Passing variable value to iframe

Lauj

How do I pass a variable value from a hyper link to a .php file that is in the iframe tag? The second question is, how do I send a value in the iframe .php file back to the page that contains the iframe?

Any help is appreciated!

In the src attribute of the iframe u can pass values through get method like: <iframe src="mypage?variable=value">

You can use javascript to reload the content of the iframe with the desired value through get.

Many thanks for the help but I still can not get it work. Below are my codes that are on the maingpage.php:

<?php require_once('Connections/alumniConnection.php'); ?>
<?PHP
	if(!isset($HTTP_GET_VARS["sectionID"])){
		$sectnID = $HTTP_GET_VARS["sectionID"];
		if ($sectnID != ""){
			setcookie("whichSection", $sectnID, time()+3600);
			}
		}
	else{
		$dfrntSectionID = $HTTP_GET_VARS["sectionID"];
		$sectnID = $HTTP_COOKIE_VARS["whichSection"];
		if ($dfrntSectionID != $sectnID){
			$sectnID = $dfrntSectionID;
			}
		}
//*************************************************************************************
	$self = $HTTP_SERVER_VARS['PHP_SELF'];
	$pixID = $HTTP_GET_VARS["imageID"];
	$hdnPixID = $HTTP_POST_VARS["hdPixID"];
	$btnClicked = $HTTP_POST_VARS["btnClick"];
	$numPicsID = array();
//*********************Connect to database and query**************
mysql_select_db($database_alumniConnection, $alumniConnection);
if ($sectnID != ""){
	$query_rsSection = "SELECT * FROM photoGallery WHERE sectionID = ".$sectnID;
	$rsSection = mysql_query($query_rsSection, $alumniConnection) or die(mysql_error());
	$totalRows_rsSection = mysql_num_rows($rsSection);
	$numOfPics = array($totalRows_rsSection);
	}
//******************in the body tag****************************
	if ($sectnID !=""){
		$numOfCells=1;
		}
	if ($totalRows_rsSection >0){
		if ($numOfCells ==1){
			$src = 'galleryThumbNail.php';
			echo '<iframe src="'.$scr.('?var='.$sectnID:'').'" id="thumbnail" width="535" height="100" frameborder="0" scrolling="auto" name="myInlineFrame"></iframe>';
			}
		}
	else{ message();}
?>

The error occurs on this line

echo '<iframe src="'.$scr.('?var='.$sectnID:'').'" id="thumbnail" width="535" height="100" frameborder="0" scrolling="auto" name="myInlineFrame"></iframe>';

What I'm trying to do here is passing the variable $sectnID to the myIframePage.php page that is in the iframe.

Any help is grateful!

Your error is here

('?var='.$sectnID:'')

What are u trying to do ?

If you want only to concatanate ...

Use

$scr.'?var='.$sectnID

And the error is cleanned

Thanks! I got it figured out. I saw a few errors in that line now. The first part is working now.

Now here's the second part.

I am trying to display the thumbnails inside a iframe on the left side vertically, once the user click on the thumbnail image, pass the ID to a variable. This ID variable will be used to query the database to display the full picture on a table that is on the right side or main area. Right now the full picture is being displayed right below the iframe which is on the left side and the right side or main area contains nothing. I wonder if _parent means return back to where ever iframe was called.

Here's the code I used to pass the variable back to the _parent page.

echo '<a href="index.php?var=' . $blah . '" target="_parent">';

And this code returns the value but it returns to the lesft side of the page where the iframe was called and I want the full picture to be display on the right side or main area. Can this be done?

Okay, here's my code:

<?php <?php
	//***************************************This section displays the submenu of each section*****************************
	if ($totalRows_rsSection >0){
		$src = 'galleryThumbNail.php';
		//echo "<p></p><p></p>";
		echo '<iframe src="'.$src.('?var='.$sectnID).'" id="thumbnail" width="209" frameborder="0" name="myInlineFrame"></iframe>';
		}
	else{
?>			
			<!-- InstanceEndEditable --></td>
            <td rowspan="2">&nbsp;</td>
            <td height="219" valign="top" bgcolor="#FFFFFF">
			<!-- InstanceBeginEditable name="Body" --><span class="headline01">PHOTO GALLERY</span><p></p>
<?PHP
	message();
	}
	//****************************************Display the full picture below here******************************************
?>

Now, the problem is when the full picture is display, it displays above these

		<!-- InstanceEndEditable --></td>
        <td rowspan="2">&nbsp;</td>
        <td height="219" valign="top" bgcolor="#FFFFFF">

lines of code instead of below it like the way I have in my code.
