just want to make sure I'm going in the right direction with this. I have an image which I want to be replaced/changed if the value of a variable is either 0/1. So here is the code from the guy doing the server side stuff.
<?php
//Requires mysql_connect to create the connection
$link_state = 0;
//If you so wish you don't have to check for a connection, but may be a good idea leave this in.
if ($mysql_connection['connected'] == true) {
$result = mysql_query("SELECT * FROM link");
//The bit we are looking for should be the first row, and we should only get one row
$count = mysql_num_rows($result);
if ($count <= 0) {
//Interesting...
$mysql_error['error'] = true;
$mysql_error['description'] = "ERROR: No rows were returned from table 'link'";
} else {
//We should be ok to continue
if ($count > 1) {
$mysql_error['error'] = true;
$mysql_error['description'] = "WARNING: Found more than one row in 'link' table!";
}
$row = mysql_fetch_array($result);
$link_state = intval($row['state']);
}
} else {
$mysql_error['error'] = true;
$mysql_error['description'] = "ERROR: No mysql connection!";
}
/*
After the completion of this page, $link_state will be one of two things:
* 0 = offline
* 1 = online
Throws to $mysql_error:
1 Warning
2 Errors
*/
?>
Okay, so I'm assuming by that little bit of code I will then have a value of either 0 or 1 in $link_state.
So from this can I then just do a simple inline script like this to get my relevant image?
<img src="img/<?=($link_state=="0"?"off.jpg":($link_state=="1"?"on.jpg":))?>" />
Any insight would be great :)
Thanks in advance.
