Hidden field – Custom Value – how to get a value

Hi @alena353,

Thank you for contacting us.

Did you also make sure to enable the option “Populate Field from URL” in advanced tab?

In order to better assist you, could you please export your form to a drive and share with us the link so that we can check on your setup and run a similar setup to test this for you?

Best,

Hi @alena353,

Thanks for providing that info.

I tested the form by adding it to a test page and using a query parameter in URL, I was able to populate the hidden field. See my test URL: https://jsolofree.tk/form-test/?the-course=theonecourse

And the submission field: https://snipboard.io/Dxu6zj.jpg

Go ahead and make a test by having the form embedded directly on a test page without the popup form and let us know how it goes.

Hi @alena353

Why do you think it doesn’t work with popup, though? And is there a way to make it work?

Could you test our PopUp plugin?

https://wordpress.org/plugins/wordpress-popup/

From my test it looks the code worked using our plugin.

1) Is it possible to automatically embed the field that is not hidden (to do the same thing that we do with hidden field, but to make this field visible to the user and not allow user to change it)?

You can use the HTML field and embed the hidden-1 macro:

It is going to show in the front end but not allow the user to modify the value from the HTML field.

2) When I put a long text in the hidden field, it gets cut and, as a result, I get only part of the value. Is there a way to allow the form to accept longer values in the hidden field?

Could you give an example and we can try to replicate it?

Hi @alena353,

No bother at all.

I was able to replicate the behavior with popup. The reason the URL is not shown is that the actual trigger will just activate with a button click event, but not redirect, which is where the href URL is set for.

I’m going to check with our plugin team if there is any possible way of doing this and get back to you.

Hi @alena353,

Our Plugin team was able to provide a workaround code to allow you to have the popup with form setup and get the hidden field connected to the value from the query parameter. To do this, please set up the following code in either an MU plugin or in your theme’s functions.php file. If it’s the latter, make sure to set it up in a child theme and not a parent theme, so you avoid the code from being erased.

Here is the code:

function hustle_front_custom_script() {	
	if( is_page( array( 101 ) ) ) { // Id, slug, or title of pages having the form.
		$data = 'jQuery(document).ready(function($){
					$(".show-popup").click(function() { // Class name that triggers the popup
						var href = $(this).attr("href");
						if(href.length) {							
							var course = href.substr(href.indexOf("=") + 1);
							if(course.length) {							
								//alert(course);
								$("#hidden-1").val(course); // Id of the hidden field.
							}
						}													
					});					
				});';
		
		// Since WordPress 4.5.
		wp_add_inline_script( 'hustle_front', $data );     
    }	
}
add_action( 'wp_enqueue_scripts', 'hustle_front_custom_script' );

The code uses the class “show-popup” so in case you changed it, it will need to br modified in the code as well. For additional reference on setting up the code via an MU-plugin, take a look here:https://premium.wpmudev.org/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins

Let us know how it goes.

Best,
