Using a PHP variable in Javascript code

Question

Can I please have some help in using a PHP variable in some Javascript code.

I am wanting to pass a value to a Javascript function that is stored in a PHP variable.

Here is my code:

$UpdateText="updateReTotal(Tills,'pos_cash','{$till->till_id}');updateVariance('{$till->till_id}')";
echo '<script type="text/javascript">'
 , 'testFunctionForUpdateTotal(.$UpdateText.);'
 , '</script>';

Thanks in advance.

Answer 1

$UpdateText="updateReTotal(Tills,'pos_cash','{$till->till_id}');updateVariance('{$till->till_id}')";
echo '<script type="text/javascript">'
 . 'testFunctionForUpdateTotal('.$UpdateText.');'
 . '</script>';

Your code would have worked if you were using double quotes (except for the two dots beside your variable, plus you need to escape the other double quotes), like this:

echo "<script type=\"text/javascript\">
 testFunctionForUpdateTotal($UpdateText)
 </script>";

But this does not work with single quotes.

<script language='javascript'>
function show(j)
{
alert(j);
}
</script>
<?php
$v = "a";
echo "<div onclick=\"show('".$v."',);return false;\">CLICK</div>";
?>
