Displaying result of multiple checkboxes

Anon

Hello

The situation is...

After running an MySQL query the results are output in rows with a checkbox for each row and with the Primary Key as the value.

I am trying to find a way to list the results of all checked boxes. No matter what I do I only get the value of the last box checked.

Results of the initial query on the first page formatted as a form...
<td><input type='Checkbox' value='$n1' name='checkbox'></td><td>etc.</td>...

Using many variations of a FOR Loop on the second page (also have tried a lot of WHILE loops)...
for ($i = "0"; ; $i++) {
echo "$checkbox<br>\n";
}

(and obviously, this example takes that last value and repeats it forever).

Thank you for any help.

if you call your name your check boxes checkbox[] this will automatically put all checked box into an arrary called $checkbox.
Then just use a for each loop to see which boxes have been checked.

Hi Richard,
While generating the output you need to name check boxes in this way

in the while loop use this
$count++;
$chk_name="check".$count;
<input type=\"checkbox\" name=\"$chk_name\" value=\"$n1\">

after the while loop set one hidden field
<input type=\"hidden\" name=\"tot_flds\" value=\"$count\">

In second page you need to gothrough for loop like this
for($i=1;$i<=$tot_flds;$i++)
{
$fld_name="check".$i;
if($$fld_name)
{
// do whatever you want
}
}

Hope this helps.......

Thanks John

That helped. Now I get a long list of \"Array\" output which tells me on on the right track but now to get the values out individually.

I\'m new to loops especially for loops especially when it\'s dynamically generated.

Still a little mixed up from beginning PERL too. Foreach seemed clearer.

I\'ll have to do some more study on this.

Hi,
What John suggested also can fullfill your job in that case you need to write a for loop in the second page like this
for($i=0;$i<sizeof($checkbox);$i++)
{
if($checkbox[$i])
{
// do whatever you want.to get the vale you simply need to use $checkbox[$i]
}
}
