I'm working on a page template and I'm having trouble working out how I can echo a string of php. Basically I have set up a custom field inside Wordpress for the page called Slider Code, and it asks the user to paste in the slider code given to them so that the appropriate slider is displayed on the page. The slider code given looks like this: [soliloquy id="82"]
The custom field plugin gives me this code to use in the template to echo out whatever is in that field, which looks like this: <?php echo CFS()->get('slider_code'); ?>
In WordPress there is a php function called do_shortcode which enables me to use that code, so it would look like this: <?php do_shortcode('[soliloquy id="82"]'); ?> and the slider would be displayed. So is there any way I can merge that <?php echo CFS()->get('slider_code'); ?> string with the do_Shortcode string? If not, does anyone have any alternative solutions to this issue? I can only think of having to make separate page templates for each individual slider.
EDIT: I have just discovered that the do_shortcode function does not actually work at all with the soliloquy shortcode. It does give me the option of using this code: if ( function_exists( 'soliloquy' ) ) { soliloquy( '82' ); }. However, when I paste this code into the custom field as is, the <?php echo CFS()->get('slider_code'); ?> tag just echos out that text. If I wrap the code in the custom field in <?php and ?> it just comments the code out inside my inspector. How do I get around this?
Check this out.
$slider = CFS()->get('slider_code');
call_user_func('do_shortcode', $slider);
I don't understand why you can't just run do_shortcode(CFS()->get('slider_code')).
Ok. Then try this one. Paste this code in the template file.
<?php
if ( function_exists( 'soliloquy' ) ) {
soliloquy( CFS()->get('slider_code') );
}
?>
And for slider_code input just enter '82'. If you are unable to see what is the template file you have to paste the above given code, then try to see WordPress template conventions.

I'm trying to insert an embed post of Instagram via code using do_shortcode function. This is the shortcode example that Instagram gives on the embed documentation:
[instagram url=https://www.instagram.com/p/bNd86MSFv6/ hidecaption=true width=320]
So I'm trying to call it like this:
echo do_shortcode('[instagram url=https://www.instagram.com/p/bNd86MSFv6/ hidecaption=true width=320]');
The result I'm having is like I was using only the echo function, the shortcode comes as plain text on the browser.
The page that I'm editing is the single.php. And I did a test using a contact form 7 shortcode, it works normally with do_shortcode.
Am I missing something?
Have you created the code for [instagram]? Please post this code for us.
Put this in your functions.php file:
function my_awesome_shortcode( $atts, $content = null ) {
echo "This is my shortcode";
}
add_shortcode( 'awesome', 'my_awesome_shortcode' );
now put:
echo do_shortcode('[my_awesome_shortcode]');
into your single .php file. What is the result? if you get
This is my shortcode
Then it is working, you can use this template to build your instagram one.
Are you trying to insert this code in your pages/posts, or a template file?
For pages/posts, all you need is:
[instagram url="https://www.instagram.com/p/bNd86MSFv6/" hidecaption=true width=320]
For template files:
echo do_shortcode('[instagram url="https://www.instagram.com/p/bNd86MSFv6/" hidecaption=true width=320]')
Since you are not using a plugin, the shortcode has not been defined. You can either use a plugin ( https://wordpress.org/plugins/simple-instagram-embed/ ) or define the shortcode using Mark's suggestion.
I'm currently learning wordpress theme development and for better understanding I have downloaded couple of wordpress theme and seeing their code.
But a line of code I can't understand. here it is-->
<?php echo do_shortcode(sq_option( 'footer_text ' ' ')); ?>
maybe its for footer but how this works and how i can use this function when I will create my own.
do_shortcode is a function you have to use if you want to execute a shortcode inside a custom theme template page see more info on the function here: https://developer.wordpress.org/reference/functions/do_shortcode/
Generally do_shortcode(); is use to get data from shortcode or its attribute to your PHP code or to filter any shortcode returning data. Shortcode can be provided by any plugin.
Not sure about it but in your theme's code sq_option("footer_text"); could be a function which is filtering some text from footer.
The code could be as:
<?php echo do_shortcode( '[contact-form-7 id="91" title="quote"]' ); ?>
Reference Link
do_shortcode () is usefull function-> for excute shortcode in template file
I have to use some WordPress short-codes for a project - but I want them in very specific places, and not in the main content. I need the client to just put them in specific Custom fields. Using ACF, I built a text field specifically for this.
// normal in-code use
<?php echo do_shortcode('[example_shortcode]'); ?>
// ACF field
<?php the_field('my_main_shortcode'); ?>
// ACF field in the do_shorcode
<?php echo do_shortcode( the_field('my_main_shortcode') ); ?>
This renders out [example_shortcode] on the page instead of what I would expect.
I'm guessing this is a standard PHP thing - and I don't know how to escape or concatenate it properly. EDIT - below using get_fields gets me closer...
THEN... with a more complex short-code
<?php echo do_shortcode( '[tf_listview imagesize="medium1" exclude="calendar-link,list-view-title" dateformat="D n.j"]' ); ?>
It breaks somethings like the image by adding "" - which could totally be the way the short-code was written / but basically - I haven't found a solution to using a short-code in a custom field like this.
Bottom line,
I'd like to write: <?php shit_out('my_annoying_shortcode'); ?>
Or something as close to that as possible. AND have it actually work.
Can anyone give me some more direction?
Since you're using echo, you need to use get_field(), which returns the custom meta value:
<?php echo do_shortcode( get_field('my_main_shortcode') ); ?>
I am creating a WordPress plugin where a user can specify a custom loop repeater based on the value of a textarea.
The idea is, a user can use a predefined repeater that ships with the plugin or they can build their own repeater by simply adding html + PHP to the textarea.
Example of a custom repeater:
<h1><?php the_title(); ?></h1> <?php the_excerpt(); ?> - <?php the_time(); ?>
The issue is when I echo/print the textarea value, the WordPress functions within the <?php ?> tags do not execute.
Is what I'm attempting even possible?
Let me explain further...
I am building an installable plugin based on my Ajax Load More script.
This plugin will be only used by site admins and for total control of the display of posts I want to allow them to create a custom repeater.
On the plugin settings page, I want to have a textarea where the admins can add whatever html/php code they want in order to customize the repeater.
My issue is how do I execute the PHP entered within the textarea on the frontend as echoing the value does not work.
Use eval function to change plain text to php code. More about it here
eval('echo "Hello world!"');
will print out "Hello world!" instead of 'echo "Hello world!"'
BUT what if i write to textarea:
die();
One way of doing this is to use the eval() function as Justinas says, but I would strongly recommend you don't use it as I have found it to be unreliable and problematic.
What I would recommend is to write the PHP code in the string you extract from the text area to a file and then include that file where you want the PHP to execute.
So, I would recommend running
<?php file_put_contents($file_path, $contents); ?>
whenever the text area is updated to update the file, then
<?php include_once($file_path); ?>
where you want the code on the front end.
Those wordpress functions will not work unless they are in the Loop, Here is a basic Loop:
<?php if(have_posts()) { ?>
<?php while(have_posts()) { ?>
<?php the_post(); ?>
<?php // custom post content code for title, excerpt and featured image ?>
<?php } // end while ?>
<?php } // end if ?>
I am trying to incorporate an image slider shortcode into a custom WordPress theme template, so that the client will be able to paste the shortcode into the custom field and the template will read this and display it correctly. I do not want the client to paste the shortcode in the body of the post, as the slider needs to be displayed outside of the post wrapper (at full browser width).
I don't know much about php, so would really appreciate any help with this!
The code I have so far to display the slider via the template is:
<?php echo do_shortcode("[metaslider id=27]"); ?>
And to display the output of custom fields I have:
<?php echo get_post_meta($post->ID, 'slider', true); ?>
Each of these works on its own, but I need to combine them, so that the client doesn't have to edit the template just to add the shortcode. So I am thinking something like this should work:
<?php echo do_shortcode("[<?php echo get_post_meta($post->ID, 'slider', true); ?>]"); ?>
... but it doesn't.
Many thanks in advance for any help with this.

Simply pass the return value of get_post_meta (which would contain the shortcode as far as I understood) to the do_shortcode function as an argument:
do_shortcode(get_post_meta($post->ID, 'slider', true));
