Hi guys,

I've created a custom field of the "textarea" type and "item" table. Now is it possible to somehow count (may be with $count = str_word_count($_POST) and echo/display to the customer in the cart how many words he has entered into this field?

The counting doesn't have to occur on the fly, as the customer enters his text, but it does have to eventually, after he entered his text, be shown to my customer before he selects the number of the product that he is purchasing.

Cheers,

Alex

Hi,

Not really, but something similar is possible with the options available. Simply enter the maximum characters limit you want in the "Maximum length" field of your custom field and it will display the user how much characters is left while he types.
If you really wants to display the number of characters he typed, it would require custom code. If you want to do in in the cart display on the checkout, you can edit the file "cart" of the view "checkout" via the menu Display>Views and add your code next to the display of the custom fields.

Did I pick up the right snippet?
<div class="hikashop_cart_product_custom_item_fields">
                <?php
                if(hikashop_level(2) && !empty($this->extraFields['item'])){
                  foreach($this->extraFields['item'] as $field){
                    $namekey = $field->field_namekey;
                    if(empty($row->$namekey) && !strlen($row->$namekey)) continue;
                    echo '<p class="hikashop_cart_item_'.$namekey.'">'.$this->fieldsClass->getFieldName($field).': '.$this->fieldsClass->show($field,$row->$namekey).'</p>';
                  }
                }
                $input='';
                if($group){
                  foreach($this->rows as $j => $optionElement){
                    if($optionElement->cart_product_option_parent_id != $row->cart_product_id) continue;
                    if(!empty($optionElement->prices[0])){
                      if(!isset($row->prices[0])){
                        $row->prices[0]->price_value=0;
                        $row->prices[0]->price_value_with_tax=0;
                        $row->prices[0]->price_currency_id = hikashop_getCurrency();
                      }
                      foreach(get_object_vars($row->prices[0]) as $key => $value){
                        if(is_object($value)){
                          foreach(get_object_vars($value) as $key2 => $var2){
                            if(strpos($key2,'price_value')!==false) $row->prices[0]->$key->$key2 +=@$optionElement->prices[0]->$key->$key2;
                          }
                        }else{
                          if(strpos($key,'price_value')!==false) $row->prices[0]->$key+=@$optionElement->prices[0]->$key;
                        }
                      }
                    }
                     ?>
                      <p class="hikashop_cart_option_name">
                        <?php
                          echo $optionElement->product_name;
                          if(@$optionElement->prices[0]->price_value_with_tax>0){
                            echo ' ( + ';
                            $this->row=&$optionElement;
                            $this->unit=true;
                            echo strip_tags($this->loadTemplate()).' )';
                          }
                        ?>
                      </p>
                    <?php
                    $input .='document.getElementById(\'product_option_'.$optionElement->cart_product_id.'\').value=qty_field.value;';
                    if(empty($this->disable_modifications)) echo '<input type="hidden" id="product_option_'.$optionElement->cart_product_id.'" name="item['.$optionElement->cart_product_id.']" value="'.$row->cart_product_quantity.'"/>';
                  }
                }?>

Yes.
You'll find the comment text in $row->COLUMN where COLUMN is the column name of your custom field.

I tried (I must admit - I am not a coder)

=======================

<div class="hikashop_cart_product_custom_item_fields">
<?php

echo $row->ticket_text;

.....
===================

where "ticket_text" is the name of the column, but nothing showed up in the cart.

It will only show up if you enter something in the field of course.
Also, you need to do the modification in the cart file of the view checkout (for the checkout) not the view "product" (for the cart module).
Also, you need to do it for the correct frontend template you're using, not another one or you won't see the change.
