[RESOLVED] How the dfhdsf do you get php variables in javascript

[coldwerturkey]

I really don't like posting easy questions because I hate spoon feeders, but I've read about 15+ articles and cannot for the life of me figure this out,

How do you pass variables into javascript???

echo '
<style type="text/javascript">
var fadeimages=new Array()
fadeimages[1]=["[COLOR="Red"]{$here}[/COLOR]", "[COLOR="Red"]{$andhere}[/COLOR]", ""]
...
</style>
';

thank you, I'm having such troubles w/ this, any proof of example helps,

In this case it looks like you are just trying to print the contents of some PHP variables. Since you are using single quote delimited strings, you should use concatenation (or pass multiple arguments to echo).

echo '<style type="text/javascript">
var fadeimages=new Array()
fadeimages[1]=["' . $here . '", "' . $andhere . '", ""]
...
</style>';

As laserlight eluded to, variable interpolation occurs within double quotes.

Follow up question:

$query = mysql_query("SELECT * FROM banners ORDER BY orderr ASC LIMIT 3");
while($row = mysql_fetch_array($query)) {
	echo 'fadeimages[' . $row['order'] . ']=["' . $row['banner'] . '", "' . $row['link'] . '", ""]';
}
//which prints:
              fadeimages[0]=["http://bannerlink1", "http://link1", ""]
              fadeimages[1]=["http://bannerlink2", "http://link2", ""]
              fadeimages[2]=["http://bannerlink3", "http://link3", ""]
//its the 3 numbers     ^  thats important, not ^^^^ that stuff

Everything works fine, but the $row['order'] (or "[#]") seems unessisary to me; i know the script needs it to work but, its just another field the user has to fill in a form, and could mess up. so. my question to you is, is there anyways for a php while loop to produce unique incremental numbers (0, 1 and, 2) to results as it spits them out?

[Kudose]

Sure ... MySQL can number the results for you.

Change

$row = mysql_fetch_array($query)

to

$row = mysql_fetch_array($query, MYSQL_BOTH)

That will return an array of results with both numeric and associative keys.

but than how do I get the #'s into

fadeimages["[COLOR="Red"]here[/COLOR]"]

?

nevermind I figured it out (all by myself 🙂)

for reference this is what I did:

$i = 0;
$query = mysql_query("SELECT * FROM banners ORDER BY id ASC "); 
while ($row = mysql_fetch_array($query)) {
	echo 'fadeimages[' . ($i+1) . ']=["' . $row['banner'] . '", "' . $row['link'] . '", ""]
	';
	$i = $i+1;
}
