[Resolved] Saving Cred Generic Fields Data & Accessing IT

[Author]

I have a cpt called Wizard Sections and essentially what I’m trying to do is have a Cred form be populated by these cpt posts(into checkbox grouped by the category they are in), and then be able to output the submissions on the front-end for users. The form is working, now I'm not sure how to access the data and then output it into a template.

So far I’ve put a view into a Cred form that is outputting generic fields:

This is the View in the Cred form:

 <wpv-loop>   
          <h3 style="clear: both;">[wpv-taxonomy-title]</h3>
          [cred_generic_field field='[wpv-taxonomy-slug]' type='checkboxes' class='' urlparam='']
{
"required":0,
"validate_format":0,
"default":[],
"options":[
[wpv-view name="website-wizard-view-1" wpvwizardelementcategory="[wpv-taxonomy-slug]"]]
}
[/cred_generic_field]

And the view in that view that is creating the options is:

<!-- wpv-loop-start --><wpv-loop>[wpv-item index=1]{"value":"[wpv-post-id]","label":"<img src=[types field='element-image' size='medium' url='true' resize='crop'][/types] >"}[wpv-item index=other] ,{"value":"[wpv-post-id]","label":"<img src=[types field='element-image' size='medium' url='true' resize='crop'][/types] >"}</wpv-loop><!-- wpv-loop-end -->

This is working and the form is rendering fine.

But now I’m not sure how to access the submitted data so that I can put it into a template to show the user. I’ve created a custom field with the name faqs-element, the same name as one of the Cred fields, and I’ve tried this code, but it’s not working:

add_action('cred_save_data', 'custom_function',10,2);
function custom_function($post_id, $form_data)
{
    // if a specific form
    if ($form_data['id']==1758)
      
    {
        $field= $_POST["faqs-element[]"];

     update_post_meta($post_id, 'wpcf-faqs-element[]', $field);      
  }
}

Thanks for your assistance,

Tim

Hi, assuming this is a "create new post" CRED form, you should get rid of the array notation "[]" and just use the field slugs. In the $_POST array, you can access it without the wpcf- prefix. When you store the value in the DB, the wpcf- prefix is required. For each item selected, you will add a non-unique row into the post meta table that matches the value selected:

add_action('cred_save_data', 'custom_function',10,2);
function custom_function($post_id, $form_data)
{
    // if a specific form
    if ($form_data['id']==1758)
       
    {
        $vals= isset( $_POST["faqs-element"] ) ? $_POST["faqs-element"] : array();
        foreach($vals as $val) {
          add_post_meta($post_id, 'wpcf-faqs-element', $val, false);
        }      
    }
}

Let me know if you have any additional questions about that.

Hi Chris,

Thank you. And yes it is a Create New Post form. I'm not too swift with php but I think I get the gist of the code you suggested and added it to functions.php. But now how do I know it's being saved? And how do I use the saved data in a views template?

[Christian Cox]

But now how do I know it's being saved?
You'll know it's being saved by checking in wp-admin. Edit the post that gets created by CRED. It will include the faqs element custom field, which should be populated with whatever values were selected in the generic field in your CRED form. If that's not happening, there's a problem we need to investigate further.

And how do I use the saved data in a views template?
Since you'll be saving the data in a custom field, you'll access that just like any other custom field within a Content Template. Click the "Fields and Views" button above the editor area to insert the field using our standard GUI system, or insert the field manually as described here:
https://toolset.com/documentation/customizing-sites-using-php/functions/
On the left side, select the custom field type you chose when you created the faqs-element custom field in Types. Then click the orange +More button underneath the description to see some examples.

Oh, sorry, I didn't explain myself clearly. Yes, I do know how to output standard types fields. I thought this was saving it somewhere else that I needed to hook into. I did create a custom checkboxes field called faqs-element but it is still not saving anything to that.

Hi Timothy,

As Christian is currently on vacation, I have been assigned to handle his queue.

From your last post you said you were not sure how to display the information from the field in your last post correct?

Please let me know.
Thanks,
Shane

[Timothy]

Hi Shane. Outputting toolset custom fields I do all the time, but I don't know how to get the generic field to save to the custom field.

Tim

[Shane]

Hi Timothy,

Try adding persist:1 , to your generic field.

Thanks,
Shane

[Timothy]

I added that but it still does not work.

Hi Timothy,

I took another look at the website and noticed that you didnt have custom fields enabled for your CPT.

Once i've enabled custom fields you should see the generic fields data showing up on the backend now.

Thanks,
Shane

[Timothy]

Oh, I see. I thought it would be actually selecting checkboxes in the custom field on that cpt, didn't know it used WordPress custom fields. So now the issue is displaying the information. I've tried to use both these in a template to output the field but it's not yet working:

[[types field='faqs-element' option='0'][/types][types field='faqs-element' option='1'][/types][types field='faqs-element' option='2'][/types][types field='faqs-element' option='3'][/types]faqs-element]

[types field='faqs-element' separator=', '][/types]

The values this custom field is saving are the post IDs of the cpt that the generic field outputs in checkboxes (which are images). I'd like to get these images to output on the template.

Hi Timothy,

The issue here now is that the types shortcode would only work with custom fields created using Types. In your case you will need to use this shortcode below.

Please let me know if this helps.
Thanks,

I've figured out how to output the image from the selected post, but it seems that it will only output the first selection. As this is a checkbox field multiple entries are being saved, but I'm not sure how to output those multiple entries.

This outputs the first one:
[types field='element-image' alt='%%ALT%%' title='%%TITLE%%' size='medium' align='none' resize='crop' id='[types field='faqs-element' output='raw'][/types]

I tried this to loop through and output multiple selections but it's not yet working:
<wpv-loop>
[wpv-for-each field="wpcf-faqs-element"]

[types field='faqs-element' separator=', '][/types]

</wpv-loop>

[Shane]

Hi Timothy,

The [wpv-for-each field="wpcf-faqs-element"] statement only works if the element is a repeated field.

The faqs-element field was created in Types as a checkbox field correct?

I'm a bit confused as to if this field is a Types created field or if its a field created using CRED.

Please let me know.
Thanks,
Shane

Hi Shane,

It's a generic field created using CRED. I originally thought if I also create a types custom field with the same name that the generic field would save to the types field. Now I see that it saves the generic field to wordpress custom fields, which is fine as long as I can access all the selected options via a template to output them on the front-end. Will that be possible?
