Simple problem; passing variable to next page

kilbey1

I have a simple variable set up on page 1, ie.

$info = "\n\n<input type=\"hidden\" value=\"". $row[name]." by ".$row3[manufacturer_name]."\">\n";
echo $info;

Now, I want to echo it out on page 2 as a hidden field again. So on page 2 I've put:

switch($_REQUEST[mode]){

///////////////////////////
case "info":
	$info = "\n\n<input type=\"hidden\" value=\"". $row[name]." by ".$row3[manufacturer_name]."\">\n";
break;
default:
}


if(!isset($send)) { 

echo $info;
display_contents();

} else {
//more code here...

See where I'm trying to echo that $info again? Well, nothing comes out, even though it came out on Page 1.

How can I get the same stuff to come out on Page 2?

don't forget to use

echo $HTTP_POST_VARS['info'];

echo $HTTP_GET_VARS['info'];

depending on the way you pass the vars to another page.

Well, that didn't work, even when putting my text link into a form.

RedDragon

did you submit your data over a form or over a simple text link?

I did add a name field this time, maybe I'll strike gold soon. 🙂

If a form is actually being submitted across both of the scripts, it seems that it oughtta work...if you put stuff into a form, it must have an action attribute, a method attribute, and it must be submitted with some type of action link or button. That said, it's difficult to tell from what's posted here why it's not working. I don't see enough code to let me in on it.

Generally, if you want to have data available to a number of different scripts, you do one of these three things instead of pass-pass-pass, which can get pretty complex:

put it into a text file and read it again later.
put it into a database and read it again later.
store it in a cookie or session variable.

Assuming you're coding in a relatively recent version of PHP, you oughtta be able to:

session_start();
$_SESSION['info']=$info;

when you first set the variable, and then

session_start();
$info=$_SESSION['info'];

on any other page upon which you want to use the $info variable, and it will be available...the quid pro quos, of course, are do you really want to be calling session_start all the time, and is the data really that important....

RedDragon, here's how I've got Page 1 set up:

$info = "\n\n<input type=\"hidden\" name=\"info\" value=\"". $row[name]." by ";

//code here, then $info continues...

$info .= $row3[manufacturer_name]."\">\n";

echo "\n<form name=\"form1\" action=\"contactus.php\" method=\"post\"><center><p align=\"center\"><a href=\"contactus.php?mode=info";

echo "\"><font color=\"Red\"><b>Get Information</b></font></a>";

echo $info;

echo " | <a href=\"contactus.php\"><font color=\"Red\"><b>Contact Us</b></font></a></p></center></form>\n";

So... text link inside a form field currently. I don't remember if that works or not.

dalecosp,

I see what you're getting at. I was thinking I may need to create my variable $info, then put that $info into a 'holder' of some sort. But I know nothing about turning variables into anything else like that.

Here's my goal:

There are two links at the bottom of the page, 1. More Information, and 2. Contact Us

I want to re-use the Contact Us page. If the user clicks More Info, it goes to the contact page but an extra $info field is tacked on upon submission, for the recipient only.

You can view the page in action:

http://www.izzymillerfurniture.com/category_result.php?nid=49

and choose More Information.

Hi, kilbey,

POST method requires a submission....

<input type=submit>

If you want them to click the link, use GET, and arrange the
URL thusly:

echo "<a href=\"www.mysite.com?info=$info\"";

HTH,

kilbey1

Ahh, thanks all. It's running wonderfully now. I did have to do:

echo "<a href=\"contactus.php?info=$info\"";

While I created my hidden field for the form in my next page:

echo "\n<input type=\"hidden\" value=\"".$HTTP_GET_VARS['info']."\">\n";

Thanks so much all!!

dalecosp

Much welcome art thou! 🙂

If we've been of any help...pass it on!
