Blocks

"Words Counter" inserts a javascript block with the wordsCounter routine:

wordsCounter(text);

• text: Text to check.

Example:

wordsCounter("Lorem ipsum");

Output: 2

The block includes the xe_open_exchange_rates operation whose parameter is a plain object with the following properties:

• from: a three letters currency code. For example: USD (required)
• to: a three letters currency code. For example: GBP (required)
• field: a valid jQuery selector of an input tag for assigning the exchange rate. For example, if you are using the calculated fields form plugin, and you want to assign the exchange rate to the fieldname1 field, the selector would be: [id*="fieldname1_"] (optional)
• callback: a function that will receive as parameter an object with all currencies codes and the corresponding exchange rates. For example: function(rates){alert(rates['EUR']);} (optional)
• url: the URL to the public website. In cases where the URL to the public website and the WordPress are different, might be require pass to the block the URL to the public website (optional)

Example:

xe_open_exchange_rates({'from': 'USD', 'to': 'EUR', 'field': '[id*="fieldname'+'1_"]'});

A specific example: Assuming there is a field in the form that calculate a service price in United State Dollars (USD), the fieldname1, and you want get the price in Euros (EUR), furthermore there is a hidde field for the exchange rate, the fieldname2. The equation to associate with the calculated field to calculate the price in Euros would be:

(function(){
xe_open_exchange_rates({'from': 'USD', 'to': 'EUR', 'field': '[id*="fieldname'+'2_"]'});
return fieldname1*fieldname2;
})()

If there is a dropdown field for selecting the currency code, the fieldname3, the equation would be:

(function(){
xe_open_exchange_rates({'from': 'USD', 'to': fieldname3, 'field': '[id*="fieldname'+'2_"]'});
return fieldname1*fieldname2;
})()

The "Javascript Unserializer" inserts a javascript block with the unserialize routine:

unserialize(phptext);

• phptext: Serialized PHP Object.

Examples:

unserialize('O:8:"stdClass":2:{s:5:"attr1";s:15:"First Attribute";s:5:"attr2";s:16:"Second Attribute";}');

Output would be a javascript object with the structure:

{attr1:"First Attribute", attr2:"Second Attribute"}

The block reads the exchange rates from the Currency Converter API website
