What I want is for my php variable to get the value of my javascript variable
So I get my javascript value:
(function() {
var variable="contenido";
alert(variable);
})();
</script>
So I want to pass it to my php variable:
$url = "<script> document.write(variable) </script>";
echo 'variablePHP = '.$url;
The problem occurs because your variable is not global, so php can not find it, you must declare your variable globally. I share an example of passing values through cookies.
<script>
var variable = "";
(function() {
this.variable="contenido";
alert(this.variable);
})();
/*Ejemplo mediante cookiees*/
document.cookie = "lastname=Martinez";
</script>
<?php
$url = "<script> document.write(variable) </script>";
echo 'variablePHP = '.$url;
/*Ejemplo mediante cookies*/
$last_name = $_COOKIE['lastname'];
echo "Apellido".$last_name;
?>
