Answer 1

you can create you own module that contains a translation file i18n/en_US.csv with this content:

"-- Please Select --","Please Select"

• Arun Karnawat: Ya, I thought that but now, I want to do something Like this insted of Please Select I want Select Size, Select Color So I have to override the view block.
• Marius: that is a totally different questions. please don't mix them.
• Arun Karnawat: I followed you advice and create a new question for it magento.stackexchange.com/questions/131762/…

Answer 2

need to override the below block

<magento-root>/vendor/magento/module-catalog/Block/Product/View/Options/Type/Select.php

in the above file change the below line

 $select->setName('options[' . $_option->getid() . ']')->addOption('', __('-- Please Select --')); 

TO

 $select->setName('options[' . $_option->getid() . ']')->addOption('', __('Please Select'));

for override the block refer this answer

note: I am not tested but I hope it works

• Arun Karnawat: Hi, I have done the same. I have override the Magento\Catalog\Block\Product\View\Options\Type\Select Block in my module, but doing so, Removed the select box from the view as in the above image[Refer Question]
• Arun Karnawat: Do I have to override template file as well in the module vendor\magento\module-catalog\view\frontend\templates\product\view\options\type\select.phtml
• Bilal Usean: for trial just directly change the text in vendor/magento/module-catalog/Block/Product/View/Options/Type/Select.php. after that clear cache then load page. If it worked, definitely you make mistake in override.

Answer 3

given that Marius' solution is likely the most effective one, I take the chance to offer an alternative to avoid block rewrite. It is based on the usage of a plugin.

Assuming you know how to define your own module, you can declare the plugin in the <your_module_dir>/etc/di.xml file as follows:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <type name="Magento\Framework\View\Element\Html\Select">
 <plugin name="vendorname_view_element_html_select"
 type="VendorName\ModuleName\Plugin\View\Element\Html\SelectPlugin" />
 </type>
</config>

Note: change VendorName and ModuleName according to your needs.

Then define the plugin in <your_module_dir>/Plugin/View/Element/Html/SelectPlugin.php:

<?php
namespace VendorName\ModuleName\Plugin\View\Element\Html;
class SelectPlugin
{
 public function beforeAddOption($subject, $value, $label) 
 {
 if ($value == '') {
 $label = __("Whatever you want");
 }
 return [$value, $label];
 }
}

Hope it helps.
