Virtuemart Check default Radio Custom field.

The javascript for this is really simple:

radiobtn = document.getElementById("theid"); 
radiobtn.checked = true;

The difficulty will lie in the fact that the id of the element is changing depending on the product. Indeed the product id is used in the radio id.

A convenient option is to use CSS selectors in javascript:


radiobtn =document.querySelector(CSS selectors) .

We want to select the first radio input where the parent is div.controls

radiobtn =document.querySelector(" div.controls> label  > input");  
radiobtn.checked = true;

For good measure we should check that div.controls exists on the page and that we are on a product page.

if(document.querySelector(" div.controls > label  > input")){
   radiobtn = document.querySelector(" div.controls > label  > input");  
   radiobtn.checked = true; 
 }

This query only catch the first radio button custom field. In case we have a second custom field options for our product we need to catch that too. We will use jquery for that purpose to catch the radio button id whatever product page it is set on (remember that the product id is part of the radio button id and that’s the only changing part).

jQuery.noConflict();
jQuery(document).ready(function(){
if (jQuery(“[id$=_885843]”)){
jQuery(“[id$=_885843]”).prop(“checked”,true);
}
});

Repeat the operation for any additional custom fields needed a default check.

WooCommerce: Add Checkout Fees Based on Custom Radio Button

Materialized: Select value not passed in post body

If you are using the materialize framework, you might have trouble to pass a value when using the select element in a form. Indeed the value is not taken into account. To solve this give an id to the select element and and add an hidden input field with the relevant field name and id as so:

<div class="row">             
<div  class="input-field col s12">                 
<select id="data_select">                   
<option  value="" disabled selected>Data</option>                   <option  value="1">data 1</option>                   
<option  value="2">data 2</option>                   
<option  value="3">data 3</option>                   <option  value="4">data 4</option>                 </select>                 
<input type="hidden" name="data_name" id="data_hidden" />             </div>                       
</div>

and with the associated script:

// Post Materialize select value$(document).ready(function() {
     $('#data_select').on('change', function() {
         var data_select=document.getElementById("data_select").value;
         document.getElementById("data_hidden").value=data_select;
        
     });

[Edit: everything worked fine simply using the following code: 

<div class="row">             
<div  class="input-field col s12">                 
<select name="data_name"  id="data_select">                   
<option  value="" disabled selected>Data</option>                   <option  value="1">data 1</option>                   
<option  value="2">data 2</option>                   
<option  value="3">data 3</option>                  
<option  value="4">data 4</option>                 
</select>                 
</div>                       
</div>

WAMP Syntax error in INSERT INTO statement

Error : Syntax error in INSERT INTO statement

You might be using some reserved words as the table name.

Based on that article: https://support.microsoft.com/en-gb/help/892608/you-may-receive-a-syntax-error-in-insert-into-statement-error-message.

I tested by changing the name of the table from “orders” to orders_table and it solved the issue. I conclude that orders might be a reserved word.

Solution: change the table name to something else as illustrated above.

WP Plugins or Themes Update error: “Destination directory for file streaming does not exist or is not writable “

Check in wp-config.php which folder is assigned as the temporary directory. the line will start with

  
define('WP_TEMP_DIR', ABSPATH . '/path/to/temp');

Through ftp check the permission on the folder. It should be 755.

Even if all seems alright the update might still failed. In my case my wp-config.php is placed outside the public directory altogether. I decided to go with a temp folder also place outside of the public directoy, those I had to modify my wp-config.php (which is placed in its dedicated directory) as follow:

. I decided to go with a temp folder also place outside of the public directoy, those I had to modify my wp-config.php (which is placed in its dedicated directory) as follow:

define('WP_TEMP_DIR', ABSPATH . '/../temp/');

The path that was causing the error was as follow: 

define('WP_TEMP_DIR',dirname(FILE).'/wp-content/uploads');

Placing the wp-config.php outside the public directory allow for an extra layer of security in case the php settings of the apache server get messed up and the php files are exposed instead of being executed. Even though this situation SHOULD NOT happen, there is a possibility that it does and that’s what security is about afterall: being prepared for the unlikely events.

Securing wp-config.php

There is a clear case for moving the file out of the public directory: see the following stackexchange thread https://wordpress.stackexchange.com/questions/58391/is-moving-wp-config-outside-the-web-root-really-beneficial

Just move wp-config.php one level up outside the public directory and wordpress will be able to look for it on its own automatically and you’re all set.

If you have installed several wordpress site in different subdomain, the option might not work for you. In that case, follow the instruction below taken directly from the aforementionned stackexchange thread:

How to move wp-config.php to any location on your server

WordPress will automatically look one directory above your WordPress installation for your wp-config.php file, so if that’s where you’ve moved it, you’re done!

But what if you’ve moved it somewhere else? Easy. Create a new wp-config.php in the WordPress directory with the following code:

<?php

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');

/** Location of your WordPress configuration. */
require_once(ABSPATH . '../phpdocs/wp-config.php');

(Be sure to change the above path to the actual path of your relocated wp-config.php file.)

If you run into a problem with open_basedir, just add the new path to the open_basedir directive in your PHP configuration:

open_basedir = "/var/www/vhosts/example.com/httpdocs/;/var/www/vhosts/example.com/phpdocs/;/tmp/"

That’s it!

Use JCH optimize with woocommerce

Issue:

JCH optimize might cause issue with the checkout page with certain payment plugin. A loading circle appear and don’t seem to go away anytime soon.

Solution:

To sort that out simply exclude some files related to the checkout page from optimization in jch optimization dashboard. I have excluded …/assets/css/frontend.css from Exclude these CSS files and our payment plugin css: 
checkout-maksukavat.css in  Exclude CSS files from these plugins
