How would I intergrate Javascript with php

Ray · Jun 30, 2005

how would i intergrate javascript into the php brackets, i cant get it to work right, even when i change the "'s to \".

can some one please help me

stscac · Jun 30, 2005

you just need to use a ' to wrap the javascript and \' to hide markup script. Give me an example and ill take a shot

#connect to MySQL
$conn = @mysql_connect("localhost","---","-----")
or die("Could not connect to MySQL");
#select a database
$db = @mysql_select_db("template_users",$conn)
or die("Could not select database");

#create the SQL query
$sql = "insert into pm (whoto,whofrom,subject,message)
values (\"$whoto\",\"$username\",\"$sub\",\"$msg\")";
$result = @mysql_query($sql,$conn)
or die("Could not execute query");

if($result)
{

<script type="text/javascript">


</script>

}else{
echo("failed");

?>

ok, you're problem is simple,you just forgot a couple lines of code - try this

PHP:

<?php
#connect to MySQL
$conn = @mysql_connect("localhost","---","-----")
or die("Could not connect to MySQL");
#select a database
$db = @mysql_select_db("template_users",$conn)
or die("Could not select database");

#create the SQL query
$sql = "insert into pm (whoto,whofrom,subject,message)
values (\"$whoto\",\"$username\",\"$sub\",\"$msg\")";
$result = @mysql_query($sql,$conn)
or die("Could not execute query");


if($result)
{
?>
<script type="text/javascript">

<!--
function delayer(){
document.location = 'members.php?page=messagebox';
}
-->
</script>
<?
}

}else{
echo("failed");

?>

let me know if that works

Can you paste the full code?

Ray · Jun 30, 2005

ok i fixed ther error, the problem was that i had put an else command in wrong. Anyway, did what you told me, except it does the same thing, I included a a screen shot. Also the javascript still dont work

The code im using is below

PHP:

 if($result)
{
 ?>
 <script type="text/javascript">

<!--
function delayer(){
document.location = 'members.php?page=messagebox';
}
//-->
</script>
<body onLoad="setTimeout('delayer()', 5000)">
 <?

echo("<font face=\"Verdana\" size=\"2\" color=\"#333333\">Your message has been sent.</font><p><font face=\"Verdana\" size=\"2\" color=\"#333333\">You are now being redirected to your<a href=\"members.php?page=messagebox\"><font color=\"#333333\">message box</font></a>.</font></p>");


 }
}
?>

Screen Shot of problem

instead of the javascript, you should use:

PHP:

<?php
header("Location: http://www.address.ext/members.php?page=messagebox");
?>

and keep everything in php - unless you have a valid reason for using js

well, the reason i use java for that is that i cant figure out how to have a timed redirection in php. Also my other reason for using java is googles adwords...

axilant · Jul 1, 2005

could use sleep()

gamex · Jul 1, 2005

if you use the php redirection, you can only use it if there is no output, otherwise you will get an error say the headers have already been sent out.

Ray · Jul 1, 2005

thats not always true. The ob_start() command will buffer the headers so headers can be sent. Im great with php, just havin issues on things i never did.

PHP:

<?
if($result) { 
?> 
		<script type="text/javascript"> 
		<!-- 
		function delayer(){ 
		document.location = 'members.php?page=messagebox'; 
		} 
		//--> 
		</script> 
		<body onLoad="setTimeout('delayer()', 5000)"> 
		<? 
		echo ("<font face=\"Verdana\" size=\"2\" color=\"#333333\">Your message has been sent.</font><p><font face=\"Verdana\" size=\"2\" color=\"#333333\">You are now being redirected to your <a href=\"members.php?page=messagebox\"><font color=\"#333333\">message box</font></a>.</font></p>"); 
		//here print the rest of your html code
		//i suppose :
		echo ("</body>\n</html>");
		//these 2 lines help u a lot
		exit;
		die;
	}
} //we think that u open a condition before 'if($result) { '
?>

or you can write this (it's better for browser don't support javascript and more security)

PHP:

<? @session_start();

//---- your code

	if($result) { 
		$_SESSION['page']='messagebox';
		print "\n<meta http-equiv=\"refresh\" content=\"1; URL=members.php\">\n</head>\n<body>\n<br><br><br><font face=\"Verdana\" size=\"2\" color=\"#333333\">Your message has been sent.</font><p><font face=\"Verdana\" size=\"2\" color=\"#333333\">You are now being redirected to your <a href=\"members.php\"><font color=\"#333333\">message box</font></a>.</font></p><br>If nothing happens, <a href=\"index\">click here</a>.<br><br><br><br><br>";
		//here print the rest of your html code
		//i suppose :
		print "</body>\n</html>";
		//these 2 lines help u a lot
		exit;
		die;
	}
} //we think that u open a condition before 'if($result) { '
?>

and in members.php u can put something like :

PHP:

<? @session_start();
	if ( (isset($_SESSION['page'])) && ($_SESSION['page']=='messagebox') ) { 
		//content of members.php?page=messagebox
	}	
?>
