passing variables using URL

bobby_rahman

hiya

I create a table by looping through a select query to return all the relevant rows:

using
while( $row = mysql_fetch_array($result) )
{
echo("
<tr $c>
<td><a href=\"view_bug.php?var1=$row['bugid']\">" . $row['bugid'] . "</a></td>

This creates a colum with all the bugids as hyperlinks. When I click on the hyperlink I go to the view_bug.page but I dont seem to be send the variable $bugid (The one I selected from the table)

any suggest why it aint working?

Cheers
Bob

You mean $var1, don't you? You don't pass $bugid...

Check PHP.INI... most likely register_globals = OFF. DON'T change that setting. Instead, refer to the variable using $_GET['var1'].

Thanx for replying so quick...

How can u explain $_POST to me.

as I have a main.php which in it includes "table.php" (this is a page which dynamically creates the rows depending on a mysql query which is created by the drop down boxes in main.) that is where the code was included from.

I am going mad trying to find how to access the $row['bugid'].
I can see them in the browser numbers starting from 0000001...0000011 but cant get at them.

Tried to pint them out - can see one number?
Not sure if I can use $_POST as this page included or am i missing the point?

Thanx
Bob

"How can you explain $_POST to me."?
By posting. 🙂

If you have a form with <input type='text' name='witch'>, the next page (the one specified in the form's action) will be able to access it with:
$_POST['witch']
If the method was post.

With your thing, you say:
<a href=\"view_bug.php?var1=blahblah
That means the variable is called var1. So you'd refer to it with... $_GET['var1'].

sorry to pester and be a total newbie but:

this is the link that creates all the bugid as links:

<a href=\"view_bug.php\">" . $row['bugid'] . "</a></td>

now to get the variable bugid which has been selected I assume I need to use a question mark.

<a href=\"view_bug.php?\">" . $row['bugid'] . "</a></td>

now I want the bugid so put in:
<a href=\"view_bug.php?bugid=$_GET['bugid']\">" . $row['bugid'] . "</a></td>

But this doesnt return anything in the URL. If this worked I would expect to see something like this in the url view_bug.php?bugid="0000001"

I think the problem is something to do with $row['bugid']...is there anyway I can GET what is stored in this?

This is what I can see

bugids display in browser:

| 1 | ----------------
| 2 | | show bug |
| 3 | --------------> view_bug.php | 2 |

| 4 | -----------------

Hey guys thanks for all the help....

More hcaking here in the UK has solved the problem after 4 hours!!!!!

the final line is:

<a href=\"view_bug.php?var1==$row[bugid]\">" . $row['bugid'] . "</a></td>

It was the quotation marks in $row[bugid] that was messing it up
(the one after the ?)

Geeze im feel stupid....thanx again
