appended variable names

[cfgcjm]

I have a dynamic form which you can view at http://digiconmediagroup.com/Homeplate/portal/form.php

Each of the fields is automatically named Time1 Food1 Time2 Food2 etc dependent on the number of times the user enters.

I'm eventually having this form emailed through php but I'm having trouble figuring out how to assign the variables. I know this doesn't work but it's the concept that i want to use. If anyone has and ideas on how to make something like this run in php it would be of great help...

<?php
$recur = $_POST['numberOfRows'];

for($i=0; $i<$recur; $i++)
{
$time$i = $_POST['Time$i'];
$food$i=$_POST['Food$i'];
$amt$i=$_POST['Amt$i'];
$scale$i=$_POST['Scale$i'];
$emotion$i=$_POST['Emotion$i'];
}
?>

Why not just use arrays?

You could just make them arrays?  Just put [ ] around the $i in your code that you have, example:

 

<?php
$recur = $_POST['numberOfRows'];

for($i=0; $i<$recur; $i++)
{
$time[$i] = $_POST['Time'.$i];
$food[$i]=$_POST['Food'.$i];
$amt[$i]=$_POST['Amt'.$i];
$scale[$i]=$_POST['Scale'.$i];
$emotion[$i]=$_POST['Emotion'.$i];
}
?>

 

I haven't really tried putting a variable like $i in to a $_POST before but I don't see why it won't work   Then you can access the different $time, $food etc like $time[0] (would return the first value of the array) etc.

ok thanks for the help, i didn't know if there way a way to do it without arrays or not. I've got a meeting now but i'll try it later and let you know...thanks

It is possible with eval(), but it's so much easier using arrays really.

 

<?php

$recur = $_POST['numberOfRows'];

for($i=0; $i<$recur; $i++) {

eval("\$time".$i." = \$_POST['Time".$i."'];");
eval("\$food".$i." = \$_POST['Food".$i."'];");
eval("\$amt".$i." = \$_POST['Amt".$i."'];");
eval("\$scale".$i." = \$_POST['Scale".$i."'];");
eval("\$emotion".$i." = \$_POST['Emotion".$i."'];");

}

?>

 

I believe that would be the code for creating it via eval, and each time you'd want to access it by a loop you'd have to use eval again etc.  It's just much simpler using arrays.

you can do it with "variable variables"

<?php
$times = array (1 => 12, 13, 14);

for ($i = 1; $i <= 3; $i++)
{
    ${'time'.$i} = $times[$i];
}

echo $time1 . '<br>';          // 12
echo $time2 . '<br>';          // 13
echo $time3 . '<br>';          // 14

?>

 

but arrays are easier to process
