Why can you not pass the parameter in the url link of the new page using the
get variable?
Example
<form action="welcome.php" method="get">
Name: <input type="text" name="name" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
When the user clicks the "Submit" button, the URL sent could look something
like this:
http://www.w3schools.com/welcome.php?name=Peter&age=37
The "welcome.php" file can now use the $_GET variable to catch the form data
(notice that the names of the form fields will automatically be the ID keys
in the $_GET array):
Welcome <?php echo $_GET["name"]; ?>.<br />
You are <?php echo $_GET["age"]; ?> years old!

Subject: [PHP-WIN] Can't seem to transfer a dynamically chosen parameter to
next page
I hope someone has an answer to what has been a thorny problem for me. I am
still junior to using PHP.
I have a script that displays a bunch of woody botanical orders out of a
MySQL file nicely in columns.
That part works fine.
Next what is wanted is for a user to be able to click on one of them, the
result being that it would open up a new page that would get details on the
woody order the person chose out of another MySQL table.
Well .... I got it to link to a page that opens up ok ---- except after
numerous attempts and ways I cannot get the name of the chosen woody order
to transfer to this next page.
- the examples I have seen on the Internet and book use static
information for the better part while the
very parameter that needs to be passed is derived dynamically. I
am fairly sure that is complicating
things more.
- Cookies would be an overkill and have too much persistence. I
believe using "session" would be overkill,
too, even if it might work. All I need is to make the choice the
reader makes go global enough to use it
in the very page that it calls. It is then also used both for
titles on that page (dynamic) and to do a
query for information to display on that chosen order. Writing to
a file seems to be an inefficient way if
there is only a way to just make it be memory resident instead.
The running copy can be seen and tried (to the degree it is working so far)
at:
http://www.prowebcanada.com/taxa/viewallorders.php
The files used are viewallorders.php and the response page of showorder.php.
I will add these as attachments.
What *will* work? Hope someone can help.

I haven't looked at your code, but it sounds like you need JavaScript.
On the page you are going to you will need to pass something. You can
pass values either through forms or through the URL. URL may be easiest.
If you have a link like http://somehost.com/page_two.php?variable=value
you can get the variable=value part from the $_GET array. Like this
$_GET['variable'] will equal 'value'. On your first page you can then
use JS to set the url for a link to include the value you want to pass.
I don't know how involved the page is, but you can use PHP to generate
the page and create the links with the variable=value part already on
them. i.e.
<a href="http://somehost.com/page_two.php?variable=value";>value</a>
<a href="http://somehost.com/page_two.php?variable=value2";>value2</a>
<a href="http://somehost.com/page_two.php?variable=value3";>value3</a>
<a href="http://somehost.com/page_two.php?variable=value4";>value4</a>

Why would you need JS to set the url for the link. Why could it not all be
done via php?

In showorder.php you have:
Echo "<title>Information on ordername . $ordername"; //actual order
name still not
// transfering properly yet. Different attempts made.
Echo "</title>";
echo "Debug statement: Chosen order is . $ordername . $name"; // debig
statement only. Remove later.
$ordername has to be initialized to your query string variable. Thus,
$ordername = $_GET['name']. But this also requires a small change in
viewallorders.php so that a query string parameter of name is set:
echo "<a href='showorder.php?$name '>";
The above line should be changed to:
echo "<a href='showorder.php?name=$name'>";

If you create a dynamic page with elements changing based on AJAX DB
queries and such you must be able to change the page from within the
local browser. That requires JS. I think that may be a little advanced
for what the OP was trying to accomplish, but I only mentioned it
because it can make for a more interactive page.
The example with value{2,3,4} shows how to do static links and can be
done only with PHP.

Hello
Why would you want to do that with a query string? All form data is
passed on the variables $_POST or $_GET and that is supposed to function
like that.
A query string has a totally different purpose under html...

parameter to next page
Date: Tue, 17 Mar 2009 11:54:07 -0400
Why can you not pass the parameter in the url link of the new page using the
get variable?
Example
<form action="welcome.php" method="get">
Name: <input type="text" name="name" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
When the user clicks the "Submit" button, the URL sent could look something
like this:
http://www.w3schools.com/welcome.php?name=Peter&age=37
The "welcome.php" file can now use the $_GET variable to catch the form data
(notice that the names of the form fields will automatically be the ID keys
in the $_GET array):
Welcome <?php echo $_GET["name"]; ?>.<br />
You are <?php echo $_GET["age"]; ?> years old!

What *will* work is understanding how HTTP works and where variables
come from within a script. For this you need to read up on it - I'm
sure Google can find you a basic introduction to web development.
As for your current problem please ignore all talk of JS and forms,
neither of which are needed. In viewallorders.php where you have...
echo "<a href='showorder.php?$name '>";
...change it to...
echo "<a href='showorder.php?ordername=".urlencode($name)."'>";
Then in showorder.php that value will be available in
$_GET['ordername'], so for example your debugging statement would
change from...
echo "Debug statement: Chosen order is . $ordername . $name";
...to...
echo "Debug statement: Chosen order is ".htmlentities($_GET['ordername']);
Notice how I'm encoding the value going into the URL and escaping it
when it gets echo'd back to the browser. This is important for
security reasons. For more on that please read
http://phpsec.org/projects/guide/.

Hello Bill
I mixed up names and ended up answering the wrong message. Sorry.
Actually it is quite easy...
In viewallorders.php you should replace:
echo "<a href='showorder.php?$name '>";
with
echo '<a href="showorder.php?&name=' . $name . '">';
and then, in showorder.php
<?php
parse_str($_SERVER['QUERY_STRING'], $qs);
$name = $qs['name'];
and that's it!
Now, the strings passed through this method are insecure. You should use
a parser function to clean or sanitize them (like urlencode/urldecode).
Cheers

What have you been smoking? This is already done for you, and the
results are in $_GET. Why duplicate the work?
