Hi, @maasut!
Thanks for posting your question!
Unfortunately, Form Maker does not have this functionality by default.
However, you can get this by writing a few lines of Javascript code on Form Options > Javascript tab. Please try this.
Firstly, add these two it inside before_load() function:
value = getParameterByName('field');
jQuery("#hidden_id").val(value);
Afterwards add the following code outside of all built-in functions in the editor:
function getParameterByName(name, url) {
if (!url) {
url = window.location.href;
}
name = name.replace(/[\[\]]/g, "\\$&");
var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
results = regex.exec(url);
if (!results) return null;
if (!results[2]) return '';
return decodeURIComponent(results[2].replace(/\+/g, " "));
}
Let us know if this helps.
Cheers!

Thanks!¿Like this?
// Occurs before the form is loaded
function before_load() {
value = getParameterByName('field');
jQuery("#hidden_id").val(value);
}
// Occurs just before submitting the form
function before_submit() {
// IMPORTANT! If you want to interrupt (stop) the submitting of the form, this function should return true. You don't need to return any value if you don't want to stop the submission.
}
// Occurs just before resetting the form
function before_reset() {
}
function getParameterByName(name, url) {
if (!url) {
url = window.location.href;
}
name = name.replace(/[\[\]]/g, "\\$&");
var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
results = regex.exec(url);
if (!results) return null;
if (!results[2]) return '';
return decodeURIComponent(results[2].replace(/\+/g, " "));
}
How should be the url address? Something http://www.mywebpage.com/?id=value
Hello, @maasut!
The code is correct, but let me note, that instead of #hidden_id you need to place the exact ID of the select box field (e.g. #wdform_2_element3).
You can get it from the front-end of your form, by inspecting the element.
The URL will be generated as the following:
http://www.mywebpage.com/?fieldname=value
Let me know in case you have questions.
Cheers!

// Occurs before the form is loaded
function before_load() {
value = getParameterByName('field');
jQuery("#wdform_5_element54").val(value);
}
// Occurs just before submitting the form
function before_submit() {
// IMPORTANT! If you want to interrupt (stop) the submitting of the form, this function should return true. You don't need to return any value if you don't want to stop the submission.
}
// Occurs just before resetting the form
function before_reset() {
}
function getParameterByName(name, url) {
if (!url) {
url = window.location.href;
}
name = name.replace(/[\[\]]/g, "\\$&");
var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),

When I use the http://www.mywebpage.com/?fieldname=value the dropdown field are empty.
Hi, @maasut!
Sorry, that’s my mistake. Since the name of the parameter in the following line is field:
value = getParameterByName('field');
You will need to have the URL with the following format:
http://www.mywebpage.com/?field=value
Or you can set it to any text, but these two strings need to match. Hope this helps.
Cheers!

Hey, @maasut!
That’s a little strange, could we have a look at this problem? Please contact our team through this form and send the link to this forum thread.
Our development team will check the issue as soon as possible, and we’ll share the solution here as well.
Thanks! Have a good day!
Hi, @maasut!
I am happy to inform you, that our development team has resolved the problem on your website. They have commented the following part in Form Options > Javascript:
value = getParameterByName("field");
jQuery("#wdform_5_element54").val(value);
and added the code below to /form-maker/frontend/views/FMViewForm_maker.php instead:
jQuery(document).ready(function () {
value = getParameterByName("field");
jQuery("#wdform_5_element54").val(value);
}
Could you have a look? Please test and confirm if the problem is fixed.
Thank you! Have a great day!
