I am trying to save multi select value in DB. But getting error Array to string conversion in

/var/www/html/devstore/vendor/magento/framework/DB/Adapter/Pdo/Mysql.php on line 2999

Template file code -

<div class="field profile">
                <label for="sell_country"> <?php echo __('Sell in Countries') ?> </label>
                <?php
                if($profile_hint_status && $helper->getProfileHintCountry()){?>
                    <img src="<?php echo $this->getViewFileUrl('Webkul_Marketplace::images/quest.png'); ?>" class='questimg' title="<?php echo $helper->getProfileHintCountry() ?>"/>
                <?php
                } ?>
                <div class="control">
                     <select name="sell_country[]" id="sell_country" multiple="multiple">
                        <option value="" selected="selected" disabled="disabled"><?php echo __('Select Country')?></option>
                    <?php foreach($block->getCountryOptionArray() as $country){?>
                        <option <?php
                        if($country['value']!=''){
                        echo ($partner['country_pic']==$country['value']?"selected='selected'":""); ?>value="<?php echo $country['value']; ?>"><?php echo $country['label']; ?></option>
                    <?php 
                      }
                    }   ?>
                    </select>

                </div>
            </div>

In controller file -
if (array_key_exists('sell_country', $fields)) {
                        $value->setCountryPic(implode(',', $fields['sell_country']);
                    }
                    $value->save();

  • can you provide a little more code from your controller? what is your $value object and what data does it contain beside the 'country_pic' you add manually?

  • @HelgeB $value = $this->_objectManager->create( 'Webkul\Marketplace\Model\Seller' )->load($autoId); This is $value, I am customizing webkul marketplace extension to save multiselect product selling countries vendor attribute.

  • ok, if you have only the 4 lines in your controller affecting the $value object and no other values it's really strange. In this case I would suggest to dump the data of the value object and see what's in there.

  • @HelgeB please check the controller above.

Your error comes from the following line

$value->addData($fields);

Here you add all the data you get from your form inlcuding the array. Anyway I don't see the implode in your controller. Put the code

 if (array_key_exists('sell_country', $fields)) {
     $value->setCountryPic(implode(',', $fields['sell_country']);
     unset($fields['sell_country']);
 }

before that line and that should work.

Please notice that you save the $value model twice and you also use the variable $value in other context in the code. That works but it's not really a good practice :-)

  • Hi @HelgeB Thankyou for your response but, After adding the above code i still got error -Notice: Array to string conversion

  • Can you please dump the data of the value object just before the save call? Then we can see, which array is still in your data
    – HelgeB

  • Hi, when we use array in html it is not dumping data, but for single value I dump and this is the output - string(2) "AL" .
    – chanchal
    Feb 11, 2019 at 4:49
  • I printed the value print_r($fields); and got this output- Array ( [form_key] => pYm9J1Kr5Ddx2H0g [twitter_id] => [facebook_id] => [instagram_id] => [gplus_id] => [youtube_id] => [vimeo_id] => [pinterest_id] => [contact_number] => [taxvat] => [background_width] => [return_policy] => [shipping_policy] => [country_pic] => AX [sell_country] => Array ( [0] => AW [1] => BM [2] => BT [3] => BO [4] => BA ) )

    Feb 11, 2019 at 5:21
  • Ok, that should work if you unset the sell_country key before you call addData($fields). Can you please update your question with the actual code? Please dump also $value->getData() just before calling the save() method.

I did almost like this one before and it worked for me.

Before set data in model I used implode like:

if(isset($data['country_pic'])){
    $data['country_pic']=implode(',',$data['country_pic']);
}

$model->setData($data);

  • I did if (array_key_exists('sell_country', $fields)) { $fields['sell_country'] = implode(',', $fields['sell_country']); $value->setCountryPic($fields); } $value->save(); and this both if (array_key_exists('sell_country', $fields)) { $fields['sell_country'] = implode(',', $fields['sell_country']); $value->setCountryPic($fields['sell_country']); } $value->save();
