I have a php file which connects to a MySql db and read the last entry from a specific table. What I am trying to do, is to display(echo) the last entry from the table using a JavaScript popup box into the external html file Below I have the code for the PHP file (which is working fine) and the html one but unfortunately I can't figure out how to pass the PHP variable to JavaScript function.
Many thanks in advance.
The php file would be this one:
<?php
// 1. Create a database connection
$connection = mysql_connect("localhost","root","password");
if (!$connection) {
die("Database connection failed: " . mysql_error());
}
// 2. Select database to use
$db_select = mysql_select_db("manage_projects",$connection);
if (!$db_select) {
die("Database selection failed: " . mysql_error());
}
// 3. Perform database query
$result = mysql_query("SELECT survey_desc FROM subjects ORDER BY id DESC LIMIT 0,1", $connection);
if (!$result) {
die("Database query failed: " . mysql_error());
}
// 4. Use returned data
while ($row = mysql_fetch_array($result)) {
echo $row["survey_desc"]."<br />";
}
// 4.1 Alternative way to use returned data
/* $row = mysql_fetch_array($result);
echo $row["survey_desc"]."<br />";
*/
// 5. Close connection
mysql_close($connection);
?>
The html file:
<html>
<head>
<script type="text/javascript src="myscript.php"">
//if clicked Yes open new page if Cancel stay on the page
function popup(){
var r=confirm("echo the php query here");
if (r==true)
{
window.location = "http://example.com";
}
}
</script>
</head>
<body onload ="popup()">
</body>
</html>
