html inputs

chrisleon

I have some html inputs:

name="emp1"
name="emp2"
name="emp3"

etc.....

I would like to pass these inputed variables to a php script that builds them dynamically, and I do not have to hard code the variables.

If someone can help, please, I need it

If you send them via form (you do know how to use forms, don't you?) to the PHP script, they should be $emp1, $emp2 and $emp3 inside the script.

I do know how to use forms, but my question is this:

I have <input type=text name=emp1> etc..

in my script I want to do something like this

$i = 1

foreach{
echo <table>
echo <tr>
echo <td>$emp[$i]</td>
echo </tr>
echo </table>
$i++
}

Therefore it would build the emp1 2 and 3 without have to build a table for each variable. The code above does not work exactly how I want, and I was hoping for a better way. Do you have any suggestions

If you want to have all of the values in a single array and reference them in the manner you describe, simply give all of your form fields the same name ending in []. For example:

Thus, each field with the name emp[] will have its value added to the array $emp[]. Make sense?

note that automatic numbering starts at 0.

an alternative:

if you name the inputs
inp1
inp2
inp3
etc.,

you still can process them in a loop using variable variables:

for($i=1; $i<=$totalnumberofinputs; $i++)
echo ${"inp".$i};

Ok, you guys have been so helpful, but I have one more snag, here is my php script, and it is displaying those input values in my address bar for IE5.0

<head>
<title>Chris' Cell Page</title>
</head>
<body>
<table border="1">
<?php
for($i=1; $i<=$totalnumberofinputs; $i++) {
print ("<tr>\n".
"<td>${"emp".$i}</td>\n".
"</tr>\n");

}
?>
</table>
</body>

I have three test inputs, emp1 emp2 and emp3
and I hit submit, and it passes the values, just not to the screen. It looks like this:
http://nicholasandco.net/PHP/cell.php?emp1=2&emp2=2&emp3=2

can you tell me what I am doing wrong.

Chris, having used matto's code, you need to set $totalnumberofinputs to the number of fields (emp1, emp2, etc.) you have, or the code won't print anything.

it worked, and I just want to say thank you again for all your help, I really appreciate it!
