Yes In know this has been covered in other ways, but after searching the forum I did not find a specific solution that fit my application. Maybe I overlooked something, so I'm sory if I did.
Here's what I have got. It's very simple (or at least should be). I have a page on my site that has a URL of: http://mysite.come/page.php?gid=1
And in that page I have an iframe that calls for the gid variable like this: -
<iframe src="family.iframe.php?gid=<?php echo $gid; ?>"
-
family.iframe.php is another page I have that has formatting and other stuff on it. I basically gets called over and over again until there is nothing left to display. This is not the problem though. I have this setup working in a different fashion elsewhere. Plus I can go directly to mysite.com/family.iframe.php?gid=1 and get the results I want on a full page. But I want it to go in that iframe I have created. Am I missing a bit of code that pulls the 'gid=1' from the url and inserts it into the 'echo' section? I have tried using the $var=$_GET method with no luck as well. Any ideas?

Heya, docebrown. Welcome to TSDN!
Please use CODE tags when posting source code. See the REPLY GUIDELINES on the right side of the page next time you post.
The correct syntax is: -
<iframe src="family.iframe.php?gid=<?php echo $_GET['gid']; ?>"
-
Sorry about that. Thanks for the correction. Does anyone have any idea as to why I can not grab the 'gid' variable?

Heya, docebrown.
This usually has to do with whether the register_globals directive is turned on in your php.ini file.
As a general rule, it is considered a good idea to not only know beforehand what the variables should be named, but also where they are coming from. For example, these three variables are distinct: -
$var1 = $_GET['gid']; // Passed in URL
-
$var2 = $_POST['gid']; // Generally passed as part of submitted form data
-
$var3 = $_COOKIE['gid']; // Stored in a cookie
-
If you are expecting your variable to be passed in the URL (i.e., $_GET), then you're probably not too concerned about security.
On the other hand, if you are doing sensitive stuff, such as changing User account information, you'll want to make sure that these values are passed via post so as to discourage XSS. In this case, it becomes important to be able to explicitly use $_POST['var'].
If you want register_globals-like behavior in your scripts, consider adding this line at the top:
Thanks for the help on this. I checked and that setting IS turned OFF and my admin won't change it. So I used your remedy and instead of just using the:
I used - <?PHP echo $_GET['gid']; ?>
and it works like a charm. Thanks for the explanation on the different ways to pass and pull vairables. I am not all that familiar with PHP and HTML, but I know enough to get myself into trouble. That explanation will help me in another area I am working on! Thanks again!

Heya, docebrown.
Glad to hear you got it working! Good luck with your project, and if you ever need anything, post back anytime :)
Hi guys,
I'm a bit of a PHP noob so patience is required :). I'm probably doing something basic incorrectly but I would like to use the variable called src1 in a url I either echo or use printf. its currently showing the iframe but no url for it.
You see I am taking variables from MySql and using them to change the url based on user input. I want to be able to take the php variable thats got the values from the database and then place this new url in the iframe.
Any Input would be greatly appreciated. Thanks - $src1 = 'somewhere;
-
$myVar = $_GET['src1'];
-
-
printf ('<html>
-
-
<iframe id="I1" name="I1" style="width: 892px; height: 450px" src=="http://www.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=<?PHP echo $_GET['src1']; ?> ">

That ain't too hard, friend. You've pretty much got it done, just not quite ;)
Doing <?php ... ?> inside a string will do sod all. Instead, you need to close the string, then call your variable, and then reopen your string.
Check out the following: -
$name = "mark";
-
-
echo "My name is ", $name, ". Nice to meet you.";
-
// Or (notice the difference in concatenation)
-
echo "My name is " . $name . ". Nice to meet you.
-
// The first option is faster.
-
Try and use this in your code.

Thanks Mate,
THis is my attempt at what your suggesting. Its not quite right yet (my attempt). - echo "<iframe SRC=\"" . "http://www.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=" . $lat_mins . "width="100%" height=\"100%\" frameborder=\"0\">If you can read this your browser does not support iframes.</iframe>";
