I am having trouble with variable variables;
I want to create a form as follows :-
<?
$result = mysql_query("SELECT * FROM name_and_email");
$num = mysql_numrows("$result");
if ($num!="0") {
$i = 0;
PRINT "<FORM action='test.php'>";
WHILE ($i < $num) {
$name = mysql_result($result,$i,name);
$email = mysql_result($result,$i,email);
$id = mysql_result($result,$i,id);
PRINT "<INPUT type='text' name='name$id'
value='$name'>";
PRINT "<INPUT type='text' name='email$id'
value='$email'><BR>";
$i++;
}
PRINT "<INPUT type='submit'></FORM>";
}
?>
## THIS SHOULD SUBMIT SOMETHING LIKE THIS >>>>
test.php?name1=avalue&email1=avalueagain&name2=secondname&email2=secondemail
THE PROBLEM:
From PHP with variable variables, how do I change $name1 and $email1 into -
## for all $name.$x values do this......
$sql = "UPDATE name_and_email SET name = '$name1', email = '$email1' WHERE
id = '$id'";
Many thanks if someone can help,
