Params::setParam- meta

[WEBmods]

So you can't use posted_item as it runs when all data is already saved in the database. I will check if we can modify meta value saved in session with pre_item_post.

Thank you!

According to my quick research, this should work...

Code: [Select]

<?php
function wm_item_pre_post_session_edit() {
    $key = 10; // Your meta field ID.
    $meta = Params::getParam('meta'); // Get all meta fields.
    if(@$meta[$key] == null) return; // Stop the function if your specific meta field doesn't exist. @ is added to stop warnings if $meta is not an array.
    $old_value = $meta[$key]; // Get value from your meta field.
    $new_value = 'New value'; // Put new value for your meta field.

    Session::newInstance()->_setForm('meta_'.$key, $new_value); // Save new value.
    Session::newInstance()->_keepForm('meta_'.$key);
}
osc_add_hook('pre_item_post', 'wm_item_pre_post_session_edit');

thank you very much for the code but i exactly paste this code in my functions.php and changed the 10 to my custom-filed id (oc_t_meta_fields -> pk_i_id), but after publishing the item, its value did NOT change to 'New value'

I did more research and I think there is no other way but to update the database or to change core files. I used both Session and Param classes to try to modify meta, but I noticed that meta fields are already saved in a variable when pre_item_post runs.

ItemActions.php:149

Code: [Select]

            $meta = Params::getParam("meta"); // META IS SET HERE.
            foreach($_meta as $_m) {
                $meta[$_m['pk_i_id']] = (isset($meta[$_m['pk_i_id']]))?$meta[$_m['pk_i_id']]:'';
            }
            if($meta!='' && count($meta)>0) {
                $mField = Field::newInstance();
                foreach($meta as $k => $v) {
                    if($v=='') {
                        $field = $mField->findByPrimaryKey($k);
                        if($field['b_required']==1) {
                            $flash_error .= sprintf(_m("%s field is required."), $field['s_name']) . PHP_EOL;
                        }
                    }
                }
            }
            // hook pre add or edit
            // DEPRECATED: pre_item_post will be removed in 3.4
            osc_run_hook('pre_item_post'); // CHANGING PARAM OR SESSION HERE DOES NOT AFFECT ANYTHING.
