eval() is your solution.
Advertising
for ($i = 1; $i <= $NMax; $i++)
{
$variable = "\$Check$i";
eval("\$string = \"$variable\";");
echo $string."<br>";
}

Subject: [PHP] Anyone Up?
Anyone Awake? Up?
I'm using 12 checkboxes
<INPUT TYPE="checkbox" NAME="Check1" VALUE="Your Name">
dynamically generated by mysql. Each has an id as primary index so I do
this:
<INPUT TYPE=\"checkbox\" NAME=\"Check".$mydata->id."\"
VALUE=\"".$mydata->yourname."\">
When I submit, I want to echo to see if anyone clicked on them. But I
can't get my variable right to find $check1 through $check12. How do I
express in a for loop. $Check.$i does not work of course!
for ($i = 1; $i <= $NMax; $i++)
{
echo $Check.$i"<br>";
}
:) Help
