[RESOLVED] how to retreive url passed variable?

[IceRegent]

I am having a problem retreiving a variable that has been url-encoded from a previous php href link. I have a script that passes a variable, but is it doen right? And, how do I get the variable in the new page? The code is as follows for the passing:

$passproj = urlencode($row['file']);	  			
    	echo '<table width="100%" border="2" cellspacing="2" cellpadding="2" bgcolor="#84BBD9" bordercolor="#400000">';
    	echo '<tr>';
    	echo '<td width="20%">' . $row['UserID'] . ' </td>';
    	echo '<td width="20%">' . $row['file'] . ' <a href="project_contrib.php?$passproj" target="_self"><input type="button" value="View"></a></td>';
    	echo '<td width="20%">' . $row['OrigProj'] . ' </td>';
    	echo '<td width="20%">' . $row['OrigUser'] . ' </td>';
    	echo '<td width="20%">' . $row['ProjDate'] . ' </td>';
    	echo '</table>' ; 

This ends up having a 'View' button added at the end of my file name in my table, and you click on the button and it takes you to that php page with the url encoded variable attached to the url.

The URL ends up looking like this:

http://www.mysite.com/project_contrib.php?$passproj

Is this correct to send and if not, what is the way to do it, but if correct, how do I retreive it in the next php script?

help!

It's not correct. There are a couple of things your doing wrong but you're on the right track. Let's start with this part of your code.

' <a href="project_contrib.php?$passproj" target="_self"><input type="button" value="View"></a></td>'

The first problem here is that you've got $passproj enclosed in single quotes so the variable "$passproj" isn't being expanded. The second thing is that you need to give the variable a name that you want to pass to the next page. For example, "passproj=$passproj". Here's what it should look like.

' <a href="project_contrib.php?passproj=' . $passproj . '" target="_self"><input type="button" value="View"></a></td>'

Use the $_GET superglobal to retieve the value of passproj in the next page.

My eyes have been opened! It is so frustrating that something so small as that can nix the whole attempt, but I am learning this from scratch as I go. The method that you described, I just applied, and was able to pass and retreive the variable. Everything that I learn, and utilize correctly, I am able to incorporate in for new code and pages, and this is getting me more on the way to where I want to be all the time. I appreciate the pointing in the right direction SAMUDASU!

Thanks!

Yeah, it's frustrating but we've all been there. Now you know and you'll be able to point others in the right direction. Anyways, glad i could help.
