[SOLVED] how to capture mutiple check box value in php

[klpang]

i have done a HTML form in php script. when i check 2 value in a check box, it just pass 1 value instead of 2 checkbox that i have checked.

i not sure what happen to my script. below is the script that i have done.

please point out the error that i have been made.

for(i=0;i<f.txtc.length;i++)
{
if(f.txtc[i].checked==true)
{
c++;
}
}

if(c==0)
{
alert("Please select 1 or more option in Question 3");
f.txtc[0].focus();
return;
}

if((f.txtc[6].checked==true)&&((Trim(f.txtcothers.value)).length==0))
{
alert("Please fill in the text box in Question 3");
f.txtcothers.focus();
return;
}

the check boxes cannot be the same name, only radio buttons. You have to label them name=txtc[] then a digit will be put in after.

but all the checkbox is under a same group. so how?

[craygo]

Check Boxes have to have different names. if you like name them txtc1, txtc2,txtc3, ect....

This is the best way:
[!--html--][div class=\'htmltop\']HTML[/div][div class=\'htmlmain\'][!--html1--]<[color=blue]input type[/color]="[color=orange]checkbox[/color]" name="[color=orange]txtc[][/color]" value="[color=orange]Value![/color]" />[!--html2--][/div][!--html3--]
[code]<?php
if ( isset( $_POST['txtc'] ) )
{
     print_r( $_POST['txtc'] );
}
?>[/code]
You will see all of the posted checkboxes
