retrieving id using button

[naughtybynature]

Hello
I would like to know if there's any possible code for retrieving
id when we use button. Normally the button itself will only
functions if we use form action, however if i only
used that form action i can't pass the id value to the next particular
form. Therefore, i usually used the link function to retrieve id.
For example :

$result = mysql_query("SELECT * FROM gred",@ $db);
$myrow = mysql_fetch_array($result);
 
echo "<a href=\"addform_obj.php?id=".$myrow["id"]."\">tambah </a>";
 
 
 

Hence I need the same function like the one that the above link did to retrieve id; but yet using the button.

$_REQUEST['id']

beter use
$id=mysql_fetch_field($field)

If you want the information from http://www.site.com/blah.php?id=section1&name=John&sec=9324

[PHP]
echo $_REQUEST['id'] . "<br>";
echo $_REQUEST['sec'] . "<br>";
echo $_REQUEST['name'];
[/PHP]
If purposely have them in a different order to show that the order doesn't matter.
The results from the above code are:

section1<br>9324<br>John
 

And would show as:

section1
9324
John



Good?

Maybe not to retrieving id using a button but...
to submitting values(id) sent to a page using a button (without <form>...</form>)
try this..

[php]
// --- main.php file ---
//..........
$result = mysql_query("SELECT * FROM gred",@ $db);
$myrow = mysql_fetch_array($result);

// echo "<a href=\"addform_obj.php?id=".$myrow["id"]."\">tambah </a>";

// button to replace your link
echo "<input type=\"button\" value=\"Tambah\" onclick=\"location.href='addform_obj.php?id=".$myr ow["id"]."'\">";
//..........
[/php]
[php]
// --- example addform_obj.php file ---
$var = @$_GET['id']; //catch the "id"
echo "variabelnya : $var";
[/php]

GOOD LUCK...

naughtybynature: I can no longer follow this discussion, as I think it is way off your original question. So that's why I ask you: is your problem/question solved/answered in any way or do you still have an issue open? And if so, could you explain what is still to be answered.

Thanks,

Ronald :cool:
