Getting to input=text data without using

Anon

Within my code I have a number of lines like:
echo "<input type=\"text\" name=\"somename\" value=&myrow[some_value]> etc

Although initially $somename contains the value of $myrow[some_value], if I enter new text into the text field 'somename', the variable always contains the old values.

Can I get my hands on the new values easily without having to resort for processing it as a form?

I use form processing extensively elsewhere, but in this case it is not appropriate.

Many thanks

no because the php engine cannot see user input, only what the browser has sent in the form of a URL or form submittion.
Only JavaScript is able to see user input as they type it.

Thanks
(I suspected as much)
Perhaps you can confirm why I don't think I can use a form to solve this problem as well.
I have retrieved some data from mysql and am populating a table with it, from a loop.
echo <table>
echo <form name=myform action=$php_self?ID=$mydata>
while(loop)
echo "<td><input type="text" name=mydata value=$array[data]></td>
echo <td><input type=submit value=edit name=submit></td>
end loop
</form>
</table>

If I now have a table with more than one row, and select the edit button, the data passed by the form always equals the last record in the loop ( and not whichever one I selected).
Any ideas what I am doing wrong ?

Thanks again

I think the easiest way you could do it is to have the <form> tag within the loop, so effectively each input field and each button is in its own form, so only those values will be set, so you would have:

?>
<table>
<?
while (loop)
{
?>
<form name=myform action=<?=$PHP_SELF?>?ID=<?=$mydata?>>
<td><input type="text" name="mydata" value=<?$array[data]?>></td>
<td><input type="submit" value="edit" name="submit"></td>
</form>
<?
}

You might notice that i haven't used any echo statements, thats because for any reasonable lenght of html output its better to escape from php (just using a closing ?> ) type html, then back into php when neccessary (using <?). The <?=$var?> is a shortended way of saying <? echo $var ;?>
