Syntax prob

aspect

i'm stuck with a syntax issue....

i want to set a VARIABLE with a value from a FORM

using this method

$ed = 'edit_username' . $row['id'];

result, i hope, would be edit_username1 then

$edit_username = $_POST['$ed'];

sets the variable from form field $ed

It doesnt work so i have obviously got the syntax wrong....

does anyone know how to do it please..

Your syntax is almost correct.

$edit_username = $_POST[$ed];

The reason is that variables within single quotes are not parsed.
You could use double quote delimited strings, but there isnt much point in doing that here.

aspect

thanks m8, but i did try that first... doesn't make a difference.

any other ideas

laserlight

In that case it isnt a syntax problem anymore.

You'll need to explain your script more, and perhaps provide a relevant code snippet.

aspect

no probs..

Basically i have fields on the form named things like
edit_username1
edit_username5

to save me doint the code x amount of times (1 for all 60 records)

i thought this would work but its just reading BLANK into edit_username when their is definatley something in the form field.

$result = mysql_query("SELECT * FROM users WHERE id>0");

if ($row = mysql_fetch_array($result)){
  do {
    $ed = 'edit_username' . $row['id'];
    $edit_username = $_POST[$ed];
    print $edit_username;

  } while($row = mysql_fetch_array($result));
}

the print string will be replaced by an line to update my DB once its working

Are you sure the name of the form field is $ed and not just ed?
<input name='$ed'> or <input name='ed'>? If it's ed then you'll need to remove the $ in laserlight's suggestion.

aspect

no m8.. field name are edit_username1, edit_username8 etc...

in other words the field name is also generated realtime

from this

echo 'edit_username'.$row['id']

anywayz.. i r a bit off a dumbass because it turns out that the prob was in the form...

echo 'edit_username'.$row['id']

this was wrong and should have been

echo 'edit_username'.$row['edit_id']
