如果有标题，如何在PHP中使用javascript？

Question

if(($row["status"])!="valid")
{
    $stats=$row["status"];
    echo "<script type='text/javascript'>";
    echo "alert('Your Status is $stats..Please Try Again Later...');";
    echo "</script>";
    header ("location: index.php");
}

it is a part of a php code. if i use // before header, javascript run..but when i don't use // , it goes to directly index.php. what is the solution?? OR is there is any way that i can call a javascript function for showing a message from this if condition??

Answer 1

In this scenario, Replace header with document.location.href So you can display an alertbox and when you click ok it redirects to your index.php page

if(($row["status"])!="valid")
{
    $stats=$row["status"];
    echo "<script type='text/javascript'>";
    echo "alert('Your Status is $stats..Please Try Again Later...');";
    echo "</script>";
    echo "<script>document.location.href='index.php'</script>";
}
