Help to insert content into post custom fields

You’ll need to look at how we’re storing the custom fields. Basically every metabox is a serialized array with the fields inside it

This is how that array might look like:

Array
(
    [0] => Array
        (
            [birth-day] => 2014-04-17
            [editor] => Extra info baby
            [avatar] => 51
        )

)

As long as you keep the same structure of the array, cpt’s published from the front-end will be able to modify them in the backend using WCK.

Hi, Thanks for answer.

I couldn’t get the solution with the information you give me. There could be something wrong in my code, Could you tell me what’s the mistake i’m doing?

I’m using two metabox (Specific Details and Basic Details) with two fields inside(address and extra-info)(phone and email) respectively.

This is my code:

if( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) &&  $_POST['action'] == "new_post") {

    if (isset ($_POST['title'])) {
        $title =  $_POST['title'];
    } else {
        echo 'Please, Complete Title Field';
    }

    $tags = $_POST['post_tags'];
    $address = $_POST['address'];
    $extra_details = $_POST['exinfo'];

    $phone= $_POST['phone'];
    $email = $_POST['email'];

    $new_post = array(
    'post_title'    =>  $title,
    'post_content'  =>  $description,
    'post_tags'     =>  array($_POST['country']),
    'post_tags'     =>  array($_POST['city']),
    'tags_input'    =>  array($tags),
    'post_status'   =>  'publish',
    'post_type' =>  'events'
    );

    $pid = wp_insert_post($new_post);
    update_post_meta($pid, 'specific-details_address_1', array( $address ) );
    update_post_meta($pid, 'specific-details_extra-info_1', array( $extra_details ) );

    update_post_meta($pid, 'basic-details_phone-number_1', array( $phone) );
    update_post_meta($pid, 'basic-details_email_1', array( $email ) );

    if ($_FILES) {
        foreach ($_FILES as $file => $array) {
        $newupload = insert_attachment($file,$pid);
        }
    }

    wp_set_post_tags($pid, $_POST['post_tags']);
    wp_set_post_terms( $pid, $_POST['country'], 'tax-country', false );
    wp_set_post_terms( $pid, $_POST['city'], 'tax-city', false );

}

do_action('wp_insert_post', 'wp_insert_post');

And this is my code in the form

<form id="new_post_event" name="new_post" method="post" action="" class="event-entry" enctype="multipart/form-data">
            <div id="fe-block1" class="fe-block">
                <fieldset name="name">
                    <label for="title">Title*:</label><br>
                    <input type="text" id="title" value="" tabindex="1" name="title" />
                </fieldset>
            </div>
            <div id="fe-block2" class="fe-block">
                <fieldset class="country">
                    <label for="country">Country:</label><br>
                    <?php wp_dropdown_categories(array('hide_empty' => 0, 'hide_if_empty' => false, 'name' => 'country', 'orderby' => 'name', 'taxonomy' => 'country', 'selected' => $tag->parent, 'exclude_tree' => $tag->term_id, 'hierarchical' => true)); ?>
                </fieldset>
                <fieldset class="city">
                    <label for="city">City:</label><br>
                    <?php wp_dropdown_categories(array('hide_empty' => 0, 'hide_if_empty' => false, 'name' => 'city', 'orderby' => 'name', 'taxonomy' => 'city', 'selected' => $tag->parent, 'exclude_tree' => $tag->term_id, 'hierarchical' => true)); ?>
                </fieldset>
                <fieldset name="address">
                    <label for="address">Address:</label><br>
                    <input type="text" id="address" value="" tabindex="13" name="address" />
                </fieldset>
                <fieldset name="phone">
                    <label for="phone">Phone:</label><br>
                    <input type="text" id="phone" value="" tabindex="13" name="phone" />
                </fieldset>
                <fieldset name="email">
                    <label for="email">Email:</label><br>
                    <input type="text" id="email" value="" tabindex="13" name="email" />
                </fieldset>
                <fieldset name="exinfo">
                    <label for="exinfo">Inf Details(max. 200 caract.):</label><br>
                    <textarea type="text" id="exinfo" value="" tabindex="26" name="exinfo"></textarea>
                </fieldset>
                <div class="submit">
                    <input type="submit" value="Send" tabindex="40" id="submit" name="submit" />
                </div>
                <input type="hidden" name="action" value="new_post" />
                <?php wp_nonce_field( 'new-post' ); ?>
            </div>
        </form>

All this code is in the same file front-form.php

In functions.php I put this code:

add_filter( 'wck_cfc_unserialize_fields_basic-events-details', 'wck_change_unserialize_arg' );
function wck_change_unserialize_arg( $bool ){
return true;
}

add_filter( 'wck_cfc_unserialize_fields_specific-events-details', 'wck_change_unserialize_arg_2' );
function wck_change_unserialize_arg_2( $bool2 ){
return true;
}

I hope you could help me to understand whats wrong with the code? I’m using The Custom Field creator from the wck plugin

Thanks

Hi,

Yup, I know why this doesn’t work. Unfortunately the unserialized filter only works one way.

We you activate unserialized fields on a particular metabox, all it dose is to ALSO save those fields in normal fields. This means that when you edit them, WCK doesn’t know about those changes because he’s only looking in the serialized meta field.

That being said, instead of updating fields one by one, you’ll need to create an array and insert that:

update_post_meta($pid, 'specific-details', $custom_array_with_post_data );

Where $custom_array_with_post_data has the same information as an array built with the metabox in the backend.

If you’re not sure what’s the structure, fill a metabox in the backend, then in the single.php do a var_dump after
‘get_post_meta($post->ID, ‘specific-details’, true);’

Hope this helps!
