed code for the Custom field
    <?php echo do_shortcode('[ct id="ct_Video_URL_text_a90a" property="title | description | value"]'); ?>

    Any suggestions... this is holding me up quite a bit ATM...

    This is a common mistake that people make when they don't understand how programming works. Just because it looks like it should be simple, that doesn't mean it will be the case.

    A shortcode is essentially a PHP function. You are feeding it specific variables and it is being executed. Just because you don't see the engine under the hood doesn't mean it runs by magic.

    In this case, what you want to do is a bit scary if you don't know any PHP but it's fairly elementary as far as this sort of thing goes. All we need to know is the name of the custom field you are checking against. We should be able to pull that out of the CustomPress configuration if you can post a screenshot of the full page.

  • Imperative Ideas

    Also, no, there is not an easier way to achieve this. You are asking how to write a conditional statement based on a field that your only interface with, thus far, is via shortcode.

    A shortcode is like buying a T-Shirt in "small, medium, large, x-large" and "black, white, gray, red, blue"

    What you're after is more like sewing it yourself but it's not as complex as farming and processing your own cotton/dye.

    WOO HOO!!!!! It is working!


    Thank you so much for your help.... It is all a little bit like magic :stuck_out_tongue:

    global $wp_query;
    $postid = $wp_query->post->ID;
    $videoyn = get_post_meta($postid, 'ct_Video_URL_text_a90a', true);
    if (isset($videoyn)) {
    echo "do something";
    } else {
    echo "do something else";}

    where $videoyn is my made up variable to use in the next section of code.


    'ct_Video_URL_text_a90a' is my CustomPress short code reference

  • aircooled76

    Ok... The conditional statement is working fine, but when I go to "echo" my html code into the php doc.... I am having some trouble....

    My flowplayer video code has many single quote marks ' and php shortcode actions....

    so if i echo ' and use the single quotes to wrap the div tag..... the ' s in the code end the echo... and I have to end and start the echo before and after each php function....

    is there a better way to call the HTML code for the video player?

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
