I want to pass a variable that is in php to JavaScript. For example this:
<?php
$color = "Red";
?>
<script type="text/javascript">
var color = <?php $color ?>;
alert("color: " + color);
</script>
I tried this code, but it does not work.
I see three problems:
Then there will have to be quotes:
var color = "codigo_da_côr";
^ ^
;
A ; is missing after the PHP variable, it should be:
<?php $color; ?>
^
As Jader noted correctly, it is still necessary to echo the variable ...
You can <?=$color;?> if you do not want to use echo (shortcut), or you must have echo so <?php echo $color; ?>
var color = "<?php echo $color; ?>";
