Echo Multiple Values From One Form Element Name?

[wpearsall]

hey ya,

OK Say i have this form:

<form action=form.php method=post>
<input type=checkbox value=1 name=MiD><BR>
<input type=checkbox value=2 name=MiD><BR>
<input type=checkbox value=3 name=MiD><BR>
<input type=checkbox value=4 name=MiD><BR>
<input type=checkbox value=5 name=MiD><BR>
<input type=checkbox value=6 name=MiD><BR>
<input type=checkbox value=7 name=MiD><BR>
<input type=checkbox value=8 name=MiD><BR>
<input type=checkbox value=9 name=MiD><BR>
<input type=submit><BR>
</form>

how can i loop thru the values, etc, and do an echo for each value, if the chkbox is checked?

(Sorta like Yahoo! Mail does with its delete & Move ETC?)

Like, if some1 checks 1, 2, 3, 5, 6, and 9, - My PHP code, will then loop thru the checked value's, and delete a SQL Record from the MySQL Database, & Echo that the id was Deleted And so on, but for say 5, 7, and 8, nothing gets done, since they aint checked,..

: Hoping you know what i mean, and even more, how to do what i wanna do

technically it should be "MiD[]" (in quotes) and you would loop through it as if it were an array:

<?php
  for($i=0;$i<sizeof($_POST['MiD']);$i++)
    echo "MiD[$i] = {$_POST['MiD'][$i]}<br />\n";
?>

<?php
  // Loop through the length of the array 
  for($i=0;$i<sizeof($_POST['MiD']);$i++)
    // For each element print outs its value
    echo "MiD[$i] = {$_POST['MiD'][$i]}<br />\n";
?>

ok, so Thinking about this,

when the actual form is submitted as an array (like this),

is it automatically given its own array number, when its retrieved by PHP / The server,

Like if u use MyArray()=Split(Stuff,"?")

or something like dat then?

Yes when working with forms if you give them the same name and add [] to the end of the name it will turn it into an array, example:

<form action="form.php" method="post">
<input type="checkbox" value="1" name="MiD[]"><br />
<input type="checkbox" value="2" name="MiD[]"><br />
<input type="checkbox" value="3" name="MiD[]"><br />
<input type="checkbox" value="4" name="MiD[]"><br />
<input type="checkbox" value="5" name="MiD[]"><br />
<input type="checkbox" value="6" name="MiD[]"><br />
<input type="checkbox" value="7" name="MiD[]"><br />
<input type="checkbox" value="8" name="MiD[]"><br />
<input type="checkbox" value="9" name="MiD[]"><br />
<input type="submit"><br />
</form>
