Perhaps this example may help. Eg: a form with checkboxes and
submit button, a few are checked and I want to delete the
corresponding records from the database. The database table has an
ID column:
for each ($argv as $key=>$value) {
//$key is named cb_1 $value is "checked"
//to get 1 from the key name, then
//needed: function like nameof()
$var=nameof($key);
$ID=substr($var,3);
$query="delete * from dbtable where ID='$ID'";
//etc
}
Okay, your data is coming in from a form and you want to translate
that data to a php array -- here's how to do it:
In your form you use:
<input type="checkbox" name="a1">
<input type="hidden" name="whatever1" value="103">
<input type="checkbox" name="a2">
<input type="hidden" name="whatever2" value="206">
<input type="checkbox" name="a3">
<input type="hidden" name="whatever3" value="1187">
<input type="checkbox" name="a4">
<input type="hidden" name="whatever4" value="6101">
In your receiving php script, you use:
for ($i = 1; $i <= 4; $i++)
{
$a = 'a' . $i;
$b = 'whatever' . $i;
if($_POST[$a] == 'on')
{
my_array[] = $_POST[$b]
}
}
If a user clicks any/all of the checkboxes, then those checkboxes
will be turned 'on' and the values associated with the hidden fields
will come into play and be recorded in the my_array[].
A "count(my_array)" will provide you with the number of checkboxes
that were actually checked.
Sure you can do this in while statements if you wish, but the idea of
how to translate checkboxes to a php array is here.
The hidden values above could just as easily be values taken from a
database corresponding to record deletions, such as:
<input type="hidden" name="whatever4" value="<?php echo($record_ID");?>">
The point is that you can determine what the user clicked and tied it
to whatever you presented.
