I am currently displaying javascript via PHP echo:
echo 'var currentInvoiceDataJSON = <?php echo json_encode($yearData_Invoices[$currentYear] ); ?>;';
However I get a Uncaught SyntaxError: Unexpected token < error which I infer is related to the second
How can I get this resolved and there any other possibilities?
Some expert advise would be appreciated.
That code ends as invalid Javascript code.
Here's what happens:
Your server echoes a string:
echo 'var currentInvoiceDataJSON = <?php echo json_encode($yearData_Invoices[$currentYear] ); ?>;';
Your browser now has:
var currentInvoiceDataJSON = <?php echo json_encode($yearData_Invoices[$currentYear] ); ?>;
Once your PHP script finishes running and echoes that first string, PHP cannot process the inner echo.
What I would do:
$data = json_encode($yearData_Invoices[$currentYear]);
echo 'var currentInvoiceDataJSON = ' . $data . ';';
Do this instead:
echo 'var currentInvoiceDataJSON = '.<?php echo json_encode($yearData_Invoices[$currentYear] ); ?>.';';
I have not tested this but give it a try:
echo "var currentInvoiceDataJSON = '".str_replace("'","\\'",json_encode($yearData_Invoices[$currentYear]))."';";
just change to
echo "var currentInvoiceDataJSON = ".json_encode($yearData_Invoices[$currentYear] ).";";
and also be aware that single quoted strings in php don't interpolate variables so
$a = "Hello World";
echo '$a'; // outputs : $a
echo "$a"; // outputs : Hello World
and when you are in a php context
