Hello,

I am creating radio buttons with the code below.
Visitor has to choose one thing with JavaScript.
How do I do? I am inexperienced. Please, Can you give me an example one of codes?

      <?php
      while ($row = mysql_fetch_array($quadlnbsistem_tipi)) {
      ?>
    <tr>
      <td class="table_body2" width="30%"><?=$row['lnb_markasi']?></td>
      <td class="table_body2" width="27%"><?=$row['lnb_tipi']?></td>
      <td class="table_body2" width="26%"><?=$row['lnb_cikisi']?></td>
      <td class="table_body2" width="8%"><?=$row['lnb_fiyati']?><?=$row['lnb_para_birimi']?></td>
      <td class="table_body2" width="9%"><input type="radio" value="<?=$row['id']?>" name="secilenlnbtipi_id"></td>
    </tr>
    <?php
     }

<script type="text/javascript">
function validateForm(frm){
var radios=frm.secilenlnbtipi_id; //radio button as an array-like object

Correct the typo:
for(var i=0; i<n; i++){
if(radios.checked]) return true;

into
if(radios.checked) return true;

learn to use the javascript console in your web browser to spot those syntax errors and make corrections.

The Javascript in the opening form tag: onsubmit="return validateForm(this)"
should be left as is. Do not replace the "this" by "frm"

Ok First of all learn to close your input tags
<input type="something" />

Then for groups, just change the name in <input> like ...

<p>Member for group 1<input type="radio" value="v1" name="group1"></input></p>
<p>Member for group 1<input type="radio" value="v1" name="group1"></input></p>
<p>Member for group 2<input type="radio" value="v1" name="group2"></input></p>
<p>Member for group 2<input type="radio" value="v1" name="group2"></input></p>
<p>Member for group 3<input type="radio" value="v1" name="group3"></input></p>
<p>Member for group 3<input type="radio" value="v1" name="group3"></input></p>

Both groups need to control for the select are required

<script type="text/javascript">
function validateForm(frm){
var radios=frm.secilenkablotipi_id;
var n=radios.length; 
for(var i=0; i<n; i++){
if(radios[i].checked) return true;
}

alert('You must choose one item');
return false;
}
</script>

while ($row = mysql_fetch_array($1groupradios)) {
radios group1
}

while ($row = mysql_fetch_array($2groupradios)) {
radios group2
}

Thanks
