"\n"); i think i see some code in that jungle. allow me to clean it up a bit! while ($result = mysql_fetch_array($dbresult_riderlist)) { echo <<<QQQ <tr> <td> <input type="hidden" name="rider_id[]" value="{$result['rider_id']}" /> <input type="text" name="rider_name[]" value="{$result['rider_name']}" size="15" /> </td> <td><input type="text" name="rider_license_cat[]" value="{$result['rider_license_cat']}" size="3" /></td> <td><input type="text" name="comments[]" value="{$result['comments']}" size="20" /></td> <td><input type="file" name="image[]" value="{$result['image']}" size="10" /></td> <td>Edit: <input type="radio" name="edit_rider_action[]" value="edit" /> Delete: <input type="radio" name="edit_rider_action[]" value="delete" /></td> </tr> QQQ; } > I'm trying to gather the data from this form and test the condition of > the radio button 'edit_rider_action'. > > I can traverse the form data array via $_POST and get the key/value > pairs but am not sure how to test the 'edit_rider_action'. well i think since you're doing a radio button you shouldn't have [] on the end of your field name in the first place. the [] creates a new element within an array, in your case an array called edit_rider_action. but because of the way radio buttons work you will never have more than one value for edit_rider_action so you don't need it turned into an array after the form is submitted. therefore the following code: <td>Edit: <input type="radio" name="edit_rider_action[]" value="edit" /> Delete: <input type="radio" name="edit_rider_action[]" value="delete" /></td> should be changed into: <td>Edit: <input type="radio" name="edit_rider_action" value="edit" /> Delete: <input type="radio" name="edit_rider_action" value="delete" /></td> after the form is submitted you can get to the value of edit_rider_action with: ( <?php $edit_rider_action = $_GET['edit_rider_action']; ?> note: if you submitted your form via post you'll need to use $_POST and not $_GET. hth, chris.
