But in my case i have a custom field to manipulate. </p> https://legacy.forums.gravityhelp.com/topic/change-custom-field-multi-select-output-to-work-with-advanced-custom-fields#post-57665 Thu, 03 May 2012 17:01:07 +0000 Alex Cancado 57665@https://legacy.forums.gravityhelp.com/ <p>Yea, I see the issue. The string is getting serialized again. The problem is that the extra serialization is coming from WordPress. What I would suggest is that you use the gform_post_data filter instead. This filter you will give you total control on how the post is created and you can manipulate the data to fit your needs.<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_post_data" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_post_data</a> </p> https://legacy.forums.gravityhelp.com/topic/change-custom-field-multi-select-output-to-work-with-advanced-custom-fields#post-57547 Thu, 03 May 2012 04:13:59 +0000 schnettker 57547@https://legacy.forums.gravityhelp.com/ <p>Sorry for my bad english. It seems you don't understand my Problem.</p> <p>If i chose checkboxes the gravity forms stores (if 2 checkboxes checked) the value like<br /> name_of_field value_1<br /> name_of_field value_2</p> <p>2 rows</p> <p>That is not nice but as david told i can fix it with gform_pre_submission_filter. Look at my code above - i did it allready! I create allready the wanted value (a:2:{i:0;s:4:"ipad";i:1;s:6:"iphone";} ) and in the mail i see that value (trailing after a dot). </p> <p>But when i look in the database, then i found a<br /> s:35:"a:2:{i:0;s:4:"ipad";i:1;s:6:"iphone";}";</p> <p>That is the serialized value of my wanted result. I don't understand why gravity form serialize that again!? If gravity form want a serialzied value, then why saving 2 rows? My data is perfectly in line 7 on my example above - but stored is another value </p> https://legacy.forums.gravityhelp.com/topic/change-custom-field-multi-select-output-to-work-with-advanced-custom-fields#post-57516 Wed, 02 May 2012 18:26:00 +0000 Carl Hancock 57516@https://legacy.forums.gravityhelp.com/ <p>Gravity Forms stores custom field data this way when handling multi-value field types because it's a standard way of storing custom field data in WordPress. </p> <p>You store multiple custom field values, using the same custom field key, and then you can pull all of them in to display them in your theme template by looking through the values that are pulled together as an array using built in WordPress functions.</p> <p>I understand you are unhappy with the situation, but the way Gravity Forms is doing things is not wrong or incorrect. It's just that as with anything there are a variety of ways to accomplish the same thing. Gravity Forms does it this way, ACF chose to do it another way. </p> <p>What we can do is look into adding a hook to Gravity Forms that can be used to tell Gravity Forms to store the values as an array in a single custom field rather than as multiple custom fields. I'll pass this along to our lead developer to see if this is something we can have implemented.</p> <p>In the mean time, what David suggested is definitely one way you can handle this. If you need to store the values in a specific format so another plugin you are using can work with it, then you can do this by using the gform_pre_submission hook to manipulate the data.</p> <p>Gravity Forms itself stores data in a serialized format, so there could be some added complexity going on here that you could be encountering.</p> <p>I am going to forward this to our lead developer who will take a look at what you are doing and respond to you with some suggestions. </p> https://legacy.forums.gravityhelp.com/topic/change-custom-field-multi-select-output-to-work-with-advanced-custom-fields#post-57344 Wed, 02 May 2012 07:58:18 +0000 schnettker 57344@https://legacy.forums.gravityhelp.com/ <p>if i look in the backend form and the notification email then i found the expected result. </p> <p>a:2:{i:0;s:4:"ipad";i:1;s:6:"iphone";}</p> <p>Why modify gravity form a serialized string again? </p> https://legacy.forums.gravityhelp.com/topic/change-custom-field-multi-select-output-to-work-with-advanced-custom-fields#post-56943 Mon, 30 Apr 2012 05:09:51 +0000 schnettker 56943@https://legacy.forums.gravityhelp.com/ <p>Okay, it nearly works .... but ...<br /> <pre><code>add_filter(&quot;gform_pre_submission_filter_1&quot;, &quot;ser_preise&quot;); function ser_preise($form){ /// some code $preise=maybe_serialize($preise); $_POST[&quot;input_7_1&quot;] = $preise; //Echo the array echo $preise; return $form;</code></pre> <p>The Echo shows me the right result (a:2:{i:0;s:4:"ipad";i:1;s:6:"iphone";}) , but in database the result is</p> <p>s:35:"a:2:{i:0;s:4:"ipad";i:1;s:6:"iphone";}";</p> <p>It seems there is another "serialize" on the data </p>
