Q:

wordpress - Get Gravity Forms Input Value, store as variable in functions.php

Hey everyone,

I hope you're doing well. I have a question regarding Gravity Forms in WordPress.

So, I have a form created with Gravity Forms on my website and I want to retrieve the input value of a specific field and store it as a variable in my functions.php file. This value will then be used for some custom functionality on my site.

Can anyone guide me on how I can achieve this? Any help would be greatly appreciated.

Thanks!

Hey there,

I recently faced a similar situation where I needed to retrieve the input value from a Gravity Forms field and store it as a variable in my functions.php file. Here's what worked for me:

First, you need to determine the form ID and the field ID you want to retrieve the value from. You can find these IDs by inspecting the HTML of your form.

Once you have the IDs, you can use the `gform_field_value_$form_id` filter hook to retrieve the input value. In your case, you would replace `$form_id` with your actual form ID.

Here's an example of how you can make use of this filter in your functions.php:

php
function get_gravity_forms_input_value( $value, $lead, $field, $form ) {
// Replace '3' with your form ID
if ( $form['id'] === 3 && $field['id'] === 4 ) { // Replace '4' with your field ID
$my_variable = $value; // This will store the input value as a variable
}
return $value;
}
add_filter( 'gform_field_value_$form_id', 'get_gravity_forms_input_value', 10, 4 );


In the above code, `$my_variable` will hold the value of the input field with the ID `4` from the form with the ID `3`. Make sure to replace these IDs with your actual IDs.

Remember to save the functions.php file and test it out by submitting the form to see if the value is being captured correctly.

I hope this helps! Let me know if you have any further questions.

Hey,

I understand your frustration and I've been in a similar situation with Gravity Forms and retrieving input values. Here's another approach that might work for you:

Instead of using the `gform_field_value_$form_id` filter, you can utilize the `gform_pre_submission` hook to capture the input value before the form is submitted.

Here's an example of how you can achieve this in your functions.php:

php
function store_gravity_forms_input_value( $form ) {
// Replace '3' with your form ID
if ( $form['id'] === 3 ) {
parse_str( $_POST['input_4'], $input_value ); // Replace '4' with your field ID
$my_variable = $input_value['input_4']; // This will store the input value as a variable
}
}
add_action( 'gform_pre_submission', 'store_gravity_forms_input_value' );


In the above code, `$my_variable` will hold the value of the input field with the ID `4` from the form with the ID `3`. Again, make sure to replace these IDs with your actual IDs.

Remember to save the functions.php file and give it a go by submitting the form to see if the value is being stored correctly.

I hope this alternative approach helps! Let me know if you have any further questions or need more assistance.
